A minimally invasive approach lor surgery on portions ol the heart and great vessels. A parasternal incision is made extending across a predetermined number ol costal cartilages, e.g., a right parasternal incision extending from the lower edge ol the second costal cartilage to the superior edge ol the filth costal cartilage. One or more costal cartilages, e.g., the third and fourth, are then excised to provide access to the portion ol the heart or great vessels ol interest, for example between a point approximately three centimeters above supra annular ridge and the mid ventricular cavity, and a desired procedure completed. A minimally invasive procedure for repair or replacement ol the aortic valve is disclosed that includes making a transverse incision ol about 10 cm in length over the second or third intercostal space in the thorax ol the patient, dividing the sternum transversely following the incision, retracting the transversely divided sternum, exposing the ascending aorta, and incising the ascending aorta to provide access to an area adjacent the aortic valve.
