ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the long-term outcomes of successful or failed revascularization in patients with chronic total occlusions (CTO).</p><p><b>METHODS</b>The clinical data of 1332 consecutive patients underwent percutaneous coronary intervention (PCI) for CTO between June 1993 and December 2006 in our hospital were analyzed. These patients were divided into two groups according to the procedural success (n = 1202) or failure (n = 130).</p><p><b>RESULTS</b>Overall success rate of procedure was 90.2% (1202/1332). The patients in CTO success group experienced a superior 10-year survival rate (76.9% vs. 64.6%, log rank P = 0.012) and a significantly higher no major adverse cardiovascular event (MACE) survival rate (41.8% vs. 27.6%, log rank P < 0.001) compared to the patients in CTO failure group. During the long-term follow-up, the proportion of patients who accepted coronary artery bypass grafting (CABG) was significantly lower in CTO success group than that in the CTO failure group (4.3% vs. 14.6%, P < 0.001).</p><p><b>CONCLUSION</b>Successful PCI procedure leads to increased long-term survival and MACE-free survival and the reduced need for CABG for patients with CTO lesions.</p>
