Abstract:
In minimally invasive mitral valve surgery, exposure in the medial left atrium is occasionally poor. A flexible exposure system for minimally invasive surgery was constructed using a tin plate (99.9% pure tin). The tin plate is very flexible and embossed to prevent slippage, and it is attached to a left atrial retractor. The folded tin plate is inserted into the left atrium via a minithoracotomy, and the plate is easily expanded using forceps, as needed. The tin plate pushes the medial atrial wall outward, which provides an excellent view of the entire mitral valve.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
