Tricuspid valve replacement: postoperative and long-term results

Summary

Tricuspid valve replacement in severely ill patients had high early mortality, with icterus being a key risk factor. Long-term survival favored mechanical prostheses over bioprostheses, especially after seven years.

Area of Science:

  • Cardiovascular Surgery
  • Cardiac Valve Repair & Replacement

Background:

  • Tricuspid valve disease often affects severely debilitated patients.
  • Surgical outcomes for tricuspid valve replacement (TVR) in this population require careful evaluation.

Purpose of the Study:

  • To analyze the outcomes of tricuspid valve replacement in a consecutive series of patients.
  • To identify risk factors for hospital mortality and long-term survival.
  • To compare the performance of different types of prosthetic valves.

Main Methods:

  • Retrospective review of 146 patients undergoing tricuspid valve replacement between 1967 and 1987.
  • Analysis of operative and hospital mortality, including risk factor identification.
  • Long-term follow-up to assess survival rates and compare prosthetic valve types.

Main Results:

  • High operative/hospital mortality (16.4%), with preoperative icterus as an independent predictor.
  • Long-term survival at 60 months was 74%, decreasing to 23.4% at 180 months.
  • Bioprostheses showed inferior long-term survival compared to mechanical valves, particularly after 7 years.

Conclusions:

  • Tricuspid valve replacement in severely ill patients carries significant early risks.
  • Preoperative icterus is a critical predictor of hospital mortality.
  • Mechanical tricuspid valve prostheses demonstrate superior long-term durability compared to bioprostheses.
