Öğe Cardiac hydatid cysts located in both the left ventricular apex and the intraventricular septum: Case report(Springer, 2000) Ulgen, MS; Alan, S; Karadede, A; Aydinalp, O; Toprak, NCardiac 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.Öğe Predischarge ST segment and T wave patterns in predicting left ventricular function and myocardial viability in Q wave anterior myocardial infarction patients(International Heart Journal Association, 2005) Karadede, A; Aydinalp, O; Sucu, MThe aim of this Study was to investigate the correlation between ECG changes prior to discharge and findings of early low dose dobutamine stress echocardiography (LDSE) performed in 6 +/- 2 days, in patients experiencing their first acute anterior MI. A total of 62 patients admitted with their first acute anterior MI were divided into three groups according, to the findings of electrocardiograms performed oil the 7-10th days: group A, isoelectric ST and negative or positive T wave; group B, ST elevation (>0.1 mV) and negative T wave; and group C, ST elevation and positive T wave. There were no significant differences between the groups with respect to thrombolytic therapy and reperfusion criteria. In addition, 90% of the patients in group A (20/22), 66% in group B (12/18 P < 0.05 versus group A), and only 54% in group C (12/22, P < 0.01 versus group A) responded to LDSE. The infarct zone wall motion score index (WMSI) measured by LDSE was significantly decreased in group A compared to basal values (from 2.71 +/- 0.65 to 2.07 +/- 0.71 P = 0.02), and it was significantly different compared to groups B and C. Moreover, the serum creatinine kinase level of the patients in group C was higher (P < 0.01 versus group A), whereas the ejection fraction was inferior (group A 48% group B 47%, and group C 41%, P = 0.04 versus group A). When the correlations between good left ventricular function and terminal QRS distortion, sum ST elevation, the number of leads with ST elevation, ST elevation shape oil admission, and ST and T alterations in ECG at discharge were investigated, all independent correlation was found between ST and T alteration in ECG and a WMSI value < 2 at rest or after LDSE (P 0.03, OR 3.08, 95%CI 1.05-8.98). At the infarct zone of patients with ST elevation and positive T waves, left ventricular function is worse and the viability is less. This simple classification may be useful in predicting left ventricular function at the time of discharge.Öğe The relationship between terminal QRS complex distortion and early low dose dobutamine stress echocardiography in acute anterior myocardial infarction(Japan Heart Journal, Second Dept Of Internal Med, 2004) Sucu, MM; Karadede, A; Aydinalp, O; Ozturk, O; Toprak, NAlthough the damage in myocardial infarction has been demonstrated to be related with the magnitude and number of ST elevation, its relation with terminal distortion of QRS is unclear. The relationship between terminal QRS distortion in ECGs on admission and the results of early low dose dobutainine stress echocardiography (LDSE) performed 6 +/- 2 days later was investigated. Patients admitted to our clinic within the first six hours of their chest pain and without a prior infarction diagnosis were divided into two groups based on the admission electrocardiogram as the absence (QRS-, n = 33) or presence (QRS+, n = 29) of distortion of the terminal portion of the QRS in greater than or equal to 2 leads (QRS+; J point at > 50% of the R wave amplitude in lateral leads or presence of ST elevation without S wave in leads V-1-V-3). There were no significant differences between the groups with respect to thrombolytic therapy or reperfusion criteria, During LDSE, the infarct zone wall motion score index (WMSI) in the QRS- group was significantly decreased relative to baseline (from 2.93 +/- 0.65 to 2.37 +/- 0.84, P = 0.02), and it was significantly different compared with WMSI in the QRS+ group (P = 0.005). Improvement of akinetic regions to hypokinetic regions in the infarct zone (IZ) was found to be 33:5% (44/131) in the QRS- group and 17.8% (27/ 151 P = 0.004) in the QRS+ group. Furthermore, 55.1% (10/29) of the patients in the QRS+ group and only 18.1% (6/33) of those in the QRS- group did not respond to LDSE (P > 0.05). In multiple logistic regression analysis, while. there was no relationship between good left ventricular functions (WMSI < 2) and terminal QRS distortion under basal conditions (P = 0.07), an independent relation was observed to exist between them after LDSE (P = 0.03, OR 4.48, 95% CI, 1.13-17.7). Moreover, plasma CK levels were higher in the QRS+ group (P = 0.03), whereas the ejection fraction was worse (P = 0.01). In both groups, there was no correlation between the Selvester score and left ventricle WMSI at baseline, but this correlation was significantly improved with LDSE (QRS-; r = 0.39 P 0.02 and QRS+; r = 0.44 P = 0.01). The viability in the IZ is relatively less in those patients with terminal QRS distortion observed in their ECG on admission. This simple classification would be useful in predicting left ventricular function at the time of discharge.Öğe The relationship of ST segment elevation shape with preserved myocardium and signal-averaged electrocardiography in acute anterior myocardial infarction(Springer-Verlag, 2002) Karadede, A; Aydinalp, O; Temamogullari, AV; Toprak, NAlthough 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 6h 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 pre-discharge 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 wits it higher viable myocardium, and lower LP(positivity) and in-hospital mortality in patients with concave ST elevation on admission.
