OBJECTIVE We evaluated the feasibility, safety, and diagnostic accuracy of noninvasive pacemaker stress echocardiography (PASE) test as a potential alternative to exercise or pharmacologic stress in patients with suspected or known coronary artery disease (CAD). BACKGROUND Transesophageal atrial pacing echocardiography is an accurate test for detection of(More)
Previous studies have shown that abnormal mitral flow patterns and left atrial (LA) enlargement are independently associated with survival in patients with left ventricular (LV) dysfunction. However, it is not known whether these outcome indicators can provide different information in patients of various age groups. This study was designed to assess the(More)
We report the results of intra-arterial digital subtraction angiography (DSA) in 100 patients with portal hypertension. The portal venous system was evaluated; all patients underwent angiography of the celiac and superior mesenteric arteries before surgery. Forty-four of them were also examined after Warren splenorenal shunts. Therefore, a total of 144(More)
This study assessed whether Doppler-derived mitral and pulmonary venous flow parameters were predictors of pulmonary artery hypertension in patients with left ventricular dysfunction. Doppler echocardiographic examinations were performed in patients (n = 100) with dilated cardiomyopathy in sinus rhythm either symptomatic or asymptomatic before and after(More)
OBJECTIVES Studies on the diagnostic value of exercise electrocardiography in right bundle branch block produced controversial results, and data on the accuracy of stress echo are still lacking. The aim of the study was to compare the diagnostic value of exercise electrocardiography and dipyridamole stress echo in chest pain patients with right bundle(More)
AIM Evaluation of the safety of percutaneous dilational tracheostomy (PDT) for perioperative, early and late complications. METHODS DESIGN we prospectively collected complications in patients who underwent PDT for mechanical ventilation; patients were interviewed 8 months after discharge, symptomatic cases underwent ENT control. SETTING 10 bed(More)
BACKGROUND Dipyridamole stress echo (DSE) positivity is usually titrated according to presence and severity of the induced wall motion abnormalities. The purpose of our study is to assess whether the location of DSE positivity might add to prognostic stratification. METHODS The study enrolled 112 patients with known or suspected coronary artery disease(More)
Ninety patients with cirrhosis undergoing elective distal splenorenal shunt (DSRS) for variceal bleeding between January, 1977 and September, 1988 comprised the study group. In 63 cases, the original technique of Warren was used and, in 15, the modified Britton procedure was employed. Twelve patients had a DSRS plus splenopancreatic disconnection.(More)
We report the experience of our general hospital in selecting the patients for orthotopic liver transplantation (OLT). Fifty-one patients with cirrhosis were examined and 20 of them submitted to OLT from August, 1992, to November, 1995. For liver studies, the 20 transplant recipients were examined with US and plain and dynamic CT; 15/20 were submitted to(More)
