Combined transcatheter treatment of severe mitral regurgitation and secundum atrial septal defect in an inoperable patient: a case report
Abstract Background Chronic mitral regurgitation is one of the most common valvular heart diseases and is associated with poor outcome. Although other structural diseases are regularly seen in such patients, concomitant atrial septal defects remain a rarity in the elderly. Case summary We report a case of an 82-year old woman with progressive right-sided heart failure due to mitral regurgitation and an atrial septal defect of secundum type, despite optimal medical therapy. Combined transcatheter mitral valve repair by utilizing a separate transseptal puncture and atrial septal defect closure was performed resulting in amelioration of symptoms. Discussion Procedural planning for simultaneous transcatheter therapies of coupled structural heart disease entities remains complex. Our case illustrates feasibility of percutaneous edge-to-edge mitral valve repair and consecutive closure of a large secundum atrial septal defect. Different options of accessing the left atrium should be discussed on an individual basis, while additional atrial septal defect closure may be beneficial in terms of right ventricular function and symptoms of right heart failure.
