Complete atrioventricular block induced during left heart catheterization.

چکیده
Complete atrioventricular block (CAVB) during cardiac catheterization is a rare complication. We describe a patient with preexisting complete right bundle branch block who developed CAVB during left-sided cardiac catheterization. CAVB was induced when a left-sided catheter was passed through the aortic valve. We speculate that the patient's His bundle was injured by mechanical compression. Physicians should always pay attention to the possibility of the development of CAVB during cardiac catheterization, particularly in patients with preexisting heart block.

results Between March 2009 and February 2012, 47 patients were included in the analysis. Thirty patients (63%) had acute disorders of the conduction system: 19 patients presented isolated complete left bundle branch block (LBBB), 9 patients isolated complete atrioventricular block (CAVB), and 2 patients both conduction disorders, with a total of 21 LBBBs and 11 CAVBs. A definite pacemaker was i...

Catheter induced cardiac arrhythmia is a well-known complication encountered during pulmonary artery or cardiac catheterization. Injury to the cardiac conducting system often involves the right bundle branch which in a patient with preexisting left bundle branch block can lead to fatal arrhythmia including asystole. Such a complication during central venous cannulation is rare as it usually doe...
متن کاملSlow ventricular tachycardia presenting with acute liver failure
OBJECTIVES Cardiac hepatopathy is an important differential diagnosis of acute liver failure. Slow ventricular tachycardia (slow VT) is a ventricular tachycardia (VT), in which heart rate is below the typical frequency of VT. We here report a case of acute liver failure in a patient with slow VT. METHODS The 64-year old male patient with history of cardiac pacemaker implantation for complete ...

A68-year-old woman with exertional chest discomfort was referred for cardiac catheterization. Her medications did not include atrioventricular (AV) nodal blocking agents, and she had no prior history of dizziness or syncope. Her admission ECG was normal, including a normal axis, PR interval, and QRS morphology and duration (Figure 1). Right heart catheterization and coronary angiography demonst...
