Cardiac critical care after transcatheter aortic valve replacement

Safe implementation of enhanced recovery after surgery protocol in transfemoral transcatheter aortic valve replacement

Enhanced recovery after surgery (ERAS) protocols are gaining wide acceptance. We evaluated ERAS protocol implementation in transfemoral transcatheter aortic valve replacement (TAVR) patients. The ERAS protocol included (1) moderate sedation or general anesthesia with on-table extubation, (2) no pulmonary artery or urinary catheters, (3) arterial line removal within 4 hours, (4) no postoperative narcotics, (5) mobilization at 4 hours and ambulation within 8 hours, and (6) antihypertensive reinstitution without nodal blockers. Patients who received TAVR before and after ERAS implementation were compared (N = 121 and N = 368, respectively). The primary endpoint was total hospital length of stay (LOS). ERAS patients had a lower mean Society of Thoracic Surgeons predicted risk of mortality (6.7% vs 7.5%; P = 0.04). Unadjusted analysis demonstrated that ERAS was associated with significantly decreased mean LOS (2.8 vs 4.0 days, P <  0.001), decreased 30-day mortality (0.8% vs 5.0%; P = 0.003), and increased discharge home (90.2% vs 79.3%, P = 0.002) with no increase in 30-day readmission (11.1% vs 14.0%, P = 0.39). After risk adjustment, ERAS patients had a 1.87-day shorter LOS (P = 0.001) and trended toward increased discharge home (odds ratio 1.76, P = 0.078) without increased readmission (odds ratio 0.74, P = 0.4). An ERAS protocol for TAVR is safe and is associated with shorter LOS without increased readmission.

Intensive care unit management of transcatheter aortic valve recipients

Severe aortic stenosis is an increasingly prevalent disease that continues to be associated with significant mortality. Transcatheter aortic valve replacements have been used as an alternative to surgical aortic valve replacement in high-risk patients with multiple comorbidities. In this review, we discuss postoperative considerations pertinent to the successful management of these complicated patients in the intensive care unit.

Transcatheter aortic valve replacement: When invasive surgery is not an option

Aortic stenosis is a common problem that typically results from calcification and degenerative changes of the aortic valve that occur with advancing age. Because medical therapies have no clinically proven role, the management of severe aortic stenosis has primarily been surgical. For patients who are too high-risk for surgical aortic valve repair, transcatheter aortic valve repair (TAVR), approved by the FDA in 2011, may be an option. This article outlines what clinicians need to know about TAVR.
