“…During the early postoperative period, residual anatomical abnormalities or complications may necessitate corrective interventions following Fontan surgery. Such early resurgeries carry the risk of high morbidity, and Fontan take-down procedures are associated with elevated mortality rates [4]. In response to these challenges, transcatheter interventions have emerged as a pivotal alternative, strategically employed to mitigate potential complications in the critical early postoperative phase after Fontan surgery.…”

Mortality following Fontan surgery has signi cantly decreased; however, postoperative morbidity rates remain high and can lead to unfavorable outcomes. Early post-Fontan pathway obstructions can result in persistent pleural effusion, cyanosis, and low cardiac output syndrome (LCOS). Transcatheter interventions can be employed as an alternative to early re-surgery for their treatment. Over a 13-year study period, early (<30 days) transcatheter interventions were performed on 37 (10.4%) of 344 patients who underwent Fontan surgery. Case notes and procedure records were retrospectively reviewed. Among them, 33 patients were treated solely with transcatheter procedures, while 3 were lost during early ICU follow-up. 30 patients were successfully treated with purely transcatheter methods and were discharged. After left pulmonary artery (LPA) balloon angioplasty, one patient required emergency surgery. In another case, LPA stent implantation resulted in thrombosis followed by localized tissue plasminogen activator (TPA) administration and subsequent middle cerebral artery (MCA) stroke. In four cases, transcatheter interventions were inadequate, necessitating early re-surgery, of which two patients died. The median age at Fontan operation was 4.8 (IQR:4-9.4) year, with a median weight of 16.5 (IQR:15-25.2) kg. Among the 23 patients with persistent pleural effusion/ascites, transcatheter procedures; fenestration dilatation in 14 patients, LPA stent placement in 7 patients, right pulmonary artery (RPA) stent placement in 4 patients, occlusion of aortopulmonary (AP) collaterals in 5 patients. All 8 patients diagnosed with LCOS underwent fenestration dilation. Procedural mortality was not observed. Early post-Fontan transcatheter interventions appear safe and effective.

“…The article by Marathe and colleagues 5 in the current issue of the Journal is a welcome addition to the understanding of long-term outcomes following Fontan takedown in Australia and New Zealand. Over a 43-year study period, the authors found 36 of 1540, or 2.3%, had a Fontan takedown.…”
