Abstract Cardiac hydatid cyst is rarely encountered and constitutes 0.5%–2% of all hydatid cases. Although left ventricular (LV) location for hydatid cysts has been frequently reported, the involvement of both the left ventricle and the interventricular septum (IVS) has not been previously reported in the literature. We present a case of cardiac hydatid cyst with fatal recurrent cerebral embolism and the unusual involvement of both LV and IVS demonstrated by transthoracic echocardiography.

Abstract Although a relation between magnitude of ST segment elevation and myocardial damage has been shown in the early period of acute myocardial infarction (AMI), such a relation between the shape of the ST segment elevation, myocardial damage, and the clinical course remains obscure. For this purpose 62 first anterior AMI patients admitted in the first 6 h were enrolled for the study. On the basis of precordial V3 derivation prior to thrombolytic therapy, the shape of the ST elevation was separated into three groups: concave (n = 26), straight (n = 24), or convex types (n = 12). The relation between the shape of the ST elevation recorded on admission, and the results of predischarge low-dose dobutamine stress echocardiography (LDE) performed (n = 53) and signal-averaged ECG values were investigated. The basal wall motion score index (WMSI) and response to LDE in the concave group were better in the infarct zone. Additionally, the average akinetic segment number in the infarct zone was higher, and improvement in these segments was less in the convex and straight groups (concave 3.78 ± 2 vs 2.17 ± 2.1, P < 0.01; straight 5.15 ± 2.7 vs 4.45 ± 2.8, not significant (NS); convex 5.4 ± 2.3 vs 4.8 ± 2.1, NS; basal vs LDE). While only 13% (3/23) of the patients did not respond to LDE (P < 0.05 vs group B and P < 0.01 vs group C), 35% (7/20) of group B and 60% (6/10) of group C patients did not respond to LDE. Although no relation was found between better left ventricular function (WMSI < 2) and shape of the ST elevation in basal evaluation by multiple logistic regression analysis (P = 0.06), an independent relation was found between them following LDE (P = 0.01, odds ratio (OR) 4.5, 95% Confidence Interval (CI) 1.3–14.7). The incidence of ventricular late potential (LP) positivity was 11% (3/26) in the concave group, 16% (4/24) in the straight group, and 58% (7/12) in the convex group (P < 0.001 vs concave and P < 0.05 vs straight groups). We found that shape of the ST elevation could significantly predict the presence of late potentials in multiple logistic regression analysis (P = 0.003, OR 10.7, 95% CI 2.2–51.7). There was no in-hospital death in the concave group, whereas five patients died in either the straight or the convex group. Furthermore, arrhythmia was lower in the concave group during this period (P < 0.05), and exercise capacity was lower. In conclusion, we determined that there was a higher viable myocardium, and lower LP(positivity) and in-hospital mortality in patients with concave ST elevation on admission.

Anomaly of the left anterior descending (LAD) coronary artery arising from the right sinus of valsalva is frequently seen with tetralogy of Fallot (TOF). The association of the LAD coronary artery with ventricular septal defect (VSD) is uncommon. We described an anomalous origin of the LAD coronary artery from the right sinus of valsalva with ventricular septal defect in a 38-year-old male patient suffering from atypical angina. The LAD coronary artery arose from the right sinus of valsalva, just next to the right coronary artery. There was a single opening in the membranous part of the interventricular septum. From this case, we suggest that angiography is useful for both documenting anomalies of the LAD coronary artery associated with VSD and for determining the safest surgical procedures.

The aim of this study is to investigate the value of hemodynamic changes induced by carotid sinus massage (CSM) on the diagnosis of coronary artery disease (CAD). A total 108 patients (mean age, 54 ±10 years, range 33-70) who had no significant stenosis in the carotid artery by duplex ultrasonography (USG) and no history of syncope were included in this study. Carotid sinus massage was performed before coronary angiography with monitoring of electrocardio graphy and blood pressure. The patients were divided into three groups according to response to CSM: group 1 patients had a decrease in blood pressure or < 10 beats/minute (bpm); group 2 patients had a decrease between 10 and 20 bpm; and group 3 patients had >20 mm Hg decrease in blood pressure or > 20 bpm. Coronary angiography was performed after CSM in all patients. There was single-vessel disease (VD) in 23 cases, two-VD in 24 cases, and three-VD in 35 cases. Coronary angiography results were normal in 26 cases. The changes in systolic and diastolic blood pressures and heart rate before and after CSM correlated with number of VD. These changes were highest in patients with three-VD, but lowest in patients with normal coronary angiography. The number of diseased vessels and total coronary artery score were lowest in group 1, but highest in group 3. The specificity and sensitivity of CSM-induced > 10 mm Hg in blood pressure (BP) or > 10 bpm changes in heart rate in the diagnosis of CAD were 85% and 71 %, respectively. The positive and negative predictive values were 93% and 49%, respectively in the diagnosis of CAD. At the end of this study, we concluded that CSM induced the fall in blood pressure and heart rate and was correlated with number of diseased vessels and the score of coronary artery disease. As dichotomized values, the decrease of > 10 mm Hg in blood pressure and/or >10 bpm has highest specificity, sensitivity, and positive predictive value in the diagnosis of CAD.
