A ventricular outflow tract is a portion of either the left ventricle or right ventricle of the heart through which blood passes in order to enter the great arteries.
The right ventricular outflow tract (RVOT) is an infundibular extension of the ventricular cavity which connects to the pulmonary artery. The left ventricular outflow tract (LVOT), which connects to the aorta, is nearly indistinguishable from the rest of the ventricle. The outflow tract is derived from the secondary heart field, during cardiogenesis.
A form of ventricular tachycardia originating from this anatomical structure is called RVOT tachycardia.
The RVOT is pathophysiologically affected in Brugada syndrome.[1]

- Rationale: In patients with Brugada syndrome, arrhythmias typically originate in the right ventricular outflow tract (RVOT). The RVOT develops from the slowly conducting embryonic outflow tract. Objective: We hypothesize that this embryonic phenotype is maintained in the fetal and adult RVOT and lea

- BACKGROUND: As the proportion of elderly population increases rapidly, it might be difficult to differentiate physiological changes in cardiac function due to age from the pathophysiological ones. In addition, cardiac function variations with gender are well established. The right ventricular (RV) p

- BACKGROUND: Even though chronic pulmonary hypertension (cPH) and acute pulmonary embolism (aPE) increase pulmonary vascular resistance and result in right ventricular (RV) dilatation and systolic dysfunction; both conditions operate through drastically different mechanisms.
