Cróchán graduated from NUI Galway in 2004 and underwent basic medical training in the Mater Hospital in Dublin and Mayo Clinic, Rochester.  He then underwent Cardiology specialist training in the Mater Hospital and St. Vincents Hospital, Dublin. In 2011 he was awarded the Dr. Richard Steeven's Scholarship by the HSE to undertake subspeciality training in Interventional Cardiology and Transcatheter Aortic Valve Implanatation (TAVI) in Bern University Hospital, Switzerland. 

He was awarded a research grant by the European Society of Cardiology (ESC) to perform clinical research in TAVI from which he generated over 60 peer reviewed publications and was awarded his PhD in 2015. 

In 2014 he was appointed Consultant Interventional Cardiologist at Triemli City Hospital, Zurich and Assistant Professor in Bern University, Switzerland where he worked for 4 years from July 2014 until March 2018.  He subsequently spent 3 months performing advanced structural heart interventions at Karolinska University Hospital, Stockholm (minimally invasive TAVI, MitraClip, PFO and ASD Closure, and Cardioband).  He is a Fellow of the European Society of Cardiology (FESC) and his practice involves both General and Interventional Cardiology with a special interest in structural heart disease interventions.
