Why the study?
What is the prevalence of asymmetric pulmonary edema predominantly involving the right upper lobe in patients with severe mitral regurgitation?
What is the prevalence of asymmetric pulmonary edema predominantly involving the right upper lobe in patients with severe mitral regurgitation?
Asymmetric pulmonary edema predominantly involving the right upper lobe occurs in 9% of patients with severe mitral regurgitation, highlighting the need to consider this in the differential diagnosis of right upper lobe opacities.
No takes yet. Share an insight, caveat, or question.
Supports considering mitral regurgitation in right upper lobe opacity differentials; extends edema pattern descriptions but leaves open prospective validation.
Schnyder et al. (1993) studied this question.
