Performing cardiac catheterization in patients with right ventricular outflow tract obstruction requires careful pressure tracing. Catheter manipulation can cause severe dynamic obstruction, leading to life-threatening hypotension.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Pediatric Cardiology

Background:

  • Accurate hemodynamic assessment is crucial for managing right ventricular outflow tract (RVOT) obstruction during cardiac catheterization.
  • Withdrawal pressure tracings help delineate the location and severity of RVOT obstruction.

Observation:

  • Catheter manipulation within the RVOT, whether for gradient measurement or angiographic positioning, can induce dynamic RVOT obstruction.
  • This induced obstruction can lead to a complete halt in forward blood flow.

Findings:

  • Dynamic RVOT obstruction is a rare but critical complication during cardiac catheterization in affected patients.
  • The phenomenon can result in severe, life-threatening hypotension.

Implications:

  • Clinicians must maintain vigilance for this potential complication during cardiac catheterization procedures.
  • Awareness of this hemodynamic trace is essential for patient safety and effective management of RVOT obstruction.
