We aim to describe the diagnostic potential of transthoracic and transesophageal echocardiography in this field, and to discuss their reliability as modalities of choice for preoperative diagnosis. Methods and Results: We used several complementary diagnostic approaches: Color-Doppler transthoracic echocardiography, transesophageal echocardiography, regional myocardial perfusion test and three-dimensional transthoracic echocardiography. The latter was employed to confirm the previously performed tests. All tests revealed the presence of an echogenic, oval-shaped and well-delimited mass in the basal part of intervenetricular septum. Conclusion: Even though it was initially asymptomatic and characterized by scarce clinical manifestations, the intra-cardiac mass was reliably identified in this patient by means of the cited diagnostic modalities, which also allowed adequate surgical planning. The immunohistochemical examination revealed the secondary nature of this tumour. Basic and advanced echocardiography examinations were crucial in the decision-making process.展开更多

The prevalence of coronary disease or neovascular in patients with atrial myxomas is high, yet angiography is not routinely performed. Echocardiography is preferred for evaluation of myxoma, where coronary angiography clarifies the vascular supply of the tumour and may alter the surgical planning. We here report an interesting and rare case of a left atrial myxoma hyper vascularised by two anomalous arteries, from right coronary artery and circumflex artery demonstrated by preoperative coronary angiography. The mass was successfully excised and the diagnosis of cardiac myxoma was confirmed via histopathology. A review of the value of coronary angiography in detecting myxoma neovascularization is provided. Offering additional valuable information, coronary angiography can alter the surgical approach and may therefore be considered prior to myxoma resection.展开更多
