Two sentences contain errors at the bottom of page 982 in the Clinical Expert Series article by Martin in the November 2019 issue.1 The correct sentences are: “Venovenous ECMO is similar to venoarterial ECMO; however, the oxygenated blood is returned by the patient's venous circulation and does not offer circulatory support, only pulmonary. Venovenous ECMO has been used in patients with right heart failure related to pulmonary embolism and has also been shown to be beneficial in offloading the right ventricle in situations with significant right to left intracardiac shunts.36

A Letter to the Editor regarding this correction appears in this issue on page 977.
