Balloon-expandable transcatheter aortic valve replacement outcomes by procedure location: Catheterization laboratory versus operating room

BACKGROUND

The impact of procedure location on clinical outcomes after TAVR remains unclear. We aimed to compare short-term outcomes in patients undergoing transcatheter aortic valve replacement (TAVR) in the catheterization laboratory (CATH) versus surgical operating room (OR).

METHODS

A retrospective review of 63,581 trans-femoral TAVR patients using balloon-expandable valves from 2015 to 2018 were captured utilizing the TVT Registry. Propensity score matching was performed using 24 covariates resulting in 2 risk-adjusted groups. Patients were further stratified by STS Risk Score with outcomes compared.

RESULTS

Propensity score matching resulted in 24,160 risk-matched CATH and OR patient pairs. Short-term clinical outcomes including all-cause mortality, stroke, major vascular complications, life-threatening bleeding, and new dialysis were similar between CATH and OR (p = all ns). There was no difference in conversion to open heart surgery between CATH and OR with both occurring at a very low rate (0.4% vs. 0.5%, p = 0.07). Moreover, the 30-day survival post-conversion was similar whether TAVR was performed in CATH versus OR (43.3% and 49.7%, p = 0.28). When stratified by STS Risk Score, there was no difference in conversion to surgery or 30-day mortality in low and intermediate risk patients between CATH and OR. For high risk patients, however, conversion to surgery was lower in CATH vs. OR (0.2% vs. 0.4%, p = 0.04) with no difference in 30-day survival (46% vs. 43%, p = 0.94).

CONCLUSIONS

Procedure location has minimal impact on TAVR procedural and 30-day outcomes with a very low conversion to open surgery rate between CATH versus OR for low, intermediate, and high-risk patients.

Off-site primary percutaneous coronary intervention in a new centre is safe: comparing clinical outcomes with a hospital with surgical backup

OBJECTIVES

To evaluate the procedural and clinical outcomes of a new primary percutaneous coronary intervention (PPCI) centre without surgical back-up (off-site PCI) and to investigate whether these results are comparable with a high volume on-site PCI centre in the Netherlands.

BACKGROUND

Controversy remains about the safety and efficacy of PPCI in off-site PCI centres.

METHODS

We retrospectively analysed clinical and procedural data as well as 6‑month follow-up of 226 patients diagnosed with ST-elevated myocardial infarction (STEMI) who underwent PPCI at VieCuri Medical Centre Venlo and 115 STEMI patients who underwent PPCI at Catharina Hospital Eindhoven.

RESULTS

PPCI patients in VieCuri Medical Centre had similar procedural and clinical outcomes to those in Catharina Hospital. Overall there were no significant differences. The occurrence of procedural complications was low in both groups (8.4 % VieCuri vs. 12.3 % Catharina Hospital). In the VieCuri group there was one procedural-related death. No patients in either group needed emergency surgery. At 30 days, 17 (7.9 %) patients in the VieCuri group and 9 (8.1 %) in the Catharina Hospital group had a major adverse cardiac event.

CONCLUSION

Performing PPCI in an off-site PCI centre is safe and effective. The study results show that the procedural and clinical outcomes of an off-site PPCI centre are comparable with an on-site high-volume PPCI centre.

The first year of the Venlo percutaneous coronary intervention program: procedural and 6-month clinical outcomes

Objectives

Analysis of the first results of off-site percutaneous coronary interventions (PCI) and fractional flow reserve (FFR) measurements at VieCuri Medical Centre for Northern Limburg in Venlo.

Background

Off-site PCI is accepted in the European and American Cardiac Guidelines as the need for PCI increases and it has been proven to be a safe treatment option for acute coronary syndrome.

Methods

Retrospective cohort study reporting characteristics, PCI and FFR specifications, complications and 6-month follow-up for all consecutive patients from the beginning of off-site PCI in Venlo until July 2012. If possible, the data were compared with those of Medical Centre Alkmaar, the first off-site PCI centre in the Netherlands.

Results

Of the 333 patients, 19 (5.7 %) had a procedural complication. At 6 months, a major adverse cardiovascular event (MACE) occurred in 43 (13.1 %) patients. There were no deaths or emergency surgery related to the PCI or FFR procedures. There was no significant difference in occurrence of a MACE or adverse cerebral event between the Alkmaar and Venlo population in the 30-day follow-up.

Conclusion

This study demonstrates off-site PCI at VieCuri Venlo to have a high success rate. Furthermore, there was a low complication rate, low MACE and no procedure-related mortality.
