Overview
Atrioventricular Canal Defect (AVCD) repair is an open-heart surgical procedure performed to correct a complex congenital heart malformation involving defects in both the atrial and ventricular septa along with abnormalities of the atrioventricular valves, typically achieving long-term survival rates exceeding 90% in specialized pediatric cardiac centers. GAF Healthcare connects international families with India's and the UAE's highest-volume congenital heart surgery programs, where board-certified pediatric cardiac surgeons perform complete AVCD repair using advanced techniques including the double-patch and single-patch methods with mitral valve reconstruction. Patients traveling through GAF Healthcare benefit from end-to-end coordination — from pre-operative cardiac workup to post-operative rehabilitation — at a fraction of the cost available in Western countries, without compromising on surgical outcomes or intensive care standards.
Hospital Stay: 10–16 days (including 3–5 days in the Pediatric Cardiac Intensive Care Unit, followed by 7–11 days in a monitored step-down ward) • Total Stay in Country (Fit-to-Fly): 4–6 weeks from the date of surgery (international air travel is cleared only after confirmed sternal healing, stable cardiac function on echocardiography, and cardiologist sign-off) • Success Rate: 92–96% (operative survival in high-volume centers for complete AVCD repair; outcomes are strongly correlated with surgical volume and the degree of pre-operative pulmonary hypertension)
What Is It?
Atrioventricular Canal Defect — also called atrioventricular septal defect (AVSD) or endocardial cushion defect — is a spectrum of congenital cardiac anomalies resulting from failure of the endocardial cushions to fuse properly during embryogenesis. The complete form involves a large ostium primum atrial septal defect, an inlet ventricular septal defect, and a common atrioventricular valve that spans both ventricles instead of the normal separate mitral and tricuspid valves. The partial (or incomplete) form typically presents with only the atrial component and a cleft in the mitral valve leaflet, while the intermediate or transitional form occupies a spectrum between these two. Approximately 40–45% of children with trisomy 21 (Down syndrome) have congenital heart disease, and complete AVCD accounts for roughly 45% of those cardiac defects, making it the most common serious cardiac lesion in this population.
The hemodynamic consequences of an unrepaired complete AVCD are severe and progressive. Left-to-right shunting at both atrial and ventricular levels causes pulmonary overcirculation, leading to volume overload of the right heart and early development of pulmonary arterial hypertension. The incompetent common AV valve contributes additional regurgitant volume, further stressing both ventricles and accelerating ventricular dilation and dysfunction. Without surgical correction, irreversible pulmonary vascular obstructive disease (Eisenmenger syndrome) can develop within the first 1–2 years of life in complete AVCD, closing the window for corrective surgery and converting a correctable lesion into a fatal one. Preoperative assessment of pulmonary vascular resistance using the Wood Units index is therefore mandatory in any child presenting beyond infancy.
The standard of care for complete AVCD is elective surgical repair between 3 and 6 months of age, before irreversible pulmonary vascular remodeling occurs. Partial AVCD repair is typically performed between 2 and 4 years of age. Surgical correction involves patch closure of the septal defects and reconstruction of the common AV valve into two competent valves — a technically demanding step that carries the greatest impact on long-term outcome. Centers in India and the UAE performing these repairs in high volumes (>150 congenital open-heart cases per year) demonstrate outcomes that are statistically comparable to data published by the Society of Thoracic Surgeons (STS) Congenital Heart Surgery Database.
