Minimally Invasive Cardiac Surgery Overview Traditional approach to heart valve surgery has been through a median sternotomy. The breast bone is sawed in half in order to approach the heart. Figure 1. Raymond Lee, MD Mark Mostovych, MD Jacksonville, Florida USA Minimally invasive techniques are used for aortic and mitral valve surgery. Our minimally invasive approach involves approaching the heart between the ribs and leaves the sternum intact. Figure 2. For minimally invasive surgery, the incision is about 3 to 4 inches instead of the incision required for traditional surgery that is 6 to 8 inches long. MICS Potential Benefits of Minimally Invasive Surgery A smaller incision/scar Less bleeding/transfusion Decreased need for rehab Figure 1. Figure 2. Improved pulmonary function Decreased length of stay 1,2 Decreased recovery time: the average recovery time after minimally invasive surgery is 2 to 4 weeks, while the average recovery time after traditional heart surgery is 6 to 8 weeks Increased mitral valve repair due to optimal visualization and exposure The views and teaching techniques expressed are those of medical professionals and not necessarily the views of Sorin Group USA, Inc. Technique Overview Less pain/pain meds Case: 65 yr. old male with severe AS (0.7cm2, 65mm Hg gradient). Technical Aspects • Patient supine with arms tucked at side • Double lumen endotracheal tube, radial arterial line to avoid groin lines, defib pads since it is difficult to defibrillate via incision • ECHO guidance for retrograde cardioplegia catheter, surgeon places retrograde catheter • Avoid any lines in right subclavian or femoral areas Aortic Valve Replacement • Incision in second interspace (between second and third ribs) • Divide RIMA, shingle third rib close to sternal edge and laterally • Edwards soft tissue retractor and Estech™ retractor • Resect thymic fat pad, avoid phrenic nerve • Pericardial retraction sutures using percutenous needle for lateral pericardial sutures • Mitroflow® Aortic Pericardial Heart Valve • Cannulation -- EasyFlow™ Aortic Cannula (#103-300) -- Edwards Fem-Flex II™ femoral venous cannulae with connector, VFEM022 (Size: 22 Fr.) or VFEM024 (Size: 24 Fr.) based on patient size -- CardioVasive™ Chitwood Transthoracic Aortic Cross Clamp, antegrade and retrograde cardioplegia Case: 42 yr. old female with known mitral valve prolapse who developed acute SOB and decreased exercise tolerance. Mitral Valve Surgery • Incision in third interspace shingle third or fourth rib based on body habitus • Alternatively, may use inframammary incision • Edwards soft tissue retractor and Estech retractor • Resect thymic fat pad, avoid phrenic nerve • Pericardial retraction sutures using percutenous needle for lateral pericardial sutures • MEMO 3D™ Semi-rigid Annuloplasty Ring • Cannulation -- Percutaneous femoral vein 2 stage cannula to drain SVC and IVC effectively with the Bio-Medicus® Multi-Stage Cannulae, 96880-021 (Size: 21 Fr.) or 96880-025 (Size: 25 Fr.) MICS -- EasyFlow Aortic Cannula (#103-300) based on patient size antegrade and retrograde cardioplegia How Do I Begin?
