Ablation of idiopathic ventricular tachycardia by bipolar radiofrequency current application between the left aortic sinus and the left ventricle
Key result
Bipolar radiofrequency application between the aortic sinus of Valsalva and the left ventricle permanently suppressed idiopathic ventricular outflow tract tachycardia in a single patient.
Why the study?
Does bipolar radiofrequency current application between the left aortic sinus and the left ventricle suppress tachycardia in patients with idiopathic ventricular outflow tract tachycardia resistant to conventional ablation?

Implication
Bipolar ablation succeeded in one resistant case; hypothesis-generating and should not yet change practice for outflow tract tachycardia.

Structured PICO
Does bipolar radiofrequency current application between the left aortic sinus and the left ventricle suppress tachycardia in patients with idiopathic ventricular outflow tract tachycardia resistant to conventional ablation?
P
Population
1 patient with idiopathic ventricular outflow tract tachycardia resistant to conventional unipolar radiofrequency application.
I
Intervention
Bipolar radiofrequency current application between the distal electrode of an aortic catheter (left aortic sinus of Valsalva) and the distal electrode of a second catheter placed in the left ventricular subaortic area
O
Outcome
Permanent suppression of tachycardia
Bipolar radiofrequency application between the aortic sinus of Valsalva and the left ventricle may serve as an effective alternative approach for idiopathic ventricular outflow tract tachycardia resistant to conventional unipolar ablation.
Cite This Study
José Luís Merino (2000) conducted a case report in Idiopathic ventricular outflow tract tachycardia (n=1). Bipolar radiofrequency current application between the left aortic sinus and the left ventricle vs. Conventional left ventricular and aortic root unipolar radiofrequency application was evaluated on Suppression of tachycardia. Bipolar radiofrequency application between the aortic sinus of Valsalva and the left ventricle permanently suppressed idiopathic ventricular outflow tract tachycardia in a single patient.
