Transseptal puncture without fluoroscopy using a radiofrequency needle: A case series.

Cardiol J 2020 Feb 10. Epub 2020 Feb 10.

Clinic for Electrophysiology, Herz- und Diabeteszentrum NRW, Ruhr-Universität Bochum, Bad Oeynhausen, Germany., Bad Oeynhausen, Germany.

Background: The non-fluoroscopy approach with the use of a three-dimensional (3D) navigation system is increasingly recognized as a future technology in the treatment of arrhythmias. However, there are a limited number of articles published concerning transseptal puncture without the use of fluoroscopy.

Methods: Presented in this paper is the first series of patients (n = 10) that have undergone transseptal puncture without the use of fluoroscopy under transesophageal echocardiography control using a radiofrequency transseptal needle and a 3D navigation system. Read More

Combined Surgical and Medical Therapy for Candida Prosthetic Endocarditis in a Patient with Repaired Tetralogy of Fallot.

Int Heart J 2018 Jul 6;59(4):877-880. Epub 2018 Jun 6.

Department of Cardiovascular Medicine, Graduate School of Medicine, The University of Tokyo.

Candida prosthetic endocarditis (CPE) is an uncommon and fatal complication in adults with congenital heart disease. The current guidelines for the management of fungal endocarditis recommend a combination of surgical and medical therapy. However, it still remains uncertain when surgical management in CPE patients should be performed. Read More

Five-year efficacy of pulmonary vein antrum isolation as a primary ablation strategy for atrial fibrillation: a single-centre cohort study.

Europace 2016 Sep 2;18(9):1335-42. Epub 2016 Feb 2.

Division of Heart and Lungs, Department of Cardiology, University Medical Center Utrecht, Heidelberglaan 100, 3584CX Utrecht, The Netherlands

Aims: Pulmonary vein antrum isolation (PVAI) is the cornerstone of atrial fibrillation (AF) ablation. There is an ongoing discussion on whether and when to add substrate modification to PVAI. This study evaluates (1) long-term efficacy of PVAI as a primary ablation strategy in all patients independently from AF type and (2) predictors of arrhythmia recurrence. Read More

Enhanced left ventricular training in corrected transposition of the great arteries by increasing the preload.

Eur J Cardiothorac Surg 2016 Jun 27;49(6):1571-6. Epub 2015 Nov 27.

Department of Cardiothoracic Surgery, German Pediatric Heart Center, Sankt Augustin, Germany.

Objectives: Patients with congenitally corrected transposition of the great arteries (ccTGA) without ventricular septal defect or left ventricular outflow tract obstruction need training of the morphological left ventricle (mLV) to undergo a double switch operation (DS) (atrial plus arterial switch). Establishing a sufficient gradient by pulmonary artery banding (PAB) is difficult and multiple re-pulmonary artery bandings (re-PABs) may be necessary to achieve the required physiology. We evaluate a new approach, consisting of a loose PAB in combination with an artificial atrial septal defect (aASD) to not only increase afterload but to dynamically enhance preload as well, in terms of the effectiveness of training of the mLV and the subsequent functional outcome after a DS.

Mechanical valve replacement in congenital heart defects in the era of international normalized ratio self-management.

ASAIO J 2005 Sep-Oct;51(5):530-2

Clinic for Thoracic and Cardiovascular Surgery Heart Center, North Rhine-Westphalia, Ruhr-University of Bochum, Bad Oeynhausen, Germany.

As the number of patients with congenital heart defects requiring heart valve replacement increases, the need for durable valve substitutes with good hemodynamic performance and a low incidence of complications becomes more apparent. The use of porcine xenografts is burdened with early fibrocalcific degeneration, whereas the use of mechanical heart valves led to an increased number of thromboembolic events, especially when implanted in the right side of the heart. We report on our experiences implanting bileaflet heart valves in congenital heart defects since the introduction of international normalized ratio (INR) self-management. Read More
