Indications for catheter intervention include symptoms of fatigue and exercise intolerance buspirone 5 mg low cost anxiety quotes, symptoms which often are experienced with increased age order buspirone online from canada anxiety jealousy, even with stable stenosis buy 5 mg buspirone overnight delivery anxiety symptoms postpartum. Severe pulmonary stenosis can be successfully treated by catheter-based balloon angioplasty. Surgical valvotomy is reserved for patients in whom balloon valvulo- plasty has been unsuccessful or for patients in whom multiple levels of obstruction are demonstrated. Critical pulmonary stenosis requires prompt initiation of prostaglandin infusion to maintain ductal patency and provide pulmonary blood flow. Following complete echocardiographic assessment, most neonates proceed to the cardiac catheterization laboratory for balloon valvuloplasty, after which the prostaglandin infusion is dis- continued. Occasionally, infundibular stenosis becomes apparent following balloon valvuloplasty, and a surgical Gore-tex shunt is required to maintain pulmonary blood flow. Though pulmonary valve patency has been established, many neonates continue to demonstrate moderate cyanosis, with SpO2 of 70 80%, which improves slowly over several months as the right ventricular compliance improves and decreases the degree of right to left atrial level shunt. An infant with a history of critical or severe pulmonary stenosis and pulmonary valvuloplasty requires pulse oximetry assessment at each visit. In the rare instance of isolated infundibular stenosis, patch widening of the right ventricular outflow tract and resection of the infundibular muscle are required. Treatment for supravalvular and branch pulmonary artery stenosis includes fre- quent medical observation. Catheter intervention is indicated following the onset and/or progression of symptoms. Surgical pericardial or prosthetic patch augmenta- tion is indicated for severe stenosis not amenable to catheter-based interventions. However, most patients undergo serial balloon angioplasty catheter interventions with the hope of modifying disease progression. Patients with diffuse arteriopathy are at increased risk for sudden death with procedural sedation and anesthesia, and should therefore be referred for cardiology evaluation before any procedures or surgeries. In accordance with the most recent recommendations by the American Heart Association, subacute bacterial endocarditis prophylaxis is no longer indicated for 10 Pulmonary Stenosis 141 isolated pulmonary stenosis. If pulmonary stenosis is associated with a right-to-left atrial shunt, or if associated with surgical or transcatheter prosthetic material, then subacute bacterial endocarditis prophylaxis should be provided as long as there is a residual lesion. Case Scenarios Case 1A A 1-day-old infant born at 40 2/7 weeks gestation develops cyanosis without respiratory distress at 24 h of life. On examination, she is awake, cyanotic, and tachypneic with a respiratory rate in the 60 s. On auscultation, lung sounds are clear and heart tones are normal, without a click or a distinct P2 component. Discussion This history is typical of an infant with ductal-dependent pulmonary blood flow. The infant requires prompt initiation of prostaglandin infusion to maintain ductal patency. Oxygen administration does not improve the saturation because blood delivery to the lungs is compromised in the setting of obstructed pulmonary outflow and a closing ductus arteriosus. A chest radiograph, electrocardiogram, and echocardiogram can be performed to establish the diagnosis of critical pulmonary stenosis, following initia- tion of prostaglandin infusion. The differential diagnosis includes a variety of con- genital heart lesions which include severe or critical pulmonary stenosis such as tetralogy of Fallow with severe pulmonary stenosis. On the other hand, lesions with tricuspid or pulmonary atresia are unlikely to present