Mixoma cardíaco: experiencia clínica de 8 años en una clínica cardiovascular

Abstract

IntroductionThe primary cardiac tumours are a rare entity. The myxomas are the most common cardiac tumours, with an incidence of 50% to 70%. The aim of this study is to describe the clinical presentation, comorbidities, surgical and post-surgical management, as well as morbidity and mortality of patients with cardiac myxoma who were surgically intervened. Materials and methodsAn observational and descriptive study was conducted on a series of patients with a cardiac tumour and a suspicion of an intracardiac foreign body over a 7year period (2009-2016). A total of 35 patients were obtained, of which 18 cases were excluded, since of reviewing their clinical notes, the surgical disease did not correspond to an intracardiac mass. The remaining 17 cases had a confirmed histopathology diagnosis of a myxoma. ResultsThe mean age of the patients was 55 and±21 years, with the large majority (82.4%) being female. The most frequent symptom was dyspnoea (52.9%), a clinical history of hypertension (52.9%), and heart failure (52.9%). The echocardiographic features showed that the largest diameter of the tumour was 52 mm (±34). The prevailing location was on the left atrium (64.7%), there was mitral failure in 52.9%). The most common postoperative complications were the shock (17.6%) and stroke (17.6%). Hospital mortality was 5.9%, and the recurrence 6.3%. ConclusionsThe age, gender, diagnosis, morphology / physiology, and operating characteristics, including the mortality and recurrence, were similar to that found in other series. It differed in the proportion of embolisms, and since no patient presented with this symptom at admission, the amount of postoperative complications was less than in other series.
