We aim to determine the function of Right ventricle post mitral valve surgeries in patients with pulmonary hypertension using transthoracic echocardiography3- and 6-months post-operatively to detect the effect of mitral valve surgeries over the RV function whether improving, deteriorating, or not changing at all.

Inclusion Criteria:

• Patients who underwent mitral valve surgeries who also had pulmonary hypertension in the period between March 2019 and March 2022 in Assiut university heart hospital

Exclusion Criteria:

• Patients who underwent mitral valve surgeries with normal pulmonary pressure. Patients who had other valve surgeries besides mitral as aortic and/or tricuspid valve surgeries. Patients had mitral valve surgeries with other heart conditions that needed another intervention in the same session as CABG for IHD.
