Triple left ventricular outflow tract obstruction [PDF]

European Heart Journal - Cardiovascular Imaging, 2011
A 59-year-old man had, over a period of 5 years, three different clinical scenarios which led to dynamic left ventricular outflow tract obstruction (LVOTO). Initially, this man who suffered from hypertrophic cardiomyopathy presented with asymmetric septal hypertrophy and systolic anterior motion (SAM) of the anterior mitral leaflet, along with mitral ...

Three-dimensional echocardiography and 2D-3D speckle tracking imaging in chronic pulmonary hypertension. diagnostic accuracy in detecting hemodynamic signs of RV failure [PDF]

, 2015
Background and objective. Our aim was to compare three-dimensional (3D) and 2D and 3D speckle tracking (2D-STE, 3D-STE) echocardiographic parameters with conventional right ventricular (RV) indexes in patients with chronic pulmonary hypertension (PH ...

Electroanatomic and Pathologic Right Ventricular Outflow Tract Abnormalities in Patients With Brugada Syndrome.

Journal of the American College of Cardiology, 2018
BACKGROUND The prevalence and significance of structural abnormalities in Brugada syndrome (BrS) are still largely debated. OBJECTIVES The authors investigated the relationship between genetic background, electroanatomic abnormalities, and pathologic ...

Acquired right ventricular outflow tract obstruction [PDF]

American Heart Journal, 1971
It is not unusual for complicated aneurysms of the ascending aorta to affect left ventricular function. Processes causing or associated with an aneurysm may narrow the coronary artery ostia and produce myocardial ischemia or infarction; the aneurysm may distort the aortic valve ring and produce aortic insufficiency with subsequent left ventricular ...

Left ventricular outflow tract velocity time integral in hospitalized heart failure with preserved ejection fraction

ESC Heart Failure, 2019
The prognostic implication of left ventricular outflow tract velocity time integral (LVOT‐VTI) on admission in hospitalized heart failure with preserved ejection fraction (HFpEF) patients has not been determined. We sought to investigate whether LVOT‐VTI

Circulation. Cardiovascular Interventions, 2018
Background— Self-expandable percutaneous pulmonary valve implantation (PPVI) for native right ventricular outflow tract lesions is still in the clinical trial phase.

Intravascular Lithotripsy for Severe RVOT Calcification to Optimize Transcatheter Pulmonary Valve Replacement

JACC: Case Reports, 2023
The presence of severe right ventricular outflow tract calcification may preclude safe and effective transcatheter pulmonary valve replacement in patients with pulmonary allograft stenosis owing to the risk of conduit tear and suboptimal annular ...

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.

Development and Morphology of the Ventricular Outflow Tracts. [PDF]

, 2016
It is customary, at the current time, to consider many, if not most, of the lesions involving the ventricular outflow tract in terms of conotruncal malformations.

Right Ventricular Outflow Tract Reconstruction in Truncus Arteriosus: A 30-Year Two-Center Comparison between Homografts and Bovine Jugular Vein

Brazilian Journal of Cardiovascular Surgery, 2023
Introduction: Homografts and bovine jugular vein are the most commonly used conduits for right ventricular outflow tract reconstruction at the time of primary repair of truncus arteriosus.
