Clinical Effect of Adaptive Servo-Ventilation on Left Atrial Pressure During Catheter Ablation in Sedated Patients With Atrial Fibrillation.

Circ J 2021 Apr 13. Epub 2021 Apr 13.

Department of Cardiology, Tokyo Medical and Dental University.

Background: Sedation during pulmonary vein isolation (PVI) for atrial fibrillation often provokes a decline in left atrial (LA) pressure (LAP) under atmospheric pressure and increases the risk of systemic air embolisms. This study aimed to investigate the efficacy of adaptive servo-ventilation (ASV) on the LAP in sedated patients.Methods and Results:Fifty-one consecutive patients undergoing cryoballoon PVI were enrolled.

Pseudothrombotic appearance on pulmonary valve by intracardiac echocardiography during atrial fibrillation ablation.

J Arrhythm 2021 Apr 23;37(2):448-449. Epub 2020 Nov 23.

Division of Cardiology Internal Medicine Ⅲ Hamamatsu University School of Medicine Hamamatsu Japan.

We report a case with a thrombus-like image on pulmonary valve detected by intracardiac echocardiography before transseptal puncture for atrial fibrillation (AF) ablation. The multimodality assessment provided diagnosis of the imaging artifact and exclusion from the harmful mass. This finding could be useful for a safety management of AF ablation and avoidance of an unnecessary interruption of the procedure. Read More

Transseptal puncture: procedural guidance, challenging situations and complications management.

EuroIntervention 2021 Mar 30. Epub 2021 Mar 30.

University Hospital, Zurich, Switzerland.

A number of interventional procedures based on the transseptal puncture (TSP) have been developed over the last years. The increasing number of interventional procedures, as well as the use of large-bore sheaths and complex devices, has led to improvements in technique and equipment. The combined use of fluoroscopy and of trans-esophageal echocardiography (TEE) has increased safety and precision. Read More

Effectiveness and safety of single transseptal ablation for atrial fibrillation in real-word practice.

Clin Cardiol 2021 Apr 22;44(4):547-554. Epub 2021 Feb 22.

Department of Cardiology, Yonsei University Health System, Seoul, Republic of Korea.

Background: We have previously reported that unilateral groin-single transseptal (ST) ablation in patients with paroxysmal atrial fibrillation (AF) was safe and significantly reduced patient discomfort compared with bilateral groin-double transseptal (DT) ablation.

Hypothesis: In the present study, we hypothesized that ST ablation would be as effective and safe as DT ablation in real-world practice like previous study. Among the 1765 consecutive patients in the Yonsei AF ablation cohort from October 2015 to January 2020, 1144 patients who underwent radiofrequency ablation were included for the analysis. Read More

VersaCross radiofrequency system reduces time to left atrial access versus conventional mechanical needle.

J Interv Card Electrophysiol 2021 Jan 22. Epub 2021 Jan 22.

Division of Cardiology, Vancouver General Hospital, University of British Columbia, 2775 Laurel Street, Level 9, Vancouver, BC, V5Z1M9, Canada.

Background: Despite maturing experience, transseptal puncture (TSP) remains a challenging part of percutaneous left atrial appendage closure (LAAC) and has inherent risks and safety concerns in accessing the left atrium (LA). The VersaCross radiofrequency (RF) system (Baylis Medical), a new RF-tipped pigtail wire-based TSP system, may facilitate LA access by serving as an exchange support wire once access is achieved.

Methods: We retrospectively compared TSP safety and procedural efficiency in 10 consecutive LAAC cases using the VersaCross RF system to 10 cases using the conventional BRK1-XS mechanical needle (Abbott Vascular). Read More

A new transseptal solution for enabling left atrial access of large delivery sheaths.

J Cardiovasc Electrophysiol 2021 Mar 2;32(3):729-734. Epub 2021 Feb 2.

Division of Cardiology, Vancouver General Hospital, University of British Columbia, Vancouver, British Columbia, Canada.

Multimodality imaging anatomy of interatrial septum and mitral annulus.

Heart 2020 Dec 22. Epub 2020 Dec 22.

National Heart and Lung Institute, London, UK.

The detailed anatomy of the interatrial septum (IAS) and mitral annulus (MA) as observed on cardiac magnetic resonance, computed tomography and two-dimensional/three-dimensional transthoracic and transesophageal echocardiography is reviewed. The IAS comprises of two components: the septum primum that is membrane-like forming the floor of the fossa ovalis (FO) and the septum secundum that is a muscular rim that surrounds the FO. The latter is an enfolding of atrial wall forming an interatrial groove. Read More

Case report: Buddy wire technique to facilitate atrial septal crossing during transcatheter transseptal mitral valve implantation.

Eur Heart J Case Rep 2020 Dec 9;4(6):1-4. Epub 2020 Nov 9.

Division of Cardiology, Rush University Medical Center, 1717 W Congress parkway, Suite 313, 3-Kellogg, Chicago, IL, USA.

Background: Transcatheter mitral valve-in-valve implantation (MVIV) has emerged as a viable treatment option in patients at high risk for surgery. Occasionally, despite appropriate puncture location and adequate dilation, difficulty is encountered in advancing the transcatheter heart valve across interatrial septum.

Case Summary: We describe a case of a 79-year-old woman with severe chronic obstructive pulmonary disease (COPD), prior surgical bioprosthetic aortic and mitral valve replacement implanted in 2007, atrial fibrillation, and Group II pulmonary hypertension who presented with progressively worsening heart failure symptoms secondary to severe bioprosthetic mitral valve stenosis and moderate-severe mitral regurgitation.

Iatrogenic Atrial Septal Defect After Percutaneous Mitral Valve Repair With MitraClip: Should We Consider Closing Them Routinely?

J Invasive Cardiol 2020 Nov;32(11):E295-E297

La Paz University Hospital, Paseo de la Castellana, 261, 28046 Madrid, Spain.

Percutaneous MitraClip intervention for treatment of severe mitral regurgitation in high surgical risk patients requires large-diameter transseptal sheaths that can result in iatrogenic atrial septal defect (iASD), and its prevalence is higher compared with non-MitraClip procedures. This iASD is not routinely closed because the possible consequences are still not fully understood. However, we believe it is important to identify patients who may benefit from its closure immediately after the procedure to prevent hemodynamic deterioration and long-term negative clinical outcomes.
