Adaptive CRT Effect on Electrical Dyssynchrony
CardiomyopathyHeart Failure1 moreThe purpose of this study is to better understand how adaptive cardiac resynchronization therapy (aCRT) might benefit patients. aCRT works by sometimes giving stimulation to only the left side of the heart, rather than to both sides, depending on how it senses the heart is functioning. CRT without the adaptive algorithm works by giving stimulation to both sides of the heart. aCRT has already been approved by the FDA and is being used in patients now, but it is not clear which patients it should be used in compared to normal CRT. This study will include patients who are already scheduled to get a CRT device. The investigators will then randomize patients to the aCRT study arm or to the CRT study arm. After 6 months, the investigators will assess the electrical activity of the patients' hearts. After this time, the patient and their doctors will be able to decide if they would like to change the type CRT they have been designated.
Surgical Treatment of Hypertrophic Obstructive Cardiomyopathy With Severe Mitral Insufficiency....
Hypertrophic Obstructive CardiomyopathyCompare the results of reconstruction and mitral valve replacement in the surgical treatment of obstructive hypertrophic cardiomyopathy with severe mitral insufficiency.
Bone Marrow Derived Adult Stem Cells for Dilated Cardiomyopathy
Dilated CardiomyopathyA randomised, double-blind, placebo-controlled trial to evaluate the role of intracoronary injection of progenitor cells compared to placebo injection in patients with Dilated Cardiomyopathy who have been pre-treated with G-CSF (Granocyte™) injections for 5 days, and patients treated with a 5 day course of G-CSF (Granocyte™) injection only compared to placebo injection
A Study of Genetically Targeted Enzyme Replacement Therapy for Advanced Heart Failure
Ischemic CardiomyopathyNon-ischemic Cardiomyopathy2 moreThe purpose of this trial is to assess whether MYDICAR can reduce the frequency and/or delay heart failure related hospitalizations in persons with advanced heart failure when added to their maximal and optimized therapy.
Edema and Fibrosis CMR Imaging in Cardiomyopathy
Cardiomyopathies7 Tesla MRI is a new magnetic field strength that has become available at Penn for cardiovascular MRI. This new scanner has potential to improve assessment of cardiovascular disease due to its increased signal-to-noise ratio, higher spatial resolution, and response to magnetic properties of tissue at high field. The purpose of this study is to assess the feasibility of 7 T CMR. Secondly, we wish to investigate its use, to improve clinical and research MRI. Altogether, 7 T may permit better clinical diagnosis of cardiomyopathy.
Study of Efficacy and Safety of Percutaneous Coronary Intervention to Improve Survival in Heart...
Ischemic CardiomyopathyThis study will assess whether percutaneous coronary intervention (angioplasty of the heart arteries) can improve survival and reduce hospitalization in patients with heart failure due to coronary disease, who have been treated with the best contemporary medical therapy.
Analysis of Both Sex and Device Specific Factors on Outcomes in Patients With Non-Ischemic Cardiomyopathy...
CardiomyopathiesGender1 moreThe purpose of this registry is to prospectively assess outcomes of device-treated ventricular tachyarrhythmias and all-cause mortality in non-ischemic cardiomyopathy patients indicated for ICD or CRT-D implantation for the primary prevention of sudden cardiac death. Differences in outcomes will be evaluated by sex and by device type.
OptiVol for Precision Medical Management of Heart Failure
Ischemic and Non-ischemic CardiomyopathyThis clinical study is designed to show that a multidisciplinary team following a pre-specified standard of care medication decision model based on data from an implanted cardioverter device will increase the rate of change in Guideline Directed Medical Therapy (GDMT) in the intervention group compared to the conventional group in patients with ischemic and non-ischemic cardiomyopathies.
Randomized Comparison of Endocardial Versus Epicardial - From the Coronary Sinus - Left Ventricular...
Heart FailureCardiomyopathy2 moreBiventricular pacing is a validated treatment for patients suffering from heart failure resistant to medical treatment. However, up to 30% of the patients are non responsive to this strategy using the coronary sinus approach to pace the Left Ventricle (LV). It has been demonstrated that the magnitude of the improvement was highly dependant on the LV pacing site. The coronary sinus approach rarely offers more than 1 or 2 potential pacing sites. Resynchronisation using a transeptal approach to pace the left ventricle on the cardiology has been shown feasible on small series. We therefore would like to compare these two approached in a randomised prospective study to confirm the hypotheses that endocardial LV pacing by offering multiple choices for the pacing sites reduces the number of non responders and is associated with greater hemodynamic benefit when compared to the conventional coronary sinus approach.
ACC - Atrial Contribution to CRT
Dilated CardiomyopathyThis prospective study will evaluate in patients, fulfilling implant criteria for Cardiac Resynchronisation Therapy (CRT) implant, the optimal atrial contribution to the resynchronised ventricles in the event of right atrial pacing.
