“…Chronic total occlusions (CTOs) of coronary arteries are complex lesions present in approximately 30% of patients undergoing coronary angiography (Grantham et al 2009). CTOs are defined, as lesions present for at least 3 months with grade 0 to 1 Thrombolysis in Myocardial Infraction (TIMI) flow on angiography.…”

“…The true incidence of CTO in the general population is not known due to a large proportion of asymptomatic or oligosymptomatic cases. In angiographic studies CTO is found in 20-40% of patients with established coronary artery disease [1][2][3][4]. For many years, CTO was a major indication for surgical myocardial revascularisation or continued medical therapy.…”

A b s t r a c tBackground and aim: Percutaneous coronary interventions (PCI) within chronically occluded coronary arteries remain challenging procedures with a lower success rate compared to classic PCI. However, over the last years we have witnessed many technological advances in the treatment of chronic total occlusion (CTO) including new wires, retrograde approach, subintimal tracking and re-entry technique, all underlying which the current success rate of up to 95% in dedicated centres. Subintimal space wire penetration is no longer a problem that would require terminating the procedure. It is now a desired part of hybrid CTO approach involving both antegrade and retrograde crossing and re-entry. The new device which facilitates controlled dissection and true lumen re-entry is the Boston Scientific Coronary CTO Crossing System consisting of a CrossBoss microcatheter and Stingray balloon and dedicated wire. Methods: On October 29th and 30 th , 2014, percutaneous coronary recanalisation using the CrossBoss/Stingray system was performed in 3 men aged 63-75, with symptoms of stable CCS class II/III angina, without prior myocardial infarction in the area of CTO artery supply and with preserved myocardial contractility. Each patient underwent at least one previous unsuccesful antegrade/retrograde CTO recanalisation procedure. The J-CTO score was 3-4. Results:The procedure was successful in all 3 patients: 2 right coronary arteries and 1 left anterior descending artery were opened. In all 3 cases, both the CrossBoss catheter and the Stingray re-entry system were used. Two to three drug eluting stents were implanted in each patient, with the total length of 62-106 mm and final TIMI 3 flow. The mean procedure time was 141 min (130-150 min), mean fluoroscopy time was 53 min (48-56 min), absorbed dose was 4772 mGy (4098-5633 mGy), dose area product was 565,208 cGy × cm 2 (535,109-590,266 cGy × cm 2 ), and the mean contrast volume was 343 mL (320-350 mL). No procedure-related complications were note except for an asymptomatic increase in high-sensitivity troponin T level up to 157 ng/mL (reference range 0-14 ng/mL) in 1 patient. Conclusions:The Boston Scientific Coronary CTO Crossing System is a useful device for percutaneous recanalisation of chronically occluded coronary arteries. It helps to achieve procedural success in more complex cases within relatively short crossing times and with a limited amount of the contrast agent and X-ray dose.
