May prompt TEE after normal TTE in prosthetic valve patients; hypothesis-generating from case reports and requires prospective validation.
What are the respective diagnostic values of transthoracic and transoesophageal Doppler echocardiography in patients with prosthetic heart valve thrombosis?
Transthoracic echocardiography is effective for diagnosing severely obstructive prosthetic valve thrombosis, but transoesophageal echocardiography is essential for detecting partial thrombosis with mild or absent obstruction.
