Comparison of CHADS ₂ , R ₂ CHADS ₂ , and CHA ₂ DS ₂ -VASc Scores for the Prediction of Rhythm Outcomes After Catheter Ablation of Atrial Fibrillation

Abstract

Background-Recurrences of atrial fibrillation (AF) occur in up to 30% within 1 year after catheter ablation. This study evaluated the value of CHADS 2 , R 2 CHADS 2 , and CHA 2 DS 2 -VASc scores for the prediction of rhythm outcomes after AF catheter ablation.

Impact of Catheter Ablation for Paroxysmal Atrial Fibrillation in Patients With Sick Sinus Syndrome – Important Role of Non-Pulmonary Vein Foci –

“…We used matched non-SSS controls to evaluate AF recurrence in SSS patients, because the characteristics of these patients, such as high age, hypertension, and cardiovascular disease, could be associated with AF recurrence. 13- 15 The AF recurrence rate was significantly higher in the SSS group than in the matched non-SSS controls, indicating that other factors may underlie the recurrence of AF in patients with SSS.…”

EHRA/HRS/APHRS/SOLAECE expert consensus on atrial cardiomyopathies: definition, characterization, and clinical implication

“…However, late recurrences are common and associated with more advanced atrial substrate associated with structural heart disease. [436][437][438][439][440][441][442][443][444][445][446] It is in this context that it is important to consider the various types of underlying atrial cardiomyopathy and how they may affect ablation outcomes. This is timely, as it has recently been observed that lone AF is a rapidly disappearing entity as we recognize conditions such as sleep apnoea, obesity, endurance exercise etc.…”

“…167,455 Numerous studies have evaluated ablation outcomes in ageing patients (variously defined as .65 through to .80). 444,445,[456][457][458][459][460][461][462] Observational studies have consistently reported high multiple procedure success rates at 12 months of up to 80% in older patients. Conflicting data exist regarding outcomes in comparative studies with one study demonstrating a reduced success rate in patients over 65 years while another study showed similar efficacy in patients over the age of 80 years to the younger cohort.…”

Repeat Catheter Ablation of Long-standing Persistent Atrial Fibrillation in Patients with a Total Atrial Fibrillation Duration of More Than 2 Years: Effects of the CHA₂DS₂-VASc Score and Estimated Glomerular Filtration Rate on the Outcomes

“…Recently, a series of studies have demonstrated the CHA2DS2-VASc score to be a significant predictor of adverse events in patients undergoing the catheter ablation (14). It also serves as a combined risk predictor of first cardiovascular hospitalization for patients with AF and a risk factor of recurrence after catheter ablation (3,15,16). Furthermore, Park et al proved that the electroanatomical remodeling of the left atrium (LA) was related to the CHA2DS2-VASc score in patients with non-valvular AF (17).…”
