Analysis of the same valve position cardiac valve reoperation / 中华胸心血管外科杂志

ABSTRACT

Objective:To summarize the experience of surgical treatment of prosthetic valve dysfunction and evaluate the safety of operation.Methods:The clinical data of 142 patients admitted by the same cardiovascular surgeon from January 2015 to December 2019 at the first medical center of Chinese People's Liberation Army General Hospital. The clinical data were retrospectively analyzed, including 60 males (42.25%) and 82 females (57.75%), with an average age of 59.4 years old. Inclusion criteria patients received redo-valvuloplasty or valve replacement after valvuloplasty or replacement, excluding mitral balloon dilatation and tricuspid valvuloplasty without implantation of annuloplasty ring.Results:The reasons of redo heart valve surgery in the same valve position including bioprosthetic valve failure, mechanical prosthetic valve dysfunction, valve dysfunction after valvuloplasty, prosthetic valve infectious endocarditis, perivalvular leakage. There was 2 death in 142 cases, and the operative mortality rate was 1.41%. The reasons of the perioperative period death include cerebral hemorrhage, coagulation dfsfunction; perioperative complications include low cardiac output syndrome (LCOS), hypoxic-ischemic encephalopathy, respiratory failure, tracheal re-intubation, re-thoratomy for hemaostsis.Conclusion:There are many reasons for reoperation of prosthetic valve dysfunction, and the reoperation surgery is a difficult procedure. However, choosing the suitable surgical option, strengthening the perioperative management of such patients can effectively reduce the incidence of postoperative mortality and complications, minimally invasive surgery can reduce the mortality and complications.
