Abstract

Objectives: Post-cardiotomy cardiogenic shock is an infrequent but important cause of death following cardiac surgery. Extra-corporeal membrane oxygenation offers the opportunity for temporary cardiovascular support and myocardial rest, with a view to recovery. We examine our results with our recently-implemented management algorithm. Methods: We report our series of 15 consecutive patients out of 357 patients [4.2%] who required institution of veno-arterial extra-corporeal membrane oxygenation system support as treatment for Post-cardiotomy cardiogenic shock in the current era [January-2017 to January-2020]. Results: The mean age was 64.3 ± 11.6 years (range: 40–82 years); there were 13 males (86.7%). Duration of veno-arterial extra-corporeal membrane oxygenation support was 6.7 ± 1.9 days. Duration of stay on intensive care unit [ICU] was 18.9 ± 17.1 days. Duration of hospital-stay was 28.3 ± 20.8 days. Survival to discharge and at 2.2 ± 0.9 years was 67%. Conclusions: We have shown clearly that veno-arterial extra-corporeal membrane oxygenation is an important rescue option for patients who develop refractory post-cardiotomy cardiogenic shock, with improved survival of 67% at 2.2 ± 0.9 years in those placed on post-cardiotomy veno-arterial extra corporeal membrane oxygenation support, which is superior to that reported hitherto in literature. We have sought to highlight the successes of post cardiotomy veno-arterial extra corporeal membrane oxygenation support, with improved results, based on careful patient selection, as well as diligent management of these critically-ill patients in the postoperative period, prior to establishment of irreversible end-organ dysfunction. Our strategy has also helped us rationalize and optimize the use of this expensive treatment modality.
