Abstract

The objective of this study was to assess the fate at long term of mild-to-moderate functional tricuspid regurgitation (TR) left untreated at the time of mitral valve repair in patients with dilated cardiomyopathy. We selected from our prospective hospital database 84 patients (age, 64 ± 9.6 years; ejection fraction, 0.31 ± 0.064) who underwent mitral repair for secondary mitral regurgitation in whom concomitant mild-to-moderate TR (nonlinear scale 1 to 4+) was left untreated. Tricuspid regurgitation was classified as mild in 61 patients (72.6%) and moderate in 23 patients (27.3%). Annular dilatation itself was not systematically measured and was not used as a trigger for tricuspid annuloplasty. Most of the patients were in New York Heart Association functional class III or IV (56 of 84; 66.7%). At a median follow-up of 7.3 years (interquartile range, 4.5 to 9.3), 17 patients (20.2%) had moderate-to-severe TR and 21 patients (25%) showed a progression of at least two grades of their untreated preoperative TR. Freedom from moderate-to-severe TR or from progression of at least two grades of the baseline TR was 77% ± 5% at 5 years and 56.7% ± 8.4% at 10 years. Multivariate analysis identified preoperative right ventricular dysfunc...Continue Reading

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
