The patient is a 54-year-old asymptomatic male with a tumor in the right atrium that was diagnosed on transesophageal echocardiography and confirmed as a lipoma of the right atrium on computerized tomography. The patient underwent surgical repair with extracorporeal circulation. The tumor was resected, and its base of implantation in the atrium was repaired with a flap of bovine pericardium. Th...

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...

With its unique en face view, real time three-dimensional transesophageal echocardiography has been reported to be more precise than conventional two-dimensional studies in evaluating mitral regurgitation etiology, and can locate diseased segments correctly. We present a case with severe mitral regurgitation due to anterior mitral leaflet perforation. Intraoperative real time three-dimensional ...

Echocardiography is a key assessment tool for the evaluation of cardiac structure and function. The ability to image cardiac structures using 3-dimensional (3D) echocardiography is evolving. In this article, we present some of the key features of the emerging 3D technology and review its applications with an emphasis on real-time 3D transesophageal echocardiography.

OBJECTIVES This study investigated the accuracy of mitral inflow quantification using biplane transesophageal echocardiography. BACKGROUND Mitral stroke volume can be reliably quantified by transthoracic Doppler echocardiography, but previous studies involving monoplane transesophageal echocardiography have yielded mixed results. METHODS Thirty patients without mitral regurgitation were pro...

Echocardiography has become the primary imaging tool in the diagnosis and assessment of congenital and acquired heart disease in infants, children, and adolescents. Transthoracic echocardiography (TTE) is an ideal tool for cardiac assessment, as it is noninvasive, portable, and efficacious in providing detailed anatomic, hemodynamic, and physiologic information about the pediatric heart. Recomm...

Despite its current limitations transthoracic echocardiography is still widely used for the anatomical and functional evaluation of patients with infective endocarditis. However, all these limitations can be overcome by using transesophageal echocardiography. We present the case of a 42-year-old male patient, diagnosed with aortic valve infective endocarditis, whose transthoracic echocardiograp...

INTRODUCTION Microembolic signals are usually detected with transcranial doppler during cardiac surgery.This report focuses on suggesting the transesophageal echocardiography as a different diagnostic approach to detect microemboli during cardiopulmonary bypass. CASE PRESENTATION A 58 year old male patient, caucasian race, was operated on video assisted minimally invasive mitral valve repair ...

BACKGROUND During the perioperative period an adequate intravascular volume must be maintained. Current recommendations overestimate perioperative volume requirements. AIM To compare perioperative volume administration using standard monitoring methods or guided by left ventricular filling parameters. MATERIAL AND METHODS Twenty-four patients subjected to colon resection were randomized to ...
