To Bridge or Not to Bridge?

ObjectiveVentricular assist devices (VAD) are an important therapy that saves the lives of candidates a waiting heart transplantation (HTx). However, there are questions about posttransplantation effects of VADs.MethodsSeventy-four patients with end-stage heart failure who underwent HTx in our clinic between February 2007 and July 2011 were divided into two groups; a bridge cohort (n = 28) and a nonbridge group comprising 46 who underwent HTx without mechanical circulatory support. There mean ages were 39.89 ± 15.66 and 38.33 ± 16.23 years respectively. Significantly more patients in the bridge group, were man displayed anemia, were treated with anticoagulation therapy, and underwent a resternotomy. In the nonbridge group, more patients needed preoperative inotropic support.ResultsMultiple logistic regression analysis revealed preoperative renal failure (P = .007, odds ratio [OR] 27) and inotropic support (P = .006, OR: 10,222) as well as longer cardiopulmonary bypasses (≥130 minutes, P = .001, OR: 11,24) to be risk factors for in-hospital mortality, which was 15.2% in nonbridge and 10.7% in bridge subjects, P = .733). Major adverse events, such as renal failure, pulmonary failure, right ventricular failure, neurological event, and reoperation due to bleeding, shown similar incidences between the groups. The amount of blood transfusion was significantly higher in the bridge group (2.34 U versus 3.56 U, P = .037). The preoperative incidence of human leukocyte antigen sensitization (panel reactive antibody ≥ 10%) and grade 2R were rejection episodes in the early period were similar.ConclusionEarly posttransplant results were not adversely or beneficially influenced by the use of VADs. Similar to other types of cardiac surgery, a patients preoperative condition seemed to be the major factor affecting mortality.
