It has been difficult to conduct large scale studies of microbiologically complex ecosystems using conventional microbiological techniques. Molecular identification techniques in new probe-target formats, such as checkerboard DNA-DNA hybridization, permit enumeration of large numbers of species in very large numbers of samples. Digoxigenin-labeled whole(More)
OBJECTIVES The purpose of this study was to examine whether left atrial (LA) mechanical function, as measured by LA total emptying fraction (TEF), is a predictor for the development of post-operative atrial fibrillation (POAF) following cardiac surgery. BACKGROUND POAF is an important and frequent complication of cardiac surgery. LA enlargement has been(More)
Left ventricular (LV) apical hypoplasia is an unusual, recently identified cardiomyopathy, whose clinical course is uncertain. In this report, we describe a case of this cardiomyopathy occurring in an asymptomatic 50-year-old male with a remote history of a surgically corrected patent ductus arteriosus (PDA), primarily using transthoracic echocardiography(More)
bosis of the hepatic, portal, superior mesenteric, and splenic veins. The patient did not have any previous history of liver disease and was not taking oral contraceptives. Hepatic and splanchnic venography confirmed thrombosis of the hepatic, superior mesenteric, portal, and splenic veins compatible with BCS and MVT. Because of worsening liver failure, a(More)
BACKGROUND AND AIM OF THE STUDY For patients with chronic severe mitral regurgitation (MR), one consideration for the timing of mitral valve surgery is the desire to have a preserved postoperative left ventricular ejection fraction (LVEF). It was hypothesized that the preoperative left ventricular (LV) volume and effective forward LVEF (defined as the ratio(More)
