Follow-up and endpoints
SE, TAVR, PPM, HAVB
ADVERSE EVENTS, SECONDARY, SECOND-DEGREE ATRIOVENTRICULAR BLOCK, MOBITZ
After TAVR, patients were rhythm-monitored for at least 24 h at an intermediate care unit continuously. Afterward, we referred the patients to the normal care unit for an additional 3 to 5 days. Before discharge, a 24-h Holter monitoring was performed in every patient. At least 30 days after TAVR, patients´ follow-up included assessment of adverse events, physical status, and 12-lead-ECG. The primary endpoint was defined as the occurrence of HAVB (i.e., second-degree atrioventricular block Mobitz type 2 or complete atrioventricular block) requiring PPM implantation within 30 days after TAVR. A new-onset persistent left BBB and HAVB were defined as an intraventricular conduction abnormality (ICA) and the occurrence of ICA within 30 days after TAVR as secondary endpoint. All endpoints were adjudicated by two independent investigators (SE, DM).
