Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital anomaly. The usual clinical course is severe left sided heart failure and mitral valve insufficiency presenting during the first months of life. However, in some cases collateral blood supply from the right coronary artery is sufficient and symptoms may be subtle or even absent. Arrhythmias or sudden cardiac death in adult life may be the first clinical presentation in patients with ALCAPA. We report a case, where a 39-year old woman presented with ventricular fibrillation during phycial exertion. Coronary angiography and CT-angiography revealed an anomalous origin of the left coronary artery, and an aortic reimplantation of the left coronary artery was performed followed by ICD implantation. A review of the literature on ALCAPA is presented along with CT images before and after surgery.

The vast majority of the patients seemed to live normal lives 20-37 years after Tetralogy of Fallot repair. Late deaths were cardiac in origin, including sudden death from arrhythmias. The number of late reoperation has been low. Considering the natural history of the disease, Fallot repair has proven to be a beneficial procedure even including the very early experience short after introduction of open heart surgery.

OBJECTIVES The aim was to investigate the incidence of infective endocarditis (IE) in right ventricle-to-pulmonary artery conduits implanted at a Danish tertiary centre. METHODS Cases of IE in patients with homografts, Contegra grafts and Melody transcatheter valves were evaluated retrospectively with regard to the likeliness of the diagnosis using the modified Duke criteria and the likeliness of conduit involvement. Incidence rates for IE were calculated 1 and 5 years after valve implantation for all 3 conduits, and separately for Melody subgroups depending on which conduit served as landing zone. Cox regression with time-dependent covariates was used to model the impact of the conduit type on the incidence of IE. RESULTS Annualized incidence rates of IE in homografts, Contegra grafts and Melody valves were 0.40% (0.40 cases per 100 patient-years), 0.97% and 6.96% 1 year and 0.27%, 1.12% and 2.89% 5 years after valve implantation. Hazard ratios (HRs) were 3.20 [95% confidence interval (CI) 0.91–11.17, P = 0.069] for Contegra grafts and 11.89 (95% CI 2.91–48.48, P < 0.001) for Melody valves compared to homografts. CONCLUSIONS Bovine pulmonary conduits were more prone to endocarditis, with Melody valves being the most frequently infected. HRs for the risk of suffering from endocarditis were substantially higher for Melody valves and Contegra grafts compared to homografts, although this finding was only statistically significant for Melody valves and not for Contegra grafts.

OHT is an excellent surgical option for late FF with impaired ventricular function. Protein dispersion improves with OHT, but PLE negatively affects the mid-term OHT outcome, mainly for early infective complications.
