Abstract

Abstract: Background: Selective cannulation must be ensured especially in patient with coronary artery disease (CAD). Commissural alignment in self-expanding transcatheter heart valve (THV) is fundamental to facilitate subsequent coronary reaccess. Clinical Scenario: A man of 84 years old, suffering from hypertension, dyslipidemia, diabetes mellitus, third stage of chronic kidney disease and obesity was admitted in our hospital for treatment. He had angina and dyspnea with a third NYHA class. The echocardiogram showed severer aortic stenosis with mean gradient of 48 mmHg and aortic valve area of 0.6cmq with preserved ejection fraction. He was eligible for transfemoral transcatheter aortic valve implantation (TAVI) and he had intermediate risk score. The preprocedural coronary angiogram revealed subocclusive and severe calcified lesion on mid circumflex artery. Methods: The Acurate NEO 2 size L THV was chosen and was planned to implant the bioprosthesis with commissural orientation correlated to the native commeasures, selecting at the CT scan the projection of cusp overlap (right and left coronary cusp on the right of the screen). The delivery catheter was inserted into the introducer sheath with its flush port facing the six o'clock position and the after crossing the aortic arch and native annulus, the handle of the delivery catheter was torqued clockwise until 1 of the Acurate NEO 2 commissural posts faced the commissural of the aortic root. The final angiogram showed optimal position and orientation of the THV without paravalvular leak. The patient was discharged the next day with a mean gradient of 9mmHg. One month after TAVI, elective PCI was performed. We've prepared the lesion with rotational atherectomy, due to severe calcification. Three forward advancements of rotating abrasive burr was performed and subsequently one DES was implanted. The angiogram check showed excellent result with TIMI 3 flow. Conclusion: The Acurate Neo 2 supra-annular valve platform provides a successful coronary cannulation. Coronary rotational atherectomy for severe calcified lesions after TAVI with Acurate Neo 2 is a feasible strategy
