Classification, Electrophysiological Features and Therapy of Atrioventricular Nodal Reentrant Tachycardia.

Arrhythmia & Electrophysiology Review, 2016
Atrioventricular nodal reentrant tachycardia (AVNRT) should be classified as typical or atypical. The term 'fast-slow AVNRT' is rather misleading. Retrograde atrial activation during tachycardia should not be relied upon as a diagnostic criterion.

Perventricular Device Closure of Native Congenital Muscular Ventricular Septal Defects in Small Infants   $\hspace{0.17em}$ ≤ 5 kg: Single‐Center Study of the Risk Factors for Failure of the Intervention and Non‐Optimal Outcome

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background and Aims Perventricular device closure of muscular VSD in small infants is a less invasive option than surgical closure under cardiopulmonary bypass and offers better outcomes than palliative pulmonary artery banding. However, the specific risk factors that could affect procedural success and optimal outcomes have not been ...

The Role of Electrophysiologic Study in Device Selection for Leadless Atrial Pacing [PDF]

Texas Heart Institute Journal
The AVEIR DR (Abbott Medical) was the first dual-chamber leadless pacing system approved by the US Food and Drug Administration. Many patients with sinus node dysfunction have physiologically normal atrioventricular conduction, so an atrial-only pacing ...

Physiology of Atrioventricular Transmission [PDF]

Circulation, 1961
This paper describes records of the transmembrane action potential of fibers from different parts of the specialized conducting system and electrograms recorded directly from these fibers in situ. On the basis of these records it is possible to describe certain physiologic mechanisms for conduction delay, block, and supernormal conduction.

Percutaneous Ultrasound‐Guided Closure of Perimembranous Ventricular Septal Defects in Children Using Bioabsorbable Occluders—Feasibility and 1‐Year Follow‐Up

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background To reduce complications associated with metal occluders, bioabsorbable occluders have been implanted for perimembranous ventricular septal defects (VSDs) via transthoracic approach. This study investigates the feasibility of echocardiography‐guided percutaneous closure of perimembranous VSDs in children using bioabsorbable occluders,

Epidemiology, Pathophysiology, and Management of Native Atrioventricular Valve Regurgitation in Heart Failure Patients

Frontiers in Cardiovascular Medicine, 2021
Atrioventricular regurgitation is frequent in the setting of heart failure. It is due to atrial and ventricular remodelling, as well as rhythmic disturbances and loss of synchrony.

Arrhythmia induction using isoproterenol or epinephrine during electrophysiology study for supraventricular tachycardia [PDF]

, 2018
Background Electrophysiology study (EPS) is an important part of the diagnosis and workup for supraventricular tachycardia (SVT). Provocative medications are used to induce arrhythmias, when they are not inducible at baseline. The most common medication

Connexins and the atrioventricular node

Heart Rhythm, 2013
The structure and functioning of the atrioventricular (AV) node has remained mysterious owing to its high degree of complexity. In this review article, we integrate advances in knowledge regarding connexin expression in the AV node. Complex patterning of 4 different connexin isoforms with single channel conductances ranging from ultralow to high ...

Balloon‐Expandable Versus Self‐Expanding Valves in Bicuspid Aortic Stenosis: Insights From the SWEDEHEART Registry

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter aortic valve replacement (TAVR) is increasingly used in patients with bicuspid aortic valve (BAV) stenosis, but there is limited comparative data on balloon‐expandable (BEV) versus self‐expanding valves (SEV) in this population. Aim To compare clinical and hemodynamic outcomes between BEVs and SEVs in patients with BAV
