Key result
Minimally invasive surgery with VAVD is linked to ~50% lower hemolysis vs. traditional surgery.
Why the study?
The hemodynamic effects and risks of vacuum-assisted venous drainage (VAVD) in open heart surgery compared to traditional venous drainage were not well defined.
Does vacuum-assisted venous drainage (VAVD) provide adequate hemodynamics and safety compared to traditional venous drainage in patients undergoing open heart surgery?
Cohort (n=40)
Does vacuum-assisted venous drainage (VAVD) provide adequate hemodynamics and safety compared to traditional venous drainage in patients undergoing open heart surgery?
Vacuum-assisted venous drainage at -40 mmHg provides adequate cardiopulmonary bypass perfusion hemodynamics and can be used safely in robotic or minimally invasive open heart surgery.
Answers are grounded in this paper and cite their sources.
VAVD at -40 mmHg yielded comparable hemodynamics and outcomes in this small retrospective series; leaves open prospective confirmation of safety in minimally invasive cardiac surgery.

Solak et al. (2023) conducted a cohort in Open heart surgery (n=40). Robotic or minimally invasive open heart surgery with vacuum-assisted venous drainage (VAVD) vs. Traditional open heart surgery with traditional venous drainage was evaluated on Hemolysis. Robotic or minimally invasive open heart surgery with vacuum-assisted venous drainage provided adequate hemodynamics compared to traditional surgery, with hemolysis in 10% vs 20% of cases.
