[Tumors of the heart. 16 years experience in Hospital de Cardiología, del Centro Médico Nacional Siglo XXI in Mexico City]. / Tumores cardíacos. Experiencia de 16 años en el Hospital de Cardiología del Centro Médico Nacional Siglo XXI.

INTRODUCTION: We present incidence of primary cardiac tumors diagnosed from 1987 at the Hospital de Cardiología, Centro Médico Nacional Siglo XXI, in Mexico City. OBJECTIVE: We described primary cardiac tumors based on histopathologic diagnosis, frequency, localization, implantation, implantation site, and recurrence. MATERIAL AND METHODS: A total of 51 patient files were selected retrospectively. Patients underwent cardiothoracic surgery with primary cardiac tumor established by clinical and echocardiographic parameters with histopathologic corroboration between 1987 and 2002. Statistical analysis of obtained results show frequency, central tendency and standard deviation. RESULTS: Primary cardiac tumors were benign in 84% and malignant in 16%. Among benign tumors, myxoma was present in 74%, (38 cases) followed by papillary fibroelastoma in 6% (three cases); finally, there were two cases (4%) of fibroma. Malignant tumors belonged to two hemangioendothelioma cases (4%) and there were 6 cases of sarcoma (12%). Main affected gender was female in 61%. All cases were taken to surgical resection. There was recurrence four times (8%) belonging to three myxomas and one sarcoma. Average presentation age was 43 +/- 17 years. Cardiac primary tumors represent 0.16% of surgeries taking place at our service. Concordance was found with previous studies regarding frequency, gender, age, localization, and implant site of cardiac primary tumors with greater recurrence in our series.

[Surgery induced neurologic damage of myocardial revascularization with extracorporeal circulation]. / Daño neurológico secundario a cirugía de revascularización miocárdica con circulación extracorpórea.

OBJECTIVE: Our objective was to describe incidence of neurologic damage in patients who experienced coronary revascularization with cardiopulmonary bypass during cardiothoracic surgery. MATERIAL AND METHODS: Clinical charts of patients who experienced coronary revascularization were chosen retrospectively. Some patients were excluded because their charts were incomplete. We searched for clinical evidence of neurologic damage after the surgical procedure; this was based on Glasgow scale, complementary tests, and some risk factors. Statistical results analysis were presented in frequencies, tendency of central measurements and standard deviation. RESULTS: We carried out 384 myocardial revascularizations in 1 year; 44 were excluded. We analyzed 340 charts with incidence of neurologic complications of 2.6% (9 cases of 340), and two cases (0.5%) with severe damage; one patient died. Incidence and type of complications that we found agree with the literature. Limitations exist because it was a retrospective study and evaluation was done only clinically considering only major neurologic damage and no neuropsychologic damage.
