The current echocardiographic diagnostic criteria for noncompaction cardiomyopathy (NCC) have variable sensitivity and low specificity. Moreover, there are limited data on the use of myocardial deformation imaging for early detection of myocardial dysfunction in children with NCC. We describe left ventricular (LV) deformation patterns in children with NCC, with the goal of identifying a potential diagnostic pattern. We prospectively enrolled 30 children with NCC (47% male; mean age 7.2 years) and 30 age- and gender-matched controls...

OBJECTIVES: This study determined the relationship between the timing of left ventricular (LV) electrical activation and peak contraction at potential LV pacing locations in candidates for cardiac resynchronization therapy (CRT). BACKGROUND: Targeting the LV lead to the region of latest electrical activation or the segment of latest peak contraction has both been shown to improve CRT response. Whether these regions correspond within CRT patients is uncertain. METHODS: Twenty-eight consecutive CRT candidates underwent intraprocedural coronary venous electroanatomic mapping using EnSite NavX...

BACKGROUND: Echocardiographic assessment of systolic and diastolic function during atrial fibrillation (AF) is challenging. This study evaluates the prognostic value of strain in patients with AF and suggests a novel approach on how to take into account the varying heart cycle lengths in AF. METHODS: Echocardiograms from 204 patients with AF during examination were analyzed offline. Patients with known heart failure (HF) were excluded. Peak global longitudinal strain (GLS) was averaged from 18 myocardial segments...

Despite its proven superiority over two-dimensional transthoracic echocardiography (2DTTE) for left ventricular (LV) volumes and ejection fraction, clinical use of 3DTTE remains very limited in the acute setting. 3DTTE may have significant clinical advantages in the assessment of acute heart failure. Further exploration of 3DTTE utilization may help in more precise assessment of the regional wall-motion abnormalities, early identification of acute ischemic from nonischemic LV dysfunction with a more precise approach to the AHF management...

In hypoplastic left heart syndrome (HLHS), long-term outcome is closely related to right ventricular function. Echocardiography and magnetic resonance imaging (MRI) are routinely used for functional assessment. MRI 2D-tissue feature tracking (2D-FT) allows quantification of myocardial deformation but has not yet been applied to HLHS patients. We sought to investigate the feasibility of this technique and to compare the results to 2D-speckle tracking echocardiography (2D-STE). In routine MRI 2D anatomical four chamber view, cine images were recorded in 55 HLHS patients (median age 4...

REVIEW
Mark K Friedberg
The impact of one ventricle on the adjacent ventricle plays a key role in cardiac function. Ventricular-ventricular interactions are based on the arrangement in-series of the circulation and common pericardium, interventricular septum, and myocardial tracts. Imaging, in particular echocardiography, plays a central role in characterizing these interactions through geometric indices, septal configuration and motion, Doppler flow, timing of events in the ventricles and alterations in strain, remodeling, and diastolic filling with altered loading of the contralateral ventricle...

To achieve further risk stratification in hypertrophic cardiomyopathy (HCM) patients, we localized and quantified layer-specific LVM fibrosis on MRI in HCM patients using regional layer-specific peak longitudinal strain (PLS) and peak circumferential strain (PCS) in LV myocardium (LVM) on speckle tracking transthoracic echocardiography (TTE). A total of 18 HCM patients (14 males; 58 ± 17 years) underwent 1.5T-MRI and TTE. PLS and PCS in each layer of the LVM (endocardium, epicardium, and whole-layer myocardium) were calculated for 17 AHA-defined lesions...

We sought to assess the inheritance of left ventricular (LV) function using speckle-tracking echocardiography and the impact of hypertension on modifying the genetically determined pattern of contraction in a population of twins. We recruited 92 Caucasian twin pairs, including 74 hypertensive (HTN) siblings. Beyond standard echocardiographic protocol, a speckle-tracking analysis was performed, including global longitudinal strain (GLS). Systolic function, as assessed by ejection fraction, showed moderate heritability (61%); however, GLS showed higher and dominant heritability (75%)...
