This patient is presenting in acute heart failure following a recent sore throat concerning for strep pharyngitis and rheumatic heart disease. In the acute setting, these patients may present with pericarditis, myocarditis, or acute heart failure secondary to valvular regurgitation. Most commonly, the mitral valve is affected, however, the aortic and tricuspid valves are at risk as well. Treatment includes antibiotics, anti-inflammatories, and management of acute heart failure. Steroids and IVIG are controversial and should be discussed depending on the care. Patients are at high risk to develop valvular complications years after their initial presentation. Mitral stenosis is the most common complication seen long-term. Stenosis is caused by chronic fibrosis and scarring of the valve leaflets.
