Safety and efficacy outcomes of left atrial posterior wall isolation compared to pulmonary vein isolation and pulmonary vein isolation with linear ablation for the treatment of persistent atrial fibrillation.
Pulmonary wall isolation (PWI) is increasingly used as an adjunctive lesion set to compliment pulmonary vein isolation (PVI), especially in patients with persistent atrial fibrillation (AF). The objective was to compare outcomes of catheter ablation in patients with persistent AF undergoing PVI with and without adjunctive PWI.
Radiofrequency current (RFC) catheter ablation for patients with paroxysmal atrial fibrillation (AF) has been shown to be safe and effective in first-line therapy. Recent data demonstrates that RFC ablation provides better clinical outcomes compared to antiarrhythmic drug (AAD) in the treatment of early AF disease. Furthermore, studies comparing RFC and cryoballoon have established comparable efficacy and safety of pulmonary vein isolation (PVI) for patients with symptomatic paroxysmal AF.
Atrial fibrillation (AF) is a growing healthcare burden, for which pulmonary vein isolation (PVI) using cryoballoon (CB) or radiofrequency (RF) represent attractive therapies. Women are at higher risk of recurrence after AF ablation and present a specific complications profile. Therefore, a systematic catheter-specific assessment of pulmonary vein isolation is urgently needed in women.
Second-generation cryoballoons (2-CBs) are widely used in atrial fibrillation (AF) ablation, however, the optimal freeze dose is still under debate. Recently, the time-to-isolation (TTI), which is the time until an acute pulmonary vein isolation (PVI), is noted based on clinical and experimental studies, and a TTI-guided strategy has been proposed. However, in real-world human CB procedures, the direct association between the TTI and PVI durability has not been well examined. We sought to investigate whethe...
Pulmonary vein antrum isolation by radiofrequency ablation has become a preferred treatment for atrial fibrillation. The aim of our research is to study the anatomy of the PVantrum and its related structures with special emphasis on the esophageal relation to the various components of the antrum, as thermal injury is a common complication.
Ablation index (AI) is useful to complete circumferential pulmonary vein isolation (CPVI) for atrial fibrillation (AF), but the role of radiofrequency power in AI-guided CPVI remains to be elucidated.
The significance of inducibility of atrial fibrillation (AF) after pulmonary vein isolation (PVI) in patients with AF remains disputable and polarizing. Therefore, we investigated the prognostic value of inducibility of AF on long-term outcome after PVI in patients without low-voltage left atrial (LA) substrate.
Cryoballoon pulmonary vein isolation (cPVI) in patients with atrial fibrillation requires fluoroscopic guidance, causing a relevant amount of radiation exposure. Strategies to reduce radiation exposure in electrophysiologic procedures and specifically cPVI are of great importance. The aim of this study was to evaluate a possible reduction of radiation dose using the novel Azurion 7 F12 x-ray system compared with its predecessor Allura FD10.
To investigate whether the increased obstruction of the pulmonary arteries was associated with reduced pulmonary vein areas in acute pulmonary embolism (APE).
Despite technological advancements, radiofrequency catheter ablation for pulmonary vein isolation remains a challenging procedure, as maneuvering the catheter to obtain effective lesions is technically complex and time consuming. For this reason, balloon-based ablation systems have been developed, which can quickly and easily isolate the pulmonary veins (single-shot), with outcomes comparable with point-by-point catheter ablation in the paroxysmal atrial fibrillation population. In this review, we discuss 3...
Little data exists on the electrophysiological differences between sustained (sAF, >5min) versus self-terminating non-sustained AF (nsAF,
Presence of arrhythmogenic left atrial (LA) low-voltage substrate (LVS) is associated with reduced arthythmia freedom rates following pulmonary vein isolation (PVI) in persistent atrial fibrillation (AF). We hypothesized that LA-LVS modifies amplified sinus-P-wave (APW) characteristics, enabling identification of patients at risk for arrhythmia recurrences following PVI.
