Implication

Simplifies canine AV block models for research; leaves open translation to other species or clinical use.

Key Points

To evaluate a modified, simplified surgical technique for producing complete atrioventricular block in dogs using anatomical landmarks and formaldehyde injection.
Injected a 38% formaldehyde solution directly into the atrioventricular (AV) node region in dogs (N=20).
Used the coronary sinus as the primary anatomical landmark, avoiding entry into cardiac chambers and eliminating the need for specialized equipment.
Complete atrioventricular block was successfully achieved in 100% of subjects (20 of 20 dogs).
The procedure caused minimal to no hemorrhage at the injection site, with ventricular arrhythmias observed as the only complication in 10% of subjects (2 of 20 dogs).
