While medical management is often the first-line treatment of heart failure, mechanical circulatory support and ventricular assist device therapies are being increasingly employed to improve symptoms and end-organ dysfunction from heart failure. Patients with left ventricular assist devices (LVADs) are not only surviving with their disease, but also thriving as a result of LVAD support, and many return to normal activities of daily life. Thus, these patients present to hospitals for noncardiac surgeries, both elective and urgent, with increasing frequency. This chapter explores some commonly used ventricular assist devices, the altered physiology that accompanies LVAD therapy with continuous flow devices, as well as some of the anesthetic considerations that are vital for patients presenting for both elective and urgent surgeries.","PeriodicalId":103017,"journal":{"name":"Cardiac Anesthesia: A Problem-Based Learning Approach","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122967079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Modern electrophysiology (EP) procedures, including placement of permanent pacemakers and implantable cardioverter-defibrillators and catheter ablation of cardiac arrhythmias, have been shown to reduce mortality and improve quality of life and symptoms. These procedures can also reduce the need for antiarrhythmic medications and hence reduce side effects related to these medicines. The procedures performed in the EP laboratory can be protracted and painful and therefore frequently require the assistance of an anesthesia team for patient comfort.

From an anesthesiologist’s perspective, these cases are unique as they require both a detailed understanding of complex patient physiology and the need to be planned as fast-track procedures. Echocardiography is the cornerstone to success for these procedures, and typically a separate team of echocardiographers may be involved in the conduct of the case.

Anesthesiologists must be familiar with different methods of lung isolation, including management of episodes of hypoxemia, hypercarbia, and sequelae of increased pulmonary vascular resistance during lung isolation. Procedures with arrested heart on cardiopulmonary bypass require expertise in insertion of a percutaneous coronary sinus catheter for administration of retrograde cardioplegia, in addition to insertion of a pulmonary artery vent for left ventricular decompression.

From the preoperative assessment to postoperative care, the main goal is to expedite recovery while minimizing the inherent risks associated with cardiac surgery.

The goal of the postoperative care phase is focused on reducing or completely bypassing the intensive care unit and ultimately decreasing hospital length of stay. Yet, here is where FTCC seems unable to achieve its goals due to multifactorial barriers. An integral part of successful FTCC is constant reevaluation of the patient through each of the perioperative phases (pre-, intra-, and postoperatively).","PeriodicalId":103017,"journal":{"name":"Cardiac Anesthesia: A Problem-Based Learning Approach","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130224294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
