BACKGROUND: Hypertrophic cardiomyopathy (HCM) represents a generalized myopathic process affecting both ventricular and atrial myocardium. We aimed to assess left atrial (LA) function by two-dimensional speckle tracking echocardiography and its relation with left ventricular (LV) function and clinical status in patients with HCM. METHODS: We prospectively enrolled 37 consecutive patients with HCM and 37 normal subjects with similar age and gender distribution. Longitudinal LV strain (epsilon) and LA epsilon and strain rate (Sr) parameters (systolic, early diastolic, and late diastolic during atrial contraction) were assessed. RESULTS: Peak LAepsilon and LA Sr parameters were significantly lower in patients compared with controls (P </= .001 for all). In patients, all LA function parameters correlated with LVepsilon (P < .003 for all). Indexed LA volume, LA function parameters, and mitral regurgitation degree were the main correlates of New York Heart Association class; late diastolic strain rate during atrial contraction was the only independent predictor of symptomatic status. CONCLUSION: In patients with HCM, LA function is significantly reduced and related to LV dysfunction. Moreover, LA booster pump function emerged as an independent correlate of heart failure symptoms in this setting. [less ▲]

AIMS: The present study sought to determine the relationship between left atrial (LA) volume (structural changes) and LA function as assessed by strain rate imaging in patients with aortic stenosis (AS). <br />METHODS AND RESULTS: The study consisted of a total of 64 consecutive patients with severe AS (<1 cm²) and 20 healthy control subjects. The phasic LA volumes and function (tissue Doppler-derived strain) were assessed in all patients. As compared with healthy controls, all strain-derived parameters of LA function were reduced in patients with AS. Conversely, only indexed LA passive volume (increased) (7.6 ± 3.8 vs. 10.5 ± 5.1 ml/m², P= 0.02) and LA active fraction (decreased) (43 ± 6.7 vs. 31 ± 13.3%, P< 0.001) (volume-based parameters) were significantly different between AS and controls. In AS, LA volume-derived function parameters were poorly correlated with LA strain parameters. In fact, by multivariable analysis, no LA phasic strain parameters emerged as independently associated with LA phasic volume parameters. <br />CONCLUSIONS: In AS, changes in LA function did not parallel changes in LA size. Furthermore, the increase in LA volume does not necessarily reflect the presence of intrinsic LA dysfunction [less ▲]

Cerebral blood flow was estimated using positron emission tomography and H2O15 infusions in 12 volunteers while they were trained on the probabilistic serial reaction time task developed by Jimenez, Mender, and Cleeremans (1996). Participants' reaction rimes to predictable and nonpredictable stimuli showed increasing sensitivity to the: probabilistic constraints set by previous elements of the sequence. Analysis by statistical parametric mapping showed a significant interaction between participants' performance and time effect in the left inferior frontal cortex. Our results provide the first evidence of this cerebral area being involved in the processing of contextual information in a probabilistic sequence learning task. [less ▲]

One of the most consistently activated regions during verbal short-term memory (STM) tasks is the left intraparietal sulcus (IPS). However, its precise role remains a matter of debate. While some authors consider the IPS to be a specific store for serial order information, other data suggest that it serves a more general function of attentional focalization. In the current fMRI experiment, we investigated these two hypotheses by presenting different verbal STM conditions that probed recognition for word identity or word order and by assessing functional connectivity of the left IPS with distant brain areas. If the IPS has a role of attentional focalization, then it should be involved in both order and item conditions, but it should be connected to different brain regions, depending on the neural substrates involved in processing the different types of information (order versus phonological/orthographic) to be remembered in the item and order STM conditions. We observed that the left IPS was activated in both order and item STM conditions but for different reasons: during order STM, the left IPS was functionally connected to serial/temporal order processing areas in the right IPS, premotor and cerebellar cortices, while during item STM, the left IPS was connected to phonological and orthographic processing areas in the superior temporal and fusiform gyri. Our data support a position considering that the left IPS acts as an attentional modulator of distant neural networks which themselves are specialized in processing order or language representations. More generally, they strengthen attention-based accounts of verbal STM. [less ▲]

A 32-year-old woman had acute anterior myocardial infarction after a mild chest trauma (automobile accident). Unstable angina recurred shortly after admission, and extensive dissection of the left coronary artery was demonstrated. Medical therapy including systemic fibrinolysis was started but clinical stabilization and good long-term result was achieved only by aortocoronary bypass grafting. [less ▲]

Left ventricular dyssynchrony (LVD) is common in heart failure patients with LV systolic dysfunction. Contrary to what it could be expected, LVD is not a stable phenomenon. Various conditions (inducible ischemia, exercise, drug administration) may significantly alter the presence and the magnitude of LVD, which could per se modulate response to treatment for heart failure. LVD can be evaluated using validated Doppler-echocardiographic techniques as tissue Doppler imaging. Exercise and dobutamine stress echocardiography can be used tests to unmask LVD. Changes in LV synchronicity during stress test occur independently of inducible ischemia and irrespective of QRS width. The degree of LVD varies substantially from patient to patient. The dynamic increase in LVD represents a strong contributor: (1) to exercise-induced changes in mitral regurgitation, (2) to limitation of stroke volume adaptation during exercise, and (3) to exertional dyspnea. Whether dynamic LVD might independently affect the outcome has not yet been demonstrated. In the setting of CRT, the assessment of dynamic LVD might help patient selection, predict the magnitude of response, and optimize pacing delivery during exercise. Further longitudinal studies are required to confirm the value of assessing dynamic LVD. [less ▲]
