Table 2 Advantages and disadvantages of three methods of estimation of left-sided valve's regurgitation.

From: Methods of estimation of mitral valve regurgitation for the cardiac surgeon

Mode of evaluation Advantages Disadvantages
Angiography -simultaneous calculation of SVR, PVR, LVEDP, PCWP, EF, etc (1,6)
-easy interpretation by cardiologists and cardiac surgeons (6)
-invasive method, risk of complications(5)
-misinterpretation in double valve disease (1,6)
-higher cost (5,6)
-temporarily affects hemodynamic of patient (SVR, PVR) and obscure the results (5)
Doppler - non-invasive method
- no risks
- low-cost
- time-consuming
- does not affect hemodynamically the patient
- semi-quantitative
- overlapping structures
- "bad" window
- operator depending
discomfort+hemodynamic interaction of TEE – limitations (see text)
- influence of site of Jet
MRI - measurement of LVEDV, LVESV, LV mass
- no risk
- non invasive tool
- precise and valid estimation (23,24)
- does not need suppression or anaesthesia (such as TEE)
- estimation of myocardial function and viability (9,29)
- respiratory interference
-not-hemodynamic measurement
- not-anatomic information
- discomfort for the patient
- artefacts in the case of metallic materials (40,41)
  1. (SVR: systemic venous resistance, PVR: pulmonary venous resistance, PCWP: pulmonary capillary wedge pressure, EF: enjection fraction, LVEDV: left ventricle end diastolic volume), LVESV: left ventricle end systolic volume, LV mass: left ventricle mass, TEE: Transesophageal echocardiography).
