Case Reports
Survival after spontaneous coronary artery dissection presenting with ventricular fibrillation arrest.
Spontaneous coronary artery dissection (SCAD) is a rarely documented etiology of myocardial infarction and sudden cardiac death (SCD). We present a case of a 37-year-old non-pregnant female who presented with a left anterior descending artery (LAD) dissection complicated by ventricular fibrillation arrest. ⋯ Also, this is only the second reported case of a patient with SCAD who survived documented SCD. Our case suggests that medical management is a reasonable option in patients with single-vessel non-left main/proximal LAD artery SCAD.

The purpose of the present study was to evaluate nonocclusive radial artery injury resulting from transradial access. ⋯ In patients with previous transradial access, evidence of nonocclusive injury can be demonstrated in the segment corresponding to the sheath location. Intimal hyperplasia was present and IVUS dimensions were significantly smaller, but the vasodilatory response to spasmolytic drugs was maintained.
