Outcome analysis for prediction of intraaortic balloon pump support failure and long-term survival in high-risk patients undergoing mitral valve surgery.

Abstract：

:The outcome predictors of intra-aortic balloon pump (IABP) in patients who undergo mitral valve surgery remain unknown. This study aimed to retrospectively review valvular surgery in patients who received an IABP to identify the predictors of failure of IABP support and anticipate the necessary therapy. This retrospective observational study recruited a total of 157 consecutive patients who underwent open-heart mitral valve surgery with IABP implantation intraoperatively or postoperatively. Univariate and multivariate logistic regression analyses were performed to identify the risk factors attributed to 30-day mortality. Follow-up data of survivors were collected to investigate the effect of IABP support to evaluate long-term outcomes. The overall 30-day mortality was 35.7% (56 patients). The following factors that contributed to 30-day mortality included sepsis (P < .001, OR: 5.627, 95%CI: 2.422-11.683); IABP implantation postoperatively rather than intraoperatively (P = .001, OR: 6.395, 95%CI: 2.085-19.511); right heart failure (P = .042, OR: 3.419, 95%CI: 1.225-12.257); and lack of subvalvular apparatus preservation (P = .033, OR: 3.710, 95%CI: 1.094-13.167). Furthermore, follow-up data of these patients showed an estimation of 5-year and 10-year survival rates of 58.9% and 35.7%, respectively. Patients with intraoperative IABP demonstrated better long-term survival outcomes when compared to those with postoperative IABP (χ2 = 4.291, P = .038). In summary, this study distinguished the preoperative predictors of 30-day mortality of IABP-support in mitral valve surgery patients. These results indicated that early intervention with IABP should be taken into consideration in case of hemodynamic instability in critically ill patients undergoing mitral valve surgery.
