Abstract: Aortic stenosis (AS), a progressive valvular disease that results in increasing left ventricular (LV) afterload, leads to ventricular dysfunction and heart failure if left untreated. Transcatheter aortic valve replacement (TAVR) has emerged as a minimally invasive and effective alternative to surgical replacement, especially in elderly or high-risk patients. Objectives: The present study aims to assess the influence of the tricuspid annular plane systolic excursion (TAPSE)/pulmonary systolic arterial pressure (PASP) ratio on clinical outcomes in patients with aortic stenosis undergoing TAVR and offer valuable insights into patient selection and tailored management strategies for individuals undergoing TAVR. Methods: A retrospective analysis was conducted on 100 patients with AS who underwent TAVR, included in two distinct groups based on their median TAPSE/PASP ratio. Results: Patients were divided according to their median TAPSE/PASP ratio into two groups. Those with lower TAPSE/PASP ratios had a higher incidence of post-procedural atrial fibrillation (AF) (48% vs. 28%, p = 0.0404), lower left-ventricular ejection fraction (LVEF) (41.06% vs. 49.50%, p < 0.0001), a more pronounced inflammatory and hematologic response, and longer hospitalization. Receiver-operating characteristic (ROC) analysis demonstrated modest but significant discrimination rather than high sensitivity or specificity for postprocedural arrhythmias, particularly atrial fibrillation. Conclusions: TAPSE/PASP should be regarded as a clinically useful risk-stratification marker in patients with AS undergoing TAVR, enabling the identification of high-risk patients and optimizing peri-procedural management.
