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...

abstractthe valves of right horn of systemic venous sinus are prominent structures within the right atrium during early embryonic period. involution of these structures may not be complete, resulting in a spectrum of anatomical presentations such as cyanosis. a full-term male neonate referred to our hospital for precise evaluation of severe cyanosis on the first day of life. echocardiographic e...

this report presents a case of left radial artery pseudoaneurysm developing at the previous site of invasive monitoring. the patient had prosthetic mitral valve replacement one month earlier, and anti-coagulation therapy had started on the first post-operative day. the patient’s radial artery aneurysm with a 4-centimeter diameter was resected and the radial artery was ligated.

background: conventional doppler measurements, including mitral inflow and pulmonary venous flow, are used to estimate left ventricular end diastolic pressure (lvedp). however, these parameters have limitations in predicting lvedp among patients with mitral regurgitation. this study sought to establish whether the correlation between measurements derived from tissue doppler echocardiography and...

background: percutaneous balloon mitral valvotomy (bmv) is the gold standard treatment for rheumatic mitral stenosis (ms) in that it causes significant changes in mitral valve area (mva) and improves leaflet mobility. development of or increase in mitral regurgitation (mr) is common after bmv. this study evaluated mr severity and its changes after bmv in iranian patients. methods: w e prospecti...

background: blood viscosity and aortic sclerosis (as) are strong predictors of cardiovascular events. the effects of blood viscosity on as have not been studied adequately. we aimed to investigate the potential connection between whole blood viscosity (wbv) and as. methods:   as was detected by transthoracic echocardiography. the estimation of wbv was carried out at both high shear rate (hsr) (...

purpose: to determine the prevalence of keratoconus (kcn) in patients with mitral valve prolapse (mvp). methods: this descriptive study was conducted on patients with mvp at shahid rajaei hospital during 2003-2004. corneal topography was performed in 392 subjects with absolute mitral valve prolapse based on perloff’s major criteria. orbscan was carried out in suspected kcn cases. results: patie...

Background Total correction of Tetralogy of Fallot (TOF) anomaly in early childhood has been practiced in many centers with good results, but in some of patients after few years sever Pulmonary valve insufficiency occurred. Materials and Methods At a cross- sectional study from January 2015 to January 2016, 10 patients who had history of primary repair of TOF with free pulmonary insufficiency (...

to investigate the prevalence of mycobacterium paratuberculosis (m. avium subsp. paratuberculosis)infection among cattle slaughtered in ahvaz abattoir, samples were taken from 250 cattle. before slaughter,sex and age were assessed. thereafter, samples were taken from ileocecal valve, rectum mucosa, ileocecallymph node and stool. all smears which taken from these samples were stained by ziehl-ne...

abstract a 49-year-old man with lutembacher's syndrome associated with frontal meningioma referred to our hospital. he also suffered from exertional dyspnea. transthoracic echocardiography demonstrated mitral valve area of 1.48 cm2, moderate mitral stenosis, and left atrial dimension (lad) of 5.6 cm with no clot. tee revealed severe mitral stenosis, mitral valve area of 1.05 cm2 with wilki...
