13. Degenerative changes in aortic root allografts placed in the right ventricular outflow tract of growing puppies.
Differently prepared aortic root allografts were implanted in the right ventricular outflow tract of growing puppies to determine the site of origin and progress of degenerative changes in these conduits. The three preparations assessed were as follows: group A, fresh and sterile grafts; group B, antibiotic sterilized grafts in nutrient medium; and group C,

14. Idiopathic infantile arterial calcification in two siblings: failure of treatment with diphosphonate.
Two siblings with idiopathic infantile arterial calcification are reported. The fetal and postnatal echocardiographic features were a large pericardial effusion, thickened pulmonary and aortic valves, poor pulsation of the descending aorta, and calcification of the great vessels. In one patient calcification was first detected at 33 weeks' gestation. Despite

15. Unusual findings of asymmetrical septal hypertrophy associated with calcification of the interventricular septum: Case report
A patient with aortic regurgitation, stenosis, and calcification of the septum is reported. Results of echocardiography revealed asymmetrical septal hypertrophy without other features of idiopathic hypertrophic subaortic stenosis. There was no subaortic obstruction evident on cardiac catheterization and angiography. This case serves to emphasize that calcifi

20. Vitamin K-dependent Calcium Binding Proteins in Aortic Valve Calcification
The pathogenesis of valvar calcification, which complicates the course of cardiac valve disease and also affects tissue valve prostheses, is incompletely understood. The present work explores the possible role of the vitamin K-dependent, calcium-binding amino acid, γ-carboxyglutamic acid (Gla) in valve mineralization. Gla is normally found in the vitamin K-

21. Technetium-99m stannous pyrophosphate scintigraphy in patients with calcification within the cardiac silhouette.
Technetium-99m stannous pyrophosphate scintiscanning was performed in 22 patients with radiographically detected calcification within the cardiac silhouette. All but one of these scintigrams showed a localised area of increased activity similar to that ordinarily seen in acute myocardial infarction. Scintiscans in 3 patients after removal of the calcified ao

22. Surgical techniques for aortic valvuloplasty.
Since 1988, reparative techniques have been used at our institution to treat valvular insufficiency in selected patients with aortic valve disease. The limitations of aortic valve replacement are well recognized; it is this knowledge that has motivated us to find out whether a subgroup of patients who have aortic insufficiency might be candidates for preserv

23. CREATION OF A SECONDARY VENTRICULAR OUTLET TO REVERSE HEMOLYSIS AFTER AORTIC VALVE REPLACEMENT
A 66-year-old woman developed severe hemolysis after undergoing aortic valve replacement. A diminutive annulus and extensive calcification of the aorta precluded further surgery of the aortic root. Hemolysis was completely reversed by the implantation of a woven Dacron apicoabdominal aortic conduit incorporating a Cooley-Cutter prosthetic valve. Fractionatio

24. Osteopontin mRNA is expressed by smooth muscle-derived foam cells in human atherosclerotic lesions of the aorta.
Osteopontin is a phosphorylated, sialic acid-rich, noncollagenous bone matrix protein containing the Arg-Gly-Asp-Ser amino acid sequence responsible for cell adhesion. The protein strongly binds to hydroxyapatite and play an important role in calcification. Expression of osteopontin mRNA was analyzed in human aortic atherosclerotic lesion by Northern blot hy
