Dr. Assen Keltchev, MD, PhD, has joined the network of leading medical specialists partnering with the i‑Health platform. He will serve as a cardiac surgery consultant. Providing patients with access to established and trusted specialists is extremely important to us. We are delighted to welcome Dr. Assen Keltchev as an i‑Health partner.
Through i‑Health, Bulgarian and international patients can request a cardiac surgery consultation or second medical opinion. Dr Kelchev consults patients with heart valve and aortic diseases. Patients with coronary artery disease or those requiring heart valve replacement can also seek his expert opinion. Each case is assessed individually to determine whether cardiac surgery is needed.
Consultations take place at Acibadem City Clinic Vitosha University Hospital. The hospital is located at 1 Konstantin Pomyanov Street, Dragalevtsi, Vitosha District, 1415 Sofia, Bulgaria.
When requesting a second medical opinion, patients must provide their available medical records in advance. These may include hospital discharge summaries, diagnostic imaging and the results of previous medical consultations.
The i‑Health team assists with arranging the appointment and communicating with the hospital. If necessary, we can also arrange the translation of international patients’ medical documents.
Each request is reviewed individually. The date and time of the consultation are confirmed in advance and depend on the specialist’s availability.
To request a cardiac surgery consultation or second medical opinion with Dr. Assen Keltchev, please submit an enquiry through the i‑Health platform and attach all available medical records.
