About Dr Konstantinos Vakalis

Dr. Konstantinos Vakalis is a highly regarded Consultant Cardiologist based in London, UK, with clinical appointments at Queen Elizabeth Hospital (Lewisham and Greenwich NHS Trust) and Harefield Hospital (Guy’s and St Thomas’ NHS Trust). He has extensive training in cardiology from both Greece and the UK, and holds prestigious fellowships, including Fellow of the European Society of Cardiology (FESC) and Fellow of the European Association of Cardiovascular Imaging (FEACVI). His primary areas of expertise include cardiovascular imaging and heart failure, with a particular focus on stress echocardiography, where he is regarded as a leader in the field.

At Queen Elizabeth Hospital, Dr. Vakalis leads the heart failure program and oversees the Echo Multidisciplinary Teams (MDTs), providing crucial imaging support in both theatres and the catheterisation lab. He is also a Consultant Cardiologist at OneWelbeck, where he performs complex stress echocardiography, transoesophageal echocardiography (TOE), advanced echocardiographic studies, and runs CT coronary angiography lists.

Previously, Dr. Vakalis served as an Honorary Consultant Cardiologist at Ashford and St Peter's NHS Trust, where he managed the stress echocardiography list. During his tenure as a Clinical Fellow in Echocardiography at Harefield Hospital, he introduced a new hybrid stress echo protocol and contributed to securing European accreditation in Advanced Stress Echocardiography (EACVI). He has also held senior clinical positions in both the NHS and private healthcare sectors, including running a busy cardiology department at a private medical centre in Ioannina, Greece.

Dr. Vakalis earned his Bachelor of Medicine from the University of Ioannina, Greece, in 2004, and has continuously pursued professional development through advanced certifications in adult transoesophageal and transthoracic echocardiography, as well as CT coronary angiography.
