The total procedural success rate was 89.7%. The retrograde group had significantly higher incidences of periprocedural myocardial infarction and coronary perforation (7.3% vs. 3.7%, p=0.01; 7.9% vs. 4.4%, p=0.04, respectively). Median follow-up duration was 7.7 (interquartile range 5.6-8.7) years. Seven-year relative risk comparing the retrograde and antegrade groups was neutral in all-cause death (adjusted HR [aHR] 1.06, 95% CI: 0.75-1.49; p=0.745), cardiac death (aHR 0.85, 95% CI: 0.47-1.55; p=0.598), coronary artery bypass grafting (aHR 1.62, 95% CI: 0.74-3.54; p=0.229), and non-target vessel revascularisation (aHR 0.96, 95% CI: 0.78-1.17; p=0.663).</p><p class="text-1er-paragraph"/><p class="text-1er-paragraph"><span class="abstracts-titres">Conclusions:</span> Retrograde CTO PCI did not lead to worse long-term outcomes despite increased risk in periprocedural myocardial infarction and coronary perforation.</p> AU - Tanaka Hiroyuki AU - Ohya Masanobu AU - Kubo Shunsuke AU - Miura Katsuya AU - Otsuru Suguru AU - Habara Seiji AU - Tada Takeshi AU - Fuku Yasushi AU - Goto Tsuyoshi AU - Kadota Kazushige VL - 14 IS - 11 Y1 - 07/12/2018 Y1 - 2018 DOI - 10.4244/EIJ-D-18-00534 SP - e1183 EP - e1191 KW - chronic coronary total occlusion KW - death KW - stable angina PB - Europa Digital & Publishing SE - CORONARY INTERVENTIONS UR - https://eurointervention.pcronline.com/article/impact-of-retrograde-approach-on-long-term-clinical-outcomes-of-patients-undergoing-coronary-chronic-total-occlusion-interventions SN - 1774-024X ER -
