Current Hypertension Guidelines emphasize the importance of assessing the presence of preclinical organ damage. In fact, an extensive evaluation of organ damage may increase the number of patients classified at high CV risk and therefore strongly influence the clinical management of patients. Hypertensive heart disease remains to date the form of organ damage for which there is the greatest amount of evidence of a strong independent prognostic significance. In the presence of a chronic pressure overload, a parallel addition of sarcomers takes place with an increase in myocyte width, which in turn increases left ventricular wall thickness; myocyte hypertrophy is also associated with apoptosis, collagen deposition and ventricular fibrosis with an impairment of coronary hemodynamics as well, thus profoundly influencing functional properties of the left (and right) ventricle...

BACKGROUND: Non-invasive assessment of volume and function on the right ventricle (RV) for pulmonary hypertension (PH) is limited. METHODS AND RESULTS: Patients with PH (n=23) underwent 3-dimensional (D) echocardiography (3DECHO), with cardiac magnetic resonance imaging to confirm its precision, and right heart catheterization. On linear regression analysis the RV end-systolic volume index (ESVI) was positively correlated with pulmonary vascular resistance (PVR) and mean pulmonary arterial pressure (mPAP; R=0...

We present the case of a 57-year-old woman with severe aortic regurgitation and ventricular dysfunction (ejection fraction 34%) requiring surgical intervention. In pre-operative period, no left ventricular (LV) asynchrony was detected by QRS duration and current echocardiographic techniques, including tissue Doppler imaging. A new echocardiographic technology, the timing of regional volumetric changes by three-dimensional echocardiography (3DEcho), demonstrated an intraventricular mechanical asynchrony. Indeed, during surgery, epicardial leads were attached to the right atrium and the right ventricle as part of the standard management...

BACKGROUND: Quantitative three-dimensional echocardiography (3DEcho) of left ventricle (LV) is still limited because of the need for manually tracing endocardial borders: this can increase observer variability depending on the quality of fundamental (FUND) 2D images. We tested the combination of a simplified 3DEcho technique for LV reconstruction with automated endocardial border detection (Digital Echo Quantification, DEQ) and tissue harmonic imaging (THI) for enhancement of endocardium-cavity interface...

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"
