Tricuspid valve surgery presents significant challenges in diagnosis and treatment due to its low incidence and complex relationship with the left heart. Surgical outcomes are often dictated by left-side valve repair, not tricuspid valve intervention.

Area of Science:

  • Cardiovascular Surgery
  • Cardiac Valve Disease

Background:

  • The tricuspid valve poses diagnostic and therapeutic challenges due to its low incidence, low-pressure system function, and interdependence with right ventricular function and left-sided lesions.
  • Tricuspid valve pathology is often secondary to left-sided heart disease, complicating treatment decisions.

Purpose of the Study:

  • To review surgical experience with the tricuspid valve, analyzing incidence, pathology, diagnosis, influence of left-side lesions, and surgical techniques.
  • To elucidate the current status and challenges associated with tricuspid valve surgery.

Main Methods:

  • Retrospective review of 1298 valvular patients operated between July 1988 and August 1993.
  • Analysis categorized by incidence, pathology (rheumatic vs. functional), diagnosis (echocardiography), influence of left-side lesions, and surgical techniques (annuloplasty).

Main Results:

  • Tricuspid valve surgery was required in 23.6% of valvular patients; 27.7% of rheumatic heart disease patients had tricuspid involvement.
  • Organic rheumatic disease and functional regurgitation were equally prevalent (50.6% vs. 49.4%), with 45.3% of organic cases showing annular dilation.
  • Preoperative diagnosis of organic tricuspid lesions was only 41.7% accurate; postoperative outcomes were primarily linked to mitral valve surgery results.

Conclusions:

  • Tricuspid valve surgery remains complex, with diagnosis and treatment influenced by its low-pressure environment and association with left-sided valve disease.
  • Annuloplasty procedures for tricuspid valve disease can result in residual stenosis, particularly in organic lesions, and overall surgical success is often dependent on concurrent mitral valve repair outcomes.
