AIM: To find parameters from transthorathic echocardiography (TTE) including speckle-tracking (ST) analysis of the right ventricle (RV) to identify precapillary pulmonary hypertension (PH). METHODS: Forty-four patients with suspected PH undergoing right heart catheterization (RHC) were consecutively included (mean age 63.1 ± 14 years, 61% male gender). All patients underwent standardized TTE including ST analysis of the RV. Based on the subsequent TTE-derived measurements, the presence of PH was assessed: Left ventricular ejection fraction (LVEF) was calculated by Simpsons rule from 4Ch...

This report describes the case of a 19-year-old woman with a diagnosis of muscular ventricular septal defect. Bidirectional shunting was observed during a transthorathic echocardiography evaluation which also suggested normal pulmonary arterial pressure. Moreover, anomalous and hypertrophic right ventricular muscular bands were observed. After having ruled out other possibilities, the plausible explanation is one, which is not described in the literature. The findings may be explained as a sequestrated portion of the cavity of the right ventricle that remains isolated from the rest of the right ventricle (RV) by anomalous and hypertrophic right ventricular muscular bands, with communication only between the left ventricle and the sequestrated part of the RV...

We studied 19 patients with pericardial disease using two-dimensional and three-dimensional transthorathic echocardiography (2DTTE and 3DTTE, respectively) in order to determine whether 3DTTE provides incremental value on top of 2DTTE in the evaluation of these patients. With 3DTTE a more comprehensive assessment of pericardial effusion can be made and both the parietal and visceral layers of the pericardium can be visualized en face and examined for pathologies and fibrin deposits. In our series of patients, 3DTTE was superior to 2DTTE in uncovering mass lesions involving the pericardium such as tuberculous granulomas and metastatic disease...

We studied 31 patients with prosthetic valves (PVs) using two-dimensional and three-dimensional transthorathic echocardiography (2DTTE and 3DTTE, respectively) in order to determine whether 3DTTE provides an incremental value on top of 2DTTE in the evaluation of these patients. With 3DTTE both leaflets of the St. Jude mechanical PV can be visualized simultaneously, thereby increasing the diagnostic confidence in excluding valvular abnormalities and overcoming the well-known limitations of 2DTTE in the examination of PVs, which heavily relies on Doppler...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase

"primary prevention of cancer"
(heart or cardiac or cardio*) AND arrest -"American Heart Association"
