Spontaneous coronary artery dissection: prevalence of predisposing conditions including fibromuscular dysplasia in a tertiary center cohort.
We sought to evaluate the prevalence of fibromuscular dysplasia (FMD) and other predisposing conditions among spontaneous coronary artery dissection (SCAD) patients. ⋯ Nonatherosclerotic SCAD predominantly affects women, and most have concomitant FMD. We suspect these patients have underlying coronary FMD that predisposed them to SCAD, but this requires proof from histology or intracoronary imaging of the affected coronary arteries.

Intra-procedural stent thrombosis: a new risk factor for adverse outcomes in patients undergoing percutaneous coronary intervention for acute coronary syndromes.
The aim of this study was to examine the incidence, correlates, and consequences of intra-procedural stent thrombosis (IPST) in patients with acute coronary syndromes (ACS). ⋯ Intra-procedural ST is a relatively rare complication of PCI in ACS but is strongly associated with subsequent out-of-lab ST and mortality. Intra-procedural ST should be considered as a distinct category of ST and routinely reported, particularly for ACS patients.

Percutaneous transcatheter aortic valve closure successfully treats left ventricular assist device-associated aortic insufficiency and improves cardiac hemodynamics.
This study sought to assess the effectiveness of a novel percutaneous method to treat left ventricular assist device (LVAD)-associated severe aortic insufficiency (AI) in a series of patients determined to be poor reoperative candidates. ⋯ Percutaneous transcatheter closure of the aortic valve effectively treats LVAD-associated AI and reduces pulmonary capillary wedge pressure. This procedure should be considered to treat LVAD-associated AI in patients who are poor candidates for repeat operation. Further data are needed to assess long-term results.
