Background Cardiac MRI is used to measure right ventricular end diastolic volume indexed to body surface area (RVEDVi) and ejection fraction (EF) in the setting of pulmonary insufficiency (PI). There is data describing optimum RVEDVi, in tetralogy of fallot (TOF) patients, to provide a competent pulmonary valve and maintain long term RV function. Pulmonary atresia with intact ventricular septum...

endocarditis is rarely reported in sheep and information presented for ovine endocarditis is based mostly on comparative findings in the cattle. infective vegetative endocarditis of the right heart was diagnosed in a 3-year-old fat-tailed ram. clinical findings included tachycardia, marked brisket edema, jugular veins distention and pulsation and pale mucous membranes. hematologic abnormality i...

(Leipzig, Germany): I commend you for your courage in using a new product designed for a completely different purpose, but which works well. My first question is, what are your indication criteria because you have patients with a moderate stenosis and moderate insufficiency, a mean of 1.8 and a mean gradient of 54? Dr Nosál': Typically our patients have a mixed aortic valve pathology, so the me...

conclusions children with chd are at risk of severe complications with the involvement of other organs. long-term febrile illness should be taken seriously in these children. they need hospitalization and careful evaluation. case presentation a 6-year-old girl with a ventricular septal defect (vsd) was presented. echocardiography revealed large vegetation in the right ventricular outflow tract ...

Percutaneous pulmonary valve replacement is one of the most important advancements in the field of interventional cardiology in the past decade.1,2 However, currently available technologies are not applicable to patients with oversized right ventricular outflow tracts (RVOTs), especially when there is concomitant proximal branch pulmonary artery (PA) stenosis. This combination commonly is encou...

Methods 148 consecutive patients with type A TAAD were operated on during 2010 2012 (122 (82,4%) males). Their age ranged 20 – 77 years, mean 49,3 ± 9,6. Acute (subacute) dissection was in 128 (86,5%), chronic – in 20 (13,5%). The causes of aneurysms forming were: arterial hypertension, atherosclerosis – in 91 (61,5%); BAV – 18 (12,2%); MS – 16 (9,8%); cystomedianecrosis – 16 (10,8%); blunt aor...

The causes of mitral valve insufficiency may largely be divided into two categories: organic or primary and functional or secondary. In the first case, the cause of insufficiency is due to a morphological change of the valve. Numerous diseases may damage the valve. Of the degenerative disease we may list myxomatous degeneration, fibroelastic deficiency or annular calcifications. Of the phlogist...

blunt chest traumas mostly occur due to car accidents and can cause many cardiac complications such as septal rupture, free-wall rupture, coronary artery dissection or thrombosis, heart failure, arrhythmias, and chordae and papillary muscle rupture. one of the most serious complication is tricuspid regurgitation (tr), which can be simply diagnosed by physical examination and confirmed by echoca...

background: discrete subaortic stenosis (dss) is a progressive condition. controversy still rumbles on as to whether the subaortic membrane causes aortic regurgitation (ar) and whether membrane resection reduces ar severity. we investigated the association between the left ventricular outflow tract peak gradient (lvot-pg) and ar severity preoperatively and changes in ar severity and obstruction...

background: several competing geometric and hemodynamic factors are suggested as contributing mechanisms for functional mitral regurgitation (mr) in heart failure patients. we aimed to study the relationships between the severity of mr and the qrs duration and dyssynchrony markers in patients with ischemic or dilated cardiomyopathy. methods: w e prospectively evaluated 251 heart failure patient...
