Abstract:
Minimally invasive mitral valve surgery (MIMVS), despite its challenges, is not a rare procedure. However, MIMVS via a right small thoracotomy must be performed using long-shafted surgical instruments and thoracotomy instruments specialized for minimally invasive cardiac surgeries. We have performed 12 cases of MIMVS via right small thoracotomy using the superior trans-septal approach and secured a surgical visual field that easily allows a finger to reach the mitral valve annulus without using special instruments for minimally invasive cardiac surgery. We named this technique the "drawer-case technique." In conclusion, MIMVS via right thoracotomy using the superior trans-septal approach can be performed easily and safely, similar to mitral valve surgery performed via median sternotomy.

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...
