Reoperation is the method of choice for correcting prosthetic paravalvular leaks. The percutaneous repair of mitral paravalvular leaks might represent an interesting alternative in select cases. The present study reports two cases of mitral paravalvular leaks that were treated with AmplatzerTM Vascular Plug III guided by three-dimensional (3D) transesophageal echocardiography, using the percuta...

Right atrial dilation due to left heart disease is a common complication among adults. The present review aimed to describe a case of massively dilated right atrium in a female patient presenting with valvular heart disease and no atrial fibrillation. The results of chest X-ray revealed a large opacity filling the lower right hemithorax, falsely interpreted as a mediastinal mass. During the tra...

Experimental coronary occlusions were carried out in 12 closed-chest dogs to investigate the functional anatomic characteristics of the mitral valve complex during acute myocardial ischemia. Two-dimensional echocardiography was used to assess left ventricular function, the mitral valve complex, and left atrial size. Presence of mitral regurgitation was assessed by left ventricular contrast echo...

This paper presents a semi-automatic method for tracking the mitral valve leaflet in transesophageal echocardiography. The algorithm requires a manual initialization and then segments an image sequence. The use of two constrained active contours and curve fitting techniques results in a fast segmentation algorithm. The active contours successfully track the inner cardiac muscle and the mitral v...

OBJECTIVE To study mitral valve function in the postoperative period after correction of the partial form of atrioventricular septal defect. METHODS Fifty patients underwent surgical correction of the partial form of atrioventricular septal defect. Their mean age was 11.8 years and 62% of the patients were males. Preoperative echocardiography showed moderate and severe mitral insufficiency in...

In a patient with endocarditis and significant aortic insufficiency, two-dimensional echocardiography revealed an abnormal mitral valve configuration with division of the valve into two separate orifices. At autopsy, a double orifice mitral valve with two sets of valve leaflets was observed. Appreciation of this echocardiographic abnormality is important because double orifice mitral valve is a...

We tested the hypotheses that Doppler echocardiography has a higher accuracy than clinical evaluation in the detection of significant aortic and mitral valvular heart disease and that Doppler echocardiography is highly accurate as compared with cardiac catheterization for the assessment of valvular disease severity. Thus, cardiac catheterization for the assessment of valve lesion severity may b...

A 60-year-old male presented with renal failure and right coronary myocardial infarction. Transesophageal echocardiography showed many tumors (Fig. 1). Endoscopy showed multiple ectopic calcifications in a line on the mitral annulus (Fig. 2). Ectopic calcifications were removed and mitral valve annu-plasty was performed. Histopathologic examination confirmed these were dense calcifications. Fig...

A 32-year-old patient with symptomatic severe aortic regurge, 6 weeks after mitral valve repair, was admitted for aortic valve surgery. No preoperative clinical data consistent with infective endocarditis could be detected. Preoperative transthoracic echocardiography showed aortic leaflet perforation affecting non coronary cusp. During operation, leaflet perforation was detected and closed comp...
