Aortic valve repair — the surgical reconstruction of a diseased aortic valve while preserving the native leaflet tissue — is one of the most technically demanding and specialized operations in cardiac surgery, offered at only a limited number of truly expert centers worldwide. Unlike aortic valve replacement (which substitutes the native valve with a mechanical or biological prosthesis), repair preserves the patient's own aortic valve leaflets, avoiding the need for lifelong anticoagulation (with mechanical replacement) and the progressive deterioration over 10–15 years (with biological replacement) — outcomes that are particularly important for young patients with decades of life ahead.

The aortic valve has three leaflets (cusps) that open during systole (when the left ventricle pumps blood into the aorta) and close during diastole (preventing backflow into the ventricle). Aortic valve disease suitable for repair typically involves aortic regurgitation (leakage) from: aortic root dilation stretching and separating the leaflets (without leaflet destruction — the most favorable anatomy for repair); bicuspid aortic valve (two leaflets fused into one — congenital abnormality causing both stenosis and regurgitation, with repair possible in selected cases with good leaflet quality); and pure aortic regurgitation from leaflet prolapse without significant calcification.

The David procedure (valve-sparing aortic root replacement, Type I) — replacing the aortic root with a Dacron tube while reimplanting and preserving the native aortic valve within the new root — is the definitive operation for aortic root aneurysm with intact leaflets. It avoids the need for the composite mechanical valve-graft of the Bentall procedure, preserving the native valve and avoiding lifelong anticoagulation. Pioneered by Tirone David at the University of Toronto, this procedure requires very high surgical expertise but provides outstanding long-term results in centers with sufficient volume.

India's specialized aortic centers — Apollo Hospitals Chennai, Medanta – The Medicity, and AIIMS New Delhi — offer aortic valve repair at costs of $6,500–$11,000 — dramatically below the $35,000–$60,000 charged in leading US aortic surgery centers.

What is Aortic Valve Repair and When Is It Possible?

Aortic valve repair encompasses several distinct surgical strategies:

Valve-Sparing Aortic Root Replacement (David procedure): The most important "aortic valve repair" — performed for aortic root aneurysm with normal or near-normal aortic leaflets. The aortic root is completely replaced with a Dacron tube, but the native aortic valve leaflets are preserved and reimplanted within the new Dacron root at anatomically correct positions. The David type I (reimplantation technique) — favored for superior long-term durability — suspends the valve annulus within the Dacron tube at a fixed, reduced diameter, preventing further annular dilation and stabilizing the repair. The David procedure provides 10-year freedom from valve dysfunction of 85–90% in expert hands.

Bicuspid Aortic Valve Repair: For patients with a bicuspid aortic valve (BAV) causing primarily aortic regurgitation with good leaflet quality (no or minimal calcification, adequate leaflet tissue), repair involves: resection of the fused raphe (the area of leaflet fusion), leaflet augmentation with pericardium, and annuloplasty (external aortic annuloplasty with a ring or suture reduction of the aortic annulus to correct dilation). Bicuspid valve repair has more variable durability than degenerative mitral repair; 10-year freedom from reoperation is 70–80% at experienced centers.

Isolated Aortic Leaflet Repair: For pure prolapsing aortic regurgitation (one leaflet prolapsing due to leaflet fenestration or free edge elongation), triangular resection of the redundant leaflet with suture reduction of the free edge restores coaptation and eliminates regurgitation. Results are best for unicuspid leaflet prolapse; more variable for commissural tears.

Who is a Candidate for Aortic Valve Repair?

The David procedure (valve-sparing root replacement) is ideal for: young patients (under 60) with aortic root aneurysm (above 5 cm, or 4.5 cm in Marfan syndrome) who have morphologically normal or minimally abnormal aortic leaflets (all three leaflets present, no calcification, no significant fenestrations, adequate leaflet height and pliability). These patients would otherwise require the Bentall procedure with a mechanical composite graft and lifelong anticoagulation.

Isolated bicuspid valve repair is considered for younger patients (under 45–50) with dominant aortic regurgitation from a bicuspid valve with good leaflet quality. The patient must understand that repair durability is lower than tricuspid valve repair, and reoperation in 10–15 years is more likely than with replacement.

The critical requirement: an experienced surgeon who performs valve-sparing procedures regularly (above 20–30 David procedures per year) — durability of the repair is directly related to the surgeon's technical proficiency and volume. At surgeons performing fewer than 5–10 cases per year, reoperation rates and early valve dysfunction are significantly higher.

How is Aortic Valve Repair Performed?

The David procedure (valve-sparing aortic root replacement):

Under general anesthesia with cardiopulmonary bypass, the ascending aorta and aortic root are exposed via median sternotomy. Deep hypothermia (18–22°C) is used to allow temporary circulatory arrest for arch reconstruction if the aortic arch is also involved. After cardiac arrest with cardioplegia:

The aneurysmal aortic root is completely resected — the aortic leaflets are carefully preserved on a small margin of aortic wall. The native aortic valve is assessed for leaflet quality; any leaflet pathology is corrected (free edge stabilization, fenestration repair).

