Concepts for interventional MRI and computer assisted surgery in congenital heart diseases

Abstract : An integrated approach to assess ventricular pump function, diastolic compliance, myocontractility and vascular function would be of high clinical value. To date, MRI is considered the gold standard for quantifying ventricular volumes and blood flow and recent advances in fast imaging techniques made MRI catheterization a reality. The combination of invasive pressures with MRI derived volumes was demonstrated to provide accurate estimates of the endsystolic pressure-volume relationship, which is considered the optimal quantification of systolic ventricular function. In addition, MRI catheterization was shown to provide accurate vascular resistance measurements. We recently extended and validated this method for additional acquisition of diastolic compliance and demonstrate the clinical utility of MRI catheterization in the assessment in patients with complex hemodynamique conditions.
