Abstract
Background: Port access approach (PA) in mitral valve surgery is a flourishing favourite surgical technique in comparison to the Median Sternotomy approach (MS). PA was pioneered to reduce transfusion requirements, improve cosmetics, reduce costs and length of hospitalisation, improve postoperative morbidity and pain along with ventillatory demands. This study was conducted to investigate the various clinical outcomes in evaluating the advantages and benefits of minimally invasive surgery. Patients and Methods: The early results after mitral valve repair (MVr) performed by single centre (Blackpool Victoria hospital) were collected prospectively from a sample size of 100 consecutive patients between August 2010 and June 2012. PA MVr group involved equal number of patients as the MS MVr group (50 patients each). The patients were followed up for 6 months post operatively. Results: The mean age was 61.78 +/- 11.97 years for the PA group versus 63.02 +/- 11.69 years in the MS group (P = 0.601). 47% of sample size were categorised as New York Heart Association (NYHA) class III and IV with 48% belonged to the PA group with 20% have ejection fraction of less than 50%.The mean grade of preoperative Mitral Regurgitation (MR) in the PA group was 52% with 3+ MR and 48% with 4+MR
