TAVI (Transcatheter Aortic Valve Implantation): Indications, Procedure, Recovery, and Cost in India

Transcatheter Aortic Valve Implantation (TAVI), also known as Transcatheter Aortic Valve Replacement (TAVR), is a minimally invasive percutaneous procedure designed to replace a severely calcified, stenotic aortic valve without sternotomy (open-heart surgery) or cardiopulmonary bypass. This clinical guide outlines patient selection criteria, procedural pathways, prosthetic valve systems, recovery expectations, and treatment costs in India based on international cardiology guidelines.

Clinical Signs and Symptoms of Severe Aortic Stenosis

Aortic stenosis (AS) typically exhibits a prolonged latent period during which progressive obstruction is offset by compensatory left ventricular hypertrophy. However, once the aortic valve area decreases below 1.0 cm² (or indexed valve area <0.6 cm²/m²) with mean transvalvular gradients >40 mmHg, hemodynamic decompensation occurs, precipitating the classic clinical triad:

  • Exertional Dyspnea (Heart Failure Symptoms): Shortness of breath during minor exertion, progressing to orthopnea and paroxysmal nocturnal dyspnea due to elevated left ventricular end-diastolic pressure and pulmonary venous congestion (average survival without intervention: ~2 years).
  • Angina Pectoris (Exertional Chest Pain): Substernal chest tightness precipitated by exertion, caused by severe myocardial supply-demand mismatch in hypertrophied myocardium, even in the absence of obstructive coronary disease (average survival without intervention: ~3 years).
  • Exertional Syncope or Presyncope: Sudden dizziness, lightheadedness, or loss of consciousness during exercise, resulting from fixed cardiac output in the setting of exercise-induced peripheral vasodilation or transient ventricular arrhythmias (average survival without intervention: ~3 years).
  • Fatigue and Exercise Intolerance: Profound reduction in stamina and functional capacity, often underreported by elderly patients who subconsciously adapt by restricting their daily activities.
  • Harsh Systolic Ejection Murmur: A crescendo-decrescendo systolic murmur loudest at the right second intercostal space, radiating to the carotid arteries, frequently accompanied by a diminished or delayed carotid pulse (pulsus parvus et tardus) and a soft second heart sound (absent or single A2).

Emergency Warning: The onset of syncope, angina, or resting breathlessness in patients with known severe aortic stenosis represents a medical emergency with high risk of sudden cardiac death. Urgent structural heart or cardiothoracic evaluation is imperative.
