What you do not know, you do not recognize…and you do not improve future patient care…particularly in extracorporeal life support (ECLS) patients

In the article that appeared on Page S1930-1934, Supplement 15 (September 2019) Issue of the Journal of Thoracic Disease (JTD) (1), there is a mistake on the quoted statement. Here, we sincerely apologize for the mistakes.

The title of this editorial comes from a statement (“Wat je kent niet, herken je niet”) by Prof. Hein J. J. Wellens, former Head of the Cardiology Department at the Maastricht University Medical Centre, The Netherlands.

Therefore, the correct sentence should have read as follows:

The title of this editorial comes from a statement (“Wat je niet kent, herken je niet”) by Prof. Hein J. J. Wellens, former Head of the Cardiology Department at the Maastricht University Medical Centre, The Netherlands.

The authors regret the error.
