Abstract

OBJECTIVE: The aim is to evaluate the feasibility of using mechanical circulatory support, specifically the Impella device, in spontaneous coronary artery dissection (SCAD) patients with cardiogenic shock.

BACKGROUND: The therapeutic options for managing SCAD complicated by cardiogenic shock are limited. Risky revascularization procedures are often necessary.

METHODS: This was a multicenter case series in the United States. Approximately 20 cases of Impella implantation in patients with SCAD are known. The implanting physician for each of these cases was contacted and de-identified records were requested. The records were analyzed for Impella indications, outcomes, and complications.

RESULTS: Records from four cases were received. All patients survived to hospital discharge and no major complications were observed. In two cases, cardiogenic shock developed in the absence of ongoing ischemia, suggesting a Takotsubo-like cardiomyopathy. In these cases, the Impella provided hemodynamic support until the patient's cardiac function recovered.

CONCLUSION: Although a small case series, given the scarcity of SCAD cases complicated by cardiogenic shock and the limited therapies available to treat these patients, these data are of clinical value in highlighting the feasibility of Impella use in SCAD. The Impella can be valuable for procedural support and in cardiogenic shock, especially in cases without evidence of ongoing ischemia.
