Share a memorable case from your EP lab and how it was addressed.
A man in his mid-40s with a history of hypertension, hyperlipidemia, and coronary artery disease presented with a complex case. Having undergone a 5-vessel coronary artery bypass grafting at age 34, he later experienced a cardiac arrest due to VT in 2018, which led to placement of a single-chamber ICD. Over the years, he experienced recurrent VT episodes, including symptomatic sustained VT and ICD shocks, initially managed with antitachycardia pacing therapy, but his condition continued to challenge standard treatments.

Seeking relief, the patient underwent endocardial VT ablation. While this procedure improved his condition, it did not fully resolve his symptoms. Working collaboratively, under the guidance of Dr Tolat, our EP team partnered with Dr Helaine Bertsch and the radiation oncology team to perform an additional endocardial ablation followed by stereotactic body radiation therapy. This groundbreaking approach allowed the patient to discontinue antiarrhythmic medications and achieve significant clinical improvement.

Thanks to this innovative collaboration between EP and radiation oncology, the patient’s quality of life has been dramatically enhanced. His case highlights the impact of multidisciplinary teamwork, advanced procedures, and a patient-centered approach in transforming outcomes for those with recurrent VT.

Describe your primary approach to LAAC.
Our LAA occlusion program performs procedures in collaboration with our colleagues in interventional cardiology, enhancing interdepartmental collaboration. Both the Watchman device (Boston Scientific) and the Amplatzer Amulet (Abbott) device are implanted. We are currently an enrolling center in the SIMPLAAFY trial evaluating various anticoagulation regimens post Watchman implant. Our program also works closely with our echocardiographer colleagues as we rely on their guidance for most cases. We have performed intracardiac echocardiography (ICE)-only Watchman implants. We have recently started performing concomitant procedures as well.

Does your program function as an AF Center of Excellence? How do you integrate team-based care pathways and lifestyle risk factor modification to improve outcomes? 
The core pillars of AF Centers of Excellence, as defined by the Heart Rhythm Society, are integral parts of our program. Over the past year, an express AF pathway was implemented to expedite patients from the emergency department to an electrophysiologist, improving access and equity of care. The electronic medical record (EMR) (Epic) was leveraged to flag stroke risk scores for patients with AF, ensuring timely initiation of guideline-directed anticoagulation therapy. Our program was also the first in the state to offer PFA using all commercially available catheters. 

Our dedicated lifestyle medicine program guides patients with AF toward better outcomes by promoting adherence to weight management, healthy living, and sleep apnea diagnosis and treatment. Data are actively collected to maintain transparency and evaluate patient outcomes.

What is your approach to lead extraction and management?
Dr Clancy, director of lead management, explains: “My approach to lead extraction begins with a comprehensive review of the patient’s history, device details, and imaging to assess lead complexity and potential risks. I work closely with a multidisciplinary team—including anesthesia, nursing, and cardiac surgery—to ensure full preparation, with surgical backup and all necessary extraction tools immediately available. During the procedure, I use a stepwise approach, beginning with simple traction and progressing to mechanical or laser sheaths as indicated, while continuously monitoring for complications. After the extraction, patients are observed for early complications, and the need for device reimplantation is evaluated. Throughout the process, standardized protocols and clear communication remain essential to ensuring patient safety and procedural success.”

The team also conducts biannual superior vena cava tear and lead extraction emergency drills to maintain readiness and confidence in responding to rare intraoperative complications. These exercises reinforce defined roles, communication, and rapid response, supporting the highest standards of safety in the OR.

Discuss your approach to treatment of AF in patients with heart failure (HF).
We take a comprehensive multispecialty approach to patients with AF and HF. This involves coordination with general cardiology and our advanced HF specialists when appropriate. Given the increasing data regarding the benefit of ablation in this population, as well as the increased safety and efficiency provided by pulsed field technology, we are moving towards ablation earlier in the course of managing this often-challenging population.

This culture of appreciation, connection, and collaboration supports excellence in patient care. 

