What conventional preoperative parameters are associated with new-onset atrial fibrillation after TAVR?
Conventional preoperative markers, including older age, enlarged cardiac chambers, reduced LVEF, and elevated NT-proBNP, can help identify patients at high risk for new-onset atrial fibrillation after TAVR.
This study compared conventional preoperative parameters between transcatheter aortic valve replacement (TAVR) patients with and without post-procedural new-onset atrial fibrillation (NOAF) to identify simple risk markers. A total of 211 patients undergoing TAVR were enrolled. Post-procedural NOAF occurred in 19 patients (9.0%). Preoperative clinical baseline data, electrocardiographic parameters, conventional echocardiographic indices, laboratory findings, and perioperative variables were compared between the NOAF and No-NOAF groups. Compared with the No-NOAF group, patients with post-TAVR NOAF were significantly older (P = 0.002) and had a higher heart rate (P = 0.002). Echocardiographically, the NOAF group exhibited larger cardiac dimensions, including right ventricular diameter (P 0.05). Older age, higher heart rate, enlarged cardiac chambers (including right heart and left atrium), reduced left ventricular systolic function, elevated NT-proBNP, renal dysfunction, higher uric acid, lower total cholesterol, and increased monocyte percentage are associated with post-TAVR NOAF. These easily accessible conventional markers may facilitate early identification of high-risk patients in routine clinical practice, offering a practical alternative to advanced imaging techniques.
Tang et al. (Mon,) conducted a observational in Severe aortic stenosis (n=211). Preoperative clinical, echocardiographic, and laboratory risk markers vs. Patients without these risk markers was evaluated on New-onset atrial fibrillation (NOAF) after TAVR. Post-TAVR new-onset atrial fibrillation occurred in 9.0% of patients and was associated with older age, higher heart rate, enlarged cardiac chambers, elevated NT-proBNP, and renal dysfunction.
