Cardiac resynchronization therapy (CRT) is used as an adjunctive therapy in adults with advanced heart failure but remains less commonly applied in pediatric patients. Further, CRT is traditionally conducted via biventricular transvenous pacing from the right ventricle and coronary sinus to activate the left ventricle and improve electromechanical synchrony; however, triventricular pacing, in which a third ventricular lead is utilized to activate an additional ventricular location, has been shown to be a feasible therapeutic alternative to typical CRT in patients with advanced heart failure or nonresponders. Limited adult studies involving triventricular pacing have been performed to date but no pediatric data are available. Thus, we present the case of a 12-month-old patient with congenital complete heart block and subsequent pacemaker-induced cardiomyopathy in whom triventricular epicardial pacing was applied in an effort to increase the available knowledge.
RESUMO
Chondrosarcoma is a malignant bone tumour common in adults, third to myeloma and osteosarcoma, but is exceptionally rare in children. Here we discuss a 9-year-old girl presenting with occlusive right pulmonary artery neoplastic embolus, resulting from a primary right proximal humerus chondrosarcoma. To the best of our knowledge, this the first pediatric and only second overall case reported in the United States of a neoplastic pulmonary embolus resulting from a primary chondrosarcoma.

Primary osteosarcoma accounts for 3% of all childhood cancer. It commonly occurs during the adolescent growth spurt and is more common in boys than girls and in African Americans than white people. The 5-year survival is approximately 79%. Cardiac metastasis of osteosarcoma is exceedingly rare; we present an unusual case in a 22-year-old man with significant intracardiac tumor burden. Additionally, we review the current pediatric cardiac tumor literature.
