Waveform diagnosis
Answer: Mitral Regurgitation
The large V wave in PA waveform signifies severe mitral regurgitation. Hemodynamic tracing in a patient with severe mitral regurgitation. The pulmonary arterial (PA) pressure is severely elevated ( more than 60 mm Hg). In the distal portion of the pulmonary arterial pressure wave, a second peak is seen; this represents the V wave coincident with the ventricular contraction. V waves are usually seen in the pulmonary capillary wedge-pressure waveform.
