Key result
Pneumonectomy linked to ~24% higher RVSP vs. lobectomy postoperatively.
Why the study?
The effects of major lung resection on right heart function have not been well established.
Cohort (n=86)
Absolute Event Rate: 31% vs 25%
p-value: p=<0.05
No takes yet. Share an insight, caveat, or question.
Pneumonectomy may mildly raise postoperative pulmonary pressures without RV dysfunction; leaves open whether serial echocardiography improves risk stratification after lung resection.
Amar et al. (1996) conducted a cohort in Major lung resection (n=86). Pneumonectomy vs. Lobectomy was evaluated on Right ventricular systolic pressure on postoperative days 2 through 6 (p=<0.05). Pneumonectomy was associated with higher right ventricular systolic pressure compared to lobectomy on postoperative days 2 through 6 (31 vs 25 mm Hg; p<0.05).
