Udrożnienie techniką retrograde przewlekle zamkniętej prawej tętnicy wieńcowej

Chronic total occlusion (CTO) is defined as an occlusion of a coronary vessels (TIMI 0 flow) lasting longer than 3 months. Successful recanalisation of CTO improves left ventricular function and survival. Retrograde technique can be used in patients, who have well-developed collaterals, when the antegrade approach is ineffective or difficult to perform. A 68-year-old male was referred for coronary angiography because of exercise angina chest pain. Coronary angiogram showed a CTO of RCA with collaterals from LAD. Following the unsuccessful traditional antegrade approach in 2004, we attempted a retrograde approach. The PCI procedure was performed successfully and without complications.
