Societal views of pacemaker reutilization for those with untreated symptomatic bradycardia in underserved nations

Abstract: Significant healthcare disparities exist between the developed world and low and middle income countries (LMIC), specifically in the field of cardiac electrophysiology. As a result, pacemaker reutilization has been proposed as a viable option for those in LMIC and no other means of obtaining a device. Little data exist regarding the feasibility of establishing a reuse program in addition to understanding the views of society on device reutilization. This study investigated the views of funeral directors, patients with cardiac devices, and members of the general population regarding reutilization of previously implanted pacemakers. Ninety funeral directors in Michigan were surveyed regarding current practice as well as preferences for post-mortem device disposal. One hundred and fourteen patients with devices and 1,009 members of the general population were surveyed regarding post-mortem device handling. Funeral directors had an average of 21 years of experience with an annual volume of 120 deceased persons per year, with a cremation rate of 35%. When asked about disposal methods of explanted devices, the majority of devices (84%) were discarded as medical waste or stored with no intended purpose, with a total of 171 devices currently in possession at the funeral homes. Eighty-nine percent of funeral directors expressed a desire to donate devices for reuse in LMIC and 10% acknowledged previous device donation. Eighty-seven percent of device patients and 71% of the general population also expressed a desire to donate devices. The results of our survey show that a large percentage of funeral directors, patients with implantable devices, and members of the general population support a pacemaker reutilization initiative. This study lends further evidence that collection of devices for reuse is feasible and that establishing a framework for regional pacemaker reutilization program is warranted. If successful, the feasibility of this model should be investigated in other parts of the country in order to alleviate the burden of untreated symptomatic bradycardia in our world.

Update in the Management of Aortic Dissection

Abstract: Recent improvements in diagnosis, peri-operative management, surgical techniques and postoperative care have resulted in decreased mortality and morbidity in acute aortic dissections (AAD). The classic treatment algorithm indicates that type A patients require direct surgical intervention and type B patients should be treated medically, in absence of complications. Initial medical treatment is adopted in all AAD patients, as it reduces propagation of the dissection and aortic rupture. In type A aortic dissection (TAAD) several techniques have contributed to major changes in the surgical approach, such as cerebral protection using moderate circulatory arrest, selective cerebral perfusion, and aortic valve sparing with root replacement. In TAAD with involvement of the descending aorta, thoracic endovascular aortic repair (TEVAR) can be performed as a part of a complex hybrid procedure, in which surgical ascending/arch repair is combined with the placement of a stent graft in the descending aorta. Future developments in stent graft technologies might broaden the usefulness of TEVAR for the total endovascular repair of TAAD. In complicated type B aortic dissection (TBAD), the use of TEVAR has become the therapy of first choice. By covering the proximal entry tear, the stent graft reduces the pressurization of the false lumen, treating malperfusion and inducing favorable aortic remodeling. In uncomplicated TBAD, TEVAR has been used to prevent long term complications, such as aortic aneurysm, but this concept is not yet routinely recommended. Regardless of their initial treatment, all AAD patients should be administered with strict antihypertensive management combined with imaging surveillance and careful periodic clinical follow-up.

Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure

Abstract: The National High Blood Pressure Education Program presents the complete Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure. Like its predecessors, the purpose is to provide an evidence-based approach to the prevention and management of hypertension. The key messages of this report are these: in those older than age 50, systolic blood pressure (BP) of greater than 140 mm Hg is a more important cardiovascular disease (CVD) risk factor than diastolic BP; beginning at 115/75 mm Hg, CVD risk doubles for each increment of 20/10 mm Hg; those who are normotensive at 55 years of age will have a 90% lifetime risk of developing hypertension; prehypertensive individuals (systolic BP 120-139 mm Hg or diastolic BP 80-89 mm Hg) require health-promoting lifestyle modifications to prevent the progressive rise in blood pressure and CVD; for uncomplicated hypertension, thiazide diuretic should be used in drug treatment for most, either alone or combined with drugs from other classes; this report delineates specific high-risk conditions that are compelling indications for the use of other antihypertensive drug classes (angiotensin-converting enzyme inhibitors, angiotensin-receptor blockers, beta-blockers, calcium channel blockers); two or more antihypertensive medications will be required to achieve goal BP (<140/90 mm Hg, or <130/80 mm Hg) for patients with diabetes and chronic kidney disease; for patients whose BP is more than 20 mm Hg above the systolic BP goal or more than 10 mm Hg above the diastolic BP goal, initiation of therapy using two agents, one of which usually will be a thiazide diuretic, should be considered; regardless of therapy or care, hypertension will be controlled only if patients are motivated to stay on their treatment plan. Positive experiences, trust in the clinician, and empathy improve patient motivation and satisfaction. This report serves as a guide, and the committee continues to recognize that the responsible physician's judgment remains paramount.

Recommendations for cardiac chamber quantification by echocardiography in adults: an update from the American Society of Echocardiography and the European Association of Cardiovascular Imaging.

Abstract: The rapid technological developments of the past decade and the changes in echocardiographic practice brought about by these developments have resulted in the need for updated recommendations to the previously published guidelines for cardiac chamber quantification, which was the goal of the joint writing group assembled by the American Society of Echocardiography and the European Association of Cardiovascular Imaging. This document provides updated normal values for all four cardiac chambers, including three-dimensional echocardiography and myocardial deformation, when possible, on the basis of considerably larger numbers of normal subjects, compiled from multiple databases. In addition, this document attempts to eliminate several minor discrepancies that existed between previously published guidelines.
