Introduction:
In 2020, the sutureless Perceval PLUS aortic valve was introduced, featuring a new anticalcification treatment (FREE) and a shorter inflow ring in the XL size. We aimed to evaluate its early outcomes compared to earlier Perceval S design.
Methods:
We retrospectively analyzed 1136 patients who received the Perceval bioprosthesis between 2007 and 2022, including 222 implanted with the Perceval PLUS. Patients implanted with the Perceval S were divided into two groups (S-OLD and S-NEW) depending on the sizing strategy. Survival, hemodynamic performance, and pacemaker implantation rates were assessed.
Results:
The cohort had a mean age of 77 years and a EuroSCORE II of 6.3%. The observed 30-day mortality was similar across groups (3.7%, p = .326). Perceval PLUS demonstrated significantly improved hemodynamics, with lower peak (20.44 ± 8.95 mmHg) and mean gradients (11.44 ± 5.12 mmHg) compared to the S design (p < .001). A permanent pacemaker implantation (PPI) rate of 5.3% was achieved in minimally invasive aortic valve replacement in the PLUS group.
Conclusion:
Early results from the Perceval PLUS show a secure profile with maintained benefits from the Perceval platform. The Perceval PLUS shows improved hemodynamics in comparison with the Perceval S and achieves low PPI rate.

01:24Testing a Claim about Population Proportion
There are two methods of testing a claim about a population proportion: (1) Using the sample proportion from the data where a binomial distribution is approximated to the normal distribution and (2) Using the binomial probabilities calculated from the data.
The first method uses normal distribution as an approximation to the binomial distribution. The requirements are as follows: sample size is large...
01:11Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
