Secondary mitral regurgitation (MR) assessment is complicated by left ventricular (LV) changes. Cardiac MRI is optimal for quantifying LV volume data, crucial for managing secondary MR.
Area of Science:
- Cardiology
- Medical Imaging
Background:
- Secondary mitral regurgitation (MR) arises from left ventricular (LV) dilation and dysfunction.
- This complicates the evaluation and management of secondary MR.
Purpose of the Study:
- To review the assessment of secondary MR.
- Emphasis on quantification and analysis of LV volume data.
Main Methods:
- Cardiac MRI is identified as the optimal method for LV volume measurements.
- Analysis of regurgitant fraction (RF), LV end-diastolic volume (EDV), and regurgitant volume (RegV).
Main Results:
- Severe MR (primary and secondary) shows RF >50% and increased LV EDV.
- Secondary MR often has depressed ejection fraction (<40%) and RegV below severe criteria (>60 mL).
- The low RegV to EDV ratio in secondary MR may predict LV size changes post-MR correction.
Conclusions:
- Accurate measurement of LV volumetric parameters is essential for effective management of secondary MR patients.
- Cardiac MRI provides optimal quantification for this purpose.
