Key result
An additional ECMO pump without an oxygenator effectively provided transseptal left atrial decompression by controlling the blood flow rate of the transseptal LA catheter.
Why the study?
Transseptal left atrial decompression with venoarterial ECMO is not always effective for severe left ventricular dysfunction.
Case Report (n=1)
An additional ECMO pump without an oxygenator can effectively provide transseptal left atrial decompression in patients with severe left ventricular dysfunction on venoarterial ECMO.
May offer a feasible LA decompression option on VA-ECMO; leaves open safety and efficacy questions for prospective evaluation.
A 63-year-old man developed chest pain and dyspnea. Venoarterial-venous extracorporeal membrane oxygenation (ECMO) was applied to the patient due to failing heart after percutaneous coronary intervention. We used an additional ECMO pump without an oxygenator for transseptal left atrial (LA) decompression and performed a heart transplant. Transseptal LA decompression with venoarterial ECMO is not always effective for severe left ventricular dysfunction. Here, we report a case of the effective use of additional ECMO pump without an oxygenator for transseptal LA decompression through controlling the blood flow rate of the transseptal LA catheter.

Yang et al. (2023) conducted a case report in Failing heart after percutaneous coronary intervention (n=1). Additional ECMO pump without an oxygenator was evaluated on Effective transseptal left atrial decompression and successful heart transplant. An additional ECMO pump without an oxygenator effectively provided transseptal left atrial decompression by controlling the blood flow rate of the transseptal LA catheter.
