Should we use echocardiography to screen young athletes?
September 02, 2008Sudden and unexpected deaths in young competitive athletes are uncommon but highly visible events, which raise concern and ethical issues in both the lay public and medical community. Which is the best strategy to timely identify individuals with cardiac disease responsible for sudden death (primarily, HCM) is largely debated. Namely, the extent to which sophisticated testing, such as echocardiography, is needed is still undefined.
To address this question, we carried out an echocardiographic assessment of the structural cardiac diseases in a population of 4,450 athletes, initially judged free of cardiac disease and eligible for competition on the basis of pre participation screening with 12-lead ECG.
None of the 4,450 athletes showed evidence of HCM. Other cardiac abnormalities were detected in only 12 athletes, including myocarditis (n=4), mitral valve prolapse (n=3), Marfan's syndrome (n=2), aortic regurgitation with bicuspid valve (n=2), and arrhythmogenic right ventricular cardiomyopathy (n=1). In addition, 4 athletes were identified with borderline LV wall thickness (i.e., 13 mm) in the "gray-zone" between HCM and athlete's heart. In 2 of these athletes, subsequent genetic analysis or clinical changes over an average 8-year follow-up resulted, respectively, in a diagnosis of HCM.
In conclusion, the pre participation screening program including 12-lead ECG appears to be efficient in identifying young athletes with HCM, leading to their timely disqualification from competitive sports. These data also suggest that routine echocardiography is not an obligatory component of large population screening programs designed to identify young athletes with HCM.

Echocardiography Current Events and Echocardiography News RSSArtificial intelligence helps diagnose cardiac infections
Mayo Clinic researchers say that "teachable software" designed to mimic the human brain may help them diagnose cardiac infections without an invasive exam.
Half of eligible patients not getting mitral valve surgery, U-M study shows
Overblown fears about surgical risk and lack of awareness about the risk of not operating are among the reasons only half of eligible patients were referred for mitral valve repair, according to a study by doctors at the University of Michigan Cardiovascular Center.
Infective endocarditis: An old but changing disease
Infective endocarditis (IE) is a severe form of valve disease characterized by infection located in the valves of the heart.
Screening for left ventricular dysfunction may have less value than thought
The value and cost-effectiveness of screening for left ventricular (LV) dysfunction remains unclear, particularly since specific, evidence-based treatments are not available for the majority of patients with preserved systolic dysfunction.
Expert consensus on catheter ablation of ventricular arrhythmias
A call to action for more research to be undertaken into catheter ablation in the field of ventricular arrhythmia (VA) has been issued in a joint consensus document from the European Heart Rhythm Association (EHRA) a registered branch of the European Society of Cardiology (ESC) and the US Heart Rhythm Society (HRS).
More patients needed in clinical trials to find treatment for heart condition linked to certain strokes
The American Heart Association and the American College of Cardiology are calling on doctors to enroll more patients in clinical trials for catheter-based closure of patent foramen ovale (PFO), a condition caused when an opening between the two chambers of the heart fails to close at birth.
Linked angina relates with gastroesophageal reflux diseases?
It is well known that non-cardiac chest pain is closely related to gastroesophageal reflux diseases (GERD). Chest pain of esophageal origin can be difficult to distinguish from that caused by cardiac ischemia because the distal esophagus and the heart share a common afferent vagal supply, and GERD can cause episodes of non-cardiac chest pain that resemble ischemic cardiac pain.
Accurate Assessment of Heart Disease Leads to Earlier, More Aggressive Therapy
In a study comparing the ability of various medical techniques to accurately determine the extent of heart disease and stratify patients according to disease severity, researchers found that myocardial perfusion testing with gated single photon emission computed tomography (gated SPECT) was a more accurate predictor of prognosis in chronic ischemic heart disease (IHD)-a painful condition caused by a temporary reduction of oxygen-rich blood to the heart.
Improved predictive value of biomarkers in HF makes earlier diagnosis and better management possible
With an ever ageing population and more people surviving a heart attack, heart failure is now the world's most prevalent chronic cardiovascular disease. Yet despite improvements in its diagnosis and management, heart failure remains a stubbornly incurable condition with a poor prognosis, largely amenable to little more than palliative therapy.
Abnormal heart function associated with reduced capacity for exercise
Patients with abnormal diastolic function (when the heart is relaxed and expanded) in the left ventricle of the heart have a substantially lower maximum capacity for exercise, according to a study in the January 21 issue of JAMA.
