First case report in Japan of left ventricular pacing via a Coronary Vein in a patient with a mechanical tricuspid valve.
Circulation, 2008Co-Authors: Masataka Yoda, Toshiko Nakai, Kimie Okubo, Mitsumasa Hata, Akira Sezai, Atsushi Hirayama, Kazutomo MinamiAbstract:Transvenous endocardial pacemaker implantation is contraindicated in patients after prosthetic tricuspid valve replacement. A 65-year-old woman underwent both replacement of the mitral and tricuspid valves and pacemaker implantation with epicardial lead for bradycardia with chronic atrial fibrillation. At 2 years after this operation, the pacemaker's battery became low, and she was admitted for a battery exchange. To avoid frequent battery exchanges because of high stimulation thresholds, a left ventricular pacing lead was implanted via a Coronary Vein. There were no complications and the stimulation thresholds were stable. Coronary Vein leads enable a minimally invasive approach, improve safety, and give effective stimulation for patients with a prosthetic tricuspid valve. This is the first case report in Japan of left ventricular pacing in such a patient. (Circ J 2008; 72: 335 - 336)

Left Ventricular Pacing Through the Anterior Interventricular Vein in a Patient With Mechanical Tricuspid, Aortic and Mitral Valves
The Annals of Thoracic Surgery, 2005Co-Authors: Masataka Yoda, Bert Hansky, Sebastian Schulte-eistrup, Reiner Koerfer, Kazutomo MinamiAbstract:Transvenous endocardial pacemaker implantation is contraindicated in patients after mechanical tricuspid valve replacement. A 76-year-old woman who suffered from bradyarrhythmia was implanted with a left ventricular pacing lead through a transvenous Coronary Vein after aortic, mitral, and tricuspid valve replacements. There were no complications and the stimulation thresholds were stable. The use of Coronary Vein leads provides a minimally invasive approach, safety, and effective stimulation for patients with a mechanical tricuspid valve.

Coronary Vein balloon angioplasty forleft ventricular pacemaker lead implantation
Journal of the American College of Cardiology, 2002Co-Authors: Bert Hansky, Kazutomo Minami, Barbara Lamp, Dieter Horstkotte, Reiner Koerfer, Leon Krater, J.ürgen Vogt, Johannes HeintzeAbstract:OBJECTIVES Retrospective analysis of five cases of Coronary Vein balloon angioplasty performed to allow insertion of left ventricular pacing leads. BACKGROUND Coronary Vein stenoses or an insufficient vessel caliber can preclude transvenous placement of Coronary Vein leads. METHODS We compared our total patient population (n = 218), in whom we implanted Coronary Vein leads, to those five patients who required Coronary Vein angioplasty to allow lead placement. Standard over-the-wire Coronary artery balloon angioplasty catheters were used to dilate the vessel to 2.5 mm (n = 3) or 3.5 mm (n = 2). RESULTS Transvenous lead placement succeeds in >99% of patients. Four cases of target Vein stenoses and one case of a Vein of insufficient caliber were successfully treated by balloon angioplasty. There were no complications. CONCLUSIONS Coronary Vein angioplasty is an effective and safe technique to permit transvenous left ventricular pacing lead insertion in cases of target Vein stenoses or insufficient target Vein caliber.

Left heart pacing: Experience with several types of Coronary Vein leads
Journal of interventional cardiac electrophysiology : an international journal of arrhythmias and pacing, 2002Co-Authors: Bert Hansky, Juergen Vogt, Holger Gueldner, Johannes Heintze, Kazutomo Minami, Barbara Lamp, Dieter Horstkotte, Leon Krater, Gero Tenderich, Reiner KoerferAbstract:Our experience with 121 Coronary Vein (CV) leads in 116 patients shows that CV leads are the leads of choice for pacing the left ventricle (LV). The information gained from pre-operative venous angiography permits individual selection of the most appropriate lead model for each case. The use of steerable electrophysiology catheters facilitates guide catheter cannulation of the Coronary sinus (CS) when the anatomy is difficult and reduces the risk of complications. By selecting the CV lead model most suitable for each individual patient, we achieved successful implantation in 99.1% of patients. In this day and age, epicardial electrodes should be restricted to cases with CS anomalies which make CS cannulation impossible, and to LV lead implantation during heart surgery.

Stenting of Coronary Veins: a critical comment.
Europace : European pacing arrhythmias and cardiac electrophysiology : journal of the working groups on cardiac pacing arrhythmias and cardiac cellula, 2008Co-Authors: Bert HanskyAbstract:Daniel Gras was the first to describe Coronary venous stenting.1 Like other authors,2,3 he used a Coronary stent to fixate a Coronary Vein (CV) lead in a proximal Vein segment when more distal placement led to intractable phrenic nerve stimulation. At the Europace meeting in Lisboa in 2007 and at the 2008 Cardiostim conference in Nice, Szilagyi et al. presented their data on venous stenting in a larger cohort.

Left ventricular pacing and CRT. What CV lead fits into which Vein
Herzschrittmachertherapie Und Elektrophysiologie, 2006Co-Authors: Bert Hansky, Juergen Vogt, Holger Gueldner, Johannes Heintze, Barbara Lamp, Dieter Horstkotte, Reiner KoerferAbstract:: The experience of 579 patients with left ventricular pacing specific characteristics of various leads and lead types for left ventricular stimulation are reported. After describing the advantages of Coronary Vein (CV) leads versus epicardial lead usage for left ventricular stimulation, commercially available CV leads are introduced and discussed. Since there is no universally applicable CV lead, the individual optimal lead choice and the sequelae of erroneous lead choice are described in typical clinical examples.
