Article Synopsis
- A study evaluated the association of various cardiac sarcoidosis (CS) diagnostic criteria from different years (1993, 2006, 2014, and 2017) with negative health outcomes in patients.
- Research involved analyzing data from a global cardiac sarcoidosis registry and identified adverse events like mortality and surgeries in 587 patients.
- Results showed patients meeting the 1993 and 2006 criteria had significantly higher chances of experiencing adverse outcomes compared to those who didn't, while the 2014 and 2017 criteria did not show a significant correlation with these events.
Article Synopsis
- Ventricular tachycardia (VT) in cardiac sarcoidosis (CS) is linked to high mortality rates, and catheter ablation could offer better outcomes compared to traditional medical management.
- A study analyzed data from 158 patients with CS and VT at 16 medical centers over 16 years, focusing on the effectiveness of catheter ablation and accompanying medical treatments.
- Results showed that 54% of patients had complete success with ablation, with a significant reduction in VT storms and defibrillator shocks, although 46% experienced VT recurrence over a follow-up period of about 2.5 years.
Background: Lead damage is a complication caused by lead manipulation or heating damage from conventional electrocautery (EC) after cardiovascular implantable electronic device (CIED) replacement. Application of electrical plasma (PEAK PlasmaBlade) is a new technology that reportedly reduces this risk.
Objectives: This study was designed to compare the effect of EC versus PEAK PlasmaBlade on lead parameters and complications after generator replacement procedures.
Aims: Cardiac sarcoidosis (CS) is a known cause of ventricular tachycardia (VT). However, an arrhythmogenic presentation may not prompt immediate comprehensive evaluation. We aimed to assess the diagnostic and disease course of patients with arrhythmogenic cardiac sarcoidosis (ACS).

However, some patients may experience a worsened arrhythmia phenotype after ablation. We aimed to determine the prevalence and prognostic impact of arrhythmia exacerbation (AE) after post-infarction VT ablation.

- Ventricular arrhythmias are common cardiac conditions that can lead to serious health issues, including sudden death, and they range from occasional heart beats to life-threatening situations like ventricular tachycardia and fibrillation.
- Recent advancements in diagnosis and treatment of these arrhythmias, particularly through catheter ablation techniques, have significantly improved patient care.
- A new document has been created by global electrophysiology societies to replace older guidelines, summarizing updated practices and recommendations to help medical professionals effectively treat and manage patients with ventricular arrhythmias.*
Article Synopsis
- Ablation in the left ventricle carries a risk of blood clots, and this study focused on how to manage thromboembolism risk after ventricular tachycardia (VT) ablation in 217 patients.!
- Patients who had extensive ablation received a carefully managed dose of unfractionated heparin followed by 3 months of blood thinners, while those with less extensive ablation were treated with antiplatelet medications.!
- The study found that the thromboembolic and bleeding complications were low regardless of the treatment approach, suggesting the protocol for anticoagulation is effective and that antiplatelet therapy is a viable option for less extensive ablations.!
Association of preprocedural cardiac magnetic resonance imaging with outcomes of ventricular tachycardia ablation in patients with idiopathic dilated cardiomyopathy.

October 2017
Article Synopsis
- Preprocedural late gadolinium enhancement magnetic resonance imaging (LGE-MRI) may enhance the success of ventricular tachycardia (VT) ablation in patients with idiopathic dilated cardiomyopathy (DCM).
- A study comparing 96 patients found that those who had LGE-MRI demonstrated significantly higher procedural success rates (63% vs 24%) and better survival rates without VT recurrence, heart transplant, or death during follow-up.
- The findings suggest that using LGE-MRI prior to ablation can improve short-term outcomes, but the benefits in long-term outcomes need further exploration.
Article Synopsis
- Patients with a history of myocardial infarction who experience ventricular tachycardia (VT) recurrence after catheter ablation are at greater risk for death or heart transplantation, with risk varying based on the timing of the recurrence.* -
- In a study of 1412 patients, 42.8% had VT recurrence, usually within a few months after the procedure, and those who recurred within 30 days had a higher mortality risk compared to later recurrences.* -
- The risk of death or heart transplantation decreases over time post-ablation, with the greatest risk occurring soon after the recurrence and gradually lessening as time goes on.*
Article Synopsis
- Radiofrequency catheter ablation is a treatment for recurrent ventricular tachycardia (VT), and this study assessed its long-term safety and effectiveness using an open-irrigated catheter.
- Involving 249 patients with a mean age of 67.4 years, the study found a low adverse event rate (3.9%) and significant improvements in patient outcomes, such as a notable decrease in VT recurrence and fewer implantable cardioverter-defibrillator shocks post-treatment.
- Over three years, there was a steady reduction in amiodarone use and hospitalization, along with improved quality of life, suggesting that the procedure is effective for managing VT and enhancing patient well-being.
Background: A recent meta-analysis demonstrated a survival benefit in post-infarction patients whose ventricular tachycardia (VT) was rendered noninducible by catheter ablation. Furthermore, patients with noninducible VT had a lower VT recurrence rate than did patients whose VT remained inducible after ablation.
Objectives: The purpose of this multicenter cohort study was to assess whether noninducibility after VT ablation is independently associated with improved survival.
