Detecting left main coronary artery disease by apical, cross-sectional echocardiography.
To test the feasibility of imaging the left main coronary artery (LMCA) noninvasively as a means of detecting left main coronary artery disease, we studied 73 patients who underwent cardiac catheterization and cross-sectional echocardiography. Fifty-two had a normal LMCA (controls) and 21 had significant obstruction (greater than or equal to 50% luminal reduction). The apical, tomographic, cros...
متن کاملNoninvasive visualization of the left main coronary artery by cross-sectional echocardiography.
Real time cross-sectional echocardiographic studies of the left main coronary artery (LMCA) were performed in 15 normal patients, 15 patients with angiographically proven coronary artery disease but normal left main coronary segments, three patients with greater than 75% obstruction of the left main coronary artery, and one patient with a larger aneurysm of the left main coronary artery. In nor...
متن کاملNoninvasive visualization of the dilated main coronary arteries in coronary artery fistulas by cross-sectional echocardiography.
Real-time cross-sectional echocardiographic studies of the main coronary arteries were performed in 20 normal subjects, 12 patients with patent ductus arteriosus and 14 patients with coronary artery fistula in whom the diagnosis was established by angiography. In 12 patients, the coronary artery that formed the fistula was dilated: The right coronary artery was involved in eight and the left co...
متن کامل[Left main coronary artery disease].
There are many causes of left main coronary artery disease, the first of which is atherosclerosis. Other rarer causes may be observed, such as acute and chronic occlusions, spasm and primary and secondary dissection. The prevalence of stenosis of the left main coronary artery at coronary angiography is about 5%. The risk factors are the same as for coronary artery disease. The symptoms are angi...
متن کاملEvaluation of left coronary artery anatomy in vitro by cross-sectional echocardiography.
This study was undertaken to provide a better anatomic description of the location and course of the left coronary artery within a commonly used ultrasonic tomographic plane. Twenty-three hearts were excised at autopsy and scanned in vitro. The locations of the left main (LMCA), left anterior descending (LAD), and left circumflex (LCCA) coronary arteries were confirmed by direct cannulation, by...
