Two-dimensional echocardiographic diagnosis of a ruptured right sinus of Valsalva aneurysm

[Multiplane transesophageal echocardiography in the preoperative evaluation of the sinus of Valsalva fistula to right chambers]

INTRODUCTION AND OBJECTIVES

Ruptured sinus of Valsalva aneurysm to right cardiac chambers is an uncommon lesion in Western countries. The prognosis is usually serious unless the condition is promptly treated surgically. For this reason an accurate anatomical and functional evaluation is necessary. The main purpose of this report is to compare the usefulness of multiplane transesophageal echocardiography with transthoracic echocardiography and angiocardiography in the preoperative evaluation of ruptured sinus of Valsalva aneurysm to right chambers.

PATIENTS AND METHOD

Since January 1990, 9 patients (mean age 36,3 18 yr, 6 males) with ruptured sinus of Valsalva aneurysm to right chambers were studied. The pathogenesis was congenital aneurysm in 6 patients, aortic prosthesis endocarditis in one and two cases of iatrogenia: during a percutaneous mitral valvuloplasty and after cardiac surgery. Transthoracic echocardiography was performed in all cases, transesophageal echocardiography in 7 and angiocardiography in 8. Two patients died before surgery, and 7 were successfully operated on.

RESULTS

Transesophageal echocardiography was more useful when compared to transthoracic echocardiography and angiocardiography in detecting: a) the fistula; b) the sinus involved; c) the right chamber affected; d) congenital aneurysms morphology and size; e) aneurysm prolapse through a ventricular septal defect, y f) the identification of other cardiac congenital or acquired anomalies.

CONCLUSIONS

Multiplane TEE is the most accurate tool in the preoperative evaluation of ruptured sinus of Valsalva aneurysm to right chambers.

Noninvasive methods in the diagnosis of ruptured aneurysm of Valsalva. Usefulness of magnetic resonance imaging and Doppler echocardiography

A ruptured aneurysm of noncoronary sinus of Valsalva was diagnosed noninvasively by magnetic resonance imaging (MRI), as well as by Doppler echocardiography. Diagnosis of this disease by MRI has not been reported previously.

Doppler and two-dimensional echocardiographic features of sinus of Valsalva aneurysm

Doppler, contrast, and two-dimensional echocardiograms of 12 aneurysms of the sinus of Valsalva in 10 consecutive patients were analyzed in order to highlight the diagnostic features. The diagnosis were confirmed by surgical and/or catheterization findings. The aneurysms had ruptured in 7 of 12 (58%). Two-dimensional echocardiography prior to the contrast studies was able to delineate the aneurysms in 7 of 12 (58%). The contrast studies outlined two additional aneurysms. The right aneurysms directed anteriorly and caudally. The noncoronary aneurysms formed an extraneous lumen at the posterior part of the aortic root, mimicking aortic dissection. Doppler examinations showed systolic and diastolic turbulence in five of six (83%) of the right aneurysms rupturing into the right ventricular outflow tract. Color Doppler echocardiography showed a left ventricular diastolic turbulence emanating from the aneurysm in a case with a noncoronary aneurysm rupturing into the left ventricle. It is concluded that the principal Doppler, contrast, and two-dimensional echocardiographic features usually allow a rapid correct diagnosis of sinus of Valsalva aneurysm.

Accurate localization of ruptured sinus of Valsalva aneurysm by real-time two-dimensional Doppler flow imaging

The surgical approach to the repair of a ruptured sinus of Valsalva aneurysm can depend on the cardiac chamber into which rupture occurs. This report details the color flow Doppler images in two patients who developed a right sinus of Valsalva aneurysm to right atrial fistula owing to bacterial endocarditis. In both cases, the color flow Doppler image was superior to contrast aortography in identifying the chamber into which rupture had occurred. The early experience with real-time two-dimensional Doppler flow imaging suggests that this noninvasive technique is valuable in the management of ruptured sinus of Valsalva aneurysms.

Doppler echocardiographic detection of a ruptured acquired aneurysm of the sinus of Valsalva. Clinical-morphologic correlations

Two-dimensional, pulsed Doppler echocardiographic and pathologic features of an unusual form of ruptured aneurysm of the sinus of Valsalva are presented. The presence of an aneurysm of the left sinus of Valsalva protruding into the left atrium complicating acute aortic valvular endocarditis was detected by two-dimensional echocardiography. Rupture of the aneurysm of the sinus of Valsalva into the left atrial cavity was suggested by pulsed Doppler echocardiography. The size and location of the site of the rupture precluded recognition by two-dimensional echocardiography or contrast angiography. This report illustrates the unique value of pulsed Doppler echocardiography to define the location and direction of intracardiac flow patterns in evaluating patients with an aneurysm of the sinus of Valsalva and suspected rupture.

An unusual echocardiographic finding in a ruptured sinus of Valsalva aneurysm

A patient with a ruptured sinus of Valsalva aneurysm (RSVA) demonstrated an unusual two-dimensional echocardiographic manifestation of this entity. A discrete mass of echoes, appearing attached to a posterior leaflet of the tricuspid valve, moved to and fro into the right ventricle during diastole and into the right atrium in systole. This echocardiographic appearance mimics a vegetation of the tricuspid valve, a flail tricuspid leaflet, a right atrial myxoma or a pedunculated right atrial thrombus. Therefore, the differential diagnosis of this echocardiographic finding should include RSVA in addition to the above mentioned disorders.

Aneurysms of sinus of Valsalva: two-dimensional echocardiographic diagnosis and recognition of rupture into the right heart cavities

The aim of this study was to evaluate the role of echocardiography in the diagnosis of sinus of Valsalva aneurysms projecting toward the right heart cavities. Three patients who had a ruptured aneurysm of a sinus of Valsalva diagnosed by echocardiography and confirmed by catheterization underwent cardiac surgery. In two patients, the aneurysm originated from the right coronary sinus and had perforated into either the inflow or outflow tract of the right ventricle. In the third patient, the aneurysm, which originated from the noncoronary sinus, ruptured into the atrium. A fourth patient was also investigated and had an unruptured aneurysm of the right coronary sinus projecting into the right ventricular outflow tract. M-mode, two-dimensional and contrast echocardiographic studies were performed before cardiac catheterization in all patients and after surgery in three patients. M-mode echocardiography was useful only when the aneurysm had an anterior projection, whether or not the aneurysm was ruptured. Conversely, two-dimensional echocardiography was always able to identify the aneurysmal sac which appeared as an abnormal circular thin-walled structure protruding into the right heart cavities. By using multiple views, it was possible to investigate the whole abnormal structure and locate the sinus from which the aneurysm originated. The use of the echo contrast technique allowed more precise definition of the aneurysmal sac and diagnosis of a left to right shunt by demonstrating a negative contrast image in the right cavities. On the other hand, no negative contrast image was recorded in the patient with an unruptured aneurysm or in the two instances of a successful surgically reconstructed aorta.

Ruptured sinus of valsalva aneurysm in children: report of two cases and literature review

Two children with ruptured sinus of Valsalva aneurysm are described, each with a ventricular septal defect, and in one there was also an associated discrete subvalvular aortic stenosis. The diagnostic appearance of two-dimensional echocardiography and axial angiocardiography are emphasized to allow early diagnosis and surgical repair. A literature review of recent reports in English disclosed that 13 patients under age 20 had been reported to have ruptured sinus of Valsalva aneurysm.
