Background: Balloon non-crossable stenoses represent a challenging subset of coronary artery disease (CAD). They are clinically associated with patients who are older, frailer, and with multi-morbidities, and angiographically with increased tortuosity and coronary artery calcification. Combined rotational (RA) excimer laser coronary atherectomy (ELCA), or RASER, may facilitate stent delivery and deployment in non-crossable, non-dilatable severely calcified lesions.

Intravascular lithotripsy (IVL) and rotational atherectomy (RA) are safe and effective methods of treating coronary calcification in the non-LMCA setting. This retrospective analysis assessed the feasibility of IVL versus RA in unprotected LMCA disease.
View Article and Find Full Text PDFIn-stent restenosis (ISR) has always been considered a conundrum for interventional cardiologists. Despite many technical advances in the past 20 years aimed at reducing its occurrence, this area of interventional cardiology remains challenging. Here, we present a novel use of intravascular lithotripsy therapy (IVL) in a patient with repeat ISR, in whom IVL treatment has provided excellent procedural and follow-up results.

Method: A retrospective analysis of prospectively collected data on all under-expanded, under-deployed stents that were managed by excimer laser, with and without contrast, performed at the Freeman Hospital, a large tertiary cardiac center, in the northeast of England.
Acute ST segment elevation myocardial infarction (STEMI) is characterized by complete thrombotic occlusion of a major coronary artery. Early recanalization of the infarct-related artery is most efficiently delivered by primary percutaneous coronary intervention (PPCI), however this does not always restore normal myocardial perfusion, mainly due to distal embolization of the thrombus and microvascular obstruction. Early evidence for manual thrombus aspiration during PPCI was promising and this was once considered an important aspect of the procedure, especially in patients with a high thrombus burden.

Unlabelled: Early identification of higher risk patients presenting with ST-elevation myocardial infarction (STEMI) and undergoing primary percutaneous coronary intervention (PPCI) will allow a more aggressive strategy and approach. The aim of this study was to evaluate the shock index (ratio of heart rate/systolic blood pressure on admission) as a predictor of mortality post PPCI in addition to other parameters.
Methods: We analysed prospectively collected data on 3049 STEMI patients treated with PPCI in a large tertiary centre between March 2008-December 2011, out of which 2424 patients were aged up to 75 years (young) and 625 patients were older than 75 years (elderly).
Background: Gastrointestinal (GI) bleeding following percutaneous coronary intervention (PCI) is associated with increased mortality. ACCF/AHA/SCAI guidelines recommend prophylaxis to prevent GI bleeding in patients, with the highest GI bleeding risks taking dual-antiplatelet therapy (DAPT). The REPLACE risk score identifies factors predictive of peri-PCI bleeding from vascular access and non-access sites.
