According to the high morbidity and mortality of idiopathic Dilated CardioMyopathy (IDCM) in pediatric, new modality of treatment is emerging. There are some case reports of administration of stem cell therapy. The investigators design the first randomized clinical trial in this setting. The investigators enroll 32 pediatric IDCM patients in two groups (16 pts. in each group including cell therapy and control). The investigators assess the safety and efficacy of intracoronary transplantation of autologous bone marrow derived mononuclear cells in this patients compared to control group.
The purpose of this study is to determine clinical outcomes related to deactivation of Cardiac Resynchronization Therapy device in subjects with super response.
The objective of this extension study is to evaluate the safety and potential beneficial effects of the Algisyl-LVR™ device in patients with established heart failure secondary to a dilated cardiomyopathy. The results of this study will provide confirmatory evidence of the long-term safety and effectiveness of the Algisyl-LVR in patients with established heart failure.
This is a prospective clinical trial to determine the optimal QLV interval during implantation to achieve the best possible response from cardiac resynchronization therapy for heart failure patients.
The purpose of this trial or study is to determine if cardiac resynchronization therapy (CRT) can be a benefit to people who have impaired heart function due to past treatment with chemotherapy and/or chest radiation. The investigators are looking to enroll approximately 30 eligible subjects with heart failure in this trial. All patients enrolled and registered in the study will be implanted with a cardiac resynchronization therapy device that includes an implantable cardiac defibrillator (CRT-D). Clinical histories, physical exams, and external device testing will be collected both at the time of enrollment in the trial and during follow-up study visits. Following implantation of the CRT-D, patients will be contacted by phone at 3 months and will have a scheduled clinic visit follow-up at 6 months.
The purpose of this study is to determine whether remote ischemic preconditioning with postconditioning (RIPC+RIPostC) reduces myocardial injury and improves clinical outcomes in heart transplantation surgery.
The overall aim of this trial is to study the safety and efficacy of ICD implantation as a primary prevention strategy of sudden cardiac death in patients 70 years and older. This study will assess the many competing factors involved with ICD implantation including 1) the impact on mortality, especially in the context of a declining rate of sudden death with advanced age, 2) the tolerability of the powerful therapeutic action of the device, and 3) the impact on quality of life.
The objective of this study is to evaluate myocardial injury, if any, as quantified by cardiac markers (Troponin-T) in defibrillation threshold (DFT) testing during implantation of implantable cardioverter defibrillators (ICDs) using the upper limit of vulnerability (ULV) method vs. standard defibrillation threshold method.
If a surgical sponge is mistakenly left inside a patient's body after a surgical procedure, it can cause a serious infection. To prevent this from happening, a new device has been developed that uses radiofrequency (RF) signals to detect the presence of surgical sponges inside the body. The device is now being used routinely to make sure that no sponges are left inside a patient at the end of an operation. However, the RF device has not been implemented in procedures for patients with cardiac implantable electronic devices (CIEDs). While the device is FDA approved for use, there is a theoretical concern that the radiofrequency signals used to detect the sponges will change the settings on the pacemaker or the defibrillator. Changing the settings on a pacemaker might make it pace the heart too quickly or too slowly, while changing the settings on a defibrillator might cause unnecessary shocks or prevent it from shocking the heart if the patient were to have cardiac arrest. The purpose of this study is to test whether the radiofrequency device used to detect sponges can cause a clinically significant change to the settings on pacemakers and defibrillators. To minimize potential risk, the device will be tested only on patients who are having the pacemaker or defibrillator removed or replaced as part of their regular medical care, either because it is infected or because the battery has worn out. Before the pacemaker or defibrillator is removed, the settings will be carefully and completely recorded and the radiofrequency device will be used to scan the body for sponges as it would be done during normal operation. After the pacemaker or defibrillator is taken out, the settings will again be recorded and compared to the settings before the scan. In a standard device removal procedure, no clinically significant change in CIED settings would be expected. If a new pacemaker or defibrillator is implanted in the patient, it will not be exposed to the detection device at all. We will also test whether the RF device has any effect on temporary pacemakers that patients may receive after open heart surgery. We plan to perform testing in a total of 50 patients, 40 with permanent pacemakers or defibrillators and 10 with temporary pacemakers.
