3D echocardiographic reference ranges for normal left ventricular volumes and strain: results from the EACVI NORRE study

2017

International audience; Aim: To obtain the normal ranges for 3D echocardiography (3DE) measurement of left ventricular (LV) volumes, function, and strain from a large group of healthy volunteers. Methods and results: A total of 440 (mean age: 45 ± 13 years) out of the 734 healthy subjects enrolled at 22 collaborating institutions of the Normal Reference Ranges for Echocardiography (NORRE) study had good-quality 3DE data sets that have been analysed with a vendor-independent software package allowing homogeneous measurements regardless of the echocardiographic machine used to acquire the data sets. Upper limits of LV end-diastolic and end-systolic volumes were larger in men (97 and 42 mL/m2)…

Morpho-volumetric assessment of the right ventricle: a comparison between three-dimensional echocardiography and cardiac magnetic resonance

2013

The morpho-volumetric assessment of the right ventricle (RV) is useful in the diagnosis and prognosis of many congenital and acquired cardiovascular diseases. The complexity of the right ventricular shape does not allow an adequate and satisfactory evaluation of the RV. Two-dimensional (2D) echocardiography is the most used tool for the assessment of RV function, as it is a noninvasive, reproducible and widespread technique, but the geometric assumptions required for measurement of RV volumes reduce its accuracy. At present, cardiac magnetic resonance is the gold standard for the evaluation of RV volumes because it does not need any assumption and is reproducible, though not always availabl…

Relocation of Papillary Muscles for Ischemic Mitral Valve Regurgitation

2014

Objective The assessment of the mitral valve apparatus (MVA) and its modifications during ischemic mitral regurgitation (IMR) is better performed by three-dimensional (3D) transesophageal echocardiography (TEE). The aim of our study was to carry out nonrestrictive mitral annuloplasty in addition to relocation of papillary muscles (PPMs) oriented by preoperative real-time 3D TEE through the mitral valve quantification dedicated software. Methods Since January 2008, a total of 70 patients with severe IMR were examined both before and after mitral valve repair. The mean (SD) coaptation depth and the mean (SD) tenting area were 1.4 (0.4) cm and 3.2 (0.5) cm2, respectively. Intraoperative 3D TEE…
