Catheter entrapment in a Björk-Shiley prosthesis in aortic position
Insights
Retrograde catheterization of the left ventricle across a Björk-Shiley prosthesis can lead to fatal complications. This procedure is no longer considered safe and should only be performed in exceptional cases by experienced cardiologists.
Area of Science:
- Cardiology
- Medical Malpractice
Background:
- Retrograde catheterization of the left ventricle is a medical procedure used for diagnostic and therapeutic purposes.
- The Björk-Shiley prosthesis is a type of mechanical heart valve used to replace damaged or diseased valves.
Observation:
- A case report details a lethal complication during retrograde catheterization of the left ventricle across a Björk-Shiley prosthesis.
- An 8F Sones catheter became irreversibly trapped after passing through the prosthesis's side orifice, impairing valve function.
- The patient experienced irreversible left heart failure and died before surgical intervention could be performed.
Findings:
- Passing a catheter across a tilting disc valve, such as the Björk-Shiley prosthesis, carries significant risks.
- The procedure can lead to impaired valve movement and catheter entrapment, potentially causing fatal outcomes.
Implications:
- Catheterization across tilting disc valves should only be undertaken under exceptional circumstances with strict indications.
- Experienced cardiologists must exercise extreme caution and take all necessary precautions when performing this high-risk procedure.
Abstract:
This report describes a lethal complication which occurred during retrograde catheterization of the left ventricle across a Björk-Shiley prosthesis. The authors were called upon to testify as experts in malpractice proceedings in this case. After an 8F Sones catheter had been passed through the small side orifice of the prosthesis and three ventriculograms had been carried out, it was apparent that the movement of the tilting disc valve was considerably impaired and that the catheter had become irreversibly trapped. As a consequence the patient died of irreversible left heart failure before an operation could be performed. Consequently passing a tilting disc valve can no longer be considered as completely safe. This procedure should only be used under exceptional circumstances requiring very strict indication. If such an intervention is necessary, then it should only be performed by experienced cardiologists, who should take all possible precautions to reduce risks.
