BACKGROUND: IT is well known that serum N-terminal pro brain natriuretic peptide (NT-proBNP) tends to elevate in acute phase of Kawasaki disease (KD), but the cause of NT-proBNP elevation has not been clarified. Our previous study revealed that cardiac function evaluated by two-dimensional echocardiography (2D-E) such as ejection fraction (EF) was normal. However, cardiac function evaluated by 2D-E does not reflect subtle change of cardiac dysfunction and the relation has still been controversial...

AIM: To study the changes of mitral valve (MV) in patients with nonvalvular atrial fibrillation (NVAF)-related mitral regurgitation (MR) and the relationship between MV parameters and the enlarged left atrium (LA). MATERIALS AND METHODS: A total of 43 patients with NVAF were divided into two groups: (1) the MR1 group with mild MR and (2) the MR2 group with moderate-to-severe MR. Real time 3D transesophageal echocardiography (TEE) was performed to detect the structure of MV...

The development of an aorto-right ventricular fistula is a rare complication of cardiac surgery. The most common treatment is surgical closure of the fistula, but percutaneous closure of the fistula has become an attractive alternative option. We present a case of successful utilization of live/real time three/four-dimensional transoesophageal echocardiography (3/4DTEE) to select the correct device size for percutaneous closure of an adult patient presenting with an aorto-right ventricular (AO-RV) fistula following aortic valve replacement...

Mitral stenosis is a uncommon valvular lesion in the developed countries. Noninvasive evaluation is the first-line modality for assessment of mitral stenosis, however the noninvasive methods may have limitations in certain cases. Invasive hemodynamics can be used as adjunct tool for assessment of mitral stenosis in such difficult cases. Mitral valve using three-dimensional planimetry is a promising technique for assessment of mitral stenosis.

Left Atrial Appendage (LAA) is the most contractile part of Left atrium. It is also the most frequent place for thrombus formation that may lead to disastrous consequences. Complete trasoesophageal echocardiography examination always includes assessing LAA but sometimes unusually placed pectinate muscle, which is a normal structure may give baffling shadow that can only be interpreted correctly by Real time 3D echocardiography.

Treatment decision for coronary artery disease (CAD) is based on both morphological and functional information. Image fusion of coronary computed tomography angiography (CCTA) and three-dimensional echocardiography (3DE) could combine morphology and function into a single image to facilitate diagnosis. Three semiautomatic feature-based methods for CCTA/3DE registration were implemented and applied on CAD patients. Methods were verified and compared using landmarks manually identified by a cardiologist. All methods were found feasible for CCTA/3DE fusion...

Assessment of right ventricular (RV) function using conventional echocardiography might be inadequate as the radial motion of the RV free wall is often neglected. Our aim was to quantify the longitudinal and the radial components of RV function using three-dimensional (3D) echocardiography in heart transplant (HTX) recipients. 51 HTX patients in stable cardiovascular condition without history of relevant rejection episode or chronic allograft vasculopathy and 30 healthy volunteers were enrolled. RV end-diastolic (EDV) volume and total ejection fraction (TEF) were measured by 3D echocardiography...

Calpainopathy or limb-girdle muscular dystrophy type 2A (LGMD2A) is the most common type of autosomal recessive limb-girdle muscular dystrophies. The disease is caused by mutations in the CAPN3 gene encoding calpain, a protein involved in muscle membrane remodeling and repair. This paper gives an overview of the genetic background, clinical course, and diagnosis of the disease, and presents the first case of calpainopathy in which cardiac deformation mechanics was investigated. Three-dimensional speckle-tracking echocardiography (3DSTE) demonstrated reduced left ventricular (LV) strains and increased LV apical rotation and twist, suggestive of asymptomatic subclinical LV dysfunction...

Background - Poor fitness in middle age is a risk factor for heart failure, particularly heart failure with a preserved ejection fraction. The development of heart failure with a preserved ejection fraction is likely mediated through increased left ventricular (LV) stiffness, a consequence of sedentary aging. In a prospective, parallel group, randomized controlled trial, we examined the effect of 2 years of supervised highintensity exercise training on LV stiffness. Methods - Sixty-one (48% male) healthy, sedentary, middle-aged participants (53±5 years) were randomly assigned to either 2 years of exercise training (n=34) or attention control (control; n=27)...

BACKGROUND: Tricuspid regurgitation (TR) is an important risk factor for morbidity and mortality in hypoplastic left heart syndrome (HLHS), yet the evolution of tricuspid valve (TV) dysfunction in HLHS is poorly understood. This study sought to examine changes in TV function in HLHS between the first two stages of surgical palliation and to determine the mechanism of TR at the time of stage two surgery-bidirectional cavopulmonary anastomosis (BCPA). METHODS: We prospectively investigated 44 infants at two time points-prior to Norwood-Sano (T1 - median age 5...

Congenital heart disease (CHD), the most common congenital malformation, is associated with adverse outcome. Development of fetal echocardiography has made prenatal diagnosis of CHD a reality, and in the process revolutionized its management. This historical review briefly narrates this development over the decades focusing on the emergence of the primary modalities of fetal echocardiography comprised of the time-motion mode, two-dimensional B-mode, spectral Doppler, color Doppler, and three- and four-dimensional cardiac imaging...

Hammock mitral valve (MV), also known as anomalous mitral arcade, is a rare congenital anomaly. We report a case of a 10-month-old child who presented with congestive heart failure and was found to have severe mitral stenosis (MS) secondary to a hammock MV anomaly. Detailed advanced imaging with cardiac MRI and three-dimensional (3D) echocardiography favorably navigated a customized valve-sparing surgical reconstruction of the congenitally abnormal MV. Repair of a hammock MV is technically difficult with a guarded prognosis...

Cardiac transthyretin-related (ATTR) amyloidosis is a severe cardiomyopathy for which therapeutic approaches are currently under development. Because non-invasive imaging techniques such as cardiac magnetic resonance imaging and echocardiography are non-specific, the diagnosis of ATTR amyloidosis is still based on myocardial biopsy. Thus, diagnosis of ATTR amyloidosis is difficult in patients refusing myocardial biopsy. Furthermore, myocardial biopsy does not allow 3D-mapping and quantification of myocardial ATTR amyloid...

BACKGROUND: Pediatric heart transplant recipients are at risk for increased left ventricular (LV) diastolic stiffness. However, the noninvasive evaluation of LV stiffness has remained elusive in this population. The objective of this study was to compare novel echocardiographic measures of LV diastolic stiffness versus gold-standard measures derived from pressure-volume loop (PVL) analysis in pediatric heart transplant recipients. METHODS: Patients undergoing left heart catheterization were prospectively enrolled...