in this fashion since these are ductal-dependent lesions, which would provide increase in pulmonary blood flow and restriction or closure of the ductus arteriosus would result in severe and life-threatening deterioration due to acute drop in blood flow to the lungs. Chest X-ray: In this infant, the cardiac silhouette is normal, without evidence of cardiac enlargement (Fig. Though many infants with critical pulmonary stenosis have right atrial enlargement and cardiomegaly on chest radiograph, the diagnosis can still be suggested in infants without cardiomegaly by noting the dark lung fields which occur as a result of reduced pulmonary blood flow. Echocardiography: An echocardiogram confirms the diagnosis of critical pul- monary stenosis with a patent ductus arteriosus supplying pulmonary blood flow to good-sized branch pulmonary arteries. The pulmonary vasculature is reduced suggestive of reduced pulmonary blood flow with no demonstrable flow across the valve. The right ventricle is hypertrophied with a small chamber size, and it contracts poorly. The interventricular septum bows into the left ventricle, suggesting the right ventricular pressure is greater than the left. Cardiac catheterization: The infant is taken to the cardiac catheterization labo- ratory, where a catheter is advanced from the right femoral vein to the right atrium and then manipulated into the right ventricle. The measured right ventricular sys- tolic pressure is 123 mmHg, compared with a systolic blood pressure of 74 mmHg. An angiogram is performed, which demonstrates a tiny blow-hole in the pulmo- nary valve, thereby distinguishing pulmonary valve stenosis from atresia. A guidewire is advanced from the femoral vein to the right atrium, and then manipulated across the tricuspid valve and the pulmonary valve, to the ductus arteriosus and down the descending aorta. The balloon is tracked over the guidewire and positioned across the pulmonary valve. Note that as the balloon is inflated (a), the waist of the balloon disappears (white arrows) as it opens the valve and relieves the stenosis (b) Pulse oximetry at the start of the procedure was 80% in room air, with continuous prostaglandin infusion. The right ventricular systolic pressure is now down to 45 mmHg, compared with a systolic blood pressure of 68 mmHg. Since the last visit at 1 month of age, the infant has been feeding and acting normally. The precordium is hyperdynamic, and a thrill is pal- pable at the left upper sternal border. An audible click is present at the left upper sternal border, along with a 4/6 harsh ejection-quality (crescendo decrescendo) mur- mur which radiates to the back and bilateral axillae. Discussion The pulmonary stenosis in this infant has progressed following the initial valvulo- plasty, and requires repeat valvuloplasty. Though valvular pulmonary stenosis usually improves with time, infants with critical pulmonary stenosis may experience initially progressive disease and require reintervention. Case 2 A 15-year-old girl with Williams syndrome has relocated from another city and presents for a required routine examination prior to enrollment at her new school. Her medical history is significant for a cardiology evaluation at the time of her genetic diagnosis as an infant, which was normal. Her mother identifies the young- ster being sedentary and overweight as her two main concerns. She seems to have reasonable exercise tolerance and has no complaints of shortness of breath, syncope, chest pain, or abnormal skin coloring. On examination, the patient is polite and pleasant, demonstrating the typical features of Williams syndrome. On cardiac examination, increase in the right ventricular impulse at the left lower sternal border is noted. No murmurs are audible in the chest or back, though the exam may be compromised by the patient s body habitus. Bibasilar interstitial and patchy air space disease is present Chest X-ray: A chest radiograph is performed (Fig.

