Background:There is no established minimum data set (MDS) for cardiovascular implantable electronic devices (CIEDs), which have led to a lack of standardized assessment criteria in this field to ensure access to a reliable and coherent set of data.Objective:To establish the minimum data set of CIEDs implantation that enables consistency in data gathering, uniform data reporting and data exchange in clinical and research information systems.Methods:This descriptive and cross-sectional study was conducted in 2018. That comprised a literature review to provide an overview of cardiovascular documents, registries, guidelines and medical record forms to extract an initial draft of potential data elements then asked from experts to review the initial draft of variables to score the items according to the importance perceived by them based on a five-point Likert scale. The items scored as important or highly important by at least 75% of the experts were included in the final list of minimum data set.Results:Initial dataset were refined by experts and essential data elements was selected in eight data classes including administrative data, past medical history, sign and symptoms, physical examinations, laboratory results, procedure session, post procedure complications and discharge outcomes. For each category required variables and possible respondents where determined.Conclusions:The minimum dataset will facilitate standardized and effective data management of CIEDs implantation; and presents a platform for meaningful comparison across contexts.

I nterrupted aortic arch (IAA) is a rare congenital abnormality (incidence rate, 3 per million live births per annum). Loss of luminal continuity between the ascending and descending portions of the aorta is the main pathologic condition.1 Some cardiac malformations-including patent ductus arteriosus, ventricular septal defect, bicuspid aortic valve (BAV), left ventricular (LV) outflow tract obstruction, and aortopulmonary window-have customarily been associated with IAA.2 On the basis of the site of the lesion, 3 types of disease have been reported. In type A, arch interruption occurs distal to the origin of the left subclavian artery (this is also known as interruption at the aortic isthmus). In type B, the lesion is distal to the origin of the left common carotid artery; and in type C, the interruption is between the common carotid arteries.3 Because of the high mortality rate-75% by 10 days and 90% at 12 months of life (without surgical correction in infancy)-IAA is very rare among adults. 2,3 In this report, we describe the case of a 76-year-old woman with asymptomatic IAA, severe tricuspid regurgitation (TR), and BAV, a perhaps unique combination of pathologic conditions that no one, to our knowledge, has reported before. Case ReportIn August 2014, a 76-year-old woman was referred to our department for dyspnea on exertion (New York Heart Association functional class II), which had begun one month before referral. No other relevant information was found in her medical history. Upon physical examination, her peripheral pulses were palpable symmetrically, over the carotid arteries and in the upper limbs. We heard a machine-like murmur over the right scapula and a soft systolic murmur over the left sternal border space. Lower-limb pulses were not palpable. Chest radiographs revealed no pathologic abnormalities. An electrocardiogram showed sinus rhythm and right bundle branch block.Transthoracic echocardiography revealed a normal LV ejection fraction (0.55), severe right ventricular dysfunction, BAV, mild aortic valve regurgitation, and severe tricuspid valve regurgitation (pulmonary artery pressure, 40 mmHg). Coronary angiography was performed via a right radial artery approach. The left anterior descending artery and the right coronary artery had significant stenoses. Aortography showed enlargement of the ascending aorta, BAV, normal aortic arch dimensions, and occlusion of the aorta immediately distal to the origin of the left subclavian artery (Fig. 1). Computed tomographic (CT) angiographic findings were compatible

BACKGROUND Upper gastrointestinal bleeding (UGIB) is a major healthcare problem and is the most frequent gastrointestinal reason for admission to hospital. We aimed to investigate the prognosis of patients with UGIB referred to a referral hospital in northern Iran in 2013. METHODS All patients with UGIB who admitted to Sayyad Shirazi Hospital, in Gorgan, northern Iran, in 2013 were enrolled. The patients’ demographic data as well as data about admission, diseases, drug history, and patients’ prognosis were collected by structured questionnaire using information in hospital files. The relationships between different factors with the proportion of mortality and recurrence were assessed using Chi-square test. RESULTS In total, 168 patients were enrolled of whom 109 (64.9%) were male. The mean (SD) age of the patients was 59.4 (18.2) years. Mortality and recurrence occurred in 23.2% and 34.5% of the subjects, respectively. We found significant relationships between older age and diagnosis of malignancy with mortality (p =0.03 and p <0.01) and recurrence (p<0.01 and p <0.01). CONCLUSION We found relatively high rates of mortality and recurrence among patients with UGIB. Our results suggested older age and diagnosis of malignancy as the most important indicators of mortality and recurrence in such patients. Considering these factors in clinical settings may result in better and more effective management of patients with UGIB.
