[Surgery of complex congenital cardiopathies].

The present is a brief report about the advances in treatment of complex congenital heart defects at our institution, including the importance of prenatal detection, improved perioperative management, the surgical technique, the anesthesia control extended into the postoperative period, the extraordinary advances in cardiopulmonary bypass technology, and postoperative management. The operative mortality now is low for many cardiac defects, as result of a team of experienced surgeons, anesthesiologists, cardiologists, and nurses working together in the treatment of these patients. The issue of concern is now on the assessment of hemodynamic and neurodevelopmental status in the long-term follow-up. Further improvements in the surgical management of infants with complex congenital heart defects are required, and evaluation of these new techniques will likely come from prospective, randomized trials with large patient cohorts and long-term follow-up.

[Giant intracardiac Rhabdomyoma in neonatal stage. Report of one case].

Primary heart tumors are not very common, frequent ones during childhood are the rhabdomyomas. This diagnostic can be made since fetal life. Evolution variates, in some cases there are no symptoms and the diagnostic represents an echocardiographic finding, other cases are detected associated with tuberous sclerosis and a small group express by arrhythmias or low output. Because of the strange of this presentation this case is presented.

[Intracardiac echocardiography (ICE) in the operating room as a support measure in the evaluation of immediate surgical results in congenital cardiopathies].

The utilization of intracardiac echocardiography (ICE) is a recent alternative in the control of procedures in the Cath Lab. In this paper we presents the results of a pilot study, in 10 patients submitted to total correction of its congenital heart disease, in who the analysis of the surgical results was done in base to the application of intracardiac echocardiography in operations room. In all the patients it was possible to obtain adequate images with ICE, there was a case false negative, a Total anomalous return Pulmonary Veins, in whom there not indentified a obstruction in right pulmonary veins flow. We conclude that ICE is a good alternative in the evaluation of surgical results.

[Left ventricular myxoma].

Primary tumors of the heart are rare entities. We report a unique case of a young woman presenting a left ventricular myxoma, which manifested itself as coronary artery disease and was diagnosed by echocardiography. Emergency surgical treatment was indicated, done through a transeptal approach with extensive resection of the tumor, its pedicle and the papilar muscle to which it was attached as well as the anterior mitral leaflet, which was thinned and deformed by the presence of the mass. Mitral valve replacement was mandatory. A complete retrospective review of the literature is presented.

[Sugical treatment of aortic coarctation. Long-term results at National Institute of Cardiology of Mexico].

OBJECTIVES: Evaluate long-term evolution of patients submitted to surgery for coarctation of the aorta. Compare event free survival in younger vs older patients at the time of surgical correction. METHODS: We reviewed the clinical records of patients operated for coarctation of the aorta from January 1 1980 to December 31 1994. The mean follow-up ranged from 9 to 23 years (mean 10.9 y). Final events registered were recoarctation, death, systemic hypertension, endocarditis, stroke, aneurisms. RESULTS: Two hundred and sixteen patients were found with mean age 13 +/- 12 y male gender was most frequent (61%). Recoarctation was found in 13 patients (6.02%), persistent hypertension in 14.1%. Event free survival at 10 years was 86.2%. In patients less than 10 y was 89% vs 80.2% in older patients. Hypertension free survival in patients less than 10 y was 98.3% vs 80.1% in older patients (p < 0.001). CONCLUSIONS: Our data confirms that surgical treatment for coarctation of the aorta is associated with low morbidity and mortality at long-term with reduced rate of recoarctation (7%). Early correction (< 10 y) is associated with a better long term survival. Hypertension and use of pharmacologic treatment are reduced after surgery and persist in the long-term evolution.
