We present the case of a symptomatic young woman with mitral stenosis and regurgitation due to a congenital mitral arcade. Multimodality imaging with echocardiography and computed tomography were used for diagnosis and surgical planning. The patient underwent successful bioprosthetic valve replacement. (Level of Difficulty: Intermediate.)

The patient's medical history was significant for childhood asthma. There was no history of tonsilitis.

She had antibodies consistent with a recent infection of coronavirus disease-2019 (COVID-19) and recalled

To recognize the clinical presentation and differential diagnosis of mitral stenosis to diagnose congenital mitral arcade. To use multimodality imaging in characterizing the mitral valve and submitral apparatus to guide treatment of mitral valve disease. Mitral Arcade With Anomalous Papillary Muscles 1305 results of the lung were notable for diffuse panlobular interstitial fibrosis with intra-alveolar hemosiderinladen macrophages (Figure 9 ). There was no evidence of vaping-induced lung injury, organizing pneumonia, or bronchiolitis.

The patient returned for outpatient follow-up 2 weeks postoperatively and reported improving symptoms.
