This case report details the management of a 79-year-old man who developed massive postoperative pneumothorax following redo coronary artery bypass grafting due to severe lung adhesions. We successfully treated the patient using veno-venous extracorporeal membrane oxygenation without femoral cannulation, allowing for early rehabilitation initiation. Veno-venous extracorporeal membrane oxygenation is a reasonable option for cases of severe respiratory failure due to pneumothorax with lung destruction caused by re-sternotomy during re-do cardiac surgery.

Acute coronary syndrome with cardiogenic shock is a life-threatening condition, but with planned staged treatment combined with coronary revascularization and mechanical circulatory supports its management is increasingly possible. Here, we present our successful life-saving case. A 76-year-old male patient was diagnosed with ST-elevation myocardial infarction with cardiogenic shock due to severe stenosis of the left main coronary artery based on the severe triple vessel disease. We initially introduced Impella CP and performed a percutaneous coronary intervention without stenting on the patient. We maintained hemodynamics with Impella CP and performed coronary artery bypass grafting after a week. Intraoperatively, Impella CP was left to function as a left ventricular vent. The patient required upgrading to Impella 5.5 plus veno-arterial extracorporeal membrane oxygenation postoperatively, but his condition gradually improved, all mechanical circulatory supports could be weaned off, and he eventually survived.
