Barlow's disease presents the most severe form of degenerative mitral valve disease as it normally affects various valvular structures and segments. We discuss the technical aspects of mitral valve repair in this setting. Furthermore, the concept of "functional prolapse" of the mitral valve is discussed as well as recommendations on when to proceed with surgical correction of anterior leaflet prolapse.

Introduction: Mitral valve prolapse (MVP) is a common valve pathology with a spectrum of disease from isolated prolapse to myxomatous, multi-scallop Barlow's disease. The main complications relate to progression of mitral regurgitation, endocarditis, sudden death, and stroke. The timing of intervention in patients with asymptomatic severe mitral regurgitation is controversial. Areas covered: This article reviews the pathophysiology, genetics, clinical features, diagnostic imaging, complications, long-term outcomes, and indications for intervention in MVP. Expert commentary: Several key dilemmas in the management of MVP remain. Factors which influence progression of mitral regurgitation are unclear and therefore, we have no therapeutic targets to prevent progression. Evidence-based methods to reduce the risk of sudden death, stroke, and endocarditis have not been identified. In symptomatic patients with severe mitral regurgitation valve surgery is recommended. In asymptomatic patients, careful risk stratification incorporating markers of left ventricular dysfunction, atrial fibrillation, pulmonary hypertension, and valve reparability is required to identify the optimal timing of intervention.

Barlow syndrome is a form of degenerative mitral valve (MV) disease found in a subset of patients with bileaflet prolapse. The hallmark of Barlow's disease includes excessive and billowing leaflet tissue caused by myxomatous tissue proliferation, elongated chordae, and pronounced annular dilatation. Surgical repair of patients with Barlow's disease is challenging due to the extent of the leaflet and annular abnormalities. Several techniques have been described to repair Barlow's MV including currently popular "non-resectional" approaches. Repair with neochordae has been associated with excellent results and includes the advantage of preserved leaflet mobility and a large surface of coaptation. We describe a simple approach to the use of neochordae to repair bileaflet prolapse in patients with Barlow syndrome and avoid systolic anterior motion.
