Case ReportsThe enigma of occult mitral regurgitation in a patient with cardiogenic shock.
In patients with mitral regurgitation (MR), there is a high pressure gradient between the left ventricle (LV) and left atrium that Doppler echocardiography can easily detect. We present a case where transthoracic echocardiography (TTE) failed to provide an accurate evaluation of a patient who presented in cardiogenic shock. A transesophageal echocardiogram diagnosed MR because of a flail leaflet caused by a ruptured papillary muscle in the setting of normal ventricular function.

Comparative StudyAssessment of left ventricular systolic and diastolic function by Doppler tissue imaging in patients with preinfarction angina.
The aim of this study was assessment of left ventricular (LV) systolic and diastolic function by pulsed wave Doppler tissue imaging (DTI) in patients with or without preinfarction angina in acute myocardial infarction. ⋯ LV diastolic function was better in patients with preinfarction angina than in patients without. This condition could not be detected by conventional mitral inflow Doppler velocities, but could be detected by DTI. This preliminary evidence shows that DTI is better than conventional mitral Doppler indices in the assessment of a favorable LV diastolic function in patients with preinfarction angina.