Discuss your approach to arrhythmia management in athletes. 
When managing arrhythmias in athletes, the physician team begins with a comprehensive assessment that includes symptom review, family history, and diagnostic testing such as electrocardiography and Holter monitoring. Risk is then stratified to determine which athletes can safely continue training and which require intervention. Treatment is individualized; some athletes benefit from lifestyle modification and reassurance, whereas others may need pharmacologic therapy or ablation. Multidisciplinary collaboration is essential, and the team works closely with other specialties to ensure athletes recognize warning signs and understand the importance of adherence. Ongoing follow-up enables monitoring of progress and timely adjustment of care, with an emphasis on both safety and optimal performance.

How does your EP lab promote radiation safety and minimize fluoroscopy use during procedures?
Radiation safety is a top priority in our EP labs. All staff and physicians follow strict safety protocols, including the use of lead shielding, protective eyewear, and personal dosimeters to monitor exposure. The lab employs radiation-reducing technologies and positioning techniques to minimize scatter, and ongoing staff training reinforces adherence to best practices.

To further reduce radiation exposure, the team has adopted advanced 3D electroanatomic mapping systems and ICE, which enable complex procedures to be performed with little or no reliance on fluoroscopy. As a result, a substantial proportion of ablations—particularly for AF and SVT—are now completed with zero fluoroscopy. For cases requiring X-ray guidance, radiation exposure time and dose are tracked through the EMR system and quality dashboards. These data are reviewed regularly as part of continuous quality improvement to ensure safe, effective, and low-radiation procedural outcomes.

What are some of the dominant trends you see emerging in the practice of EP? 
We are seeing a significant rise in AF ablations, particularly with the adoption of PFA technology. Additionally, patients are increasingly using wearable devices to monitor and manage their arrhythmias. 

How do you use digital health and wearable technologies in your treatment strategies? 
We frequently recommend wearable technologies such as the Apple Watch and KardiaMobile (AliveCor) to help patients monitor their heart rhythm during and after treatment. Many patients now arrive having already purchased these devices and use them to document arrhythmias during symptomatic episodes. While it is still unclear whether these tools directly improve clinical outcomes, they do empower patients by giving them a greater sense of control over their health.

Is your EP lab involved in clinical research? 
Research is a cornerstone of the Heart & Vascular Institute at Hartford HealthCare, which is actively engaged in several ongoing clinical studies.

  1. Left vs Left: A randomized clinical trial comparing cardiac resynchronization therapy to left bundle branch area pacing.
  2. RADIATE-VT: A multicenter, randomized trial evaluating the safety and efficacy of cardiac radioablation vs repeat catheter ablation in patients with high-risk, refractory VT who have had VT recurrence after ablation and are candidates for additional intervention. 
  3. OMNY-AF: A prospective, single-arm study assessing the safety and efficacy of a novel catheter that combines a large ablation area with mapping capabilities. 
  4. Arm Aflutter Study: A randomized study evaluating the safety, feasibility, and efficacy of performing typical AFL ablation via the arm approach.
  5. SIMPLAAFY: A randomized trial comparing 2 monotherapy regimens with dual antiplatelet therapy after implantation of the Watchman FLX Pro device in patients with AF, assessing whether a less intensive drug regimen may reduce post-implant bleeding risk.
  6. AIM HIGHer: A multicenter, randomized, blinded, sham-controlled, investigational device exemption trial evaluating the safety and efficacy of cardiac contractility modulation therapy in patients with symptomatic HF with an ejection fraction of 40% to 70%. 

Does your institution offer EP-related procedures in an ambulatory surgical center (ASC)? 
Our institution does not currently offer EP-related procedures in an ASC; however, we may evaluate this model in the future as part of a long-term strategy to enhance patient access, efficiency, and overall care delivery.

Our team fosters close collaboration among staff and physicians, creating an environment of shared learning and mutual support. Clinical knowledge and skills are continually enhanced through vendor-led education, physician-led training, and self-directed study. In addition to professional development, team cohesion is strengthened through regular team-building activities—such as outings, potlucks, and recognition of life events—and through the acknowledgement of individual and group achievements. This culture of appreciation, connection, and collaboration supports excellence in patient care.
