Key result
A 54-year-old female with pre-existing cardiomyopathy and severe mitral regurgitation developed acute pulmonary edema during her first hyperbaric oxygen therapy session.
Why the study?
Acute pulmonary edema is a rare but severe complication of hyperbaric oxygen therapy, and patients with known cardiovascular problems can experience rapid decompensation.
Does hyperbaric oxygen therapy cause acute pulmonary edema in patients with heart failure with reduced ejection fraction and severe mitral regurgitation?

Does hyperbaric oxygen therapy cause acute pulmonary edema in patients with heart failure with reduced ejection fraction and severe mitral regurgitation?
Hyperbaric oxygen therapy can precipitate acute pulmonary edema in patients with pre-existing cardiomyopathy and reduced ejection fraction, highlighting the need for careful patient selection.
Requires caution for HBOT in low-EF patients with severe MR; hypothesis-generating and should not yet change practice.
Acute pulmonary edema is a rare but severe complication of hyperbaric oxygen therapy. While patients with known cardiovascular problems may be able to withstand this therapy, rapid decompensation can still occur. Here, we present a case of a patient with known low ejection fraction and severe mitral regurgitation who developed acute pulmonary edema during the first hyperbaric treatment for a foot ulcer. This case highlights the importance of identifying patients that are high risk, such as those with moderate-to-severe cardiac disease, and pursuing other treatment options to avoid this complication.

Haris M. Akhter (2023) conducted a case report in Diabetic foot ulcer and heart failure with reduced ejection fraction (n=1). Hyperbaric oxygen therapy was evaluated on Acute pulmonary edema. A 54-year-old female with pre-existing cardiomyopathy and severe mitral regurgitation developed acute pulmonary edema during her first hyperbaric oxygen therapy session.
