Aim: Left ventricular assist device (LVAD)is one of the treatment method of advanced heart failure. LVAD, which are used to bridge heart transplantation in the early period, are now increasingly used as destination therapy due to the limited number of heart transplant donors. As the time spent with LVAD increases, complications increase. The most mortal of these complications is LVAD thrombosis. It is very important to clarify the risk factors in order to prevent this mprtal complication. Material and Methods: Between April 2012 and January 2020, a total of 80 LVAD patients were evaluated retrospectively. Demographic characteristics, co-morbidities, preoperative examinations, LVAD data records of the patients were recorded from the database. Tricuspid valvw annular motion measurement (TAPSE) value was used in echogradiogram examinations performed in the preoperative period to evaluate the contractile functions of the right ventricle. Results: A total of 60 patients included in the study. Patients divided into two according to right ventricular functions. Normal or mildly affected right ventricular functions (TAPSE≥17) and modarete or severely affected right ventricular functions (TAPSE<17). While there were 28 (%46.7) patients in normal or mildly affected group (TAPSEN); There were 32 (%53.3) patients in moderately or severely affected group (TAPSED). There was no statistical difference between the groups in terms of age, gender, BMI, DM, AF, REDO, LVAD thrombosis and the day the thrombosis developed. Conclusion: In conclusion, it is vital to prevent complications that may develop in order to prolong the life expectancy of patients followed up with LVAD. In this study, we have shown that there is no relationship between preoperative right ventricular dysfunction and LVAD thrombosis. It is vital fort his patients group to clarify all the parametres that are likely to be risk factors for LVAD thrombosis with fytyre studies.
