A four year old child was admitted for investigation of a cardiac murmur and cardiomegaly. Echocardiography showed a large left ventricular tumour, the extension of which was accurately defined by nuclear magnetic resonance imaging and the etiology confirmed by coronary angiography. Holter recordings showed salvoes of ventricular tachycardia. This is an interesting case because, despite echocardiography and nuclear magnetic resonance imaging, the precise nature of the tumour was revealed only by coronary angiography. This investigation also showed a significant decrease of the left ventricular ejection fraction. It is the only described haemangioma complicated by this type of ventricular hyperexcitability. Therefore, coronary angiography would seem to be necessary in the investigation of isolated myocardial masses which remain unidentified by non-invasive methods.
一名4岁儿童因心脏杂音和心脏扩大入院检查。超声心动图显示左心室有一个大肿瘤，其范围通过核磁共振成像精确界定，病因通过冠状动脉造影得以证实。动态心电图记录显示有室性心动过速发作。这是一个有趣的病例，因为尽管有超声心动图和核磁共振成像，但肿瘤的确切性质仅通过冠状动脉造影才得以揭示。这项检查还显示左心室射血分数显著降低。这是唯一报道的伴有此类心室过度兴奋的血管瘤。因此，对于通过非侵入性方法仍无法明确的孤立性心肌肿块，冠状动脉造影似乎是必要的检查手段。
