Clinical and hemodynamic influences of prophylactic tricuspid annuloplasty in mechanical mitral valve replacement
Abstract
The aim of this study was to evaluate the long-term clinical and hemodynamic influences of prophylactic tricuspid annuloplasty (TAP) in patients with less-than-moderate tricuspid regurgitation (TR) who underwent mitral valve replacement (MVR). Between November 1994 and December 2010, 293 patients with less-than-moderate TR who underwent primary mechanical MVR were categorized into 2 groups: TAP (n = 151) or no TAP (n = 142). The median age was 51 years (quartile (Q)1-Q3, 43-59 years). The cause of valve pathology was rheumatic in 92.5% of patients (n = 271). The prevalence of preoperative atrial fibrillation was in 73.0%. Using propensity score matching based on demographic information, 91 TAP patients could be matched to 91 no TAP patients. Median follow-up duration was 107 months (Q1-Q3, 76-162 months). There was no early mortality in either group. Early morbidities, including heart block were not different between groups. Although overall survival and freedom from cardiac-related mortality did not differ between groups (P = .519 and P = .115, respectively), freedom from recurrence of moderate or higher TR grade were significantly higher in the TAP group (P = .043). In subgroup analyses, these group differences of TAP were es...Continue Reading

Atrial Filbrillation
Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.
Atrial Fibrillation
Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.
Arrhythmia
Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
