Eclipsed mitral regurgitation successfully treated with a combination of surgical and pharmacological therapies: a case report.


ABSTRACT:

Background

Eclipsed mitral regurgitation (MR), which is characterized by a transient and reversible massive functional MR, usually causes recurrent episodes of acute pulmonary oedema in patients with a preserved left ventricular ejection fraction. The pathophysiological mechanism and optimal treatment of eclipsed MR are not yet fully understood.

Case summary

A 72-year-old woman was hospitalized with cardiogenic shock and takotsubo cardiomyopathy. After hospitalization worsening dyspnoea again appeared, and urgent transthoracic echocardiography revealed severe MR, which spontaneously resolved in a few minutes. At this point, eclipsed MR was detected for the first time. Diagnostic examination revealed that the eclipsed MR was caused by a left ventricular afterload increase. Ultimately, the patient began medical therapy and underwent mitral valve replacement. The subsequent clinical course was favourable.

Discussion

This case illustrates the importance of early intervention for eclipsed MR. A combination of surgical and pharmacological therapies can serve as one treatment option for an eclipsed MR.
