3.6 Other complications
CAG examination in all patients showed no compression of the anterior
descending, posterior descending, and posterior left ventricular
arteries by the LBBAP electrodes. The contrast agent through the
arterial vessels did not penetrate the pacing electrode. There were no
complications, such as acute chest tightness, chest pain, angina
pectoris, acute myocardial infarction, cardiac tamponade, or broken
pacing electrodes during and within 24 h after surgery.
