Co-Phenotype of Left Ventricular Non-Compaction Cardiomyopathy and Atypical Catecholaminergic Polymorphic Ventricular Tachycardia in Association With R169Q, a Ryanodine Receptor Type 2 Missense Mutation.

Background: Left ventricular non-compaction (LVNC) is a cardiomyopathy characterized by prominent trabeculae and intertrabecular recesses. We present the cases of 3 girls with the sameryanodine receptor type 2(RYR2) mutation who had phenotypes of both catecholaminergic polymorphic ventricular tachycardia (CPVT) and LVNC.

Methods and results: Clinical characteristics and genetic background of the 3 patients were analyzed retrospectively.

Linezolid is a novel and effective treatment for septic pulmonary embolism.

Septic pulmonary embolism (SPE) is an uncommon and severe infectious disease that requires early diagnosis and proper antibiotic therapy. We present the case of a healthy 14-year-old girl with a history of atopic dermatitis, who developed SPE caused by Staphylococcus aureus bacteremia. We initially administered intravenous doripenem and vancomycin.
