BACKGROUND: Quantitative echocardiographic measurements of single ventricular (SV) function have not been incorporated into routine clinical practice. METHODS: A clinical protocol, which included quantitative measurements of SV deformation (global circumferential and longitudinal strain and strain rate), standard deviation of time to peak systolic strain, myocardial performance index (MPI), dP/dT from an atrioventricular valve regurgitant jet, and superior mesenteric artery resistance index, was instituted for all patients with a history of Fontan procedure undergoing echocardiography...

Left atrial appendage closure with the WATCHMAN device is an alternative to chronic oral anticoagulation for thromboembolic prophylaxis in atrial fibrillation patients. Left atrial device-related thrombus (DRT) has been described in the first year after implant with an incidence of ~6%. A 79-year-old man underwent WATCHMAN device placement in 2006. Routine protocol specified follow-up transesophageal echocardiograms (TEE) at 6 weeks, 6 months, and 1 year following implant showed no evidence for DRT or peri-device flow...

AIMS: The clinical implication of the inferior vena cava collapsibility index (IVCCI) has not been well evaluated in patients with various cardiovascular diseases. METHOD AND RESULTS: The relationships between clinical characteristics and echocardiographic indicators of the systemic intravascular volume status [IVCCI; the ratio of the early transmitral and early myocardial diastolic velocities (E/Em)] were evaluated at baseline, and the clinical status during follow-up was compared across the IVCCI levels...

BACKGROUND: In aortic stenosis (AS), the left ventricle (LV) should face an increased afterload that is due to both the stenotic aortic valve and the peripheral vascular resistance (PVR). Valvulo-arterial impedance (ZVa ) is a recently introduced parameter, which permits the evaluation of global LV afterload in AS. Aim of this study was to assess the influence of increasing ZVa on the longitudinal, circumferential, and radial components of LV mechanics. METHODS: A total of 126 patients (mean age: 80...

We document the fifth pattern of takotsubo cardiomyopathy, in which the mid-LV is hyperdynamic but the apex and base are akinetic or hypokinetic. This is a reverse mid-ventricular takotsubo. The patient is a 79-year-old woman admitted with chest pain and initially a normal EKG. Her troponin I rose to 5.4 μg/L (0.02-0.03 μg/L) and she developed QT prolongation and widespread T-wave inversion. Coronary angiography showed only very mild atheroma. Follow-up echocardiogram six weeks later showed normal left ventricular function...

Congenital coronary sinus (CS) stenosis is a rare malformation. We present five patients with congenital coronary sinus stenosis (CSS) and identified another nine cases reported in the literature between 1980 and 2016. Congenital CSS may be associated with an unroofed CS, a coronary artery-coronary sinus fistula, or other cardiac anomalies. Congenital CSS may be detected by echocardiography, multidetector row computed tomography, and intra-operative evaluation. Congenital CSS can occur at the ostium, lumen, and origin of the CS...

AIMS: We studied how Doppler-derived hemodynamic parameters in children change as the relative prosthetic mitral valve (PMV) size decreases with somatic growth and evaluated the diagnostic utility of the parameters for detecting PMV obstruction in children. METHODS AND RESULTS: We reviewed 26 echocardiographic examination results of 15 mechanical bileaflet PMVs in 12 children. The median age at echocardiographic examination was 6.6 (0.6-18.1) years. The PMV functioned normally in 24 examinations but was obstructed due to thrombosis in two cases...

Here, we report a rare case of isolated leukemic infiltrate of the myocardium (extramedullary involvement) presenting as restrictive cardiomyopathy in a patient in complete remission of acute myeloid leukemia. It was evaluated with multimodality imaging studies (echocardiography and cardiac MRI) and further confirmed by pathology. The present case highlights the importance of maintaining a high degree of clinical suspicion when evaluating patients with progressive ventricular hypertrophy of unknown cause, including recognition of the potential involvement by recurrent hematologic malignancy...

BACKGROUND: Noninvasive diagnosis of exercise-induced elevation of left ventricular filling pressure is difficult and remains unsatisfactory. The aim of this study was to assess the accuracy of the ratio of early diastolic transmitral (E) to mitral annular (e') velocity and to determine new parameters or parameter combinations with the ability to predict exercise-induced left atrial pressure (LAP) elevation. METHODS AND RESULTS: Eighty patients with paroxysmal atrial fibrillation (AF) referred for catheter AF ablation underwent simultaneous exercise echocardiography and direct invasive LAP measurements, as well as a resting and postexercise biomarker analysis...

