Rheumatic heart disease is the most common cause of mitral valve stenosis. Left atrial appendage thrombus is associated with mitral stenosis, but in rare cases the thrombus can extend to the left atrial cavity. We present a case of a severe rheumatic mitral stenosis and associated large left atrial thrombus, with embolic sequelae.

Objectives: Systolic and diastolic dysfunctions are related to adverse clinical outcomes in patients with sinus rhythm. The aim of this study was to clarify the prognostic significance of systolic and diastolic dysfunctions in patients with chronic persistent atrial fibrillation (AF). Methods: We evaluated data for 114 consecutive patients with chronic AF who underwent measurement of LVEDP at our hospital between 1 March 2011 and 31 December 2014. In total, 114 consecutive patients with chronic AF were divided into two groups according to the left ventricular ejection fraction (LVEF): LVEF < 50 (reduced ejection fraction, REF group) and LVEF ≥50 (preserved EF, PEF group). The PEF group was further divided into two subgroups according to the left ventricular end-diastolic filling pressure (LVEDP): LVEDP >15 mmHg and LVEDP ≤ 15 mmHg. The 3-year clinical outcomes were compared between the PEF and REF groups and the LVEDP ≥15 mmHg and LVEDP <15 mmHg groups. Results: During the 3-year follow-up period, the rate of heart failure (HF) hospitalisation and incidence of AF with rapid ventricular rhythm (RVR) were higher in the REF group than in the PEF group. Multivariate analysis revealed that REF was the only significant predictor of HF hospitalisation (hazard ratio, 4.71; 95% confidence interval, 1.48–15.02; p=0.009). Conclusions: Our observations during a mid-term follow-up period revealed that systolic dysfunction could be an important predictor of HF hospitalisation in patients with AF. However, elevated LVEDP may not be associated with mid-term adverse clinical outcomes in patients without systolic dysfunction.

BACKGROUND: Systemic thromboembolism is a known complication of rheumatic mitral stenosis (RMS) in sinus rhythm (SR). Left atrial appendage (LAA), the commonest site of thrombus formation is usually hypocontractile (inactive) in such patients. We aimed to study the prevalence of LAA inactivity (LAAI) in severe RMS and assess its independent predictors. METHODS: The study population consisted of 100 patients of severe RMS in sinus rhythm. Transthoracic and transesophageal echocardiography were done to assess LAA contractile function. Patients with LAA-peak emptying velocity <25 cm/sec were defined as having LAAI. RESULTS: The mean age of study subjects was 31.66±8.69 years and 56% were females. 73% patients had LAAI (Group A), while remaining 27% had normal LAA function (Group B). Mitral-valve area (MVA) and lateral annulus systolic velocity (Sa-wave) were significantly lower while mean pressure gradient across mitral valve (MGMV) and serum fibrinogen were significantly higher (all p-values <0.001) in group A patients. On multivariate regression analysis, MGMV (p<0.001), Sa-wave (p=0.02) and serum fibrinogen (p=0.005) were independent predictors of LAAI. Optimal cut-off values of MGMV, Sa-wave and serum fibrinogen for predicting LAAI were 11.5mmHg, 6.8cm/sec and 300mg/dL respectively.67(90.55%) patients in group A compared to 13(48.1%) in group B had LA/LAA smoke. LAAI was the only independent predictor of left atrium (LA)/LAA smoke and associated thrombus. CONCLUSION: There is high prevalence of LAAI in patients of severe MS in SR. MGMV, Sa-wave and serum fibrinogen levels are independent predictors of LAAI. LAAI is an independent predictor of LA/LAA smoke and associated thrombus.

Primary cardiac tumors are extremely rare.Most primary tumors are benign,and malignant tumors comprise about 15%1.Angiosarcoma is the most common type of primary cardiac malignant tumors.Compared with the left atrium or ventricle,the tumor prefer to occur in the right atrium or ventricle,especially the right atrium.In this case report,we present the case of a 32-year-old female with cardiac angiosarcoma primary to the right atrial appendage(RAA).

An 86-year-old man with end-stage renal disease on hemodialysis with an arteriovenous fistula in his left upper extremity presented to his hemodialysis session with thrombosis of his arteriovenous fistula. The patient underwent surgical thrombectomy. The patient later showed evidence of peripheral embolization and livedo reticularis. Transthoracic and transesophageal echocardiograms revealed a large thrombus (5x2 cm) in the left atrium prolapsing to the right atrium via a patent foramen ovale and another thrombus (white arrow) adherent to the apical wall of the right ventricle. The thrombus in the left atrium was intermittently crossing the mitral valve and entering the left ventricle.

