Late Manifestation of Congenital Heart Disease: Right-side Infective Endocarditis and the Mystery of the Unseen Ventricular Septal Defect: Case Report

Abstract

Infective endocarditis (IE) is a severe complication in patients with congenital heart disease. However, CHD-associated mortality has decreased to 10% because of improvements in the diagnosis of infective endocarditis, antibiotic therapy, cardiac surgery, and interventional procedures. Herein, we aimed to illustrate a case of right-sided infective endocarditis associated with an unknown ventricular septal defect, complicated by septic pulmonary emboli as a rare form of delayed presentation of congenital heart disease. The significant occurrence of infective endocarditis prompts the need for additional investigations into the current utilization, necessity, and effectiveness of antibiotic prophylaxis in patients with congenital heart disease (CHD).
