Abstract

The purpose of this study was to assess computational analysis of 64-electrode basket catheter (BC) recordings of atrial fibrillation (AF) and atrial flutter using novel software, CARTOFINDER (CF). Repetitive patterns have been recorded during AF and reported to be an important mechanism of AF. CF was used to identify rotational repetitive activation patterns (RAPs) in the right (RA) and left atrium (LA). To assess for presence of RAPs, multiple 1-min BC maps of the RA and LA were obtained before and after radiofrequency ablation (RFA) around the pulmonary veins in 14 patients undergoing AF ablation. Validation of the CF algorithm was based on analysis of BC recordings of the cavotricuspid isthmus flutter. There were 2.9 rotational RAPs per patient (1.3 RA; 1.6 LA). No RAPs were noted in 2 patients. RFA was delivered on top of (n = 10), within 5 mm (n = 5), or distant (n = 10) from any RAP. Reproducibility of the BC to identify the same RAP was 82%. Post-pulmonary vein (PV) isolation, there was a 45% reduction in RAP versus pre-RFA. CF was validated by 4 electrophysiologists blindly reviewing 32 RA CF maps. Electrophysiologists correctly categorized presence/absence of RAP in 122 of 128 maps (95%). CF is novel software incorpor...Continue Reading

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.

Atrial Filbrillation

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