Objective: Arterial stiffness refers to arterial wall rigidity, particularly in central vessels, and is an independent predictor of cardiovascular disease. 25-Hydroxy (OH) vitamin D has beneficial effects on blood pressure, vascular endothelial function, and arterial stiffness. Therefore, we aimed to elucidate the role of 25-OH vitamin D deficiency in arterial stiffness development and its relationship with arterial stiffness in healthy children. Methods: This study included 80 patients with low levels of 25-OH vitamin D and 40 healthy control. The study participants were then divided into three groups: group 1 consisted of patients with a deficient 25-OH D level of < 19.9 ng/mL, group 2 with an insufficient 25-OH D level between 20-29.9 ng/mL; group 3 were considered control group with a sufficient serum 25-OH vitamin D level of ≥30 ng/mL. Aortic strain, distensibility, stiffness index, and standard left ventricular measurements were calculated using M-mode echocardiographic data. Results: Left ventricular mass index (LVMI) and interventricular septal diastolic thickness (IVSTd) appeared to increase in group 1 compared to groups 2 and 3. Aortic strain and distensibility were significantly decreased in group 1, whereas aortic stiffness index and elastic modulus were significantly increased. The aortic stiffness index was negatively correlated with serum 25-OH vitamin D levels; however, aortic strain, aortic distensibility, and LVMI were positively correlated. Conclusions: Our study results revealed a significant relationship between 25-OH vitamin D levels indicative of a deficiency and aortic stiffness. We suggest that arterial stiffness may also occur in healthy children with a 25-OH vitamin D deficiency.

In this report, we present a rare case of severe mitral regurgitation due to isolated mitral valve chordal rupture without valve leaflet prolapse in a patient with Fabry cardiomyopathy. This finding could be due to subvalvular apparatus storage of glycosphingolipids rather than fibro-elastic deficiency, underlying how close cardiological follow-up of Fabry patients must be comprehensive and not only focused on left ventricular hypertrophy and arrhythmias. We feel that our finding could be of interest for the readership of your Journal.

Background: We aim to investigate prognostic effects of carotid strain (CS) and strain rate (CSR) in hypertension. Methods: We prospectively recruited 120 patients being treated for hypertension (65.8 ± 11.8 years, 58% male) in this observational study. Peak circumferential CS and peak CSR after ejection were identified using two-dimensional speckle tracking ultrasound. Major cardiovascular events were any admission for stroke, acute coronary syndrome, and heart failure. Results: After a mean follow-up period of 63.6 ± 14.5 months, 14 (12%) patients had cardiovascular events. Age (75.3 ± 9.2 vs. 64.6 ± 11.6 years; p = 0.001), systolic blood pressure (131.8 ± 15.5 vs. 143.1 ± 16.6 mmHg; p = 0.021), diastolic blood pressure (74.6 ±11.4 vs. 82.1 ± 12.2 mmHg; p = 0.039), use of diuretics (71 vs. 92 %; p = 0.014), carotid CS (2.17 ± 1.02 vs. 3.28 ± 1.14 %; p = 0.001), and CSR (0.28 ± 0.17 vs. 0.51 ± 0.18 1/s; p <0.001) were significantly different between the patients who did and did not reach the end-points. Multivariate Cox regression analysis controlling for age, systolic blood pressure, diastolic blood pressure, and use of diuretics showed that CS (HR 0.425, 95%CI 0.223-0.811, p = 0.009) and CSR (HR 0.001, 95%CI 0.000-0.072, p = 0.001) were independent predictors for cardiovascular events. Conclusion: In conclusions, decreased CS and CSR were associated with cardiovascular events in hypertension.

