Abstract Lutembacher syndrome, a rare combination of atrial septal defect (ASD) and mitral stenosis (MS), presents unique diagnostic and management challenges. We present an 18-year-old female with exertional dyspnea, volume-overload palpitations, and paroxysmal atrial tachyarrhythmia. Examination revealed the signs of increased pulmonary flow, a mid-diastolic murmur, and an ejection systolic murmur at the pulmonary area. Imaging demonstrated a nonrestrictive ostium secundum ASD with severe MS and pulmonary hypertension. The differential diagnosis, pathophysiological interplay, and management strategies, including considerations for percutaneous versus surgical correction, are discussed in detail, highlighting the teaching value of this classical lesion.
