VENTRICULAR FUNCTION DURING CARDIAC SURGERY

描述：（改编自研究者摘要）在本修订版中 研究人员希望追求两个主要目标：扩大Q2-DE 儿童患者群体，并建立 电导导管法测定成人心室容积 患者 他们还希望在术中以及第2周和第6周进行研究 术后6个月， 心脏手术治疗各种瓣膜先天性和缺血性病变。 随着心室容积测量方法的发展， PI希望将这些数据与压力测量值结合联合收割机，以评估 手术期间和长达6个月的心肌力学和水肿 事后

DESCRIPTION: (Adapted from investigator's abstract) In this revised application the investigators wish to pursue two main goals: expand Q2-DE to the pediatric population of patients and establish the utility of the conductance catheter method for measurement of ventricular volumes in adult patients. They also wish to study intra-operatively and at 2 and 6 weeks and 6 months postoperatively both adult and pediatric patients that had open heart surgery for a variety of valvular congenital and ischemic lesions. With the development of reliable methods to measure ventricular volume, the PI wishes to combine these data with pressure measurements to assess myocardial mechanics and edema during operation and up to six months afterwards.
