Continuous murmur is seen in all the  following            

except-
A continuous murmur is predicated on
a pressure gradient that persists between
two cardiac chambers or blood vessels
across systole and diastole. The murmurs
typically begin in systole, envelop the
second heart sound (S 2 ), and continue
through some portion of diastole. They
can often be difficult to distinguish from
individual systolic and diastolic murmurs
in patients with mixed valvular heart disease.
The classic example of a continuous
murmur is that associated with a patent
ductus arteriosus, which usually is heard
in the second or third interspace at a slight
distance from the sternal border. Other
causes of a continuous murmur include
a ruptured sinus of Valsalva aneurysm
with creation of an aortic–right atrial
or right ventricular fistula, a coronary
or great vessel arteriovenous fistula, and
an arteriovenous fistula constructed to
provide dialysis access.
