Cine Loop SG1 through S4F

Cine loops SG1 through S4F

Files in this Data Supplement:

• S1G - Cine loop shows serial images parallel to plane in 1A. Ao = aorta, CS = coronary sinus, IVC = inferior vena cava, LV = left ventricle, LVOT = left ventricular outflow tract, PA = pulmonary artery, RA = right atrium, RAA = right atrial appendage, RV = right ventricle, RVOT = right ventricular outflow tract, SVC = superior vena cava.
• S1H - Cine loop corresponding to Figure 1B shows serial images parallel to plane. Arrows indicate two metallic points on device, which can ensure perpendicularity between plane and device. Ao = aorta, CS = coronary sinus, IVC = inferior vena cava, LA = left atrium, LV = left ventricle, LVOT = left ventricular outflow tract, RA = right atrium, SVC = superior vena cava.
• S1I - Cine loop corresponding to Figure 1C shows dynamic motion in four-chamber view during heart cycle. Device is placed properly without interfering with coaptation of mitral valve.
• S1J - Cine loop corresponding to Figure 1D shows dynamic compression with near total occlusion in diastole and no compression in systole. Findings emphasize importance of evaluating images dynamically.
• S1K - Cine loop corresponding to Figure 1E shows superior vena caval to right atrial tract and Amplatzer septal occluder during heart cycle.
• S2D - Cine loop corresponding to Figure 2B shows serial sections in oblique axial plane. Arrowheads indicate mild compression of coronary sinus. Ao = aorta, LA = left atrium, LAA = left atrial appendage, LV = left ventricle, LVOT = left ventricular outflow tract, PA = pulmonary artery, RA = right atrium, RAA = right atrial appendage, RV = right ventricle, SVC = superior vena cava.
• S2E - Cine loop corresponding to Figure 2C shows serial sections in oblique sagittal plane. Ao = aorta, LA = left atrium, LVOT = left ventricular outflow tract, RA = right atrium, RAA = right atrial appendage, SVC = superior vena cava.
• S3C - Cine loop corresponding to Figure 3A. Ao = aorta, CS = coronary sinus, IVC = inferior vena cava, LA = left atrium, RA = right atrium, RV = right ventricle, SVC = superior vena cava.
• S3D - Cine loop corresponding to Figure 3B shows cardiac motion during heart cycle. If it interferes with normal coaptation of mitral valve, device should be removed. This case emphasizes that if selected properly, even large occluders can be used safely. Important factors are adjacent structures and relative size compared with defect, not absolute size of device.
• S4E - Cine loop shows serial sections on same plane as Figures 4A and 4B. Ao = aorta, CS = coronary sinus, IVC = inferior vena cava, LA = left atrium, LVOT = left ventricular outflow tract, RA = right atrium, SVC = superior vena cava.
• S4F - Cine loop corresponding to Figure 4D shows short-axis sections. Black arrows indicate left ventricular trabeculation. C = compaction layer (arrowheads), LV = left ventricle, NC = noncompaction layer (white arrow), RV = right ventricle
