I commend the work of Groh et al . looking at the differences in estimating right ventricular pressures (i.e., tricuspid valve gradients) using Doppler echocardiography compared with catheter-measured pressures. Doppler-derived tricuspid…
We would like to thank Dr Tozzi for his thoughtful letter regarding our report titled “Elevated Left Ventricular Outflow Tract Velocities on Exercise Stress Echocardiography May Be a Normal Physiologic…
I would like to congratulate Wittlieb-Weber et al . on their publication highlighting the variability of left ventricular outflow (LVOT) velocities during exercise in apparently healthy children. Their study also demonstrated…
We appreciate the comments of Cantinotti et al . Since the introduction of Z scores in cardiology, limitations in the use of current pediatric nomograms for the mitral valve and aortic…
We read with interest the article by den Dekker et al . titled “Comparability of Z -Score Equations of Cardiac Structures in Hypoplastic Left Heart Complex,” which was recently published in…
Background Handheld ultrasound is emerging as an important tool for point-of-care cardiac assessment. Although cardiac ultrasound skills are traditionally introduced during postgraduate training, the optimal time and methodology to initiate…
Background The Amplatzer Cardiac Plug (ACP) device, used for percutaneous left atrial appendage closure, frequently presents as an unexplained figure-of-eight on echocardiography. The aim of this study was to clarify…
Background The aim of this study was to assess changes in right ventricular (RV) parameters determined by three-dimensional (3D) echocardiography and speckle-tracking echocardiography in patients with acute pulmonary embolism and…
Background The long-term prognosis of hypoplastic left heart syndrome is limited by progressive right ventricular dysfunction. The aim of this study was to determine the trends in single right ventricular…
Although the “stethoscope” was developed almost 200 years ago by René-Théophile-Hyacinthe Laennec and is unquestionably the foundation for classical teaching of the diagnostic physical examination, it is also true that…
