Continuous-wave Doppler recording of the aortic valve (AV) in 5-chamber view (a and b) and of the apical conduit opening at the insertion site with the left ventricle (LV; c and d). a, Baseline: A mean transvalvular gradient across the native AV of 34 mm Hg and velocity of 3.5 m/s were evident at rest, which corresponded with 1.7 L/min of cardiac output across the AV. b, Dobutamine (40 µg/min): A mean transvalvular gradient of 50 mm Hg and velocity of 4.8 m/s were evident at peak dobutamine across the native AV, which corresponded with a flow increase to 4.3 L/min. c, Baseline: A mean transvalvular gradient of 2 mm Hg was detected at the apicoaortic conduit opening at the LV insertion site. d, Dobutamine (40 µg/min): A mean transvalvular gradient of 3.4 mm Hg at peak dobutamine was detected at the apicoaortic conduit opening at the LV insertion site, which corresponded with a flow increase across the conduit from 2.3 to 4.7 L/min.

An angiogram of the distal portion of the apicoaortic conduit (distal to the prosthetic Hancock prosthesis inside the conduit) using an end-hole 5F Judkins right catheter (JR4). A 6F double-lumen pigtail catheter is see in the LV across the native aortic valve demonstrating (which showed a transvalvular mean gradient of 38 mm Hg). A gradient between the LV and the distal limb of the apicoaortic conduit of 12 mm Hg was measured before the angiogram.Show Less

An angiogram of the distal portion of the apicoaortic conduit using the JR4 catheter demonstrating a significant 80% diameter stenosis at the anastomosis site. A slow pullback of the JR4 catheter was subsequently performed from the distal limb of the apicoaortic conduit into the aorta and demonstrated a 40-mm Hg gradient across the anastomosis site.Show Less

An ECG-gated thin slice contrast-enhanced computed tomography (CT) scan showing severe stenosis at the distal anastomosis site of the apicoaortic conduit as it enters the descending aorta. A cross-section of the anastomosis site by contrast cardiac CT (not shown) confirmed significant narrowing along with severe calcification and fibrosis at this site.Show Less
