a total of 14 cases of infective endocarditis (ie) in children aged 6 months to 10 years were seen from december 1987 to december 1992 at the pediatric unit of ayatollah taleghani medical center. the majority of patients (12 of 14) were between 5 and 10 years of age. acyanotic congenital heart disease was known to preexist in 78.6% and rheumatic valvular heart disease in 21.4% of cases. organis...

Primary cardiac tumors are rare and myxoma is the most common tumor among them. Cardiac myxoma usually occurs in the left atrium. Myxoma originating from mitral valve is extremely rare. We report a case of mitral valve myxoma. The tumor originated from the anterior mitral valve leaflet. The tumor was completely removed and replacement of the mitral valve was not done.

Little is reported about primary cardiac osteosarcoma from mitral valve. We report a surgical case of primary cardiac osteosarcoma arising from mitral valve. The patient was a 54-year-old woman with congestive heart failure caused by mitral regurgitation due to a tumor (30 × 20 mm) from the posterior leaflet. We performed complete resection of the tumor combined with the mitral valve and replac...

A 31 year old woman was hospitalized for evaluation of aortic valve insufficiency and her present cardiac status. Clinical and paraclinical findings strongly suggested the presence of a collagen vascular inflammatory processprecisely, the antiphospholipid antibody syndrome (APS), with systemic lupus erythematosus as the underlying disease.

surgery for heart diseases during pregnancy, especially necessitating cardiopulmonary bypass, is believed to trigger maternal and fetal risks and should be performed only when medical therapy has been unsuccessful to alleviate the cardiac decompensation. a 33-year-old pregnant woman in her 33rd week of gestation was admitted to our hospital. she had rheumatic mitral valvular stenosis and had un...

mitral valve replacement (mvr) is usually performed in two methods of running and interrupted suturing. in running method, the suturing of the valve is usually with some traction on the annulus and also there is a risk of aortic valve injury. this study was conducted to evaluate a new technique for suturing to avoid these complications and decrease the time of cardiac arrest. one hundred and se...

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 ...
