Coronary artery fistula is a rare but well-documented complication of right ventricular endomyocardial biopsy, particularly in the adult population. Typically, these fistulae never reach clinical or hemodynamic significance, but some may cause coronary steal and ventricular dysfunction. We report a case of a significant coronary artery fistula requiring device closure in the cardiac catheterization laboratory with subsequent improvement of clinical symptoms and cardiac function.

I read with interest the article by Haddad et al concerning the bench testing of BeSmooth peripheral tests, and I would like to share some thoughts and highlight few points.

BeSmooth stent is behaving like any pre-mounted stent available on the market. None can achieve the Holy Grail of being dilatable to adult size without losing their integrity. Until dedicated stents are available, pre-mounted stents are preferred to unmounted stents because of their better profile and deliverability. Technically, proper post-dilatation should be performed in order to avoid and extensive foreshortening and the formation of a ring that would limit further expansion of the stent. BeSmooth stent like other pre-mounted stents can also be used without restriction in situations where overexpansion is not required.

BeSmooth stent platform with the knowledge of its intrinsic properties is, in our opinion, a good add-on to the armamentarium of pre-mounted stents used in paediatric cardiology.

Saccular aneurysms of the aorta in childhood are rare, and the low incidence of aortic aneurysms among children limits our understanding of their aetiology and surgical indications. In this case report, we describe the successful surgical treatment of a 5-year-old boy with severe aortic valvular stenosis, supra-valvular aortic stenosis, and a large saccular aneurysm in the anterior wall of the ascending aorta, without any connective tissue disorder.

Herein we present the right ventricular dissection and describe its successful management after arterial switch operation in a full-term male neonate. There are no evidence-based recommendations for the management of this rare complication. Our management included veno-arterial extracorporeal membrane oxygenation placement and delayed surgical evacuation of the dissecting haematoma with beneficial outcomes.

Inflammatory myofibroblastic tumour of the heart is an exceedingly rare benign neoplasm. While benign, without prompt management its impact can be devastating. Tetralogy of Fallot with absent pulmonary valve is a rare form of CHD. We present the first documented case of inflammatory myofibroblastic tumour of the heart in the presence of tetralogy of Fallot with absent pulmonary valve.
