hemolytic anemia is exceedingly rare and an underestimated complication after aortic valve replacement (avr).the mechanism responsible for hemolysis most commonly involves a regurgitated flow or jet that related to paravalvar leak or turbulence of subvalvar stenosis. it appears to be independent of its severity as assessed by echocardiography. we present a case of a 24-year-old man with a histo...
purpose : to determine the efficacy of three therapeutic regimens for the treatment of amaurosis fugax secondary to embolic sources from the heart methods : sixty patients randomly divided into 3 groups (20 patients in each group). group 1 received 100 mg aspirin/day, group 2 received the same dose of aspirin plus dipyridamole 75 mg twice daily and group 3 received 10 mg warfarin for 3 days fol...
Use of transcatheter mitral valve replacement (TMVR) using aortic valves in clinical practice is limited to patients with failing bioprostheses and rings or disease associated severe annulus calcification. Whereas the use valve-in-valve TMVR appears be a reasonable alternative surgery at high surgical risk, much less evidence supports valve-in-ring valve-in-mitral calcification interventions. D...
Experimental coronary occlusions were carried out in 12 closed-chest dogs to investigate the functional anatomic characteristics of the mitral valve complex during acute myocardial ischemia. Two-dimensional echocardiography was used to assess left ventricular function, the mitral valve complex, and left atrial size. Presence of mitral regurgitation was assessed by left ventricular contrast echo...
Although bicuspid aortic valve occurs in an estimated 1% of adults and mitral valve prolapse in an estimated 5% of adults, occurrence of the 2 in the same patient is infrequent. During examination of operatively excised aortic and mitral valves because of dysfunction (stenosis and/or regurgitation), we encountered 16 patients who had congenitally bicuspid aortic valves associated with various t...
INTRODUCTION Mitral valve repair is the treatment of choice to correct mitral insufficiency, although the literature related to mitral valve annulus behavior after mitral repair without use of prosthetic rings is scarce. OBJECTIVE To analyze mitral annulus morphology and function using real time tridimensional echocardiography in individuals submitted to mitral valve repair with Double Teflon...
Echocardiography is an essential tool in managing patients with mitral regurgitation. It allows identification and precise summation of anatomic lesions that lead to valve dysfunction. In this article, we highlight important aspects of mitral valve anatomy and pathophysiology as they pertain to surgical repair and discuss the critical role of echocardiography in surgical planning and assessment...
Mitral valve prolapse is a common mitral valve disorder manifested clinically as a midsystolic click and/or a late systolic murmur (the click-murmur syndrome) and pathologically as billowing or prolapsing mitral leaflets (the floppy valve syndrome). Not only is it one of the two most common congenital heart diseases and the most common valve disorder diagnosed in the United States, but it is al...
OBJECTIVES An increasing number of octogenarians are referred to undergo mitral valve surgery for degenerative disease, and percutaneous approaches are being increasingly used in this subgroup of patients. We sought to determine the survival and its predictors after Mitral Valve Surgery in Octogenarians (MiSO) in a multicenter UK study of high-volume specialized centers. METHODS Pooled data f...
Transcatheter valve implantation is a novel interventional technique, which was developed as an alternative therapy for surgical aortic valve replacement in inoperable patients with severe aortic stenosis. Despite limited experience in using transcatheter valve implantation for mitral and aortic regurgitation, transapical transcatheter aortic valve implantation and valve-in-valve implantation ...
