About this trial

This is an interventional treatment trial for Atrial Flutter

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  1. Clinical indication for corrective operation for congenital heart disease with the use of a right lateral atriotomy,
  2. Age >18 years,
  3. Ability to give an informed consent.

Exclusion Criteria:

  1. Acute operation
  2. Chronic atrial fibrillation
  3. Indication for MAZE procedure

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Prophylactic intervention

Arm Description

We performed a prophylactic peroperative linear lesions connecting the tricuspid annulus with a right atriotomy (surgical dissection plus cryoablation) and the atriotomy with the inferior caval vein (cryoablation alone). Conduction times between electrodes placed on both sides of the lesions are measured on the second postoperative day. Coronary angiography and electrophysiology study using an electroanatomic mapping system to assess conduction across the line and to try to induce atrial flutter are performed three month after the operation. There is only an intervention arm, no control arm

5. Study Description

Brief Summary
The investigators performed a prophylactic peroperative linear lesions connecting the tricuspid annulus with a right atriotomy and the atriotomy with the inferior caval vein to prevent atrial flutter on 15 consecutive adult patients undergoing surgery for congenital heart disease. Conduction time between electrodes placed on both sides of the lesions is measured on the second postoperative day. Coronary angiography and electrophysiology study using an electroanatomic mapping system to assess conduction across the line are performed three month after the operation.
