Clinical interests

Dr Kanaganayagam is a cardiology specialist and lead clinician in heart failure for a large community service for Imperial College Healthcare and sees patients in a local clinic with chest pain, breathlessness, blackouts and palpitations.

With sub-specialist expertise, and formal accreditation, in multi-modality imaging he runs his own valve service, which allows a comprehensive assessment, including the use of 3D transoeophageal when necessary after advanced transthoracic echocardiographic assessment. He uses his specialist multi-modality imaging knowledge to help assess suitability for, and guide transcatheter procedures such as TAVI, PFO/ASD/LAA closures, in a clinical team.

Dr Kanaganayagam also sees patients for risk assessment when concerned or who have developed chest pain and directly performs non-invasive assessment when suitable with stress testing or CT scanning, and performs invasive coronary angiography when necessary.
