Silent cerebral infarction in chronic heart failure: ischemic and nonischemic dilated cardiomyopathy.

Objectives: Patients with dilated cardiomyopathy (DCM) may have a high incidence of clinically asymptomatic silent cerebral infarction (SCI). Prevalence of SCI and its risk factors may differ between ischemic and nonischemic DCM. The purpose of this study was to evaluate prevalence and related parameters of silent cerebral infarction in patients with ischemic and nonischemic DCM.

Multivessel variant angina after a radical nephrectomy operation.

A case of multivessel variant angina after an open radical nephrectomy operation (RNO) is presented. A 52-year-old man was admitted to the coronary care unit with recurrent chest pain and dynamic ST-T wave changes on electrocardiogram early after an RNO. The first diagnosis of the clinical condition was non-ST segment elevation acute coronary syndrome.

Two cases with similar pseudoaneurysms but different outcomes.

The pseudoaneurysm is a rare cardiac pathology, in which the left ventricular free wall ruptures and the pericardium surrounds the rupture in combination with thrombus and inflammation and thus prevents the development of a hemopericardium. Left ventricular pseudoaneurysm may remain silent unless it gives rise to cardiac tamponade, collapse, and finally sudden death. In this case report, we present two cases with left ventricular pseudoaneurysms in the same area.

Magnetic resonance imaging measurement of left ventricular blood flow and coronary flow reserve in patients with chronic heart failure due to coronary artery disease.

Background: Coronary sinus flow reflects global cardiac perfusion and has been used for the assessment of myocardial flow reserve, which is reduced in chronic heart failure(CHF). Coronary flow reserve (CFR) can be measured by using phase-contrast (PC)velocity-encoded cine (VEC) magnetic resonance imaging (MRI).

Purpose: To quantify and compare global left ventricular (LV) perfusion and CFR inpatients with CHF and in a healthy control group by measuring coronary sinus flow with PC VEC MRI, and to correlate this with global LV perfusion, segmental first-pass perfusion, and viability in the same patients.
