A case of mistaken arrhythmogenic identity during pregnancy

Clinical Case Reports, 2021
Atypical LVOT ectopy can present with an RVOT morphology on ECG and differentiation to reveal this focus is in favor of benign idiopathic ventricular ectopy over an arrhythmogenic cardiomyopathy.

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 ...

Single-cell analysis of cardiogenesis reveals basis for organ-level developmental defects. [PDF]

, 2019
Organogenesis involves integration of diverse cell types; dysregulation of cell-type-specific gene networks results in birth defects, which affect 5% of live births.

Temporal profile and mechanisms of the prompt sympathoexcitation following coronary ligation in Wistar rats [PDF]

, 2014
Our aim was to assess the timing and mechanisms of the sympathoexcitation that occurs immediately after coronary ligation. We recorded thoracic sympathetic (tSNA) and phrenic activities, heart rate (HR) and perfusion pressure in Wistar rats subjected to ...

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 ...

Malignant ventricular arrhythmias induction by programmed electrical stimulation of the right ventricular outflow tract only during type 1 brugada ECG maximization [PDF]

, 2016
OBJECTIVE: The role of electrophysiology study in Brugada syndrome (BS) sudden cardiac death risk stratification remains controversial and seems to depend on the phenotypic expression of the channelopathy.

Differentiating Right- and Left-Sided Outflow Tract Ventricular Arrhythmias.

Circulation: Arrhythmia and Electrophysiology, 2019
Idiopathic ventricular arrhythmias commonly originate from the right ventricular and left ventricular outflow tracts (OTs). Advances in real-time imaging have refined our understanding of the intimate anatomic structures implicated in the genesis of OT ...

Malignant conversion of benign right ventricular outflow track ventricular tachycardia 18 years post-ablation

Journal of Arrhythmia, 2015
This case report describes the rare phenomenon of malignant conversion of benign right ventricular outflow tract ventricular tachycardia into idiopathic ventricular fibrillation 18 years after successful ablation, in the absence of any type of heart ...
