Table 2. Advantages and Disadvantages of MV Imaging between Echocardiography and Cardiac CT.

	Echocardiography	Cardiac CT
Advantages	Fundamental information: valve disease including flow measurements Readily available, cost-effective and safe	High spatial resolution Detailed depiction of MV anatomy Simultaneous evaluation of adjacent anatomic structures Rapid acquisition Collection of three-dimensional dataset Wide availability during off-hours
Disadvantages	Operator-dependence High interobserver variability Poor acoustic windows	Radiation exposure Need for iodinated contrast material Inferior temporal resolution No hemodynamic information

MV = mitral valve
