[CRT in atrial fibrillation--methodical and apparatus options in decision-making]

Area of Science:

• Cardiology
• Biomedical Engineering

Context:

• Heart failure (HF) and atrial fibrillation (AF) frequently coexist, particularly in severe HF.
• The efficacy of cardiac resynchronization therapy (CRT) in this patient group is debated and lacks clear guideline recommendations.
• Ventricular desynchronization is a key factor for CRT candidacy.

Purpose:

• To address the unresolved challenges of CRT in patients with coexisting heart failure and atrial fibrillation.
• To highlight the need for individualized methods and innovative device features for CRT optimization.
• To improve therapeutic outcomes in this complex patient population.

Summary:

• CRT optimization in heart failure with atrial fibrillation requires careful consideration of left ventricular lead placement.
• Postoperative device optimization is crucial for maximizing CRT benefits.
• Individualized approaches are encouraged due to the complexity of this comorbidity.

Impact:

• This work may lead to improved clinical decision-making for CRT in HF-AF patients.
• It encourages the development of novel technologies for better CRT performance.
• Ultimately aims to enhance treatment efficacy and patient quality of life.
