This study aimed to assess changes in right heart echocardiographic parameters and cardiac remodeling six months after laparoscopic sleeve gastrectomy (LSG).<b> </b></span><br> <span style="line-height:14pt"><b><i><span style="color:blue">Methods: </span></i></b>In this cross-sectional study, patients who underwent LSG between 2022 and 2024 were evaluated before surgery and at six-month follow-up. Demographic data, clinical variables, and comprehensive echocardiographic indices of cardiac function were recorded and compared.<i> </i></span><br> <span style="line-height:14pt"><b><i><span style="color:blue">Results: </span></i></b>Twenty-two patients (mean age 38.09&plusmn;9.47 years) were included. Significant postoperative improvements were observed in left ventricular ejection fraction (55.84&plusmn;6.49% to 62.86 &plusmn; 4.41%, p<0.001), right ventricular peak systolic myocardial velocity (12.22&plusmn;2.59 to 14.24&plusmn;2.38 cm/s, p<0.001), tricuspid annular plane systolic excursion (22.95&plusmn;3.03 to 24.18&plusmn;2.82 mm, p=0.04), E wave velocity (7.35&plusmn;2.01 to 9.54&plusmn;1.98 cm/s, p<0.001), and left ventricular global longitudinal strain (15.42&plusmn;3.86 to 18.24&plusmn;2.93, p<0.001). Significant reductions were noted in right ventricular diameter, left ventricular end-diastolic and end-systolic volumes, and pulmonary artery pressure (all p<0.01). The prevalence of diastolic dysfunction decreased markedly from 63.6% preoperatively to 13.6% postoperatively (p<0.001).<b><i> </i></b></span><br> <span style="line-height:14pt"><b><i><span style="color:blue">Conclusion: </span></i></b>Laparoscopic sleeve gastrectomy is associated with significant improvement in cardiac remodeling and both left and right ventricular function, with notable enhancement of right heart echocardiographic parameters.<b><i> </i></b></span></span></span><br> &nbsp;</p> Sleeve gastrectomy - echocardiography - cardiac function 121 127 http://caspjim.com/browse.php?a_code=A-10-1311-2&slc_lang=en&sid=1 Kağan Gökçe kgngkc@hotmail.com 100319475328460055807 100319475328460055807 No Department of General Surgery, Okan University, Istanbul, Turkey Hidayet Demir hidayet.demir.hd@gmail.com 100319475328460055808 100319475328460055808 No Cardiovascular Surgery Research Center, Okan University, Istanbul, Turkey Mehmet Altuğ Tunçer altug.tuncer@okan.edu.tr 100319475328460055809 100319475328460055809 No Cardiovascular Surgery Research Center, Okan University, Istanbul, Turkey Mehrdad Sheikhvatan med.msv@gmail.com 100319475328460055810 100319475328460055810 Yes Cardiovascular Surgery Research Center, Okan University, Istanbul, Turkey Hanie Abbasi hanie73abbasi@gmail.com 100319475328460055811 0009-0009-5711-8724 No Faculty of Medicine, Tehran University of Medical Sciences, Tehran, Iran
