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

Long-term outcomes of His bundle pacing in patients with heart failure with left bundle branch block

Heart, 2018
Objectives His bundle pacing (HBP) can potentially correct left bundle branch block (LBBB). We aimed to assess the efficacy of HBP to correct LBBB and long-term clinical outcomes with HBP in patients with heart failure (HF).

A retrospective audit of young adults who received permanent pacemakers at a teaching hospital in the Western Cape, South Africa

Frontiers in Cardiovascular Medicine, 2023
IntroductionWhile most pacemaker implantations occur in older individuals, younger patients also receive pacemakers. In these, degenerative conduction system disease is less likely to be the cause of atrioventricular block (AVB), with other diseases ...

Impact of Net Atrioventricular Compliance on Mitral Valve Area Assessment—A Perspective Considering Three-Dimensional Mitral Valve Area by Transesophageal Echocardiography

Diagnostics
Background: Net atrioventricular compliance (Cn) can affect the accuracy of mitral valve area (MVA) assessment. We assessed how different methods of MVA assessment are affected by Cn, and if patients with abnormal Cn may be identified by clinical and/or ...
