RESUMEN
Background: Although primary definitive repair of congenital heart disease has become the preferred management approach, pulmonary artery banding (PAB) remains a valuable palliative procedure used to restrict pulmonary blood flow in certain conditions. However, when the band is to be removed, another surgical intervention is usually required. Methods: To describe percutaneous removal of pulmonary artery band, the medical records of patients who underwent this procedure were reviewed. Results: Between 2000 and 2020, 143 patients underwent PAB. Of these, we attempted balloon debanding of the pulmonary artery in four patients. At the time of the procedure, the average age of patients was 36 ± 6.24 months, and their average weight was 12.37 kg. Band removal via catheter was successful in three cases and was associated with an adequate reduction in pressure gradient across the pulmonary artery band site (average of 71.67 ± 12.58 to 23.67 ± 2.89 mm Hg). None of the patients experienced complications during or after the procedure. Follow-up data after discharge (3-10 years) provides reassuring and satisfactory results. Conclusion: Based on our findings, we suggest that percutaneous removal of the pulmonary artery band might be a safe and effective alternative to surgical debanding. However, studies with a larger sample are required for further clinical implementation of the technique.
RESUMEN
We herein report on a series of four patients presented to our tertiary care centre with features of multisystem inflammatory syndrome in children and cardiac involvement. Two of our patients had recent exposure to a COVID-19-positive patient, one had recent documented infection, and another had no known positive contact. All the patients were tested positive for severe acute respiratory syndrome coronavirus 2 immunoglobulin G antibody at the time of presentation. All of them fulfilled the diagnostic criteria according to the World Health Organization Centers for Disease Control or the British guidelines for MIS-C (fever for ≥3 days, multisystem involvement (at least two), elevated markers of inflammation, and no other alternative diagnosis).Cardiac involvement was variable ranging from isolated ectasia of the coronary arteries to full-blown pancarditis such as severe biventricular dysfunction, multi-valvar involvement, and pericardial effusion.All our patients received intravenous immunoglobulin (2 g/kg), methylprednisolone, and aspirin and some required inotropic support and ICU admission.Remarkably, all our patients showed significant improvement in their cardiac disease within a few days as evident on serial echocardiographic evaluation. However, we stress the need for long-term follow-up as one of our patients demonstrated mild LV myocardial scarring as evident by gadolinium late enhancement on a cardiac MRI.

We report on an 8-year-old boy, who presented to the emergency department at our institution with fever, generalised oedema and hypotension. Investigations revealed anaemia, thrombocytopenia in addition to elevated serum inflammatory markers, a negative COVID-19 PCR test and a positive COVID-19 IgG. His echocardiography was consistent with carditis in otherwise morphologically normal heart with depressed cardiac function, moderate-to-severe mitral valve regurgitation, moderate tricuspid regurgitation with an estimated right ventricular systolic pressure half systemic, trace aortic regurgitation, bilateral small pleural effusions, distended inferior vena cava and normal coronaries. He was started on inotropic support, intravenous immunoglobulin and methylprednisolone, and was transferred to the paediatric intensive care unit. To the best of our knowledge, this was the first case of multisystem inflammatory syndrome in children encountered in Lebanon. The presentation and management were thoroughly described in this article aiming to share our experience and to contribute to the rapidly emerging literature on this syndrome.