OBJECTIVES: Assessment of the prognostic role of left ventricular stiffness (LVS) in patients with aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI). METHODS: We performed a complete two-dimensional transthoracic echocardiographic study before and after TAVI in patients with severe AS at high surgical risk. In order to assess LVS, we measured LV end-diastolic pressure (EDP) invasively during TAVI and LV end-diastolic volume (EDV) by means of echocardiography...

OBJECTIVES: To identify unique echocardiographic features that could be used to reliably predict LVEF recovery upon resolution of sinus tachycardia in patients with cancer. BACKGROUND: Sinus tachycardia may be a manifestation of underlying cardiomyopathy or can lead to a reversible form of dilated cardiomyopathy known as tachycardia-mediated cardiomyopathy. While distinguishing the two can be challenging, predicting recovery regardless of cause can be of significant clinical importance in the cancer population...

OBJECTIVES: The tricuspid annular plane systolic excursion (TAPSE) is a validated measure of right ventricular function; however, the apical echocardiographic window varies and has limitations in intensive care unit (ICU) patients receiving mechanical ventilation or those with underlying disease and air entrapment. We aimed to evaluate the subcostal echocardiographic assessment of tricuspid annular kick (SEATAK) as an alternative to TAPSE in critically ill patients. METHODS: To measure SEATAK, we obtained the subcostal inferior vena cava view and used M-mode to measure excursion of the tricuspid annulus (kick)...

BACKGROUND: Right atrium function and ventricular function have significant prognostic value in pulmonary arterial hypertension patients. Acute changes in right ventricular synchrony and right atrium function postiloprost inhalation have not been evaluated. METHODS: Cross-sectional study. Consecutive pulmonary arterial hypertension patients (group I from Nice classification) were included. Echocardiographic right atrium and right ventricular function pre- and postiloprost inhalation, including a right ventricular dyssynchrony index and right atrium function using speckle tracking, were performed in all patients...

Formation of an intramural left atrial hematoma (ILAH) is a rare complication of coronary artery stenting. Rapid diagnosis with noninvasive multimodality imaging can potentially be lifesaving. We report a case of ILAH that resulted in left ventricular inflow obstruction and pericardial tamponade in a 55-year-old male who presented with hemodynamic instability and worsening dyspnea three weeks after seemingly uncomplicated left circumflex artery stenting. We demonstrate features on transthoracic echocardiography with contrast and cardiac computed tomography that were used for diagnosis and management...

Aortic rupture and transection are constituents of the acute aortic syndrome. Injury to the thoracic aorta during motor vehicle crashes is associated with blunt chest trauma and rapid deceleration mechanisms. Type A dissections and/or rupture of the aorta at the level of the aortic isthmus are the more common presentations of aortic injuries associated with motor vehicle crashes. We present the case of atypical echocardiographic findings of a nearly complete circumferential transection of the proximal ascending aorta injury after a motorcycle crash...

INTRODUCTION: Quantification of mitral regurgitation (MR) by two-dimensional (2D) transthoracic echocardiography (TTE) is based on the analysis of the proximal flow convergence (PFC) and the "vena contracta" (VC). This method assumes geometries and can be misleading. In contrast, three-dimensional (3D) echocardiography directly measures flow volumes and does not assume geometries, which allows for more accurate MR evaluation. AIMS: To report the 3D transesophageal echocardiography (3DTEE) feasibility for MR quantification and evaluate its concordance with 2D echo...

Multi-imaging modalities should be considered in patients with atrial septal defects (ASDs) in which the degree of right ventricular enlargement is not fully explained by the small size of ASD found on conventional transthoracic echocardiography. We report a case of crescent-shaped superior sinus venosus ASD discriminated using real-time three-dimensional transesophageal echocardiography. MDCT confirmed its relationship with the superior vena cava and the absence of combined anomalies, such as the pulmonary venous return anomaly...

Congenital stenosis/atresia of a coronary artery is an exquisitely rare anomaly (Congenit Heart Dis, 2, 2007, 347) with increased risk of sudden death. Bilateral coronary obstruction is even more unusual but has been reported in conjunction with aortic valve disease, syphilis, and Takayasu's arteritis. To the best of our knowledge, obstruction of both coronaries in a pediatric patient has only been reported once (Ann Thorac Surg, 55, 1993, 1564). We present a patient with an intramural, anomalous aortic origin of the right coronary artery from the contralateral sinus (AAORCA) with near atresia of the left main coronary ostium...
