Mid-Ventricular Ballooning in Atherosclerotic and Non-Atherosclerotic Abnormalities of the Left Anterior Descending Coronary Artery

Stefan Peters*

Published: 30 December, 2016 | Volume 1 - Issue 1 | Pages:

In a series of meanwhile 10 cases rigid straightening of the mid-portion of the left anterior descending coronary artery without lumen reduction mid-ventricular or basal ballooning was reported, or both basal and mid-ventricular ballooning in one case. In all these patients wrap-around (recurrent segment) phenomenon of the left anterior descending coronary artery was not present. The abnormalities of the left anterior descending coronary artery are due to myocardial bridging without lumen reduction of the LAD, only seen in computed tomography. When stress or in some cases happiness appears myocardial ballooning can appear, lasts 2-4 weeks and disappear with a recurrence rate of nearly 10% despite beta blocking agents.
