Temporary mechanical circulatory support for Takotsubo cardiomyopathy secondary to primary mediastinal B-cell lymphoma.

BACKGROUND

Left heart mechanical circulatory support (MCS) through the left chest via the pulmonary vein and descending thoracic aorta is a good option for patients with an inaccessible anterior mediastinum and/or poor peripheral access.

MATERIALS AND

METHODS

We report the case of a 19-year-old small female with a newly discovered bulky primary mediastinal diffuse large B-cell lymphoma (PMBL) who developed refractory inverted Takotsubo cardiomyopathy (TC) with cardiogenic shock.

RESULTS

Temporary MCS was implemented in order to stabilize the patient and proceed with a chemotherapy treatment. Given the patient's oncologic "frozen" mediastinum and the presence of poor peripheral arterial access, the left heart temporary MCS was successfully implanted through a left mini-thoracotomy via the left inferior pulmonary vein and descending thoracic aorta.

CONCLUSIONS

This is the first report of temporary MCS to treat inverted TC and diffuse PMBL.
