<prompt> Diagnosis of structural diseases of the hea such as valvular hea disease is best shown byEsophageal DopplerThoracic bioimpedancePulmonary aery catheterisationTransesophageal echocardiography  <response>: Echocardiography types : Transthoracic echocardiography TTE Transesophageal echocardiography TEE TEE an ideal option to visualize the hea. TTE has the advantage of being completely noninvasive; however, acquiring the windows to view the hea can be difficult. Echocardiography uses are: Diagnosis of the source of hemodynamic instability, including myocardial ischemia, systolic and diastolic hea failure, valvular abnormalities, hypovolemia, and pericardial tamponade Guiding mitral valve repair. Estimation SV, CO, and intracavitary pressures Diagnosis of structural diseases of the hea, such as valvular hea disease, shunts, aoic diseases
