Surgery for primary cardiac tumors in children: early and late results in a multicenter European Congenital Heart Surgeons Association study


Abstract

BACKGROUND: To evaluate indications and results of surgery for primary cardiac tumors in children.
METHODS AND RESULTS: Eighty-nine patients aged ≤18 years undergoing surgery for cardiac tumor between 1990 and 2005 from 16 centers were included retrospectively (M/F=41/48; median age 4.3 months, range 1 day to 18 years). Sixty-three patients (68.5%) presented with symptoms. Surgery consisted of complete resection in 62 (69.7%) patients, partial resection in 21 (23.6%), and cardiac transplant in 4 (4.5%). Most frequent histotypes (93.2%) were benign (rhabdomyoma, myxoma, teratoma, fibroma, and hemangioma). Postoperative complications occurred in 29.9%. Early and late mortality were 4.5% each (mean follow-up, 6.3±4.4 years); major adverse events occurred in 28.2% of the patients; 90.7% of patients are in New York Heart Association class I. There were no statistically significant differences in survival, postoperative complications, or adverse events after complete and partial resection in benign tumors other than myxomas. Cardiac transplant was associated significantly with higher mortality rate (P=0.006). Overall mortality was associated to malignancy (P=0.0008), and adverse events during follow-up (P=0.005).
CONCLUSIONS: Surgery for primary cardiac tumors in children has good early and long-term outcomes, with low recurrence rate. Rhabdomyomas are the most frequent surgical histotypes. Malignant tumors negatively affect early and late survival. Heart transplant is indicated when conservative surgery is not feasible. Lack of recurrence after partial resection of benign cardiac tumors indicates that a less risky tumor debulking is effective for a subset of histotypes such as rhabdomyomas and fibromas.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
