Abstract excerpt

Hereditary transthyretin (TTR) cardiac amyloidosis is a rare infiltrative cardiomyopathy. Involvement of the cardiac conduction system may lead to atrioventricular block. Left bundle branch area pacing (LBBAP) represents an emerging pacing strategy. We report a case of hereditary TTR amyloidosis with 2:1 atrioventricular block (second-degree), a wide QRS escape rhythm, and reduced ejection fraction, in which...