Background: Because transcatheter closure of patent foramen ovale (PFO) has become effective for preventing cryptogenic stroke (CS), it is necessary to determine high-risk PFO associated with CS. This study aimed to clarify the importance of direct right-to-left (RL) shunt through the PFO for identifying high-risk PFO. Methods: We analyzed 137 patients with and without CS who were confirmed to have PFO. The timing of RL shunt through the PFO was evaluated by cardiac cycles after right atrium (RA) opacification on saline contrast transesophageal echocardiography. Direct RL shunt was defined as microbubbles crossing the PFO before and at the same time of RA opacification. Results: Cardiac cycles of microbubbles crossing the PFO were shorter in patients with CS than in those without CS (2.0 ± 2.2 vs. 0.5 ± 1.1, P < .01). Direct RL shunt was more frequently observed in patients with CS than in those without CS (77% vs. 29%, P < .01), with a sensitivity of 79% and a specificity of 71% for the association with CS. Multivariate analysis revealed that direct RL shunt was related to atrial septal aneurysm and low-angle PFO. Regarding functional features of PFO, the detection rate of CS was 50% for large RL shunt alone, and was increased to 83% when direct RL shunt was added. Conclusion: Direct RL shunt was associated with CS and had the incremental value in detecting PFO associated with CS for large RL shunt. The timing of RL shunt can be valuable for identifying high-risk PFO.

Spontaneous pseudoaneurysm of the aortic arch is an exceptionally rare and potentially life-threatening condition.Diagnosis of pseudoaneurysms of the aortic arch mainly depends on imaging examinations.Contrast-enhanced echocardiography, as a non-invasive, bed-side and radiation-free tool, plays an important role in the rapid diagnosis and postoperative follow-up of pseudoaneurysms of the aortic arch.

Double Inlet Left Ventricle through a common AV valve is a rare type of functionally univentricular heart. We report a fetus with double inlet left ventricle with discordant ventriculo-arterial connection and pulmonary atresia. The anatomy was readily apparent on three dimensional rendering by spatio-temporal imaging correlation technique(STIC)

Objective: Predicting postoperative atrial fibrillation (PoAF) in the preoperative period will provide a serious advantage in preventing the morbidity and mortality associated with this arrhythmia and in planning the treatment. In this study, we investigated the value of atrial electromechanical delay (AEMD) in predicting the development of PoAF. Methods: A total of 93 patients who underwent isolated coronary artery bypass grafting (CABG) operation were included in this prospective study. Patients’ demographic characteristics, laboratory parameters, echocardiographic data, and AEMD durations that could be measured by the co-use of electrocardiography and echocardiography were recorded. The patients at sinus rhythm during the postoperative period were identified as “Group 1”, and those who developed PoAF were identified as “Group 2”. Results: PoAF incidence was 26.88% (n=25). Left ventricle (LV) lateral AEMD, LV medial AEMD, right ventricle lateral AEMD, and left atrium (LA) lateral AEMD durations of Group 2 were significantly higher than Group 1 (p<0.001, p=0.004, p=0.004, p<0.001; respectively). In Univariate Logistic Regression Analysis, the age, hypertension, LA maximum volume, LA lateral AEMD and pulmonary artery pressure were significantly associated with PoAF development (p=0.01, p=0.004, p=0.004, p=0.001, p=0.01; respectively). However, only LA lateral AEMD was found as an independent predictive factor for the development of PoAF in the Multivariate Logistic Regression Analysis (OR:1.03, 95% CI:1,001-1.06, p=0.04). AUC was 0.741 for LA lateral AEMD in ROC Curve Analysis (95% CI:0.633-0.849, p<0.001). Conclusions: The development of PoAF can be predicted by AEMD durations measured in the preoperative period in patients undergoing isolated CABG.

BACKGROUND. Mitral valve (MV) repair with MitraClip system is a safe treatment option for high-risk patients with significant mitral regurgitation (MR). We aimed to characterize, by three-dimensional echocardiography (3D-E), changes occurring in MV after implantation of third generation MitraClip XTR device, with specific reference to the underlying MR mechanism (functional vs. degenerative, FMR vs DMR). METHODS. We prospectively enrolled 59 patients, who underwent intra-procedural 3D-E before and after device deployment. Three-D datasets were analysed off-line, using a dedicated semiautomatic software, to obtain parametric quantification of mitral anatomy. RESULTS. Post-procedural MR of mild or lesser degree was achieved in 40 patients (68%), with no differences between FMR and DMR (p 0.9). After MitraClip XTR implantation, the FMR group experienced an immediate annular resizing, with reduction of antero-posterior diameter (p 0.024) and sphericity index (p 0.017), next to a recovery of physiological saddle-shape, defined by lower non-planar angle (p ≤0.001) and higher annulus height to commissural width ratio (p ≤0.001). On the opposite, the DMR group revealed a significant decrease of maximum annular velocity (p 0.027), addressing a mechanic effect of the device deployment. Finally, baseline anterior mitral leaflet angle was found as the strongest independent predictor of acute procedural result (OR 0.91, [CI 0.84-0.99], p = 0.030). CONCLUSIONS. MitraClip XTR implantation acts in restoring the original mitral geometry, with distinctive effects according to MR mechanism. Three-D parametric quantification of MV sheds new light on changes occurring in the valvular apparatus, and helps identifying possible new predictors of acute procedural success.

