Read our disclaimer for details.
We performed a prophylactic peroperative linear 1-minute cryolesion connecting the tricuspid annulus and right atriotomy to prevent IART on 15 consecutive adult patients undergoing surgery for congenital heart disease. Conduction time between electrodes placed on both sides of the cryolesion was measured on the second postoperative day. Coronary angiography and electrophysiology study using an electroanatomic mapping system to assess conduction across the line were performed three month after the operation on 13 patients.
