Filter by:This is a prospective multi-center international registry. The objective of this registry is to collect prospective data on patients undergoing catheter ablation for Ventricular Tachycardia (VT) and Premature Ventricular Contractions (PVC). The registry will be used for clinical monitoring, research, and quality improvement purposes.
This is a monocentric, prospective, single arm, not for profit study. It is designed to study the early use of ivabradine in patients with dilated cardiomyopathy and Ejection Fraction (EF) < 45%.
The Hearts in Rhythm Organization (HiRO) is a national network of Canadian researchers/clinicians, working towards a better understanding of the rare genetic causes of sudden cardiac death (SCD). Canadian adult and pediatric electrophysiology centres across Canada work together to gather data and bio sample in a national data registry and bio bank hoping to improve the detection and treatment of inherited heart rhythm disorders to prevent sudden death.
This is a follow up investigation to our previous study entitled "On-pump intraoperative echocardiography (OPIE)" (clinicaltrials.gov NCT03094325) whereby we determined that left ventricular septal thickness as measured by the OPIE technique correlates highly with traditional methods of transthoracic and transesophageal echocardiography during septal myectomy for hypertrophic cardiomyopathy. OPIE may be especially useful in patients with a thin ventricular septal thickness as adequate treatment may rely on mere millimeters of myocardial resection. We therefore propose a study in which OPIE is compared to transthoracic and transesophageal echocardiography in patients with a thin interventricular septum. Subjects will receive the same perioperative care regardless of their involvement in the study. Patients who enroll in the study will undergo an additional intraoperative echocardiographic measurement that adds less than five minutes to total operative time.
This is a joint project by Sahlgrenska University Hospital: Sahlgrenska, Östra and Mölndal. Our objective is to diagnose and map patients with well phenotyped cardiomyopathies (CMP) including in depth clinical and molecular phenotyping to enable earlier and specific treatment. The project will serve as: 1. resource for diagnostic and therapeutic trials 2. common biomaterial bank 3. resource for detailed molecular analyses on patients' biomaterials and patient specific symptoms and examination results
Fluoroscopy guided EMB and EAM guided EMB on all patients meeting existing guidelines for biopsy.
Various factors affect the performance of the heart: The contractile properties of myocardial muscle cells are the fundamental devices for translating tension-generation and shortening of the cardiac muscle into pressure-generation and blood volume ejection from the heart into the body. On the other hand, the performance of heart can be analyzed with respect to input and output of blood to/from the hollow cardiac muscle and evaluated in terms of the performance of a pump: With every heartbeat blood is sucked from a low-pressure system (veins) and pumped to the arterial high-pressure system via one-way valves, whereas efficiency, ejected blood volume, blood flow and pressures are linked by hemodynamic laws. Cardiac magnetic resonance (CMR) is the "gold standard technique" to determine cardiac function and muscle mass, as well as for non-invasive diagnosis of myocardial necrosis/fibrosis. Furthermore, new CMR imaging techniques enabling the measurement of myocardial magnetic relaxation times for characterization of myocardial morphology and the acquisition of time-resolved, three-dimensional blood flow velocity fields in the heart and surrounding vessels, represent promising tools for the evaluation of the interaction between myocardial morphology and cardiac function. Aim of this explorative study is to 1. identify myocardial pathology-associated blood flow patterns in the heart and surrounding great vessels, and 2. correlate characteristic blood flow patterns in the heat (existence of vortices, vorticity, vortex formation, propagation dynamics …) with myocardial injuries.
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.
It has been known that liraglutide reduces infarct size, improved left ventricular function, reduce myocardial stunning, and play a protective role in myocardial ischemia-reperfusion injury for patients with acute myocardial infarction. But it is not sure whether liraglutide can benefit patients with ischemic cardiomyopathy. This study aim to explore the effect of Liraglutide in improving cardiac function for patients with ischemic cardiomyopathy.
Dilated cardiomyopathy (DCM) is characterized by a metabolic shift from fat to carbohydrates and failure to increase myocardial glucose uptake in response to workload increments. The investigators aimed at verifying whether this pattern is influenced by the presence of abnormal glucose tolerance (AGT).
