relation between capillary wedge pressure measured by echocardiography through tissue doppler imaging (tdi) method and catheterism in patients with mitral valve stenosis
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...
متن کاملValve Calcification in Aortic Stenosis: Etiology and Diagnostic Imaging Techniques
Aortic stenosis is the most common valvulopathy in the Western world. Its prevalence has increased significantly in recent years due to population aging; hence, up to 8% of westerners above the age of 84 now have severe aortic stenosis (Lindroos et al., 1993). This causes increased morbidity and mortality and therein lies the importance of adequate diagnosis and stratification of the degree of ...
متن کاملDoppler echocardiographic findings in tissue engineered aortic valve in a sheep model
Background: Heart valve diseases are considered a common disease in human and animals, and valve replacement is an option for treatment of valvular diseases. Objectives: In this study efficacy of a tissue engineered valve in thoracic aorta was evaluated with transthoracic echocardiography. Methods: This study was undertaken on 6 male sheep. Echocardiography was performed on all sheep 24 hours b...
متن کاملPrognostic Value of Aortic Valve Area by Doppler Echocardiography in Patients With Severe Asymptomatic Aortic Stenosis
BACKGROUND The aim of this study was to evaluate the relationship between aortic valve area (AVA) obtained by Doppler echocardiography and outcome in patients with severe asymptomatic aortic stenosis and to define a specific threshold of AVA for identifying asymptomatic patients at very high risk based on their clinical outcome. METHODS AND RESULTS We included 199 patients with asymptomatic s...
متن کاملtissue doppler imaging findings including prominent s wave in patients with mitral valve prolapse syndrome
conclusions sm wave in tdi is prominent and significantly high in mvp syndrome. also, our study showed some degree of diastolic dysfunction in mvp patients. results seventy-five patients (48 females) at a mean age of 26.5 ± 9.4 years and 50 individuals (32 females) at a mean age of 27.1 ± 8.3 years were enrolled in the study. as the important results of our study, sm wave was much more prominen...
