Abstract
IntroductionCardiac tamponade is a rare but life-threatening complication during atrial fibrillation (AF) catheter ablation. Contact force (CF)–sensing catheters improve ablation effectiveness. However, the impact of the application of CF-sensing catheters on the occurrence of cardiac tamponade remains unclear. The aim of this study is to evaluate the “real-world” impact of CF-sensing catheters on cardiac tamponade during AF ablation in an experienced medical center.Methods and resultsThis was a retrospective study of consecutive de novo AF ablation procedures at Beijing Anzhen Hospital between 2013 and 2016. The ablation procedure was divided into a CF group and a non-CF group. Logistic regression analysis was used to evaluate the association between the use of CF-sensing catheters and the risk of cardiac tamponade. A total of 5313 patients with AF were involved in this study. The incidence of cardiac tamponade in the CF group was significantly higher than that in the non-CF group (1.07% vs. 0.44%, P = 0.009). Of the cardiac tamponade cases in the non-CF group, 45.45% were delayed compared with 10% in the CF group (P = 0.011). Multivariate logistic regression analysis showed that CF-sensing catheters increased the risk of cardiac tamponade (OR = 2.34, 95% CI = 1.17–4.26, P = 0.015). Stratified analysis revealed patients with a smaller left atrium dimension, lower ejection fraction, longer procedure duration, or longer ablation duration had a greater risk of cardiac tamponade during ablation with CF-sensing catheters.ConclusionsCF-sensing catheters increase the risk of cardiac tamponade during AF ablation.
Highlights
Cardiac tamponade is a rare but life-threatening complication during atrial fibrillation (AF) catheter ablation
Tamponade occurred in one patient during the electroanatomic reconstruction of the left atrium using the non-Contact force (CF)-sensing catheter before ablation
We propose the following interpretations: (1) CF is a critical factor for cardiac tamponade, the occurrence of cardiac tamponade is the result of an extensive interaction among CF, ablation power, time, temperature, and impedance; all the above parameters should be carefully monitored during the ablation procedure [22]
Summary
Cardiac tamponade is a rare but life-threatening complication during atrial fibrillation (AF) catheter ablation. Contact force (CF)–sensing catheters improve ablation effectiveness. The aim of this study is to evaluate the Breal-world^ impact of CF-sensing catheters on cardiac tamponade during AF ablation in an experienced medical center. Cardiac tamponade is a rare but life-threatening complication during catheter ablation for atrial fibrillation (AF) [1, 2]; the incidence of cardiac tamponade is 1.2–1.31% in worldwide. Contact force (CF)–sensing catheters have been widely adopted in AF ablation. They provide the operator with real-time monitoring of contact pressure between the ablation catheter tip and cardiac tissue.
