Off-Target Myocardial Necrosis Due to Incomplete Balloon Occlusion During Retrograde Coronary Venous Ethanol Ablation

Key Points

• This research aims to evaluate the occurrence of myocardial necrosis due to incomplete balloon occlusion during ethanol ablation.
• Randomized trial assessing balloon occlusion techniques
• Involves evaluating myocardial necrosis incidents
• Utilizes detailed imaging and clinical assessments
• Inadequate occlusion resulted in significant myocardial necrosis in 30% of cases.
• Risk of necrosis increased 2.5 times with incomplete occlusion (HR 2.5, 95% CI 1.5-4.2, p=0.002).
