Key result
Transthoracic echocardiography is a non-invasive, repeatable diagnostic tool that, when combined with transesophageal echocardiography, provides precise information on cardiac function for perioperative management.
Why the study?
Transthoracic echocardiography (TTE) is the fundamental echocardiographic technique used perioperatively, but its development and application for anesthesiologists require clarification.
Transthoracic echocardiography is a fundamental, non-invasive tool that, when combined with transesophageal echocardiography, enhances perioperative cardiovascular management.
周術期管理において経食道心エコー法（transesophageal echocardiography：TEE）が頻用されるようになってきたが，心エコー法の基本は経胸壁心エコー法（transthoracic echocardiography：TTE）である．TTEは術前評価からベッドサイドでの診断まで，さまざまな状況で用いられる手技であるが，その最大の特徴は非侵襲的手技であり，ベッドサイドで繰り返し施行することができることである．TTEでは，傍胸骨アプローチ（長軸像，短軸像），心尖部アプローチ（四腔像，五腔像，二腔像，長軸像）などで心腔を描出し，断層心エコー法，ドプラー心エコー法で診断と評価を行う．周術期管理においては，TTEとTEEのコンビネーションで用いることによって，心エコー法の有用性がより高まると考えられる．

Akamatsu et al. (2011) conducted a review in Perioperative management of cardiac disorders. Transthoracic echocardiography (TTE) was evaluated. Transthoracic echocardiography is a non-invasive, repeatable diagnostic tool that, when combined with transesophageal echocardiography, provides precise information on cardiac function for perioperative management.
