Is prosthetic anuloplasty necessary for durable mitral valve repair?
Mitral valve repair without a prosthetic anuloplasty was associated with accelerated return of mitral regurgitation, although risk-adjusted survival was similar. This finding has important implications for durability of percutaneous mitral repair techniques that do not address both leaflets and anulus.
Dyspnea is a complex perception, and in patients with fILD, O2 may lessen, but does not resolve, it. Further research is needed to clarify why fILD patients who use O2 perceive greater levels of dyspnea with activity than O2 non-users.
