“…17 Several succeeding case reports showed reoperations of the Björk pathway using a bioprosthetic valve. [18][19][20] In group P patients of our series, four interventional and four surgical valve implantations into the RA-RV connection were performed. Two patients underwent TCPC conversion; one patient received the TCPC conversion in the early era.…”

Background: This study aims to evaluate clinical outcomes and hemodynamic variables late after the Björk procedure, regarding the pulmonary flow pattern. Methods: Patients who survived more than 15 years after the Björk procedure were included and then divided into two groups according to their pulmonary flow pattern by pulsed-wave Doppler assessment of echocardiography: patients with pulsatile systolic pulmonary flow (Group P) and those without (Group N). Results: A total of 43 patients were identified, of whom 13 patients were divided into Group P and 30 in Group N. Median age at the Björk procedure was 5.7 (2.1-7.3) years, and median follow-up was 32 (28-36) years. Survival after 15 years was higher in Group P, compared with Group N (100% vs 76% at 30 years, P = .045). Cardiac catheterization data demonstrated higher cardiac index in Group P patients compared with Group N patients (3.5 vs 2.8 L/m2, P = .014). Cardiac magnetic resonance imaging study revealed that Group P patients had higher right ventricular end-diastolic volume index (96 vs 57 mL/m2, P = .005), higher end-systolic volume index (49 vs 30 mL/m2, P = .013) and higher right ventricular stroke volume index (48 vs 25 mL/m2, P < .001), compared with Group N patients. Exercise capacity tests demonstrated that Group P patients showed a higher percent predicted peak oxygen consumption, compared with Group N patients (73 vs 58%, P < .001). Conclusions: Late after the Björk procedure, patients with a pulsatile systolic pulmonary flow had a larger right ventricle and better exercise capacity compared with those without pulsatile systolic pulmonary flow.

Rarely performed nowadays, the Björk procedure is an alternative to the Fontan palliation for biventricular repair in patients with tricuspid atresia. The right atrium to right ventricle conduit failure leads to serious long-term complications. The management of such patients at high surgical risk remains challenging. We report a successful reoperation in a young adult 25 years after the modified Björk intervention, who presented with severely narrowed and calcified valved conduit.
