Heart Valve Replacement (Aortic/Mitral)

Candidates include patients with severe symptomatic aortic stenosis (valve area <1.0 cm², mean gradient >40 mmHg), severe aortic or mitral regurgitation with LV dysfunction or symptoms, rheumatic valve disease with heavy calcification precluding repair, failed prior valve repair, prosthetic valve dysfunction, and valve endocarditis with extensive tissue destruction. A multidisciplinary Heart Team determines the optimal approach.

Mechanical valves (pyrolytic carbon) last 25-30+ years but require lifelong warfarin anticoagulation with regular INR monitoring. Bioprosthetic valves (bovine pericardial or porcine tissue) last 10-20 years and only require anticoagulation for 3-6 months, but may eventually need re-intervention. Generally, mechanical valves are preferred for patients under 50 (aortic) or 65 (mitral), while bioprosthetic valves suit older patients or those with anticoagulation contraindications.

Recovery progresses through phases: ICU for 1-3 days with continuous monitoring, step-down ward for 4-5 days with progressive mobilization, early home recovery for 6 weeks (sternal precautions, no lifting >10 lbs, progressive walking), and full recovery at 8-12 weeks. Most patients return to sedentary work at 4-6 weeks and physical labor at 8-12 weeks.

For uncomplicated isolated valve replacement, a minimum of 4-6 weeks before flying is recommended. Multi-valve or combined procedures require 6-8 weeks. Mechanical valve patients must have INR stable in therapeutic range for at least 2 weeks. Your surgeon will typically assess fitness-to-fly criteria including the ability to walk 100 meters without dyspnea, climb one flight of stairs, maintain adequate oxygen saturation, and demonstrate stable blood counts. Always follow your physician's specific guidance.

Thailand's all-inclusive valve replacement packages at JCI-accredited hospitals range from $15,000-$35,000 (average ~$17,000), compared to $50,000-$160,000 in the United States (average ~$105,000). The prosthetic valve itself is included in Thailand's package price — a component billed separately at $5,000-$50,000 in the US. Even including travel and 4-5 week accommodation costs of $3,000-$6,000, net savings are typically approximately 65-70% depending on individual circumstances.

It depends on valve type. Mechanical valves require lifelong warfarin anticoagulation with INR targets determined by your surgeon based on valve type and position, plus low-dose aspirin. Bioprosthetic valves require only aspirin long-term, with optional short-term warfarin for 3-6 months. Certain newer mechanical valve models may allow reduced anticoagulation targets based on clinical evidence. Your cardiac team will determine the appropriate anticoagulation regimen for your specific situation. All prosthetic valve patients require lifelong endocarditis prophylaxis before dental procedures.

TAVR (Transcatheter Aortic Valve Replacement) is a minimally invasive alternative to open surgical AVR, delivering a new valve via catheter through the femoral artery. It is preferred for high-risk or elderly patients (STS score >8%) and appropriate for intermediate-risk patients. Low-risk patients under 65 generally benefit more from surgical AVR due to proven long-term durability. As of 2025, TAVR is available at Bumrungrad, MedPark, Samitivej, Vejthani, and Praram 9 in Thailand. Confirm current availability with your hospital coordinator.

Plan for a minimum 4-5 week stay: 3-5 days for pre-operative diagnostics (confirmatory TTE/TEE, coronary angiography, CT sizing, surgeon meeting), 7-10 days for surgery and hospital stay including ICU and INR stabilization, and 14-21 days for local recovery with daily nursing visits, INR titration, and wound checks at a hotel or serviced apartment before receiving fitness-to-fly clearance.

For low-risk isolated AVR, 30-day mortality is 1-2%. Mechanical valves have >95% freedom from structural failure at 25 years. Bioprosthetic valves show 95%+ freedom from structural deterioration at 5 years, 70-85% at 10 years, and 50-70% at 15 years. Failed bioprosthetic valves can now be treated with valve-in-valve TAVR (3-5% mortality), avoiding redo sternotomy in high-risk patients.

Preparation includes transferring medical records with echocardiogram and coronary angiography results, completing a virtual consultation with your Thai cardiac surgical team, obtaining mandatory dental clearance at least 2 weeks before surgery, stopping anticoagulants per the prescribed timeline (warfarin 5 days, DOACs 2-3 days), arranging travel insurance with cardiac complication coverage, and planning your 4-5 week stay including post-discharge accommodation near the hospital.

Mechanical valve patients require lifelong warfarin (with regular INR monitoring) plus low-dose aspirin as prescribed by your cardiac team. Bioprosthetic valve patients typically need low-dose aspirin indefinitely. Additional medications depend on your condition: beta-blockers for AF or LV dysfunction, ACE inhibitors for heart failure or hypertension, and statins for concurrent atherosclerotic disease. Your surgeon will determine specific dosages based on your individual needs. All patients require lifelong endocarditis prophylaxis antibiotics before dental procedures.
