Abstract:
Objective To evaluate the safety of intracoronary Doppler flow measurement using Doppler FloWire Methods and Results A total of 906 patients were examined with intracoronary Doppler using a 0 014″ or a 0 018″ Doppler FloWire For coronary flow reserve measurement, intracoronary injection of adenosine or papaverine was used Of the patients studied, 77 were cardiac transplant recipients, 829 were nontransplant patients, of whom 617 patients underwent diagnostic coronary procedures and 212 had coronary interventions In 27 (2 98%) of 906 patients adverse cardiac events were observed Fifteen (1 66%) of 906 patients developed severe transient bradycardia (asystole or Ⅱ? to Ⅲ? atrioventricular block) after intracoronary administration of adenosine Of which, 14 occurred in RCA and 1 in LAD Nine (0 99%) of 906 patients experienced coronary spasm during the passage of the Doppler wire (5 in RCA, 4 in LAD) Two (0 22%) of 906 patients developed ventricular fibrillation during the procedure Hypotension with bradycardia and ventricular extrasystole each occurred in one (0 11%) of 906 patients The incidence of complication was significantly higher in transplant recipients than in nontransplant patients underwent either diagnostic or interventional procedures (12 99% vs 2 43% vs 0 94%, P
