Spontaneous coronary artery dissection in a middle-aged woman with acute anterior myocardial infarction: A case report.

Rationale: Spontaneous coronary artery dissection is a highly unusual cause of acute coronary disease. It is a result of a hematoma formation within the outer third of the tunica media,with subsequent expansion leading to compression of the true lumen and resultant myocardial ischemia.

Patient Concerns: We present a case of a middle-aged woman presenting with chest pain with acute anterior myocardial infarction, who did not reveal any of the cardiovascular risk factors.

Clinical analysis of transcatheter closure of perimembranous ventricular septal defects with occluders made in China.

Background: Results of perimembranous ventricular septal defects (pmVSD) transcatheter closure have been reported in the literature mostly using a Amplatzer VSD device. However, the data of percutaneous closure of pmVSD with VSD occluder (VSD-O) made in China are still limited. We sought to analyze safety, efficacy, and follow-up results of percutaneous closure of pmVSD with VSD-O made in China.
