SUMMARYThe incidence and nature of cardiac involvement in Behçet's disease are not yet clearly documented. We first used transesophageal echocardiography in combination with resting and signal averaged electrocardiography to define cardiac involvement in Behçet's patients. Transthoracic and multiplane transesophageal echocardiography, and resting and signal averaged electrocardiography were performed in 35 Behçet's disease patients (9 women and 26 men, mean age: 38±12 years) and 30 normal subjects. Higher incidences of interatrial septum aneurysm (31% to 6%), mitral valve prolapse (25% to 3%), mitral regurgitation (40% to 6%) and aneurysmal dilatations of sinus valsalva and ascendan aorta were observed in the Behçet's disease patients than in the normal subjects. Mean QT dispersion and mean corrected QT dispersion values were significantly greater in the patients with Behçet's disease. Patients with interatrial septum aneurysm (and/or PFO), valvular dysfunction or proximal aorta dilatation had greater QT dispersion values than thase without these pathologies in the Behçet's group (63±11 vs 44±19 ms, 58±23 vs 41±24 and 60±27 vs 42±23 ms respectively, P<0.05). Positive signal averaged electrocardiography parameters were detected in 18 (51%) Behçet's disease patients compared with one (3%) in controls (P<0.001). Dilatation of the proximal aorta, interatrial septal aneurysm, mitral valve prolapse, and mitral regurgitation are the common findings of cardiac involvement in Behçet's disease. Increased dispersion of ventricular repolarisation and positive late potentials are also detected. QT dispersion is significantly higher in patients with these cardiac abnormalities. These findings suggest that cardiac involvement in this disorder is a diffuse process which involves both cardiac structure and vascular elements.

Background and Aim: Stable angina pectoris is a common disease that may cause disability. Some noninvasive new methods can be useful for the detection of earlystage coronary artery disease. The relationship between coronary artery disease (CAD) severity and resting 3-dimensional-speckle tracking echocardiography (3D-STE) in stable angina pectoris patients was evaluated in this study. Methods:One hundred and twenty consecutive patients between 18-80 years of age and without a history of CAD to whom elective coronary angiography was planned after positive stress test or myocardial perfusion scintigraphy were enrolled in the study. 3D-STE was performed and global longitudinal strain (GLS), global circumferential strain (GCS), global radial strain (GRS), and global area strain (GAS) were measured before coronary angiography. A Gensini score of ≥20 was accepted as critical CAD. Correlation between Gensini scores and 3D-STE results were evaluated.Results: Mean age was 60.7 ± 10.01 years, and 55% of the patient population were male. There were not any significant differences between critical CAD and noncritical CAD groups for age, gender, history of hypertension, diabetes mellitus, hyperlipidemia, and Left Ventricular Ejection Fraction. Mean GLS was −12, GCS was −18.8, GRS was 33.4, GAS was −28.9, and mean Gensini score was 18.8. GLS and all other strain parameters were significantly worse in patients with critical CAD group compared with noncritical CAD group and also positive linear correlation was observed between Gensini score and all measured strain parameters (r = 0.568, P < 0.001 for Gensini score and GLS; r = 0.617, P < 0.001 for Gensini score and GAS). A GLS value of >−10 has 88.9% sensitivity and 92.9% specificity; A GAS value of >−21 has 97.2% sensitivity and 88.1% specificity to detect critical CAD.Conclusions: 3D-STE is a noninvasive and handy parameter to detect subclinical left ventricular dysfunction and global strain values were significantly correlated with CAD severity. GAS has the sensitivity of 97.2% and specificity of 88.1% to detect critical CAD. Adding 3D strain echocardiography to exercise test or myocardial perfusion scintigraphy might increase sensitivity to detect critical CAD in clinical practice.

Professional football playing is associated with morphologic alteration in left ventricle and left atrium and improvement in left ventricle diastolic function that can be detected by TDI and Vp. These techniques may be new tools to define and quantitate the degree of LV diastolic adaptations to endurance exercise.
