"No culprit" ST-elevation myocardial infarction: role of cardiac magnetic resonance imaging.

Patients with presumed ST-elevation myocardial infarction (STEMI) have no clear culprit artery in approximately 10-15% of cases. We examined the value of cardiac magnetic resonance (CMR) for diagnosis in patients with "no culprit" STEMI. Data from a comprehensive prospective registry of STEMI patients were reviewed from March 2003 to December 2009.

Identification of unexpected nonatherosclerotic cardiovascular disease with coronary CT angiography.

Objectives: The aim of this study was to assess, in a general cardiology cohort screened for obstructive coronary artery disease (CAD), the effectiveness and frequency with which multidetector computed tomography (MDCT) angiography unexpectedly imaged and identified other nonatherosclerotic cardiovascular diseases.

Background: MDCT angiography is a novel imaging strategy employed primarily to diagnose CAD that, in the course of these studies, can also potentially identify other important but previously unrecognized cardiovascular abnormalities.

Methods: Consecutive 64-slice MDCT angiography studies were obtained in 4,543 patients with suspected atherosclerotic CAD at the Minneapolis Heart Institute, over a 29-month period (2005 to 2007).

Radiation following percutaneous balloon aortic valvuloplasty to prevent restenosis (RADAR pilot trial).

Objectives: We wished to determine the feasibility and early safety of external beam radiation therapy (EBRT) used following balloon aortic valvuloplasty (BAV) to prevent restenosis.

Background: BAV for calcific aortic stenosis (AS) has been largely abandoned because of high restenosis rates, i.e.

Acute and reversible cardiomyopathy provoked by stress in women from the United States.

Background: A clinical entity characterized by acute but rapidly reversible left ventricular (LV) systolic dysfunction and triggered by psychological stress is emerging, with reports largely confined to Japan.

Methods And Results: Over a 32-month period, 22 consecutive patients with this novel cardiomyopathy were prospectively identified within a community-based practice in the Minneapolis-St. Paul, Minn, area.
