Lifetech Konar-multifunctional occluder is a novel device which is primarily used for the closure of ventricular septal defects. Being "multifunctional", the occluder has the potential to be useful in various structural cardiac defects.
We share our retrospective review from two centres regarding non-conventional usage of multifunctional occluders in CHD. Eight patients who underwent interventions using multifunctional occluders for lesions other than ventricular septal defects between March 2019 to September 2019 were included in the study. The patients were analysed based on demography, the size and type of lesion, procedural success, and development of complications. All patients were followed up in the outpatient department for a minimum period of 6 months.
The median age and weight of the cohort were 3.2 years and 9 kg, respectively. Six patients had patent ductus arteriosus, while one patient had aorto-pulmonary window and one had a coronary arterio-venous fistula. The sizing of the occluders and the procedural approach were based on the underlying pathology. The most commonly used occluder was 6 × 4 mm variant. One patient had successful implantation but had significant intra-device residual flow and was thus replaced by a different occluder. There were no major complications, nor any incidences of device embolisation or malposition. On follow-up, all patients had uneventful course.
Konar-multifunctional occluder can be safely used in lesions other than ventricular septal defects, when needed under specific circumstances. Its unique characteristics make it a versatile choice in a variety of cardiac lesions.
Lifetech Konar多功能封堵器是一种新型装置，主要用于闭合室间隔缺损。作为“多功能”封堵器，它有可能用于各种心脏结构缺陷。
我们分享了来自两个中心关于多功能封堵器在先天性心脏病（CHD）中的非常规应用的回顾性研究。纳入了2019年3月至2019年9月期间8例使用多功能封堵器治疗室间隔缺损以外病变的患者。根据人口统计学、病变大小和类型、手术成功率以及并发症的发生情况对患者进行分析。所有患者在门诊至少随访6个月。
该队列患者的中位年龄和体重分别为3.2岁和9千克。6例患者患有动脉导管未闭，1例患者患有主肺动脉窗，1例患者患有冠状动脉瘘。封堵器的尺寸选择和手术方法基于潜在的病理情况。最常用的封堵器型号是6×4毫米。1例患者植入成功，但装置内有明显残余分流，因此更换为另一种封堵器。未发生重大并发症，也没有装置栓塞或位置不当的情况。随访期间，所有患者病情平稳。
在特定情况下，Konar多功能封堵器可安全用于室间隔缺损以外的病变。其独特的特性使其成为各种心脏病变的通用选择。
