Background: Hemopericardium is a serious complication that can occur after cardiac surgery. While most post-operative causes are due to inflammation and bleeding, patients with broken sternal wires and an unstable sternum may develop hemopericardium from penetrating trauma.

Case Presentation: We present the case of a 62-year-old male who underwent triple coronary bypass surgery and presented five months later with sudden anterior chest wall pain.

Background And Aim Of The Study: Aortic valve dysfunction is the most common form of valvular heart disease. As the population continues to age, a greater number of patients will become candidates for aortic valve replacement (AVR); hence, prosthetic valve choice becomes of paramount importance.

Methods: A retrospective analysis was conducted on 801 patients aged > or =65 years who underwent isolated AVR or AVR + coronary artery bypass grafting (CABG) between January 1989 and June 2003 with a Carpentier Edwards Perimount (CEP) pericardial bioprosthesis (n = 398) or a St.

Anticoagulation with unfractionated heparin has been the standard of care for more than a half-century for patients undergoing cardiac surgery. The risk of heparin-induced adverse reactions dictates the need for a safe and effective alternative, particularly in off-pump coronary artery bypass (OPCAB) surgery, an approach associated with a perioperative prothrombotic condition that may negatively influence graft patency. Between March 2003 and January 2005, 243 consecutive patients underwent OPCAB with bivalirudin (0.

Background And Aim Of The Study: The selection of a suitable valve substitute in patients requiring valvular heart surgery is an important element in the preoperative decision-making process between cardiologist, surgeon, and patient. Controversy persists regarding the use of mechanical valves in the elderly. With the population living longer, reoperative risk becomes of paramount importance.

Background: Mitral valve reconstruction using standardized Carpentier techniques is the treatment of choice for most patients with regurgitant lesions. Demonstrated predictability and stability make it an attractive alternative to valve replacement. The Physio Ring's inherent flexibility provides a viable alternative in the application of remodeling techniques and appears to be physiologically superior to traditional approaches.

Background: Heparin-induced thrombocytopenia (HIT) is a potentially devastating complication of heparin therapy. The incidence of clinical HIT after cardiovascular surgery is less than 2%, although asymptomatic antibodies to heparin-platelet factor 4 (PF4) occur more frequently. Bovine heparin is thought to cause more HIT than porcine heparin, although this has never been established for heparin use during coronary artery bypass grafting.
