title: Complex intervention of an in-stent restenosis of ostial right coronary artery stent protruding into aortic sinus of Valsalva: a case report and brief review of the literature.
abstract: Aorto-ostial lesions are technically challenging for interventionists and have high restenosis rates. Proper placement of the stent is critical for prevention of future complications in these lesions. We describe a case in which the ostial right coronary artery stent with severe in-stent restenosis was protruding too far into the aorta, causing significant difficulty in engaging the guidewire in the true lumen. The stenosis was finally tackled through the side of the stent and the restenosis was successfully restented.
