“…Among these arrhythmias, AF has been identified as a risk factor for decreased survival rates in patients with repaired TOF, particularly in those with TR [ 114 , 117 ]. The primary factor contributing to atrial arrhythmias in these patients is enlargement of the right atrium in these patients [ 114 , 118 ]. As right atrial dilatation is a risk factor for recurrent atrial tachyarrhythmia in patients with late repair of TOF who undergo PVR and atrial arrhythmia surgery [ 118 ], anti-arrhythmic surgery should be considered simultaneously with PVR to reduce the recurrence of atrial arrhythmia [ 119 ].…”

OBJECTIVES The impact of residual pulmonary stenosis (rPS) or right ventricular (RV) outflow tract obstruction on prognosis after surgical pulmonary valve insertion (SPVI) in repaired tetralogy of Fallot (TOF) patients with pulmonary regurgitation (PR) remains controversial. rPS assessment is partially dependent on RV contractility. We investigated the impact of rPS according to RV ejection fraction (RVEF). METHODS In this multicentre, retrospective study, 117 repaired TOF patients who underwent SPVI for more than moderate PR between 2003–2021 were examined. Regarding rPS, the threshold for PR with rPS (PSR) and PR was 25 mmHg. For RVEF, the threshold for preserved RVEF (pEF) and reduced RVEF (rEF) was 40%. The patients were divided into four groups: patients with PR and pEF (PR-pEF) (n = 48), those with PR and rEF (PR-rEF) (n = 44), those with PSR and pEF (PSR-pEF) (n = 16), and those with PSR and rEF (PSR-rEF) (n = 9). Clinical parameters, postoperative adverse event rates, and their associations were studied. RESULTS The 5-year freedom from adverse cardiovascular events was the highest in the PSR-pEF and the lowest in the PSR-rEF groups. The PSR-rEF group had the highest RV end-diastolic pressure (RVEDP) (12 ± 2.2 mmHg) (p = 0.006). From multivariable analysis, RVEDP was associated with postoperative adverse events (p = 0.016). RVEDP > 8mmHg was associated with a lower freedom from adverse events. CONCLUSIONS The freedom from adverse events was the lowest in the PSR-rEF group, with the highest RVEDP, suggesting RV systolic and diastolic dysfunction. Reduced RVEF may mask the intrinsic degree of residual stenosis, delay SPVI timing, and increase adverse events.
