Successful management of heart failure 45 years after surgical correction of tetralogy of Fallot.

ABSTRACT: A 59-year-old Japanese woman was admitted with heart failure due to severe pulmonary regurgitation and tricuspid regurgitation, in addition to atrial fibrillation 45 years after surgical correction of tetralogy of Fallot (TOF). She had been under treatment with medication and catheter ablation for arrhythmia including ventricular tachycardia for the past 28 years. She underwent pulmonary valve replacement as well as tricuspid and mitral valvuloplasty, which obviously improved her status even though her right ventricular end-diastolic volume index exceeded the recommended threshold. Patients who have undergone surgical correction of TOF need to be managed over the long term. <Learning objective: For a long term after surgical correction of tetralogy of Fallot (TOF), appropriate managements are needed for arrhythmia and heart failure related to heart valve disease. Even though her right ventricular end-diastolic volume index exceeded the recommended threshold by the current published guidelines, re-operation for heart valve diseases improved the present patient. We have to accumulate evidence to make useful guideline of re-operation of TOF in Japan.>.

Project description:BackgroundMicroRNAs (miRNAs) are a class of regulatory RNAs that regulate gene expression post-transcriptionally. Little, however, is known on the expression profile of circulating miRNAs in Tetralogy of Fallot (TOF) patients late after surgical repair. In this study, we aimed to identify the specific patterns of circulating miRNAs in blood of patients with repaired, non-syndromic TOF and to assess whether these specific miRNAs may be useful to differentiate patients with and without heart failure.MethodsSurePrint™ 8 × 60 K Human v16 miRNA arrays were used to determine miRNA expression profiles in 15 healthy controls and 37 patients after TOF repair of whom 3 had symptomatic right heart failure. The expression levels of selected miRNAs have been validated by quantitative reverse transcription polymerase chain reaction (RT-qPCR). Enrichment analyses of altered miRNA expression were predicted using bioinformatic tools.ResultsCompared with healthy controls, a total of 49, 58 and 77 miRNAs were found to be significantly altered in TOF patients (TOF-all), TOF patients with (TOF-HF) and without symptomatic right heart failure (TOF-noHF) (>2.0-fold change, adjusted P < 0.05), respectively. Three miRNAs namely miR-181d-5p, miR-206 and miR-625-5p were validated by RT-qPCR in all TOF groups. The area under the receiver operating characteristic curve (AUC) for miR-181d-5p, miR-206 and miR-625-5p were 0.987, 0.993 and 0.769 in TOF-all and 0.990, 0.994 and 0.749 in TOF-noHF, respectively. Moreover, expression levels of miR-625-5p, miR-1233-3p and miR-421 were lower in TOF-HF compared to TOF-noHF (P = 0.012).ConclusionsAltered expression levels of circulating miRNAs were found in TOF patients late after surgical repair and are different to those seen in the right ventricular myocardium of infants with TOF. Expression levels of miR-421, miR-1233-3p and miR-625-5p are lower in TOF patients with symptomatic right heart failure and thus may indicate disease progression in these patients.
