Experience of Balloon Aortic Valvuloplasty for Severe Aortic Stenosis in Patients Scheduled for Open Surgery for Chronic Limb-Threatening Ischemia.

To estimate the effectiveness of balloon aortic valvuloplasty (BAV) for severe aortic stenosis (SAS) in patients scheduled for open surgery for chronic limb-threatening ischemia. Clinical data of patients from 2012 to 2018 were retrieved and summarized. The early outcomes and survival after BAV and open bypass were retrospectively investigated. BAV was performed on seven dialysis patients. One patient died of mesenteric infarction 3 days after BAV; however, six patients were able to undergo open bypass at an average of 10 days (7-19 days) after BAV. One patient died of hemorrhagic shock before the wound healed; five patients underwent limb salvage. Four of these five patients could not undergo surgical aortic open valve replacement owing to advanced age or poor cardiac function and died within 2 years. Only one patient who underwent radical surgery after a bypass survived more than 4 years. BAV enabled open surgery and limb salvage in patients with SAS. Although BAV alone cannot ensure long-term survival, the procedure will continue to be important as a bridge technique to radical surgery, such as transcatheter aortic valve implantation and aortic valve repair, which are often avoided owing to infection.
