yes during ventricular systole AV valves are closed.
I believe that is called diastole, in contrast to systole, the contraction of the heart muscles.
It is a defective ventricular contraction.
In late diastole (relaxation phase), the semilunar (pocket) valves close, due to decreasing arterial pressure, to prevent blood flowing back into the ventricles. These stay closed during atrial systole. (But open again during ventricular systole.)Then, as the ventricles contract during ventricular systole, the bicuspid and tricuspid valves close to prevent blood from flowing back to the atria.So, it really depends on which phase of the contraction we are looking at.(Ed: format)

The Aorta
ventricular systole
QRS complex
Right ventricular systole is pumping blood into the PULMONARY ARTERIES just as left ventricular systole is pumping blood into the AORTA -- both at the same time.Source: http://library.med.utah.edu/kw/pharm/hyper_heart1.htmlIn right ventricular systole, the blood enters the pulmonary trunk before proceding into the pulmonary arteries.
