Contrast echocardiography during cardiac catheterization in patients with congenital heart diseases.
Contrast echocardiography performed during cardiac catheterization has mostly been limited to a few published case reports. We studied 37 patients with congenital heart disease to assess the capability of the method to diagnose cardiac shunts and valve regurgitation. Injections of 5% dextrose in water through an angiographic catheter were made to evaluate septal integrity and valve competence compared with conventional contrast angiography. An overall sensitivity of 93% and specificity of 78% were found. In four cases of atrial septal defect and seven of mitral regurgitation, the sensitivity was 100%. It was slightly lower for eleven cases of ventricular septal defect (91%) and four of patent ductus arteriosus (75%). When assessing aortic, tricuspid and pulmonary valve competence, the method proved to be more sensitive than conventional angiography to detect mild regurgitation. Contrast echocardiography is a sensitive and safe technique that may be used in association with conventional angiography reducing the need for radiographic contrast and ionizing radiation time.