Pulmonary vein isolation (PVI) using ablation index (AI) incorporates stability, contact force (CF), time, and power. The CLOSE protocol combines AI and ≤6 mm interlesion distance. Safety concerns are raised about surround flow ablation catheters (STSF). To compare safety and effectiveness of an atrial fibrillation (AF) ablation strategy using AI vs. CLOSE protocol using STSF.
Scimitar syndrome consists of anomalous pulmonary vein drainage to the inferior vena cava. Its name derives from the image this anomalous pulmonary vein creates on a chest radiograph. We describe a case of normal venous pulmonary vein drainage that also presented the scimitar sign due to an aorto-collateral vessel.
Novel videoendoscopy demonstrating irregularly pulsatile GI bleeding from left atrium via an esophageal fistula after pulmonary vein isolation and catheter ablation for atrial fibrillation (with video).
There is still sparse information regarding phrenic nerve palsy (PNP) during the cryoablation of both right-sided pulmonary vein (PV) and its anatomical predictors.
Pulmonary vein isolation (PVI) with cryoballoon ablation (CBA) is routinely guided by fluoroscopy and utilizes contrast injection to ensure catheter positioning and pulmonary vein occlusion. Non-fluoroscopic imaging techniques including electromagnetic mapping (EM) and intracardiac echocardiography (ICE) have demonstrated reduced fluoroscopy times and contrast exposure. Utilization of color flow Doppler to evaluate vein occlusion with the balloon has not been evaluated as an alternative to contrast injectio...
To examine the rate of delayed or no isolation of hospitalized patients with pulmonary tuberculosis (TB) and the causes for isolation failure.
A wireless pulmonary artery pressure sensor (CardioMEMS) is approved for implantation via the femoral vein. The internal jugular vein (IJ) is an attractive alternative access route commonly used in pulmonary artery catheterization.
Puerperal ovarian vein thrombophlebitis is a rare pathology. We present the case of a 23-year-old female who presented with fever and cough that occurred after vaginal delivery and persisted after several courses of antibiotics between the 2nd and 20th day postpartum. CT pulmonary angiography revealed right subsegmental pulmonary embolism. An abdominal ultrasonographic examination led to the diagnosis of ovarian vein thrombosis. She was treated with warfarin for 2 weeks with a good response. Our case high...
Precise lung isolation technique with visual confirmation is essential for thoracic surgeries to create a safe and clear surgical field. However, in certain situations, such as when patients have massive pulmonary secretion or when the fiberoptic bronchoscopy (FOB) is not applicable, lung isolation has been performed blindly.
The role of the Na current in the automaticity of the pulmonary vein myocardium was examined in isolated guinea pig pulmonary vein cardiomyocytes and tissue preparations. Tetrodotoxin inhibited the automaticity of pulmonary vein tissue preparations by suppressing the diastolic depolarization of the action potential. ATX-II, which increased the density of persistent component of the Na current (late I), induced a depolarization of the resting membrane potential followed by spontaneous firing of action potent...
We have read with great interest the article of Johner and colleagues, which for the first time correlates the pattern of the electrical activity of the coronary sinus (CS) with the propensity to induce sustained atrial fibrillation (AF) after pulmonary vein (PV) isolation. We believe that this study is at the crossroad of two paramount topics which have driven our AF ablation strategy so far: defining the electrical signature and detailing the anatomical framework of AF perpetuation. This article is protec...
The use of an intraprocedural observation and pharmacologic challenges have been proposed as a means to differentiate permanent pulmonary vein (PV)-left atrial conduction block from inadequate ablation lesions.
Pulmonary vein stenosis is a well-known complication after radiofrequency catheter ablation of atrial fibrillation. Although surgical repair is indicated for younger patients and patients with multiple stenoses, the appropriate procedure for acquired pulmonary vein stenosis has not been established. In this study, we report the successful outcome of our modified sutureless technique using a left atrial appendage flap for left-sided pulmonary vein stenosis after radiofrequency catheter ablation.
