The purpose of this study is to evaluate long-term performance of the 4196 LV Lead. This evaluation is based on the number of lead-related complications occurring during the study compared...
Heart failure is a progressive disease that decreases the pumping action of the heart. This may cause a backup of fluid in the heart and may result in heart beat changes. When there are ch...
The purpose of the study is to assess lead implant success and complication rate using the Medtronic Attain Family of left-heart leads and delivery catheters.
This study is designed to show that a new lead, which paces the left bottom chamber (left ventricle) of the heart, is safe. Using a lead on the left side of the heart has been shown to pot...
The purpose of the Optimize RV study is to determine the long-term effect of selective site pacing. Selective site pacing refers to which area of the right ventricle the lead is placed. T...
The relevance of gene mutations leading to heart diseases and hence heart failure has become evident. The risk for and the course of heart failure depends on genomic variants and mutations underlying ...
Barriers in heart failure self-care contribute to heart failure hospitalizations, but geographic differences have not been well-studied. We aimed to compare self-care barriers in heart failure patient...
Recognizing the rising prevalence of heart failure in China, patients with heart failure have substantial palliative needs. This review highlights recent evidence on the epidemic of heart failure, ide...
Heart failure is an increasing reason for hospitalization and the leading cause of death in patients with adult congenital heart disease (ACHD). Recently, the European Society of Cardiology and the Am...
A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.
Enlargement of the HEART, usually indicated by a cardiothoracic ratio above 0.50. Heart enlargement may involve the right, the left, or both HEART VENTRICLES or HEART ATRIA. Cardiomegaly is a nonspecific symptom seen in patients with chronic systolic heart failure (HEART FAILURE) or several forms of CARDIOMYOPATHIES.
Heart failure caused by abnormal myocardial relaxation during DIASTOLE leading to defective cardiac filling.
Heart failure caused by abnormal myocardial contraction during SYSTOLE leading to defective cardiac emptying.
Congenital arteriovenous malformation involving the VEIN OF GALEN, a large deep vein at the base of the brain. The rush of arterial blood directly into the vein of Galen, without passing through the CAPILLARIES, can overwhelm the heart and lead to CONGESTIVE HEART FAILURE.
