Intra-operative right ventricle function assessment in patients with
tumor thrombus in inferior vena cava by transesophageal
echocardiography:a retrospective cohort study
Objectives: To summarize intraoperative right ventricle function
assessments in patients with tumor thrombus in inferior vena cava
by transesophageal echocardiography. Design: Retrospective analysis.
Settings: University of Peking University People‘s Hospital
Participants: Patients who had experienced inferior vena cava tumor
resection from Jun 2014 to Oct 2021. Interventions: Analysis of
demographic data, intraoperative parameters including TEE
(transesophageal echocardiography) assessments on right ventricle (RV)
function, outcome data . Variables were compared between groups
according to the tumor invasion of right atrium (RA) or not.
Measurements and Main Results: Variables associated with intraoperative
outcomes were assessed. Fifteen patients were included in this analysis.
The invasion of RA was in 11 patients (73.3%). The intraoperative
parameters of right ventricle and vasoactive-inotropic score (VIS) were
analyzed. There weren’t significant differences between the VIS of Group
A and Group B(7.18±4.60 vs 7.50±6.76,p=0.918).The fractional area change
(FAC) and tricuspid annular plane systolic excursion (TAPSE) increased
significantly postoperatively. The right ventricle end-diastolic area
index (RVEDAI, ml/m2) of the cases invading the RA were larger than
those without the invasion of the right ventricle postoperatively. The
postoperative in-hospital days (POD) also lasted longer in RA involved
cases. Conclusions: Right ventricle systolic function improved in
patients with tumor thrombus in inferior vena cava (IVC)
postoperatively. Patients with tumor invasion in the RA would need
longer time to recover. In those patients, the strategy would be managed
when IVC obstruction was relieved for prophylaxis of acute RV failure.
