Propionibacterium acnes, a constituent of the human cutaneous flora, infected both the native mitral valve and a Carpentier mitral annuloplasty ring in an adolescent patient. In the case of culture negative endocarditis, the incubation period of blood cultures should be prolonged to identify this pathogen.

We report a case of supra-annular mitral valve replacement for a patient with prosthetic ring endocarditis that developed late after undergoing undersized mitral annuloplasty (UMAP). A 58year-old man had undergone left ventriculoplasty and UMAP with a 26-mm semi-rigid full ring for dilated cardiomyopathy and functional mitral regurgitation. The mitral valve had progressively stenosed and he dev...

Study objectives: Prospective evaluation of a selectively flexible annuloplasty ring was under¬ taken to assess its safety and efficacy. Patients: Between December 1992 and November 1996, 190 patients with mitral regurgitation underwent mitral valve repair using an annuloplasty ring (Carpentier-Edwards Physio; BaxterEdwards CVS Laboratories; Irvine, Calif). Ninety-four were in New York Heart As...

Introduction Mitral regurgitation (MR) is associated with an increase in mortality in patients with left ventricular dysfunction1, and more recently has also been associated with increased cardiac events even in asymptomatic patients2. The combination of a desire to improve survival as well as quality of life in symptomatic subjects accounts for the approximately 100,000 mitral valve operations...

In cases of old myocardial infarction, the presence of mitral valve regurgitation is one of the predicting factors of long-term prognosis. The mechanism of ischemic mitral regurgitation consists of mitral annular dilatation, left ventricular (LV) dilatation followed by tethering of the mitral valve, etc. Since long-term prognosis of the patients in whom the degree of mitral valve regurgitation ...

Background. Unoperated severe tricuspid regurgitation (TR) leads to the right ventricle (RV) failure. We wanted to determine if there was near-term postoperative progression of noncorrected mild to moderate functional TR in patients who underwent mitral valve surgery for chronic significant mitral regurgitation (MR) and if RV size and function were affected. Methods and Results. We compared two...

Mitral regurgitation (MR) is a frequent complication of end-stage cardiomyopathy. Historically, these patients were managed either medically or with mitral valve replacement, both associated with poor outcomes. We studied 150 patients with cardiomyopathy and severe MR who were managed with mitral reconstruction. One hundred fifty patients with 4+ MR, left ventricular ejection fractions of 8%-24...

BACKGROUND Ischemic mitral regurgitation often complicates severe ischemic heart disease and adversely affects the prognosis in these patients. There is wide variation in the clinical spectrum of ischemic mitral regurgitation due to varying location and chronicity of ischemia and anomalies in annular and ventricular remodeling. As a result, there is lack of consensus in treating these patients....

OBJECTIVE To examine the mid-term results of patients on whom a coronary revascularization as well as a mitral ring and suture annuloplasty have been performed due to coronary artery disease (CAD) and ischaemic mitral regurgitation (IMR). METHODOLOGY Totally 73 patients on whom a revascularization and a mitral valve repair due to CAD and IMR had been performed in our clinic between 2000-2008 ...
