Acute papillary muscle infarction and rupture in the puerperium complicating Libman-Sacks endocarditis in a patient with systemic lupus erythematosus and antiphospholipid syndrome: a case report.

ABSTRACT:

Background

Acute heart failure caused by severe mitral regurgitation (MR) due to papillary muscle rupture has been described in the puerperium by case reports; however, the majority of cases of papillary muscle rupture are caused by myocardial infarction. We describe papillary muscle rupture occurring in the postpartum period in a patient with systemic lupus erythematosus (SLE), antiphospholipid syndrome (APLS), and chronic Libman-Sacks endocarditis and explore the multifactorial nature of the papillary muscle infarction and rupture in the setting of postpartum fluid shifts, chronic myocardial injury from Libman-Sacks, and high thrombotic risk.

Case summary

A 29-year-old woman presented with acute heart failure 2 weeks' postpartum and was found to have acute MR due to a flai
