Between 2009 and 2011, she dedicated her professional and personal time to three major missions in Africa and East Jerusalem. Her longest mission was in Sudan, where she worked at the Salam Center for Cardiac Surgery on the outskirts of Khartoum. In this role, she screened patients with suspected or documented cardiac diseases to select those suitable for life-saving heart surgery. In Kenya, she evaluated the suitability for creating a dedicated cardiac surgery unit and provided essential training to local medical staff. In East Jerusalem, she proudly collaborated with a children’s NGO, ensuring that specialised cardiac care reached vulnerable paediatric populations.

- I had my first appointment with Dr Teresa Cadiello and I couldn't be more grateful for the care I received. From the moment I walked in Dr Teresa made me feel completely at ease. She was incredibly kind, empathetic and took the time to truly listen to all my concerns without making me feel rushed. She explained everything clearly and thoughtfully, with her recommendations. I am very grateful for her care and would highly recommend her to anyone looking for a knowledgeable caring cardiologist.
- I am incredibly grateful to have found Dr. Castiello. Unlike previous cardiologists who overlooked my concerns and relied on one-size-fits-all guidelines that never improved my condition, she was extremely thorough and genuinely cared about my case. Dr. Castiello demonstrated a level of competence far beyond any other specialist I have met; she treats the patient holistically rather than just focusing on the heart in isolation. I cannot recommend her highly enough.
- I selected Dr Castiello having been impressed by reading her work and clinical achievements. We had an hour long first consultation the next day and I can honestly say that her knowledge/expertise resulted in a relaxing, calming experience. She is so down-to-earth and listens to every concern you have, which she treats with the utmost importance. She clearly explained everything and eased my anxiety, even offered out-of-hour help. She really is a "top doctor" and I can thoroughly recommend her.
- Dr. Castiello is truly the best cardiologist in London. Exceptionally well-prepared and highly qualified, she combines outstanding expertise with precision and professionalism. Her deep knowledge and extensive training are evident in every consultation. She is thorough, attentive, and genuinely patient-focused, always taking time to listen carefully. Scrupulous and detail-oriented, she inspires complete confidence, making her patients feel safe and truly cared for. I couldn’t recommend her more
- I went to Dr. Castiello on the recommendation of a colleague from work and I definitely recommend her to others. During the analysis of my heart problem, the doctor carefully took into account my pre-existing autoimmune disease. The continuation of my treatment was introduced not only based on textbook guidelines, but also on my individual case and tailored to my specific needs. Dr. Castiello is very dedicated and devotes as much time to the patient as necessary. She is always easy to reach.
- Highly professional and knowledgeable in HCM. Very kind with her time and flexibility to accommodate to the patient’s needs.
- I am writing this review on behalf of my mother who had heart failure associated with other health issues . Teresa help and advice were life saving . With other colleagues she managed to quickly intervened with appropriate intervention to ensure long term recovery .
- There are a few really great doctors and consultants. Dr Castiello is not great, she is simply 'beyond great', quite extraordinary. Bang up to date. Deep listener. Truly empathic. Takes a whole person view. Explains brilliantly. It's rare you recommend someone so so so highly.
- Clearly an expert in the field of myocarditis. Proactive and keen to understand the drivers of the problems.
- Very thorough and assuring
