A 42-year-old female patient was referred our clinic for investigation of a history of acute retinal artery occlusion. Transthoracic echocardiography showed a cyst-like, mobile formation on posterior mitral valve leaflet. 2D and real time 3D transesophageal echocardiography showed a flexible circular mobile structure which was attached to posterior mitral valve leaflet. Echocardiographic appearance and morphological characteristics were suggestive of accessory mitral valve tissue.

Thoracic aortocaval fistula is a very rare cause of left to right shunt. Drainage of fistula into the superior vena cava (SVC) is very uncommon. Clinical symptoms depend on the size of the shunt. We report a rare case of an asymptomatic 27-year-old woman with congenital aortocaval fistula to the SVC with a small amount of left to right shunt that was considered for serial medical follow-up.

Anomalous origin of left coronary artery from pulmonary artery (ALCAPA) accounts for 0.4% of the congenital heart diseases. Comprehensive 2D and 3D transesophageal echocardiographic imaging of a well-collateralized subset of ALCAPA is described. A nonstandard short-axis view of both aorta and pulmonary arteries showed the origin of left coronary artery from the posterior sinus of the pulmonary artery and right coronary artery in its usual position. Pulse-wave interrogation of the coronary arteries showed the direction of flow in opposite directions...

Until recently, diagnosis of intramyocardial dissecting hematoma (IDH) was performed during necropsy or at surgery. During the recent years, echocardiography has permitted clinical suspicion, which usually needed confirmation with magnetic resonance imaging (MRI). In this study, we tried to define clinical and imaging features of IDH and predictors of mortality. We searched the literature for proven cases of IDH and analyzed them together with 2 of our cases. A total of 40 cases of IDH (2 our original and 38 literature cases) were included...

BACKGROUND AND AIM: QRS amplitude and duration are associated with increased left ventricular (LV) volume, mass and dysfunction. However, the diagnostic concordance between QRS measurements and LV morphology and function, as shown by Doppler echocardiography, is not well established. We investigated the relationships of QRS duration and amplitude with echocardiographic measurements of LV morphology and systolic and diastolic function in normal individuals. METHODS: Individuals without signs or symptoms of coronary artery disease or heart failure, who underwent clinical examination as a part of a cross-sectional survey for the prevalence of coronary risk factors, randomly selected from the population list in Caltanissetta, Italy, were included in the study...

Left atrial appendage mass can occasionally pose a serious challenge to physicians to identify the nature of the mass with the aid of imaging techniques. We present a case of 67-year-old man, who was evaluated for suspected left atria myxoma. Transesophageal echocardiography revealed a heterogeneous density originating from left atrial appendage, thought to be most consistent with a myxoma. Cardiac magnetic resonance imaging, uncharacteristically, gave an equivocal picture, suggesting the mass to be a myxoma on initial imaging and a thrombus with evidence of liquefaction necrosis following postcontrast enhancement...

AIMS: The clinical significance of papillary muscle hypertrophy and its electrocardiography (ECG) findings has not been fully elucidated. This study aimed to investigate the relationship between ECG findings and papillary muscle hypertrophy and to confirm the importance of papillary muscle measurements on transthoracic echocardiography (TTE). METHODS AND RESULTS: Of the 237 consecutive patients who showed left ventricular hypertrophy (LVH) pattern on a 12-lead ECG, TTE data were available for 101 patients...

BACKGROUND: Two-dimensional speckle tracking echocardiography is an emerging technique for analyzing cardiac function in newborns. Strain is a highly reliable and reproducible parameter, and reference values have been established for term and preterm newborns. Its implementation into clinical practice has been slow, partly due to lack of inter-vendor consistency. Our aim was to compare recent versions of Philips and Tomtec speckle tracking software for deformation and semiautomated volume and area measurements in neonatal intensive care patients...

BACKGROUND: Aortic prosthesis area (EOA) is computed by continuity equation from left ventricular (LV) stroke volume (SV) derived from LV outflow tract diameter (LVOTD ) or, when unmeasurable, from LV volumes (SVV ). There is evidence to suggest LVOT ellipticity and recommend 3D LVOT area (LVOTCSA ) adoption in aortic stenosis. We sought to evaluate if the same concept applies to supra-annular aortic prosthesis comparing SV and EOA derived from LVOTD (EOAD ) and from LVOTCSA (EOACSA )...

