Patients receiving heterotopic ("piggyback") cardiac transplants, when the patient's own and transplanted donor hearts are connected in parallel, present special problems in determining their relative contributions to total cardiac function. Three patients who had transplants because of intractable heart failure were studied using first pass and gated equilibrium technetium-99m-labeled blood pool scintigraphy. In one patient, thallium-201 myocardial perfusion scans were obtained. These nuclear cardiology techniques provided anatomic and functional information noninvasively that proved helpful in patient management.
接受异位（“背驮式”）心脏移植的患者，其自身心脏与移植的供体心脏并联连接，在确定它们对心脏总功能的相对贡献方面存在特殊问题。对三名因顽固性心力衰竭接受移植的患者使用首次通过法和门控平衡锝-99m标记血池闪烁扫描进行了研究。在一名患者中，还进行了铊-201心肌灌注扫描。这些核心脏病学技术以无创方式提供了解剖和功能信息，事实证明对患者管理有帮助。
