Introduction: Heart failure is a well-known public health problem with a high mortality rate for patients. It is a condition in which the heart can not draw enough blood and oxygen needed for the functioning of the organism. Many patients have a heart transplant ultimate therapy when they have advanced heart failure. Due to the lack of organ donors, there is a great risk for further decompensation and frequent deaths for patients. The lack of donors has led to the development of effective mechanical vascular support. The implantation of the entire artificial heart is one of the possibilities of surgical treatment and represents the bridge to heart transplantation. Artificial heart provides mechanical vascular support in decompensated patients with heart failure. Purpose: The purpose of the diploma work is to present the patient medical care at the theoretical level after the insertion of an artificial heart in the intensive care unit. Methods: Descriptive method of work is be used with a critical overview of slovene and foreign professional and scientific literature. The basic literature was searched using the CINAHL, PubMed, MEDLINE and Cochrane Collaboration databases through remote access to the Faculty of Medicine for Nurses in Ljubljana. The publication of relevant literature is also through a reciprocal bibliographic catalog database and the Google Scholarly Web of Science. The published litter was used from 2005 to 2017. Discussion and conclusion: Unfortunately, heart transplantation, as the best and fastest solution for advanced heart failure, is not immediately possible for all patients. One solutions is to insert a temporary artifical of the heart in which the patient's chamber replaces the artificial heartbeat. After the operation, the patient needs help in performing all the basic activities. The most important are exposed to respiration, maintaining normal body temperature, eating and drinking, secreting and separating, personal hygiene and orderliness, sleep and rest, movement and the appropriate position of the patient. The nurse caring for nursing needs knowledge, skills and experience, and it is important to constantly gain new knowledge.
