[Effects of intra-aortic balloon pumping on mitral flow dynamics after aortocoronary bypass surgery].

abstract：BACKGROUND:There is an ongoing debate regarding optimal management of patients with paradoxical low gradient severe aortic stenosis (PLG-SAS). We hypothesized that the presence of symptoms is closely associated with future adverse outcome. We aimed to determine the relation between symptoms and outcome in patients with...
