Introduction: Over the past decades minimally invasive cardiac surgery has grown in popularity. This growth has been driven by desire to translate many observed benefits like less pain, better cosmesis, less surgical trauma as compared to traditional cardiac surgery. This study’s objective is to evaluate safety and effectiveness of minimally invasive cardiac surgery in a teaching hospital with respect to learning curve, quality of life, and mid term outcomes.

Material and methods: In this study 50 patients diagnosed having mitral or aortic valve disease requiring replacement of the valve and atrial septal defect requiring surgical closure operated between 1/08/2011 to 31/12/2018 are included.

Results: 38 patients were operated by right thoracotomy while 12 patients were operated by mini sternotomy. In our institution femoral platform is utilized for establishing cardio pulmonary bypass. Cardiopulmonary bypass time for mitral valve surgery was 116+–18.7, min, for aortic valve surgery was 138+–19.6.8 min and for ASD closure
was 95+–15.4.4 min. no significant early or mid term complication including re exploration, long duration of surgery or other systemic complications pertaining to respiratory, pulmonary or nervous systempertaining to surgery. All patients showed improvement in NYHA class from their pre operative period in follow up stage.

Conclusion: Minimally invasive cardiac surgery is the upcoming boom and it can be safely performed with the
available newer cannulae, anesthesia techniques and surgical instruments.
