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.

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 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 ...

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.

2025年2月10日 · Displays battery life, impeller RPM, cardiac output & power usage. Alarms are also displayed here. A typical CXR for a patient with an implanted left ventricular assist device. These patients will often have pacemakers or AICDs …

Right internal jugular central venous catheter, endotracheal tube, enteric tube, triple lead left chest AICD and Impella left ventricular assist device (LVAD) all project in appropriate locations. ECG leads and defibrillator pads overlie the patient. The coronary artery stent is …

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.

2013年6月1日 · VAs were defined as ventricular tachycardia (VT) or ventricular fibrillation (VF) detected by ICD interrogation, telemetry, or ECG and lasting ≥30 s or requiring defibrillation or antitachycardia pacing. A total of 32 patients (35%) had VA after LVAD implant.
