ALCOHOL SEPTAL ABLATION FOR HYPERTROPHIC OBSTRUCTIVE CARDIOMYOPATHY: THE AUCK- LAND EXPERIENCE

patients in whom FFR ≥0.80 and did not undergo intervention. Method: 61 consecutive lesions in 51 patients with FFR ≥0.80 were retrospectively identified at Waikato hospital between January 2006 and January 2008. Outcomes assessed at 1–3 year included recurrent angina, revascularization and death. Results: The mean patient age was 64.4 years (72% males) with a mean follow-up period of 23 months. The group included 18% diabetics, 67% dyslipidemics, 71% hypertensives and 37% smokers. Lesions assessed were in the Left Main 13%, LAD 57%, Circumflex 15% and RCA 15%. Under conditions of maximal hyperaemia the mean FFR for the cohort was 0.87 (0.80–0.98). Symptoms were minimal during follow-up of 23 months; 78% patients had no further angina and 94% did not require any further intervention. None of the patients within this group died. Conclusion: An FFR of greater than 0.80 predicts an excellent longer termoutcome at 2 yearswith conservative management and is a valuable aid to prevent unnecessary interventions in equivocal lesions. doi:10.1016/j.hlc.2009.04.063
