Spontaneous left main coronary artery spasm and intravascular ultrasonography findings
Vasospasm causes an abrupt and temporary occlusion in coronary arteries in patients with normal coronary arteries. Nonetheless, vasospasm of the left main coronary artery is unusual and can be spontaneous or iatrogenic. We herein report a very rare cause of temporary spasm of LMCA, which resulted in vasospastic angina and anginal chest pain. Intravascular ultrasonography should be considered as...
متن کاملThe Changing Face of First-Year Intravascular Ultrasonography in Heart Transplantation.
I n this issue of JACC: Heart Failure, Okada et al. (1) demonstrate paradoxical vessel remodeling of the proximal left anterior descending (LAD) coronary artery segment at 1 year to be predictive of long-term mortality in a cohort of 100 heart transplantation patients. The authors are to be congratulated in pursuing the arduous task of assessing and analyzing intravascular ultrasonography (IVUS...
متن کاملAcute myocardial infarction caused by myocardial bridging alone confirmed by using intravascular ultrasonography
Although the underlying pathogenesis of acute myocardial infarction (AMI) caused by myocardial bridging (MB) is not fully understood, high shear stress that induces endothelial dysfunction or damage that leads to thrombus formation has been mainly considered. We report a case of AMI due to MB confirmed in a series of angiographic examinations, including intravascular ultrasonography (IVUS). Our...
متن کاملIntravascular epithelioid hemangioendothelioma of the femoral vein diagnosed by contrast-enhanced ultrasonography
RATIONALE Intravascular epithelioid hemangioendothelioma (EHE) is a rare endothelial tumor with an intermediate grade of malignancy. We present a case of one woman affected by EHE of the femoral vein. Contrast-enhanced ultrasonography played a role in diagnosing EHE and helped differentiate it from thrombosis. To our knowledge, this is the first reported contrast-enhanced ultrasonography of int...
متن کاملRecanalization of an Accidentally Crushed Coronary Stent by Intravascular Ultrasonography Catheter Entrapment
Intravascular ultrasonography (IVUS) imaging is a user-friendly technique widely used during coronary interventions. An 80-year-old man was admitted with chest pain, and successful percutaneous coronary intervention was performed with stent implantation. One week later, the patient complained of further chest pain. Urgent coronary angiography showed total occlusion of the middle left anterior d...