Shone's syndrome is a rare congenital anomaly defined as the presence of at least two of the following heart obstructions: a mitral supravalvular ring, a "parachute" mitral valve stenosis, subaortic stenosis, and aortic coarctation. A 58-year-old man presented with a mitral ring and a "parachute" mitral valve on two-dimensional transthoracic echocardiography, raising suspicion of Shone's syndrome. Three-dimensional transesophageal echocardiography revealed a subannular mitral ring inserted directly on the mitral leaflets, thus acting as a "valvar ring...

BACKGROUND: There is a paucity of investigation which demonstrates a predictor of mitral regurgitation (MR) worsened after aortic valve replacement (TAVR). AIM: The aim of this study was to identify the predictor of worsened MR after transcatheter TAVR. METHODS: We retrospectively studied a total of 209 patients with mild or less MR at baseline who underwent TAVR for the treatment of severe aortic stenosis with the balloon-expandable device...

BACKGROUND: Alteration in mitral valve morphology resulting from retrograde stiff wire entanglement sometimes causes hemodynamically significant acute mitral regurgitation (MR) during transfemoral transcatheter aortic valve replacement (TAVR). Little is known about the echocardiographic parameters related to hemodynamically significant acute MR. METHODS AND RESULTS: This study population consisted of 64 consecutive patients who underwent transfemoral TAVR. We defined hemodynamically significant acute MR as changes in the severity of MR with persistent hypotension (systolic blood pressure < 80-90 mm Hg or mean arterial pressure 30 mm Hg lower than baseline)...

AIMS: Neither two- nor three-dimensional (3D) planimetry of the mitral valve (MV) orifice takes the mitral commissures into account. Thus, if the commissures are not completely fused, the MV orifice will not be planar, and MV area (MVA) will be underestimated. The study aimed to validate a novel method for measurement of the MVA using a software that traces the MV orifice including the commissures. METHODS AND RESULTS: The study included 30 patients undergoing percutaneous balloon mitral valvuloplasty for severe rheumatic mitral stenosis...

BACKGROUND: Transcatheter heart valve thrombosis (THV-t) and endocarditis (THV-e) are relevant complications after transcatheter aortic valve implantation (TAVI). Transcatheter heart valve (THV) dysfunction definition is mostly based on Doppler (stenosis/regurgitation) without considering leaflets characteristics. PURPOSE: To evaluate the additional diagnostic value of leaflets echocardiographic features over Doppler when prosthetic valve complication is suspected...

The use of linear and convex transducers is usually reserved for ultrasound imaging of vessels, abdominal organs, and lungs. However, the use of these transducers may be extended for the evaluation of thoracic structures. We describe our experience with the use of linear and convex transducers in the evaluation of the retrosternal area, which is usually difficult to visualize by conventional echocardiography and so could provide improved diagnostic information in patients after cardiac surgery.

Transcatheter aortic valve implantation (TAVI) has revolutionized the treatment of elderly patients with symptomatic severe aortic valve stenosis. Among the possible TAVI complications, a rare one is the annular/left ventricular outflow tract rupture. We report a rare case of a late complex ventricular septal defect (VSD) following TAVI with a balloon-expandable prosthesis, conservatively managed. Our case demonstrates the role of 3D transthoracic echocardiography (3DTTE) in the accurate diagnosis of this TAVI complication and suggests that, in some cases, it can be used as an alternative to other diagnostic tools, such as transesophageal echocardiography, cardiac catheterization, and computed tomography...

AIM: To investigate myocardial deformation and function during treatment for Kawasaki disease (KD) in children. METHODS: We performed speckle tracking echocardiography (STE) and tissue Doppler imaging (TDI) in 15 children with KD and 15 healthy children during treatment for KD. STE was performed for longitudinal and circumferential strain (S) and strain rate (SR) at the left ventricle (LV) and for longitudinal S and SR at the right ventricle (RV). TDI was performed at the base of interventricular septum (IVS), LV, and RV...
