  2. Ventricular outflow tract - Wikipedia

    en.wikipedia.org/wiki/Ventricular_outflow_tract

    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. [1]The right ventricular outflow tract (RVOT) is an infundibular extension of the ventricular cavity that connects to the pulmonary artery.

  3. Ventricular outflow tract obstruction - Wikipedia

    en.wikipedia.org/wiki/Ventricular_outflow_tract...

    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]

  4. Ventricular tachycardia - Wikipedia

    en.wikipedia.org/wiki/Ventricular_tachycardia

    Scar-related monomorphic ventricular tachycardia is the most common type and a frequent cause of death in patients having survived a heart attack, especially if they have weak heart muscle. [12] Right ventricular outflow tract (RVOT) tachycardia is a type of monomorphic ventricular tachycardia originating in the right ventricular outflow tract ...

  5. Arrhythmogenic cardiomyopathy - Wikipedia

    en.wikipedia.org/wiki/Arrhythmogenic_cardiomyopathy

    Right ventricular outflow tract (RVOT) tachycardia is the most common VT seen in individuals with ACM. In this case, the EKG shows a left bundle branch block (LBBB) morphology with an inferior axis. Diagnosis

  6. Premature ventricular contraction - Wikipedia

    en.wikipedia.org/wiki/Premature_ventricular...

    Premature ventricular contraction usually originates from an area of Ectopic focus. In this illustration ectopic area is near papillary muscles in the left ventricle. Most commonly in healthy hearts PVCs occur near right ventricular outflow tract (RVOT). A premature ventricular contraction on an EKG, marked by the arrow: Specialty: Cardiology

  7. Shunt equation - Wikipedia

    Qp = VTI RVOT × π × (d RVOT / 2)² <=> Qp = VTI RVOT × 0.785 × d RVOT ² Qs = VTI LVOT × π × (d LVOT / 2)² <=> Qs = VTI LVOT × 0.785 × d LVOT ² Where: d RVOT - Right ventricular outflow tract diameter VTI RVOT - Velocity time integral of the right ventricular outflow tract before the pulmonary valve d LVOT - Left ventricular outflow ...

  8. Transcatheter pulmonary valve replacement - Wikipedia

    en.wikipedia.org/wiki/Transcatheter_pulmonary...

    [4] [6] Ventricular function and size are assessed with an echocardiogram. [4] The right ventricle and the anatomy of the outflow tract, including any anatomical variations, are also assessed with cardiac magnetic resonance imaging. [4] [6] The severity of the outflow tract defect or pulmonary regurgitation is assessed with Doppler ...

  9. Overriding aorta - Wikipedia

    en.wikipedia.org/wiki/Overriding_aorta

    The result is that the aorta receives some blood from the right ventricle, causing mixing of oxygenated and deoxygenated blood, and thereby reducing the amount of oxygen delivered to the tissues. It is one of the four findings in the classic tetralogy of Fallot. The other three findings are right ventricular outflow tract (RVOT) obstruction ...
