Hemorheologic and hemodynamic problems to investigate protective intracoronary perfusion through the dilation catheter (DC) during percutaneous transluminal coronary angioplasty (PCTA) 1

Abstract

Under specific hemorheologic and hemostasiologic conditions (P_cath1200 mmHg, hematocrit value lesser than 30%, adequate heparinisation) it is possible to archieve a sufficient flow rate through the narrow lumen (0.5 mmØ) of the dilatation catheter (DC) during PTCA to exert a myocardial protective effect of the myocardium distal to the balloon. This prevents hemodynamic deterioration and should permit longer duration of balloon inflation.
