Abstract

To compare tomographic and planar radionuclide ventriculography (RNVG) in assessing regional left ventricular (LV) function and predicting improvement in LV ejection fraction (LVEF) after operation in patients with LV aneurysm, 18 patients with aneurysm underwent both tomography and planar RNVG 1 month before and 3 weeks to 6 months after aneurysmectomy and coronary artery bypass grafting. All patients also underwent preoperative contrast angiography at catheterization. The percent shortening of the apical, anterior, lateral, inferior, and basal segments was calculated from tomographic long-axis and short-axis slices and corresponding planar images (anterior and 30- and 70-degree left anterior oblique views). No significant differences in anterior, apical, and lateral percent shortening were apparent before aneurysmectomy between tomographic and planar studies. However, preoperative basal percent shortening was 47% +/- 13% from tomographic and 28% +/- 14% from planar images (p < 0.001). Preoperative tomography generally agreed better with contrast angiographic results than did planar imaging. After aneurysmectomy, basal function improved to 57% +/- 12% (p < 0.01) by tomography. For all patients, LVEF increased from 29% +/- 8% b...Continue Reading

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.
