Objectives: The aim of this study was to detect undiagnosed ischemic heart disease (IHD) using dipyridamole myocardial perfusion imaging (MPI) in HD patients. Patients and Methods: In this cross-sectional descriptive study, HD patients who met the inclusion criteria were selected. Demographic, clinical, and paraclinical data were obtained via interviews and medical records. Bedside electrocardiography, resting echocardiography, and nuclear MPI with dipyridamole were done. The data were analyzed using descriptive statistical methods for detecting the prevalence of undiagnosed IHD in the HD patients. The chi-square test and the independent t-test were used to identify the high-risk HD patients. Results: Sixty-nine HD patients were studied using dipyridamole MPI with Tc 99 m sestamibi. The mean age, body mass index, and mean duration of HD were 52.1 ± 13.8 years, 21.23 ± 4.79 kg/m2, and 48.2 ± 34.9 months, respectively. The patients were divided into two groups based on MPI: IHD-positive group (21.7%) and IHD-negative group (78.3%). IHD was more prevalent in the patients with diabetes mellitus, hypertension, positive family history of CAD, low HD adequacy index (Kt/V < 1.2), left ventricular hypertrophy, high intact parathyroid hormone levels, electrocardiographic abnormalities, and low ferritin levels. A statistically significant correlation was also detected between IHD and aging (P < 0.05). Conclusions: The prevalence of undiagnosed IHD in the HD patients was considerable. We, therefore, suggest that IHD be assessed in HD patients, especially those at high risk due to positive family history of CAD, hypertension, left ventricular hypertrophy, diabetes mellitus, Kt/V < 1.2, low ferritin levels, and high levels of intact parathyroid hormone.","PeriodicalId":429543,"journal":{"name":"Archives of Cardiovascular Imaging","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132244348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dysfunction in hemoglobin chain production, ineffective erythropoiesis, and hemolysis occur in β-thalassemia. Pulmonary arterial hypertension (PAH) is increasingly detected in patients with β-thalassemia, and splenectomy which decreases the need for blood transfusion increases the pulmonary artery pressure (PAP). Objectives: This study aimed to assess the PAP in patients with β-thalassemia (male or female and major or intermedia) who had undergone splenectomy. Methods: A total of 137 patients suffering from β-thalassemia were evaluated during the study. All subjects were referred for cardiac evaluation. Clinical history, presence of cardiac symptoms, and previous splenectomy were noted. Standard M-mode, 2D, and Doppler echocardiographic examinations were performed for all subjects. Patients with a tricuspid regurgitant jet velocity (TRV) ≥2.5 m/s were considered at risk for PAH. Results: Average age of the patients was 21.15±6.68 years. No significant difference was observed in the PAP between the 2 groups of thalassemia major and intermedia and also the 2 sex groups. Indeed, 6.6% of the patients had an increased PAP. The significant finding of the study was that the patients who had had splenectomy were significantly at an increased risk of PAH (P = 0.046). Conclusions: The etiology of PAH in thalassemia is multifactorial such as inflammatory mediators. Also, the absence of the spleen plays an important role in developing a high TRV and PAH.","PeriodicalId":429543,"journal":{"name":"Archives of Cardiovascular Imaging","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116166494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mechanism of vibratory innocent murmur is still unclear. Objectives: The aim of this study is to learn the mechanism of the vibratory innocent murmur. Patients and Methods: The prospective cross-sectional study was conducted using 32 children who had the vibratory innocent murmur (cases) in Chiang Mai University Hospital and 27 normal healthy children (controls). Two-dimension, Doppler, and tissue Doppler echocardiography were performed on each subject to examine the difference between cases and controls. Results: The left ventricular false tendon was present in 84% of cases and 22% of controls (P < 0.001). Left ventricular outflow tract velocity was significantly higher in cases than in controls (P < 0.001). Early diastolic myocardial velocity at the base of the interventricular septum was lower in cases with false tendon than those without false tendon (P = 0.048). No significant difference was found regarding ascending aorta diameter, cardiac output and ejection fraction between the two groups. Left ventricular diastolic function was normal in all cases and controls. Conclusions: The vibratory innocent murmur is associated with the presence of left ventricular false tendon and higher left ventricular outflow tract velocity. The presence of the left ventricular false tendon was somewhat associated with decreased early diastolic myocardial velocity. Normal left ventricular systolic and diastolic function can be used as a reassurance in cases with the vibratory innocent murmur.","PeriodicalId":429543,"journal":{"name":"Archives of Cardiovascular Imaging","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130855966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ventricular dyssynchrony was assessed in patients with heart failure. In sub-Saharan Africa, very few studies have focused on ventricular dyssynchrony in healthy subjects. Objectives: The purpose of this study was to measure time-to-peak of systolic and diastolic velocities of different segments of left ventricle and apply ventricular dyssynchrony markers to healthy black African subjects. Patients and Methods: Fifty healthy black African were enrolled consecutively over a period of 3 months. Time-to-peak systolic velocities (TS) and Time-to-peak early diastolic velocities (TE) were measured at the four basal segments of left ventricle. Five dyssynchrony markers were assessed: difference between maximal time-to-peak systolic velocity and minimal time-to-peak