Cardiac tumors: imaging findings, clinical correlations and surgical treatment in a 15 years single-center experience

This record contains raw data related to the article “Cardiac tumors: imaging findings, clinical correlations and surgical treatment in a 15 years single-center experience”<br> Abstract <strong>Background: </strong>We aimed to: present the clinical and pathological characteristics of cardiac tumors in a single-center series of patients, describe the association of imaging characteristics, clinical presentation and surgical treatment, analyze if second level imaging tests, computed tomography (CT) and cardiac magnentic resonance (CMR), improve the diagnostic accuracy when compared to first-line imaging technique (transthoracic echocardiography,TTE). <strong>Methods: </strong>We reviewed the medical and surgical records, TTE, CT and CMR examinations of 86 patients with an histological diagnosis of cardiac tumors between 2004 and 2019. <strong>Results: </strong>The majority were benign tumors (81%) with myxoma accounting for 66% of cases. Among malignancies, metastasis (8%) and primary tumors (10%) were equally recognized. Symptoms at presentation (45% of patients) were associated to larger diameters at TTE. Malignancies were larger (mean diameter 37±14 mm vs 27±13 mm, p&lt;0.01), more frequently exhibited irregular shape (67% vs 17%, p&lt;0.01), frayed or polylobulated surface (73% vs 38%, p=0.035), heterogeneous aspect (67% vs 32%, p=0.012). A maximum diameter &gt;28mm and a minimum diameter &gt;19.5mm emerged as possible cut-off values for the differentiation of benign and malignant tumors. The ability of TTE, CT and CMR features in identifying malingnancies was moderate (diagnostic accuracy of 84%, 81%, 76% respectively). The mean survival time after surgery was 1.6±1.4 years in malignancies and 6.8±4.7 years in benign tumors. <strong>Conclusions: </strong>Cardiac tumors are rare and mostly benign; their nature and clinics related to TTE appearance. CT and CMR may be used sinergically with TTE. Surgery is curative in benign tumors, survival remains scarce in malignancies.本数据集收录与论文《心脏肿瘤：15年单中心经验的影像学表现、临床关联与外科治疗》相关的原始数据 **背景**：本研究旨在达成以下目标：1）呈现单中心队列中心脏肿瘤患者的临床与病理特征；2）阐述影像学特征、临床表现与外科治疗方案之间的关联；3）分析相较于一线影像学技术经胸超声心动图（transthoracic echocardiography, TTE），二级影像学检查即计算机断层扫描（computed tomography, CT）与心脏磁共振成像（cardiac magnetic resonance, CMR）是否可提升诊断准确率。 **方法**：本研究回顾了2004年至2019年间86例经组织病理学确诊为心脏肿瘤的患者的临床与外科病历、TTE、CT及CMR检查资料。 **结果**：本队列中绝大多数为良性肿瘤（81%），其中黏液瘤占比达66%。恶性肿瘤组中，转移瘤（8%）与原发性恶性肿瘤（10%）占比相当。45%的患者就诊时存在临床症状，且症状与TTE检测到的更大肿瘤直径存在相关性。恶性肿瘤的平均直径更大（恶性组37±14 mm，良性组27±13 mm，p<0.01），更常表现为不规则形态（67% vs 17%，p<0.01）、表面毛糙或分叶状（73% vs 38%，p=0.035）以及不均匀影像学表现（67% vs 32%，p=0.012）。研究确定了区分良恶性肿瘤的临界值：最大直径＞28mm、最小直径＞19.5mm。TTE、CT及CMR识别恶性肿瘤的诊断效能中等，诊断准确率分别为84%、81%与76%。恶性肿瘤患者术后平均生存期为1.6±1.4年，良性肿瘤患者则为6.8±4.7年。 **结论**：心脏肿瘤较为罕见，且多为良性；其生物学特性与临床表现与TTE影像学表现密切相关。CT与CMR可与TTE协同应用。良性肿瘤患者经手术治疗可获得根治效果，而恶性肿瘤患者术后生存期仍普遍较短。
