Background. The ­present ­study was ­designed to iden­ti­fy the per­i­op­er­a­tive fac­tors and to con­sid­er a coun­ter­plan for the improve­ment of sur­gi­cal ­results, ­based on the ­site of myo­car­dial infarc­tion.
Methods. Sixteen ­patients ­with post­in­farc­tion ven­tric­u­lar sep­tal per­fo­ra­tion under­went sur­gi­cal ­repair. The oper­a­tion was per­formed 5±3 ­days ­after the ­onset of ven­tric­u­lar sep­tal per­fo­ra­tion ­using the ­same meth­od, an infarc­tec­to­my and recon­struc­tion of the sep­tum and ­right and ­left ven­tric­u­lar ­walls ­with a sin­gle Dacron ­patch. The ven­tric­u­lar sep­tal per­fo­ra­tion was ante­ri­or in 11 ­patients and pos­te­ri­or in 5. Preoperative hemo­dy­nam­ics ­between sur­vi­vors and non-sur­vi­vors ­were com­pared. Left ven­tric­u­lar ­wall ­motion was esti­mat­ed ­using ech­o­car­di­og­ra­phy by ­wall ­motion ­score (divid­ed ­into 17 seg­ments and ­each seg­ment was grad­ed on a ­four-­point ­scale: nor­mal, 0; hypo­ki­net­ic, 1; ­severe hypo­ki­net­ic, 2; a- or dys­ki­net­ic, 3) and ­summed up.
Results. The oper­a­tive mor­tal­ity was 36% in 11 ­patients ­with ante­ri­or ven­tric­u­lar sep­tal per­fo­ra­tion. In non-sur­vi­vors com­pared to sur­vi­vors, ­wall ­motion ­score was great­er (25±4 vs 18±4, p<0.01) and all val­ues ­were ­over 20. The val­ue of the car­diac ­index divid­ed by Qp/Qs was low­er (0.98±0.09 vs 1.44±0.31, p<0.02) and all ­were ­under 1.1. In 5 ­patients ­with infe­ri­or ven­tric­u­lar sep­tal per­fo­ra­tion, the oper­a­tive mor­tal­ity was 40%. In non-sur­vi­vors com­pared to sur­vi­vors, ­wall ­motion ­score was great­er (18, 18 vs 7, 2, 12) and the ­right atri­al pres­sure was great­er (18, 19 vs 10, 9, 9 mmHg) due to a ­right ven­tric­u­lar infarc­tion.
Conclusions. The ­patients ­with ­poor ­left ven­tric­u­lar ­wall ­motion ­were ­lost for rea­sons unre­lat­ed to the ­site of myo­car­dial infarc­tion. Moreover, a car­diac ­index ­over Qp/Qs in ante­ri­or ven­tric­u­lar sep­tal per­fo­ra­tion and the exis­tence of a ­right ven­tric­u­lar infarc­tion in infe­ri­or ven­tric­u­lar sep­tal per­fo­ra­tion was pre­dic­tive of oper­a­tive mor­tal­ity.
