Title: RETROGRADE TRANSCATHETER CLOSURE OF PERIMEMBRANOUS ANEURYSMAL VENTRICULAR SEPTAL DEFECTS USING AMPLATZER VASCULAR PLUG II

Abstract:

  Retrograde transcatheter closure of perimembranous aneurysmal ventricular septal defects ( pm VSD) can be a better option due to  device placement into septal aneurysm  with fewer complications. Also retrograde approach might decrease procedure time and radiation exposure time.

Aim of the work:The purpose of our study is to report off label experience using Amplatzer Vascular Plug II for closure of perimembranous aneurysmal VSD
Material and method: Our series consist of fifteen child patient with perimembranous aneurysmal ventricular septal defect . The mean age was 4.9years (range 1.2–10), mean LVEDD 38.3 mm.  Maximum and minimum defect sizes were 4 and 8 mm by transthoracic echocardiography (mean defect size  5.2 mm). The procedure was performed under general anesthesia with left heart catheterization for retrograde closure of the defect.    Results: All subjects who met the inclusion criteria were sent to the catheterization laboratory. Following left ventricular angiogram, three patients were excluded as technically non feasible .Failure to cannulate the defect in one patient and deficient aneurysmal tissue during LV angiography in two cases. The device was successfully deployed in 12 children with retrograde technique. In two patients antegrade approach using  ADO I device for closure due to deficient aneurysmal tissue. The complete VSD closure rate was 84% immediately, 92% at 24 hours, and 92% at the last follow-up. Atrioventricular conduction system was not affected by the procedure in any patients. Arterial complication developed in two patients. There was no device embolization , no aortic regurge develop in any patient. 
Conclusions: Retrograde transcatheter closure of aneurysmal perimembrance VSDs using AVPII is safe and effective alternative method which allow closure of wider range of  VSDs due to availability of wide ranges of AVPII sizes up to 18mm  in diameter

Health: Worrying rise of hypertension in Indians

2019-10-17

Hypertension is the most important risk factor for chronic disease burden across the world. Global burden of diseases study in year 2017 reported high systolic blood pressure as the leading risk factor across the globe that accounted for 10.2 million deaths. Indians are more prone to hypertension and heart disorders, and are affected at a younger age than the Europeans. The fourth District Level Household Survey reports an overall prevalence 25.3 per cent for hypertension in India that translates to around 207 million individuals.

Hypertension in adults: summary of updated NICE guidance

2019-10-21

Hypertension is a leading global cause of morbidity and mortality. More than 25% of the adult UK population has hypertension, and in about 30% blood pressure remains uncontrolled.1 In August, the National Institute for Health and Care Excellence (NICE) published its updated guideline on the diagnosis and management of hypertension. The guideline reviews further evidence that has emerged since it was last updated in 2011 from randomised trials investigating the initiation, monitoring, and choice of antihypertensive treatment. The scope of the updated guideline has increased to also include people with type 2 diabetes, but does not make recommendations for people with chronic kidney disease, established cardiovascular disease, or hypertension in pregnancy. This article summarises the most recent recommendations from NICE and includes information considered to be most relevant to primary care clinicians. Key changes to current practice include offering drug treatment to people at a lower threshold for 10 year risk of cardiovascular disease, emphasis on maintaining blood pressure below target, and clarifying criteria for same day specialist review in people with accelerated hypertension.

Tobacco Use, Hypertension Make Rural Population Susceptible to Heart Disease

2019-11-03

A study undertaken over the course of eight years in five villages near Chennai has shown that cardiovascular diseases remain quite high even among a rural population, a report in The Hindu says. The study, carried out by Dr. Prabhdeep Kaur of Chennai’s National Institute of Epidemiology and published in the journal BMJ Open has challenged the commonly held notion that those living comparatively ‘stress-free’ lives in non-urban areas are immune to heart attacks and strokes. “The study involved 5,641 adults aged 25-64 years…There were 96 deaths — 79 from heart attacks and 17 from stroke. There were 59 adults who suffered but did not die from heart attack and stroke,” said the Hindu report.

Women with gestational hypertension have elevated cardiovascular risk later in life

2019-11-12

First, women with a history of hypertensive pregnancy had stiffer arteries and two to five times the rate of chronic hypertension later in life across age groups, compared to control subjects. Second, they were more likely to develop cardiovascular conditions over time, including coronary artery disease, which prior research suggested, heart failure, and two kinds of valvular heart disease -- aortic stenosis and mitral regurgitation -- that had not previously been associated with hypertensive pregnancy. Third, the study found that between half and one-third of the risk of coronary disease and heart failure was driven by chronic hypertension

Daily coffee can cut risk of high blood pressure and diabetes

2019-11-27

Drinking up to four coffees a day can significantly reduce the risk of type 2 diabetes, high blood pressure and obesity, according to a study. Even decaffeinated coffee gave the health boost, researchers said, though the effect from either type disappeared after four cups. The team from the universities of Navarre in Spain and Catania in Italy found that there was an “association between coffee consumption and a decreased risk of type 2 diabetes” and added that “long-term coffee consumption is associated with a decreased risk of hypertension”.
