A 71-year-old female, who had been diagnosed with cor triatriatum 30 years before, presented with complains of worsening dyspnea and fatigue. She was diagnosed with a combination of cor triatriatum, mitral valve disease and coronary artery disease. She underwent removal of the left atrial membrane, repair of the mitral valve and coronary artery bypass grafting. This combination of cor triatriatum, mitral valve disease and coronary artery disease is exceedingly rare. She remains well at 3 years’ follow-up.
