1. Sinus of Valsalva Aneurysm of the Non-Coronary Cusp

Abstract

Aneurysms of the sinuses of Valsalva, when detected before rupture, are repaired electively. When they are small, they are most frequently repaired by direct closure; when they are large, they are repaired with a prosthetic patch. When they are associated with prolapse of the corresponding aortic cusp and aortic insufficiency, valve replacement is usually performed concomitantly. We present the case of a patient in whom both abnormalities were corrected by implantation of a Freestyle® bioprosthesis, the wall of which completely excluded the aneurysm of the sinus of Valsalva. The patient remains asymptomatic 18 months after surgery. (Tex Heart Inst J 2003;30:202–4)

28. Experimental folding of rocks under confining pressure: Part VII. Partially scaled models of drape folds

Author

Weinberg, David M.

Abstract

Drape folds are created experimentally at 0.5 kb confining pressure and displacement rates of 6.6 · 10 −3cm/sec by displacement of a steelblock forcing-assembly (2 by 3 by 12 cm) along lubricated, arcuate, precut surfaces into a veneer of two to six initially intact layers (variable thicknesses to nearly 1.3 cm by 11 cm long) of chalk (ductile), dolomite (brittle), lead (ductile), limestone (ductile), and sandstone (brittle). Various forcingmember configurations produce a wide variety of fault-fold systems, several of which are produced during a single test.
