Filter by:The goal of CELL-VAD Pilot trial is to investigate a personalized stem cell therapy approach for patients with advanced non-ischemic chronic heart failure (NICM) who are supported by LVAD. In the clinical trial, the investigators aim to enroll 10 patients with NICM, scheduled for LVAD implantation. After successful LVAD implantation, patients will be enrolled and followed for 2 months to allow for postoperative rehabilitation and heart failure medical therapy and LVAD support optimization. All patients will then undergo autologous CD34+ cell therapy which will be intracoronaryly delivered to the target myocardium using NOGA electromechanical mapping system. All patients will be followed for 6 months after cell therapy. At baseline, and at 1, 3, and 6 months after cell therapy, the investigators will perform comprehensive clinical evaluation.
The aim of this study is to evaluate the incidence of any hemocompatibility related adverse event (HRAE) after LVAD placement in patients responsive to a standard aspirin dose using point-of-care platelet inhibition monitoring compared with initial non-responders who were then up-titrated to achieve a therapeutic response using individualized acetylsalicylic acid (ASA) therapy. Second, to investigate whether patients exhibit temporal changes in ASA sensitivity during LVAD support.
There is a dire need to establish normative values for transcranial Doppler(TCD) derived cerebral blood flow parameters for each type of Mechanical circulatory support (MCS) device and explore the relationship between the MCS device's systemic flow dynamics and TCD based cerebral flow(CBF) parameters TCD derived cerebral blood flow parameters can then be investigated as targets used to titrate systemic flow dynamics from MCS. Having target flow rates titrated to patient specific condition using TCD may help avoid both hypoperfusion as well as the possibility of hyperemia reperfusion injury contributing to neurological morbidity. We propose a multicenter study to gather normative data on TCD derived CBF and MCS systemic dynamics for a wide range of patient demographics. Such data collection is only possible with multi-center collaboration given the small volume of patients with MCS patients in each center.
Investigation of the potential prognostic role of non-invasive myocardial work in patients receiving veno-arterial extracorporeal membrane oxygenation therapy.
This study will be looking at how cardiovascular hemodynamics, including cardiac output and flow through a left ventricular assist device (LVADs), change in response to alterations in preload, afterload, and contractility, and also during exercise, in humans with heart failure who are supported by LVADs.
Left Ventricular Assist Device (LVAD) therapy has become a well-established treatment option for endstage heart-failure either as a bridge to transplant (BTT) or destination therapy (DT). Monitoring of the pump and with this the cardiac status with the HeartMate 3 (HM3) is currently very limited to infrequent log-files with one data entry every 15 minutes and only limited amount of entries. Due to the low resolution data, the standard HM3 monitoring is not feasible for the evaluation of suction events or in depth analysis of the interaction between LVAD and the remaining native heart function. Aim of this study is to develop noninvasive diagnostics of the cardiac remaining respectively recovering function derived from HeartMate 3 pump data only and compare with standard clinical diagnostic procedures. These procedures include cardiac ultrasound and ECG. After this pilot study, the newly developed methods would allow frequent, simple and automatic monitoring of patients implanted with the HeartMate 3 device. Such continuous assessment of cardiac function would massively help therapy optimization of cardiac protection and, if possible, cardiac recovery.
Objective: To explore the experience of transcranial aortic valve replacement (TAVR) under emergency mechanical assisted circulation (MCS).Methods: A total of 6 patients who completed TAVR with the assistance of emergency MCS in the Second Affiliated Hospital of Zhejiang University School of Medicine from March 2013 to June 2019 were retrospectively analyzed.The management of perioperative mechanical assisted circulation, preoperative evaluation, intraoperative operation and postoperative situation of patients were summarized.
The purpose of the Registry is to provide continuing evaluation and periodic reporting of safety and effectiveness of Medtronic market-released products. The Registry data is intended to benefit and support interests of patients, hospitals, clinicians, regulatory bodies, payers, and industry by streamlining the clinical surveillance process and facilitating leading edge performance assessment via the least burdensome approach.
