Successful calcium modification of a large calcified nodule using shockwave intravascular lithotripsy in the setting of acute coronary syndrome: a case report.

Background: Calcified nodules are associated with suboptimal preparation before stenting due to challenging crossing and unsuccessful pre-dilation and calcium cracking with conventional balloons. In this scenario, we report the use of shockwave intravascular lithotripsy for the successful lesion preparation of an undilatable and challenging calcified nodule in a patient presenting with ACS.

Case Summary: We report a case of a 79-year-old male patient presented with non-ST elevation myocardial infarction.

The role of optical coherence tomography guidance in scaffold versus stent optimization.

Background: Optical coherence tomography showed a great ability to identify adverse features during percutaneous coronary intervention with drug-eluting stents and resulted in better clinical outcomes. The study aimed to assess the impact of optical coherence tomography on intraoperative decision-making during implantation of Absorb bioresorbable scaffolds versus everolimus drug-eluting stents.

Results: We performed an observational study that included 223 consecutive patients post optical coherence tomography-guided implantation of either Absorb bioresorbable scaffolds (162 patients) or everolimus drug-eluting stents (61 patients).

Long-term outcome of first 300 implanted Absorb bioresorbable vascular scaffolds in an all-comers Middle East population.

Objectives: To evaluate long-term clinical outcomes of the Absorb bioresorbable vascular scaffold (BVS) system (Abbott Vascular) in an all-comers Middle East population.

Methods: This prospective registry study included an initial set of patients with coronary lesions treated using Absorb BVS. Patients were followed for target vessel failure (TVF) including cardiac death, target vessel myocardial infarction (MI), and target lesion revascularization.

A case of dilated cardiomyopathy and severe mitral regurgitation treated using a combined percutaneous approach of MitraClip followed by CARILLON® mitral contour system.

Functional mitral regurgitation (FMR) is common in severe heart failure. Medical therapy is the standard of care since the role of surgery is less established. Various trans-catheter percutaneous techniques may avoid the risks of surgery; such as edge-to-edge repair using MitraClip system (Abbott Vascular, Illinois, USA) and CARILLON® Mitral Contour System® (Model XE2; Cardiac Dimensions.
