Read the original paper

In plain language

In 80 consecutive patients, complex left atrial and ventricular tachycardia ablations were completed with intracardiac ultrasound and 3D mapping, without fluoroscopy or lead protection, with no complications and, after an early learning curve, no longer procedures.

Summary based on
the abstract

What it found

  • All 80 complex ablation cases (70 left atrial arrhythmias, 10 ventricular tachycardia (VT)) were completed without fluoroscopy and without the need for rescue fluoroscopy.

    Key figures: 80 patients; 0 rescue fluoroscopy

  • After excluding the first 20 learning-curve cases, nonfluoroscopic ablation was not associated with an increase in mean procedural time (noninferior).

    Key figures: 229 ± 38 vs 225 ± 32 minutes; P = 0.002 for noninferiority

  • There was an initial increase in procedural time for left atrial arrhythmia ablation when transitioning to nonfluoroscopic ablation, indicating a learning curve.

  • Procedures used intracardiac echocardiography and 3D mapping without fluoroscopy or lead protection, and all were completed successfully with no complications.

Limits to keep in mind

A consecutive series of 80 patients without randomization, with the comparison group for procedural time not described in detail; staff dose and health outcomes were not measured, and center and operator experience are not reported.

How this summary was made

ORSIF prepared this summary with AI assistance from the abstract of the paper. A program then checked that the passage supporting each finding appears word for word in that source. A person has not yet reviewed each summary, so read the original before relying on a number. ORSIF summarizes research and does not endorse any product or company.
