Pulsed Levosimendan in advanced heart failure due to congenital heart disease: a case series

BACKGROUND: Levosimendan is a non-adrenergic calcium-sensitizing agent with positive inotropic and vasodilatory effects. Its use in acute decompensation of heart failure is established. Good evidence now exists for repetitive infusions of Levosimendan to improve symptoms and reduce hospitalization in advanced heart failure (AdHF) populations. Its use in heart failure resulting from congenital heart disease is not yet commonplace. CASE SUMMARY: We present three cases in which pulsed Levosimendan was used in the management of AdHF secondary to underlying congenital heart disease. There was symptomatic and biomarker evidence of improvement. DISCUSSION: Intermittent Levosimendan may represent a valuable therapy to reduce hospitalization and improve quality of life in adults with congenital heart conditions.
