Abrupt change in the shape of a left ventricular mural thrombus after intra-aortic balloon pump-supported percutaneous coronary intervention in recent myocardial infarction.

A 77-year-old woman was diagnosed with congestive heart failure and broad anterior acute myocardial infarction that had occurred 10 days prior to her presentation in our hospital. A flat and immobile thrombus was widely attached to the luminal surface of the left ventricular antero-apical wall with dyskinetic motion. For treatment-resistant heart failure, the patient underwent percutaneous coronary intervention (PCI), with intravenous heparin, supporting an intra-aortic balloon pump.

Occlusion of left main coronary artery during percutaneous coronary intervention for chronic total occlusion of left circumflex artery with retrograde approach.

The retrograde approach, a new technique of percutaneous coronary intervention (PCI) for chronic total occlusion (CTO), allows coronary interventionalists to improve the success rate. However, this technique occasionally has serious complications. We report a case with the occlusion of left main coronary artery (LMCA) during PCI for CTO in the proximal LCX with retrograde approach because of backward spiral dissection formed by retrograde wire.

Serial angiographic findings and prognosis of stent fracture site without early restenosis after sirolimus-eluting stent implantation.

Background: Stent fracture is one of the possible causes of in-stent restenosis after sirolimus-eluting stent (SES) implantation. However, long-term prognosis including late restenosis in stent fracture site without early restenosis remains unknown. The aim of this study is to investigate the risk of late restenosis at the stent fracture site without early restenosis after SES implantation.

Predictors and prognosis of stent fracture after sirolimus-eluting stent implantation.

Background: Stent fracture is a cause of in-stent restenosis (ISR) after sirolimus-eluting stent (SES) implantation, so this study investigated the incidence, predictors and prognosis of stent fracture.

Methods And Results: The 273 consecutive patients (364 lesions) after SES implantation and who had 6-9 month' scheduled follow-up coronary angiography (CAG) were divided into groups with and without stent fracture. Deltaangle was defined as the difference in the angle in the target lesion between diastole and systole before the procedure.
