The Tricuspid Annular Plane Systolic Excursion (TAPSE)\/Pulmonary Arterial Systolic Pressure (PASP) ratio is an echocardiographic parameter reflecting right ventricular (RV) function and pulmonary circulation. This study aimed to evaluate the predictive value of the TAPSE\/PASP ratio for hypotension after general anesthesia induction. Methods: This prospective observational study included 79 patients with no known cardiac disease who were scheduled for elective surgery and classified as having a physical status of I\u2013III according to the American Society of Anesthesiologists (ASA). TAPSE, PASP, and RV function were assessed using transthoracic echocardiography (TTE) within 5\u201330 min before surgery, and their hemodynamic changes after general anesthesia induction were recorded. Results: Data analysis revealed a significant association between the TAPSE\/PASP ratio and the occurrence of hypotension following the induction of general anesthesia (p &lt; 0.001). In addition, a cut-off value of \u22641.98 was determined for predicting hypotension, which demonstrated a sensitivity of 72.5% and a specificity of 64.1% (AUC = 0.733, 95% CI: 0.621\u20130.826, p &lt; 0.001). Conclusions: The TAPSE\/PASP ratio is a potential predictor of hypotension following the induction of general anesthesia. Further studies are required to validate its predictive accuracy and clinical utility in perioperative hemodynamic management.<\/jats:p>","DOI":"10.3390\/diagnostics15111404","type":"journal-article","created":{"date-parts":[[2025,6,2]],"date-time":"2025-06-02T03:19:38Z","timestamp":1748834378000},"page":"1404","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Preoperative TAPSE\/PASP Ratio as a Non-Invasive Predictor of Hypotension After General Anesthesia Induction"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3774-7418","authenticated-orcid":false,"given":"Ferdi","family":"G\u00fcla\u015ft\u0131","sequence":"first","affiliation":[{"name":"Department of Anesthesiology and Reanimation, Faculty of Medicine, Adnan Menderes University, Ayd\u0131n 09010, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7640-1295","authenticated-orcid":false,"given":"Sevil","family":"G\u00fcla\u015ft\u0131","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Faculty of Medicine, Adnan Menderes University, Ayd\u0131n 09010, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-2771-2186","authenticated-orcid":false,"given":"B\u00fc\u015fra Ceyhan","family":"Can","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology and Reanimation, Faculty of Medicine, Adnan Menderes University, Ayd\u0131n 09010, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8112-4934","authenticated-orcid":false,"given":"Hakan","family":"\u00d6zt\u00fcrk","sequence":"additional","affiliation":[{"name":"Department of Biostatistics, Faculty of Medicine, Adnan Menderes University, Ayd\u0131n 09010, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1467-8619","authenticated-orcid":false,"given":"Sinem","family":"Sar\u0131","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology and Reanimation, Faculty of Medicine, Adnan Menderes University, Ayd\u0131n 09010, T\u00fcrkiye"},{"name":"Outcomes Research Consortium, Houston, TX 77030, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,5,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1217","DOI":"10.1097\/ALN.0b013e3181c14930","article-title":"Intraoperative hypotension and 1-year mortality after noncardiac surgery","volume":"111","author":"Bijker","year":"2009","journal-title":"Anesthesiology"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1654","DOI":"10.1213\/ANE.0000000000005250","article-title":"Intraoperative Hypotension Is Associated with Adverse Clinical Outcomes After Noncardiac Surgery","volume":"132","author":"Gregory","year":"2021","journal-title":"Anesth.
