To evaluate short-term and long-term effects by MR imaging at 3T on the technical and functional status of cardiac pacemakers.
Recently, a shift could be observed from cardiac pacemakers being an absolute contraindication to being a relative contraindication for MR imaging at 1.5 Tesla, depending on a patient-per-patient risk-benefit-evaluation, which includes an urgent clinical need for MR imaging (other imaging modalities non-conclusive) and co-morbidities (especially cardiac co-morbidities). At the same time, MR imaging at 3 Tesla is evolving from a research application only to an important imaging modality today.
Using the improved signal-to-noise-ratio, high field MR-Systems with a field strength of 3 Tesla offer a variety of diagnostic advantages to 1.5 Tesla systems. These advantages lead to a higher sensitivity and specificity in diagnosing, foremost neurological, disorders.
In this study, we evaluate the safety of MR imaging of the brain in patients with cardiac pacemakers at 3T.

The objective of the study is to investigate congenital disorders of glycosylation in congenital heart diseases without a clear molecular or genetic basis.
Congenital heart disease is one of the most common malformations in newborns. About 1% of newborns have cardiac malformations. Many need open heart surgery, which contributes substantial...

Previously, our group reported that lymphotropic hepatitis C virus (HCV) could induce various kinds of immune-dysfunctions. The immune-dysfunctions could cause vascular disease by inducing cryoglobuli...

Congenital heart diseases are the most common type of congenital defects, and account for more deaths in the first year of life than any other condition, when infectious etiologies are ruled out.

Occlusion of the outflow tract in either the LEFT VENTRICLE or the RIGHT VENTRICLE of the heart. This may result from CONGENITAL HEART DEFECTS, predisposing heart diseases, complications of surgery, or HEART NEOPLASMS.
Diseases characterized by pathological irregularities in the HEART CONDUCTION SYSTEM. They may be associated with other heart diseases and syndromes (e.g., BRUGADA SYNDROME; NEUROMUSCULAR DISEASE, HEART BLOCKS), isolated or may result from injuries. You can have a conduction disorder without having an arrhythmia, but some arrhythmias arise from conduction disorders. OMIM: 601144.
Diseases of long duration and generally slow progression. The four main types of noncommunicable diseases are CARDIOVASCULAR DISEASES (e.g., heart attacks and stroke), CANCER, chronic respiratory diseases (e.g., CHRONIC OBSTRUCTIVE PULMONARY DISEASE and ASTHMA) and DIABETES MELLITUS.
Pathological conditions involving the HEART including its structural and functional abnormalities.