The senior needs to be aware of the meetings/ forums where finance is discussed so that the health advisers are represented Are there local investment or development plans that are relevant? It is important to focus on social or cultural changes and what the implications there are for the health adviser team: Are different cultural groups beginning to access the service? Implications of changes in lifestyle identified in reports order buspirone us anxiety symptoms tight chest, that may affect the way the team works How to manage an increasing workload of patients and how to prioritise the workload What are the health and education needs of the attendees? There needs to be foresight into possible technological changes on the organisation and team discount 10 mg buspirone otc anxiety when trying to sleep. For example buy buspirone uk anxiety 6 weeks pregnant, changing to more sensitive chlamydia screening tests so that more patients with chlamydia are diagnosed. How will the clinic cope with the increase in work and referrals or requests for advice from the community? T analysis helps the health adviser/ manager (and the team) think about the future and look at potential changes and formulate a picture of what the team needs to be working on. The senior must be mindful not to censor people s responses and write all of the suggestions down. The senior can also introduce their ideas (without it meaning that everyone has to do what the senior thinks). Using individual flip charts or headings on a computer projector ask the team the following questions. At the end of this exercise another sheet of paper can be used entitled a 5 year plan and the team asked to brainstorm the next 5 years. Questions such as What could the team improve on in each of these areas in the next five years? It is important to focus the 5 year work plan into what could ideally be achieved in this coming year. Using the 5 year list ask the team to come up with the ten (5-20 dependant on the size of the tasks and the size of the team) things the team need to do. The manager needs to integrate the organisational or team goals with personal goals of the individual health adviser. As a senior health adviser/ manager it is important to look at the following expectations: What does the senior wish the team to achieve? What courses are health advisers going to do, and how does their learning fit into the role? The objectives need to be delegated to all members of the team including the senior. It is also important for the manager to look at what support/ training needs/ appropriate supervision and support will need to be given to the health adviser so that they can do their task. It is important to: Write up the exercise promptly and circulate to the team (see example fig. This will help inform the manager of the teams plans for development and may improve the visibility around the health adviser s role. It may be a good way of selling the potential of the team, their good ideas, and it helps managers understand what the team is trying to achieve. Objective setting needs to be an annual process so it is important that the senior health adviser/ manager looks at ways that the process could be sabotaged by the team or themselves: Sabotage: Individuals may try to sabotage the process. Consider speaking to anyone who is likely to sabotage the process to minimise any possible disruption Negativity: It is important that the senior leads this process, is not too negative, is enthusiastic and thinks about how the session will be run. It is a continually evolving process Time: It is important the team have protected time. The meeting has to start on time and the senior makes sure that the health advisers are reminded Creativity: It is important to think laterally. It is important that the senior/ manager avoids being dictatorial and motivates the team to develop their ideas Table 25. Most managers will be expected to attend a study day on performance reviews and there are often corporate forms to be used and interview assessment tools. The person s individual objectives are used as a focus of the individuals work performance. Once the individual performance plan has been set and agreed then it needs to be reviewed regularly as part of the health adviser s supervision. Setting individual objectives may be facilitated by an individual appraisal (see Appendix 2, an example of a health adviser questionnaire/ interview tool). Using the tool set out before or a Trust questionnaire, this may need slight modification so it is relevant to the role. The questionnaire is a start point, a clarification or review tool for the health adviser, which asks the health adviser what targets or objectives they would suggest for themselves (see question 11). If there is some resistance then meet with the individual and go through the questions with them making a note of the answers. Going through the questionnaire and discussing possible objectives may take 60-90 minutes. If the session goes on longer it is best to rebook the finalising of the objectives. After the session the health adviser will need time to update their questions and develop their objectives. Review objectives prior to the meeting 239 The senior/ manager needs to have the relevant leave forms/ rotas at hand to look at annual or study leave requests The senior/ manager needs to have the relevant paperwork, for example their objectives to hand Checklist How are things? Does the senior/ manager have any concerns about the health adviser s work or performance in the team, for example lateness. If there is an issue the senior/ manager needs to give clear guidance/ boundaries on what their concern is and what is expected to change and why Any concerns in the health adviser team or clinic team? If there are it is important to make it clear what the managers perspective is, giving guidance/ boundaries of what is acceptable and what is not. Decide on any action that needs to be taken and if so make it explicit what needs to be done by the health adviser to achieve the action Discuss their patients. Review the individual s patient workload, for example how many ongoing patients and how many sessions, whether the cases are being supervised and whether there are any management issues that the manager needs to be aware of. It is important to be clear about the differing roles and boundaries between the role of the clinical supervisor and that of the manager, for example the management session need not spend time focusing on a patient. If there are specific patient management issues, for example when the clinical supervisor has suggested that the health adviser discuss an ethical dilemma with the manager to get their viewpoint, then it is important to arrange a separate time to focus on the issue Leave. Review annual leave/ study leave and where time owing is allowed that this is reviewed and managed Study leave. Revisit and review objectives, going through each objective and look at how the work is progressing. Does your job description accurately describe your main duties and responsibilities?
