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 ...

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 ...

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 ...

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 ...

Apical ballooning syndrome complicated by acute severe mitral regurgitation with left ventricular outflow obstruction – Case report

Journal of Cardiothoracic Surgery, 2007
Background Apical ballooning syndrome (or Takotsubo cardiomyopathy) is a syndrome of transient left ventricular apical ballooning. Although first described in Japanese patients, it is now well reported in the Caucasian population. The syndrome mimicks an

Undiagnosed hypertrophic obstructive cardiomyopathy during transcatheter aortic valve replacement: a case report

Journal of Medical Case Reports, 2018
Background Transcatheter aortic valve replacement is indicated for severe symptomatic aortic stenosis in patients who have a very high or prohibitive surgical risk as assessed pre-procedurally by the Society of Thoracic Surgery Risk Score, EuroSCORE (II),

Transient dynamic left ventricular outflow tract obstruction

Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2017
Dynamic left ventricular outflow (LVOT) obstruction has been classically described in patients with hypertrophic cardiomyopathy (HCM). The hypertrophy of the basal septum and systolic anterior motion of the mitral valve leaflet (SAM) cause dynamic LVOT ...

Impact of VA-ECMO on Dynamic LV Outflow Obstruction After Transcatheter Aortic Valve Replacement

JACC: Case Reports
Dynamic left ventricular outflow obstruction is a rare but severe complication of transcatheter aortic valve replacement. It presents as a paradoxical hemodynamic collapse after relieving the left ventricular afterload.
