We report the first ultrasonographically guided percutaneous balloon atrial septoplasty (BAS), to our knowledge, in a fetus with transposition of the great arteries and an intact ventricular and atrial septum (37 + 2 weeks). After vaginal delivery at 38 weeks, the infant had an elective septostomy (day 1) and an arterial switch procedure (day 7), with an uneventful postoperative course. For centres with experience in fetal cardiac interventions, fetal BAS is a superior management option compared with the alternatives for this high-risk physiology. 相似文献

Spontaneous coronary artery dissection is an important etiology of nonatherosclerotic acute coronary syndrome, myocardial infarction, and sudden death. Innovations in the catheterization laboratory including optical coherence tomography and intravascular ultrasound have enhanced the ability to visualize intimal disruption and intramural hematoma associated with SCAD. Formerly considered “rare,” these technological advances and heightened awareness suggest that SCAD is more prevalent than prior estimates. SCAD is associated with female sex, young age, extreme emotional stress, or extreme exertion, pregnancy, and fibromuscular dysplasia. The clinical characteristics and management strategies of SCAD patients are different than for atherosclerotic heart disease and deserve specific consideration. This review will highlight recent discoveries about SCAD as well as describe current efforts to elucidate remaining gaps in knowledge. 相似文献

Aneurysms arising from the sinus of Valsalva are a rare cardiac defect that can present with various signs and symptoms, and if not diagnosed and treated rapidly can lead to fatal outcomes. Unruptured aneurysms are usually asymptomatic and found incidentally during diagnostic studies. More commonly, aneurysm of sinus of Valsalva is detected after the occurrence of rupture. Echocardiography has become the investigative tool of choice for this condition, not only for diagnosis but also for quantification of severity. We hereby report a rare case of a 15‐year‐old patient presenting with complaints of effort dyspnea and palpitations. Two‐dimensional transthoracic echocardiography (TTE) showed aneurysmal dilatation of left sinus of Valsalva which had ruptured into the left ventricle. Also, there was an intimal flap within the sinus of Valsalva aneurysm. The anatomical relationship between the aorta, aneurysm, and the left ventricle as well as the intimal flap within the aneurysm was clearly delineated with the help of three‐dimensional TTE. After confirmation of the diagnosis with multidetector computed tomography, patient underwent successful surgical repair of the defect. 相似文献

To perform sputum analysis for verification of pulmonary changes in premenopausal rural Indian women chronically exposed to biomass smoke during cooking.Three consecutive morning sputum samples were collected from 196 women (median age 34 years) cooking with biomass and 149 age-matched control women cooking with cleaner fuel liquefied petroleum gas. Smears made on slides were stained with Papanicolaou and Perl's Prussian blue. Airway oxidative stress was estimated as reactive oxygen species (ROS) generation (by flow cytometry) and superoxide dismutase (SOD) level (by spectrophotometry) in sputum cells. Airway inflammation was measured as sputum levels of interleukin (IL)-6, -8 and tumor necrosis factor- alpha (TNF-α). Particulate matter of diameter less than 10 (PM10) was measured using laser photometer while benzene exposure was monitored by measuring trans, trans-muconic acid (t,t-MA) in urine by HPLC-UV. Compared with control, sputum of biomass users contained more neutrophils, lymphocytes, eosinophils, alveolar macrophages, and showed presence of ciliocytophthoria, Charcot-Leyden crystals, Curschmann's spiral. ROS generation was increased by 2-fold while SOD was depleted by 31% in biomass users. They also had higher sputum levels of IL-6, -8 and TNF-α. Levels of PM10 and t,t-MA were 2.9- and 5.8-times higher in biomass-using women. PM10 and t,t-MA levels were positively associated with cellular changes in the sputum, markers of airway inflammation, and oxidative stress. Cooking with biomass alters sputum cytology, and increases airway inflammation and oxidative stress that might result in further amplification of the tissue damaging cascade in women chronically exposed to biomass smoke. 相似文献
