INTRODUCTION
Severe heart failure decompensation requires circulatory mechanical support in emergency situations. Polish paracorporeal pulsatile pumps, POLVAD-MEV, are designed for biventricular end-stage heart dysfunction.
AIM
To evaluate long-term POLVAD-MEV therapy by multiple pump exchange in patients on a transplant list.
MATERIAL AND METHODS
There were 3 patients in INTERMACS level 1 referred for emergency POLVAD-MED implantation due to acute heart failure deterioration. The paracorporeal pulsatile mechanical support was applied due to severe biventricular dysfunction.
RESULTS
They were supported by paracorporeal biventricular POLVAD-MEV pumps for 438, 473 and 394 days until heart transplantation. During the hospitalisation the pumps required multiple pumps exchanges within 29 ±10 (4-49) day intervals.
CONCLUSIONS
POLVAD-MEV paracorporeal pulsatile pumps present a safe option for long-term circulatory support in a selected group of patients. Therapy requires pump exchange but enables survival while awaiting a heart transplant.
引言
严重心力衰竭失代偿在紧急情况下需要循环机械支持。波兰体外搏动泵POLVAD-MEV专为双心室终末期心脏功能障碍设计。
目的
通过在等待移植名单上的患者中进行多次泵更换来评估POLVAD-MEV的长期治疗效果。
材料与方法
有3例INTERMACS 1级患者因急性心力衰竭恶化而转诊接受紧急POLVAD-MED植入。由于严重的双心室功能障碍，采用了体外搏动机械支持。
结果
他们在接受心脏移植前，由体外双心室POLVAD-MEV泵支持了438天、473天和394天。住院期间，泵需要在29±10（4-49）天的间隔内进行多次泵更换。
结论
POLVAD-MEV体外搏动泵为特定患者群体的长期循环支持提供了一种安全选择。治疗需要进行泵更换，但能使患者在等待心脏移植期间存活。
