Triple-orifice valve repair in severe Barlow disease with multiple-jet mitral regurgitation: Report of mid-term experience

摘要: Abstract Objectives Barlow disease represents a surgical challenge for mitral valve repair (MR) in the presence of insufficiency (MI) with multiple regurgitant jets. We hereby present our mid-term experience using modified edge-to-edge technique to address this peculiar MI. Methods From March 2003 till December 2010, 25 consecutive patients (mean age 54±7years, 14 males) affected by severe jets were submitted MR. Preoperative transesophageal echo (TEE) all cases showed at least 2 jets, involving one or both leaflets more than segment. In patients, triple orifice (TOV) annuloplasty was performed. Intra-operative TEE and postoperative transthoracic echocardiography (TTE) carried out evaluate results TOV repair. Results There no in-hospital death late (non-cardiac related). At intra-operative TEE, three orifices mean total area 2.9±0.1cm (range 2.5–3.3cm ) residual regurgitation (2 trivial MI) sign stenosis transvalvular gradient 4.6±1.5mmHg). follow up 38±22months), TTE favourable MR recurrence significant MI (6 1 mild MI). Stress performed 5 showing persistent effective function peak exercise). All NYHA functional class improvement. Conclusions This report indicates that is correcting complex valves Further studies are required confirm long-term applicability durability numerous clinical cases.
