Overall, conventional echocardiography can detect some differences between young athletes with eccentric and concentric type of athlete's heart but it is incapable of revealing differences in intrinsic myocardial functions. However, analysis using STE demonstrated increased systolic functions in athletes commensurate with increased load, with unaltered diastolic functions.

Carbon monoxide (CO) poisoning is the leading cause of death from intoxication. In CO poisoning, it is important to know if there are any symptoms regarding myocardial damage, which are usually unobserved as a result of hypoxia. This study was planned to assess myocardial damage in young healthy patients with CO poisoning. Eighty-three young healthy cases who had been exposed to CO were included in this study. The demographic and clinical characteristics, the origin of CO gas and smoking habits of the patients were recorded. The evaluation of ECG, peripheral ABG, complete blood count and serial cardiac biomarkers (creatine kinase, creatine kinasemyocardial band and troponin I) measurements were performed in all cases. Additionally, echocardiogram (ECHO) and myocardial perfusion single-photon emission computed tomography (SPECT) were performed at the appropriate times in all cases. The mean age of the patients was 27.39 /10.9 years. The main complaint of the patients was loss of consciousness with a 62.7% rate. The average carboxyhaemoglobin level of the patients was 34.49 /15.9%. Sinus tachycardia was present in 26.5% of patients. Diagnostic ischaemic ECG changes were present in 14.4% of patients. In myocardial SPECT, myocardial ischaemic damage was observed in 9 cases, in 6 of whom ECHO findings were also confirmed. Myocar-dial damage due to CO poisoning should not be ignored. If patients are at risk in terms of myocardial damage, further studies, such as ECHO and scintigraphy are needed to determine myocardial damage resulting from CO poisoning. However, in the young adults of the risk group, if the baseline ECG and serial cardiac biomarkers are normal, further studies such as ECHO and scintigraphy, considering the length of exposure and the severity of poisoning, may not be necessary for the evaluation of myocardial damage due to CO poisoning.

Atrial appendage aneurysms are extremely rare entities in cardiology practice. There are reports of solitary left and right atrial appendage aneurysms in the literature. A case of biatrial appendages aneurysms is reported here. This is the first report of such an anomaly.

This study demonstrates that right ventricular strain and strain rate were lower in patients with left ventricular inferior wall myocardial infarction with, compared to without, right ventricular infarction.

After regular and prolonged training, some physical and structural changes occur in the heart. Strain (S) imaging and Strain Rate (SR) imaging are new and effective techniques derived from tissue Doppler imaging (TDI) which examine systolic and diastolic functions. The aim of the present study was to evaluate left ventricular TDI and S/SR imaging properties in athletes and sedentary controls. The study population consisted of 26 highly trained athletes (group I) and age, sex and body mass index (BMI) adjusted 23 control subjects (group II) who had no pathological conditions. Using standard transthoracic and Doppler echocardiographical measurements and reconstructed spectral pulsed wave tissue Doppler velocities, the S/SR imaging of six different myocardial regions were evaluated. There was a significant increase in left ventricular systolic (LVSD) and diastolic (LVDD) diameter, inter-ventricular septum (IVS), left ventricular mass (LVm), left atrial diameter (LA), and transmitral Doppler peak E velocity (flow velocity in early diastole) between group I and group II in the case of echocardiographic findings. In athletes, TDI analysis showed a significantly increased mitral annulus lateral TDI peak early diastolic (E) velocity (18.8 ± 4.1 cm/s vs. 15 ± 3.5 cm/s, P < 0.01), septal TDI peak E velocity (15.8 ± 2.8 cm/s vs. 12.8 ± 2.4 P < 0.001). There were no significant differences in myocardial velocity imaging parameters between group I and group II. Peak systolic strain/strain rates of septal and lateral walls in group I were significantly higher than group II. This study demonstrates that left ventricular S/SR imaging was higher in athletes than in healthy subjects. In addition to traditional echocardiographic parameters, SI/SRI could be utilised as a useful echocardiographic method for cardiac functions of athletes.
