Determinants of Secondary Pulmonary Hypertension in Patients with Takotsubo Cardiomyopathy.

Background: Although takotsubo cardiomyopathy (TTC) has been reported to have a favorable outcome, many complications may occur in the acute phase. Heart failure is the most common clinical complication in patients with TTC. We aimed to investigate determinants of secondary pulmonary hypertension (PH) in patients with TTC.

Comparison of real-time three-dimensional transesophageal echocardiography to two-dimensional transesophageal echocardiography for quantification of mitral valve prolapse in patients with severe mitral regurgitation.

Real-time 3-dimensional (3D) transesophageal echocardiography (TEE) provides more accurate geometric information on the mitral valve (MV) than 2-dimensional (2D) TEE. The aim of this study was to quantify MV prolapse using real-time 3D TEE in patients with severe mitral regurgitation. In 102 patients with severe mitral regurgitation due to MV prolapse and/or flail, 2D TEE quantified MV prolapse, including prolapse gap and width in the commissural view.
