Dr Dalby trained at St Mary’s Hospital in Paddington then went on to study for his MD at the Royal Brompton Hospital.
Subsequently, he visited the Pitie Salpetriere Hospital, Paris and the Charlles Nicole Hospital, Rouen as part of his clinical training, and was involved in the first in man percutaneous aortic valve replacements with Professor Alain Cribier in Rouen.
Dr Dalby attained the French postgraduate diploma in Interventional Cardiology and returned to the UK to complete his training.
Areas of expertise
Dr Dalby specialises in interventional cardiology, including coronary angioplasty and stent placement. He has helped set up Harefield Hospital's international reputation in primary angioplasty for heart attack victims and has presented papers on the service in the UK and internationally.
The hospital's primary angioplasty service has one of the fastest ‘door to procedure’ rates in the country - the rate of response plays a crucial role in the procedure's success.
Dr Dalby has expertise in multivessel angioplasty, stenting, catheterisation and angioplasty using the radial (wrist) route as well as the standard femoral (leg) route.
He also treats heart failure, palpitations and cardiac arrhythmias, with a specialist interest in adult structural heart disease. He is a member of the percutaneous valve group, which is developing percutaneous strategies to treat acquired valvular lesions.
Dr Dalby's research interests include strategies and logistics of primary angioplasty for acute myocardial infarction. He also conducts research into the structural and functional analysis of intracoronary thrombus during acute myocardial infarction.
In 2007, Dr Dalby presented his research demonstrating how swiftly delivered primary angioplasty increases the chances of surviving a heart attack to the British Cardiovascular Society meeting in Glasgow.

Dr Dalby made one of the winning case presentations at the Transcatheter Cardiovascular Therapeutics meeting in Washington in 2006.
He also leads a research group investigating the biology of intracoronary stents, particularly with regard to the possible risks and benefits of ‘drug-eluting stents’ including high-resolution intracoronary imaging with optical coherence tomography.
As a fellow of the European Society of Cardiology, he presented at their annual conference in Munich, and also joined the Faculty of the US Transcatheter Therapeutics at their meeting in Miami in 2012 to discuss aspects of heart attack management.
Dr Dalby teaches Imperial College London medical students and postgraduate doctors for membership of the Royal College of Physicians.
He was also a speaker at the first European Interventional Cardiology Fellows course in London in 2007.
Reviewing and committee work
Dr Dalby has acted as a reviewer for International Journal of Cardiology, Circulation and the European Journal of Cardiology.
He serves on the committee of the North West London Cardiac Network Primary Angioplasty Group and the North West London Cardiac Network Percutaneous Aortic Valve Group.
