A 38-year-old man with a history of recurrent genital ulceration initially diagnosed as genital herpes was admitted after presenting with paroxysmal nocturnal dyspnea. Echocardiography revealed aneurysm formation of the sinus of Valsalva. On diagnosis of an aneurysm of the sinus of Valsalva associated with Behçet's disease (BD), surgeon repaired the affected sinus only, and continuous steroid t...
STUDY OBJECTIVES The objectives of this study were (1) to assess the prevalence of patent foramen ovale (PFO) by means of contrast transesophageal echocardiography (TEE) in patients with obstructive sleep apnea, and (2) to determine the potential contribution of right to left interatrial shunting to systemic oxygen desaturation following the performance of Valsalva maneuver. DESIGN Performanc...
Background and Aims: To assess the difficulties encountered while performing coronary angiography percutaneous intervention in anomalous right artery arising from left sinus of Valsalva.
 Methods: Between January 2016 December 2020, a total 23 patients underwent eight for an angiographic significant lesion Valsalva. The vascular approach, usage catheters, fluoroscopic time, amount contrast...
PURPOSE To evaluate changes at the anterior chamber angle during Valsalva maneuver in eyes suspected to have a primary adult glaucoma. METHODS Seventy-six consecutive patients underwent recording of applanation tonometry, measurement of the anterior chamber angle recess, angle opening distance, angle recess area, scleral spur-iris root distance, iris thickness, iridociliary angle, ciliary bod...
Introduction: Spontaneous pneumomediastinum (SP) is the accumulation of air in mediastinum without a surgical or traumatic etiology. It thought that basic mechanism triggering SP pressure difference develops after strong Valsalva maneuver.
 Case report: We presented 50-year-old male patient was admitted to emergency department with sudden onset chest and epigastric pain started standing up...
Introduction: Valsalva retinopathy is a unilateral or bilateral condition that occurs when increased intra-thoracic or intra-abdominal pressure transmitted to the eye causes a sharp rise in the intraocular venous pressure, and rupture of superficial retinal capillaries. The patient often gives a history of a recent strenuous physical act, which could have increased the intra-thoracic pressure. ...
The association of sinuses of Valsalva dilatation and aortic regurgitation with hypertension is disputed, and few data are available in population-based samples. We explored the relations of sinuses of Valsalva dilatation and aortic regurgitation to hypertension and additional clinical and echocardiographic data in 2096 hypertensive and 361 normotensive participants in the Hypertension Genetic ...
A case is reported in which a congenital aneurysm of the right coronary sinus of Valsalva ruptured and dissected into the interventricular septum. M-mode and cross-sectional echocardiographic examination allowed accurate preoperative assessment of the pathologic anatomy, which was confirmed by angiography, surgery and autopsy. Dissection of the interventricular septum by a congenital sinus of V...
A patient who had endocarditis on a prosthetic aortic valve and who had undergone two aortic valvular replacements developed classic angina pectoris. Cardiac catheterization revealed an aneurysm of the left sinus of Valsalva, which constricted a proximal segment of the left circumflex coronary artery during systole. This type of dynamic coronary arterial narrowing has not been previously descri...
Aneurysm of the left sinus of Valsalva is rare, and there is only one previous report of rupture into the pulmonary artery. This report describes a patient with valvular pulmonary atresia and ventricular septal defect in whom a portion of his pulmonary blood flow was supplied by an aortopulmonary tunnel arising from a left sinus of Valsalva aneurysm. The surgical implications of precise definit...
