Simplified mapping and ablation of a scar-related atrial tachycardia using magnetic resonance imaging tissue characterization.

We present a case of a magnetic resonance imaging-assisted ablation of an atrial tachycardia in a patient with previous atrial fibrillation ablation. A 3-D reconstruction of the delayed-enhanced cardiac magnetic resonance (CMR; CMR model) was created to identify previous ablation lesions and gaps. Multiple gaps around right-sided pulmonary veins were observed. The activation map identified a dual-loop re-entry around both right-sided pulmonary veins, confirming that the substrate identified using delayed-enhanced CMR was critical to sustain the tachycardia. Ablation at this site converted to sinus rhythm. The present case shows the usefulness of delayed-enhanced CMR substrate characterization to complement activation mapping of the tachycardia and more accurately define the anatomical circuit. 

Left atrial tachycardia after atrial fibrillation ablation: can magnetic resonance imaging assist the ablation?

Ventricular Tachycardia: Inferior Vena Cava Filter in a Case of Peripheral Vascular Disease.

In high-risk patients with severe aortic stenosis, aortic valve replacement (AVR) with a sutureless Perceval prosthesis (SU-AVR) can be performed instead of conventional AVR or transcatheter aortic valve implantation. Little data are available regarding postoperative conduction disorders after SU-AVR. We aimed to determine the incidence and predictors of new-onset complete atrioventricular block (NO-AVB) requiring permanent cardiac stimulation following SU-AVR.

Atrial dysfunction has been widely considered a marker or consequence of other cardiac conditions rather than the cause itself. Here, we propose the term atrial failure as a clinically relevant entity, defined as any atrial dysfunction causing impaired heart performance, symptoms, and worsening quality of life or life expectancy. Aspects of the etiology, mechanisms, and consequences of atrial failure are discussed. Recent advances in cardiac electrophysiology and imaging have improved our understanding of the highly complex atrial anatomy and function, underlying the paramount importance of the atria in optimal heart performance. It is time to reappraise the concept of the failing atrium as a primary cause or aggravating factor of the symptoms in many of our patients. The concept of atrial failure may foster basic and translational research to gain a better understanding of how to identify and manage atrial dysfunction.

Atrial Failure as a Clinical Entity: JACC Review Topic of the Week.

This study sought to analyze safety and outcomes of ventricular tachycardia (VT) substrate ablation during sinus rhythm (SR), without baseline VT induction.

Safety and Outcomes of Ventricular Tachycardia Substrate Ablation During Sinus Rhythm: A Prospective Multicenter Registry.

Up to one-third of patients who undergo cardiac resynchronization therapy do not obtain clinical benefit. A systematic approach can identify treatable causes in many nonresponding patients. We present a case of nonresponse to cardiac resynchronization therapy that resolved by ablation of the atrioventricular node in a patient with complete atrioventricular block. ().
