Abstract:
The retrograde approach is a novel technique of percutaneous coronary intervention for chronic total occlusion. This technique has improved the success rate of guidewire passage through the occlusion. In the retrograde approach, a microcatheter and balloon are delivered through a retrograde channel. However, it is difficult for a stent to pass through collateral arteries. We report a case of coronary artery stenosis in a markedly tortuous right coronary artery for which a drug-eluting stent was delivered retrogradely via the atrial circumflex branch.
