RESUMO
A 43-year-old young lady had closed mitral valvotomy (CMV) in 1994 and aortic valve replacement (AVR) in June 2007. Shortly thereafter, she presented with unstable angina in October 2007 with on-going pain and haemodynamic instability. Coronary angiogram showed tight left main bifurcation stenosis in a left dominant system. Having had open heart surgery (AVR) recently, and being on oral anticoagulation, with on-going ischaemia and unstable haemodynamics, percutaneous coronary intervention (PCI) was considered the most suitable option. She underwent successful PCI with two drug-eluting stents (T-stenting) to left main bifurcation through transradial approach and intra-aortic balloon support. Clinically she remained symptom free and coronary angiogram after 5 months and 15 months of follow-up showed patent stents. This case demonstrates the acute effectiveness of PCI for the treatment of critical left main disease following open heart surgery in patients who are not appropriate surgical candidates.
