EuroPCR highlights (18-20 May) Part 2: Optimising the TAVI procedure
This year, the annual meeting of EuroPCR was held as a 3-day digital event, supplemented with on-demand content. EuroPCR historically covers a diverse range of topics in interventional cardiovascular medicine.
There were many sessions dedicated to the evolving changes of transcatheter aortic valve implantation (TAVI). This second part of the report details conference highlights on optimising the TAVI procedure with a focus on pathway optimisation, early discharge, and the importance of the TAVI coordinator.

Objectives of TAVI optimisation
Dr Derk Frank, Dr Francesco Saia, and Dr Sandra Lauck outlined why optimising the TAVI procedure is needed, including new challenges presented with COVID-19, increased TAVI workload with an all-risk indication, and untreated patients. As the world emerges from the pandemic, optimising resources and increasing hospital capacity will become the biggest challenges according to Dr Francesco Saia. While Dr Sandra Lauck believes that the goals in contemporary TAVI should include a predictable patient trajectory of care, excellent patient outcomes and efficient and scalable processes of care.

TAVI pathway optimisation
|Since the first TAVI procedure in 2002,1 it has been simplified, and contemporary TAVI is based on a minimalist pathway with maximum safety, leading to improved patient outcomes.2-4|
With TAVI expanding into the low-risk patient cohort, the population available to undergo TAVI is growing. For many organisations, this will require optimisation of the procedure pathway to accommodate the increasing number needed to be treated. There is a need to streamline patient management to treat more patients without compromising patient safety.
In Dr Francesco Saia’s experience, protocols help to prepare the patient before they arrive at the hospital. These protocols allow for safe transfer to the ward and a continuity of care. The use of protocols allows for standardisation and there exists protocols for every step along the patient’s trajectory of care: from entry to discharge. Deviation from the pathway should be limited and discussed with the heart team.
Minimalist TAVI is maximal planningFrancesco Saia
Improving conduction abnormalities with optimal valve implantation depth
Exploring how conduction abnormalities post-TAVI can lead to increased length of stay, Jonathan Mailey presented study results that looked at optimal implantation depth. Implantation depth is a modifiable predictor of permanent pacemaker implantation, and a high implantation depth can reduce the impact on the conducting system; by changing implantation technique, conduction abnormalities could be reduced. 279 patients who underwent TAVI with a SAPIEN 3 valve were retrospectively reviewed and a 52% relative risk reduction in pacemaker implantation at 30-days was found when implantation depth was high vs low. Similarly, a 66% relative risk reduction in left bundle branch block was found in high vs low valve deployment. A higher implantation depth did not have adverse effects on patient outcomes with no change in death, stroke, embolisation or emergency SAVR. These results suggest that implantation depth is important and focusing on a high valve deployment could reduce the need for a pacemaker implantation, improving patient outcomes.
Dr Sandra Lauck, Dr Francesco Saia and Dr Olivier Darremont discussed how early discharge contributes to optimisation of the TAVI procedure, conserving resources and delivering improved patient outcomes. With an expected backlog of care and delays to treatment as the pandemic abates, reducing the length of stay is mandatory to increase capacity and allow the possibility of treating more patients. Fast-track 24h protocols make use of risk criteria for early discharge to limit unexpected complications. Early mobilisation post-procedure contributes to early discharge, and the MobiTAVI5 trial has demonstrated the feasibility, safety and efficacy of early discharge, with early mobilisation, conferring additional organisational and patient benefits.
Dr Marco Angelillis, et al. presented a poster on the predictors of early discharge in TAVI. Patients were categorised as either fast track (<3 days) or slow track (>3 days) based on length of stay. Patients whose length of stay was >3 days were analysed for possible predictors of increased length of stay, including procedural complications or clinical and electrographic characteristics. New onset or worsening of conduction disturbances and major or life-threatening bleeding were independently associated with increased length of stay (>3 days). Therefore, it was concluded that only patients with bleeding complications or major conduction disturbance should be monitored >48h. Early discharge of <3 days did not adversely affect 30-day safety patient outcomes.
With TAVI moving into the low-risk patient indications, empirical evidence shows 80% of patients early discharged (<3 days) to home, and that early discharge is both feasible and safe across all-risk patients; however, the goal should not be day-1 discharge but rather early discharge based on patient status, according to Prof. Helene Eltchaninoff.
Role of the TAVI coordinator
The TAVI coordinator has been described as the cornerstone for a successful TAVI program. Sandra Lauck explained how the TAVI program coordinator is responsible for coordination with all relevant parties to achieve improved patient outcomes. Derk Frank expanded that this provides a seamless continuation of care. The program coordinator is pivotal in ensuring that healthcare professionals along the patient’s trajectory are aligned on the objectives of care.
The pivotal responsibilities of a TAVI coordinator include leading the program, facilitating patient-focused processes and improving communication. Dr Derk Frank emphasised the importance of the TAVI coordinator by highlighting how the immediate impact can be measured when their TAVI coordinator is on annual leave: in these instances, the mean length of stay increases by 1 day. He described that it is ideal to have 1 coordinator per 100 TAVI procedures performed/year.
Role of the TAVI coordinator has become an essential indicator of TAVI programs across multiple regionsSandra Lauck
As the world emerges from the pandemic into a ‘new normal’, there will be an expectation of improved organisational efficiencies to get through a backlog of care: TAVI is a procedure that is minimally invasive and whose pathway has been optimised and streamlined to deliver excellent patient outcomes and confer organisational benefits.

Highlights from EuroPCR 2021 focus on TAVI for aortic stenosis: presentations include TAVI in a before-now excluded patient population, bicuspid aortic stenosis and on the contemporary challenges for TAVI such as expanding patient populations, valve durability and long-term outcome data in TAVI patients. Furthermore, as the world emerges from the pandemic into a ‘new normal’, there will be an expectation of improved organisational efficiencies to get through a backlog of care: read how TAVI is a procedure for the post-pandemic era, since it is minimally invasive, the pathway has been optimised and streamlined to deliver excellent patient outcomes and confer organisational benefits.
