Cardiac surgery abroad: UK patient guide to heart surgery overseas (2026)

Cardiac surgery abroad is a growing option for UK patients facing long NHS waiting lists for non-emergency heart procedures, or who need surgery that is not available on the NHS at all. India and Thailand have internationally accredited cardiac centres that handle significant volumes of UK and international patients each year. This guide covers what is available, what it costs, and how to evaluate safety.

Cardiac procedures available abroad for UK patients

• Coronary artery bypass grafting (CABG): The most commonly sought cardiac procedure abroad for UK patients. NHS waiting times for elective CABG now exceed 12–18 months in many regions.
• Heart valve replacement or repair: Aortic and mitral valve procedures, including minimally invasive approaches.
• TAVR/TAVI: Transcatheter aortic valve replacement — a minimally invasive valve procedure for patients not suitable for open-heart surgery.
• Coronary angioplasty and stenting (PCI): Shorter procedure with faster recovery. Available in most destinations.
• Electrophysiology procedures: Ablation for AF, SVT and other arrhythmias.

Cost comparison: India, Thailand vs UK private

At internationally accredited cardiac centres:

• CABG (triple bypass): £12,000–£20,000 in India; £18,000–£28,000 in Thailand; £25,000–£45,000 at UK private hospitals.
• Aortic valve replacement (surgical): £14,000–£22,000 in India; £20,000–£30,000 in Thailand; £30,000–£55,000 in UK private.
• TAVR/TAVI: £18,000–£28,000 in India; £22,000–£35,000 in Thailand; £35,000–£60,000 in UK private.

These are all-inclusive prices for the procedure, hospital stay (typically 5–10 days), and follow-up during the local stay. Budget separately for flights (£400–£800 return to India/Thailand from UK) and extended local stay for recovery (additional 1–2 weeks recommended).

Best destinations for cardiac surgery abroad

India (Chennai, Gurgaon, Mumbai, Hyderabad): India has the highest volume of international cardiac surgery in the world. Centres such as Apollo Hospitals Chennai, Fortis Escorts Heart Institute (Delhi), Narayana Health (Bangalore), and Medanta (Gurgaon) are JCI-accredited, publish outcome data, and have dedicated international patient departments with UK coordinators. Cardiac surgery volume at these centres is extremely high — which is a major quality indicator. Outcomes data from Apollo and Narayana is published and comparable to leading US and UK centres.

Thailand (Bangkok): Bumrungrad International Hospital and Bangkok Heart Hospital are the primary cardiac destinations. JCI-accredited, English-speaking, with JCIA cardiac standards. Cost is higher than India but the facility experience is comparable to UK private hospitals.

Turkey (Istanbul): A smaller but growing cardiac destination. Florence Nightingale Hospital and Acibadem network hospitals handle international cardiac patients. More practical for shorter procedures (PCI, ablation) than major open-heart surgery.

The most important quality indicator: surgical volume

For cardiac surgery, volume is the single most evidence-based quality predictor. Published data consistently shows lower mortality and complication rates at centres performing high volumes of CABG (above 400 per year) and valve procedures (above 200 per year) compared to lower-volume centres. Ask any cardiac centre for their annual procedure volume before committing. India's top cardiac centres each perform thousands of cases per year — this is a genuine quality advantage.

How to safely pursue cardiac surgery abroad

• Get a second opinion from a UK cardiologist before travelling. Your diagnosis, recommended procedure, and urgency must be confirmed. Elective cardiac surgery abroad is appropriate; emergency cardiac surgery abroad is not — if you are in crisis, treat locally.
• Share your full cardiac workup with the overseas centre before you travel — ECG, echocardiogram, angiogram results, medication list, and GP letter. Any reputable centre will want this for a pre-assessment.
• Book with a JCI-accredited centre. For cardiac specifically, check for JCIA-accreditation (the cardiac-specific designation).
• Identify a UK cardiologist for follow-up before you travel. Post-cardiac surgery care is lifelong — you need a UK cardiologist who will accept your case.
• Get specialist medical travel insurance that covers cardiac surgical complications, repatriation, and extended stay.

NHS position on treatment abroad

The NHS will treat cardiac emergencies on return to the UK free of charge. Routine follow-up post-cardiac surgery (medications, echocardiograms, cardiac rehabilitation) should be available through your NHS GP and cardiologist. However, elective revision of cardiac surgery performed abroad is likely to require NHS waiting lists or UK private fees — ensure the overseas centre has a clear protocol for complications and revision.

Is cardiac surgery abroad safe?

At JCI-accredited cardiac centres with high surgical volumes, published outcome data, and board-certified cardiac surgeons — yes, the risk profile is comparable to UK private centres. The key is that cardiac surgery is never risk-free anywhere; the question is whether the specific centre can demonstrate outcomes that meet international benchmarks. Ask for the centre's 30-day mortality rate for your specific procedure, and compare it to NHS outcomes data. If the centre cannot provide this, look elsewhere.
