Many congenital heart conditions that were previously considered to be inoperable are now able to be corrected surgically. As a result, a more accurate and refined "surgical diagnosis" than that offered by conventional angiography has been sought. Axial cineangiography is invaluable in establishing a specific diagnosis in such cases.
Cineangiographic axial techniques were designed to overcome the limitations of conventional angiography in the diagnosis of congenital heart disease. Two basic patient (or equipment) maneuvers are involved; 1) long axis of the heart is aligned perpendicular to the X-ray beam, and 2) rotation of patient results in the heart being radiographically sectioned(More)
Eighty-six adult patients were studied by PA chest film and fluoroscopy for coronary artery calcification (CAC). A triangular area (CAC triangle) along the left mid-heart border of the PA chest film was used in identifying CAC. Of 57 patients, 24 (42%) with CAC observed fluoroscopically had a strongly suspected or positive CAC triangle. The CAC triangle in(More)
An angiographic analysis of 10 cases of univentricular heart of the right ventricular type is reported. This congenital malformation is characterized by a large chamber with right ventricular morphology that receives both atrioventricular valves, and a second, smaller chamber, a trabecular pouch, with left ventricular morphology. These chambers are(More)
The value of axial cineangiography in several forms of congenital heart disease serves as an illustrated supplement to Section I. These techniques visualize defects in the entire ventricular and atrial septum. In persistent atrioventricular (A-V) canal, it is possible to visualize all parts of both septa, status of the A-V valves (two valves versus a common(More)
Three cases of anatomically corrected malposition of the great arteries (ACM) are presented. The association of ACM with juxtaposition of the atrial appendages and right aortic arch is emphasized. The unique plain film findings of anatomically corrected malposition include: (a) 1-position of the ascending aorta; (b) discrete convexity of the mid-left heart(More)
Digital mammography can potentially improve mammography image and interpretation quality. On-line interpretation from a workstation may improve interpretation logistics and increase availability of comparison images. Interpretation of eight 4k- × 5k-pixel mammograms on two to four 2k- × 2.5k-pixel monitors is problematic because of the time spent in(More)
The authors describe the value of the caudal left-anterior-oblique view in visualizing the following arteries: left main coronary, proximal circumflex, early-arising first marginal, proximal left anterior descending, first diagonal, and anomalous septal perforators from the circumflex system. The technique involves movement of the parallelogram (x-ray(More)
BACKGROUND The Hemodialysis Reliable Outflow (HeRO) dialysis access device is a permanent tunneled dialysis graft connected to a central venous catheter and is used in patients with end-stage dialysis access (ESDA) issues secondary to central venous stenosis. The safety and effectiveness of the HeRO device has previously been proven, but no study thus far(More)
