BACKGROUND We sought to determine whether right ventricular stunning could be detected after supply (during coronary balloon occlusion [BO]) and supply/demand ischemia (induced by rapid pacing [RP] during transcatheter aortic valve replacement) in humans. METHODS AND RESULTS Ten subjects with single-vessel right coronary artery disease undergoing percutaneous coronary intervention with normal...

To assess left ventricular (LV) diastolic filling in children with pressure overload hypertrophy, 12 patients with LV outflow obstruction (7 with aortic valve stenosis and 5 with aortic coarctation) and 12 healthy, age-matched control subjects were examined. Each child underwent M-mode echocardiography and pulsed Doppler examination of the LV inflow. The patients with LV outflow obstruction had...

Diffusely increased glucose metabolic activity in the right and left ventricles using 2-deoxy-2-(F-18) fluoro-D-glucose positron emission tomography/computed tomography (18F-FDGPET/CT) and global left ventricular hypokinesia at echocardiography can be evident in acute myocarditis. But, there has been no case report that the ventricular 18F-FDGuptake remains unchanged even ...

OBJECTIVE To assess the benefit resulting from the use of abciximab associated with primary angioplasty. The following parameters were analyzed in-hospital, at 30 days, and 6 months: (a) flow in the culprit artery; (b) ventricular function; (c) combined outcome of death, acute myocardial infarction, and additional revascularization. METHODS From November 1997 to June 1999, a longitudinal nonr...

markedly depressed left ventricular function is associated with a poor prognosis.1 C o r o n a r y artery bypass graft surgery has been the mainstay of treatment in such patients in the past but is associated with significant morbidity and mortality.2,3 Coronary angioplasty has been offered as an alternative to coronary artery bypass surgery in these patients. The results of PTCA in patients wi...

A 57 year old man was admitted for investigation of recurrent syncopal attacks. Holter monitoring during an attack while in hospital revealed a unique sequence of gross ST segment elevation, ventricular tachycardia, prolonged ventricular fibrillation, asystole, junctional and ventricular escape rhythm, and finally spontaneous restoration of sinus rhythm with severe ST segment depression. Subseq...

We describe a patient with ischemically mediated sustained monomorphic ventricular tachycardia occurring at rest and resistant to treatment with intravenously administered procainamide. Percutaneous transluminal coronary angioplasty was initially successful, but rest angina and ventricular tachycardia, resistant to procainamide therapy, recurred 2 weeks later and responded to aggressive anti-is...

this paper presents the case of a 35 year-old woman with symptoms of heart failure from the last month. a physical examination at admission showed paleness, dyspnea, peripheral edema and fatigue. in a two-dimensional echocardiography and transesophageal echocardiography, normal thickness but severe left and right ventricular dysfunction with severe pericardial effusion and thickened pericardium...
