Right ventricular outflow tract obstruction (RVOTO) is a cause of hemodynamic instability that can occur in several situations, including cardiac surgery, lung transplantation, and thoracic surgery, and in critically ill patients.

A ventricular outflow tract obstruction is a heart condition in which either the right or left ventricular outflow tract is blocked or obstructed. These obstructions represent a spectrum of disorders. Majority of these cases are congenital, but some are acquired throughout life. [1]

Right ventricular outflow tract obstruction (RVOTO) is a rare cause of hemodynamic instability in the intensive care unit (ICU) after cardiac surgery. We report the first cases of RVOTO diagnosed in the ICU using continuous right ventricular pressure waveform monitoring.

Carries blood out of the ventricle in an anterior-superior direction. The RVOT is an important anatomical feature in many corrective surgeries for congenital heart defects and dilation of the RVOT can cause pulmonary valve insufficiency.

Apr 24, 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 …

Oct 8, 2024 · Right ventricular outflow tract (RVOT) tachycardia is a form of monomorphic VT originating from the outflow tract of the right ventricle or occasionally from the tricuspid annulus. It is usually seen in patients without underlying structural heart disease. The majority (80%) of outflow tract ventricular arrhythmias (OTVAs) originate from the RVOT.

Sep 1, 2021 · Right ventricular outflow tract obstruction (RVOTO) is a cause of hemodynamic instability that can occur in several situations, including cardiac surgery, lung transplantation, and thoracic surgery, and in critically ill patients.

Dec 10, 2024 · Right ventricular outflow tract obstruction may be caused by defects of the pulmonary valve, adjacent parts of the right ventricle, and main pulmonary artery that cause obstruction of the outflow of blood from the right ventricle. 1. Classification:

the RVOTO/PS, not the VSD) • The louder the and the shorter the murmur, the more severe the RVOT obstruction 21. Clinical Presentation • 2/3 of newborns with TOF are acyanotic at birth • By 6 months of age, over 50% will have desaturations at rest

Feb 9, 2022 · A right ventricular outflow tract obstruction (RVOTO) refers to any form of obstruction exerting effects on the right ventricular outflow tract. The obstruction itself however can occur at various sites inclusive of the following levels: mid-right ventricle; infundibulum (e.g. tetralogy of Fallot) pulmonary valve (PV) supravalvular region
