Recurrent Trichosporon beigelii endocarditis after aortic valve replacement.

Fungal endocarditis of the bioprosthetic heart valve, implanted in a patient without evidence of impaired immunity, is reported. Clinical manifestations of endocarditis appeared 7 years after aortic valve replacement for rheumatic disease and included embolization into the popliteal artery. Trichosporon beigelii was isolated from the cultured fragments of the embolus. Two valve replacements were performed because of recurrent infection during the following 4 years. In spite of prolonged antifungal therapy, the patient died from multiorgan septic involvement.

Cardiopulmonary bypass in HIV-positive patients.

To prove the hypothesis that cardiopulmonary bypass may accelerate the development of acquired immunodeficiency syndrome (AIDS) in the human immunodeficiency virus carrier, the clinical course of 40 patients positive for human immunodeficiency virus who underwent cardiac operations between 1986 and 1992 was analyzed, especially in regard to the progression to AIDS. Mean age was 30 years (range, 19 to 61 years). Thirty-four patients (85%) were intravenous drug abusers; in 4 (10%) transmission of infection was sexual, and in 2 (5%) it was through a contaminated blood transfusion. Valve procedures were performed in 38 patients (95%), mostly for endocarditis in drug addicts. Hospital mortality was 20% (8 patients). The 32 survivors have been followed up a mean of 21 months (range, 4 months to 6 years). Four patients (12.5%) experienced progression to AIDS during the follow-up period. Actuarial progression to AIDS is 5% (+/- 5%) at 1 year, 20% (+/- 10%) at 2 years, and 40% (+/- 19%) at 5 years. There have been 8 late deaths (5 due to recurrent endocarditis, 2 due to AIDS, and 1 due to overdose). Actuarial survival is 79% (+/- 8%) at 1 year, 60% (+/- 11%) at 2 years, and 48% (+/- 14%) at 5 years. The results indicate that progression to AIDS in the patient positive for human immunodeficiency virus is not accelerated by the use of cardiopulmonary bypass. The poor prognosis in these patients is mainly related to the particular pathological conditions that often affect the drug addict population.

[The National Data Bank of the Spanish Society of Cardiovascular Surgery. The pilot experience].

Since 1988, the Spanish Society of Cardiovascular Surgery has been enjoying through its National Intervention Registry a complete information about the number and type of cardiovascular surgical operations, yearly performed all over the country. However a computerized National Data Bank would probably offer a more specific, quick and complete information, although its organization is more complex. We want to demonstrate that the creation of a National Data Bank is possible in our country. The following condition has been essential to carry out this initial work on the National Data Bank: The previous existence of a National Intervention Registry, the edition of an universally accepted questionnaire of 33 questions with multiple answers for each question, which includes quantitative and qualitative aspects like mortality, the acquisition of the software Pats Programme by most cardiovascular centers, and finally the enthusiastic dedication of 6 surgical groups. The results of this work also shown in multiples figures, are the final product of the computerized fusion of 6 cardiovascular centers data on operations performed through the year 1991. The results clearly offer a more specific, detailed and extensive information about quantitative and qualitative aspects of the surgical data, than that obtained through the National Intervention Registry. These results should not be extrapolated at national level, as the surgical groups involved in this work are not homogeneous and its number is quite small. This initial study shows that the creation of the National Data Bank of the Spanish Society of Cardiovascular Surgery or other scientific society is possible in our country. Its usefulness is beyond any doubt.

Cardiac myxomas: surgical treatment, long-term results and recurrence.

Long-term results of the surgical treatment of cardiac myxomas are not completely understood due to its recurrence. We review our experience in 27 operated cases with a follow-up to 22 years (mean 6.5 years), in order to throw light on results and review the problem of recurrence. One patient had a previous recurrent myxoma. At surgery we resect all the tumors and their attachment bases. We prefer a biatrial approach, ample resection and exploration of all cardiac chambers. Hospital mortality was 3.7% (1 case of associated aortic valve replacement) and late mortality 7%. Long-term results were satisfactory, without recurrences. The postoperative life expectancy of these patients seems similar to that of the normal population, except in cases of recurrence or associated valve replacement. Recurrence is very low (4.7% in 526 cases reported in the literature), except in the case of young patients and recurrent, familial, multiple or complex myxomas. The multigrowth potential of the tumor seems more important than an inadequate surgical resection.

Constrictive pericarditis after heart transplantation: report of two cases.

We report two cases of constrictive pericarditis after heart transplantation. It is noteworthy that constriction developed after a healed intrathoracic infection in the two patients. Unlike previous reported experiences, pericardiectomy was uneventful and successfully performed, although incomplete improvement was achieved in one case.
