Optimized Characterization of Takotsubo Syndrome by Obtaining Pressure Volume Loops

Patients with suspected Takotsubo syndrome (typical ballooning in left ventriculography without significant obstructive coronary artery disease that sufficiently explains the contraction abnormalities) will undergo continuous online measurements of left ventricular pressure and volume using conductance catheters. Cardiac magnetic resonance (CMR) imaging will be performed in patients without contraindications for optimized morphological characterization and exclusion of important differential diagnoses.
