Background: Percutaneous Transeptal Mitral Commisurotomy (PTMC) has been used in treating mitral stenosis with variable success, its main complication being mitral incompetence. There is a need to define the subgroup of the patients who benefit mostly from the procedure. Methods: We studied 110 patients (age 17 to 60 years mean 33.2) with mitral stenosis. PTMC was performed though femoral vein....
Accessory mitral valve tissue, a rare cause of left ventricular outflow tract obstruction, can be difficult to diagnose preoperatively and confusing even at surgery. The reported case illustrates how preoperative evaluation can be made using two-dimensional echocardiography combined with Doppler flow analysis. The intraoperative technique for removing the accessory tissue without causing damage...
background: primary intra cardiac tumors are rare. in this article, we present papillary fibroelastoma of mitral valve chordae. case presentation: a 35-year old man presented with atypical chest pain and palpitation. physical examination and electrocardiogram were normal. transesophageal echocardiography (tee) revealed a mass of 1015 mm attached to chordae of anteromedial papillary muscle of m...
We developed and validated a mitral valve orifice method for Doppler cardiac output determination. In 15 open-chest dogs, cardiac output was controlled and measured by a roller pump interposed between the right atrium and pulmonary artery as a right-heart bypass. Left heart flows were measured in the open-chest dog model by Doppler measurements at the mitral valve orifice and compared not only ...
BACKGROUND The mechanism of the late complications after coarctation repair remains unclear, and this common congenital heart disease affects patients and perplexes physicians in terms of prevention and treatment. METHODS From 2004 to 2008, 13 patients (1 adolescent and 12 adults) with repaired or unrepaired coarctation of the aorta were operated on in this department due to valve disorder or...
A lthough the incidence of mitral stenosis has declined precipitously in the Western world due to the reduced incidence of rheumatic heart disease, mitral regurgitation remains one of the most common valvular pathologies. Many patients affected by severe mitral valve disease are elderly with multiple comorbidities and are at high risk for traditional open surgical mitral valve repair or replace...
giant left atria are defined as those measuring larger than 8 cm and are typically found in patients who have rheumatic mitral valve disease with severe regurgitation. enlargement of the left atrium may create compression of the surrounding structures such as the esophagus, pulmonary veins, respiratory tract, lung, inferior vena cava, recurrent laryngeal nerve, and thoracic vertebrae and lead t...
