Non-penetrating chest trauma commonly causes a wide variety of cardiac injuries. Disruption of the aortic valve with resultant aortic regurgitation is not uncommon; conversely, a sinus of Valsalva-right atrial fistula, in the absence of a congenital sinus of Valsalva aneurysm, has been reported only once previously. This report describes the detection by preoperative cardiac catheterisation of ...
A ruptured sinus of Valsalva aneurysm rarely accompanies the aortic and tricuspid valve endocarditis. A 36-year-old woman presented with low-threshold dyspnea on exertion and fever. Transthoracic and transesophageal echocardiography showed a ruptured noncoronary sinus of Valsalva aneurysm with large vegetations on the tricuspid and aortic valves, resulting in moderately severe tricuspid regurgi...
Background and purpose: One of the major complications of diabetes is retinopathy which is a highly specific vascular complication of type I and II diabetes. This study aimed at investigating the factors influencing the diagnosis of retinopathy in patients with type II diabetes using Cox, parametric, exponential, weibull, Log normal, and Log-logistic models and comparing their functions Mat...
Aneurysm of sinus of Valsalva is a rare anomaly which can be congenital or acquired. The right coronary sinus is the commonest site of aneurysm formation, with only a few cases reported to arise from the left coronary sinus. Although most patients with unruptured aneurysm of sinus of Valsalva are asymptomatic, fatal complications of unruptured aneurysms of sinus of Valsalva have been reported. ...
Sinus of Valsalva aneurysm can be congenital or acquired. The major complication is rupture: this can represent an evolution or an abrupt event. In case of rupture or of large aneurysm, a surgical approach is justified. We report a case of ruptured sinus of Valsalva aneurysm in a seventeen years old girl, who had underwent surgical correction of Fallot tetralogy. As soon as the rupture of sinus...
background :although laparoscopic cholecystectomy is associated with less post-operative pain compared to open cholecystectomy, diffuse shoulder and abdominal pain is one of the main postoperative complications in this technique. the aim of this study was to compare the abdominal and shoulder pain after laparoscopic cholecystectomy by applying intra-abdomin...
cardiac anomaly (1). SVA most commonly originates in the right coronary sinus of Valsalva (75-90%), the noncoronary sinus (10-25%), and rarely, in the left sinus (1, 2). Unruptured SVA usually remains asymptomatic, but it can sometimes cause cardiac arrhythmia, myocardial ischemia, or systemic embolic events (1-3). Multidetector computed tomography (MDCT) is a useful modality for examining the ...
A sinus of Valsalva aneurysm is a rare malformation of the aortic root that can fistulize to another cardiac structure such as the right atrium. Although transthoracic echocardiography and computed tomography angiography have demonstrated utility for the diagnosis of a sinus of Valsalva-to-right atrial fistula, there are few cases where a misdiagnosis may occur. Intraoperative transesophageal e...
PURPOSE Premacular subhyaloid hemorrhage is usually a benign condition that generally improves spontaneously and rarely causes visual loss. However, because the hemorrhage may cause permanent macular changes before it resolves, Nd:YAG laser posterior hyaloidotomy may be indicated in selected cases. This study investigated the effects of drainage of premacular subhyaloid hemorrhage into the vitr...
Respiratory effort during inspiration, expiration, and the Valsalva manoeuvre changes right ventricular preload and afterload. On inspiration these changes should improve systolic emptying of a larger end diastolic volume and so increase the ejection fraction, whereas on expiration the reverse should be true. The resting right ventricular ejection fraction was measured by first pass radionuclid...