Candidates
• CONFIRMED DIAGNOSES SUITABLE FOR REPAIR:
• Complete AVCD (ostium primum ASD + inlet VSD + common AV valve) in infants typically 3–6 months of age
• Partial AVCD (ostium primum ASD + cleft mitral valve) in children 2–4 years of age
• Transitional/intermediate AVCD assessed on a case-by-case basis by the surgical team
• Unbalanced AVCD with dominant left or right ventricle evaluated for single-ventricle palliation pathway (staged Fontan procedure) rather than biventricular repair
• Children with trisomy 21 (Down syndrome) and complete AVCD — this group benefits equally from repair and should not be denied surgery on the basis of chromosomal diagnosis alone
• REQUIRED PREOPERATIVE DIAGNOSTICS:
• Transthoracic Echocardiography (TTE) with Doppler: Defines the extent of ASD and VSD, common AV valve morphology (Rastelli classification: Type A, B, or C), degree of AV valve regurgitation, and ventricular balance
• Transesophageal Echocardiography (TEE): Used intraoperatively to confirm repair adequacy before chest closure
• Cardiac Catheterization with hemodynamic assessment: Mandatory in any child >6 months of age or with clinical suspicion of elevated pulmonary vascular resistance (PVR); calculates Qp:Qs ratio and PVR in Wood Units (operable if PVR index <8 Wood Units·m²)
• Chest X-Ray (CXR): Cardiomegaly, pulmonary plethora, and upper lobe vascular diversion indicate hemodynamic significance
• 12-Lead ECG: Classic finding of left-axis deviation (superior QRS axis, typically between -60° and -90°) and right bundle branch block pattern
• Complete Blood Count (CBC), Coagulation Profile (PT/aPTT/INR), Metabolic Panel, Blood Group and Crossmatch
• Pulmonary Function Assessment: Clinical and imaging-based; formal spirometry reserved for older children
• Genetic Karyotype (if not already performed): To identify trisomy 21 or other associated syndromes (e.g., heterotaxy/isomerism)
• Brain Natriuretic Peptide (BNP) or NT-proBNP: Objective marker of ventricular volume overload and heart failure severity
• ABSOLUTE CONTRAINDICATIONS:
• Established Eisenmenger syndrome (fixed, irreversible pulmonary vascular obstructive disease; PVR index ≥8–10 Wood Units·m² unresponsive to vasodilator challenge)
• Severe unbalanced ventricles precluding biventricular repair (assessed by ventricular volume ratios on echocardiography and cardiac MRI)
• Active systemic infection or sepsis at the time of planned surgery
• RELATIVE CONTRAINDICATIONS / HIGH-RISK FACTORS (requiring multidisciplinary team review):
• Significant prematurity or birth weight <2.5 kg (surgical repair may be deferred with medical management as a bridge)
• Severe associated non-cardiac congenital anomalies with poor overall prognosis
• Borderline PVR (6–8 Wood Units·m²) — pulmonary vasodilator challenge with oxygen and/or nitric oxide performed at cardiac catheterization to assess reversibility
Procedure
COMPLETE AVCD REPAIR — SURGICAL TECHNIQUES:
All complete AVCD repairs are performed under general anesthesia on cardiopulmonary bypass (CPB) with cardioplegic arrest. Median sternotomy is the standard access, though a ministernotomy approach is increasingly offered to older children and adults undergoing partial AVCD repair. The key surgical steps involve: (1) patch closure of the ventricular septal defect, (2) partition of the common AV valve into a competent left (neo-mitral) and right (neo-tricuspid) AV valve, and (3) patch closure of the atrial septal defect.
• TWO-PATCH TECHNIQUE (Modified Technique; Most Widely Used):
The VSD is closed with a separate Dacron or pericardial patch, and the common AV valve is divided and sutured to this patch at the appropriate level. The ASD is then closed with a second autologous pericardial patch. This technique offers independent and precise control of both the valve partition and the ASD closure, and is the preferred approach in most high-volume centers because it minimizes the risk of creating residual VSD and allows optimal valve leaflet coaptation. The cleft in the reconstructed left AV valve (neo-mitral valve) is closed with interrupted sutures — a critical step, as residual left AV valve regurgitation is the most common cause of reoperation.
• SINGLE-PATCH TECHNIQUE (Classic Technique):
A single autologous pericardial patch is used to close both the ASD and VSD simultaneously, with the AV valve leaflets sutured directly to the patch at the level of the AV groove. This technique is technically efficient but offers slightly less flexibility in valve leaflet adjustment. It remains appropriate in specific anatomical configurations.
• MODIFIED SINGLE-PATCH (Australian or 'Cleft-Closure' Technique):
In cases where the inlet VSD is restrictive or absent (partial/intermediate AVCD), the AV valve leaflets are sutured directly to the ventricular septum without a VSD patch, and only an ASD patch is placed. This simplifies the repair for partial forms.
