Purpose Of Review: Right ventricular (RV) assessment has long been challenging and technically difficult using echocardiography. This is mainly the result of the asymmetrical shape of the RV making it difficult to visualize on one-or-two dedicated views, thus requiring multiple integrated views and subjective assessment. Measurement of tricuspid annular systolic plane excursion and RV tissue Doppler velocity have become relied-upon methods of objective assessments; however, have limitations for characterizing true RV physiology.
Recent Findings: Studies suggest that two-dimensional RV free wall longitudinal systolic strain (RVFWS) using speckle-tracking echocardiography has emerged as a reproducible, feasible and highly prognostic technique for quantifying RV function. This has been demonstrated for patients with heart failure, ischemic heart disease, pulmonary hypertension, infiltrative disease and many other types of cardiovascular disease.
Summary: The current review outlines the clinical use of RVFWS, and its integration with other commonly used echocardiographic measurements to more accurately assess RV function, cause and prognosis to guide and improve patient care decision making.

Background: Low-volume hypertonic solutions, such as half-molar lactate (LAC), may be a potential treatment used for fluid resuscitation. This study aimed to evaluate the underlying cardiovascular effects and mechanisms of LAC infusion compared to sodium-matched hypertonic sodium chloride (SAL).
Methods: Eight healthy male participants were randomized in a controlled, single-blinded, crossover study.

The purpose of this study was to explore the impact of papillary muscle (PPM) infarction on left atrial and ventricular strain parameters in patients with non-anterior ST-segment elevation myocardial infarction (NA-STEMI) using cardiovascular magnetic resonance (CMR). This retrospective study performed CMR scans on 88 consecutive patients with NA-STEMI (68 males, 65 ± 10.05 years).

Objectives: Supra-normal left ventricular ejection fraction (snLVEF) represents a heterogeneous group with distinct prognoses. Left atrial (LA) strain, measured by speckle tracking echocardiography (STE), is a validated prognostic indicator. This study aimed to evaluate LA and left ventricular (LV) mechanical strains in hypertensive patients with snLVEF.

Aim: Left atrial (LA) strain is emerging as a valuable metric for evaluating cardiac function, particularly under pathological conditions such as pressure overload. This preclinical study investigates the predictive utility of LA strain on cardiac function in a murine model subjected to pressure overload, mimicking pathologies such as hypertension and aortic stenosis.
Methods: High-resolution ultrasound was performed in a cohort of mice (n = 16) to evaluate left atrial and left ventricular function at baseline and 2 and 4 weeks after transverse aortic constriction (TAC).

Aim: To establish an imaging-based method to quantify left ventricular (LV) diastolic pressures.
Methods/results: In 115 patients suspected of coronary artery disease, LV pressure was measured by micromanometers and images by echocardiography. LV filling pressure was measured as LV pre-atrial contraction pressure (pre-A PLV).
