Key result
Transcatheter aortic valve implantation generally demonstrates a lower incidence of new-onset atrial fibrillation compared to surgical aortic valve replacement, with transfemoral access showing the lowest risk.
Why the study?
New-onset atrial fibrillation post-TAVI predicts poor outcomes with unclear pathophysiology, broadly variable reported incidence, and highly variable management strategies.
TAVI generally has a lower incidence of NOAF compared to SAVR, but NOAF remains a serious complication with variable management strategies requiring further investigation.
May support TAVI preference in AF-prone patients; leaves open standardized management and prospective confirmation.
Transcatheter Aortic Valve Implantation (TAVI) is an established treatment option for patients with aortic stenosis who are considered highrisk for surgical valve replacement. New-onset atrial fibrillation (NOAF) is a serious adverse event post TAVI that is predictive of poor outcomes and whose pathophysiology remains unclear. The incidence of NOAF post-TAVI has a reportedly broad range depending on the study but has been correlated to procedure approach, choice of valve, and the use of general anesthesia. While surgical aortic valve replacement (SAVR) has traditionally been the preferred treatment for aortic stenosis, recent studies have demonstrated the benefits of expanding TAVI into a larger patient population. Additionally, the management of NOAF post-TAVI remains highly variable. This review paper aims to summarize the incidence of NOAF and to outline management strategies.

Supna Saxena (2020) conducted a review in Aortic Stenosis and New-Onset Atrial Fibrillation. Transcatheter Aortic Valve Implantation (TAVI) vs. Surgical Aortic Valve Replacement (SAVR) was evaluated on Incidence of New-Onset Atrial Fibrillation (NOAF). Transcatheter aortic valve implantation generally demonstrates a lower incidence of new-onset atrial fibrillation compared to surgical aortic valve replacement, with transfemoral access showing the lowest risk.
