Hi, TARV is an option for people with a high risk in open-heart surgery. There's an evaluation to go of couse, including heart function(class I and class II), anatomical conditions of the aortic root. Also TARV is recommended to people over 70, because no one knows for how long exacty the new valve can function well. This surgery only started in 2002. The TARV sugery needs one cardiologist and two cardiac sugeons to work together, so ideally you choose a multidiscipline hospital. The best hospital for heart surgery ranks Cleveland, mayo, Smidt Heart Institute at Cedars-Sinai , New York-Presbyterian, Massachusetts General, University of Pennsylvania-Penn Presbyterian, Northwestern Memorial.
