Abstract
Introduction

Cardiac myxomas account for 50% of all benign cardiac tumors. Their clinical presentation varies from embolisms to fever. Our objective was to describe the surgical experience in the resection of cardiac myxomas during an 8-year period.

Methods

This is a retrospective, descriptive study of a series of cases with cardiac myxomas diagnosed from 2014 to 2022 at a tertiary care center. Descriptive statistics were used to define the populational and surgical characteristics. We used Pearson’s correlation to study the relationship between postoperative complications and age, tumor size and affected cardiac chamber.

Results

31 patients were included, with a predominance of females (1:2 ratio). The prevalence was 0.44%, which was calculated based on the number of cardiac surgeries performed in our unit over the 8-year period. The main clinical manifestation was dyspnea (85%, n = 23), followed by cerebrovascular event (CVE) (18%, n = 5). Atriotomy and resection of the pedicle were performed with preservation of the interatrial septum. Mortality was 3.2%. The postoperative evolution was uneventful in 77%. Tumor recurrence occurred in 2 patients (7%), both debuting with embolic phenomena. No association was observed between postoperative complications or recurrence and tumor size, nor aortic clamping and extracorporeal circulation times with regard to age.

Conclusions

Four atrial myxoma resections are performed in our unit per year, with an estimated prevalence of 0.44%. The tumor characteristics described coincide with the previous literature. A relationship between embolisms and recurrences cannot be ruled out. Wide surgical resection of the pedicle and base of tumor implantation may influence tumor recurrence, although further studies are needed.

Resumen
Introducción

Los mixomas cardíacos representan el 50% de los tumores cardíacos benignos. La presentación clínica varía desde embolismos hasta fiebre. El objetivo fue describir la experiencia quirúrgica en la resección de mixomas cardíacos durante 8 años.

Métodos

Estudio retrospectivo, descriptivo, de serie de casos de mixomas cardíacos diagnosticados entre 2014 y 2022 en un centro de tercer nivel. Se utilizó estadística descriptiva para definir las características poblacionales y quirúrgicas. Mediante la correlación de Pearson se estudió la relación entre las complicaciones postoperatorias y la edad, el tamaño del tumor y la cavidad cardiaca afectada.

Resultados

Se incluyeron 31 pacientes, predominantemente mujeres (1:2). La prevalencia fue 0.44%, calculada en base a las cirugías cardíacas realizadas en nuestra unidad durante 8 años. La principal manifestación fue disnea (85%, n = 23), seguida de EVC (18%, n = 5). Se realizó atriotomía y resección del pedículo con preservación del tabique interauricular. La mortalidad fue del 3.2%. La evolución posquirúrgica fue adecuada en el 77%. La recidiva ocurrió en 2 pacientes (7%), debutando ambos con embolismos. No se observó asociación entre las complicaciones postoperatorias o recurrencia y el tamaño tumoral; ni en pinzamiento aórtico y los tiempos de circulación extracorpórea con respecto a la edad.

Conclusiones

En nuestra unidad se realizan cuatro resecciones de mixoma auricular anuales (prevalencia de 0.44%). Las características tumorales descritas coinciden con la literatura previa. No se descarta relación entre embolismos y recurrencias. La resección amplia del pedículo y base del tumor puede influir en la recurrencia tumoral, aunque, se requieren más estudios.
