Case: We report a case of an infected iliac artery aneurysm complicated by an aortocaval fistula.

Outcome: A 74-year-old-man was admitted with fever, chills, general fatigue, and appetite loss. The patient was diagnosed with an infected iliac artery aneurysm, which was controlled with antibiotics preoperatively.

Mechanisms of the preventive effect of pilsicainide on atrial fibrillation originating from the pulmonary vein.

Background: It has been shown that pilsicainide terminates atrial fibrillation (AF) by pharmacologic pulmonary vein (PV) isolation. However, whether it can prevent AF induction originating from the PV by the same mechanism is still uncertain.

Methods And Results: Rapid pacing from the left superior PV (LSPV) and the right atrial free wall (RAF) was performed to induce AF during electrical stimulation of both cervical vagal nerves in 6 anesthetized dogs and during the infusion of acetylcholine (ACh) in 8 isolated atria.
