Highlights. The level of professional competence of medical staff is important in rehabilitation of patients with cardiovascular diseases. It is important to build nurses' skills at all stages of professional development. The mentoring institute itself is integral to this process, as it ensures knowledge continuity and transfer of experience and best practices from more experienced staff to less experienced ones.Aim. To analyze existing mentoring practices.Methods. Using analytical method, content analysis and system analysis, we have analyzed domestic and foreign literature, as well as relevant regulatory and legal documentation for the period from 2017 to 2022.Results. The objectives of mentoring programs implemented in the practice of domestic and foreign healthcare organizations were analyzed. Existing approaches to its implementation in relation to the role of the mentoring institution in the formation and development of professional skills of nursing staff were evaluated.Conclusion. The analysis revealed a variety of approaches to the implementation of the mentoring programs for nursing staff. The study results highlight the significant role of mentoring in the formation of professional skills. It is proved that at each stage of mentoring process it is possible to gain knowledge and various skills necessary for medical staff to perform their duties independently.

Background: Parameters of longitudinal systolic function, i.e. tricuspid annular plane systolic excursion (TAPSE) and peak systolic velocity (PSV) of tricuspid annulus are used to quantify RV function in daily practice. Changes in TAPSE and PSV after cardiac surgery have been described for many years but data regarding the mechanism of these changes are conflicting and their clinical significance is unexplored. Purpose: We investigated the natural course and long-term prognostic impact of changes in RV longitudinal function parameters after aortic valve replacement (AVR) in a large cohort to determine their clinical relevance. Methods: Between January, 2009 and December, 2015, we prospectively explored all consecutive patients referred to our cardiovascular surgery department for AVR presenting with severe aortic stenosis (AS), normal left ventricular ejection fraction (>40%) and TAPSE (>14mm). TAPSE and PSV were assessed with transthoracic echocardiography (TTE) 7 days after cardiac surgery for all patients and one year after AVR in a subgroup of 100 patients. Patients were followed for major cardiac and cerebral events (MACCE). Results: Among a total of 752 patients, 135 patients presented poor acoustic window precluding reliable post-operative measurement of RV parameters. 617 patients were followed for post-operative MACCE. TAPSE and PSV were severely decreased after surgery (p<0.0001) with a significant but incomplete recovery to the pre-operative values one year after AVR. Longer cardio-pulmonary bypass duration was the only independent parameter associated with more important decrease in RV parameters after AVR. After a mean follow-up of 4±2.3 years, no association was shown between post-operative alterations in RV longitudinal function parameters and long-term prognosis: p-value=0.14 by log-rank test for MACCE, p=0.6 for cardiac hospitalization and p=0.16 for acute heart failure. Survival probability free-from MACCE Conclusion: Post-operative changes in RV longitudinal function parameters have no clinical relevance to predict long term outcome after AVR surgery and should not be used as surrogate of global RV function in those patients. Background: The symptom burden in atrial fibrillation (AF) can be disabling for patients (pts) prior to ablation. Symptoms pre-ablation have been found to be unrelated to underlying AF. It is unclear if this is true during the first 3-6 months (mths) after an AF ablation. Purpose: To evaluate the correlation of pt perceived symptoms to underlying heart rhythm using Zio ® Patch heart rhythm monitors during the initial 6-month recovery period following an AF ablation. Methods: We conducted a 2-year longitudinal, pilot study with data collection points at baseline (pre-ablation) and at 1, 3, and 6 mths following AF ablation treatment in 20 pts with paroxysmal or persistent AF. Symptoms were measured by the Patient Perspective of Arrhythmia Questionnaire (PPAQ). Pts were asked to wear a Zio ® Patch adhesive, wireless, cardiac monitor for 14 days at each time point and press t...
