A new reconstructive operation for correction of mitral and tricuspid insufficiency

Long-Term Outcomes of Mitral Valve Repair with the Duran Flexible Ring

“…The flexible ring, developed by Duran and associates, 2 reduces the annulus size but allows for it to continuously change during the cardiac cycle 3 in contrast to the rigid ring developed by Carpentier and colleagues. 4 David and associates demonstrated that a flexible annuloplasty ring results in better left ventricular systolic function than a rigid annuloplasty ring two to three months after mitral valve reconstruction. 5 Similar results were reported by Okada and associates six months after MV repair with a flexible ring.…”

Prophylactic tricuspid annuloplasty in patients with dilated tricuspid annulus undergoing mitral valve surgery

“…5 Unlike TR grade, tricuspid annular dilatation is a relatively objective measurement that can be assessed independently of the patient's hemodynamic status. 13 Although significant reductions in grade and progression of functional TR after cardiac surgery have been observed with TV annuloplasty, 5 the benefit of prophylactic TV annuloplasty remains controversial. We therefore designed this study to test the hypothesis that concomitant TV annuloplasty in patients with tricuspid annulus dilatation (!40 mm) prevents TR progression after mitral valve surgery and to evaluate whether this is associated with improved right ventricular (RV) remodeling or a functional benefit.…”

Assessment of Mitral Annulus (P3 Segment) Asymmetric Deformity in Myocardial Infarction with Ischemic Regurgitation by Real Time Three‐Dimensional Echocardiography

“…Anatomically, the two mitral leaflets are basally attached to a fibromuscular ring in the fibrous skeleton of the heart, known as the annulus fibrosus. 19,20 The fibrous trigones, as major components of the annulus fibrosus, sit adjacent to the commissures. The more prominent right fibrous trigone (or central fibrous body) is equidistant from the tricuspid, mitral, and aortic valves, whereas the left fibrous trigone is seated between the mitral and aortic valve, towards the peripheral and most posterior portion of the fibrous skeleton.…”
