Pseudoaneurysm is an uncommon and serious complication of infective endocarditis (IE). It is often fatal because of its rapid progress, high rates of rupture and recurrence, and worsening effects on the systemic condition. We report the rare case of a patient who developed a pseudoaneurysm of the sinus of Valsalva two months after emergency aortic valve replacement for active IE. At the previou...

AIMS To assess transthoracic echocardiography (TTE) using second harmonic imaging with Valsalva manoeuvre compared to transesophageal echocardiography (TEE) for the diagnosis of right to left cardiac and pulmonary shunts. METHODS AND RESULTS One hundred and ten patients referred for TEE underwent TTE with bubble contrast. Bubbles in the left atrium within three cardiac cycles were considered ...

Huge unruptured sinus of Valsalva aneurysms is rarely observed. We report a 32-year-old woman presenting with exertional dyspnea in which a giant unruptured noncoronary sinus of Valsalva aneurysm was detected after echocardiography. The aneurysm was surgically repaired and the aortic and mitral valves were replaced.

OBJECTIVE The Valsalva maneuver is recognized as an effective method to dilate the internal jugular vein (IJV). However, this maneuver cannot be performed in many cases, such as children and unconscious patients. The aim of this study was to evaluate the effectiveness of proximal IJV compression, which can easily be performed, regardless of patient cooperation. METHODS Healthy adult volunteer...

The Valsalva maneuver is a frequently used physiological test in evaluating the cardiovascular autonomic functions in human. Although a large pool of experimental data has provided substantial insights into different aspects of the mechanisms underlying the cardiovascular regulations during the Valsalva maneuver, so far a complete comprehension of these mechanisms and the interactions among the...

The cardiac output has been measured during the immediate post-Valsalva maneuver recovery period in normal subjects, patients with clinically significant mitral stenosis, and patients with alterations of the autonomic nervous system. When compared with the resting value, it was found that normal subjects had a decrease in cardiac output during the immediate post-Valsalva recovery period, while ...

While acute regurgitation is the most common valvular lesion associated with aortic sinus of Valsalva aneurysms, this report describes the pathological findings in five patients in whom primary right-sided valve dysfunction was simulated by sinus of Valsalva aneurysms. In two patients aneurysms of the noncoronary sinus projected into the right atrium at the level of the tricuspid valve and caus...
