["Catecholamine refractory" cardiogenic shock? "Bridging-to-recovery" by implantation of a percutaneous cardiac assist device].

HISTORY AND ADMISSION FINDINGS: A 27-year-old man presented with acute dyspnea and a previous respiratory tract infection with progressive dyspnoea and chest pain over 2 weeks. Clinical findings revealed severe cardiac failure with development of cardiogenic shock and need for adrenergic drug therapy for circulatory support.

INVESTIGATIONS: The electrocardiogram showed a sinus tachycardia with unspecific T-wave-inversions, the echocardiogram revealed a dilated left ventricle and severely reduced systolic LV-function. An acute coronary syndrome could be excluded by coronary angiogram.

TREATMENT AND COURSE: A myocardial biopsy was taken to exclude giant cell myocarditis. The immediate initiation of a mechanical circulatory support by an Extracorporal Membrane Oxygenator (ECMO) facilitated rapid hemodynamic stabilization and recovery of organ function.

CONCLUSIONS

A drug-only circulatory support very often does not enable stabilization of a patient in progressive cardiogenic shock and cannot prevent multiorgan dysfunction. Therefore implantation of an assist device facilitates a "bridging-to-recovery" or a "bridging-to transplant" concept in critically ill patients presenting with cardiogenic shock. The bridging also allows for reviewing etiology and evaluation of further treatment options. In case of recovery continuous care in a specialized Heart Failure Clinic can help to maintain the clinical status and offer frequent reevaluation of cardiac status and therapeutic concepts.
