Biography

Mr Guido Michielon is the lead congenital surgeon at Royal Brompton Hospital, where he treats private and NHS patients. Mr Michielon is a recognised specialist for congenital heart surgery in the international scientific community. He is enrolled in the GMC Specialist Registry for Cardiothoracic Surgery. 

He studied at Padua University, Italy, graduating with the highest honour (summa cum laude). He completed his clinical training in cardiac surgery in the USA, where he spent five years working in some of the country’s most renowned cardiac departments. This included Mayo Clinic, Boston Children’s Hospital and the Children’s Hospital of Philadelphia. He has complete surgical training in congenital, paediatric and neonatal cardiac surgery.

In 2001, he took on the position of attending paediatric cardiac surgeon at Bambino Gesù Children’s Hospital in Rome, Italy, where he was granted the title of “top specialist” in aortic root and paediatric valve repair.

Between 2012 and 2015 he was appointed as a paediatric cardiothoracic surgeon at University Medical Centre Groningen in the Netherlands.

Mr Michielon joined Royal Brompton and Harefield Hospitals in 2015 as a consultant in paediatric cardiac surgery with special interest in neonatal surgery. He is currently the Clinical Lead for congenital heart surgery at the Royal Brompton Hospital.

Clinical expertise

Mr Michielon is an experienced cardiac surgeon and has performed over 3,000 open heart procedures in congenital and paediatric cardiac surgery. He can perform the whole spectrum of congenital cardiac procedures with a special focus on neonatal surgery, including:

  • neonatal repair of complex congenital heart diseases, including Norwood operation for HLHS and arterial switch operation for transposition of the great arteries
  • aortic arch reconstruction
  • aortic root surgery (including Ross and Ross-Konno procedures)
  • aortic valve repair
  • valve-sparing procedures (including the “Cone” procedure for Ebstein's anomaly and mitral valve repair in the paediatric population).

Mr Michielon has special expertise in the three-stage Norwood procedure heart surgery for hypoplastic left heart syndrome, having been trained as Chief Resident by Professor Norwood himself.  This includes:

  • Norwood stage one procedure
  • comprehensive Norwood stage two procedure
  • Norwood stage three Fontan completion procedure.

Additionally, his expertise includes:

  • arterial switch operation for transposition of the great arteries with complex coronary artery patterns
  • primary repair of all neonatal emergencies
  • complex neonatal aortic arch reconstruction
  • neonatal repair of pulmonary atresia (PA) ventricular septal defect (VSD)
  • repair of PA-VSD-MAPCAs (Major Aorto-Pulmonary Collateral Arteries) with unifocalisation of MAPCAs.
  • Mr Michielon also has a special expertise in aortic root surgery, including the Ross operation, complex mitral valve repair in paediatric patients and “Cone” operation for Ebstein’s anomaly.

He has valuable experience in heart transplantation for congenital heart disease (CHD). Also he is experienced at implanting the 'Berlin Heart' pneumatic pulsatile paediatric assist devices, which can be a bridge to heart transplantation.

In 2010, he was part of the surgical team that implanted the first axial flow pump – the Jarvick 2000 – in a paediatric patient with heart failure.

Research interests

Mr Michielon’s main interests focus on single ventricle palliation and the Fontan procedures. He has coordinated and published multi-institutional European studies on behalf of the European Congenital Heart Surgeons Association (ECHSA) on this subject. He recently published an important paper on interstage management after the Norwood stage one operation, based on the clinical experience he coordinated at Brompton Hospital during the last 5 years.
