Aortography and ventriculography are more specialized imaging techniques used in the cardiac catheterization laboratory for specific diagnoses and for specific indications. Ventriculography is an important diagnostic imaging modality to assess left ventricular function, regional wall motion abnormalities, severity of mitral regurgitation, certain congenital and shunt conditions such as ventricular septal defect.
During acute MI, ventriculography can be useful to determine an infarct zone or infarct artery. In some cases, ventriculography may make less common diagnoses such as ventricular aneurysms, Takotsubo cardiomyopathy, or ventricular diverticulae. Aortography is commonly used to make diagnoses in aortic valve disease as well as to define aortic pathology such as aneurysms. Occasionally, the location of venous bypass grafts are best determined by aortography. Proper technique and interpretation are always required.
