Insights
Cardiac tamponade during atrial fibrillation ablation is rare. Most cases resolve with pericardiocentesis, but significant bleeding or drainage over 1000 ml may necessitate surgery.
Area of Science:
- Cardiology
- Cardiac Surgery
- Electrophysiology
Background:
- Cardiac tamponade (CT) management during atrial fibrillation (AF) ablation lacks clear guidelines.
- Decisions between conservative therapy and surgery are often empirical.
Purpose of the Study:
- To summarize the management of CT during AF ablation.
- To develop a management pathway for CT post-AF ablation.
Main Methods:
- Retrospective analysis of patients who developed CT post-AF ablation from 2013-2019.
- Classification of CT patients into bleeding severity groups.
- Statistical analysis to identify predictors for surgical intervention.
Main Results:
- 32 out of 4887 patients (0.65%) developed CT and underwent pericardiocentesis.
- 14 patients required surgical intervention due to bleeding.
- Drainage volume > 970 ml in the first hour predicted surgical repair (p=0.04).
- Perforation sites were commonly near pulmonary vein antrum.
Conclusions:
- Surgical intervention for CT during AF ablation is infrequent.
- Pericardiocentesis with drainage > 1000 ml or accelerated bleeding warrants consideration for emergency surgery.
Introduction:
The critical decision between conservative therapy and surgical intervention to manage cardiac tamponade (CT) during atrial fibrillation (AF) ablation remains empirical. The aim of the study was to summarize the experience in management of CT during AF ablation to derive a proper management pathway.
Methods:
All patients with CT who underwent catheter ablation for AF in our center from 2013 to 2019 were included.
Results:
In total of 4887 patients, 32 (0.65%) patients occurred CT and received pericardiocentesis and immediate reversal of anticoagulation. All the CT patients were classified into three groups: rapid and uncontrollable bleeding who needed urgent surgical intervention (4/32), continuous bleeding (14/32), once pericardiocentesis, and no further bleeding (14/32). In the continuous bleeding group, the drainage volume in the first hour after pericardiocentesis was statistically related to surgical repair (p = 0.04) with a cutoff point of 970 ml (AUC 0.84, sensitivity 71.4%, specificity 100%, p = 0.04). During surgical repair, most of perforation sites were detected at superior anterior wall of left atrium close to right or left superior pulmonary vein antrum. No patient died of CT in our cohort.
Conclusions:
Only a small proportion of patients with CT required surgical intervention during AF ablation. When pericardiocentesis was performed, if a drainage volume was more than 1000 ml in the first hour or bleeding was accelerated after an hour of observation, emergency surgical repair should be recommended.
