Description of intervention(s) / exposure
This is a pilot study on the safety and effectiveness of the 3PM ES360 introducer sheath. The 3PM ES360 is an expandable introducer sheath set, comprising of an expandable introducer sheath and compatible dilator. It is intended for use in transcatheter aortic valve replacement (TAVR) procedures. The procedure will be performed by experienced cardiologists on participants who are already scheduled to undergo a TAVR procedure. The procedure should take around one hour. This type of procedure requires a sheath so there would not be any added time for using this sheath, however the procedure may take an additional 10 minutes to collect study data. Participants will be followed up for 30 days post procedure at which point they will be exited from the study.
The study will be monitored by an independent Contract Research Organisation (CRO) who will review all relevant medical notes. The sponsor and CRO will train the study team on the study and the device.

Outcomes
Primary outcome [1] 333968 0
To establish safety and effectiveness of the ES360 sheath in TAVR procedures, as measured by incidences of major vascular complication, and/or major bleeding events according to Valve Academic Research Consortium (VARC3) criteria. Adverse events will be assessed via clinical examination. The study team do not anticipate any adverse events in addition to the standard of care adverse events that may be experienced. Standard risks to a TAVR procedure that you should discuss with your doctor if you have not already include bleeding, blood vessel complications, problems with the replacement valve, stroke, heart rhythm problems, kidney disease, heart attack, infection and death.

Statistical methods / analysis
Due to the low number of study participants only limited, descriptive data analysis will be possible. A detailed Statistical Analysis Plan (SAP) will be prepared prior to performing any final analysis. The plan will define populations for analysis, outline all data handling conventions and specify all statistical methods to be used analysis of the data. The SAP may include modifications of the overview of statistical analysis described in the protocol. Data generated during this study may be useful to inform sample size selection for future studies.
