Background: Accessory mitral valve tissue (AMVT) is an extremely rare causes left ventricular outflow tract (LVOT) obstruction and is usually incidentally detected in childhood. It is often associated with other cardiac and vascular congenital malformations., Case Presentation: In this case, we present a 15-year-old girl was diagnosed with AMVT by transesophageal echocardiography, resulting in LVOT obstruction during systole. Interestingly enough, the patient's accessory mitral valve remained undetected for years until he became symptomatic for wide ASD. Successful closure of the ASD with resection of the AMVT was performed with a transaortic approach. The patient was hemodynamically stable postoperatively. There were no abnormalities in the mitral valves and LVOT., Conclusion: It was also unusual to see AMVT with ASD instead of other frequently associated other congenital anomalies. Accessory mitral valve should be considered a rare but important cause of left ventricular outflow tract obstruction in childhood., (© 2022 Wiley Periodicals LLC.)

Pacemaker-associated superior vena cava (SVC) syndrome is increasingly recognized as a nonmalignant type of SVC syndrome. Computed tomographic (CT) angiography is the first choice of imaging for diagnosis but in some cases there is discrepancy between the clinical findings and CT images. In this report we present the role of contrast study with transesophageal echocardiography in a patient with suspicion of SVC syndrome but inconclusive CT findings., (© 2022 Wiley Periodicals LLC.)

Aim: Doppler echocardiography has become the standard imaging modality for diastolic function and provides pathophysiological insight into systolic and diastolic heart failure. In this study, we aimed to obtain normal echocardiographic Doppler parameters of healthy Turkish population., Methods: Among 31 collaborating institutions from all regions of Turkey, 1154 healthy volunteers were enrolled in this study. Predefined protocols were used for all participants during echocardiographic examination and The American Society of Echocardiography and European Association of Cardiovascular Imaging recommendations were used for echocardiographic Doppler measurements., Results: A total of 967 healthy participants were enrolled in this study after applying exclusion criteria. Echocardiographic examination was obtained from all subjects following predefined protocols. Mitral E wave velocity and E/A ratio were higher in females and decreased progressively in advancing ages. E wave deceleration time and A wave velocity were increased with aging. Assessment of tissue Doppler velocities showed that left ventricular lateral e', septal e', and septal s' were higher in younger subjects and in females. E/e' ratio was increased progressively with advancing decades. Right ventricular e' and s' were decreased but a' was increased with increasing age. Septal e' lower than 8 cm/s was 1.9% in the fifth decade and 13.7% in ages older than 50 years. The E/e' ratio greater than 15 (and also 13) was not found., Conclusion: This study, for the first time, provides echocardiographic reference ranges for normal cardiac Doppler data in healthy Turkish population which will be useful in routine clinical practice as well as in future clinical trials., (© 2020 Wiley Periodicals LLC.)

Long-standing left-to-right shunting across a patent ductus arteriosus (PDA) can result in Eisenmenger syndrome. In this report, we present echocardiographic findings of a 27-year-old female patient with pulmonary hypertension. In diagnostic work-up especially Doppler findings of the pulmonary artery suggested the presence of a reversed PDA as a cause of pulmonary hypertension. The diagnosis was confirmed by contrast study and computed tomography., (© 2020 Wiley Periodicals, Inc.)

A sinus of Valsalva aneurysm is a rare cardiac anomaly, and it is usually clinically silent. However, it may lead to symptoms when it compresses adjacent cardiac structures. Herein, we would like to report a 45-year-old lady with exertional dyspnea who was first diagnosed with having a cystic cardiac mass on transthoracic echocardiogram. Then, transesophageal echocardiogram and cardiac computed tomography revealed an unruptured aneurysm of noncoronary sinus of Valsalva., (© 2020 Wiley Periodicals, Inc.)

Coronary sinus atrial septal defect (ASD) is a rare congenital cardiac anomaly, which might be difficult to diagnose. In this report, we describe a patient with small secundum ASDs and an associated large coronary sinus ASD, which had been missed at initial evaluation. The diagnosis of coronary sinus ASD was established by using transesophageal echocardiography after percutaneous closure of a small secundum ASD at another center. Patient underwent corrective surgery., (© 2019 Wiley Periodicals, Inc.)

Objective: Cardiac dysfunction is a well-known consequence of diabetes mellitus. This study was designed to assess whether type 1 diabetic children and adolescents with good metabolic control have early echocardiographic signs of subclinical left ventricular dysfunction and whether diabetes duration has any influence, using conventional and nonconventional echocardiographic tools., Methods: A total of 100 patients with type 1 diabetes mellitus and 80 gender- and age-matched healthy controls were included. The cases underwent standard conventional transthoracic echocardiography, tissue Doppler imaging, and two-dimensional speckle tracking echocardiography. None of the diabetic patients had signs of renal, retinal, or neurological complications of the disease, and all were good metabolic control (mean HbA 1c <7.5%)., Results: There was no difference among groups in relation to age, sex, body mass index, and blood pressure. Conventional echocardiographic parameters were similar between diabetic and nondiabetic subjects except increased mitral valve peak A-wave and significantly lower mitral E/A ratio in diabetics. Diabetic patients had more advanced diastolic dysfunction with TDI analysis. In the diabetic group, left ventricular global longitudinal, circumferential, and radial strain and strain rate were significantly lower compared with the controls. There was a positive correlation between diabetes duration and cardiac dysfunction., Conclusion: The results of this study showed that the diabetic children and adolescents with good metabolic control had diastolic dysfunction when assessed with either conventional or tissue Doppler echocardiography. Also diabetic patients had subclinical LV systolic dysfunction with a normal LVEF which can be detected with 2D speckle tracking echocardiography., (© 2017 Wiley Periodicals, Inc.)

