Filter by:The investigators are interested in determining the best surgical technique to correct functional mitral regurgitation, as there is currently not one technique that is established to work better than the other. The technique used in current clinical practice is undersizing mitral annuloplasty (UMA), in which a prosthetic ring is implanted onto the mitral valve to correct the leakage. Though widely adopted, durability of the repair is less, as 58% of the patients present with recurrent FMR within 2 years. There are no specific algorithms to predict who might have UMA failure, but research indicates that some geometric indices might be strong predictors. The investigators are interested in testing the hypothesis that, elevated lateral inter-papillary muscle separation (IPMS) is a predictor of post-UMA recurrence of FMR at 12 months. In the first part of this study, the study team will measure lateral IPMS before surgery, and relate to post-surgery FMR severity at discharge/30 days, 6 months and 12 months. A relatively newer technique is papillary muscle approximation (PMA), in which a suture draws together the two muscles that connect the mitral valve to the heart muscle prior to performing UMA. This reduces the lateral inter-papillary muscle separation (IPMS) and is expected to improve the durability of UMA. In the second part of this study, the investigators will perform PMA and UMA together and determine if FMR severity is reduced at discharge/30 days, 6 months and 12 months.
This study assesses the value of arrhythmogenic substrate identification and elimination by catheter ablation to prevent recurrent ventricular arrhythmias and sudden cardiac death in a series of selected patients with primary cardiomyopathy and/or channellopaties with ICD implantation.
This project is designed to demonstrate equivalence of Dotarem enhanced LGE-CMR (late gadolinium enhancement cardiac MRI) with Gadoviost enhanced LGE-CMR from the standpoint of visual image quality, quantitative image quality, and association with clinical outcomes.
This randomized pilot phase I trial studies the side effects of donor bone marrow derived mesenchymal stem cells in controlling heart failure in patients with cardiomyopathy caused by anthracyclines. Donor bone marrow derived mesenchymal stem cells may help to control symptoms of heart failure and improve heart function.
Phase I/II Study of EP-guided Noninvasive Cardiac Radioablation (ENCORE) for Treatment of Ventricular Tachycardia
Population study- patients with obstructive hypertrophic cardiomyopathy that are treated with disopyramide. Tow echo examination, few hours apart, that includes strain rate will be done to each patient. The first, after taking the regular medical treatment excluding disopyramide and the last one after taking the disopyramide.
There may be a relationship between heart function and the metal ion levels in patients having undergone total hip replacement. The idea is to use results from a clinical cardiac MRI to assess heart function in a sample of 30 patients whom have undergone either metal-on-metal hip replacement (unilateral or bilateral) or a non-metal on metal total hip replacement to determine whether having undergone a metal on metal hip procedure may be impacting heart function. In addition to the clinically used parameters, the images will also be retrospectively assessed using special software to assess amount of fibrosis and early changes affecting cardiac muscle contraction which may be indicative of impaired heart function. With these values we will compare to known, and previously collected, hip replacement and function data to determine whether there is any differences in how the heart works in those having had a hip replacement relative to a normal population.
The aim of this project is to identify common genetic polymorphisms associated with the occurrence of rhythmic events in patients with severe cardiomyopathy.
The purpose of this study is to explore how the End Tidal Carbon Dioxide monitoring via nasal cannula (ETCO2-NC) device may allow for earlier detection of respiratory complications. This device will detect the amount of carbon dioxide exhaled with each breath and may better predict high levels of this than traditional monitoring. This may reduce the number and severity of respiratory issues. A convenience sample of 60 participants either scheduled for continuous flow left ventricular assist device (CF-LVAD) implant or who have been readmitted to an ICU with a CF-LVAD will be recruited and randomized to usual care or usual care plus ETCO2-NC throughout their stay in the ICU.
The purpose of this exploratory developmental study is to test the feasibility, acceptability, and preliminary efficacy of cognitive behavioral therapy for insomnia (CBT-I) among adults who have stable Heart Failure. Participants were randomized either to a treatment (CBT-I) or attention-control condition (heart failure self management education).
