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.

Complete atrioventricular septal defect repair in Australia: Results over 25 years.

Journal of Thoracic and Cardiovascular Surgery, 2020
OBJECTIVES To evaluate whether the long-term outcomes of modified-single-patch (MSP) repair of complete atrioventricular septal defect are equivalent to double-patch (DP) repair with respect to survival and risk of reoperation for left atrioventricular ...

Characterization of pathological remodeling in the chronic atrioventricular block cynomolgus monkey heart

Frontiers in Pharmacology, 2023
We studied time course of pathological remodeling occurring in the cynomolgus monkey hearts against persistent atrioventricular block condition (n = 10).

Atrioventricular Valve Failure in Fontan Palliation.

Journal of the American College of Cardiology, 2019
BACKGROUND Atrioventricular valve failure (moderate or greater regurgitation, or valve operation) is a risk factor for adverse outcomes in patients undergoing Fontan palliation.

Long-term outcome after early repair of complete atrioventricular septal defect in young infants.

Journal of Thoracic and Cardiovascular Surgery, 2020
OBJECTIVE The long-term outcome after repair of complete atrioventricular septal defect in young infants is still not fully understood. The objective of this study was to evaluate data after repair for complete atrioventricular septal defect over a 25 ...

Prenatal ultrasound diagnostics of atrioventricular communication in combination with the tetralogy of Fallot in a fetus with Down's syndrome phenotype

Репродуктивная эндокринология, 2022
This article presents a description of our own case of ultrasound prenatal diagnostics of complex combined heart disease (complete atrioventricular communication in combination with tetralogy of Fallot) at 19–20 weeks of gestation with ultrasound markers

T-box transcription factor 3 governs a transcriptional program for the function of the mouse atrioventricular conduction system

Proceedings of the National Academy of Sciences of the United States of America, 2020
Significance Genome-wide association studies have identified common noncoding variants associated with ECG parameters in the TBX3 locus, suggesting that a modest change in TBX3/Tbx3 expression level affects heart function. We characterized the morphology,

Nephronectin regulates atrioventricular canal differentiation via Bmp4-Has2 signaling in zebrafish [PDF]

, 2011
The extracellular matrix is crucial for organogenesis. It is a complex and dynamic component that regulates cell behavior by modulating the activity, bioavailability and presentation of growth factors to cell surface receptors.

Risk Factors Associated With Atrioventricular Block

JAMA Network Open, 2019
Key Points Question Are there readily modifiable risk factors associated with the risk of atrioventricular block? Findings In this population-based cohort study of 6146 community-dwelling individuals, elevated blood pressure and blood glucose levels were

Rate-dependency of action potential duration and refractoriness in isolated myocytes from the rabbit AV node and atrium [PDF]

, 2000
During atrial fibrillation, ventricular rate is determined by atrioventricular nodal (AVN) conduction, which in part is dependent upon the refractoriness of single AVN cells.
