Physiology of slow pathway conduction during sinus rhythm: evidence from high density mapping within the triangle of Koch.

Purpose: To evaluate nature of AV nodal activation in patients with AVNRT using high density electro-anatomic mapping (HD-EAM).

Methods: HD-EAM was created in 30 patients with AVNRT from the triangle of Koch (ToK) in sinus rhythm (SR). Isochronal late activation maps (ILAM) were created.

Syncope After Transcatheter Aortic Valve Replacement: Two Faces of Abnormal Intraventricular Conduction.

Conduction system damage is the most common complication of transcatheter aortic valve replacement (TAVR), which frequently requires placement of a permanent pacemaker. Bundle branch reentry (BBR) is a well-recognized mechanism of ventricular tachycardia (VT) in the setting of abnormal intraventricular conduction. We describe a case of a patient with post-TAVR intraventricular conduction abnormalities who presented with intermittent advanced atrioventricular block and BBR VT and discuss the potential risks, diagnosis, and management of BBR after TAVR.

Non-vitamin K antagonists oral anticoagulants are as safe and effective as warfarin for cardioversion of atrial fibrillation: A systematic review and meta-analysis.

Background: Current guidelines recommend anticoagulation using warfarin with bridging parenteral anticoagulation or one of the non-vitamin K antagonist oral anticoagulants (NOACs) to prevent thromboembolic events in patients undergoing cardioversion for atrial fibrillation (AF). We aimed to compare by meta-analytical techniques, the safety and efficacy of NOACs versus warfarin in patients undergoing cardioversion.

Methods: PUBMED, EMBASE, Cochrane CENTRAL and CINAHL were searched electronically in addition to manual search for randomized controlled trials (RCTs) comparing NOACs and warfarin in patients undergoing cardioversion for AF.

Single Stage Repair of Aortic Coarctation and Coronary Artery Bypass Grafting in a 55-Year- Old-Man Presenting with Pulmonary Edema.

Coarctation of the aorta, virtually always a congenital malformation, is characterized by localized aortic narrowing, usually in the arch opposite to the ductus arteriosus and just distal to the left subclavian artery. The condition occasionally goes undiagnosed until adulthood. We report a case of a 55-year-old man who presented with uncontrolled hypertension, pulmonary edema, and non-ST-segment elevation myocardial infarction due to multi-vessel coronary artery disease.

Aspiration thrombectomy in a case of acute myocardial infarction due to coronary emboli in a patient with peripartum cardiomyopathy and mural thrombus.

Acute coronary syndrome (ACS) due to embolic phenomenon in the setting of peripartum cardiomyopathy (PPCM) and left ventricular mural thrombus is a rare occurrence. There have been two known cases described in medical literature. We present a unique case in which catheter-based aspiration thrombectomy was used to successfully treat a patient with ACS due to coronary emboli in the setting of PPCMand left ventricular mural thrombus.