A Dacron tube graft of appropriate diameter is chosen. The aortic annulus is sized and reduced if necessary. The native aortic valve — all three leaflets preserved on their small cuff of tissue — is reimplanted within the Dacron tube at anatomically correct positions, with the leaflets suspended at appropriate heights to ensure full coaptation.

The coronary arteries (left and right) are reimplanted as buttons into the Dacron tube (exactly as in the Bentall). The distal end of the tube is anastomosed to the remaining ascending aorta or aortic arch.

Intraoperative TEE assesses the reconstructed valve for residual regurgitation, optimal leaflet coaptation, and absence of stenosis. The geometry of the repair is refined if any deficiency is identified.

Procedure Steps

1. Pre-operative: CT aortography (aortic root and ascending aorta dimensions; coronary ostia heights; aortic valve leaflet anatomy); echocardiography (degree of AR, LV function, leaflet quality); MRI if available for 3D leaflet assessment.
2. Anesthesia: general anesthesia; TEE; bilateral radial arterial lines; central venous catheter.
3. Cardiopulmonary bypass with deep hypothermia (18–22°C) if arch repair needed; otherwise moderate hypothermia (25–28°C).
4. Cardiac arrest: cold blood cardioplegia; aortic cross-clamp.
5. Root excision: aortic root excised; valve leaflets preserved on a 3–5 mm cuff of aortic sinus tissue; coronary arteries mobilized as buttons.
6. Leaflet preparation: any leaflet prolapse, fenestration, or free edge elongation corrected; prolapsing free edges plicated with Gore-Tex suture.
7. Dacron tube preparation: appropriate-diameter tube selected; four double-armed 2-0 sutures placed at the nadir of each inter-leaflet triangle and each commissure.
8. Valve reimplantation: native valve leaflets reimplanted within the Dacron tube; each commissure suspended at correct height; annular sutures tied.
9. Coronary reimplantation: left and right coronary buttons sutured to openings in Dacron tube.
10. Distal anastomosis: tube anastomosed to ascending aorta.
11. De-airing and rewarming; cross-clamp released; intraoperative TEE confirms AR absent or trace, no stenosis.
12. Weaning from bypass; hemostasis; sternal closure.

Aortic valve repair (David procedure) packages in India include the Dacron tube graft, surgery, cardiopulmonary bypass, intraoperative TEE, ICU stay (2–3 days), ward stay (7–10 days), and post-operative echocardiography before discharge. Gaf Healthcare verifies the specific David procedure volume of recommended surgeons before making referrals.

Recovery & Follow-up

Recovery follows standard sternotomy-based open-heart surgery: ICU 2–3 days; ward 7–10 days; sternal healing 6–8 weeks; full activity at 10–12 weeks. No anticoagulation is required — aspirin alone suffices if sinus rhythm is maintained.

Annual echocardiography monitors the repaired valve for residual or recurrent aortic regurgitation. CT aortography at 3–5 years surveys the remaining aorta (particularly relevant for Marfan patients whose descending aorta may continue to dilate after successful root repair). Beta-blockers are continued for Marfan patients lifelong.

Recovery Tips

• No anticoagulation needed after successful David procedure — take aspirin 75–100 mg daily only.
• Marfan patients: continue beta-blockers (bisoprolol, atenolol) at target dose lifelong — reduces aortic wall stress.
• Annual echocardiogram — monitors aortic regurgitation grade and residual root dimensions.
• CT aortography at 3–5 years — monitors the remaining aorta and coronary button anastomoses.
• Carry an emergency card describing the David procedure, Dacron tube size, and surgeon details when travelling.
• Endocarditis prophylaxis before dental procedures — while the native leaflets are preserved, the Dacron conduit is a prosthetic material.

Risks & Complications

The David procedure carries a mortality of under 1–2% at high-volume experienced aortic surgery centers for elective cases. Specific risks: early aortic regurgitation recurrence (more than trace AR on post-operative TEE requiring return to bypass for revision — 2–5%); late valve dysfunction requiring reoperation (10–15% at 10 years); coronary button anastomosis pseudoaneurysm (rare — less than 1%); stroke (less than 1%); and the standard sternotomy risks. Results are directly related to the surgeon's specific David procedure volume.

Frequently Asked Questions

What is the David procedure?

The David procedure (valve-sparing aortic root replacement) replaces the aneurysmal aortic root with a Dacron tube while preserving the patient's native aortic valve leaflets — reimplanting them within the new root. It avoids the mechanical valve and lifelong anticoagulation of the Bentall procedure, providing excellent long-term valve function for appropriately selected patients.

Is aortic valve repair better than replacement?

For young patients with aortic root aneurysm and intact leaflets, repair (David procedure) is preferred over mechanical composite graft (Bentall) because it avoids lifelong anticoagulation. For calcific aortic stenosis in older patients, the valve leaflets are too diseased to repair and replacement (surgical or TAVR) is required.

How long does a repaired aortic valve last?

At expert centers, 85–90% of David procedure repairs are free from significant aortic regurgitation recurrence at 10 years. Bicuspid valve repairs have 70–80% freedom from reoperation at 10 years. Annual echocardiography monitors repair durability.
