OBJECTIVES Fulminant myocarditis with cardiogenic shock requires extracorporeal life support (ECLS) and has poor outcomes. To improve outcomes, we have converted patients with severely impaired cardiac and multiorgan function from peripheral to central ECLS. In this study, we reviewed these patients’ clinical outcomes and investigated associated factors. METHODS We retrospectively studied 70 consecutive patients with fulminant myocarditis under peripheral support from 2006 to 2020. Forty-eight patients underwent surgical conversion to central support, and the remaining patients continued peripheral support. The end point was survival and ventricular assist device-free survival. RESULTS More severe pulmonary congestion and multiorgan failure were present in patients with central than peripheral support. Weaning from ECLS was achieved in 95% and 62% of patients with peripheral and central support, respectively. Five-year survival was not significantly different between patients with central and peripheral support (71.2% vs 87.5%, respectively; P = 0.15). However, the ventricular assist device-free survival rate was significantly higher in patients with central than peripheral support (82.2% vs 52.0%, respectively; P = 0.017). A peak creatine kinase-MB level of >180 IU/l, rhythm disturbance and aortic valve closure were detrimental to functional recovery in patients with central support. CONCLUSIONS Conversion to central ECLS is feasible and safe in patients with fulminant myocarditis. Patients with severe myocardial injury as shown by a high creatine kinase-MB level, rhythm disturbance and aortic valve closure should be converted to a durable left ventricular assist device.

Acquired coarctation of the aorta (CoA) following total aortic arch replacement (TAR) is a rare complication inducing left ventricular (LV) dysfunction probably due to increased LV afterload and secondary hypertension caused by increased upper body and decreased renal blood flow. We describe a case of a 35-year-old male who developed atypical CoA with severe LV dysfunction with LV ejection fraction of 10%, but without secondary hypertension after TAR using conventional elephant trunk (ET) technique for acute aortic dissection. Computed tomography revealed near-occlusive CoA due to narrowed distal ET. Because the myocardial histological findings were mild, and he had no cardiac failure history, we determined that LV function might be reversible. He underwent thoracic endovascular aortic repair (TEVAR), resulting in restored LV function. However, as the descending aortic false lumen distally to the end of ET was rapidly dilated, probably due to increased cardiac output and lower body blood flow, he underwent descending aortic replacement 3 months after TEVAR. In conclusion, a narrowed distal ET may cause LV dysfunction early after TAR, even without secondary hypertension. TEVAR may be a useful therapeutic option for a narrowed distant ET but can induce distal aortic dilatation. < Learning objective: A 35-year-old male demonstrated that acquired coarctation of the aorta due to a narrowed distant elephant trunk led to left ventricular (LV) dysfunction with comparable severity of dilated cardiomyopathy even with normal blood pressure. Thoracic endovascular aortic repair is an effective treatment option to restore LV function by decreasing LV afterload. However, a narrowed distal ET relief with an increased cardiac output might cause distal aortic dilatation.>
