Clinical experience of copulsation with PAD via left ventricular apex

Copulsation was performed with a pulsatile assist device (PAD) via the left ventricular apex in two patients who could not be weaned from cardiopulmonary bypass and IABP support after open-heart surgery. In one case an essential improvement of cardiac status was achieved while in the second case the mechanical support was unsuccessful. Clinical data suggest that this technique may have potential in promoting the recovery of ischaemic myocardium but problems related to the type of cannula used and the site of intraventricular location need further investigation.
