Key result
Prolonged ventilation occurred in 30.67% of patients after open mitral valve surgery and was significantly associated with longer durations of cardiopulmonary bypass, ischemic time, and aorta clamp time.
Why the study?

What are the prognostic factors influencing prolonged ventilation after open mitral valve surgery?
Prolonged ventilation after open mitral valve surgery is significantly associated with procedural factors like ischemic time, aorta clamp time, and cardiopulmonary bypass duration, rather than baseline patient characteristics.
May heighten awareness of ventilation risk with extended bypass times in mitral surgery; hypothesis-generating and requires prospective confirmation.
Objective: To determine prognostic factors influencing prolonged ventilation after surgery in our hospital. Method: Seventy-five patients fulfilled inclusion criteria were included in this retrospective cross-sectional study. Prognostic factors analyzed were age, chronic pulmonary disease, heart failure (NYHA class function), left ventricular (LV) dysfunction (based on ejection fraction), recent myocardial infarction, pulmonary hypertension (PH), duration of cardiopulmonary bypass (CPB), ischemic time and aorta clamp time, which were analyzed in relation to prolonged ventilation after open mitral valve surgery. Results: Subjects were 75 patients aged between 19 and 62 years old (mean 39.76, SD 11.44) whom underwent open mitral valve repair or replacement surgery. Twenty-three patients (30.67%) had prolonged ventilation (≥24 hours) after surgery. Bivariate analysis showed there were no significant correlation between age, heart failure, PH and LV dysfunction. There are different with statistically significance between groups (p<0.05). Conclusions: In this study, almost one-third of patients had prolonged ventilation after surgery. Factors influencing this morbidity were the duration of ischemic time, aorta clamp time and CPB. Age, heart failure, LV dysfunction and PH were not statistically related to the prolonged ventilation event.

Supomo Supomo (2019) conducted a cross-sectional in Valvular heart disease requiring open mitral valve surgery (n=75). Intraoperative factors (CPB duration, ischemic time, aorta clamp time) was evaluated on Prolonged ventilation (≥24 hours) postoperatively (p=<0.05). Prolonged ventilation occurred in 30.67% of patients after open mitral valve surgery and was significantly associated with longer durations of cardiopulmonary bypass, ischemic time, and aorta clamp time.
