[Surgical treatment of incessant atrial tachycardia: description of a case].
A 50 year old woman with no evidence of structural heart disease was referred for ectopic incessant repetitive atrial tachycardia uncontrolled by medical therapy. Intracavitary and transesophageal simultaneous recordings revealed the earliest atrial electrical activity to be located in the left atrium. Intraoperative electrophysiologic mapping demonstrated that the site of earliest atrial activation was in a small diverticulum of the left atrial appendage. Excision of the appendage and isolation of left atrium was carried out with restoration of sinus rhythm. The patient was arrhythmia-free till 24 months later. Surgical treatment appears to be an effective therapeutic option for drug-resistant ectopic atrial tachycardia.
