Safety and Effectiveness of Left Bundle Branch Area Pacing Versus Conventional Cardiac Resynchronization Therapy in Heart Failure

This study will compare two different methods to pace the heart to treat heart failure including: 1. The current standard method of implanting a pacing lead in a vein on the surface of the left lower chamber of the heart (left ventricle) to deliver heart failure therapy. This method is called Cardiac Resynchronization Therapy (CRT). 2. The other method is using a lead implanted in the Left Bundle Branch Area (LBBA) of your heart. This method is called Left Bundle Branch Area Pacing or LBBAP. This lead is approved by the Food and Drug Administration (FDA) to be implanted in this area of the heart, but not to provide heart failure treatment.

BoStOn SCientific Rhythm MAnagemenT REgiStry (SOCRATES)

SOCRATES is part of Boston Scientific's (BSC) Post-market surveillance system. The implementation of such systems is mandatory per local regulations such as the Regulation '(EU) 2017/745 of the European Parliament and of the Council of 5 April 2017 on medical devices' or short Medical Device Regulation (MDR). The SOCRATES design is therefore based on the BSC's commitment as well as external regulatory requirements to proactively and systematically gather, record and analyze relevant data on the quality, performance and safety of devices throughout their entire lifetime.

A Post Approval Study to Evaluate Safety and Effectiveness of Multicompartmental Dosimetry Planning.

The purpose of this study is to assess the safety and effectiveness of treating a tumor using a different planning method called MCD for the FDA-Approved device, TheraSphere. TheraSphere Microspheres are microscopic radioactive glass spheres that deliver radiation therapy in the liver tissue where they are placed. This study investigates a procedure called multicompartment dosimetry (MCD). When using a multicompartment dosimetry approach, the doctor will look at images of the liver to see where there is tumor to determine where to treat. That area will be divided into "compartments" where the dose to tumor and the healthy liver are calculated separately. The goal of MCD is to give the tumor a higher radiation dose while protecting more of the healthy part of the liver. Traditional planning for the TheraSphere Microspheres procedure uses single compartment dosimetry (SCD) which treats the tumor and the healthy liver as one area so the dose is more evenly distributed and the dose to the tumor may be lower than with the MCD approach. The single compartment approach is standard and is well established however this research study is to see if giving TheraSphere Microspheres with an MCD planning method is safe and effective by evaluating the effect of radiation on the liver as well as how the tumor responds to higher doses
