A Hybrid Procedure Combining Mini-Thoracotomy with Interventional Endocardial Lead Implantation for Cardiac Resynchronization Therapy in Patients with Chronic Congestive Heart Failure: A Report of Four Cases

Background: We describe the use and success of transthoracic electrode implantation in epicardial left ventricular pacing in cardiac resynchronization therapy for patients with persistent congestive heart disease. We analyzed four patients with persistent congestive heart disease in whom endocardial electrode placement was forbidden. In all four patients, the epicardial electrodes were successfully implanted. None of the patients had electrode fractures or surgical wound infections, and electrode impedance and pacing threshold were normal. Phrenic nerve stimulation was triggered in one instance due to the electrode's poor placement position. When the electrode was moved slightly inward and upward, the sacral nerve stimulation sign disappeared, and no other problems were found. The implantation of a left ventricular epicardial electrode via a left-sided small incision in CRT is safe, simple, and cost-effective.

Galectin-3 levels and the prediction of atrial high-rate episodes in patients with cardiac resynchronization therapy

In the long-term follow-up of cardiac synchronization therapy patients, the present study sought to determine the connection between the presence of AHRE and the coronary sinus serum testing of galectin-3 levels. A total of 108 consecutive CRT patients were enrolled prospectively in the study. Samples were collected from the CS blood collection catheter to perform galectin-3 measurements. Patients with AHRE were significantly higher than those without AHRE, with a corresponding increase in CS galectin-3 levels. In addition, CS galectin-3 results had a strong positive correlation with percent of time invested in total AHRE. Left atrium volume and CS galectin-3 levels, according to a multivariate logistic regression study, were significant and independent predictors of AHRE. In this research, we discovered that elevated CS galectin-3 levels in CRT patients was a predictor of AHRE development in CRT patients.

Role of cardiac resynchronization therapy in the development of new-onset atrial fibrillation: A single-center prospective study.

Abstract Albeit many studies investigated the relationship between heart resynchronization therapy and atrial fibrillation in heart failure, but the results are still unclear and highly conflicting. We'll also determine whether CRT has a positive influence on the incidence of new-onset AF in a homogeneous group of patients with non-ischemic dilated cardiomyopathy and extreme heart failure HF in a homogeneous population of patients with non-ischemic dilated cardiomyopathy and severe heart failure HF. Already after 1 year, there is a significant difference in new-onset AF in non-responder patients' respect to responders.

Cardiac Resynchronization Therapy: Prospect for Long-Lasting Heart Failure Remission

Heart disease remains a significant heath care issue in the United States. Heart resynchronization therapy has emerged as a more effective treatment option for treating heart failure due to systolic dysfunction. We also look at important scientific aspects of CRT that are still under study, including predictors of response. Finally, we take a look at the future of CRT and how its indications can be extended to benefit more patients in the future.

Impact of long-term optimizing atrioventricular delay using device-based algorithms on cardiac resynchronization therapy

A total of 118 patients who underwent CRT at our hospital between April 2008 and March 2018, were retrospectively reviewed; 61 of them with optimizing AVD using DBAs were included in the treated group; the remaining 57 were classified into the control group; the remaining 57 were classified into the control group. The response and survival rate in group 1 were much higher than those in group 2 despite group 2's similarity. In addition, only the non-responder group found that group 1 had a higher survival rate than group 2 compared to group 2.

Cardiac resynchronization therapy outcomes in patients with chronic heart failure and comorbidity

Chronic heart disease is the most common medical disorder. We offer our current viewpoint on the safety of CRT use in patients with CHF and multimorbidity burden in this report.

Interaction between secondary mitral regurgitation and left atrial function and their prognostic implications after cardiac resynchronization therapy

Abstract Aims Left atrial function is a key diagnostic marker in patients with heart disease and functional mitral regurgitation. Though cardiac resynchronization therapy has been shown to reduce MR severity and an rise in LA function, as well as its relationship with outcomes, has not been investigated. Methods and findings Methods and findings Anthropolous tracking echocardiography in patients with at least moderate functional MR undergoing CRT implantation was used in a literature review. At least 1 grade improvement in MR severity was identified as at least 1 grade improvement in MR severity at 6 months after CRT implantation. At a 6 months follow-up, a total of 340 patients was included, of whom 200 had MR improvement. The lowest mortality risk among MR non-improvers and MR improvers with LARS increasement was found, but not significantly different between MR non-improvers and MR improvers with no LARS increasement.

Comparative efficacy of image-guided techniques in cardiac resynchronization therapy: a meta-analysis

Abstract Background Several studies have shown that echocardiography, magnetic resonance imaging, and nuclear imaging can all be used to optimize left ventricular lead placement to improve heart failure therapy in heart failure patients. The LV lead to the latest sites of contraction, heart failure hospitalization, mortality risks, increases of left ventricular ejection fraction, and left ventricular end-systolic volume were among the final results. Conclusions The study population included 1075 patients from eight studies. The LVESV reduction in the image-guided group was much higher than that in the control group. No significant difference was found between two groups in HF hospitalization and mortality rates. Conclusions This meta-analysis shows that image-guided CRT is correlated with increased CRT volumetric response and cardiac function in heart failure patients with improved CRT volumetric response and cardiac function, but not with lower hospitalization or mortality rates.

Electro-echocardiographic Indices to Predict Cardiac Resynchronization Therapy Non-response on Non-ischemic Cardiomyopathy

Heart failure therapy was discussed in the light of heart disease therapy, but some of patients's responses to CRT were nonresponsive to CRT. This is a retrospective review of a total of 227 patients of dyssynchronous heart failure who underwent CRT implantation. CRT responders and CRT non-responders were compared in a logistic analysis. The primary result was a revival of improved left ventricular ejection fractions, which occurred 1 year after CRT implantation.
