Multicenter Study Comparative Study
Separate grafts or en bloc anastomosis for arch vessels reimplantation to the aortic arch.
This study compares the results of the separated graft technique and the en bloc technique as a method of arch vessels reimplantation during surgery of the aortic arch and determines the predictive risk factors associated with hospital mortality and adverse neurologic outcome during aortic arch repair. ⋯ Antegrade selective cerebral perfusion was confirmed to be a safe method of cerebral protection allowing complex aortic arch operations to be performed with acceptable results in terms of hospital mortality and neurologic outcome. The separated graft technique had no adverse impact on hospital mortality and morbidity.

Multicenter Study Clinical Trial
Minimally invasive mitral valve repair using the da Vinci robotic system.
Minimally invasive mitral valve repair with a shortened hospital stay and quick return to an active lifestyle is the ultimate goal for robotically assisted surgery. We evaluated our da Vinci robotically assisted mitral valve repair experience toward achieving this goal. ⋯ Mitral valve repair can be successfully performed with the da Vinci robotic system. Long-term follow-up is needed to determine the durability of the repair compared with a standard sternotomy approach.

Multicenter Study
Multivariable prediction of in-hospital mortality associated with aortic and mitral valve surgery in Northern New England.
Predicting risk for aortic and mitral valve surgery is important both for informed consent of patients and objective review of surgical outcomes. Development of reliable prediction rules requires large data sets with appropriate risk factors that are available before surgery. ⋯ We present results and methods for use in day-to-day practice to calculate patient-specific in-hospital mortality after aortic and mitral valve surgery, by the logistic equation for each model or a simple scoring system with a look-up table for mortality rate.
