Key result
Minimally invasive cardiac surgery speeds recovery but carries unique risks of pulmonary edema and vascular injury.
Why the study?
Minimally invasive cardiac surgery (MICS) via intercostal thoracotomy has increased, but specific complications and pitfalls unique to MICS require thorough understanding and prevention.
While MICS offers advantages such as faster recovery and superior cosmesis, surgeons must be highly aware of and actively prevent unique complications like unilateral pulmonary edema and vascular injuries, especially during the learning curve.

Alerts surgeons to MICS pitfalls on adoption; leaves open need for prospective trials quantifying net benefit.
肋間開胸による低侵襲心臓手術 (MICS: Minimally InvasiveCardiac Surgery) が近年増加している．2018～2019年のJCVSDのデータによれば，僧帽弁手術の42.6%がMICSで実施されていた．MICSは整容性に優れるだけでなく，胸骨を切開しないため，退院後の運動制限がなく社会復帰が早いなど，多くの利点があるが，MICS特有の合併症など注意すべき点も多い．限られた術野内での手術操作に関する問題と，大腿動静脈アクセスによる体外循環に関連する問題があり，ラーニングカーブにおいて合併症が多く発生する傾向がある．MICSを導入する際には，これらのピットフォールを十分に理解し，予防することが何よりも重要である．

Taichi Sakaguchi (2023) conducted a review in Heart valve disease requiring surgery. Minimally Invasive Cardiac Surgery (MICS) vs. Standard sternotomy was evaluated. Minimally invasive cardiac surgery provides benefits like faster recovery but is associated with specific pitfalls including unilateral pulmonary edema, bleeding, and vascular injury that require careful prevention.
