However at the middle measure-ment (week-of-surgery) women did not have a drop indepressive symptom levels like men did (p = 0.01), andinstead maintained similar depression levels as at base-line. There was a trend towards significance for the samepattern in anxiety symptoms (p = 0.07).Conclusion: There may be gender differences in psycho-emotional symptoms at the week of scheduled CABGsurgery.

159Long-term Results Following Mitral Valve Repair forDegenerative Mitral Regurgitation

Michael Gardner ∗, Kenneth Hossack

St Andrews Hospital, Brisbane, Australia

Mitral valve repair is now the accepted standard for severedegenerative mitral regurgitation.From 1991 to June 2007, 570 patients underwent mitralrepair. Age 19–89 years (average 65). 391 males and 179females. NYHA Class: I 85, II 226, III 177, and IV 72.Pre-op TTE: MR Grades 3–4 in 526 (96%), EF 30–85 (65%),LVESD 20–69 (36).Mechanism MR: Post leaflet 369, bileaflet 135, anteriorlTtprrcAm1PTrSrEbL(

Introduction: Port–Access surgery, which involvesapproaching the heart through ports of small size, hasbeen one of the most original and controversial methodsof minimally invasive surgery in recent times. It is aprospective study of cases underwent MIS for one oranother reasons.Materials and methods: Inclusion criteria’s are all isolatedmitral valve disease, intracavitory tumors, redo surgery,abRopPdlarnowteCtmc

Echocardiography revealed EF: 58.12 ± 4.14%;A press: 35 ± 4.45 mmHg; LA area: 28.50 ± 3.56 cm2; LVEDiam: 58 ± 2.53 mm; LVES diam: 38 ± 3.21 mm. Mean

In hospital morbidity includes, reexploration (4),ne stroke and one permanent pacemaker insertion. Noound infection noted with very low incidence of blood

ransfusion. Follow-up includes 23 months with no reop-rations.onclusion: Early results are proving MIS as a promising

echnique. With the time its application will expand, fromitral valve surgery to other pathological conditions like
