Comparative value of transthoracic and transoesophageal echocardiography before balloon dilatation of the mitral valve
Why the study?
Does transoesophageal echocardiography improve the detection of left atrial thrombus compared to transthoracic echocardiography in patients with symptomatic dominant mitral stenosis before balloon dilatation?

Implication
Supports transoesophageal over transthoracic echocardiography for left atrial thrombus detection pre-mitral valvuloplasty; leaves open randomized outcome trials.
Structured PICO
Does transoesophageal echocardiography improve the detection of left atrial thrombus compared to transthoracic echocardiography in patients with symptomatic dominant mitral stenosis before balloon dilatation?
P
Population
35 consecutive patients with symptomatic dominant mitral stenosis being considered for balloon dilatation of the mitral valve.
I
Intervention
Transoesophageal echocardiography (TOE)
C
Comparator
Transthoracic echocardiography (TTE)
O
Outcome
Echocardiographic and surgical detection of left atrial thrombus and successful, uncomplicated balloon dilatation of the mitral valvesurrogate
Transoesophageal echocardiography is superior to transthoracic echocardiography for detecting left atrial thrombus before balloon dilatation of the mitral valve and is considered mandatory.
