The recommended method to measure left atrial diameter in the parasternal long axis view is the inner edge to inner edge technique, perpendicular to the aortic root, measured at end-diastole. This approach provides the most reproducible and standardized measurement.

Measurement parallel to the aortic root or at end-systole is less accurate. Outer edge measurements overestimate size.

ASE chamber quantification guidelines specify this method for standardization and reproducibility in adult echocardiography practice【12:ASE Chamber Quantification Guidelines†p.90-95】【16:Textbook of Clinical Echocardiography, 6e†p.120-125】.

Cardiac catheterization with coronary angiography is considered the gold standard for the assessment and diagnosis of coronary artery disease (CAD). It provides direct visualization of coronary artery luminal stenosis and allows for therapeutic intervention if needed.

While cardiac magnetic resonance imaging (MRI), stress echocardiography, and myocardial perfusion imaging are valuable non-invasive modalities for ischemia detection and functional assessment, none replace the anatomical and interventional capabilities of invasive angiography.

This is well established in the "Textbook of Clinical Echocardiography, 6e", Chapter on Ischemic Heart Disease and Diagnostic Modalities【20:400-405†Textbook of Clinical Echocardiography】.

The echocardiographic image shows a typical atrial septal defect located in the central portion of the atrial septum, best classified as a secundum atrial septal defect (ASD). Secundum ASDs are the most common type, occurring in the fossa ovalis region.

Sinus venosus ASDs are located near the superior vena cava or inferior vena cava junctions, coronary sinus ASDs involve unroofing of the coronary sinus, and primum ASDs occur low in the atrial septum near the atrioventricular valves.

These anatomic distinctions are critical for diagnosis and surgical planning and are detailed in adult congenital heart disease and echocardiography references【16:Textbook of Clinical Echocardiography, 6e†p.565-570】【12:ASE Adult Congenital Guidelines†p.400-410】.

The subcostal view is the preferred transthoracic echocardiographic window to assess atrial situs, especially in congenital heart disease. This view provides a cross-sectional look at the abdominal organs and atrial chambers, helping determine the relative position of the inferior vena cava and aorta, which aids in defining atrial situs (solitus, inversus, or ambiguous).

Short axis and long axis views provide excellent cardiac anatomy but are less informative for visceral situs. The suprasternal notch window is mainly used to visualize the great vessels but does not provide adequate assessment of atrial situs.

The subcostal view's ability to demonstrate abdominal situs and systemic venous return makes it essential in congenital cardiac evaluations and is recommended in echocardiography protocols for congenital heart disease assessment .

The 'flying W' sign refers to a characteristic spectral Doppler and M-mode pattern observed in the pulmonic valve inflow in patients with pulmonary hypertension. This pattern represents mid-diastolic notching or fluttering caused by increased pulmonary artery pressure and delayed right ventricular relaxation.

This sign is associated specifically with the pulmonic valve and pulmonary hypertension, not with prostheses or tricuspid valve pathology.

This finding is discussed in echocardiography and pulmonary hypertension guidelines and texts【16:Textbook of Clinical Echocardiography, 6e†p.280-285】【12:ASE Pulmonary Hypertension Guidelines†p.300-305】.

The left atrial volume index (LAVI) is the left atrial volume normalized to the patient's body surface area (BSA), which accounts for patient size. To calculate BSA, height and weight are required, most commonly using formulas such as the Mosteller formula.

Therefore, height is a necessary parameter to calculate the left atrial volume index. Age, blood pressure, and cardiac output are not used in the calculation of LAVI but may be clinically relevant for interpretation.

This approach standardizes LA size across patients of different body habitus, making LAVI a more accurate and reproducible measure of LA remodeling and a predictor of cardiovascular outcomes.

The echocardiography guidelines and textbooks emphasize the importance of indexing LA volume to BSA and highlight height as a required measurement for this purpose .

Peak tricuspid regurgitant velocity (TRV) allows estimation of right ventricular systolic pressure (RVSP) using the simplified Bernoulli equation: RVSP = 4 × (TRV)^2 + estimated right atrial pressure.

This measurement is important for assessing pulmonary hypertension indirectly.

Right atrial pressure is estimated separately, pulmonary artery diastolic pressure and mean pressure require additional measurements.

This application is discussed in the "Textbook of Clinical Echocardiography, 6e", Chapter on Right Heart Pressure Estimation【20:335-340†Textbook of Clinical Echocardiography】.

The video suggests an atrial septal abnormality possibly a patent foramen ovale or interatrial shunt. To evaluate for right-to-left shunting across an atrial septal defect, the administration of agitated saline contrast with a Valsalva maneuver is the next best step.

Valsalva increases right atrial pressure transiently, promoting transient right-to-left shunting, making microbubbles visible in the left atrium if a shunt is present. Administration without Valsalva reduces sensitivity. The choice of arm vein (right or left) is less critical.

This diagnostic technique is well described in ASE adult congenital heart disease guidelines and echocardiography contrast protocols【12:ASE Contrast Echocardiography Guidelines†p.190-195】【16:Textbook of Clinical Echocardiography, 6e†p.575-580】.

Cardiac contusion is a myocardial injury resulting from blunt chest trauma, typically affecting the right ventricle more commonly than the left ventricle because of its anterior location and proximity to the chest wall. The injury can range from mild bruising to severe myocardial damage and dysfunction.

It does not result from myocardial infarction (which is ischemic injury), nor does it cause hypertrophy or hypercontractility. Instead, it may cause wall motion abnormalities, arrhythmias, or even rupture.

These features are detailed in echocardiography and trauma cardiology literature, including the "Textbook of Clinical Echocardiography" and clinical guidelines on blunt cardiac injury【16:Textbook of Clinical Echocardiography, 6e†p.600-605】【12:ASE Trauma Cardiology Guidelines†p.500-505】.

Intravenous drug use is a major risk factor for infective endocarditis, particularly involving the tricuspid valve and sometimes left-sided valves. Symptoms like fever, flu-like illness, dyspnea, and chest pain suggest possible septic emboli or valve destruction.

Echocardiographic findings associated with endocarditis include mobile echogenic masses attached to valve leaflets (vegetations), valve thickening, or destruction. These findings are diagnostic and guide treatment.

Aortic dissection, hypertrophic cardiomyopathy, and mitral valve prolapse can present with different clinical features and echocardiographic findings not consistent with infectious vegetations.

These clinical and echocardiographic correlations are detailed in the ASE guidelines on infective endocarditis and the "Textbook of Clinical Echocardiography"【16:Textbook of Clinical Echocardiography, 6e†p.470-475】【12:ASE Infective Endocarditis Guidelines†p.380-390】.
