A child with a history of strep throat presents with fever, shortness of breath, abdominal pain, and a very painful and swollen shoulder joint. Based on this history and presentation, what medical condition should be suspected?

A. Kawasaki disease typically presents with fever, conjunctivitis, rash, swollen hands/feet, and lymphadenopathy, not following strep throat or with joint pain as a primary feature. B. Rheumatic heart disease is a complication of rheumatic fever, which can follow an untreated or inadequately treated streptococcal throat infection. The child’s symptoms—fever, shortness of breath (carditis), abdominal pain, and painful swollen joint (arthritis)—are classic signs of rheumatic fever, which can lead to long-term cardiac damage. C. Coarctation of the aorta is a congenital condition involving narrowing of the aorta and typically presents with differential blood pressure between extremities, not joint swelling or post-streptococcal symptoms. D. Dextro-transposition of the great arteries is a cyanotic congenital heart defect that presents in newborns, not older children with post-infectious symptoms.
