A 32-year-old male patient was admitted to our clinic with complaints of exertional chest pain and shortness of breath. His blood pressure was 120/70 mmHg and his heart rate was 80 bpm. In the physical examination, Grade II/IV mid-diastolic murmur was noted at the cardiac apex with a harsh S1. His electrocardiogram was within normal limits. In transthoracic echocardiography, a mobile, heterogen...

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...

In 1957, Forster, Roughton, and their associates reported a method of estimating pulmonary capillary blood volume (Vc) and diffusing capacity of the alveolar-capillary membrane (DM) by measuring the diffusing capacity of the lung for carbon monoxide (DL) at varying levels of alveolar oxygen tension (1, 2).1 Since then there hlave been a number of reports on the behavior of membrane diffusion an...

BACKGROUND There are two competing theories of the mechanism of blood flow during cardiopulmonary resuscitation. The "cardiac pump" theory postulates that blood flows because the heart is squeezed between the sternum and the spine. The "thoracic pump" theory postulates that blood flows from the thorax because intrathoracic pressure exceeds extrathoracic vascular pressure and that flow is restri...

INTRODUCTION Mitral valve repair is the treatment of choice to correct mitral insufficiency, although the literature related to mitral valve annulus behavior after mitral repair without use of prosthetic rings is scarce. OBJECTIVE To analyze mitral annulus morphology and function using real time tridimensional echocardiography in individuals submitted to mitral valve repair with Double Teflon...

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...

BACKGROUND Because of safety, repeatability, and portability, clinical echocardiography is well established as a standard for cardiac anatomy, cardiac function, and hemodynamics. Similarly, application of echocardiography in commonly used rat experimental models would be worthwhile. The use of noninvasive ultrasound imaging in the rat is a potential replacement for more invasive terminal techni...

In order to establish the relative prevalence of mitral valve prolapse as diagnosed by two dimensional echocardiography, we studied 100 presumably healthy young women with two dimensional echocardiography and M-mode echocardiography, history, physical examination, electrocardiography, and phonocardiography. Two dimensional echocardiograms were obtained from parasternal, apical, and subcostal ac...

Real-time three-dimensional transesophageal echocardiography (RT3DTEE) is now commonly used in daily clinical practice. The transesophageal, compared to the transthoracic approach, allows the visualization of the whole spectrum of the mitral valve apparatus and the posterior cardiac structures. Moreover, images obtained by RT 3D TEE provide a unique and complete visualization of the mitral valv...
