Article Synopsis
- This study examined the myocardial strain differences in patients with aortic stenosis (AS) who have normal left ventricular ejection fraction (LVEF) using advanced echocardiography techniques.
- Researchers analyzed strain patterns in subendocardial and subepicardial layers of the heart in both control subjects and AS patients, focusing on various strain types (radial, circumferential, and longitudinal).
- Results showed that while circumferential and epicardial radial strains were similar between groups, patients with AS exhibited significantly lower longitudinal and endocardial radial strains, indicating impaired myocardial function despite normal LVEF.
Spontaneous coronary dissection is a rare cause of myocardial ischemia, myocardial infarction, and sudden death. In the present case, we performed stenting only of the severe stenotic lesion of the dissection with a short bare metal stent, and left the remaining long length of dissection vessel untreated. Six months after coronary stenting, follow-up angiography revealed complete healing of the coronary dissection and no significant in-stent restenosis.

For management of the acute myocardial infarction (AMI), urgent reperfusion therapy was successfully performed through the left anterior descending coronary artery. Thereafter, no complication associated with AMI occurred.
