An 11-year-old girl, with 25 mm mosaic tissue valve presented with clinical and echocardiographic appearance of stenotic mitral valve prosthesis. Her condition was treated via a transcatheter valve-in-valve implantation using a 23 mm Edwards Sapien 3, with satisfactory outcome.

The Novel Coronavirus 2019 (SARSCoV- 2), which was first reported on in Wuhan, China, in late December 2019, causes a respiratory illness called COVID- 19 Disease. COVID-19 is most likely causing a hypercoagulable state, however the prevalence of acute venothromboembolism is still unknown. Limited data suggest pulmonary microvascular thrombosis may play a role in progressive respiratory failure. Here, we report a case of a child with an unusual presentation of COVID-19 presented initially by dry cough without fever and complicated by massive acute pulmonary embolism and lung infarction and treated successfully by hydroxychloroquine and azithromycin, in addition to anticoagulant therapy.

Iatrogenic aortopulmonary (AP) fistula is an unusual complication after balloon pulmonary artery (PA) angioplasty or branch pulmonary arteries (PAs) stent dilation. The majority of the cases were reported after transcatheter interventions on the PAs or right ventricular outflow tract (RVOT), in patients with transposition of great arteries (TGA) who underwent PA angioplasty following arterial switch operation (ASO) or after transcutaneous pulmonary valve replacement in patients who had undergone a Ross procedure [1].We present a case of iatrogenic AP fistula in a 4-year-old patient with a history of repaired truncus arteriosus type 1 followed by bilateral PAs stent placement and balloon dilation,17 months later redilation of the right pulmonary artery (RPA) stent resulted in a AP fistula with significant left to right shunt which was successfully closed with a covered stent. This case demonstrates a previously unreported complication of transcatheter RPA stent reintervention after truncus arteriosus repair.
