BACKGROUND: Type C coronary lesions represent a complex angiographic scenario, although it is a rather common one in the daily clinical practice of percutaneous coronary intervention (PCI). Our objective was to report the national clinical practice outcomes of PCIs performed in patients with type C lesions. METHODS: Retrospective study, with information obtained from the electronic database of the National Center of Cardiovascular Interventions (Central Nacional de Intervenções Cardiovasculares - CENIC) of Sociedade Brasileira de Hemodinâmica e Cardiologia Intervencionista (SBHCI) which gathers information on PCI procedures in a dedicated database, entered by volunteer physicians members of different Brazilian institutions. RESULTS: Between January 2010 and December 2011 1,693 patients with type C lesions were registered in CENIC. Most patients were male (68%), with mean age of 63 ± 26.3 years, 40.9% were diabetic and 45.4% had acute coronary syndromes. Procedure success was achieved in 95.6% of the cases, mortality was 2.1%, acute myocardial infarction was observed in 5% and target-lesion revascularization in 0.5% of the patients during hospitalization. CONCLUSIONS: PCIs in type C lesions had high success and low complication rates in a selected population group of the CENIC registry. The former morphological classification of the lesions, still adopted in the registry, does not properly stratify the outcomes of PCI currently. Updating the data collection form and measures to improve the quality control of the registry are urgently needed.
