Ischemic or Coronary Evaluations in Patients With Monomorphic Ventricular Tachycardia (VT) Electrical Storm Undergoing VT Ablation
Authors' conclusion
Ischemic evaluations in patients with monomorphic VT storm without ACS may not improve procedural outcomes or mortality after ablation.
Study context
- Population
- Patients with monomorphic VT electrical storm without acute coronary syndrome (ACS) undergoing VT ablation, Cleveland Clinic, 2014–202045% had ischemic evaluation
- Participants
- 97 patients
- Exposure
- Ischemic or coronary evaluation vs none before VT ablation
- Outcome
- Acute ablation outcomes and mortality during follow-up
Methodological detailssingle-centre, consecutive patients
- Single-centre
- Consecutive patients
Main finding
As reported in the abstract
Ischemic or coronary evaluation and ablation outcomes and mortality
- 45% underwent ischemic or coronary evaluation: coronary angiography (10%), noninvasive myocardial perfusion (26%), or both (9%)
- Low yield: no acute coronary occlusions identified
- No association between ischemic evaluation and acute ablation outcomes or mortality during follow-up
Observational data: associations, not effects.
Further findings
Yield of ischemic or coronary evaluations in monomorphic VT storm with known coronary disease (regardless of ablation status)
- Yield low
- Secondary analysis
