Chordae Tendinea Rupture and Pulmonary Valve Vegetation in Pediatric Endocarditis: A Rare Condition

Abstract

Infective endocarditis (IE) is a severe yet rare condition in pediatric patients, often presenting with nonspecific symptoms, which can complicate diagnosis. Chordae tendinea rupture and pulmonary valve involvement are uncommon complications of IE, warranting timely recognition and management to prevent further morbidity and mortality. We present a case of a nine-year-old male child with a rare presentation of endocarditis complicated by chordae tendinea rupture and pulmonary valve vegetation. The child presented with a one-month history of abdominal pain, dyspnea, edema, and cough. Initial investigations revealed severe mitral regurgitation (MR) and tricuspid regurgitation (TR), chordae tendinea rupture, and vegetation on the pulmonary valve. Despite antibiotic therapy, the child's symptoms persisted, necessitating transfer to a tertiary care center for advanced cardiac management. Chordae tendinea rupture is a rare but critical complication of endocarditis, leading to significant valvular dysfunction. Pulmonary valve involvement in endocarditis is relatively uncommon, with most cases involving the mitral and aortic valves. Identifying vegetation on the pulmonary valve underscores the importance of comprehensive echocardiographic evaluation in patients with suspected endocarditis, regardless of valve involvement. Management of pediatric endocarditis involves a multidisciplinary approach, including antibiotic therapy and potential surgical intervention. Despite antibiotic therapy, the child continued to experience fever spikes in this case, indicating a potential need for surgical intervention. In conclusion, this case report highlights the rare presentation of chordae tendinea rupture and pulmonary valve vegetation in pediatric endocarditis. Timely diagnosis and appropriate management, including antibiotic therapy and potential surgical intervention, are essential for optimizing outcomes in affected children.
