Abstract
BACKGROUND
Cardiac myxomas are the most frequent primary benign intracardiac tumors. We reviewed our 27-year experience to evaluate factors associated with an embolism in patients with cardiac myxomas and their long-term outcomes.
METHODS
A retrospective review identified 99 patients with cardiac myxomas between 1985 and 2012. Tumors were divided into two groups based on their gross external features. Tumors with a smooth regular border and a solid consistency were classified as solid; papillary myxomas were characterized by an irregular and gelatinous exterior with friable, soft consistency. The patients were classified into embolic and non-embolic groups to focus on embolic events.
RESULTS
Mean age at surgery was 49.8 ± 16 years. There were 92 left atrial myxomas (92.9%). Embolization was observed in 25 patients (25.3%) before surgery. Three variables were associated with an embolic event, small tumor size (odds ratio [OR] = 4.36 P = 0.037 confidence interval [CI] 95% 0.534-0.980), atrial fibrillation (OR = 10.119 P = 0.001 CI 95% 0.021-0.397), and papillary-type pathology (OR = 11.544 P = 0.001 CI 95% 0.033-0.399). Tumor pathology or the presence of embolization prior to surgery had no effect on operative mortality or long-term survival.
CONCLUSIONS
Embolization of cardiac myxomas is more likely to occur in papillary-type tumors, that are smaller in size and in patients presenting with preoperative atrial fibrillation. However, the presence of embolization at the time of surgery does not increase operative morbidity or mortality or affect long-term survival.
