Management of concomitant coronary artery disease and aortic valve stenosis in the era of transcatheter aortic valve treatment

Severe calcific aortic stenosis (AS) and coronary artery disease (CAD) have common risk factors and are frequently encountered in the same patient in clinical practice. CAD has been reported in ≥ 50% of AS patients undergoing both surgical treatment and transcatheter aortic valve implantation (TAVI). In the last two decades, TAVI has been established as a less invasive alternative to surgery. Recently, more and more young and low surgical risk patients undergo TAVI. Despite the high prevalence of CAD in patients treated with TAVI, the management strategy of concomitant CAD in these patients remains an area of considerable uncertainty. This review provides an updated overview of the current knowledge about this topic and offers points for reflection about the best approach to use.

Referring hospital involvement in early discharge post transcatheter aortic valve implantation: the TAVI (R-) EXPRES program

Aim: Over the past decade, transcatheter aortic valve implantation (TAVI) has matured into a valid treatment strategy for elderly patients with severe aortic stenosis. TAVI programs will grow with its adoption in low-risk patients. The aim of this study was to evaluate safety and feasibility of early discharge protocols, either home or back to a referring hospital. Methods: Consecutive patients undergoing TAVI between July 2017 and July 2019 were stratified into three discharge pathways from TAVI center: (1) early home (EXPRES); (2) early transfer to referring hospital (R-EXPRES); and (3) routine discharge (standard). Baseline, procedural, and 30-day outcomes were prospectively collected and compared per discharge pathway. Results: In total, 22 (5%) patients were enrolled in the EXPRES cohort [median age 78 (IQR: 73-81); mean Society of Thoracic Surgeons (STS) 2.4% ± 1.5%], 121 (29%) in the R-EXPRES cohort [median age 81 (IQR: 77-84); mean STS 4.3% ± 2.8%], and 269 (65%) in the routine discharge cohort [median age 80 (IQR: 75-85); mean STS 4.4% ± 3.1%]. EXPRES patients trended to be younger (P = 0.13) and had lower STS (P = 0.02). Early clinical outcome was similar through the different pathways including re-hospitalization rate. Median length of stay was one day longer for R-EXPRES vs. routine discharge patients [5 (IQR: 4-7) vs. 4 (IQR: 3-6); P < 0.01]. Median length of stay (LOS) was two days (IQR: 1-3 days) for EXPRES patients. Conclusion: Early discharge pathways home and to referral hospitals are safe and help streamline TAVI programs. LOS in referring hospitals may be further reduced.

Prevention and management of peri-procedural TAVR complications

Transcatheter aortic valve replacement (TAVR) is a safe and effective treatment strategy for severe aortic stenosis. However, peri-procedural complications can have a significant impact on acute and longer-term morbidity and mortality. Therefore, this review article provides a practical overview on how to prevent and manage the common and also rare but life-threatening peri-procedural TAVR complications.

TAVI specific sex consideration

The impact of sex on baseline characteristics and morphological and clinical presentation of degenerative aortic stenosis has been widely demonstrated but poorly understood. Moreover, differently from valve surgery, where patients were predominantly male, both sexes have been well represented in percutaneous treatment of aortic stenosis (AS), and women appeared to derive greater benefit with transfemoral aortic valve implantation (TAVI) compared to surgical treatment. This review focuses on sex-specific differences in epidemiology, pathophysiology, diagnostic issues, treatment options, and clinical outcomes of degenerative AS. Moreover, we evaluate how sex-based TAVI management, from device selection to procedural tricks, may affect outcomes.
