- Quantification of lung perfusion by a novel echocardiographic approach in pediatric pulmonary vein stenosisby Joseph M. Stidham, Sarah LaBarge, Jennifer H. Huang, Lars Grosse-Wortmann, Patrick D. Evers on December 19, 2024 at 12:00 am
- Sex-specific differences in echocardiographic parameters of risk stratification in pulmonary arterial hypertensionby Nicola Benjamin, Veronika Schiffer, Carolin Resag, Panagiota Xanthouli, Moritz Braun, Satenik Harutyunova, Christina A. Eichstaedt, Benjamin Egenlauf, Alberto M. Marra, Eduardo Bossone, Antonio Cittadini, David G. Kiely, Ekkehard Grünig on December 18, 2024 at 12:00 am
This is the first study focusing on sex differences in right heart size obtained by echocardiography in PAH. For risk stratification indexation of RA-area to body surface area could be more considerate to body composition. In contrast, TAPSE/sPAP values were not sex-dependent and were a robust prognostic factor in PAH.
- IMPACT OF LENGTH INDEXING OF DEFORMATION IN ECHOCARDIOGRAPHIC EVALUATION OF RIGHT VENTRICULAR FUNCTIONby Weiting Huang, James Hodovan, Avneesh Sharma, Matteo Morello, Onur Varli, Bethany Gholson, Jonathan R. Lindner on December 17, 2024 at 12:00 am
When assessing right ventricular (RV) function by echocardiography, some discordance between the deformational indices is predicted based on the influence of RV length. RV free wall longitudinal strain (RVFWS) is relatively independent of RV length, whereas tricuspid annular plane systolic excursion (TAPSE) reflects the strain-length product. Systolic annular velocity (s') (distance over time) is […]
- The Right Ventricle and Exercise Capacity in Adults with Repaired Tetralogy of Fallot: Passive Bystander or Active Participant?by Zachary Barrett-O’Keefe, Chera L. Maarouf, Jessica A. Narum, Timothy J. Fuller, James M. Welper, William R. Miranda, C. Charles Jain, Heidi M. Connolly, Luke J. Burchill, Alexander C. Egbe on December 16, 2024 at 12:00 am
Exercise intolerance is a hallmark symptom in adults with repaired tetralogy of Fallot (TOF). This may be attributed to the disease-related impairment in RV systolic function, augmentation in right ventricular (RV) load, and their combined effect on altering left ventricular (LV) hemodynamics. To further elucidate these mechanisms, we examined oxygen uptake (VO2) by indirect-calorimetry and […]
- Supine bicycle stress echocardiography at low altitude for identification of susceptibility to acute mountain sicknessby Yi Wang, Qingfeng Zhang, Kai Wang, Sijia Wang, Yong Jing, Shiyin Chen, Lan Shang, Chunmei Li, Yan Deng, Yun Xu, Lixue Yin on December 15, 2024 at 12:00 am
Exposure to high altitude may unpredictably lead to acute mountain sickness (AMS). The purpose of this study was to identify the predictors of AMS at low altitude by exercise stress echocardiography (ESE).

- The Prognostic Value of Right Ventricular Dysfunction in Dilated Cardiomyopathy: Superiority of 3D Right Ventricular Ejection Fraction over Conventional Parameters and over Right Ventriculo-Arterial Couplingby Aura Vîjîiac, Sebastian Onciul, Alina Scărlătescu, Cristian Vîjîiac, Maria Dorobanţu, Radu Vătășescu on December 13, 2024 at 12:00 am
- Utility of an Echocardiographic Machine Learning Model to Predict Outcomes in ICCU Patientsby Samy Aghezzaf, Augustin Coisne, Kenza Hamzi, Solenn Toupin, Claire Bouleti, Charles Fauvel, Jean-Baptiste Brette, David Montaigne, Reza Rossanaly Vasram, Antonin Trimaille, Gilles Lemesle, Guillaume Schurtz, Edouard Gerbaud, Clément Delmas, Marc Bedossa, Jean-Claude Dib, Vincent Roule, Etienne Puymirat, Martine Gilard, Marouane Boukhris, Nicolas Mansencal, Nabil Bouali, Stephane Andrieu, Trecy Gonçalves, Jean-Guillaume Dillinger, Patrick Henry, Theo Pezel on December 13, 2024 at 12:00 am
The risk stratification at admission in ICCU (intensive cardiac care unit) is crucial and remains challenging.
- UTILITY OF THE RATIO BETWEEN THE SIZE OF THE RIGHT ATRIUM AND THE RIGHT VENTRICLE AT END-SYSTOLE TO DIAGNOSE ATRIAL SECONDARY TRICUSPID REGURGITATIONby Alexandra Clement, Denisa Muraru, Samantha Fisicaro, Marco Penso, Michele Tomaselli, Noela Radu, Caterina Delcea, Alexandra S. Buta, Valeria Rella, Radu Sascau, Luigi P. Badano on December 10, 2024 at 12:00 am
In the multiparametric framework for diagnosing atrial secondary tricuspid regurgitation (A-STR), an end-systolic (ES) right atrial (RA) to right ventricular (RV) volume or area ratio ≥1.5 supports the diagnosis of A-STR over the ventricular STR phenotype (V-STR). However, this threshold value has never been tested.
- Cardiac Elastography with External Vibration for Quantification of Diastolic Myocardial Stiffnessby Tom Meyer, Brunhilde Wellge, Gina Barzen, Stefan Klemmer Chandia, Fabian Knebel, Katrin Hahn, Thomas Elgeti, Thomas Fischer, Jürgen Braun, Heiko Tzschätzsch, Ingolf Sack on December 6, 2024 at 12:00 am
Heart failure is an increasing global health problem. Approximately 50% of patients with heart failure have preserved ejection fraction (HFpEF) and concomitant diastolic dysfunction (DD), in part caused by increased myocardial stiffness not detectable by standard echocardiography. While elastography can map tissue stiffness, cardiac applications are currently limited, especially in patients with […]
- Are new thresholds required for the assessment of right ventricular function in patients with and without tricuspid regurgitation?by X. Galloo, N. Ajmone Marsan on December 6, 2024 at 12:00 am
