No correlation was found between right ventricular performance parameters and the need for vasopressors post-cardiopulmonary bypass. There was also no association between initial right ventricular longitudinal strain and difficulty in weaning off bypass or increased demand for pressors. Changes in tricuspid annular plane systolic excursion across all cases warrant further investigation with a larger cohort.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Right ventricular longitudinal strain is a valuable tool for assessing right ventricular function post-mitral valve repair, offering insights into immediate postoperative outcomes and long-term right ventricular remodeling.
