Echocardiography can be predicted whether a patient develops a significant mitral valvular insufficiency after balloon angioplasty. Wilkins was the first to develop a score that the risk of an unsuccessful balloon angioplasty can be estimated.<cite>2</cite> | Echocardiography can be predicted whether a patient develops a significant mitral valvular insufficiency after balloon angioplasty.
