Comparison of patients undergoing protected high risk percutaneous coronary intervention using either intravascular lithotripsy or rotational atherectomy.

ABSTRACT:

Background

Treating heavily calcified vessels is a challenging task in patients with an impaired left ventricular ejection fraction. Percutaneous mechanical circulatory support (pMCS) is increasingly used in patients in high-risk percutaneous coronary intervention (HRPCI).

Methods

In this retrospective registry, we investigated 25 patients undergoing a protected HRPCI receiving either intravascular lithotripsy (IVL + pMCS; n = 11) or rotational atherectomy (RA + pMCS; n = 14). The primary endpoint was defined as peri-interventional hemodynamic stability. The secondary endpoint was defined as major adverse cardiac events (MACE).

Results

Patients in the IVL + pMCS group had a significantly higher mean arterial pressure (MAP) at the end of the procedure (
