Successful Late Repair of Truncus Arteriosus: A Single Center Experience

Background: Truncus arteriosus is a rare congenital heart defect resulting from the failure of the truncus arteriosus to divide during fetal development. It leads to a single outflow tract from the heart and, if left untreated, can be fatal. Late presentation and repair can also increase the risk of pulmonary hypertensive crises, which can lead to morbidity and mortality after repair. Methods: We performed a retrospective study examining outcomes of late-presenting patients who were repaired for this anomaly at our institution. Results: We identified seven patients who underwent late repair of truncus arteriosus who were 3 to 11 years of age. There were six females and one male. Postoperatively, all patients showed improvement in symptoms and hemodynamic parameters, with no reported mortality. The median duration of stay in the intensive care unit was nine days and with a range from 3 to 18 days, while the median hospital stay was 29 days with a range from 21 to 60 days. Conclusion: These findings highlight the potential for successful outcomes even in cases of delayed diagnosis.

Expanding Valve Repair in Rheumatic Heart Disease

Rheumatic heart disease is a serious ailment with significant morbidity and mortality in endemic areas; yet, there is no agreement on indication, timing, and surgical modality for treating rheumatic valve affection. There is mounting evidence that rheumatic mitral valve repair is possible with good long-term results, less is the case with rheumatic aortic valve disease. We discuss the surgical approach for both valves emphasizing the role of multimodality imaging.
