BACKGROUND: Long-term echocardiographic data on quantitative assessment of tricuspid and mitral regurgitation after heart transplantation are scarce. METHODS AND RESULTS: From November 1992 to December 2008, the medical records for 201 patients (mean age, 42.8±12.4 years, 47 females) who underwent heart transplantation were reviewed. Quantitative assessment of mitral and tricuspid valve function was performed using transthoracic echocardiography through long-term follow-up. A total of 196 (97.5%) patients were evaluated with echocardiography for more than 6 months postoperatively. During a mean echocardiography follow-up duration of 89.9±54.3 months, 23 (11.4%) patients showed either tricuspid regurgitation (TR >mild; n=21, 10.4%) or mitral regurgitation (MR >mild; n=6, 3.0%); 4 (2.0%) patients experienced both significant TR and MR. Freedom from moderate-to-severe TR at 10 years was 85.5±5.1% and 93.4±2.2% for the standard and bicaval techniques, respectively (P=0.531). Freedom from moderate-to-severe MR at 10 years was 96.0±2.7% and 98.6±1.0%, respectively, for the 2 techniques (P=0.252). In multivariate analysis, older-age donor emerged as the only independent predictor of significant TR (hazard ratio 1.06, 95% confidence interval 1.01-1.12, P=0.012). CONCLUSIONS: The long-term results of atrioventricular function after heart transplantation in adults were excellent regardless of anastomotic technique. Older-age donor was significantly associated with the development of postoperative TR.
