Sudden failure of ventricular pacing and recovery in a patient with cardiac sarcoidosis

Journal of Arrhythmia, 2017
A 76-year-old woman with sarcoidosis who had an implantable pacemaker for complete atrioventricular block was admitted with syncope. Electrocardiogram revealed ventricular pacing failure, and a marked rise in the ventricular pacing threshold.

Size of atrial septal defect after balloon atrial septostomy does not correlate with immediate improvement in oxygenation

World Journal of Pediatric Surgery, 2021
Objective Transposition of great arteries is a common cyanotic heart defect. Balloon atrial septostomy aims to improve circulatory mixing and oxygenation.

Nonischemic left ventricular scar and cardiac sudden death in the young [PDF]

, 2016
Nonischemic Left Ventricular Scar (NLVS) is a pattern of myocardial injury characterized by midventricular and/or subepicardial gadolinium hyper enhancement at cardiac magnetic resonance, in absence of significant coronary artery disease.

Halo-shape technique for leadless pacemaker implantations: A case report

Indian Pacing and Electrophysiology Journal, 2021
A 92-year-old woman underwent an implantation of a leadless pacemaker (Micra; Medtronic, Inc, Minneapolis, MN) for complete atrioventricular block after a transvenous lead extraction due to a pocket infection of a dual chamber pacemaker. Marked scoliosis

Common arterial trunk with intact septum and hypoplastic right ventricle: An uncommon embryological entity

Annals of Pediatric Cardiology, 2020
Embryologically, the common arterial trunk (CAT) is due to the failure of septation by the major outflow cushions. This invariably leads to the presence of an associated large juxta-arterial ventricular septal defect. Overriding of the ventricular septum

Compensated right ventricular function of the onset of pulmonary hypertension in a rat model depends on chamber remodeling and contractile augmentation. [PDF]

, 2018
Right-ventricular function is a good indicator of pulmonary arterial hypertension (PAH) prognosis; however, how the right ventricle (RV) adapts to the pressure overload is not well understood.

Changes in left atrial deformation in hypertrophic cardiomyopathy: Evaluation by vector velocity imaging. [PDF]

, 2012
OBJECTIVES: Hypertrophic cardiomyopathy (HCM) represents a generalized myopathic process affecting both ventricular and atrial myocardium. We assessed the global and regional left atrial (LA) function and its relation to left ventricular (LV) mechanics ...
