Dr Carles Bautista

Consultant paediatric and interventional cardiologist
Specialises in minimally invasive interventional procedures for paediatrics and neonatal cardiology.

Dr Carles Bautista graduated from the University of Barcelona Medical School and went on to complete a Residency in Paediatrics and Paediatric Cardiology at the Hospital Sant Joan De Deu, University of Barcelona. He completed his master’s degree in Science Clinical Research from the University of Barcelona Postgraduate Medical School. 

Dr Bautista has also completed a PhD in Paediatric Pathophysiology from the University of Barcelona Medical School as well as fellowships in Cardiology in Stockholm (Sweden), Tokyo (Japan) and London (UK). 

Clinical expertise

Dr Carles Bautista’s main area of expertise is the diagnosis and treatment of babies and children with cardiac conditions.  His main interest is in the treatment of congenital or acquired heart disease by minimally invasive procedures such as cardiac catheterisation.  

Dr Bautista works as part of a Patent Ductus Arteriosus (PDA) referral team at Harefield hospital to provide a clinical service of excellence for children as well as adults with congenital or acquired heart disease. A PDA procedure avoids the need for open heart surgery in babies and involves inserting a small device made from wire mesh into the heart and blocks the opening to stop the leak. It is guided into place using echocardiography imaging and is the most widely used technique for non-invasive imaging of the heart.   

Research interests

Dr Carles Bautista has research interests in neonatal cardiology, including premature and neonatal intervention, heart monitoring using internet-connected devices, and minimally invasive interventional procedures. He has research interests in the long-term implications of COVID-19 on paediatrics. 


Dr Carles Bautista has numerous articles and studies published on his area of clinical expertise including Transapical mitral Melody® valve-in-valve implantation in a child and Percutaneous management of pulmonary atresia with intact ventricular septum and critical pulmonary stenosis.   

He has also published a study into the Multisystem Inflammatory Syndrome in Children: An International Survey, which describes the presentation, hospital course, and predictors of bad outcome in multisystem inflammatory syndrome in children (MIS-C). 


Dr Carles Bautista is committed to the education of undergraduates and postgraduates who are enrolled on paediatric and adult cardiology courses and is a senior lecturer at the National Heart and Lung Institute, Imperial College London.
