OBJECTIVE: Tricuspid annular plane systolic excursion (TAPSE) represents movement of the lateral annulus of the tricuspid valve toward the apex and denotes right ventricular contractility in the long axis. In transesophageal echocardiography with the probe in the mid-esophagus, TAPSE occurs at a significant angle to the M-mode scan line. The authors describe a novel method to assess TAPSE in 2 dimensions (2D) and compare this with an established method. DESIGN: Prospective cohort study...

RATIONALE: Calcific aortic stenosis (AS) is characterized by calcium deposition in valve leaflets. However, women present lower aortic valve calcification (AVC) loads than men for the same AS hemodynamic severity. OBJECTIVE: We thus aimed to assess sex-differences in aortic valve fibro-calcific remodelling. METHODS AND RESULTS: One hundred and twenty-five patients underwent Doppler-echocardiography and multidetector-computed-tomography within 3 months prior to aortic valve replacement...

In fetuses with Ebstein anomaly or tricuspid valve dysplasia (EA/TVD), poor hemodynamic status is associated with worse neonatal outcome. It is not known whether EA/TVD fetuses with more favorable physiology earlier in gestation progress to more severe disease in the third trimester. We evaluated if echocardiographic indexes in EA/TVD fetuses presenting <24 weeks of gestation are reliable indicators of physiologic status later in pregnancy. This multicenter, retrospective study included 51 fetuses presenting at <24 weeks of gestation with EA/TVD and serial fetal echocardiograms ≥4 weeks apart...

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: Transcatheter cryoablation is a well-established technique for the treatment of atrioventricular nodal reentry tachycardia (AVNRT) in children. Nevertheless, atrioventricular nodal slow-pathway conduction may recur after an acutely successful procedure. The aim of this study was to evaluate the long-term outcome of acutely successful AVNRT cryoablations in pediatric patients in case of focal cryolesion and in case of need for High-Density Linear Lesion (HDLL) cryoablation due to focal failure...

BACKGROUND: Traditional two-dimensional (2D) echocardiographic evaluation of tricuspid annulus (TA) dilation is based on single-frame measurements of the septolateral (S-L) dimension. This may not represent either the axis or the extent of dynamism through the entire cardiac cycle. In this study, we used real-time 3D transesophageal echocardiography (TEE) to analyze geometric changes in multiple axes of the TA throughout the cardiac cycle in patients without right ventricular abnormalities...

Right ventricular (RV) dysfunction harbingers adverse prognosis in pulmonary arterial hypertension (PAH). Although conventional two-dimensional echocardiography (2DE) is limited for RV systolic function quantitation, RV strain can be a useful tool. The diagnostic and prognostic impact of 2DE speckle-tracking RV longitudinal strain was evaluated, including other 2DE systolic indexes, in a group of PAH patients without severe impairment of functional capacity, chronic pulmonary thromboembolism or left ventricular dysfunction...

Evidence suggests an association between left heart obstructive lesions and dilated coronary sinus (DCS), but this has not been studied in fetuses. A retrospective review of fetal echocardiograms (FE) over an 8-year period was conducted, and patients with DCS were identified and confirmed postnatally. There were 5840 FE performed on 4920 women during this period. Of 49 patients with DCS, 22 had normal intracardiac anatomy and 27 patients had congenital heart disease (CHD) yielding an incidence of 4.6 % in the presence of CHD (27/584)...
