Case Report: Endovascular therapy for an iatrogenic vertebrojugular arteriovenous fistula and pseudoaneurysm induced by multiple vascular procedures

The patient, who complained of dizziness, was initially diagnosed with bradycardia and aortic paravalvular leak. However, the symptoms persisted even after permanent pacemaker implantation and transcatheter closure of the aortic paravalvular leak.

Bradycardia-dependent block is characterized by slowed or blocked conduction through His-Purkinje (HPS) fibers. We describe a case of bradycardia-dependent block after transcatheter aortic valve replacement (TAVR). We describe a case of bradycardia-dependent block after transcatheter aortic valve replacement (TAVR).

Left bundle branch block (LBBB) is a frequent complication of transcatheter aortic valve implantation (TAVI) and was shown to predict advanced atrio-ventricular block and pacemaker implantation (PI).1,2 1,2 Previous studies focused on persistent TAVI-induced LBBB. There are limited data on TAVI-related intermittent LBBB.

EMS reports intermittent sinus tachycardia and bradycardia secondary to some type of heart block during transport. Limiting one's interpretation to marked bradycardia with high-grade AV block in need of pacing in this patient with multiple syncopal epiosodes — more than suffices for "the quick answer".

Atrial fibrillation is also a predictor of worse outcomes in this case (Alborzi). Sinus Tachycardia ( common in any trauma patient. ).

Post PCI an intra-aortic balloon pump (IABP) was placed and a combination of norepinephrine and dobutamine was needed to maintain perfusion pressures. As per Dr. Nossen — today's initial ECG ( LEFT tracing in Figure-2 ) shows sinus bradycardia with QRS widening due to bifascicular block ( RBBB/LAHB ).

His first electrocardiogram ( ECG) is given below: --Sinus bradycardia. As his pain was very severe, emergency physicians concerned of aortic dissection and ordered a thoracic CT scan. Blood pressure: 130/80 mmHg, heart rate: 45/min, respiratory rate: 18/min, SaO2: %98, body temperature: normal.

There was concern for aortic dissection, so a CT was done and was negative. This is sinus bradycardia. Another ECG was recorded at 35 minutes: It is hard to discern a difference At this point, the first troponin I returned at 0.55 ng/mL (significantly elevated) A D dimer was also elevated. The QRS is narrow.

Sinus bradycardia, normal conduction, normal axis, normal R wave progression, no hypertrophy. Cardiology noted there was no STEMI criteria and the first troponin was in the normal range (25ng/L, with normal <26), so alternate diagnoses were considered and the patient was sent for CT to rule out aortic dissection.
