Key result
Superior trans-septal approach for minimally invasive mitral surgery shows safety and feasibility without specialized instruments.
Why the study?
Minimally invasive mitral valve surgery via right small thoracotomy traditionally requires specialized long-shafted and thoracotomy instruments, posing procedural challenges.
Does the superior trans-septal approach improve surgical exposure and feasibility in minimally invasive mitral valve surgery via right small thoracotomy?

The superior trans-septal approach for minimally invasive mitral valve surgery via right small thoracotomy provides excellent surgical exposure without the need for specialized minimally invasive instruments.
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.

Yamazaki et al. (2019) conducted a case report in Mitral valve disease requiring surgery (n=12). Superior trans-septal approach (drawer-case technique) was evaluated on Feasibility and safety. The superior trans-septal approach for minimally invasive mitral valve surgery via right small thoracotomy was performed easily and safely in 12 cases without requiring specialized instruments.
