| Summary: | Abstract Introduction The indications for concominant tricuspid valve surgery in patients undergoing mitral valve surgery for rheumatic reasons are limited. The aim of our study was to investigate the effects of severe pulmonary hypertension and low TAPSE values on early-term mortality and morbidity in patients undergoing mitral valve replacement. Methods The data of all patients who underwent mitral valve replacement between January 2013 and August 2020 were examined retrospectively. Patients were divided into 2 groups according to pulmonary artery pressure (PAP ≥ 50 and PAP < 50). The group with PAP > 50 was then divided into 2 subgroups according to TAPSE (1.5 ≥ or < 1.5) values. The early-term mortality and morbidity rates of these groups were compared. Results Seventy-nine patients who underwent mitral valve replacement were included in the study. Fifty-four (68%) of them were female, and 25 (32%) were male. During the preoperative period, the TAPSE was 16.8 ± 3.0 mm, and the PAP was 52.1 ± 14.1 mmHg. There were 53 patients with PAP > 50 and 26 patients with PAP < 50. In the PAP > 50 group, the rates of tricuspid regurgitation (p < 0.001), blood transfusion (p < 0.001), intensive care unit stay (p < 0.001), need for CPAP (p = 0.043), reintubation (p = 0.048), acute renal failure (p = 0.028), and mortality (p = 0.026) were found to be significantly different. Conclusion In conclusion, we believe that in patients with mitral valve pathology, early referral for surgical intervention, before the pulmonary pressures significantly increase and right ventricular function deteriorates, can enhance survival outcomes. |
