Combined use of electro-anatomic mapping system and intracardiac echocardiography to achieve zero-fluoroscopy catheter ablation for treatment of paroxysmal atrial fibrillation: a single centre experience

AbstractFluoroscopy is the principal imaging method for catheter ablation (CA) of atrial fibrillation (AF). However, radiation exposure carries potential health risk to patients and operators alike. Our aim was to study safety and efficacy of zero-fluoroscopy CA of paroxysmal AF with a combined use of electroanatomic mapping system (EAM) and intracardiac echocardiography (ICE). In addition, impact of ICE/EAM automatic integration system and contact force (CF) sensing technology on procedural times were assessed. We included 144 consecutive patients (69% males, age 60  ± 10 years, BMI 29 ± 4,6) referred for CA of symptomatic paroxysmal AF. All procedures were performed only with EAM system and ICE. No fluoroscopy was used. The acute procedural success of complete pulmonary vein isolation was achieved in all patients (100%) and adverse events were detec ted in eight patients (5.6%). In 53 (37%) patients the use of ICE/EAM automatic integration system shortened procedural times compared to those performed without it (148 ± 35 vs. 187 ± 44 min, p

AliveCor is close to our hearts. Literally. David Albert, the co-founder of the company, started experimenting with handheld, wireless ECG devices in the late 90s. Approximately 10 years later we tried out their FDA-cleared, medical grade gadget. It was a truly inspiring moment. Needless to say, we’ve been keeping track of their journey ever since. In our eyes Kardia is the textbook example of technology shaping health care, empowering and supporting not only e-patients, but medical professionals as well. So, let’s take a look at their newest creation, the KardiaMobile6L! Why did the chicken cross the ro...

Conversely, the role of the absence of FVH (negative-FVH) remains unknown.MethodsConsecutive stroke patients were studied via magnetic resonance angiography, within 24 h of onset and major arterial occlusion. All patients were examined usi...

AbstractAim: to develop an algorithm for optimization of rate ‐adaptive pacing settings in heart failure patients with preserved ejection fraction (HFpEF) and permanent cardiac pacing.Methods: This is a prospective randomized controlled study. 54 patients with HFpEF, permanent atrial fibrillation (AF) and VVIR pacing were randomized to an intervention group with optimization of rate ‐adaptation parameters by using cardiopulmonary exercise testing (CPET) and pacemaker stress‐echocardiography (PASE) and to a control group with conventional programming. CPET, 6‐minute walk test (6‐mwt), echocardiography (echo), Duke...

In this study, we examined the safety of WATCHMAN implantation followed by 6 months of anti-thrombotic therapy in patients with a history of ICH.MethodsThis is a retrospective analysis of 63 patients with a history of ICH prior to WATCHMAN implantation (Group I) and 95 patients without a history of ICH who underwent WATCHMAN placement (Group II). The primary outcome was death, stroke, or major bleeding within 6  months of WATCHMAN placement.ResultsThe average CHA2DS2-VASc of Group I was 4.9  ± 1.7 vs 4.7 ± 1.4 for Group II (p = 0.34). The most common type of...

Authors: Atzema CL, Jackevicius CA, Chong A, Dorian P, Ivers NM, Parkash R, Austin PC Abstract BACKGROUND: Patients with atrial fibrillation frequently seek emergency care. Rates of guideline-concordant oral anticoagulant therapy for stroke prevention are suboptimal in the community. We assessed the association between prescribing of oral anticoagulants in the emergency department (relative to referral to a longitudinal care provider for treatment initiation) and long-term use of oral anticoagulants. METHODS: This retrospective cohort study performed at 15 hospitals in Ontario, Canada, involved patients aged 65...

Cardiology MCQ – Stroke risk in non valvar AF – Answer Stroke risk in chronic non valvar atrial fibrillation was increased by — fold in Framingham study: Correct answer: 2. Five fold In the same study, chronic AF with rheumatic heart disease had 17 fold increase in stroke risk. The study report had a follow up period of 24 years. Conventionally non valvar AF is defined as AF in the absence of moderate or severe mitral stenosis or prosthetic valve. Milder degrees of mitral stenosis and other valvular lesions are not excluded from ‘non-valvar’ AF! Back to question Reference Wolf PA, Dawber TR,...
