Summary

Valvular heart disease affects 3 million Indians, primarily due to rheumatic causes. Conserving the natural heart valve mechanism through repair or replacement with biological substitutes is the preferred treatment approach.

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Public Health

Background:

  • Rheumatic heart disease is the leading cause of valvular heart disease in India, affecting an estimated 3 million patients.
  • Mitral valve disease often necessitates valvotomy or repair, while aortic valve issues typically require replacement with biological substitutes.
  • Tricuspid valve repair is consistently achievable, offering a high success rate.

Purpose of the Study:

  • To review current treatment strategies for valvular heart disease in India.
  • To evaluate the efficacy of valve repair versus replacement with prosthetic or biological options.
  • To emphasize the long-term benefits of conserving the natural heart valve mechanism.

Main Methods:

  • Review of clinical experience and outcomes over three decades.
  • Analysis of treatment approaches for mitral, aortic, and tricuspid valve diseases.
  • Comparison of natural valve conservation versus prosthetic valve implantation.

Main Results:

  • Mitral valve conservation via valvotomy or repair is highly effective.
  • Aortic valve repair is challenging; biological substitutes (autograft, homograft) are preferred over prosthetic valves.
  • Tricuspid valve repair is successful in all cases.
  • Prosthetic valves provide durability but carry increased patient risks.

Conclusions:

  • Conservation of the natural heart valve mechanism is the optimal strategy for valvular heart disease.
  • Prioritizing repair and biological substitution offers better long-term outcomes compared to prosthetic valves.
  • Addressing rheumatic heart disease remains critical in India's cardiovascular health landscape.
