Background: Between 40 and 60% of individuals following cardiac surgery report having postoperative right ventricular
dysfunction (RVD), which is a manifestation of decreased septal function (paradoxical septal motion).
Aim and objectives: To investigate the association between RVD and the outcome of cardiac surgery for mitral valve
intervention including morbidity and mortality up to 3 months after surgery.
Patients and Methods: A total of 47 patients were included in the prospective observational comparative evaluation,
which was split into two groups, group 1 [high risk group tricuspid annular plane systolic excursion (TAPSE) less than
1.6] and group 2 (low risk group TAPSE more than 1.6). The study took place from August 2019 to August 2021 at the
National Heart Institute (NHI) and the Cardiothoracic Surgery Department of Ain Shams University.
Results: There were nonsignificant differences demonstrated between the groups in terms of age, gender, body mass
index (BMI), mitral pathology, the duration of mechanical ventilation, ICU length of stay, the incidence of postoperative
bleeding, the volume of postoperative bleeding, the composite endpoint of complications, the type of complication, or the
lengths of ICU stay.
The high-risk group's TAPSE scores were found to be considerably lower at the 3-month evaluation (P<0.001).
Only two variables, preoperative TAPSE and cross-clamp time, were found to be statistically significant in predicting the
risk of all-cause death, according to the findings of the multivariate regression analysis.
Conclusion: RV dysfunction was detected by a thorough preoperative echocardiographic evaluation. Reducing surgical
adverse events and mortality may be possible with the identification of preoperative RV dysfunction.
