Congenital aortic stenosis: A novel technique for ventricular pacing during valvuloplasty

Abstract

This study demonstrated that back-up guidewires can be used effectively and safely for pacing during BAV procedures. This technique omits probable complications related to a second vascular access and may shorten the procedure time and decreases costs by eliminating the use of an additional sheath and a temporary pacemaker electrode.

Balloon valvuloplasty in the treatment of congenital aortic valve stenosis — A retrospective multicenter survey of more than 1000 patients

“…It is of note that pacing is performed more in the older age groups, and it can be speculated that the need for an additional venous access might be partially responsible for its more restrictive use in small children. However, with rising evidence that rapid pacing might improve the outcome [18] and with an adapted technique without the need for an additional venous access [19], pacing may play a more important role in the future.…”

Rapid ventricular pacing: a novel technique to decrease cardiac output for giant basilar aneurysm surgery

“…Rapid ventricular pacing is particularly attractive for its immediate onset and cessation of action. Rapid ventricular pacing has been used for placement of thoracic endografts [4] and cardiac valves [5][6][7], aortic valvuloplasty [8][9][10], and coarctation stenting [11]. Rapid ventricular pacing, when compared with pharmacological methods such as adenosine or sodium nitroprusside, offers the advantage of a rapid return to prepacing BP levels and shortened procedure time, and it produces reliable and profound hypotension [1].…”

“…Rapid ventricular pacing (RVP) has been used to facilitate placement of endografts in the thoracic aorta [4], transcatheter prosthetic valves [5][6][7], balloon aortic valvuloplasty [8][9][10], and coarctation stenting [11]. A case in which a giant aneurysm clipping was attempted by inducing a low cardiac output (CO) state using RVP is presented.…”

Management of Congenital Aortic Stenosis by Catheter Techniques

“…The concept of pacing to achieve tachycardia is to temporarily reduce the cardiac output in order to stabilize the balloon position during inflation (Leon et al, 2010;Marshall et al, 2005;Gupta et al, 2010). Another method of reducing cardiac output, very popular a decade ago, was to inject intravenous adenosine rapidly to produce cardiac standstill (by inducing sinoatrial and atrioventricular block) to allow unproblematic balloon inflation (Karago et al, 2008). Many clinicians would not pace neonates particularly if the left ventricular function is decreased.…”