• AV VALVE REPAIR CONSIDERATIONS — RASTELLI CLASSIFICATION:
The morphology of the superior bridging leaflet determines surgical strategy. Rastelli Type A (most common, ~75%): The superior bridging leaflet is divided at the midline and is well-anchored to the ventricular septum by chordae; valve partition is straightforward. Rastelli Type B (rare, ~5%): Chordae attach to a papillary muscle in the right ventricle; more complex. Rastelli Type C (~20%): The superior bridging leaflet is free-floating with no attachments to the septum, most common in trisomy 21; technically most demanding.
• ANNULOPLASTY AND VALVE AUGMENTATION:
In patients with significant left AV valve regurgitation, limited annuloplasty of the left AV valve annulus (using a partial ring or pledgeted sutures) is performed to reduce regurgitation. Pericardial augmentation of hypoplastic leaflets may be required. The goal is to achieve left AV valve regurgitation of mild or less on intraoperative TEE before weaning from bypass.
• MANAGEMENT OF PULMONARY HYPERTENSION PERIOPERATIVELY:
Children with elevated preoperative PVR receive inhaled nitric oxide (iNO) initiated in the operating room upon reperfusion, continued in the PCICU. Intravenous milrinone is routinely used for pulmonary vasodilation and right ventricular afterload reduction. Sildenafil may be initiated orally in the postoperative period and continued after discharge in high-risk patients.
• MINIMALLY INVASIVE AND ROBOTIC-ASSISTED APPROACHES:
In older children and adults with partial AVCD, robotic-assisted cardiac surgery (da Vinci Surgical System) and thoracoscopic (port-access) approaches are available at select centers in India (particularly in Chennai, Hyderabad, and Mumbai) and in Dubai. These approaches involve smaller incisions, reduced blood transfusion requirements, and faster sternal recovery. However, they are not appropriate for complete AVCD repair in infants due to anatomical constraints.
• PALLIATION FOR INOPERABLE OR HIGH-RISK CASES:
Pulmonary artery banding (PAB) is occasionally performed as a temporizing measure in very low-weight infants with complete AVCD and unacceptable surgical risk, to control pulmonary blood flow and prevent further pulmonary vascular remodeling, bridging the patient to definitive repair at a safer weight and age. PAB does not represent a definitive treatment.
• ADULT AVCD REPAIR:
Adults presenting with previously undiagnosed partial AVCD or failed childhood repair (residual defects, significant left AV valve regurgitation) are managed with re-operative cardiac surgery, which carries a higher risk due to pericardial adhesions and ventricular remodeling. Catheter-based closure devices (e.g., Amplatzer septal occluder) may be applicable for isolated ostium primum ASD components in carefully selected adult patients without significant AV valve pathology.
Cost of Atrioventricular Canal Defect: India vs. UAE
The cost of Atrioventricular Canal Defect repair varies substantially between India and the UAE, reflecting differences in operating costs, infrastructure models, and healthcare pricing structures — while both destinations maintain internationally accredited clinical standards. India offers a compelling value proposition, with complete AVCD repair available at 40–60% of the equivalent cost in the UAE, making it the preferred destination for families prioritizing affordability without compromising on surgical expertise or outcomes. The UAE, particularly Dubai and Abu Dhabi, offers premium hospital environments, seamless logistics for GCC-based families, and JCI/DHA-accredited facilities with multilingual medical teams. Cost estimates below are all-inclusive of the primary hospital admission, surgery, bypass perfusion charges, PCICU stay, ward stay, standard postoperative medications, and routine inpatient investigations.
| Destination | Estimated Cost (USD) | Key Advantage |
|---|---|---|
| India | $5,000 – $9,000 | ~61% less than the UAE |
| UAE (Dubai/Abu Dhabi) | $14,000 – $22,000 | Premium care, JCI/DHA accredited |

• Annual: Lifelong cardiology follow-up required; approximately 5–10% of patients require reoperation within 10 years, most commonly for progressive left AV valve regurgitation.
