Abstract

Reduction of radiation exposure during cardiac arrhythmia ablation procedures is desirable. We sought to evaluate the utility of a new image integration module (CARTOUNIVU(TM) ) in reducing fluoroscopy times and dosages during left atrial arrhythmia (LAA) and ventricular tachycardia (VT) ablation procedures. Consecutive patients undergoing LAA (n = 28)/VT (n = 13) ablation using the CARTOUNIVU(TM) module were included. Total fluoroscopy time, radiation dose (total dose area product [tDAP], effective dose [ED]), and procedure duration were evaluated. A retrospective cohort of patients who underwent LAA (n = 16)/VT(n = 8) ablation without the new image integration module served as a control group. The use of the new image integration module significantly reduced mean fluoroscopy time (5.2 minutes [IQR 1.9;6.8] in the LAA ablation UNIVU group vs. 28.2 minutes [IQR 15.3;37.8] in the control group, P<0.001; 9.8 minutes [IQR 4.5;13.1] vs. 25.5 minutes [IQR 14.1;30.9] for VT ablation, P = 0.013), tDAP (2,088 cGy*cm(2) [IQR 664;2911] vs. 5,893 cGy*cm(2) [IQR 3088;8483], P< 0.001 for LAA ablation; 3,917 cGy*cm(2) [IQR 948;4217] vs. 12,377 cGy*cm(2) (IQR 3385;23157) for VT ablation patients, P = 0.025) and ED (4.1 mSv [IQR 1;5.8] vs. 11....Continue Reading

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.
