The case of an asymptomatic patient with prolapsing left atrial myxoma, in whom preoperative coronary angiography revealed a rare coronary artery anatomy in the absence of atherosclerotic obstructive disease, is presented. There was a type IV dual left anterior descending (LAD) artery with intraseptal course of the right aortic sinus-connected (long) LAD artery and an ectopic left circumflex artery...
Isolated right ventricular infarction (RVI) is an increasingly recognized cause of precordial ST-segment elevation (STE). A patient is described who developed STE in leads V1–V5 secondary to occlusion of the right ventricular branch during stent angioplasty to the right coronary artery. The pattern of precordial STE was thought to be suggestive of anteroseptal myocardial infarction because of progressive...
Motion of the carotid atheromatous plaque may be responsible for plaque rupture and cerebrovascular symptoms. B-mode ultrasound allows non-invasive recording of arterial wall and plaque motion. Our aim was to analyze quantitatively patterns of arterial wall motion with different techniques. Temporal sequences of digitized B-mode ultrasound images of the carotid arteries of 10 young healthy subjects...
