Application of myocardial contrast-enhanced ultrasound in heart transplantation in patients with acute myocardial infarction：A case report

Background: MCE is a safe and effective myocardial perfusion assessment technique; it is used for the assessment of post MI viability. Case presentation: A 52-year-old male with cardiogenic shock caused by secondary acute myocardial infarction and successful coronary stent implantation with ECMO, IABP and ventilator assistance and with no significant recovery of postoperative cardiac function. The result of MCE was also reported. The allograft was successfully performed 8 days after ECMO-assisted support. The patient was successfully transferred to the general ward 8 days after surgery and successfully discharged on day 86 of admission. Conclusions: : ECMO provides effective mechanical assistance support for patients with end-stage heart failure, buys time for heart transplantation surgery, and was an effective cardiopulmonary support treatment. An evaluation of myocardial perfusion and survival quantity was an important reference for emergency heart transplantation.
