Abstract
A minimally invasive approach for surgery on portions of the heart and great vessels located between a point approximately three centimeters above supra annular ridge and the mid ventricular cavity. A parasternal incision is made extending across a predetermined number of costal cartilage, e.g., a right parasternal incision extending from the lower edge of the second costal cartilage to the superior edge of the fifth costal cartilage. One or more costal cartilages, e.g., the third and fourth, are then excised to provide access to the portion of the heart or great vessels of interest, and a desired procedure completed. The minimally invasive approach enables repair or replacement of the mitral or aortic valve.
Claims24
A method of performing minimally invasive cardiac valve repair or replacement surgery on a patient comprising the steps of:
- preparing the patient for surgery;
- making an incision in the chest of the patient;
- said incision being approximately 10 cm in length;
- said incision being made within a region on the chest that enables direct access to a location in the heart approximately 3 cm above the supra annular ridge and in the mid-ventricular cavity;
- establishing cardiopulmonary bypass using at least one blood conduit placed within the region;
- exposing a surgical field within said area approximately 3 cm above the supra annular ridge and in the mid-ventricular cavity;
- and,
- performing a valve repair or replacement procedure within the surgical field.
A method of performing minimally invasive cardiac valve repair or replacement surgery on a patient comprising the steps of:
- preparing the patient for surgery;
- making an incision in the chest of the patient;
- said incision being approximately 10 cm in length;
- said incision being confined to a substantially rectangular area on the chest;
- said rectangular area extending approximately two inches on either side of the sternum and from no higher than the first intercostal space at the top to the sixth intercostal space at the bottom;
- establishing cardiopulmonary bypass using at least one blood conduit placed within the rectangular area;
- exposing a surgical field below said incision;
- and
- performing a valve repair or replacement procedure within the surgical field.
A method of performing minimally invasive cardiac valve repair or replacement surgery on a patient comprising the steps of:
- preparing the patient for surgery;
- making a straight incision of approximately 10 cm in length in the chest of the patient;
- establishing cardiopulmonary bypass using at least one blood conduit placed in a region near said incision;
- incising and retracting tissue in the area beneath the incision so as to expose a portion of the heart where surgery is required;
- and
- performing a valve repair or replacement procedure on the exposed portion of the heart including establishing cardiopulmonary bypass.
