Predictors of worsening TR severity after right ventricular lead placement: any added value by post-procedural fluoroscopy versus three -dimensional echocardiography?

BACKGROUND: The effect of right ventricular (RV) leads on tricuspid valve has been already raised concerns, especially in terms of prognostic implication. For such assessment, three-dimensional transthoracic echocardiography (3D-TTE) has been used previously but there was no data on the use of post-procedural fluoroscopy in the literature. METHODS: We prospectively enrolled 59 patients who underwent clinically indicated placement of pacemaker or implantable cardioverter defibrillator (ICD). Vena contracta (VC) and tricuspid regurgitation (TR) severity were measured using two-dimensional transthoracic echocardiography (2D-TTE) at baseline. Follow up 3D-TTE was performed 6 months after device implantation to assess TR severity and RV lead location. RESULTS: Lead placement position in TV was defined in 51 cases.TR VC was increased after the lead placement, compared to the baseline study (VC: 3.86 ± 2.32 vs 3.18 ± 2.39; p = 0.005), with one grade worsening in TR in 25.4% of cases. The mean changes in VC levels were 1.14 ± 0.67 mm. Among all investigated parameters, VC changes were predicted based on lead placement position only in 3D-TTE (p < 0.001) while the other variables including fluoroscopy parameters were not informative. CONCLUSION: The RV Lead location examined by 3D-TTE seems to be a valuable parameter to predict the changes in the severity of the tricuspid regurgitation. Fluoroscopy findings did not improve the predictive performance, at least in short term follow up.

Effective Strategies for Physical Activity Adherence in Heart Failure Patients: An Umbrella Review.

Background: Despite the importance of physical activity in heart failure treatment, physical activity adherence in heart failure patients is low. The purpose of this umbrella review was to obtain the best strategies for enhancing physical activity adherence among HF patients. Methods: Databases were investigated from 2010 to Jan 2022. The full text of the papers was investigated in terms of inclusion and exclusion criteria. Eventually, out of 74 relevant papers, 7-review study with 20977 patients were eligible and included in the study. Results: Five key effective approaches were identified in two subsets for enhancing physical activity adherence as follows: 1) exercise-based approaches including 1.1) Exergames, whereby the extent of adherence to exergames was between 84 and 98%. 1.2) Tele-rehabilitation with 70%-100% adherence the intervention groups 1.3) Tai chi and Qigong practices (TQPs), whereby the exercise adherence in TQP groups was 67-100%, 2. Theoretical-behavioral approaches 2.1) approaches based on behavioral and psychological theories, which were a combination of an exercise program alongside a behavior modification intervention, 2.2) Self-efficacy. Conclusion: Approaches that are based on exercise alongside behavioral and theoretical interventions could enhance physical activity adherence among HF patients. It is suggested to evaluate mix methods of exercise-based approaches and theoretical-behavioral approaches mentioned in this study in future clinical trial studies. Use of capacity of TR programs improve to physical activity adherence should receive more attention.
