Two years previously, a 73-year-old man with mitral regurgitation underwent mitral annuloplasty and left atrial appendage (LAA) exclusion by suturing the orifice from the endocardium. However, the mitral regurgitation became exacerbated, and the left atrium enlarged rapidly over a 6-month period. Computed tomography showed a heterogenic mass in the LAA, and coronary angiography revealed a coron...

In the current scientific literature, particular attention is dedicated to the study of the mitral valve and to comprehension of the mechanisms that lead to its normal function, as well as those that trigger possible pathological conditions. One of the adopted approaches consists of computational modelling, which allows quantitative analysis of the mechanical behaviour of the valve by means of ...

Mitral valve reoperation, through a median sternotomy, for a patient with patent coronary bypass grafts is technically challenging and carries higher postoperative morbidity and mortality than a primary operation. We present a case of mitral valve repair using a beating heart technique under normothermic cardiopulmonary bypass that was performed 3 years after a coronary artery bypass operation....

Background—Durability assessment of mitral valve repair for degenerative valve incompetence is actually limited to reoperation as the primary indicator, with valve-related risk factors for late death as a secondary indicator. We assessed serial echocardiographic follow-up of valve function as an indicator of the durability of mitral valve repair. Methods and Results—In 242 patients who had unde...

OBJECTIVE Heart valve abnormalities are commonly found in patients with antiphospholipid syndrome but experience with valve replacement in such patients is limited. We analyzed the results of valve replacement in patients with this condition at our institution. METHODS Between 1989 and 2002, 10 patients with antiphospholipid syndrome (8 women, 2 men; aged 38-73 years, mean 49 years) with seve...

PURPOSE Late presence of mitral regurgitation (MR) after the Dor procedure (left ventricular (LV) reconstruction associated with coronary artery bypass grafting) for postinfarction patients carries a poor prognosis. The aim of this study was to review our experience with the Dor procedure and to analyze the correlation of surgical results with late MR. METHODS The study group comprised 19 pat...

BACKGROUND Mitral valve repair is favored over replacement due to superior outcomes. However, extensive infective endocarditis (IE) often has been considered unreconstructable. We retrospectively analyzed the mid-term outcomes of an individualized repair approach using a lifting annuloplasty strip. METHODS Between December 2007 and March 2014, 27 consecutive patients with acute single mitral ...

OBJECTIVE The Cox Maze procedure is widely performed for the surgical treatment of atrial fibrillation. However it requires numerous incision lines and therefore is a time-consuming operation. We report a simplified operation for chronic atrial fibrillation associated with mitral valve disease. METHODS Pulmonary vein isolation procedure was performed on atrial fibrillation associated with mit...

OBJECTIVES We developed and tested a novel transcatheter circumferential annuloplasty technique to reduce mitral regurgitation in porcine ischemic cardiomyopathy. BACKGROUND Catheter-based annuloplasty for secondary mitral regurgitation exploits the proximity of the coronary sinus to the mitral annulus, but is limited by anatomic variants and coronary artery entrapment. METHODS The procedur...

Background: Functional tricuspid regurgitation is a challenge regarding indications for repair and proper surgical technique. Aim of the study: We reviewed our midterm results of tricuspid valve repair for functional regurgitation comparing pericardial strip versus ring annuloplasties. Patients and methods: From January 2008 to December 2013, we operated 59 patients (male:female, 41:18, with a ...
