Background/Objectives
Prevalence/incidence of sudden death due to cardiovascular disease in young competitive athletes has become an important part of the debate over the most effective and practical preparticipation screening strategies for this population. Since event reporting is not mandatory, identification of cases has been achieved largely through publicly available data and internet searches. The accuracy of this methodology has not been studied and deserves scrutiny.Methods
We assessed recognition of sudden cardiovascular deaths in college (NCAA) athletes with the U.S. National Registry of Sudden Death in Athletes that uses largely public domain sources, and also the NCAA Memorial Resolutions List.Results
For 2002–2011, 64 total sudden death cases were identified by both sources. The Registry identified 56 cases (88%), including 14 not found in the NCAA List. The NCAA List identified 50 cases (78%), including 8 unrecognized by the Registry (p = 0.16). Failure to initially recognize these 8 deaths using established Registry search mechanisms was due to the absence of key search terms in media reports. Cases not identified by the 2 methodologies did not differ significantly regarding demographics, cause of death, or sport.Conclusions
Internet-based, public domain methodology is useful and identified more cases of sudden cardiovascular death in college athletes than did the internal list provided by the NCAA. Nevertheless, these findings support the principle that multiple sources are additive and beneficial in identifying the maximum number of sudden death events. 相似文献903.

Background
The hydrodynamic cause of systolic anterior motion of the mitral valve (SAM) is unresolved.Objectives
This study hypothesized that echocardiographic vector flow mapping, a new echocardiographic technique, would provide insights into the cause of early SAM in obstructive hypertrophic cardiomyopathy (HCM).Methods
We analyzed the spatial relationship of left ventricular (LV) flow and the mitral valve leaflets (MVL) on 3-chamber vector flow mapping frames, and performed mitral valve measurements on 2-dimensional frames in patients with obstructive and nonobstructive HCM and in normal patients.Results
We compared 82 patients (22 obstructive HCM, 23 nonobstructive HCM, and 37 normal) by measuring 164 LV pre- and post-SAM velocity vector flow maps, 82 maximum isovolumic vortices, and 328 2-dimensional frames. We observed color flow and velocity vector flow posterior to the MVL impacting them in the early systolic frames of 95% of obstructive HCM, 22% of nonobstructive HCM, and 11% of normal patients (p < 0.001). In both pre- and post-SAM frames, we measured a high angle of attack >60° of local vector flow onto the posterior surface of the leaflets whether the flow was ejection (59%) or the early systolic isovolumic vortex (41%). Ricochet of vector flow, rebounding off the leaflet into the cul-de-sac, was noted in 82% of the obstructed HCM, 9% of nonobstructive HCM, and none (0%) of the control patients (p < 0.001). Flow velocities in the LV outflow tract on the pre-SAM frame 1 and 2 mm from the tip of the anterior leaflet were low: 39 and 43 cm/s, respectively.Conclusions
Early systolic flow impacts the posterior surfaces of protruding MVL initiating SAM in obstructive HCM. 相似文献907.

The presence of T-wave inversion (TWI) at 12-lead electrocardiogram (ECG) in competitive athletes is one of the major diagnostic challenges for sports physicians and consulting cardiologists. Indeed, while the presence of TWI may be associated with some benign conditions and it may be occasionally seen in healthy athletes presenting signs of cardiac remodeling, it may also represent an early sign of an underlying, concealed structural heart disease or life-threatening arrhythmogenic cardiomyopathies, which may be responsible for exercise-related sudden cardiac death (SCD). The interpretation of TWI in athletes is complex and the inherent implications for the clinical practice represent a conundrum for physicians. Accordingly, the detection of TWI should be viewed as a potential red flag on the ECG of young and apparently healthy athletes and warrants further investigations because it may represent the initial expression of cardiomyopathies that may not be evident until many years later and that may ultimately be associated with adverse outcomes. The aim of this review is, therefore, to report an update of the literature on TWI in athletes, with a specific focus on the interpretation and management. 相似文献

BackgroundLeft bundle branch block (LBBB) and left ventricular (LV) dyssynchrony likely contribute to progressive systolic dysfunction. The evaluation of newly recognized LBBB includes screening for structural heart abnormalities and coronary artery disease (CAD). In patients whose LV ejection fraction (EF) is preserved during initial testing, the incidence of subsequent cardiomyopathy is not firmly established.HypothesisThe risk of developing LV systolic dysfunction among LBBB patients with preserved LVEF is high enough to warrant serial imaging.MethodsWe screened records of 1000 consecutive patients with LBBB from our ECG database and identified subjects with an initially preserved LVEF (≥45%) without clinically relevant CAD or other cause for cardiomyopathy. Baseline imaging, clinical data, and follow‐up imaging were recorded to determine the risk of subsequent LV systolic dysfunction (LVEF ≤40%).Results(Data are mean + SD) 784 subjects were excluded, the majority for CAD or depressed LVEF upon initial imaging. Of the remaining 216, 37 (17%) developed a decline in LVEF(≤40%) over a mean follow‐up of 55 ± 31 months; 94% of these patients had a baseline LVEF≤60% and LV end systolic diameter (ESD) ≥ 2.9 cm indicating that these measures may be useful to define which patients warrant longitudinal follow‐up. The negative predictive value of a LVEF>60% and LVESD <2.9 cm was 98%.ConclusionsSeventeen percent of patients with LBBB and initial preserved LVEF develop dyssynchrony cardiomyopathy. We believe the risk of developing dyssynchrony cardiomyopathy is high enough to warrant serial assessment of LV systolic function in this high‐risk population. 相似文献
