Abstract:
Objective:To explore the application value of virtual reality(VR) technology in the surgical diagnosis and treatment of congenital heart disease complicated with ventricular outflow tract stenosis.Methods:From November 2017 to October 2018, a total of 11 cases of congenital heart disease complicated with ventricular outflow tract stenosis were diagnosed and treated by VR technology assisted surgery in our center, including 9 cases of tetralogy of Fallot, 1 case of right ventricular double outlet stenosis and 1 case of right ventricular double outlet complicated with right ventricular outflow tract and pulmonary valve stenosis. The matching degree and value score of VR model by surgeons after operation. The data of these cases, including postoperative severe complications, maximum flow velocity and peak pressure difference and left ventricular ejection fraction(LVEF) 3 months after surgery, were retrospectively analyzed to evaluate the application value of VR technology and summarize the application experience of our center.Results:The operations were successful in all the 11 cases with no death in hospital. No serious complications related to the ventricular outflow tract occurred after the operation. The peak systolic velocity of the ventricular outflow tract in all the patients decreased to less than 2 m/s, and LVEF was in the normal range three months after the operation. In terms of VR model scores, the matching degree of all cases was 8/10 or above and 8 patients received a 3/3 of value score.Conclusion:For patients with congenital heart disease complicated with ventricular outflow tract stenosis, VR technology based on CT three-dimensional reconstruction can help surgeons more intuitively understand the spatial location information of each intra- and extra-cardiac structure and evaluate the feasibility of key surgical procedures, which is conducive to individual surgery and guarantees a good surgical outcome.
