Voila—two separate chambers. If these don’t fuse though, then a gap is left between the two chambers, in other words, a ventricular septal defect, or VSD. The majority of cases are caused by a defect in the membranous portion of the septum.
A ventricular septal defect (VSD) is a defect in the ventricular septum, the wall dividing the left and right ventricles of the heart. The extent of the opening may vary from pin size to complete absence of the ventricular septum, creating one common ventricle.
PFO may refer to: Patent foramen ovale – a blood-flow pathway between a human heart's atriums, normally naturally closed after birth Personal Freedom Outreach – an Evangelical organization opposing cults
Atrial septal defect (ASD) is a congenital heart defect in which blood flows between the atria (upper chambers) of the heart.Some flow is a normal condition both pre-birth and immediately post-birth via the foramen ovale; however, when this does not naturally close after birth it is referred to as a patent (open) foramen ovale (PFO).
A variable-speed drive (VSD) air compressor is an air compressor that takes advantage of variable-speed drive technology. This type of compressor uses a special drive to control the speed ( RPM ) of the unit, which in turn saves energy compared to a fixed speed equivalent. [ 1 ]
Eisenmenger syndrome or Eisenmenger's syndrome is defined as the process in which a long-standing left-to-right cardiac shunt caused by a congenital heart defect (typically by a ventricular septal defect, atrial septal defect, or less commonly, patent ductus arteriosus) causes pulmonary hypertension [1] [2] and eventual reversal of the shunt into a cyanotic right-to-left shunt.
VSD – variable-speed drive; VSI – versatile seismic imager (Schlumberger VSP tool) [32] VSP – vertical seismic profile; VSPRO – vertical seismic profile; VTDLL – vertical thickness dual laterolog; VTFDC – vertical thickness FDC CNL log; VTISF – vertical thickness ISF log; VWL – velocity well log; VXT – vertical christmas tree
