Aortic intervention guided by contrast-enhanced transoesophageal ultrasound whist waiting for cardiac transplantation: a case report.

BACKGROUND

Aortic complications can happen during left ventricular assist devices (LVADs) insertion and its treatment remains challenging. Percutaneous aortic interventions can be an alternative to surgery in such high-risk cases.

CASE SUMMARY: We present a patient with idiopatic dilated cardiomyopathy and advanced heart failure requiring LVAD insertion as a bridge to transplant, who developed an aortic pseudoaneurysm below the anastomosis of the LVAD tube. He was successfully treated with percutaneous coiling under contrast-enhanced transoesophageal echocardiography (TOE) guidance, reaching destination therapy (heart transplantation) a year later.

DISCUSSION: Left ventricular assist devices provide haemodynamic support for patients with advanced heart failure waiting for heart transplantation. Although uncommon, aortic complications can happen as a result of LVAD insertion and be life-threatening. Percutaneous aortic interventions can be performed in such cases to promote thrombosis and remodelling of false lumen or aneurysmatic spaces, hence potentially reducing the risk of sudden death. Contrast-enhanced TOE can be easily and safely used to monitor the intervention in order to improve anatomic definition, guide positioning of wires and catheters and assess early results.
