Holodiastolic reversal flow in the common carotid: another indicator of the severity of aortic regurgitation.

Aortic regurgitation (AR) causes an increased diastolic reverse flow at various levels of aorta and its branching vessels. A prospective study was designed to evaluate the feasibility and accuracy of duplex sonography of the common carotid artery (CCA) in patients with various degrees of AR quantified by cardiac angiography. Twenty-four patients, with pure angiographic AR, of mean age 63.5 + 2.5-year old were included. Holodiastolic reverse flow (HRF) was recorded in all seven patients with severe angiographic AR (five with grade III and two with grade IV) and in none of the seventeen patients (eight with grade I and nine with grade II) with mild angiographic AR (p < 0.001). Furthermore, HRF was recorded both in the CCA and in the aorta, where it represents another criterion of severe AR, of six patients with severe angiographic AR and was absent in the eleven patients with grade I or II AR (p < 0.001). Demonstration of HRF in the CCA may be a very helpful criterion in distinguishing patients with severe AR.

Eustachian valve mimicking a right atrial cystic tumor.

We report the case of a 65-year-old patient referred to our hospital for stroke. In the course of the diagnostic procedure, a transesophageal echocardiography was performed and showed at first sight a mass attached to the right aspect of the interatrial septum and mimicking a cystic tumor. But after performing multiple views, it was in fact demonstrated a large Eustachian valve with its extremity attached to the right aspect of the interatrial septum. The increasing use of transesophageal echocardiography to evaluate patients makes it important for echocardiographers to recognize this anatomic entity and its normal variants.

Right- and left-sided interatrial septal aneurysm mimicking atrial tumor and stroke.

We report the cases of two patients with cerebral embolization and interatrial septal aneurysm. Transesophageal echocardiography required for stroke showed right-sided interatrial septal aneurysm in the first patient and left-sided interatrial septal aneurysm in the second. In the two patients, interatrial septal aneurysm was mimicking atrial cystic tumor or abscess. Significant internal carotid artery stenosis was found in the first patient and aortic arch atheroma with mobile components but no patent foramen ovale in the second patient. In the two patients, interatrial septal aneurysm appears to be only an incidental finding and not the true cause of stroke. Furthermore, we discuss the differential diagnoses of atrial masses.

Giant interatrial septal aneurysm mimicking a right atrial tumor.

We report the case of a patient with a giant interatrial septum aneurysm who was admitted to our hospital for analysis of palpitations. Transthoracic echocardiography was not contributive and cardiac magnetic resonance imaging demonstrated a small interatrial septal aneurysm. In our study, only transesophageal echocardiography provided the correct diagnosis, showing a giant interatrial septal aneurysm protruding far away into the right atrium and mimicking a right atrial cystic tumor.

[Cerebrovascular complication caused by aortic atheroma].

The aorta is the most frequent site for atherosclerosis, and is more frequent than the internal carotids or cerebral arteries. Transesophageal echocardiography has made it possible to identify atheromatous lesions of the aortic arch which are situated before the branches to the neck vessels and are capable of causing embolic cerebral events. These atheromatous plaques can be irregular, may protrude into the aortic lumen and sometimes have loose thrombus attached to them. The risk of strokes and transient ischemic attacks appears to be higher when plaques are more than 4 mm in thickness and when mobile components are present. Atheroma in the ascending aorta and aortic arch is a significant risk factor for cerebral ischemia, independent of high-grade carotid stenosis. Aortic atherosclerotic lesions should particularly be looked for in patients with a history of repeated peripheral and cerebral embolism, in whom no obvious embolic cause is found. A standard protocol for treatment of these potentially embolic aortic lesions has not yet been agreed upon, but the use of antiplatelet drugs or vitamin-K antagonists treatment should be considered.

[Left anterior hemiblock induced by exertion, caused by diagonal arterial stenosis: apropos of a case].

The authors report the case of a patient who developed left anterior hemiblock and ST segment depression during exercise testing which regressed during the recovery period. Coronary angiography showed severe stenosis of the diagonal artery. This conduction defect did not recur after effective angioplasty of the stenosed artery, reflecting the ischaemic nature of this abnormality.
