CARDIOLOGY

Recall the clinical and laboratory manifestations of an acute ventricular septal defect.

Explanation:

About 3-7 days post MI a patient who goes into sudden cardiogenic shock and has a new holosystolic murmur in an area other than the mitral area-best heard in the parasternal area. Confirm the diagnosis by using echo with doppler or by inserting a swan Ganz catheter to see a step up of oxygen saturation from RA to RV by more than 5%.
