Color Doppler echocardiography does not provide adequate information about the severity of mitral regurgitation in patients with eccentric mitral regurgitation. We have developed a new procedure for 3-dimensional (3D) color Doppler reconstruction and for segmentation of regurgitant jets. The volume of regurgitant jets was compared with jet area in 63(More)
OBJECTIVES The purpose of this study was to assess the clinical feasibility of three-dimensional (3D) reconstruction of color Doppler signals in patients with mitral regurgitation. BACKGROUND Two-dimensional (2D) color Doppler has limited value in visualizing and quantifying asymmetric mitral regurgitation. Clinical studies on 3D reconstruction of Doppler(More)
INTRODUCTION/PURPOSE The complexity of cardiac surgery requires continuous training, education and information addressing different individuals: physicians (cardiac surgeons, residents, anaesthesiologists, cardiologists), medical students, perfusionists and patients. Efficacy and efficiency of education and training will likely be improved by the use of(More)
OBJECTIVE Transesophageal color Doppler (or 2D Doppler) is the most widely used technique for intraoperative assessment of mitral valve repair. However, the most severe mitral regurgitations produce eccentric jet flows which cannot be assessed by 2D imaging. Up to now the indications for surgical intervention and intraoperative decisions after valve repair(More)
From 1975 to 1985, a total of 1596 coronary artery bypasses or valve replacements resulted in 18 gastrointestinal tract complications in 16 patients at Good Samaritan Hospital in Cincinnati. Twelve patients were treated surgically (hemorrhagic duodenal ulcer, one patient; perforated duodenal ulcer, one patient; cholecystitis: acalculous, gangrenous, two(More)
BACKGROUND Cardiac functional assessment represents the basis for diagnostics and cardiac operation planning. Spiral computed tomography (CT) combines the advantages of three-dimensional imaging and high temporal resolution when using gating techniques. However, in vivo validation data of this novel imaging technology are lacking. The purpose of this study(More)
Recurrent thoracic outlet syndrome that requires reoperation accounts for 1% of first rib resections. Symptoms in a series of 30 patients were mainly neurological and consisted of pain and paresthesia involving the neck, shoulder, arm, and hand and were severe and unrelenting. Recurrence of symptoms ensued from one month to seven years following initial rib(More)
The benign condition of isolated first rib fracture is compared with the severity of intrathoracic injuries resulting from first rib fracture associated with multiple rib injuries. Seventy-five patients with 90 first rib fractures were divided into two groups. Group 1 (n = 13) included those with isolated first rib fractures and Group 2 (n = 62), those with(More)
BACKGROUND Myocardial edema (ME) adversely affects ventricular function. Thus, we performed an animal study to demonstrate (1) 3D-ME using magnetic resonance imaging (MRI), which can show ME depending on myocardial location, (2) type of cardioplegic solution, and (3) quantification tools. METHODS Pig hearts (n = 22) were perfused using Bretschneider's(More)
