Advantages and disadvantages of aortic valve surgery approaches.
Full Sternotomy | Hemi-Sternotomy | Right Anterior Minithoracotomy | |
---|---|---|---|
Access | Unfettered view of whole mediastinum and whole heart | Good access to aortic root, limited to whole heart | Most challenging view |
Sternal disruption | Whole sternum | To 2nd–4th intercostal spaces unilaterally or bilaterally | None, although costal cartilages are sometimes divided (may include right mammary artery ligation) |
Cannulation | Full central | Variable—from full central to aortic arterial only | Typically requires peripheral cannulation |
Instruments | Standard cardiac | Variable—can be standard or long-handled | Typically requires long-handled |
Technical difficulty | Baseline | Learning curve easily traversed, including for trainee surgeons | Accepted to be technically challenging |
Adjuncts Required | None | Variable—possible with standard equipment. Facilitated by rapid deployment valves, suture placement devices, and knot-tying devices | Facilitated by rapid deployment valves, suture placement devices, and knot-tying devices; Light source advantageous; Single lung ventilation. |
Benefits (from most recent meta-analyses) * | Reduced intensive care and hospital length of stay; Reduced ventilation time |
Reduced hospital length of stay; Reduced ventilation time; Lower stroke rate; Lower pacemaker rate |
|
Risks * | Increased operative time; Increased costs |
Increased operative time; Increased costs (including vs. ministernotomy); Lung herniation |
* compared to median sternotomy unless stated otherwise.