systolic velocity, time between septal time-to-peak systolic velocity and lateral time-to peak systolic velocity, standard deviation of time-to-peak systolic velocity of the four basal segments, difference between maximal time-to-peak early diastolic velocity and minimal time-to-peak early diastolic velocity, and standard deviation of time-to-peak early diastolic velocity of the four basal segments. Results: The frequency of some dyssynchrony markers was similar to that of other studies. The difference between maximal time-to-peak systolic velocity and minimal time-to-peak systolic velocity was correlated with age and was higher among women. The prevalence of diastolic dyssynchrony was higher in black African subjects. Conclusions: Large-scale studies on the healthy black African population could assess the relationship between diastolic dyssynchrony and changes in myocardial performance related to racial differences.","PeriodicalId":429543,"journal":{"name":"Archives of Cardiovascular Imaging","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124142416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Case Presentation: We describe a patient who presented with hemiparesia. He had undergone coronary angiography on his right and left coronary arteries as well as his left ventricle (LV) via the radial artery access 10 days earlier using a 6-French Tiger catheter. Transthoracic echocardiography showed a large (36 × 25 mm) inhomogeneous mobile mass attached to the apicoseptal LV segment. His serum protein S was low (60% [normal = 77 - 140%]), while his protein C was normal and lupus anticoagulant was negative. During hospitalization, he developed severe abdominal pain, for which mesenteric ischemia was diagnosed. First, he underwent surgery for the resection of the infarcted intestinal segments. Then cardiac surgery was done to remove the mass. The mass was diagnosed as a thrombus. After the surgery, the general condition of the patient deteriorated and blood culture showed acinetobacter septicemia. Finally, he died due to sepsis. A review of his coronary angiography revealed that after the contrast media had left the LV, there was still dye at the contact point between the tip of the catheter and the LV, which was compatible with the location of thrombus formation. Conclusions: Trauma induced by the tip of the catheter at the contact location with the LV wall in a patient with mild hypercoagulable state accounted for intracardiac thrombosis formation and its embolization to the brain and intestines.","PeriodicalId":429543,"journal":{"name":"Archives of Cardiovascular Imaging","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114998638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objectives: In this study, we used VVI to evaluate left ventricular (LV) main torsional parameters in non-ischemic dilated cardiomyopathy (DCM) patients in compared with normal subjects. Patients and Methods: Twenty-six DCM patients and Twenty-four normal subjects were assessed. Echocardiographic images of the short axis apical and basal views of LV were processed by VVI software to measure peak rotation degrees and also peak rotation rates in systole. LV twist was well-defined as the net difference between apical and basal rotation values and also LV torsion was considered as LV twist divided by left ventricular diastolic longitudinal length. In addition, peak untwisting value and untwisting rate were measured in diastole too. Results: LV twist value (5.54 ± 1.94° in DCM VS. 11.5 ± 2.45° in control group) and also LV torsion (0.71 ± 0.28°/cm in DCM VS. 1.53 ± 0.42°/cm in control group) were significantly decreased in DCM patients compared with normal group (P < 0.001 for both); also, the twisting rate was notably lower in DCM vs. control (38.68 ± 14.43°/s in DCM vs. 75.88 ± 17.25°/s in control; P < 0.001) and also untwisting rate (36.28 ± 13.48°/s in DCM vs. -73.79 ± 24.45°/s in control; P < 0.001), However normalization of these times for systolic duration or LV length creates different values. Conclusions: LV twist, torsion and untwist and also rate of them are significantly impaired in DCM and this impairment is well-related to LV global systolic and diastolic dysfunction.

Objectives: This is a report on echocardiographic findings in heart transplantation (HTx) patients in their first 5 postoperative months. Patients and Methods: Twenty patients undergoing HTx between September 2009 and July 2010 whose clinical and echocardiographic findings had been registered monthly for 5 months after HTx were enrolled. Results: Eleven males and five females at a mean age of 33 years [range = 17-58 years] were enrolled in the study. The mean of the left ventricular ejection fraction (LVEF) was 52 ± 8.2 % and 58 ± 2.5 % on the first day and at 5 months after HTx, respectively. There was no LV enlargement at 5 months' follow-up. The right ventricle (RV) was mildly enlarged, but the reduced baseline RV function showed improvement at the 5th postoperative month (mean TAPSE was 11.7 ± 3.3 mm on the first post-HTx day versus 17.2 ± 6.3 mm after 5 months; P < 0.005). The pulmonary arterial pressure was slightly elevated at baseline, and it showed no significant decrease 5 months after HTx. More than 90% of the cases showed only mild tricuspid regurgitation at 5 months' follow-up. The tissue Doppler imaging-derived velocities of the medial and lateral mitral annuli and the tricuspid annulus demonstrated a gradual increment during the follow-up and reached their highest value at 5 months' follow-up. Conclusions: The cardiac grafts at 5 months' post-HTx follow-up were characterized by normal LV dimensions and EF. Also, RV dysfunction and tricuspid regurgitation were frequent findings, but they were not associated with the clinical signs of congestive heart failure, morbidity, and mortality in the majority of our patients.","PeriodicalId":429543,"journal":{"name":"Archives of Cardiovascular Imaging","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129956478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
