Antegrade Intentional Laceration of the Anterior Mitral Leaflet to Prevent Left Ventricular Outflow Tract Obstruction

Circulation. Cardiovascular Interventions, 2020
Background: Intentional laceration of the anterior mitral leaflet (LAMPOON) is an effective adjunct to transcatheter mitral valve replacement that prevents left ventricular outflow tract (LVOT) obstruction. To date, LAMPOON has been performed in over 150

Dynamic left ventricular outflow tract obstruction: underestimated cause of hypotension and hemodynamic instability

Journal of Ultrasonography, 2014
Left ventricular outflow tract obstruction, which is typically associated with hypertrophic cardiomyopathy, is the third most frequent cause of unexplained hypotension. This underestimated problem may temporarily accompany various diseases (it is found

Patient-specific fluid simulation of transcatheter mitral valve replacement in mitral annulus calcification

Frontiers in Cardiovascular Medicine, 2022
IntroductionTranscatheter mitral valve replacement is a promising alternative to open-heart surgery in elderly patients. Patients with severe mitral annulus calcification (MAC) are a particularly high-risk population, where postprocedural complications ...

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 ...

Right ventricular outflow tract obstruction in an infant [PDF]

Heart, 2005
A 3 month old, asymptomatic infant with tuberous sclerosis and multiple intracardiac tumours that were diagnosed prenatally (panel A) underwent surgery for resection of a large tumour (1.3 × 0.8 × 0.7 cm) obstructing the right ventricular outflow tract (RVOT) (panel B). After birth …

Giant Cardiac Rhabdomyoma with Mixed Atrial Tachycardia and Nonsustained Ventricular Tachycardia in a Newborn with Tuberous Sclerosis

The Ewha Medical Journal, 2022
Cardiac rhabdomyomas are typically presented in the tuberous sclerosis. Although benign and often associated with spontaneous regression, in rare circumstances huge mass size and critical location can lead to heart failure, ventricular outflow tract ...

Comprehensive left ventricular outflow tract management beyond septal reduction to relieve obstruction

Asian Cardiovascular and Thoracic Annals, 2021
The surgical management of patients with hypertrophic obstructive cardiomyopathy can be extremely challenging. Relieving the left ventricular outflow tract obstruction in these patients is often achieved by performing a septal myectomy.

Conventional cardiopulmonary resuscitation-induced refractory cardiac arrest due to latent left ventricular outflow tract obstruction due to a sigmoid septum: a case report

Journal of Medical Case Reports, 2018
Background Patients with left ventricular outflow tract obstruction who do not exhibit a dynamic pressure gradient at rest, experience pressure gradient increases of ≥ 30 mmHg only during specific situations; this is called latent left ventricular ...

A companion to the preclinical common data elements and case report forms for in vivo rodent neuroimaging: A report of the TASK3‐WG3 Neuroimaging Working Group of the ILAE/AES Joint Translational Task Force

Epilepsia Open, EarlyView., 2022
Abstract The International League Against Epilepsy/American Epilepsy Society (ILAE/AES) Joint Translational Task Force established the TASK3 working groups to create common data elements (CDEs) for various aspects of preclinical epilepsy research studies, which could help improve the standardization of experimental designs.

On the Cardiac Loop and Its Failing: Left Ventricular Outflow Tract Obstruction

Journal of the American Heart Association : Cardiovascular and Cerebrovascular Disease, 2020
V iewed dispassionately, the cardiac loop seems an unconventional, even an odd, evolutionary adaptation. The ventricular U-turn loop, which occurs in all reptiles, mammals, and birds, forces blood to travel back on itself with a 180° turn between the ...
