Heart tranplantation normal function
The following findings are typical after heart transplantation during follow up.
The following patient is 70 years old and currently 10 years after an orthotopic heart transplantation (which he received after a large anteroseptal myocardial infarction in the past leading to chronic heart failure). He has no cardiac complaints an ischemia was ruled out recently by a negative MIBI perfusion scan. The following ultrasound was performed during a routine outpatient control visit.
The LV dimensions and systolic function are normal. The measured LVEF is 55%. Notice the typical contraction pattern with a hyperkinetic inward motion of the posterolateral wall. The atria are enlarged due to the heart transplantation. There a no signs of valvular disease and the RVSP is normal
While the an E/A ratio of 2 in a 70 year old patient normally fits with an abnormal diastolic function, the diastolic function is normal in this case. The E/E` of 6 suggest normal filling pressures and the low A wave inflow velocity is a result of mechanical atrial “dysfunction” after surgery.
