Abstract

Cryoballoon ablation for atrial fibrillation (cryoAF) is relatively simple, cost-effective and easy procedure. However, general anesthesia during this procedure may have negative impact on patients' mortality and morbidity, as well as procedure costs. We sought to assess the feasibility and safety of conscious sedation during cryoAF. Patients with paroxysmal or persistent, drug-refractory AF who underwent a first procedure of cryoAF were included in our single-center, retrospective study. The loading dose of midazolam was 2 mg and loading fentanyl dose was 25 µg intravenously. Additional doses of midazolam and fentanyl were administered, if necessary. Midazolam and fentanyl were administered to maintain amnesia and analgesia, and patients' responsiveness in Ramsay Sedation Score was assessed every 10 minutes with sedation kept at the Ramsey Sedation Scale not exceeding Ramsey 3 Grade. A total of 71 patients with mean age 59.5±11.1 years were enrolled (48 males, 68%). The TEE and the TEE-guided transseptal puncture was feasible in all patients. The mean duration of cryoAF procedure was 136.3±36.0 minutes. The overall mean midazolam and fentanyl used doses were: 5.1±3.1 mg (55.7±35.1 µg/kg) and 98.9±51.1 µg (1.13±0.60 µg/kg).

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
