Imaging the right heart pulmonary circulation unit: Insights from advanced ultrasound techniques 下载免费PDF全文
Francesco Ferrara MD PhD Luna Gargani MD PhD Ellen Ostenfeld MD Michele D'Alto MD PhD Jaroslaw Kasprzak MD Damien Voilliot MD Christine Selton‐Suty MD Olga Vriz MD Alberto M. Marra MD Paola Argiento MD Anna A. Stanziola MD PhD Antonio Cittadini MD PhD Antonello D'Andrea MD PhD Eduardo Bossone MD PhD 《Echocardiography (Mount Kisco, N.Y.)》2017,34(8):1216-1231
The right heart pulmonary circulation unit (RH‐PCU) is a key determinant of prognosis in several cardiorespiratory diseases. Although right heart catheterization is considered the gold standard for pulmonary hemodynamic assessment, a comprehensive cardiovascular ultrasound approach is an essential step in the diagnostic–prognostic clinical pathway of patients with suspect or overt pulmonary hypertension. The exponential development of advanced ultrasound techniques (strain, 3‐dimensional echocardiography and lung ultrasound) has led to new insights into the evaluation of RH‐PCU structure and function, overcoming some limitations of standard Doppler echocardiography. In the near future, exercise Doppler echocardiography may become a useful technique for detecting a latent stage of pulmonary hypertension and for evaluating right ventricular contractile reserve. 相似文献

Endomyocardial fibrosis is a form of restrictive cardiomyopathy mainly affecting poor children and young adults in geographically restricted areas of Latin America, Africa, and Southeast Asia. The pathophysiological hallmark of the disease is focal or diffuse endocardial thickening involving mainly the inflow, the apices, and the subvalvular region leading to valvular regurgitation, diastolic dysfunction and obliteration of the ventricular apex. Advanced right‐sided disease has slow flow of blood through chambers with propensity of thrombus formation especially in the right atria. Although two‐dimensional transthoracic echocardiography remains the cornerstone for the diagnosis of this disease, the case presented here shows how three‐dimensional transthoracic echocardiography can add substantial information regarding the region of involvement of the right ventricle as well as the various characteristics of the right atrial thrombus. 相似文献

Mycotic aneurysm of the root of left subclavian artery associated with aortic coarctation discovered by echocardiography 下载免费PDF全文

A 16‐year‐old girl was admitted with a 7‐month history of recurrent fever, weight loss of 5 kg, and general poor health status. Blood culture was positive with Streptococcus viridans. Transthoracic echocardiography established an aneurysm of the root of left subclavian artery, associated with an aortic coarctation just before the origin of the left subclavian artery with a velocity of 4.8 cm/s. Three‐dimensional echocardiography demonstrated the entire inner structure of the aneurysm. Computed tomography reconstruction confirmed the presence of aortic coarctation and mycotic aneurysm, it also revealed an aberrant right subclavian artery. 相似文献

Three‐dimensional transesophageal echocardiography incremental value in a rare case of a bileaflet tricuspid valve 下载免费PDF全文

Detailed assessment of the tricuspid valve using two‐dimensional echocardiography is always challenging, as only two of three leaflets can be seen at a time. Three‐dimensional echocardiography can provide the enface view of the tricuspid valve that allows simultaneous visualization of all of the three leaflets. In a 42‐year‐old male patient scheduled for pulmonary endarterectomy, 3DTEE showed that the tricuspid valve is bileaflet, with one septal and another lateral leaflet. There were two commissures, one of them is anteriorly positioned and the other one is posterior. Our findings were confirmed intra‐operatively by direct surgical visualization of the tricuspid valve. 相似文献
