Article Synopsis
- Interventional closures of atrial septal defects (ASDs) and paravalvular leaks can help avoid surgery, but complications can still arise requiring further surgical intervention.
- Three cases highlighted include a 73-year-old man with a mechanical mitral valve experiencing hemolysis, a 21-year-old woman with prior heart surgeries needing additional treatment due to paravalvular leakage, and a 24-year-old woman requiring a fourth valve replacement after severe hemolysis post-closure.
- Six additional cases involved the removal of occluders due to issues like dislocation and allergic reactions, but all surgeries and recoveries were successful, indicating that while challenging, outcomes can be positive with future advancements in device technology.
Objectives: Do prior percutaneous coronary interventions adversely affect the outcome of subsequent coronary artery bypass grafting? We investigated this effect on a multicenter basis.
Methods: Eight cardiac surgical centers provided outcome data of 37,140 consecutive patients who underwent isolated first-time coronary bypass grafting between January 2000 and December 2005. Twenty-two patient characteristics and outcome variables were retrieved.
Background: Few reliable data are available on clinical outcome of octogenarians undergoing simultaneous aortic and mitral valve replacement.
Methods: We performed a retrospective analysis of 55 patients aged 80 years and over with double valve replacement who were operated on at our institution between 2001 and 2005. Thirty-day mortality and 1-year survival were assessed.
Selective adhesion of plasma proteins to immobilized heparin is considered to be beneficial regarding hemocompatibility of foreign materials in contact with blood. Prothrombin, thrombin, antithrombin III (AT3), and fibrinogen were selected for analysis in an experimental model. Biomolecular interaction analysis employing surface plasmon resonance was utilized to record and analyze their binding properties in real time.

The current surgical management and the results of aortic valve replacement are outlined. The presented results of aortic valve replacement especially in elderly and high-risk patients compare favorably with other published data in respect to perioperative morbidity and mortality.

The long-term follow up of patients who underwent isolated TVR at the authors' institution was analyzed.
Methods: All patients (n = 107) who underwent TVR between January 1985 and December 2002 were identified from a clinical database.
Background: Diabetes mellitus is not only an independent risk factor for the development of arteriosclerosis, but also a risk factor for the surgical and interventional treatment of coronary artery disease (CAD).
Patients And Methods: In 2003, a consecutive series of 2,142 patients underwent isolated coronary bypass grafting at the authors' institution, 567 of these suffering from diabetes mellitus.
Results: An analysis of the diabetic and nondiabetic patients revealed a more pronounced risk profile, a significantly reduced left ventricular function and a significantly poorer quality of the coronary arteries in the diabetic group.
Background: The revascularization of patients suffering from ischemic cardiomyopathy is possible with acceptable perioperative mortality and morbidity. Many publications have discussed the problem of predicting myocardial viability, whereas the quality of the peripheral coronary vessels has been focused on less frequently.
Methods: We studied 908 consecutive patients with ischemic cardiomyopathy revascularized between January 1, 1988 and April 30, 2000.
