A self-expanding percutaneous valve for patients with pulmonary regurgitation and an enlarged native right ventricular outflow tract: one-year results.

EuroIntervention, 2019
AIMS The aim of the study was to evaluate the midterm safety and efficacy of a self-expanding valve (Venus P-valve) in the treatment of patients with pulmonary regurgitation and a native right ventricular outflow tract (RVOT) in China.

Right ventricular outflow tract low‐voltage areas identify the site of origin of idiopathic ventricular arrhythmias: A high‐density mapping study

Cardiovascular Electrophysiology, 2019
Electronatomical mapping allows direct and accurate visualization of myocardial abnormalities. This study investigated whether high‐density endocardial bipolar voltage mapping of the right ventricular outflow tract (RVOT) during sinus rhythm may guide ...

Percutaneous axillary artery approach for ductal stenting in critical right ventricular outflow tract lesions in the neonatal period

Catheterization and cardiovascular interventions, 2019
We aimed to assess the experience using a percutaneous axillary artery approach for insertion of arterial ductal stents in patients with critical right ventricular outflow tract lesions at two tertiary pediatric cardiology centers.

Contegra versus pulmonary homograft for right ventricular outflow tract reconstruction in newborns

Cardiology in the Young, 2019
Objectives: Pulmonary homografts are standard alternatives to right ventricular outflow tract reconstruction in congenital heart surgery. Unfortunately, shortage and conduit failure by early calcifications and shrinking are observed for small-sized ...

Right Ventricular Outflow Tract Pacing

Pacing and Clinical Electrophysiology, 1997
“He who expresses an opinion should not voice it as correct and right but set it forth as a contribution to the consensus of opinion, for the light of reality becomes apparent when two opinions coincide. A spark is produced when flint and steel come together. Man should weigh his opinions with the utmost serenity, calmness, and composure.

Right ventricular outflow tract obstruction

2013
Congenital pulmonary valve abnormalities encompass a spectrum of anomalies that result in right ventricular outflow tract (RVOT) obstruction. Based on the level of obstruction, there are three possible variants: (a) valvular, (b) subvalvular (infundibular stenosis), and (c) supravalvular.

Right ventricular outflow tract obstruction

2014
Conditions that result in right ventricular outflow tract obstruction, i.e. valvular, supravalvular, and branch pulmonary stenosis, are discussed.

Novel use of a 3D printed heart model to guide simultaneous percutaneous repair of severe pulmonary regurgitation and right ventricular outflow tract aneurysm

Cardiology in the Young, 2019
We describe percutaneous repair of severe pulmonary regurgitation and a right ventricular outflow tract pseudoaneurysm in a 19-year-old patient after repair of pulmonary atresia, ventricular septal defect, and major aortopulmonary collaterals.

Acquired right ventricular outflow tract obstruction in twin‐to‐twin transfusion syndrome; a prospective longitudinal study

Prenatal Diagnosis, 2018
The pathophysiology of right ventricular outflow tract obstruction (RVOTO) in twin‐to‐twin transfusion syndrome (TTTS) recipients is incompletely understood. We aimed to investigate the development and spectrum of RVOTO in TTTS recipients.

Right Ventricular Dysfunction Due to Right Ventricular Outflow Tract Patch

Asian Cardiovascular and Thoracic Annals, 2006
Doppler tissue imaging analysis was used to examine the relationship between right ventricular function and right ventricular outflow tract damage in 54 patients with repaired tetralogy of Fallot. The patients were divided into three groups: 16 in whom the right ventricular outflow tract was directly sutured (group DS), 23 who had transventricular ...
