Brief summary
There is preliminary evidence that a dynamic T2 Preparations Puls sequence by cardiac magnet resonance imaging can differentiate between oxygenated and deoxygenated blood. In adult patients with inborn heart defects this has not yet been researched. Therefore,patients with ventriculoperitoneal shunt, septal and atrio-septal shunt should be examined. Also, patients with chronic obstructive pulmonary disease should be examined. The aim of this study is the validation of a novel magnet resonance sequence in terms of a distinction of oxygenated blood to deoxygenated blood in comparison to invasive method of measuring cardiac catheterization.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| ventricular volumetry | baseline | ventricular volumetry by Cardiac Magnet Resonance Imaging using dynamic T2 Preparation Puls for arithmetical determination of end-systolic volume, end-diastolic volume, ejection fraction, stroke volume and myocardial weight |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| oxygen partial pressure | baseline | Determination of oxygen partial pressure (pO2) during angiography |
| carbon dioxide partial pressure | baseline | Determination of carbon dioxide partial pressure (pCO2) during angiography |
| pH-value | baseline | Determination of pH-value od blood during angiography |
| Blood gas analysis | baseline | Determination of base excess of blood during angiography |
| Major adverse cardiac events | 12 month after procedure | Major adverse cardiac events: death, new indication for angiography, hospitalization |
