|A 69-year-old male patient was hospitalized for dyspnea, NYHA functional class III. He has a past medical history of Behcet¡¯s disease and permanent pacemaker implantation due to complete AV block. And He underwent Bentall operation with 25 mm sized Prima bioprosthetic aortic valve due to periaortic abscess 16 years ago. There was no significant coronary artery stenosis on coronary angiogram. Electrocardiography showed paced rhythm. The Society of Thoracic Surgery risk score, EuroSCORE I, and EuroSCORE II were 2.908%, 21.00%, and 5.62%, respectively.|
|Considering the annulus size by CT, we planned to use 26-mm Evolut R valve through right femoral artery. Under general anesthesia, 6 Fr sheath and temporary pacemaker were inserted through left femoral vein, and 7 Fr sheath and 6 Fr pig-tail catheter were inserted through left femoral artery. After both peripheral angiogram with pig-tail catheter, we checked proper puncture site of right femoral artery. 8 Fr sheath was inserted through right femoral artery and preclosure with one Proglide device was done. And then, the right femoral artery was dilated and 18 Fr Sentrant sheath was inserted. An AL 1 diagnostic catheter with a 0.035 inch Amplatz stiff wire was used to cross the aortic valve. Aortic root angiography was done ( Movie 1). Under fluoroscopy control, the 14 Fr Evolut R delivery catheter system was advanced gently into the vessel. The Evolut R crossed over pre-existing stent-less valve using the super-stiff wire and deployment was done ( Movie 2). After valve implantation, final fluoroscopy showed well positioned Evolut R valve without significant AR. ( Movie 3). After the intervention, puncture site was closed by prepared Proglide device.|
