We report the case of a 42-year-old female referred to our institution for an incidental diagnosis of an aortic aneurysm. Multislice 64-CT angiography showed a giant aneurysm of the Valsalva sinus, which extended to all three coronary arteries, and multiple aneurysms along the entire length of the coronaryarteries (Panels A–C ). The Valsalva sinus aneurysm was eccentric, more pronounced near th...

OBJECTIVES The sinuses of Valsalva are known to contribute to the normal function of the aortic valve. Little is known about their role in promoting coronary artery blood flow. The aim of this study was to compare coronary artery flow characteristics among patients undergoing a Bentall operation by means of a conventional cylindrical Dacron conduit or with a new conduit with pseudosinuses of Va...

OBJECTIVE This study was designed to define the degree of stretch/strain required of the levator hiatus in childbirth. There have been attempts at defining the distension required for vaginal childbirth with the help of individual data sets, but from previous work it is clear that hiatal dimensions and distensibility are likely to vary greatly between individuals. DESIGN Retrospective observa...

BACKGROUND AND PURPOSE Right-to-left shunt (RLS) via the patent foramen ovale is an important cause of cryptogenic stroke. The Valsalva maneuver provokes or enhances RLS, but RLS can also occur during normal respiration. This study examined whether the ischemic lesion pattern differs depending on the character of RLS. METHODS All consecutive patients with a patent foramen ovale (diagnosed by ...

Autosomal dominant polycystic kidney disease (ADPKD) is associated with vascular aneurysms that can affect any part of the vascular tree, like ascending aorta or coronary arteries. Sinus of Valsalva is known as an anatomical dilation at the root of aorta above the aortic valve and very few cases show aneurysm at that site in patients with ADPKD. Sinus of Valsalva aneurysm (SVA) can present with...

It is often challenging to assess cardiac filling pressure clinically. An improved system for detecting or ruling out elevated cardiac filling pressure may help reduce hospitalizations for heart failure. The blood pressure response to the Valsalva maneuver reflects left heart filling pressure, but its underuse clinically may be due in part to lack of continuous blood pressure recording along wi...

Occasionally, lifting of a heavy weight leads to dizziness and even to fainting, suggesting that, especially in the standing position, expiratory straining compromises cerebral perfusion. In 10 subjects, the middle cerebral artery mean blood velocity (V(mean)) was evaluated during a Valsalva maneuver (mouth pressure 40 mmHg for 15 s) both in the supine and in the standing position. During stand...

The Valsalva maneuver was performed during cardiac catheterization in 9 patients who had undergone a Fontan operation (Fontan group) and in 10 control subjects. The Fontan group had higher right atrial (RA) pressure (16 f 1 vs 4 f 0.5 mm Hg, p <O.OOi), lower cardiac index (2.5 f 0.1 vs 3.7 f 0.2 liters/min/m*, p <0.05), lower stroke index (32 f 2 vs 44 f 2 ml/beat/m*, p <0.05), and higher syste...

This study evaluated the efficacy of the valsalva maneuver that can induce baroreceptor activation and nociception, on needle projection pain and hemodynamic responses associated with spinal puncture. Ninety adults, ASA physical status I and II undergoing elective surgeries were included. Patients were randomized into three equal groups. Group I (C): control; Group II (B): ball; pressed a rubbe...

In the present study, we assessed whether elevated (> or =15 mmHg) PCWP (pulmonary capillary wedge pressure) can be detected using the blood pressure response to the Valsalva manoeuvre in a group of elderly patients with various cardiac disorders, including atrial fibrillation and valvular heart disease, and healthy elderly controls. The Valsalva manoeuvre was performed in 93 patients (71+/-4 y...
