Brief summary
The purpose of this study is to examine the validation of the PiCCO (Pulse Contour Cardiac Output)-derived transpulmonary thermodilution technology in patients with heart diseases.
Detailed description
* How do PiCCO and PAC (pulmonary artery catheter) derived hemodynamic variables change in different cardiac pathologies? * How do PiCCO hemodynamic variables compare to transthoracic echocardiographic parameters in different cardiac pathologies? * How does GEDV (global enddiastolic volume) correlate with left ventricles end-diastolic volume (LVEDV) assessed by LV (left ventricle) ventriculography and echocardiography? * How do PiCCO cardiac function variables (GEF \[global ejection fraction\]; CFI \[cardiac function index\]) correlate with LV dP/dt max, LVEF (left ventricular ejection fraction) assessed by LV ventriculography and echocardiography, LVFAC (left ventricular fractional area of change), LV stroke work index (LVSWI) and cardiac power (CP)? * How does GEDV compare to LVEDV and left ventricular end-diastolic pressure (LVEDP) as assessed by the pulmonary artery occlusion pressure (PAOP)? * How does right ventricular function influence GEDV, GEF and CFI?

Inclusion criteria
* Coronary heart disease without impaired left ventricular function \[LV-EF \> 50%\] (n=10, control group) * Coronary heart disease with impaired left ventricular function \[LV-EF \< 50%\] (n=10) * Dilated cardiomyopathy (n=10), * Aortic valve stenosis (n=10), * Mitral valve regurgitation (n=10), * Diastolic left ventricular dysfunction (n=10) and * Right heart failure (n=10)
Exclusion criteria
* Patients with catecholamine dependent cardiogenic shock, severe respiratory distress because of pulmonary oedema, intubated patients, patients with atrial fibrillation, atrioventricular conduction abnormalities, and slow ventricular tachycardia will not be included. * Moreover patients not being able to give informed consent are excluded. Even more, pregnant women are excluded from the study due to the radiation exposure in line with heart catheterization. A pregnancy test will be performed prior to participating with this study. * The age does not represent an exclusion criterion.
Design outcomes

| Measure | Time frame | Description |
|---|---|---|
| Cardiac Output, Preload values (GEDV) | Day 1 only | Outcome measure is obtained during PiCCO measurement and left/right heart catherization, respectively (point-of-care measurement). There is no follow-up examination thereafter. |
