Tricuspid valve surgery: 15-year experience.
Tricuspid valve surgery has been associated with a high operative mortality. This study reviewed 51 patients who underwent 53 tricuspid valve procedures between 1975 and 1989. Most patients (82%) had evidence of rheumatic heart disease. Twenty-six patients (51%) had 42 previous cardiac operations, most involving the mitral valve. Eighty-two percent of patients were New York Heart Association (NYHA) class III or IV preoperatively, and almost all patients had associated disease of other valves. The indication for operation was tricuspid regurgitation in 45 patients, infectious endocarditis in 4, and tricuspid stenosis in 2. The tricuspid abnormality was functional in 67% and organic in 33%. There were 32 tricuspid valve replacements, 20 annuloplasties, and 1 tricuspid valve excision. The hospital mortality rate was 11.8% (six patients). On statistical analysis, none of the perioperative variables were a significant risk factor for hospital mortality. Twenty-nine patients (51%) had postoperative complications. Postoperative functional status improved markedly with 80% in NYHA class I and 13% in class II. Long-term follow-up was attempted but was unsatisfactory in this transient, indigent population.
