Atrioventricular canal defect (AV canal defect) is a congenital cardiac malformation characterized by defects in the atrial and ventricular septa, along with abnormalities of the atrioventricular valves including cleft mitral valve. These features collectively cause shunting and valve regurgitation.
Ebstein anomaly primarily involves the tricuspid valve and right atrium, Marfan syndrome is a connective tissue disorder with different manifestations, and Shone syndrome involves left-sided obstructive lesions.
This is clearly outlined in the "Textbook of Clinical Echocardiography, 6e", Chapter on Congenital Heart Defects - Atrioventricular Septal Defects#20:120-125Textbook of Clinical Echocardiography#.

Tricuspid annular plane systolic excursion (TAPSE) is measured as the linear displacement of the tricuspid annulus during systole and is expressed in centimeters (cm). It quantifies right ventricular longitudinal systolic function.
Centimeters per second is a velocity measurement used in tissue Doppler imaging. Milliliters per minute refers to volume flow, and millimeters of mercury measures pressure.
This is standardized in the "Textbook of Clinical Echocardiography, 6e", Chapter on Right Ventricular Functional Assessment#20:320-325Textbook of Clinical Echocardiography#.

Mitral valve area (MVA) can be estimated using the pressure half-time (PHT) method, which relates the time it takes for the mitral valve pressure gradient to reduce by half during diastole. The formula used is:
MVA (cm²) = 220 / PHT (ms)
A PHT of 220 ms yields:
MVA = 220 / 220 = 1.0 cm²
However, this is a classic teaching; in actual practice, the formula is widely accepted and validated.
Given this, the options need to be reviewed carefully. Since the PHT is 220 ms, the MVA is approximately
1.0 cm², consistent with moderate mitral stenosis.
Therefore, the correct answer is B (1.0 cm²).
(Please note: Since your options may contain a typographical error-4,4 cm² instead of 4.4 cm²-and considering typical values, option B fits best.) This method and interpretation are described in the "Textbook of Clinical Echocardiography, 6e", Chapter on Mitral Stenosis and Doppler Hemodynamics#20:385-390Textbook of Clinical Echocardiography#.

Takotsubo cardiomyopathy, also known as stress-induced cardiomyopathy or "broken heart syndrome," predominantly affects postmenopausal women (usually older than 50 years) and often presents with acute chest pain and ST-segment elevation on the ECG mimicking acute myocardial infarction. However, coronary angiography reveals normal or non-obstructive coronary arteries.
Echocardiographically, Takotsubo cardiomyopathy is characterized by transient left ventricular systolic dysfunction with a typical pattern of apical ballooning and basal hyperkinesis. The wall motion abnormality extends beyond a single coronary artery territory, differentiating it from ischemic cardiomyopathy.
The diagnosis is supported by the clinical presentation, typical echocardiographic findings, and exclusion of obstructive coronary artery disease. The condition is usually reversible over days to weeks.
This is extensively described in the "Textbook of Clinical Echocardiography, 6e" (Chapter 8: Coronary Artery Disease and Takotsubo Syndrome), which highlights the typical patient demographics, presentation, echocardiographic features, and prognosis .

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 Guidelinesp.90-95##16:Textbook of Clinical Echocardiography, 6ep.120-125#.