Risks & Considerations
Atrioventricular Canal Defect repair is a high-complexity congenital cardiac procedure and carries meaningful perioperative risks that families must understand transparently before proceeding. Overall operative mortality in high-volume specialized centers ranges from 2–5% for complete AVCD repair; partial AVCD repair carries lower mortality of <1%. The most significant and most common cause of reoperation is residual or recurrent left atrioventricular (neo-mitral) valve regurgitation, occurring in 5–10% of patients within 10 years of repair and potentially requiring mitral valve re-repair or, rarely, mechanical valve replacement. Postoperative pulmonary hypertensive crises represent a critical perioperative risk, particularly in children repaired after 6 months of age or with elevated preoperative pulmonary vascular resistance; management with inhaled nitric oxide, high-frequency ventilation, and intravenous sildenafil has substantially reduced mortality from this complication. Transient complete heart block (requiring temporary epicardial pacing) occurs in approximately 5–10% of patients due to proximity of the AV node and bundle of His to the patch suture lines; permanent complete heart block necessitating pacemaker implantation occurs in fewer than 2% of cases at experienced centers. Residual ventricular septal defect (VSD) of hemodynamic significance requiring re-intervention occurs in approximately 2–4% of cases. Low cardiac output syndrome in the immediate postoperative period is managed with inotropic support (milrinone, epinephrine) and is expected to resolve within 48–72 hours in most cases. Infection risks include mediastinitis (deep sternal wound infection, <1%), pneumonia, and urinary tract infection, all managed with perioperative antibiotic prophylaxis protocols. Neurological complications, including stroke or neurodevelopmental impairment attributable to cardiopulmonary bypass, are reported in <1% of cases at modern centers using refined CPB management, pH-stat strategy, and NIRS monitoring. Chylothorax (lymphatic leak causing milky pleural effusion) occurs in approximately 3–5% of cases and is typically managed with medium-chain triglyceride diet, octreotide infusion, and rarely thoracic duct ligation. Families should also understand that children with trisomy 21 who undergo complete AVCD repair have outcomes statistically equivalent to chromosomally normal children in terms of operative survival, though neurodevelopmental follow-up is separately required.

Frequently Asked Questions — Atrioventricular Canal Defect
In India, the total cost of complete Atrioventricular Canal Defect (AVCD) repair at a JCI- or NABH-accredited hospital typically ranges from USD 5,000 to USD 9,000. This estimate is all-inclusive and covers the cardiac surgery itself, cardiopulmonary bypass perfusion charges, the Pediatric Cardiac Intensive Care Unit (PCICU) stay of 3–5 days, the step-down ward stay of 7–11 days, standard postoperative medications (including inhaled nitric oxide charges, milrinone infusion, diuretics, and ACE inhibitors), and routine inpatient investigations such as echocardiography, ECG, and chest X-rays. In the UAE — specifically Dubai and Abu Dhabi — the equivalent procedure at a JCI/DHA-accredited hospital is estimated to cost between USD 14,000 and USD 22,000, reflecting the higher operating cost environment and premium hospital infrastructure. India is therefore approximately 40–60% less expensive than the UAE for this procedure. Neither estimate includes international airfare, accommodation for accompanying family members during the post-discharge observation period, or additional interventions that may be required for complex cases (such as pulmonary artery banding prior to complete repair, or permanent pacemaker implantation). GAF Healthcare provides a detailed, personalized cost estimate after review of the child's medical records, as complexity factors such as Rastelli valve type, degree of pulmonary hypertension, and associated cardiac lesions can influence the final cost.
International air travel should not be attempted before a minimum of 4 to 6 weeks from the date of surgery for Atrioventricular Canal Defect repair. This timeline is not arbitrary — it reflects several specific medical safety thresholds that must be met before a pediatric cardiac patient can safely tolerate the physiological stresses of flight, including cabin altitude pressurization (equivalent to approximately 6,000–8,000 feet above sea level), limited access to emergency medical care, and prolonged immobility. Before a fit-to-fly clearance is issued, the treating pediatric cardiologist and surgeon must confirm: (1) sternal bone healing is adequate, assessed clinically and radiographically; (2) a repeat echocardiogram shows a stable repair with no significant residual ventricular septal defect, no significant left atrioventricular valve regurgitation, and no pericardial or pleural effusion; (3) oxygen saturation at rest is acceptable without supplemental oxygen; (4) the child is tolerating full oral feeds and has demonstrated adequate weight gain; and (5) all cardiac medications are stable, with no recent changes requiring close monitoring. Patients who developed complications such as postoperative pulmonary hypertension, chylothorax, or transient complete heart block may require a longer stay of 6–8 weeks or more. GAF Healthcare's case manager tracks all follow-up appointments during the post-discharge period and ensures the family receives the formal fit-to-fly letter from the treating team before departure arrangements are confirmed.
