      Abstract:

      An 83-year-old gentleman underwent transcatheter aortic valve replacement using a 34-mm Evolut R valve. Considering the residual mean gradient (19 mmHg) and the presence of the string sign, post-dilatation was performed. The infolding persisted on fluoroscopy but the final mean gradient was 9 mmHg. At 30-day follow-up, transeosophageal echocardiography and CT scan showed a heart-shaped prosthesis inflow. Follow-up at 3 years did not show any sign of early structural valve deterioration.
