[Aortico-left ventricular tunnel associated with pulmonary valve stenosis]. / Túnel aorta-ventrículo izquierdo asociado con estenosis valvular pulmonar.

Aortico-left ventricular tunnel is an unusual cardiac anomaly. The main clinical feature is early, severe aortic regurgitation, and surgical management is mandatory. Exceptionally this defect is associated with pulmonary valve stenosis. A case of a newborn with aortico-left ventricular tunnel plus pulmonary valve stenosis is reported. Initially she underwent percutaneous pulmonary valvuloplasty during diagnostic cardiac catheterization and with surgical closure of the tunnel later.

[Intracardiac mycetoma induced by central catheterization]. / Micetoma intracardíaco inducido por un catéter de vía central.

We report a case of an infective endocarditis presented as a right atrial mass which pathological study showed a big vegetation of candida albicans (mycetoma). We think its presence was related to a great central vein catheterization during the neonatal period. The clinical feature was completed with pulmonary fungal embolism and later tricuspid valve afectation. With this work we wish to remark the necessary careful management of patients with central vein catheters to avoid this severe complication. We review the pharmacological and surgical treatment of this uncommon entity.
