This single-center prospective observational study aimed to assess the correlation of net atrioventricular compliance (Cn) with pulmonary artery pressure in 26 adult patients with severe mitral stenosis (MS) undergoing surgical mitral valve replacement (MVR). Cn was estimated by doppler echocardiography, and pulmonary artery pressures measured by pulmonary artery catheter. Early outcomes including duration of intensive care unit (ICU) stay, mechanical ventilation duration, and vasoactive inotropic scores (VIS) were recorded. Cn showed moderate to strong negative correlation with systolic, diastolic, and mean pulmonary artery pressures at all time points. Receiver operating characteristic (ROC) curve analysis determined a cut-off of 2.31 to predict postoperative pulmonary artery systolic pressure. Cn with a cut-off value of 2.3 ml\/mmHg serves as an indicator of persistent pulmonary hypertension following MVR surgery.<\/jats:p>","DOI":"10.1177\/10892532261425015","type":"journal-article","created":{"date-parts":[[2026,2,10]],"date-time":"2026-02-10T13:59:18Z","timestamp":1770731958000},"page":"183-190","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Net Atrioventricular Compliance: A Determinant of Pulmonary Artery Pressure in Patients Undergoing Mitral Valve Replacement for Severe Mitral Stenosis"],"prefix":"10.1177","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-1390-2175","authenticated-orcid":false,"given":"Nischitha","family":"Gowda","sequence":"first","affiliation":[{"name":"Postgraduate Institute of Medical Education and Research"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1397-339X","authenticated-orcid":false,"given":"Sunder","family":"Lal Negi","sequence":"additional","affiliation":[{"name":"Postgraduate Institute of Medical Education and Research"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Goverdhan Dutt","family":"Puri","sequence":"additional","affiliation":[{"name":"Postgraduate Institute of Medical Education and Research"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rupesh","family":"Kumar","sequence":"additional","affiliation":[{"name":"Postgraduate Institute of Medical Education and Research"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Prashant","family":"Panda","sequence":"additional","affiliation":[{"name":"Postgraduate Institute of Medical Education and Research"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,2,10]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9149(96)00539-5"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.12.1.69"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjcard.2007.04.060"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.3329\/cardio.v8i2.26806"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.echo.2007.08.024"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/0735-1097(92)90284-T"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1253\/circj.71.1721"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCIMAGING.112.000328"},{"key":"e_1_3_3_10_2","doi-asserted-by":"publisher","DOI":"10.1136\/heartjnl-2016-310955"},{"key":"e_1_3_3_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jsha.2017.01.001"},{"key":"e_1_3_3_12_2","doi-asserted-by":"publisher","DOI":"10.3329\/cardio.v13i2.52972"},{"key":"e_1_3_3_13_2","doi-asserted-by":"publisher","DOI":"10.1111\/echo.12256"},{"key":"e_1_3_3_14_2","first-page":"27","article-title":"Determinants of left atrial pressure in rheumatic mitral stenosis: role of left atrial compliance and \u201cAtrial Stiffness\u201d","volume":"56","author":"Kapoor A","year":"2004","unstructured":"Kapoor A, Kumar S, Shukla A, et al.
