Pulmonary wedge pressure recorded in basal condition shows a high V wave (A) secondary to severe mitral regurgitation. After clip implantation, the V wave is reduced (B). The parallel A-wave reduction indicates diminished end-diastolic pressure. These variations in aggregate result in diminished mean wedge pressure after clip implantation. In this case example, the systemic pressure varied from 100/60 mmHg before clip implantation to 130/70 mmHg after clip implantation, following fluid challenge and norepinephrine administration.
