OBJECTIVES to evaluate the structural and functional heart abnormalities in women with mitral regurgitation during pregnancy. INTRODUCTION Women with mitral regurgitation progress well during pregnancy. However, the effects on the heart of the association between pregnancy and mitral regurgitation are not well established. METHODS This is a case-control, longitudinal prospective study. Echo...

an 80-year-old diabetic man with severe aortic stenosis was admitted to our hospital for cardiogenic shock complicating non-st-elevation myocardial infarction. echocardiographic evaluation showed also a severe degree of both left ventricular dysfunction and mitral regurgitation. the patient was initially stabilized with inotropes and mechanical ventilation was necessary because of concurrent pu...

BACKGROUND To investigate the association between the coaptation height of mitral valve and mitral regurgitation after mitral valve repair. METHODS From Sep 2014 to Jun 2015, 20 patients underwent mitral valve valvuloplasty for mitral regurgitation were included. Ring annuloplasty was performed in all cases. Mitral valve short-axis dimension (MVd), coaptation height (CH), Left ventricular eje...

BACKGROUND This study was designed to evaluate the incidence and mechanisms of mitral regurgitation following mitral balloon valvotomy (MBV) in 40 consecutive patients with symptomatic tight pliable mitral stenosis. METHODS AND RESULTS Transthoracic echocardiography with color flow mapping was performed before and 24 hours after the procedure. Patients who developed significant mitral regurgi...

In this issue of JASE, Magne et al continue their previous work using echocardiography to analyze outcomes of mitral valve repair for ischemic mitral regurgitation, demonstrating that continued adverse left ventricular (LV) remodeling may not be a prerequisite for recurrent mitral valve regurgitation in patients who had undergone initially successful repairs. They observed a group of 26 patient...

OBJECTIVES This study was performed to examine the effect of dobutamine stress echocardiography on mitral regurgitation and to test the hypothesis that mitral regurgitation will increase in patients with an ischemic response. BACKGROUND New or worsening mitral regurgitation during stress testing has been proposed as a marker of ischemia. However, it is unclear whether ischemia induced by dobu...

Prosthetic aortic valve and conduit dehiscence with periconduit cavity and ascending aortic aneurysm is an uncommon complication of aortic root surgery. It is usually recognizable at echocardiography due to an abnormal position of the prosthetic valve and conduit in relation to the native aortic annulus in conjunction with an abnormal echolucent periconduit space that fills with color flow. Mit...

Mitral valvular regurgitation consistently modified the wave form of the first derivative of the transthoracic impedance cardiogram. The transthoracic impedance cardiogram was recorded in 23 control subjects (group 1), and 23 patients with isolated mitral regurgitation (group 2). Simultaneous transthoracic impedance cardiogram, electrocardiogram, and mitral valve echocardiograms in group 1 show...

The mitral valve apparatus is a complex anatomic and functional unit composed of the mitral annulus, valve leaflets, chordae, papillary muscles, and the underlying left ventricular wall. Normal function depends on both normal anatomy of each of these components and on the overall three dimensional relationships of these structures to each other, including the effects of overall left ventricular...

We evaluated auscultatory findings in a 67-year-old man with acquired pulmonic and mitral regurgitation. During inspiration, the murmur of pulmonic regurgitation decreased in intensity prior to surgery, but increased in intensity after mitral valve replacement. Inspiration reduces the volume of mitral regurgitation, thereby reducing the volume and murmur of pulmonic regurgitation.
