Long-term outcomes of a novel fully magnetically levitated ventricular assist device for the treatment of advanced heart failure in China. J Heart Lung Transplant 2024:S1053-2498(24)01664-4. [PMID: 38740078 DOI: 10.1016/j.healun.2024.05.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2024] [Revised: 04/28/2024] [Accepted: 05/08/2024] [Indexed: 05/16/2024] Open
Abstract
PURPOSE Left ventricular assist devices (LVADs) are well-established for treating end-stage heart failure, but this therapy is only available to Chinese patients in recent years. The CH-VAD is the first used fully magnetically levitated pump and the most widely used device in China. This study reports the long-term outcomes of a cohort supported by the CH-VAD for the first time. METHODS From June 2017 to August 2023, 50 consecutive patients received CH-VAD implantation in Fuwai Hospital. Clinical data were collected during follow-up and retrospectively analyzed. RESULTS Baseline characteristics included a mean age of 47.9±13.9 years, 90% male, and 26% ischemic etiology. The INTERMACS profile revealed 12% Profile 1, 56% Profile 2, 26% Profile 3 and 6% Profile 4. Mean support duration was 868 ± 630 days (range 33 days-6.4 years). Kaplan-Meier survival rate was 96% (95% confidence interval [CI], 85 to 99) at 6 months, 93% (95% CI, 79-98) at 1 year, 93% (95% CI, 79-98) at 2 years and 89% (95% CI, 71-96) at 3 years. 40 patients (80%) currently remain on support, 3 were bridged to recovery, 2 received transplant, and 5 expired during support. Major adverse events included right heart failure (10%), surgical related bleeding (8%), arrhythmia (8%) and driveline infection (16%). Major hemocompatibility-related adverse events were limited to 3 non-disabling strokes and 1 gastrointestinal bleeding. There was no major device malfunction during the follow-up period. CONCLUSIONS The largest single-center experience with the leading LVAD in China shows high survival with low complication rates, demonstrating the CH-VAD is safe and efficient in providing long-term support for end-stage heart failure patients.

Sci Rep 2024; 14:10291. [PMID: 38704426 PMCID: PMC11069499 DOI: 10.1038/s41598-024-61131-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2023] [Accepted: 05/02/2024] [Indexed: 05/06/2024] Open
Abstract
Kazakhstan has one of the lowest heart transplantation (HTx) rates globally, but there are no studies evaluating the outcomes of HTx. This study aimed to provide a comprehensive analysis of the national HTx program over a 12-year period (2012-2023). Survival analysis of the national HTx cohort was conducted using life tables, Kaplan‒Meier curves, and Cox regression methods. Time series analysis was applied to analyze historical trends in HTx per million population (pmp) and to make future projections until 2030. The number of patients awaiting HTx in Kazakhstan was evaluated with a regional breakdown. The pmp rates of HTx ranged from 0.06 to 1.08, with no discernible increasing trend. Survival analysis revealed a rapid decrease in the first year after HTx, reaching 77.0% at 379 days, with an overall survival rate of 58.1% at the end of the follow-up period. Among the various factors analyzed, recipient blood levels of creatinine and total bilirubin before surgery, as well as the presence of infection or sepsis and the use of ECMO after surgery, were found to be significant contributors to the survival of HTx patients. There is a need for public health action to improve the HTx programme.

Abstract
Heart transplantation is currently the most effective treatment for end-stage heart failure; however, the shortage in donor hearts constrains the undertaking of transplantation. Mechanical circulatory support (MCS) technology has made rapid progress in recent years, providing diverse therapeutic options and alleviating the dilemma of donor heart shortage. The ventricular assist device (VAD), as an important category of MCS, demonstrates promising applications in bridging heart transplantation, destination therapy, and bridge-to-decision. VADs can be categorized as durable VADs (dVADs) and temporary VADs (tVADs), according to the duration of assistance. With the technological advancement and clinical application experience accumulated, VADs have been developed in biocompatible, lightweight, bionic, and intelligent ways. In this review, we summarize the development history of VADs, focusing on the mechanism and application status of dVADs in detail, and further discuss the research progress and use of VADs in China.

Abstract
Approximately 65 million adults globally have heart failure, and the prevalence is expected to increase substantially with ageing populations. Despite advances in pharmacological and device therapy of heart failure, long-term morbidity and mortality remain high. Many patients progress to advanced heart failure and develop persistently severe symptoms. Heart transplantation remains the gold-standard therapy to improve the quality of life, functional status and survival of these patients. However, there is a large imbalance between the supply of organs and the demand for heart transplants. Therefore, expanding the donor pool is essential to reduce mortality while on the waiting list and improve clinical outcomes in this patient population. A shift has occurred to consider the use of organs from donors with hepatitis C virus, HIV or SARS-CoV-2 infection. Other advances in this field have also expanded the donor pool, including opt-out donation policies, organ donation after circulatory death and xenotransplantation. We provide a comprehensive overview of these various novel strategies, provide objective data on their safety and efficacy, and discuss some of the unresolved issues and controversies of each approach.

Abstract
China has the largest number of individuals with congenital heart disease (CHD) in the world and a heavy burden of CHD. Therefore, understanding current CHD treatment outcomes and patterns in China will contribute to global progress in CHD treatment and be a valuable experience. Generally, CHD treatment in China has satisfactory outcomes owing to the joint efforts by all relevant stakeholders across the country. However, efforts are needed to overcome the remaining challenges: management of mitral valve disease and paediatric end-stage heart failure needs to be improved; cohesive paediatric cardiology teams should be established and collaboration between hospitals enhanced; CHD-related medical resources need to be more accessible and equitable; and nationwide CHD databases should be enhanced. In the second paper of this Series, we aim to systematically summarise the current CHD treatment outcomes in China, discuss potential solutions, and provide future perspectives.

Lymph-Node-Targeted Drug Delivery for Effective Immunomodulation to Prolong the Long-Term Survival After Heart Transplantation. ADVANCED MATERIALS (DEERFIELD BEACH, FLA.) 2023; 35:e2207227. [PMID: 36314402 DOI: 10.1002/adma.202207227] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/09/2022] [Indexed: 06/16/2023]
Abstract
The chronic rejection responses and side effects of the systematic administration of immunosuppressants are the main obstacles to heart allograft and patient survival. The development of xenotransplantation also urgently requires more efficient immune regulation strategies. Herein, it is demonstrated that lymph-node (LN)-targeted drug delivery can realize LN-specific immunomodulation with attenuated immune suppression on distant peripheral immune organs to effectively prolong long-term survival after heart transplantation in a chronic murine heart transplantation model. A chemokine C-C motif ligand 21 (CCL21) specific aptamer for LN targeting is decorated onto the surface of the hybrid nanoparticular delivery vector mainly composed of CaCO3 /CaP/heparin. The targeting delivery system can dramatically enhance accumulation of the loaded immunosuppressant, fingolimod hydrochloride (FTY720), in draining lymph nodes (dLNs) for inducing powerful immune suppression. By promoting the generation of endogenous regulatory T cells (Tregs ) and decreasing the proportion of effector T cells (Teffs ) in dLNs after heart transplantation, the LN-targeting strategy can effectively regulate local immune responses instead of systemic immunity, which reduces the incidence of long-term complications. This study provides an efficient strategy to improve the survival rate after organ transplantation by precise and localized immunoregulation with minimized side effects of immunosuppression.
