After-procedure evaluation. (a) Short-axis frames from a cine-phase contrast scan depict the blood flow through the aorta and atria after trocar removal and chest closure. These scans are used to confirm adequate valve opening and blood flow through the prosthetic valve and identify intra- or paravalvular regurgitation. Left: diastole. Right: systole. (b) A first-pass perfusion scan was performed during intravenous injection of Gd-DTPA contrast agent to confirm that myocardial blood flow was intact to all segments of the myocardium. From left to right the progression of time after venous injection of Gd-DTPA is represented.
