Minimally invasive mitral valve repair is based on several procedural concepts. Recently, three of them have been intensively discussed: aortic occlusion strategy, use of Goretex-Neo-Chordae to repair mitral valve regurgitation and feasibility and efficacy of the minithoracotomy approach in mitral valve treatment of patients after previous cardiac surgery. Twenty years of experience in minimall...

Phonocardiographic, hemodynamic, angiographic, and cardiac echographic studies have been performed on 11 patients whose diseased mitral valves have been replaced by a supported aortic valve homograft. The chordae tendineae and papillary muscles were removed in all patients during the operation. Apical first heart sounds of normal intensity were present in all patients after surgery. Nine patien...

A Chinese woman was admitted to our hospital because of syncope. Transthoracic echocardiography revealed a hypertrophic basal interventricular septum of 15 mm with a sharp angle protruding into the left ventricular outflow tract. Moreover, an anomalous anterolateral papillary muscle (maximum width of 11 mm) was inserted into the left ventricular outflow tract, with short chordae tendineae conne...

Myxomatous mitral regurgitation (type II Carpentier's functional classification) affects about 1-2% of the population. This represents a very common indication for valve surgery resulting in a low percentage of repairs compared to replacement which is actually performed. In the last decades, several methods for mitral valve repair have been developed, to make the surgical feasibility easier, im...

In patients with active infective endocarditis mitral valve repair is better than mitral valve replacement, but it remains a challenge when there has been massive destruction of the rough zone of the anterior leaflet. We report a technical modification of mitral valve repair for advanced active infective endocarditis in which a widely infected rough zone and the chordae were successfully replac...

Objective: Mitral valve repair in rheumatic patients is still a challenge. The aim of this study is to assess the results of mitral valve repair in rheumatic patients with rheumatic mitral insufficiency. Methods: 330 patients with rheumatic mitral insufficiency who had undergone mitral valve repair in the Heart Institute HC-FMUSP were assessed retrospectively, between 1985 and 2005. The mean ag...

OBJECTIVES The present study was designed to evaluate the effects of surgical procedure on left ventricular systolic and diastolic function in patients with mitral regurgitation. BACKGROUND Left ventricular systolic function has been shown to decline after operation in patients with chronic mitral regurgitation. METHODS Using simultaneous cineangiography and left ventricular micromanometry,...

Rheumatismal lesions of the mitral valve a!I'e rare under the age of six and surgical iruter­vention in symptomatic patients is an academic problem. Early surgical treatment has been done to prevent serious changes and unrevers­ib1e complications o.f the heart and lungs.  From April 71 until April 74, thirty-five pati­ent, ranging between 8-18 years of age, suffer­ing of <lifferents heart ,tro...
