Probably no worries: If you have a significant cardiac history, then there may be a cause for concern, but these are both considered relatively normal ejection fractions and may be slightly different due to the differences in the way the echocardiogram was performed. Sometimes very frequent pvcs can affect ef, but they typically have to be quite pronounced (>25% of the underlying rhythm).
Dr. Liviu Klein

Would investigate it: Although both values for ejection fraction are within normal range, there is a drop that needs to be explained. In view of your PVC history, i would recommend a 24 hrs holter monitor, since frequent pvcs (usually more than 10%, especially in a bigeminal or trigeminal pattern) can cause the ejection fraction to drop.

No, that's normal: Not to worry. Ef of 55% is still a normal ef. The ef is variable within certain level depending on many factors.
Dr. Vasudev Ananthram

Just be sure....: Although ef of 55% is fine we want to make sure that it is not trending down. If you have numerous pvcs such as more than 25000 a day or continued uncommonly high heart rates, it can cause weakness of your heart muscle and may have to be addressed. Please discuss this issue with your doctor. If your pvcs are numerous, you may need a follow up echo in a year to see if ef is stable.

Difficult sometimes: Due to the particular location, sinus venous atrial septal defect is frequently difficult to see on transthoracic echocardiography, and may require transesophageal echocardiography to see and characterize.

To clarify: sinus venosus ASD may be more likely to be initially not visualized (missed) than other more common types of ASD due to lack of doppler appearance ("signals") from its particular location. The effect on the heart chamber sizes or physical findings would make one suspicious for an ASD.
