Article Synopsis
  • The study investigates the use of 3D echocardiography (3D-echo) to detect and quantify myocardial infarct scars, compared to the standard method of delayed-enhanced cardiac magnetic resonance (DE-cMR).
  • Fifty patients with healed heart attacks and ten control subjects participated, undergoing both imaging methods to assess scar characteristics.
  • Results showed that 3D-echo had high sensitivity and specificity for detecting scars, with strong correlation to DE-cMR, suggesting it could be a valuable alternative for evaluating myocardial scarring.

Purpose: To prospectively determine whether cardiac-gated multidetector computed tomography (CT) allows visualization of aortic valve leaflets after bioprosthetic aortic valve replacement (AVR), to provide an accurate method for measuring the aortic valve opening, and to provide morphologic and functional information regarding the mechanism underlying poor function of the bioprosthetic valve.

Materials And Methods: The institutional review board approved the study protocol; informed consent was given. Fifty-four patients (27 men; mean age, 75 years + or - 8 [standard deviation]) with bioprosthetic AVR implanted 2 years + or - 3 earlier underwent 64-section CT and transthoracic echocardiography (TTE).

Aims: The management of asymptomatic severe mitral regurgitation remains controversial. The aim of the study was to assess the long-term survival, incidence of cardiac complications, factors that predict outcome, and effect of mitral surgery on the long-term prognosis of patients with asymptomatic severe mitral regurgitation amenable to valve repair.

Methods: One hundred ninety-two asymptomatic patients (mean age, 63 +/- 13 years) with severe degenerative mitral regurgitation diagnosed by 2-dimensional echocardiography between 1990 and 2001 were prospectively followed for a median of 8.

Objective: To assess the long-term survival, the incidence of cardiac complications and the factors that predict outcome in asymptomatic patients with severe degenerative mitral regurgitation (MR) undergoing mitral valve repair.

Methods: Up to 143 asymptomatic patients (mean age 63+/-12 years) with severe degenerative MR who underwent mitral valve repair between 1990 and 2001 were subsequently followed up for a median of 8 years. The study population was subdivided into three subgroups: patients with left ventricular (LV) dysfunction and/or dilatation (n=18), patients with atrial fibrillation and/or pulmonary hypertension (n=44) and patients without MR-related complications (n=81).
