We describe a novel technique of left atrial volume reduction in a patient presenting with severe dyspnea from severe mitral insufficiency, giant left atrium, and compressive symptoms of dysphagia and dysphonia. Resection involved circumferential excision of the left atrium anterior to the pulmonary venous vestibule and posterior to the mitral valve and fossa ovalis, including the left atrial appendage. A chordal-sparing bioprosthetic mitral valve replacement, tricuspid valve annuloplasty, and coronary bypass were also performed. Significant reduction of left atrial volume by 50% was achieved and clinical resolution of compressive symptoms was seen at 6-month follow-up.
