  2. Background Percutaneous treatment of left main (LM) trifurcation disease is a challenging procedure for most interventional cardiologists. Moreover, data on long-term outcomes after stent implantation for LM trifurcation disease are lacking. We thus conducted a retrospective cohort study focusing on our 5-year experience on stenting for LM trifurcation disease.

  3. Methods • A total of 27 patients underwent percutaneous coronary intervention with stent implantation for LM trifurcation disease from 11/10/2002 to 02/10/2006 were included. • Decision to perform PCI instead of surgery was taken on the basis of comorbidity and high risk score, unsuitable anatomy for surgery (size and quality of coronary vessels and/or conduits for grafting) and/or patient refusal of CABG. • LM trifurcation disease was defined as involvement of LM and at least one side branch or at least one side branch without LM involvement. 12 patients presented with (44%) true trifurcations, ie with all main and side branches significantly diseased.

  4. Baselinevariables Male 62% Mean Age 66.1 Diabetes 14% Hypertension 92% Hyperlipidemia 81% Smoke 25% Previous IMA 37% Previous CABG 7% Prior PCI 22% EF 53.4±8.25 Euroscore 5.97±3.57 Procedure Elective 66% Urgent 44% Clinical presentation AMI 44% Unstable angina 22% Stable angina 34%

  5. Index procedure and angiographic variables • Double antiaggregation 27/100% • IIb/IIIa 3/10% • Total stents/per patient 52/1.8 • DES 96%-BMS 29% of patients respectively Stenting techniques • V stenting 6/21% • T stenting 10/35% • One stent strategy 11/39% Angiographic variables • LM lesion 26/92% • RVD 3.68±0.37mm • Lesion length 14.8±6.15mm • Lesion class B2-60%/C-40% • LAD lesion 60% • LCX lesion 46% • RI lesion 50%

  6. Angiographic and procedural caracteristics

  7. Results • Pre TIMI 1 Post TIMI 3 (angiographic success 100%). • Clinical success 100%. • 1 in hospital death (3%). • Clinical follow-up completed on 27 pts (100%). • Angiographic follow-up completed on 22 pts (81%). • Overall MACE 33%

  8. Events at long term follow up

  9. Conclusions • Recurrence of angina appeared as a major predictor of poor outcome, as among 6 cases (22%) with recurrent symptoms, 2 died during follow-up and 2 underwent surgical bypass. • Percutaneous treatment of LM trifurcation disease is feasible and associated with favorable mid-term results, and should be considered given its low invasiveness in patients at high surgical risk or multiple comorbidities.
