Sterile Necrosis of the Sternum: A Rare Complication Following Coronary Artery Bypass Surgery.

We herein present the unique case of a 68-year-old male diabetic patient who developed sterile necrosis of the sternum 1 month after myocardial revascularization with the use of bilateral internal thoracic artery grafts. The sternum had been closed by the bilateral Robicsek wiring technique. The sternum was removed, and bilateral pectoralis major flaps were used to cover the defect.

Repair of Tricuspid Valve Leaflet With CardioCel Patch After Traumatic Tricuspid Regurgitation.

Posttraumatic tricuspid valve regurgitation (TR) is a rare entity and is almost always associated with blunt chest trauma. It is usually identified by transthoracic echocardiography after the manifestation of clinical symptoms of heart failure. Treatment varies from long-term medical therapy and observation to surgical correction with tricuspid valve replacement or repair.

TLR-4 and CD14 Genotypes and Soluble CD14: Could They Predispose to Coronary Atherosclerosis?

Background: Inflammatory mechanisms are key to the pathogenesis of atherosclerosis. Functional polymorphisms of TLR-4, Asp299Gly and Thr399Ile, CD14 promoter area C260T polymorphism and plasma levels of soluble CD14 are studied in subjects with Coronary Artery Disease (CAD).

Methods: DNA was obtained from 100 human paraffin-embedded aortic specimens, from cadavers with known coronary atheromatosis (Group A) and 100 blood samples from patients with CAD, as detected by cardiac Multi-Detector-row-Computed-Tomography (MDCT) (Group B).
