introduction: body mass index (bmi) can affect cardiac morphology; however, the relationship between bmi and valvular heart diseases has not been thoroughly evaluated. this study aimed to determine the relationship between bmi and mitral valve prolapse (mvp) as one of the most common valve diseases worldwide. it can help us to better understand pathophysiology of this common disease. materials ...

Introduction: Surgical valve replacement is not always feasible in patients with severe mitral regurgitation from a failing bioprosthetic valve or severe mitral annular calcification. Off-label use of transcatheter aortic valves has been described in the literature as a possible method of valve replacement for this patient population. We review the literature on this practice as well as present...

BACKGROUND We set out to evaluate mitral valve repair with the loop technique under dynamic conditions, using a U-Clip to anchor the loop unit to a papillary muscle. METHODS Mitral valve prolapse was artificially developed by resecting 4 chordae tendineae of a resected porcine heart. The loop unit was anchored to the papillary muscle using U-Clips. Each chordal loop was fixed on the prolapsed...

background: considering suggested formula in the references and pcwp measured by catheterism, in the present study the relation between pulmonary capillary wedge pressure (pcwp) measured the flow velocity of mitral valve and mitral annulus motion through tissue doppler imaging is evaluated methods: 52 cases of severe ms were admitted for balloon mitral valvolotomy (bmv) are included in this stu...

Surgicel, an absorbable haemostat, is widely used in cardiovascular surgery. An 81-year-old woman, who was diagnosed with ischaemic mitral regurgitation, underwent mitral valve plasty and coronary artery bypass grafting. On postoperative day two, her superior vena cava (SVC) pressure gradually rose to 38 mmHg and she developed low output syndrome. Emergent surgery revealed that the cause of SVC...

introduction: mitral stenosis is a narrowing or blockage of the opening of the mitral valve. symptoms usually develop between the ages of 20 and 50. it most commonly occurs in people who have had rheumatic faver. the purpose of this study was to determine the clinical, characteristics of mitral stenosis in men and women and their reactions to balloon mitral valvotomy (bmv).  materials and metho...

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...

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...
