Background. In clin­i­cal prac­tice pul­mo­nary ­artery bal­loon coun­ter­pul­sa­tion (­PABC) has ­been uti­lized ­only in the oper­a­tive set­ting ­with the bal­loon ­housed in a ­graft ­attached to the pul­mo­nary ­artery. Clearly, per­cut­ane­ous inser­tion of a ded­i­cat­ed pul­mo­nary ­artery bal­loon is a desir­able ­goal for ­patients requir­ing tem­po­rary ­assist for ­right ven­tric­u­lar fail­ure.
Methods. To ­address the ques­tion of ­right sid­ed car­di­o­pul­mo­nary tol­er­ance for a chron­ic ind­well­ing pul­mo­nary ­artery bal­loon, six ­adult ­ewes under­went per­cut­ane­ous place­ment of an 11 ml pul­mo­nary ­artery bal­loon, via the femo­ral ­vein. Effective pump­ing and tim­ing ­were mon­i­tored for 48 ­hours at ­which ­time the ani­mals ­were sac­ri­ficed. At autop­sy ­gross and micro­scop­ic ­study of all ­right ­heart struc­tures, the pul­mo­nary arter­ies and the ­lungs ­were stud­ied for ­adverse ­effects.
Results. There ­were incon­se­quen­tial ­minor abra­sions to ­right ­heart struc­tures in ­most ani­mals. The pul­mo­nary ­artery in ­five of six ani­mals ­revealed ecchy­mos­es and ­some trans­mu­ral hem­or­rhage, but no necro­sis or per­fo­ra­tion. There was no pul­mo­nary inju­ry ­that ­could not be ­ascribed to post­op­er­a­tive ate­lec­ta­sis.
Conclusions. This ­study dem­on­strates ­that chron­ic pul­mo­nary ­artery bal­loon coun­ter­pul­sa­tion can be car­ried out for a peri­od of 48 ­hours with­out sig­nif­i­cant inju­ry to ­right ­heart and pul­mo­nary struc­tures in the ­ovine mod­el.
