Worsening Heart Failure From Decreased Atrioventricular Synchronization Rate of a Leadless Pacemaker

JACC: Case Reports
Background: Atrioventricular synchronous pacing with a leadless pacemaker is a therapy used in patients with atrioventricular block. However, atrial oversensing may cause an increase in heart rate, with resulting atrioventricular dyssynchrony.

Late recovery of sinus rhythm following perioperative complete atrioventricular block in a child with congenitally corrected transposition

Annals of Pediatric Cardiology, 2018
We report a patient with l-transposition of the great arteries who developed perioperative complete atrioventricular block at 5 years of age in conjunction with a modified double-switch operation, but had unexpected late recovery of normal sinus rhythm ...

Radiofrequency Catheter Ablation of Atrioventricular Nodal Reentrant Tachycardia: It Is Not Always As It Is Expected [PDF]

, 2004
Observation of Coincident arrhythmias is not uncommon but the co-existence of idiopathic verapamil sensitive left ventricular tachycardia (ILVT) with other arrhythmias is very rare.

Interruption of the Atrioventricular Bundle with Congenital Atrioventricular Block [PDF]

Circulation, 1971
Two cases of congenital heart block were studied in which comprehensive serial section study of the conduction systems showed disruption of the penetrating portion of the atrioventricular (A-V) bundle. In one case, the branching portion of the A-V bundle was present together with the bundle branches.

Cardiogenic shock mortality according to Aetiology in a Mediterranean cohort: Results from the Shock‐CAT study

ESC Heart Failure, Volume 12, Issue 2, Page 1336-1345, April 2025.
Abstract Aims Mortality in cardiogenic shock (CS) remains elevated, with the potential for CS causes to impact prognosis and risk stratification. The aim was to investigate in‐hospital prognosis and mortality in CS patients according to aetiology. We also assessed the prognostic accuracy of CardShock and IABP‐SHOCK II scores.

Amplatzer Septal Occluder-induced Transient Complete Atrioventricular Block

Journal of the Formosan Medical Association, 2007
Percutaneous transcatheter atrial septal defect (ASD) closure is a widely used technique that has replaced open-heart surgical closure in many centers. The most common implant is the Amplatzer septal occluder which seems to be a highly effective and safe

FDG PET/CT imaging and circulating biomarkers of inflammation in desmoplakin cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1485-1489, April 2025.
Abstract Aims Inflammation has been implicated in the pathogenesis of desmoplakin (DSP) cardiomyopathy, and retrospective studies have described abnormal myocardial fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) findings in symptomatic patients eventually diagnosed with DSP cardiomyopathy.
