Ventricular tachycardia associated with removal of a Swan-Ganz catheter
Insights
Swan-Ganz catheter removal can trigger dangerous ventricular tachycardia, even without prior arrhythmias. Continuous monitoring and experienced staff are crucial during removal to prevent cardiac events.
Area of Science:
- Cardiology
- Critical Care Medicine
Background:
- Swan-Ganz catheterization is a common procedure for hemodynamic monitoring in critically ill patients, particularly those with myocardial infarction.
- Persistent unexplained tachycardia is a challenging clinical presentation requiring careful diagnostic evaluation.
Observation:
- A patient with myocardial infarction experienced persistent tachycardia, necessitating Swan-Ganz catheterization.
- Ventricular tachycardia developed during the removal of the Swan-Ganz catheter, despite no preceding arrhythmias.
- Direct-current cardioversion was required to restore normal sinus rhythm.
Findings:
- Swan-Ganz catheter removal can precipitate serious ventricular arrhythmias, such as ventricular tachycardia.
- The absence of prior ventricular ectopy does not preclude the risk of arrhythmia during catheter withdrawal.
Implications:
- Continuous vigilance and uninterrupted monitoring are essential throughout the entire duration of Swan-Ganz catheter use, from insertion to removal.
- Experienced personnel, ECG monitoring, and immediate availability of resuscitation equipment (lidocaine, defibrillator) are recommended for safe catheter removal.
Abstract:
Swan-Ganz catheterization was performed because of persistent unexplained tachycardia in a patient with myocardial infarction. Although there was no premonitory arrhythmia, ventricular tachycardia developed as the catheter was removed. Direct-current cardioversion was required. The occurrence of ventricular tachycardia requiring cardioversion in a patient who experienced no ventricular ectopy earlier in his hospitalization shows that Swan-Ganz catheter removal may provoke potentially serious arrhythmia. Uninterrupted vigilance from the time the Swan-Ganz catheter is inserted to the time it is removed is essential. Therefore, we recommend that the catheter be removed under ECG monitoring by experienced personnel, with lidocaine and a defibrillator available.