At high-volume pediatric cardiac centers in India and the UAE — the types of centers to which GAF Healthcare refers patients — the operative survival rate for complete Atrioventricular Canal Defect (AVCD) repair is 92–96%, meaning that 92 to 96 out of every 100 children undergoing the procedure survive the surgical episode and the immediate postoperative period. Partial AVCD repair carries an even lower operative risk, with survival rates exceeding 98–99% at experienced centers. These figures are consistent with outcomes published in the Society of Thoracic Surgeons (STS) Congenital Heart Surgery Database and peer-reviewed literature from leading international pediatric cardiac programs. Success rates are most strongly influenced by three factors: (1) the volume of congenital cardiac surgery performed at the center — centers performing more than 150–200 congenital open-heart operations annually consistently demonstrate superior outcomes; (2) preoperative pulmonary vascular resistance — children repaired before the development of significant pulmonary hypertension (PVR index <4 Wood Units·m²) have substantially better outcomes than those repaired later; and (3) the degree of left atrioventricular valve regurgitation at the end of repair, assessed by intraoperative transesophageal echocardiography. Long-term freedom from reoperation (most commonly for recurrent left AV valve regurgitation) is approximately 85–90% at 10 years. Children with trisomy 21 undergoing complete AVCD repair achieve operative survival rates equivalent to chromosomally normal children, a finding consistently reproduced across multiple international series.
Why Plan Your Treatment Through Gaf Healthcare?
GAF Healthcare provides comprehensive non-medical coordination for international families traveling for Atrioventricular Canal Defect repair, ensuring that logistical complexity does not add to the stress of a pediatric cardiac surgery journey.
VISA ASSISTANCE — INDIA: India's e-Medical Visa is the appropriate category for treatment travel and allows for two companion (attendant) visas for accompanying family members. GAF Healthcare's visa team prepares and submits the full application package — including the hospital invitation letter, treatment plan summary, and supporting documents — targeting approval within 48–72 business hours. The e-Medical Visa allows stays of up to 60 days with multiple-entry, which is sufficient to cover the required 4–6 week post-operative observation period.
VISA ASSISTANCE — UAE: For most international patients, the UAE offers visa-on-arrival (30 days) or visa-free entry for nationals of over 50 countries. For patients from countries requiring advance visa processing, GAF Healthcare coordinates medical visa or visit visa applications through the partner hospital's International Patient Services department, in compliance with Dubai Health Authority (DHA) and Abu Dhabi Department of Health (DOH) regulations. Medical visa extensions are available for patients requiring a longer stay.
AIRPORT TRANSFERS: Dedicated private vehicle transfers are arranged for arrival and departure, with vehicles appropriately equipped to accommodate medically fragile infants and their families with medical equipment if required (portable oxygen, suction).
ACCOMMODATION FOR ATTENDANTS: For the in-hospital period, GAF Healthcare arranges in-hospital attendant accommodation (parent room within pediatric wards) where available. For the post-discharge observation period (typically 2–4 weeks), GAF Healthcare partners with serviced apartments and guesthouses within 2–5 kilometers of the treating hospital, selected for proximity, hygiene standards, and cooking facilities — critical for families managing infant nutrition post-operatively. A range of budget-to-mid-range options is available for India, and mid-to-premium serviced apartments are arranged in Dubai and Abu Dhabi.
DEDICATED MEDICAL COORDINATOR AND TRANSLATORS: Each patient family is assigned a dedicated GAF Healthcare case manager who serves as a single point of contact from the initial consultation through the post-discharge follow-up period. For non-English speaking families, certified medical interpreters are arranged for key consultations — including pre-operative consent, surgeon briefings, and discharge instruction sessions. Language support commonly available includes Arabic, French, Russian, Swahili, Bengali, and Amharic.
TELEMEDICINE FOLLOW-UP COORDINATION: After the family returns home, GAF Healthcare coordinates post-operative teleconsultation sessions between the treating surgical team and the family's local cardiologist, facilitating the transmission of echocardiography reports, discharge summaries, and medication plans across borders, ensuring continuity of care in the critical months following repair.
