The use of 25% glutaraldehyde solution to strengthen the aorta of patients with annuloaortic ectasia, ascending and aortic arch aneurysms.
Aortic friability is a problem of great concern and frustration for those performing operations on patients with ascending and arch aortic aneurysms, and particularly, on patients with annuloaortic ectasia. We have used 25% glutaraldehyde to successfully strengthen the distal aorta of three such patients. After the application, the aorta wall held sutures without tearing. Postoperative bleeding was minimal in each case. No neurological events were noticed, and all of the patients were discharged home within 2 weeks. The application of this tanning solution to such a friable aortic tissue should be considered as a helpful alternative to reduce postoperative bleeding, which is the most common complication after this type of surgery.

Coronary artery bypass grafting in patients with systemic lupus erythematosus. Report of 2 cases.
Systemic lupus erythematosus is an autoimmune disease that often involves the cardiovascular system. Coronary artery narrowing in patients with lupus erythematosus is severe, progressive, and related to the duration of the disease rather than to the age of the patient. Steroid use in such patients has improved their life expectancy but seems to be increasing the incidence of coronary involvement. Consequently, a larger number of systemic lupus erythematosus patients may be candidates for myocardial revascularization in the future. We report our experience with myocardial revascularization in 2 women with severe systemic lupus erythematosus, incapacitating angina, and severe obstructive coronary artery disease. One of the women required balloon angioplasty 19 months after coronary artery bypass grafting and remains asymptomatic nearly 3 years later. The other patient is free of symptoms 9 months after surgery. Our results with these 2 patients are encouraging. Long-term follow-up should yield further information regarding the benefits of myocardial revascularization and coronary angioplasty in patients with systemic lupus erythematosus.

Right coronary artery with anomalous origin and slit ostium.
Right coronary arteries that arise from the left sinus or ectopically from the right sinus with a slit ostium can cause myocardial ischemia, myocardial infarction, or sudden death. The surgical repair of these anomalies has evolved toward a simpler operation that widens the orifice of origin and reduces the compression of the intramural segment. We have repaired these anomalies without mortality in 8 patients. We summarize our experience and the evolution of this procedure.
