To the Editor: Drs Stöllberger and Finsterer have posed a number of questions about our study on left ventricular noncompaction. This response has sections answering questions regarding the diagnosis and…
The authors discuss and present transesophageal echocardiographic images of intraoperative tako-tsubo cardiomyopathy in a female patient under general anesthesia. Intraoperative transesophageal echocardiography was performed in an attempt to manage a…
Background Left ventricular (LV) torsion and untwisting are important components of LV performance, but there is little information on the effect of age, particularly in younger populations. Methods LV rotation…
According to an old proverb, supposedly articulated in the 17 th century, but perhaps used first (although phrased differently) more than a hundred years earlier, “An old dog will learn…
Background Significant hemodynamic changes, including preload and afterload modifications, occur during the transition from the fetal to the neonatal environment. The ductus arteriosus closes, pulmonary vascular resistance decreases, and pulmonary…
Background The authors conducted an ultrasound interrogation of a mutant mouse model with a Dnah5 mutation to determine whether cardiac mechanics may be affected by reversal of cardiac situs. This…
Background Prominent azygos veins (PAVs) have been described with interrupted inferior venae cavae (IVCs) with heterotaxy. At the authors’ institution, cases of PAVs with uninterrupted IVCs have been noted. The…
Background The purpose of this multicenter study was to determine the reliability of visual assessments of segmental wall motion (WM) abnormalities and global left ventricular function among highly experienced echocardiographers…
Background The authors examined the feasibility of application of the American College of Cardiology Foundation’s appropriateness criteria for transesophageal echocardiography (TEE) and transthoracic echocardiography (TTE) at a large tertiary care…
Background The detection of atrial septal defects (ASDs) and other shunts is sometimes difficult on transthoracic echocardiography. In addition, the quantitative assessment of right-heart volume loading as an indicator of…
