that MICS for redo cases is safer than median sternotomy . Opting for open conversion to ensure adequate cardioplegia dosing carries the risk of SVG damage , which could be catastrophic . Recent meta-analyses have highlighted the advantages of MICS over median sternotomy for redo cases , deeming it effective even for high-risk patients [ 1 ].
Therefore , we believe that our MICS approach to circumvent open conversion was optimal for this patient . Previously , we reported a complex case managed under systemic hyperkalemia [ 3 ]. In this instance , despite the addition of circulatory arrest , no major complications were observed , and the postoperative course was uneventful , leading to the patient ’ s discharge .
We advocate for the utility of this strategy in managing cardioplegia-related issues in complex cases . Nonetheless , there is limited literature on right thoracotomy under systemic hyperkalemia CPB combined with circulatory arrest , indicating the need for further investigation into this technique .