Methods The study included 59 patients with normal fetal heart structure, blood flow, and heart rhythm (fetal abnormality-negative group) and 50 patients with abnormal fetal heart structure, blood flow, and/or heart rhythm (fetal abnormality-positive group). aCMQ was performed in both groups to obtain left and right ventricular endocardial global longitudinal strain (GLSendo), mid-myocardial global longitudinal strain (GLSmid), and epicardial global longitudinal strain (GLSepi). Parameters between the two groups were compared and correlation analyses performed. A deformation analysis was performed by two trained observers, and reproducibility was assessed. Results The fetal left ventricular and right ventricular global longitudinal strain (LV-GLS and RV-GLS, respectively) decreased in a gradient from the endocardium to the epicardium. LV-GLS and RV-GLS of all myocardial layers were lower in the fetal abnormality-positive than -negative group (all P<0.05). Correlation analysis showed that neither LV-GLS nor RV-GLS was significantly correlated with gestational age in the fetal abnormality-negative group (all P>0.05), whereas left ventricular GLSendo, GLSmid, and GLSepi were negatively correlated with gestational age in the fetal abnormality-positive group (r=−0.39 to −0.44, all P<0.05). Repeatability testing showed that the inter-observer and intra-observer intraclass correlation coefficients for LV-GLS and RV-GLS in each myocardial layer were >0.75 (all P<0.001). Conclusions As a new speckle tracking echocardiography tool, aCMQ has feasibility and repeatability in evaluating myocardial deformation of the fetal ventricle. This technique might provide helpful information on ventricular myocardial deformation in fetal hearts with abnormal structure or rhythm for clinical guidance in pregnancy.

Aortico-left ventricular tunnel (ALVT) is a rare congenital cardiac anomaly and constitues of less than 0.1% of all congenital cardiac defects (1). ALVT is described as an abnormal connection between the ascending aorta and the left ventricul which originates commonly above the right sinus of valsalva. Most patients are diagnosed with an ALVT during early infancy (2). Although transthoracic echocardiography (TTE) is more effective in diagnosis of ALVT, misdiagnosis rate was 17.1% (3). Sinus of valsalva aneurysm (SVA) is frequently confused with ALVT (3). We report a term female newborn with SVA in echocardiographic examination but in surgery she was diagnosed with ALVT.

Kawasaki disease (KD) is a self-limited vasculitis with significant morbidity and even mortality if not treated early. The diagnosis and timely treatment in children younger than 3 months is challenging, most of them have an incomplete or atypical presentation. Coronary artery abnormalities are frequent in this type of patients. We present a 6-week-old female infant with Kawasaki disease who developed a giant coronary aneurysm. The timely diagnosis and promptly treatment as well as the echocardiographic and multimodality follow-up allowed us to improve our clinical approach and management.

Abstract A mediastinal carcinoid is a low-grade malignant tumor, which has low risk of metastasis, and cardiac metastasis is even rarer. When a patient has cardiac metastasis, the primary carcinoid is usually widely metastasized. In this case report, we presented occurrence of isolated left-sided cardiac metastases ten years after surgical removal of left anterior superior mediastinal carcinoid.

Prevalence of primary coronary cameral fistula (CCF) is extremely rare, especially for CCF with the drainage site into the left ventricle. We describe a 45-year-old patient with chest tightness in whom a giant aneurysm associated with proximal right coronary artery (RCA), and the distal end of RCA terminated into the left ventricle through a fistula was discovered by echocardiography. Dual-source computer tomography revealed the CCF-related giant RCA aneurysm. The drainage site and coexistent abnormality could not be visualized well by coronary artery angiography because of the severely diluted contrast medium into the aneurysm. Finally, the patient received surgical treatment and is asymptomatic now.
