Transoesophageal echocardiography in the assessment of percutaneous mitral commissurotomy
Why the study?
Does transoesophageal echocardiography improve the detection of left atrial thrombi and mitral regurgitation compared to transthoracic echocardiography in patients undergoing percutaneous mitral commissurotomy?
Population
110 patients evaluated for percutaneous mitral commissurotomy
Comparison
Transoesophageal echocardiography (TEE) vs Transthoracic echocardiography (TTE)

Implication
Supports TEE for pre-procedural LA thrombus screening in mitral commissurotomy; extends observational comparisons but leaves open outcome impact.
Structured PICO

P
Population

I
Intervention
Transoesophageal echocardiography (TEE)
C
Comparator
Transthoracic echocardiography (TTE)
O
Outcome
Detection of left atrial thrombus, mitral regurgitation, spontaneous contrast, and post-PMC atrial septal defectsurrogate
TEE is superior to TTE for detecting left atrial thrombi, mitral regurgitation, and post-procedural atrial shunts in patients undergoing percutaneous mitral commissurotomy, though TTE remains necessary for calculating valve area.
