We aimed to appraise current evidence and characterize contemporary use of tMCS in HRCS across selected U.S. Transplant Centers.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The authors have conducted a cross\u2010sectional survey for tMCS use for HRCS. This survey was conducted using the RedCap system evaluating the timing of support, device selection, and technical considerations. The response rate was 74%.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>For isolated coronary artery bypass grafting (CABG) patients with left ventricular ejection fraction (LVEF) 25%\u201335%, no\u2010tMCS and intra\u2010aortic balloon pump were the common approaches. In isolated CABG patients with LVEF less than 25%, more surgeons consider tMCS use including Impella 5.5. For CABG with mitral repair or replacement, more surgeons consider the use of tMCS. The annual volume of Impella 5.5 use for HRCS cases was \u2264\u200910 cases annually. For arterial access for Impella 5.5, the rate of trans\u2010aortic and trans\u2010axillary approach were equal. For HRCS, the simultaneous approach was more predominant, and most surgeons advance Impella to the left ventricle after the cross\u2010clamp is off. Most surgeons leave Impella 5.5 for 72\u2009h to 1\u2009week. For patients with severe aortic insufficiency, one\u2010fourth of surgeons have performed Impella 5.5 insertion.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Contemporary practice demonstrates increasing adoption of tMCS use in HRCS with a trend toward preemptive implementation of support.