Interrupted aorta is a very rare heart defect in which there is a gap between the ascending and the descending thoracic aorta. It is usually associated with other cardiac anomalies, including ventricular septal defect, ductus arteriosus, and truncus arteriosus. Severe cases present with serious complications such as hypertension, heart failure, or intracranial hemorrhage. Neurological complications are very rare form of presentation and commonly associated with intracranial aneurysms. We have reported a case of interrupted aorta who presented with transient ischemic attack due to thrombus formation in the interrupted segment of the aorta., (© 2017, Wiley Periodicals, Inc.)

Myocardial clefts are defined as narrow, deep blood-filled invaginations within the left ventricular myocardium. They occur in hypertrophic cardiomyopathy patients with different frequency and represent a distinctive morphological expression of hypertrophic cardiomyopathy. Although two-dimensional transthoracic echocardiography is able to detect myocardial clefts in some cases, cardiovascular magnetic resonance imaging with its high spatial resolution can detect myocardial clefts not visualized with echocardiography. In this report, we represent multimodality imaging of a septal myocardial cleft in a hypertrophic cardiomyopathy patient., (© 2016, Wiley Periodicals, Inc.)

A 59-year-old man who was admitted to the emergency department with new and spontaneous onset of fatigue, dyspnea, and palpitations. There was neither a history of trauma, chest pain, nor infection. Transthoracic two- and three-dimensional echocardiography and computer tomography demonstrated sinus of Valsalva aneurysm rupture dissecting interatrial septum and leading to a huge thrombus formation in it. The diagnosis with multimodality imaging performed within hours, and urgent surgery saved the patient's life., (© 2016, Wiley Periodicals, Inc.)

Background: There is some evidence suggesting increased risk of atrial fibrillation (AF) in patients with celiac disease (CD). Impaired left atrial function plays a significant role in the development of AF. This study aimed at assessing the electrical and mechanical functions of the left atrium in patients with CD., Methods: A total of 71 patients with biopsy-proven, antibody-positive CD and 52 age-matched healthy controls were included in this prospective study. P-wave dispersion (PWD) was measured to assess the electrical functions of the left atrium through the use of surface electrocardiography. A tissue Doppler echocardiography was performed to determine the atrial conduction and electromechanical delay (EMD) time. To evaluate the mechanical functions of the left atrium, maximum, minimum, and presystolic atrial volumes were estimated to calculate the contractile, conduit, and reservoir functions., Results: In terms of transthoracic echocardiographic parameters, CD and control subjects were not significantly different. However, as compared to controls, patients with CD had significantly increased PWD (median 52 ms [interquartile range 46-58 ms] vs. 38 [36-40], P < 0.001). Also, significantly higher interatrial (49 ms [32-60] vs. 26 ms [22-28], P < 0.001), intra-left atrial (26 ms [17-44] vs. 14 ms [12-18], P < 0.001), and intra-right atrial (15 ms [8-22] vs. 10 ms [8-14], P < 0.001) EMD was found among CD subjects than controls. Despite an increase in the left atrial volume in patients with CD, conduit and reservoir functions were comparable., Conclusions: Although atrial mechanical functions are preserved in patients with CD, a slower electrical conduction was found, suggesting an increased risk of AF in this group of patients., (© 2015, Wiley Periodicals, Inc.)

Objectives: Children with Turner syndrome (TS) are at increased risk of cardiovascular disease (CVD), but associations with subclinical CVD are not well-characterized. The purpose of this study was to assess myocardial function using strain imaging (SI) by echocardiography in children with TS and without known CVD., Methods: The study included 48 children with TS aged 4-16 years and 20 healthy control children. Children with TS were excluded if they had a cardiac malformation, a decreased left ventricular (LV) systolic function, or any chronic disease. Each child had an echocardiographic examination with conventional echocardiography and one-dimensional longitudinal strain (1DST) echocardiography., Results: Septal and lateral systolic strain (S) and strain rate (SR) values, which are indicative of longitudinal myocardial function, were significantly decreased in TS patients. However, LV ejection fraction (LVEF) and LV fractional shortening (LVFS) was not significantly different between groups. LV mass index (LVMi), interventricular septum (IVS) thickness, LV posterior wall (LVPW) thickness, and left atrial (LA) diameter index were significantly higher in TS children compared to controls. Peak transmitral flow velocity in late diastole (peak A) was significantly higher, whereas peak transmitral flow velocity in early diastole (peak E), deceleration time (DT), and the ratio of early to late diastolic filling were significantly lower, in TS patients., Conclusion: Reduced LV systolic S and SR in children with TS may indicate early myocardial dysfunction before any detectable change in LVEF., (© 2013, Wiley Periodicals, Inc.)

