Transjugular Approach for Evoque Transcatheter Tricuspid Valve Replacement in Patients With Challenging Anatomy.

Background: The Evoque system is the first commercially available transcatheter tricuspid valve replacement (TTVR) system in the United States. However, challenging anatomy in real-world patients could preclude successful transfemoral Evoque TTVR. We aim to investigate the feasibility of the transjugular Evoque TTVR in anatomy unsuitable for a transfemoral approach.

Atrioventricular Block After EVOQUE Transcatheter Tricuspid Valve Replacement.

•Based on a real-world study of 106 Evoque transcatheter tricuspid valve replacement (TTVR) recipients, a total of 14 (25%) cases of new atrioventricular (AV) block occurred after Evoque implantation in the 55 patients without prior pacemakers who met study inclusion criteria. This incidence is similar to that reported in the TRISCEND II clinical trial.•New AV block occurred in a median of 26 hours after Evoque TTVR (interquartile range: 5-60 hours), but there were cases of new AV block that occurred as late as 7 days after the procedure.

Relative Contribution of Atrial Fibrillation to Outcomes of Patients With Cardiomyopathy Based on Severity of Left Ventricular Dysfunction.

In patients with left ventricular (LV) dysfunction, the risk of death or heart failure hospitalizations (HFHs) increases with worsening ejection fraction (EF). Whether the relative contribution of atrial fibrillation (AF) to outcomes is more pronounced in patients with worse EF is not confirmed. The present study aimed to investigate the relative influence of AF on the outcome of cardiomyopathy patients by severity of LV dysfunction.

Ventricular pacing and myocardial function in patient with congenital heart block.

Introduction: Pacing-induced cardiomyopathy (PICM) is a potential complication of chronic right ventricular (RV) pacing, but its characterization in adult patients is often complicated by pre-existing cardiomyopathy. This study investigated the incidence of PICM in patients with congenital heart block (cHB) who have conduction disease from birth without confounding pre-existing cardiac conditions.

Methods And Results: This retrospective cohort analysis included 42 patients with cHB and baseline left ventricular ejection fraction (LVEF) ≥50%.

Noninvasive imaging of peripheral nerves.

Recent developments in the field of peripheral nerve imaging extend the capabilities of imaging modalities to assist in the diagnosis and treatment of patients with peripheral nerve maladies. Methods such as magnetic resonance imaging (MRI) and its derivative diffusion tensor imaging (DTI), ultrasound (US) and positron emission tomography (PET) are capable of assessing nerve structure and function following injury and relating the state of the nerve to electrophysiological and histological analysis. Of the imaging methods surveyed here, each offered unique and interesting advantages related to the field.
