Risk factors for sudden death after repair of tetralogy of Fallot

Postmortem computed tomography for detecting causes of sudden death in infants and children: retrospective review of cases

“…For example, sudden death due to ventricular arrhythmia often occurs after surgery for TOF (case 3). 25,26 In cases to be classified as sudden infant death syndrome (SIDS) without preexisting disease, the possibility of various infectious diseases or congenital errors of metabolism may also be considered. [27][28][29][30][31][32][33] Nontraumatic PMCT findings are classified into three categories: (1) cause of death (e.g., pneumonia); (2) postmortem changes (e.g., hyperattenuating aortic wall, 34 hypostasis, 35 dilatation of the right heart 36 ; and (3) changes that occurred after CPR (e.g., GI distention, hepatic portal venous gas, 16 cardiovascular gas 37 ).…”

Peak oxygen uptake, ventilatory efficiency and QRS-duration predict event free survival in patients late after surgical repair of tetralogy of Fallot

“…In tetralogy of Fallot the majority of deaths are due to ventricular arrhythmias, progressive heart failure and re-operations [4,5,7,[20][21][22]. In an initial study on mechano-electrical interaction, Gatzoulis et al [3] showed that QRS prolongation is related to increased right ventricular size and predicts malignant ventricular arrhythmias and sudden death.…”

A new pulmonary valve cusp plasty technique markedly decreases transannular patch rate and improves midterm outcomes of tetralogy of Fallot repair

“…Exercise testing has shown that functional status is impaired in TOF patients with longterm PI [11,12]. Image examination of TOF patients late after repair has shown that PI is closely associated with TAP and that PI results in marked RV dysfunction, even in asymptomatic patients [13,14].…”
