Why the study?
Does pneumonectomy affect right heart pressures and right ventricular dilatation?
Does pneumonectomy affect right heart pressures and right ventricular dilatation?
Pneumonectomy, particularly right-sided, leads to elevated pulmonary pressures and right ventricular dilatation at 6 months, driven by reduced FVC, older age, and hypoxia.
May warrant serial RV imaging post-pneumonectomy; leaves open whether targeted interventions improve outcomes.
Pneumonectomy is related with postoperative elevation of PASP and RV dilatation, especially right pneumonectomy. Significant percent FVC reduction, increased age and low pO2 values are the main responsible factors for elevation of the 6-month postoperative PASP values.
