BACKGROUND: Minimally invasive double valve surgery is relatively lesser known in this part of the globe.. Here we are reporting a case of double valve surgery using minimally invasive approach.


METHODS: A 31yrs old female with post CMV(12yrs back), post MTP(22-days back) status with Hb%=7.3gm was admitted for DVR Gradient across aortic valve=55mm Hg with grade II -AR and MVA=0.8 cm. She had past H/O MTP twice due to her cardiac condition. . A 4 inch size skin incision is made. Sternum is cut with oscillating saw up to the 3rd ICS. Adhesion due to previous surgery were removed, adhesion from Aorta,,PA,&RA are also removed very carefully. Cannulation was carried .through femoral artery and two stage venous cannula in to RA Venous cannula was delivered out from the future drains tube site just below xyphoid. 1st cardioplegia was delivered antigrade in to the aortic root, rest were delivered directly in to the ostea . .Fusion between RCC & NCC up to the mid point was released, partial fusion between RCC & LCC also released. Annulus found to be dilated which was tackle later on after mitral valve correction. Mitral valve was approach through aortic aortic opening, LA was also incise. Complete MV was not seen even through this incision due to previous CMV. Through aortic opening and LA MV and its subvalver apparatus were inspected and decided to go for MV commisurotomy and release of chordal and papillary fusion.Valve is check for any leakage . Now aortic annular dilatation is dealt with reduction annuloplasty using 4-0 teflon pledgated prolien suture.t.
Immediate and late post operative period was smooth and uneventful. Ventilator was removed 3hrs after surgery.On day one blood loss was 120ML.Two units of blood was required post operatively.PCM was given as pain killer.Pnt was shifted to the ward on2nd POD ,and was discharged on 4th POD

REASULT: DVR can be carried out without much of the difficulty using minimally invasive approach. .In this particular patient post operative blood loss was significantly low. Requirement of post operative analgesia is also less. It gives patient a sense of INTACT CHEST.

CONCLUSION: Minimally invasive double valve surgery can be carried out without much difficulty with numerous advantages.
