Project description:ABSTRACT Unruptured sinus of Valsalva aneurysm can present with manifestations due to local compression or protrusion into the chambers. Right ventricular inflow obstruction is a rare manifestation. This image highlights the tricuspid valve obstruction due to a Valsalva aneurysm in a patient after surgical aortic valve replacement.

Native aortic valve thrombosis resembling papillary fibroelastoma.

Project description:The differential diagnosis of cardiac mass is important in determining the therapeutic plan and avoiding unnecessary surgical intervention. Non-invasive imaging methods would be useful in the diagnosis of suspected cardiac mass, because they may provide earlier diagnosis and more accurate assessment of cardiac mass. Native aortic valve thrombosis is a rare disorder and difficult to differentiate from a tumor, and in particular, a papillary fibroelastoma. Thus, the clinical decision making with imaging modalities should be performed cautiously. We recently met a female patient who had a aortic valve mass resembling papillary fibroelastoma in normal native valve. The patient underwent a surgical resection and the pathologic finding showed an organized thrombus with no evidence of papillary fibroelastoma.

Utility of real-time three-dimensional echocardiography in improved assessment of a mitral valve papillary fibroelastoma.

Project description:Primary cardiac tumors are exceedingly rare. They are usually first identified by transthoracic echocardiography. However, transesophageal echocardiography (TEE), with the aid of real-time three-dimensional (3D) imaging, can provide additional important mass characteristics. We present a case that demonstrates the usefulness of 3D TEE in characterizing a papillary fibroelastoma.

Multimodality imaging of a giant aortic valve papillary fibroelastoma.

Project description:Papillary fibroelastomas (PFEs) are benign cardiac tumors arising from endocardium. They are commonly found on valvular surfaces and average 1.0-1.5 cm in size. Though often asymptomatic, PFEs can lead to potentially severe complications, primarily due to their embolic potential. Surgical resection is recommended for all symptomatic or large PFEs. We report the case of a patient presenting with cardiovascular symptoms who was found to have a very large aortic valve PFE, as diagnosed by histopathologic examination following surgical resection. Multimodality cardiovascular imaging demonstrates the classic morphologic findings, including a pedunculated appearance and oscillating "frond-like" surface projections.

The elusive cause of syncope: Left atrial myxoma with mitral valve obstruction.

Project description:Key clinical messageSyncopal patients should be evaluated for cardiac causes, including myxoma, as highlighted in this case. Transthoracic echocardiography and coronary angiography are valuable diagnostic tools. Interventional cardiology plays a crucial role in the successful treatment of myxoma.AbstractThis case video describes the presentation and successful treatment of a 58-year-old woman who experienced recurrent episodes of syncope. After ruling out other health concerns, a pulmonary embolism was suspected and further investigations revealed a mass in the left atrium causing significant obstruction of the mitral valve. The mass, identified as a neovascularized myxoma, was successfully resected, emphasizing the significance of considering myxoma as a potential cause of syncope and highlighting the role of interventional cardiology in its management.

An atypical cause of myocardial infarction: case report of an obstructing papillary fibroelastoma of the aortic valve.

Project description:Papillary fibroelastomas are rare primary cardiac tumours with a prevalence of 0.01% at autopsy. They are histologically benign tumours but have been demonstrated through case series to confer an increased risk of thrombo-embolism resulting in: transient ischaemic attack, stroke, myocardial infarction, and pulmonary and systemic embolization. A 54-year-old woman presented with central chest pain radiating to her left arm. At presentation there was a significant troponin rise; initial high-sensitivity troponin-I (hsTn-I) 660 pg/mL increased to 3340 pg/mL at 6 h. Coronary angiogram did not reveal any obstructing coronary artery disease. Echocardiography revealed a rounded, mobile mass on the left coronary cusp of the aortic valve suspicious for papillary fibroelastoma. The patient underwent shave excision of the lesion. Intra-operatively it was noted that the mass intermittently sat within the ostium of the left main resulting in its occlusion. Histology confirmed a papillary fibroelastoma. Primary cardiac tumours are rare but can cause life-threatening complications such as stroke, myocardial infarction, and cardiac arrest. In the literature, the mechanism of these complications is mainly attributed to thrombo-embolism. This case demonstrates the utility of echocardiogram in investigating and diagnosing a rare cause of myocardial infarction and highlights an unusual mechanism, that is tumour causing obstruction of the coronary ostium.
