Infective endocarditis in an adult male patient with tetralogy of Fallot physiology secondary to double outlet right ventricle presenting with stroke: a complex presentation with multiorgan dysfunction—a case report

This case is remarkable because the patient survived up into adulthood with double outlet right ventricle and tetralogy of Fallot physiology without prior corrective surgery, which is a rare occurrence. The embolic stroke, likely resulting from a septic embolus, and the presence of Fanconi anemia further complicated the clinical scenario. Despite aggressive treatment, the patient's progression to refractory sepsis and disseminated intravascular coagulation ultimately resulted in cardiac arrest. This case underscores the importance of early recognition, multidisciplinary collaboration, and tailored therapeutic strategies in managing complex congenital heart diseases with infective endocarditis and other comorbidities.
