Abstract:
We report a 49-year-old morbidly obese female with a poor acoustic window in whom live/real time three-dimensional transthoracic echocardiography was able to make a confident diagnosis of cor triatriatum sinister. En face views of the membrane facilitated accurate assessment of the size and shape of the large nonobstructing opening in the membrane. Maximum dimensions of the opening were 3.06 x 1.03 cm and area was 2.3 cm(2).

Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...

Normal Heart Sounds
S1 (First Heart Sound)-
S1 is made by the closure of the mitral and tricuspid valves (atrioventricular valves), marking the beginning of systole.
S2 (Second Heart Sound)-
S2 is made by the closure of the aortic and pulmonic valves (semilunar valves), marking the end of the systole.
