Summary
Acute ischemic stroke (AIS) is a rare complication during radiofrequency ablation for premature ventricular complexes (PVC). This case highlights AIS risk from excessive force during transaortic manipulation in PVC ablation procedures.
Area of Science:
- Cardiology
- Neurology
- Medical Device Technology
Background:
- Radiofrequency ablation is a common treatment for premature ventricular complexes (PVC).
- Acute ischemic stroke (AIS) is an infrequently reported complication during cardiac procedures.
- The specific mechanism of AIS during PVC ablation is not well-established.
Purpose of the Study:
- To report the first case of AIS occurring during catheter ablation for PVC.
- To elucidate the potential mechanism linking transaortic manipulation and AIS in this context.
- To raise awareness of AIS as a possible complication in PVC ablation.
Main Methods:
- A case report detailing a patient undergoing radiofrequency ablation for PVC.
- Description of the catheter manipulation technique, focusing on retrograde transaortic approach.
- Analysis of the procedural parameters, including contact force, leading to the AIS event.
Main Results:
- The patient developed AIS during the PVC ablation procedure.
- The event was associated with repeated retrograde transaortic manipulation.
- Excessive contact force during manipulation was identified as a potential contributing factor.
Conclusions:
- AIS can occur during catheter ablation of PVC.
- Repeated retrograde transaortic manipulation with excessive contact force may precipitate AIS.
- This case underscores the importance of careful technique and monitoring during PVC ablation to mitigate stroke risk.

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended.

01:15Ischemic Stroke l: Introduction
Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.
01:15Ischemic Stroke ll: Pathophysiology
An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
01:26Transient Ischemic Attack l: Introduction
A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...
