Signs of LVAD Dysfunction: •Right‐shift of the IVS and LV enlargement •AoValve opening with every beat (9‐10/10 beats) •Blunted flow through both cannulas (PW/CW Doppler) •RAMP studies (lack of LV dimensions change with increase in pump support/RPM) A …

This guideline addresses the role of echocardiography during the different phases of care of patients with long-term, surgically im-planted continuous-flow (CF) left ventricular (LV) assist devices (LVADs).

Recent guidelines endorse the important role of echocardiography in the clinical care of LVAD patients at several stages, including preoperative patient selection, perioperative imaging, postoperative surveillance, optimization of LVAD function, troubleshooting of LVAD alarms, and evaluation of native myocardial recovery.

2018年2月24日 · In LVAD-supported patients, surveillance echocardiography is performed at the pump’s baseline speed setting and includes LVAD-specific views and Doppler flow assessments , in addition to all the elements of a standard TTE exam for heart failure (HF) patients.

While many factors depend on successful implantation and outcome of left ventricular assist devices (LVAD), echocardiography remains an integral part and is vital to the success of this process. Transesophageal echocardiography (TEE) allows interrogation of all the cardiac structures and great vessels.

2010年10月1日 · The purpose of this review is to highlight the clinical role of echo and other noninvasive imaging modalities in the assessment of cardiac structure and function in patients with pulsatile and continuous flow LVADs. In addition, we discuss the role of imaging with emphasis on echo to detect LVAD dysfunction and device related complications.

Keywords: Echocardiography; comprehensive examination; left ventricular assist devices; mechanical circulatory support.

2012年5月10日 · Echocardiography is an important imaging modality used to determine the indication of left ventricular assist device (LVAD) implantation for patients with advanced heart failure (HF) and for serial follow-up to make management decisions in patient care post-implant.

Echocardiography is an indispensable tool in the evaluation, placement, management and follow-up of patients with left ventricular assist devices (LVAD). While transoesophageal echocardiography is the ideal tool in guiding the implantation procedure, transthoracic echocardiography is essential durin …

2021年4月21日 · Transthoracic echocardiography can be challenging in left ventricular assist device (LVAD) patients because of the implanted materials. The transhepatic window may represent a good alternative in selected LVAD patients with very difficult acoustic access in traditional transthoracic views.