Objectives: Left ventricular (LV) synchronous contraction is impaired in patients with hypertension (HT). The deleterious effects of HT on cardiovascular system are more evident in patients with nondipper HT than dippers. In this study, we aimed to investigate the effect of nondipping HT on LV systolic synchronicity compared with dippers and controls., Methods: One hundred patients with newly diagnosed essential HT and 50 normotensive subjects were enrolled in this study. The hypertensive patients were assigned 2 groups comprising 55 dippers and 45 nondippers. Each subject underwent a comprehensive transthoracic echocardiographic examination. The evaluation of systolic dyssynchrony was performed by tissue synchronization imaging, and the time to regional peak systolic tissue velocity (Ts) in LV was measured on the basis of 12 segmental models. The standard deviation (SD) of the 12 LV segments (Ts-SD-12) and maximal difference in Ts between any two of the 12 LV segments (Ts-12) were calculated., Results: Compared with the control group, the synchronicity indexes were significantly prolonged in the hypertensive patients. Furthermore, Ts-SD-12 and Ts-12 values were found to be significantly impaired in patients with nondipper HT, compared with dippers: Ts-SD-12 (38.1 ± 18.7 vs. 31.8 ± 15.4, P ≤ 0.001); Ts-12 (123.0 ± 50.6 vs. 98.4 ± 42.3, P ≤ 0.001). Stepwise multivariate logistic regression analysis revealed a significant negative association between LV dyssynchrony indices and percentage decline in BP level from day to night., Conclusion: Synchronous systolic contraction of LV is found to be significantly impaired in patients with nondipping circadian pattern of HT compared with dippers and the controls., (© 2013, Wiley Periodicals, Inc.)

Aim: In diabetes mellitus (DM) patients, left ventricular dysfunction is widely evaluated and established by conventional diagnostic methods, whereas right ventricular (RV) function is not as sufficiently evaluated. The aim of this study is to assess the preclinical effects of DM on RV function by using novel Tissue Doppler Imaging (TDI)-derived indices., Methods: The study included 96 patients with type II DM [60 with DM only and 36 patients with coexisting DM and hypertension (DMHT)] and 40 healthy controls. Conventional parameters and TDI-derived systolic velocities of tricuspid annulus [isovolumic myocardial acceleration (IVA), peak myocardial velocity during isovolumic contraction (IVV), peak systolic velocity during ejection period (Sa), RV Tei index] were measured., Results: TDI-derived RV IVA was significantly lower in both DM and DMHT patients compared to controls indicating subclinical impairment in RV systolic function in the study patients (P = 0,0001). However RV IVA was similar in DM and DMHT subgroup supporting RV systolic impairment in DM was independent from HT. In correlation analysis, RV IVA was significantly correlated with the existence of diabetic nephropathy (r =-0,38; P = 0,003), retinopathy (r =-0,35; P = 0,006), insulin resistance (r =-0,52; P = 0,0001)., Conclusions: Diabetes is associated with subclinical RV systolic dysfunction, regardless of coexisting hypertension. Tissue Doppler-derived IVA; is a novel, non-invasive parameter which may be used in early detection of RV systolic dysfunction in patients with DM., (© 2010, Wiley Periodicals, Inc.)

Infective endocarditis (IE) is rarely seen in pregnancy and puerperal period, and generally occurs in patients with preexisting heart disease or intravenous drug abuse. In this report, we describe a case of a 27-year-old patient with missed diagnosis of rheumatic heart disease and a moderate size patent ductus arteriosus, in whom multisite culture-negative IE/pulmonary endarteritis developed after uncomplicated vaginal delivery.

Cardiac papillary fibroelastoma (CPF) is a rare cardiac neoplasm predominantly affecting the cardiac valves. Although it is most commonly an incidental finding, it can result in life-threatening complications, such as coronary and cerebral embolism, acute valvular dysfunction, and sudden death. In this report, we describe a case of a patient with aortic valve papillary fibroelastoma, which presented with sudden vision loss due to branch retinal artery occlusion. To the best of our knowledge, this is the third case of CPF-related retinal artery embolism in English literature.

Right atrial aneurysm (RAA) is a very rare anomaly. Rarer still is its association with atrial septal defect (ASD). We reported a case of a 42-year-old woman with giant RRA and secundum type ASD detected by means of transthoracic echocardiography.

Left ventricular pseudoaneurysm is a false aneurysm, which results from a left ventricle rupture contained by adherent pericardium or scar tissue. The most common etiology of left ventricular pseudoaneurysm is acute myocardial infarction but one-third of pseudoaneurysms develop following surgery. We present a case report of a patient who developed a false aneurysm of the left ventricle 2 months following surgical repair of a left ventricular aneurysm with a concomitant coronary bypass.
