Dynamic Left Ventricular Outflow Tract Obstruction Exacerbated by Thoracic Kyphosis [PDF]
JACC: Case Reports, 2023 We present a 74-year-old woman with kyphosis and symptoms of pre/syncope. Heart catheterization revealed dynamic left ventricular outflow tract obstruction (DLVOTO) with Brockenbrough Braunwald response only when kyphotic posture was assumed.

Unstable angina complicated with dynamic left ventricular outflow tract obstruction. [PDF]
J Cardiol Cases, 2021 Left ventricular outflow tract obstruction (LVOTO) complicated with unstable angina (uAP) has not been described widely, but patients with these two conditions have several problems. Differentiation of the two conditions is also often difficult because the chest symptoms are similar.

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 ...

Dynamic Left Ventricular Outflow Tract Obstruction Post-Transcatheter Aortic Valve Replacement. [PDF]
JACC Case Rep, 2021 We describe the first case of successful management of left ventricular outflow tract obstruction developing late after transcatheter aortic valve replacement with right ventricular apical pacing. The possible mechanisms of obstruction resolution are described. (Level of Difficulty: Advanced.).

Cardiogenic Shock Secondary to Dynamic Left Ventricular Outflow Tract Obstruction and Apical Ballooning after Nonmitral Cardiovascular Surgery [PDF]
Case Reports in Critical Care, 2020 Background. The dynamic obstruction of the left ventricular outflow tract (LVOT) is a well-known complication in mitral annuloplasty but rarely seen in nonmitral cardiovascular surgery.

Dynamic left ventricular outflow tract obstruction induced by intra-aortic balloon pump in patient with angioedema [PDF]
The Ultrasound JournalBackground Intra-aortic balloon pump is used for temporary mechanical support of failing left ventricle. It works by reducing the arterial afterload during ventricular systole to reduce myocardial work and increasing diastolic proximal aortic pressure to

Anomalous Papillary Muscle Insertion Causing Dynamic Left Ventricular Outflow Tract Obstruction without Hypertrophic Obstructive Cardiomyopathy [PDF]
Case Reports in Cardiology, 2017 Anomalous papillary muscle insertion directly into the surface of the mitral valve leaflet is rare, especially in a subject without apparent evidence of hypertrophic cardiomyopathy. We present a case of this isolated congenital malformation producing two

Dynamic left ventricular outflow tract obstruction complicated with takotsubo cardiomyopathy: The acute phase of takotsubo cardiomyopathy manifests latent left ventricular outflow tract obstruction. [PDF]
J Cardiol Cases, 2018 Dynamic left ventricular (LV) outflow tract (LVOT) obstruction is sometimes complicated with takotsubo cardiomyopathy (TC). The present case involves a 70-year-old woman with chest discomfort. Seven years earlier, transthoracic echocardiography revealed LVOT obstruction due to a sigmoid-shaped septum.
