This study sought to gain insights into the magnitude of error resulting in echocardiographic interpretations in Indian subjects by using western data as the reference. Standard transthoracic echocardiographic examination was performed in 100 healthy volunteers (mean age 34.0±8.8 years, 59% males). Compared with the reference values published by the American Society of Echocardiography (ASE), our subjects had much smaller left ventricular (LV) end-diastolic dimension, end-systolic dimension, and end-diastolic volume (only 58%, 61%, and 61% of the subjects were having values within the ASE-defined normal ranges). Indexing to body surface area increased these proportions to 81%, 90%, and 68%, respectively. In contrast, LV ejection fraction and most of the measures of LV diastolic function coincided with the ASE-recommended age- and gender-specific values.

Background: Aortic stenosis (AS) is a complex condition with various hemodynamic subtypes, each with distinct clinical profiles and outcomes. This study aimed to assess the characteristics and outcomes of different AS phenotypes based on flow and gradient patterns.
Methods: In this retrospective cohort study, we included 930 patients who underwent transcatheter aortic valve replacement (TAVR) for severe symptomatic AS at Mayo Clinic sites from 2012-2017.

: The assessment of left ventricular (LV) filling pressure in heart failure (HF) poses a diagnostic challenge, as HF patients may have normal LV filling pressures at rest but often display elevated LV filling pressures during exercise. Rapid preload increase during passive leg lift (PLL) may unmask HF in such challenging scenarios. We explored the dynamic interplay between simultaneous left atrial (LA) function and volume using LA strain/volume loops during rest and PLL and compared its diagnostic performance with conventional echocardiographic surrogates to detect elevated LV filling pressure.

Hypertrophic cardiomyopathy (HCM) is a heterogeneous group of heart muscle disorders that affects millions, with an incidence from 1 in 500 to 1 in 200. Factors such as genetics, age, gender, comorbidities, and environmental factors may contribute to the course of this disease. Diagnosis of HCM has improved significantly in the past few decades from simple echocardiographic evaluations to a more complex, multimodal approach embracing advanced imaging, genetic, and biomarker studies.

Background: Cardiac amyloidosis (CA) is a challenging diagnosis, particularly when the classic signs, such as increased wall thickness in a non-dilated left ventricle (LV), are absent. This makes the diagnosis more difficult in patients with normal LV wall thickness. We present a case of CA without increased wall thickness and without the characteristic granular sparkling echotexture in a non-dilated LV.

Background: In patients with preserved left ventricular ejection fraction (LVEF), small ventricular size has been associated with reduced functional capacity, but its impact on clinical outcomes is unclear.
Objectives: The goal of this study was to determine the relationship between small heart size and premature mortality within a large multicenter adult patient cohort with transthoracic echocardiographic examinations.
Methods: We divided 366,484 individuals with LVEF ≥50% (including a subset of 279,442 individuals with high-normal LVEF ≥60%) by sex and increasing quartiles for LV end-diastolic volume (LVEDV), LVEDV indexed to body surface area (LVEDVi), and LV end-diastolic diameter to assess associations with 5-year mortality through linkage with the National Death Index.
