2024年1月24日 · Ventricular assist devices (VAD) are a mechanical circulatory support device, which is providing an effective therapy for a significant number of patients with advanced heart failure. There are mostly left VADs, although right VADs are also implanted.

2024年8月28日 · Left ventricular assist devices (LVAD) are mechanical circulatory support device that are surgically implanted to aid in pumping blood in patients with severe refractory cardiac failure. It may be used as a bridge to heart transplantation, or as destination therapy in patients who are not a transplant candidate.

2018年12月1日 · There are two types of cardiac conduction devices (CCD's): Pacemakers that pace the heart during periods of bradycardia. Inplantable cardioverter-defibrillators (ICD's) that are capable of defibrillating the heart to prevent cardiac arrest. Pacemakers can have leads, that pace: Right atrium - tip of lead is located in atrial appendage.

2024年8月28日 · Temporary ventricular assist devices (or temporary VADs) are temporary percutaneous devices used in supporting a failing heart in cardiogenic shock or perioperatively. Temporary VADs consist of an inlet, outlet and impeller pump all housed within a catheter. Temporary VADs are inserted percutaneously usually via the femoral artery.

The role of the radiologist involves identifying the device on the CXR, as well as careful assessment for accurate placement and excluding complications. The intention of this article is to provide insight into the various VADs found in clinical practice, identifying the most commonly used types, assessing their placement and highlighting ...

The chest radiograph (CXR) is an important diagnostic tool for VAD patients. Direct visualization of VAD positioning as well as presence/absence of ICD aids the emergency physician in baseline evaluation.

The chest radiograph, or chest X-ray (CXR), is a well-established imaging modality that is widely used to check for lung, pleural and mediastinal abnormalities [1]. In addition, it is also a first-line examination to monitor the correct positioning of medical devices.

Background: Venous access device (VAD) occlusion from intraluminal thrombus is a common complication during childhood cancer treatment. Current practice at many institutions is to assess VAD position with a chest X-ray (CXR) prior to intraluminal …

2023年5月3日 · A ventricular assist device (VAD) is a device that helps pump blood from the lower chambers of the heart to the rest of the body. It's a treatment for a weakened heart or heart failure. A VAD may be used to help the heart work while waiting for other treatments, such as a heart transplant.

2023年9月21日 · 您应该在 cxr 上寻找三个不同的东西： 白色=高吸收=骨头. 灰白色 = 中等吸收 = 液体/组织. 黑色=低吸收=空气. 胸部 x 光检查的技术充足性. 在解释之前，应评估 cxr 的技术充分性，并考虑以下因素： 确定这是正确的患者
