Leadless pacing with Micra TPS: A comparison between right ventricular outflow tract, mid‐septal, and apical implant sites

Cardiovascular Electrophysiology, 2019
With its steerable transcatheter delivery system, the Micra can be deployed in nonapical positions within the right ventricle, potentially allowing reduction of the paced QRS width.

Physiological and clinical consequences of relief of right ventricular outflow tract obstruction late after repair of congenital heart defects. [PDF]

, 2006
BACKGROUND: Right ventricular outflow tract obstruction (RVOTO) is a common problem after repair of congenital heart disease. Percutaneous pulmonary valve implantation (PPVI) can treat this condition without consequent pulmonary regurgitation or ...

Catheter ablation of right ventricular outflow tract tachycardia using contact force guidance [PDF]

, 2014
Outflow tract tachycardias (OTT) originating from the right or left ventricular outflow tract are thought to be benign. However, symptoms can be disabling and deterioration of left ventricular function may occur with a high arrhythmia burden.

Modern mapping and ablation of idiopathic outflow tract ventricular arrhythmias

Reviews in Cardiovascular Medicine, 2022
Outflow tract (OT) premature ventricular complexes (PVCs) are being recognized as a common and often troubling, clinical electrocardiographic finding. The OT areas consist of the Right Ventricular Outflow Tract (RVOT), the Left Ventricular Outflow Tract (

First human implant of the Alterra Adaptive PrestentTM: A new self‐expanding device designed to remodel the right ventricular outflow tract

Catheterization and cardiovascular interventions, 2018
Current balloon expandable transcatheter valves have limited applicability to patients with “native” right ventricular outflow tracts (RVOT), meaning those who have had previous surgery and are left with large, compliant, irregular RVOT.

Myocardial deletion of Smad4 using a novel alpha skeletal muscle actin Cre recombinase transgenic mouse causes misalignment of the cardiac outflow tract [PDF]

, 2010
S MAD4 acts as the converging point f or T GF β and BMP signaling in heart development. Here, we investigated the role of S MAD4 in heart development usi ng a novel α skeletal muscle actin Cre recombinase (MuCre) transgenic mouse strain.

Isolated right ventricular outflow obstruction: A unique phenotype of hypertrophic cardiomyopathy with review of literature

IHJ Cardiovascular Case Reports, 2019
Biventricular outflow obstruction in hypertrophic cardiomyopathy is an uncommon phenotype. A rare variant is that with isolated right ventricular outflow obstruction without resting or provocable pressure gradients within the left ventricular cavity.
