Insights
This study highlights the successful simultaneous aortic valve replacement and pacemaker implantation in a patient with chronic renal failure. The procedure effectively treated severe aortic stenosis and complete heart block, improving patient outcomes.
Area of Science:
- Cardiology
- Cardiac Surgery
- Nephrology
Background:
- A 52-year-old male patient with chronic renal failure requiring hemodialysis presented with severe aortic valve stenosis and complete atrioventricular (A-V) block.
- Calcification of the aortic valve was extensive and suspected to have infiltrated the cardiac conduction system, causing the complete A-V block.
Abstract:
A 52-year-old man treated by hemodialysis under the diagnosis of chronic renal failure admitted to our hospital due to aortic valve stenosis and complete A-V block. Aortic valve was severely calcified, and the cause of complete A-V block was considered caused by the progressive calcification invasing to conduction system. The aortic valve replacement and pacemaker implantation using myocardial lead were simultaneously. Postoperative course was uneventful. The efficacy of simultaneous operation of aortic valve and pacemaker implantation was emphasized. However the generator implantation was recommended to perform in the several days after the operation because of destruction of the pacemaker function by counter shock for arrhythmia in the early post operative period.
