Key result
Pulmonary resection significantly shortened right ventricular acceleration time from 144 msec preoperatively to 117 msec on postoperative day 1 (p<0.001), indicating increased right ventricular afterload.
Why the study?
Does pulmonary resection cause right ventricular dysfunction as assessed by pulsed Doppler echocardiogram in patients without prior heart disease?
Observational (n=26)
No
Does pulmonary resection cause right ventricular dysfunction as assessed by pulsed Doppler echocardiogram in patients without prior heart disease?
Pulmonary resection induces right ventricular diastolic dysfunction, which is detectable by pulsed Doppler echocardiography as early as postoperative day 1 and persists at 2 weeks.
May warrant RV monitoring after lung resection; leaves open effects on outcomes and requires prospective confirmation.

Ono et al. (1998) conducted an observational in Patients undergoing pulmonary resection (lobectomy or bilobectomy) (n=26). Pulmonary resection (lobectomy or bilobectomy) vs. Preoperative baseline was evaluated on Right ventricular acceleration time (AT) at postoperative day 1 (p=<0.001). Pulmonary resection significantly shortened right ventricular acceleration time from 144 msec preoperatively to 117 msec on postoperative day 1 (p<0.001), indicating increased right ventricular afterload.
