Anatomical Ablation of the Atrioventricular Node [PDF]

Arrhythmia & Electrophysiology Review
Background: Atrioventricular (AV) conduction ablation has been achieved by targeting the area of penetration of the conduction axis as defined by recording a His bundle potential. Ablation of the His bundle may reduce the possibility of a robust junctional escape rhythm. It was hypothesised that specific AV nodal ablation is feasible and safe. Methods:

The effects of leaflet material properties on the simulated function of regurgitant mitral valves [PDF]

, 2023
Advances in three-dimensional imaging provide the ability to construct and analyze finite element (FE) models to evaluate the biomechanical behavior and function of atrioventricular valves. However, while obtaining patient-specific valve geometry is now possible, non-invasive measurement of patient-specific leaflet material properties remains nearly ...

Ultrastructure of the mesothelioma of the atrioventricular node [PDF]

Cancer, 1977
In order to determine the histogenesis of tumors of the atrioventricular node, so-called conduction tumors, two such tumors were serially blocked for electron microscopy. Ultrastructurally these tumors were composed of nests of cells arranged in small channels and tubules set in a connective tissue stroma. The cells lining the tubules were flattened or

Clinical evaluation of nebulized verapamil in out‐patients with pulmonary hypertension secondary to chronic obstructive pulmonary disease

The Clinical Respiratory Journal, Volume 16, Issue 12, Page 802-811, December 2022., 2022
Single dose nebulized verapamil inhalation showed improvement in V/Q mismatch throught increase FVC. Nebulized verapamil inhalation improved gas exchanged and increased spO2. Nebulized verapamil inhalation for out‐patients with pulmonary hypertension secondary to chronic obstructive pulmonary disease improved spirometric parameter.

AV‐node isolation as an alternative to AV‐node ablation in patients undergoing pace & ablate strategy

Journal of Cardiovascular Electrophysiology, Volume 33, Issue 12, Page 2606-2613, December 2022., 2022
Abstract Introduction Atrioventricular (AV)‐node ablation (AVNA) is a common therapy option for rate control strategy of permanent atrial fibrillation (AF). We hypothesized that isolation of the AV nodal isolation (AVNI) is associated with a more frequent preservation of an adequate escape rhythm compared to AVNA.

Correlation between AV synchrony and device collected AM‐VP sequence counter in atrioventricular synchronous leadless pacemakers: A real‐world assessment

Journal of Cardiovascular Electrophysiology, Volume 34, Issue 1, Page 197-206, January 2023., 2023
Abstract Introduction Micra atrioventricular (AV) provides leadless atrioventricular synchronous pacing by sensing atrial contraction (A4 signal). Real‐world operation and reliability of AV synchrony (AVS) assessment using device data have not been described.

A comprehensive and biophysically detailed computational model of the whole human heart electromechanics [PDF]

, 2022
While ventricular electromechanics is extensively studied, four-chamber heart models have only been addressed recently; most of these works however neglect atrial contraction. Indeed, as atria are characterized by a complex physiology influenced by the ventricular function, developing computational models able to capture the physiological atrial ...

Multiple anterograde atrioventricular node pathways in patients with atrioventricular node reentrant tachycardia

Journal of the American College of Cardiology, 1996
This study sought to investigate electrophysiologic characteristics and possible anatomic sites of multiple anterograde slow atrioventricular (AV) node pathways and to compare these findings with those in dual anterograde AV node pathways.Although multiple anterograde AV node pathways have been demonstrated by the presence of multiple discontinuities ...

The right ventricle under pressure: Anatomy and imaging in sickness and health

Journal of Anatomy, Volume 242, Issue 1, Page 17-28, January 2023., 2023
The RV is essential to the homeostasis of normal physiology and disturbances in RV structure and function has a substantial effect on patient outcomes. This review sets out to describe the developmental and anatomical complexities of the right ventricle while exploring the modern techniques employed to image and understand its function from a clinical ...
