Transcatheter Aortic Valve Replacement Guided by Preprocedural Simulation of Fluoroscopic Location of the Membranous Septum.

We show the virtual simulation of the fluoroscopic location of the membranous septum using preprocedural cardiac computed tomographic data sets. Recognizing the risk distance before the procedure can help individualize implantation strategy to reduce the risk of atrioventricular conduction axis damage during transcatheter aortic valve replacement.

Monomorphic Ventricular Arrhythmias in Athletes.

Ventricular arrhythmias are challenging to manage in athletes with concern for an elevated risk of sudden cardiac death (SCD) during sports competition. Monomorphic ventricular arrhythmias (MMVA), while often benign in athletes with a structurally normal heart, are also associated with a unique subset of idiopathic and malignant substrates that must be clearly defined. A comprehensive evaluation for structural and/or electrical heart disease is required in order to exclude cardiac conditions that increase risk of SCD with exercise, such as hypertrophic cardiomyopathy and arrhythmogenic right ventricular cardiomyopathy.

Optimal P2Y12 Inhibitor in Patients With ST-Segment Elevation Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention: A Network Meta-Analysis.

Objectives: The study sought to compare the clinical efficacy and safety of P2Y12 inhibitors in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous intervention (PPCI).

Background: Limited data exist regarding the comparative efficacy and safety of P2Y12 inhibitors in STEMI patients undergoing PPCI.

Methods: Clinical trials enrolling STEMI patients were identified and relevant data was extracted.
