American journal of physiology. Heart and circulatory physiology, Volume 286, Issue 2, 9 2 2003, Pages H723-30 Quantification of left ventricular mechanical dyssynchrony by conductance catheter in heart failure patients. Steendijk P, Tulner SA, Schreuder JJ, Bax JJ, van Erven L, van der Wall EE, Dion RA, Schalij MJ, