Atrial fibrillation
Conditions
Interventions
The following extra actions are required for linear DC-ablations:
1. Instead of a non-steerable sheath through the interatrial septum we will use
a steerable sheath. The steerable sheath is registere

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Adequate position of the linear DC-ablatie caheter. This is defined be visually good wallcontact by intracardiac ultrasound (ICE) and electrical signals from the electrodes on the linear ablation catheter Acute effect. This is defined as a successful ablation line with a complete and bidirectional electrical block. Adverse events. 1. Pericardial effusion 2. Cardiac tamponade 3. Thrombo-embolic complications 4. Illness or trauma due to catheter ablation 5. Temporary or permanent loss of bodily function 6. Any event that leads to early abortion of the procedure 7. Any event that leads to prolonged hospitalization 8. Any event that leads to a surgical intervention 9. Death Clinical one-year follow-up. 1. Documented atrial fibrillation or atrial tachycardia of >30 seconds duration, confirmed by a 12-channel ECG or Holter-ECG 2. Occurance of abovementioned adverse events during the outpatient time period. | — |
Secondary
| Measure | Time frame |
|---|---|
| We will register the duration of the total ablation procedure and the duration of the individual phases of the procedure: 1. The time necessary to position the linear catheter on any of the 2 target areas and the time of the ablations in both areas. 2. The necessity of using the steerable sheath for the correct positioning of the linear catheter will also be investigated in this pilot study. | — |
