Background:Heart failure (HF) is an important complication in adults with congenital heart disease (CHD), but because only a few studies have focused on acute HF hospitalization in adults with CHD, we study aimed to define the clinical characteristics of such patients and examine the differences in acute HF between adults with CHD and acquired heart disease.
Methods and Results:We retrospectively evaluated 50 adults with CHD admitted for treatment of acute HF and compared their data with those from Japanese HF registries. Patient mean age was 37±15 years and 58% were male. In total, 86% of the patients had complex forms of CHD and 62% had undergone corrective surgery, including the Fontan procedure; 66% of patients showed right heart hemodynamic abnormality. In-hospital mortality was 4%, which was comparable to the Japanese HF registries. Survival rate was 93% at 1 year and 75% at 3 years, which was similarly poor to the rates of HF secondary to acquired heart disease.
Conclusions:We clarified the clinical characteristics of adults with CHD requiring HF hospitalization. Young adults with complex CHD were hospitalized for management of acute right HF. Short-term and mid-term outcomes were similarly poor compared with acute HF secondary to acquired heart disease.
