The increased use of radiofrequency ablation (RFA) for atrial fibrillation (AF) has led to a rise in cases of pulmonary vein stenosis or occlusion (PVS/O) as a complication. Clinical signs of PVS/O post-ablation can vary from no symptoms to common respiratory issues like coughing, hemoptysis, shortness of breath, and chest pain.
Food and Drug Administration (FDA), has granted approval to Boston Scientific for its FARAPULSE Pulsed Field Ablation System. intermittent) atrial fibrillation (AF) and is a unique new alternative to standard-of-care thermal ablation treatment. said Nick Spadea-Anello, president, Electrophysiology, Boston Scientific. "The
Titled "Real-world Data Affirms Safety and Effectiveness of Low/Zero Fluoroscopy Atrial Fibrillation Ablation," the study was presented as a late-breaker at the 29th Annual International AF Symposium. Biosense Webster's zero fluoroscopy workflow is the first and only such workflow available in a radiofrequency (RF) cardiac ablation device.
A significant number of patients with mitral stenosis have septal hypertrophy making transcatheter mitral valve replacement difficult given the possibility of neo- left ventricular outflow tract obstruction.
In this week’s View, Dr. Eagle looks at the durability of pulmonary vein isolation using pulsed-field ablation, then examines genetic penetrance of dilated cardiomyopathy in genotype-positive relatives.
Mitral isthmus (MI) ablation is often challenging. It is not uncommon to encounter difficulties in creating a block line despite ablation from the left atrial side and epi-side (the coronary sinus, CS). In recent years, chemical ablation has been increasingly utilized for MI block.
Pulsed Field Ablation (PFA) has been demonstrated to promote fast and durable Pulmonary Vein Isolation (PVI) without the risk of PV stenosis or damage to adjacent structures. Atrial Fibrillation (AF) and Heart Failure (HF) are closely interlinked.
Pulsed field ablation (PFA) is a new treatment for atrial fibrillation (AF), and its selective ablation characteristics give it a significant advantage in treatment. In previous cellular and animal experiments, we have demonstrated that biphasic asymmetric pulses can be used to ablate myocardial tissue.
Radiofrequency ablation (RFA) of cavotricuspid isthmus (CTI)dependent atrial flutter requires ablation of the tricuspid annulus overlying the right coronary artery (RCA). Although it is considered safe, reports of acute and subacute RCA injury in human and animal studies raise the possibility of late RCA stenosis.
The unique mechanism of Pulsed Field Ablation (PFA) allows it to avoid esophageal damage, PV stenosis and permanent phrenic nerve paralysis. However, PFA has been noted to provoke coronary vasospasm when delivered in close proximity to the coronaries, often subclinical but at times leading to ventricular arrhythmias.
Pulsed Field Ablation is a relatively new modality for treatment of atrial fibrillation. In conventional ablation for atrial fibrillation, either heating of tissue is produced by radiofrequency application or freezing of tissues by cryoablation. Pulsed field ablation group had 305 patients while thermal ablation group had 302 patients.
JAMA Network Open) Medical therapy for aortic stenosis? (MedPage Today) -- Not all defibrillator pad positions may work equally well for patients with shockable out-of-hospital cardiac arrest. Early clinical data on evogliptin were disappointing.
Abstract Introduction Catheter-based radiofrequency (RF) ablation is generally regarded as the standard approach for patients with ventricular tachycardia (VT) refractory to antiarrhythmic drug therapy and may be considered as a first-line approach when there is a preference to avoid these agents.
The unique mechanism of Pulsed Field Ablation (PFA) allows it to avoid esophageal damage, PV stenosis and permanent phrenic nerve paralysis. It is unknown whether this propensity to develop hemolysis is unique to this catheter/waveform combination, or a more generalized property of PFA.
Regarding the issue at hand, it is widely known that in cases of mitral stenosis with AF, the left atrium (LA) is larger than the right atrium (RA) due to the obvious reason that the baseline LA was larger at the onset of AF. Pulmonary veins have been the primary target for ablation for many years, yet the success rates remain inconsistent.
Abstract Background The newly introduced nonthermal pulsed field ablation (PFA) is a promising technology to achieve fast pulmonary vein isolation (PVI) with high acute success rates and good safety features. One clinically nonsignificant PV stenosis occurred in the VHPSD group. Data comparing PFA to VHPSD-PVI is lacking.
BackgroundAortic stenosis (AS) in combination with left ventricular outflow tract obstruction (LVOTO) has occasionally been reported. Because the LVOTO might have been the cause of the hematuria, the patient underwent alcohol septal ablation, but this had little effect.
Method and Results A 54-year-old man with long history of atrial fibrillations developed PVS secondary to multiple radiofrequency ablation procedures. The stenosis was treated with a stent. Balloon angioplasty seems to be the widely preferred treatment of choice. He has since remained asymptomatic over 3 years of follow-up.
While , treating VTs with drugs is still a choice, permanent solutions by defining the VT circuit and ablating them, is the new norm. The following image and video clip is one such demonstration of ablating hidden diastolic paths between the entry and exit points. How can we remember this EP lesson easily ?
Results A 27-year-old male with dextrocardia with double outlet right ventricle, subaortic ventricular septal defect, and pulmonary stenosis status-post pulmonary valve replacement complicated by ventricular pacing dependence and subsequent atrial pacing dependence after atriotomy-based atypical flutter ablation developed recurrent mediastinitis and (..)

The LAD has moderate 40% ostial-proximal LAD stenosis and severe 90% mid LAD stenosis involving first diagonal branch. --The
During its Annual Conference, HRS 2024, the Heart Rhythm Society (HRS) announced findings from three new studies demonstrating the safety and efficacy of pulsed field ablation (PFA), a nonthermal ablation treatment for patients with atrial fibrillation (AF). See full findings from the FARADISE, admIRE Study, and Advent Trial here.
The VARIPULSE Platform is comprised of the VARIPULSE Catheter, a fully integrated variable-loop multielectrode catheter; the TRUPULSE Generator, a pulsed field ablation (PFA) generator; and the CARTO 3 System VARIPULSE Software, which provides full integration with the world's leading 3D cardiac mapping system.
BACKGROUND:Pulsed field ablation (PFA) is a promising treatment for atrial fibrillation. There were no incidences of adverse event fistula, diaphragmatic paralysis, MI, pericarditis, thromboembolism, PV stenosis, transient ischemic attack, or death. Circulation: Arrhythmia and Electrophysiology, Ahead of Print.
Research is also underway into algorithms for the diagnosis of Aortic Stenosis and Myocarditis and should be ready for commercialization in the next 18 – 36 months.
ABSTRACT Introduction The safety and efficacy of paroxysmal atrial fibrillation (PAF) ablation with the HELIOSTAR multielectrode radiofrequency (RF) balloon catheter have been demonstrated in European studies; data from elsewhere are lacking.

Angiography : LMCA — 90-99% osteal stenosis. LCx — 50-69% stenosis of the 1st marginal branch; with 100% distal LCx occlusion. Cath findings shown above in Dr. Nossen's discussion confirm multi-vessel disease , including 90-99% osteal stenosis of the LMCA. The image shows the impella device in place.
MANIFEST-17K provides confidence that, unlike conventional thermal ablation, PFA with the pentaspline catheter does not cause the most feared complication of AF ablation—esophageal damage—nor does it cause pulmonary vein stenosis or persistent injury to the diaphragm,” says senior author Vivek Reddy, MD , The Leona M.
Alcohol septal ablation (ASA) is indicated for drug-refractory hypertrophic obstructive cardiomyopathy (HOCM). Moreover, with an aging population, aortic valve stenosis (AS) is increasing, and surgical aortic valve replacement (SAVR) is indicated in these cases. However, it is not clear how the release of stenosis affects blood flow.
