ABSTRACT
The sinus of Valsalva presents the initial segment of the aorta from where the coronary vessels arise. Sinus of Valsalva aneurysms (SOVAs) present as progressive dilatation of the aortic sinus. SOVA arises both from the congenital and acquired weakness of the elastic lamina of the aortic media. Though most of the SOVAs are asymptomatic and diagnosed on screening for other pathologies, patients can present with symptoms of arrhythmia, aortic insufficiency, aorto-cardiac fistulas, and, in a few cases, with rupture. We describe a patient who presented with recurrent syncope and was found to have a 6 cm dilated SOVA with an ectatic ascending aorta. Further assessment revealed a left anterior fascicular block, aortic regurgitation, and mitral regurgitation. On further assessment, no other cause of syncope was found. There was no family history of aneurysm or sudden cardiac death. The patient was eventually discharged with outpatient follow-up with cardiothoracic surgery. In patients presenting with asymptomatic SOVA, a dilatation with a maximum diameter of 6.0 cm requires stringent monitoring and should be considered for surgery.
ABSTRACT
Asthma is a respiratory disorder marked by bronchial irritation and hyperresponsive airway smooth muscle. According to new research, magnesium's dual activity as an anti-inflammatory and bronchodilator may be important in asthma therapy. The goal of this study was to see how effective intravenous magnesium sulfate is in treating severe acute asthma. In addition to checking Clinicaltrials.gov, we ran a database search in Scopus, Google Scholar, PubMed, and Embase. Studies were chosen based on predetermined inclusion and exclusion criteria to prevent the chance of bias. Most researchers believed that intravenous magnesium sulfate improved symptoms and lung function significantly. Mortality and morbidity data were not available.
