Angina Pectoris Clinical Trial
Official title:
Hybrid Intraprocedural Imaging From 2D-Strain-echocardiography and X-ray Based Biplane Coronary Angiography for Guiding Interventional Revascularization Therapy
The investigators will check the feasibility of an intraprocedural vitality diagnostics and the identification of an indication for Percutaneous transluminal coronary angioplasty (PTCA).

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Cut-Off-Value of vital myocardial tissue | It will be determine cutt-off-value of vital myocardial tissue in comparison to MRI myocardial vitality findings. | time during hospitalization | Yes |
Secondary | feasibility and safety of echocardiography during catheter investigations | it will be analyzed if it is logistically possible to perform echo-test during the actual catheter investigations (feasibility) and if the patient will be exposed to any safety risk for logistic or sterility reasons. | time during hospitalization and 1 months afterwards | Yes |
Secondary | Determination of Strain-Parameter for identification of vital myocardial tissue | It will be determitated optimal Strain-Parameter(circumferential, systolic or diastolic)for identification of vital myocardial tissue | time during hospitalization | Yes |
