Key result
Medical therapy and thyroxine improve pediatric isolated RV cardiomyopathy with autoimmune hypothyroidism.
Why the study?
Isolated right ventricular cardiomyopathy associated with autoimmune hypothyroidism is a rare clinical presentation in adolescents.

May warrant thyroid screening in pediatric isolated RV cardiomyopathy; leaves open whether thyroxine alters progression.
A 13-year-old girl presented with progressive dyspnoea and palpitation, diagnosed on echocardiography as primary right ventricular cardiomyopathy with atrial fibrillation. Her thyroid profile was positive for antithyroid microsomal antibody, and antithyroid peroxidase antibodies were suggestive of autoimmune hypothyroidism. She was managed with furosemide, digoxin, acenocoumarol and thyroxine following which she showed significant improvement. This is a rare case of isolated right ventricular cardiomyopathy and its association with autoimmune hypothyroidism presenting at the age of 13.

Yelve et al. (2015) conducted a case report in Isolated right ventricular cardiomyopathy with autoimmune hypothyroidism (n=1). Furosemide, digoxin, acenocoumarol and thyroxine was evaluated on Clinical improvement. Management with furosemide, digoxin, acenocoumarol, and thyroxine led to significant clinical improvement in a 13-year-old girl with isolated right ventricular cardiomyopathy and autoimmune hypothyroidism.
