THE PROLAPSED MITRAL VALVE, or clickmurmur syndrome, continues to evoke interest, concern and controversy. Although the midsystolic click and late systolic murmur were well described in the late 19th century,1 it was not until 1961 that Reid2 suggested the mitral valve as the cause of the click and mitral insufficiency as the cause of the murmur. This was confirmed by angiocardiography and phon...

OBJECTIVE An animal model has been designed to assess the feasibility of off-pump mitral valve replacement using valved stents. METHODS Glutaraldehyde-preserved homograft was sutured inside a prosthetic tube (Dacron). Then, two self-expandable nitinol Z-stents were sutured on the external surface of the prosthesis in such a way to create two self-expanding crowns for fixation. In adult pigs a...

Mitral valve insufficiency is frequently the result of elongated or ruptured chordae tendineae. Several techniques have been described for its correction. However, when there is a severe elongation or rupture of the chordae, the most widely accepted treatment option has been valve replacement. The best long-term outcomes observed in conservative surgeries led us to choose this procedure rather ...

INTRODUCTION Mitral valve repair is the treatment of choice to correct mitral insufficiency. Although the literature related to left atrial and ventricular behavior after mitral repair without use of prosthetic rings is scarce. OBJECTIVE To analyze cardiac morphology and function using real time tridimensional echocardiography in individuals submitted to mitral valve repair with Double Teflon...

T HE INFREQUENT REPORTS of mitral insufficiency on a congenital basis rcflect the apparent rarity of this condition. Aneurysmal dilatation of the left atrium in a 5year-old girl with clinical findings suggesting mitral insufficiency has been described by Semans and Taussig in 1938.1 Postmortem examination of this patient revealed thickening of the mitral and tricuspid valves, saccular dilatatio...

Mitral insufficiency results from a failure of the valve leaflets to meet during ventricular systole. During exploratory surgery on patients afflicted with this disease, the observation was made by the authors and others1 that the regurgitant jet could be effectively controlled by the surgeon’s index finger with significant improvement in the action of the heart as long as the finger remained a...

   Introduction: Retinal vein occlusion  is a common vascular disorder disrupting vision. Two basic types of RVO are branch retinal vein occlusion and central retinal vein occlusion (CRVO).  Retinal vein occlusion is a multifactor process including systemic illness and local retinal factors.RVO may be associated with atherosclerotic risk factors. We analyzed the role of 2 dimensional transthor...

Severe haemolytic anaemia developed in a 33 year old patient after the mitral valve was replaced with a St Jude medical prosthesis. This was the patient's third thoracotomy. She had already had a mitral commissurotomy and a mitral valve bioprosthesis. The patient had an E+ antibody to red blood cells as well as a paraprosthetic leak. The haemolysis became less severe once the population of E+ r...

BACKGROUND To report early and long-term outcomes of patients undergoing minimally invasive mitral valve surgery (MIMVS) through right mini-thoracotomy (RT) over a 10-year period. METHODS From September 2003 to December 2013, a total of 1604 consecutive patients underwent MIMVS through RT. RESULTS The mean age was 63 ± 13 years, 770 (48 %) patients were female and 218 (13.6 %) had previous ...

Two cases of mitral insufficiency are reported. In 1 case the lesion was produced by rupture of the chordae tendineae of the posterior leaflet of the mitral valve. In the other case it was produced by fibrous adhesion of the posterior leaflet of the mitral valve to the underlying left ventricular wall, which occurred during healing of subacute bacterial endocarditis. Changes occurred in the pul...
