Permanent pervenous atrial pacing from the coronary vein is a reliable method of atrial pacing that avoids thoracotomy.
Answers are grounded in this paper and cite their sources.
May support coronary vein pacing to avoid thoracotomy; leaves open need for prospective validation of durability and safety.
Permanent pervenous atrial pacing from the coronary vein has been attempted in 14 patients. Several types of arrhythmias including symptomatic bradycardia, "bradytachy" syndrome, and refractory ventricular tachyarrhythmia-fibrillation have been successfully treated with pervenous atrial pacing in 10 patients for 1 to 30 mo. Longterm atrial pacing was unsuccessful in four patients; in two of these four this was due to high atrial pacing thresholds. To date there has been no evidence of pacemaker perforation or pacemaker-induced coronary vein thrombosis. It is concluded that permanent pervenous atrial pacing from the coronary vein is a reliable method of atrial pacing without resorting to thoracotomy.
