Why the study?

Does lung resection surgery impair biventricular systolic and diastolic function in patients without preexisting cardiopulmonary disease?

Key Points

Right ventricular ejection fraction declined significantly post-surgery, highlighting impaired cardiac performance and increased RV workload.
Right ventricular systolic pressure increased from 20 ± 2.6 to 24.9 ± 5.0 mmHg, indicating increased strain on the heart after resection procedures.
This study utilizes ERNV scanning and echocardiography to assess biventricular function two months post-lobectomy and pneumonectomy.
These findings support the need for enhanced preoperative cardiac evaluation to mitigate postoperative complications related to significant lung resections.

Structured PICO

Does lung resection surgery impair biventricular systolic and diastolic function in patients without preexisting cardiopulmonary disease?

Population

20 patients (mean age 43.8 ± 8.3 years, 10 females, 10 male) undergoing lobectomy (n = 15) or pneumonectomy (n = 5) at a tertiary university hospital. Excluded: preexisting coronary disease, hypertension, or abnormal pulmonary function (e.g., predicted postoperative FEV1 or DLCO < 60%).

Intervention

Lung resection surgery (lobectomy or pneumonectomy)

Comparator

Preoperative baseline

Outcome

Changes in right and left ventricular ejection fraction (EF), peak filling rate (PFR), time to peak filling rate (TPFR) measured by ERNV, and Right Ventricular Systolic Pressure (RVSP) measured by echocardiography at two months postoperativelysurrogate

Lung resection surgery induces substantial biventricular systolic and diastolic dysfunction proportional to resection extent, detectable by ERNV scanning.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Warrants caution for biventricular dysfunction after lung resection without preexisting disease; leaves open long-term impact and should not yet change practice.
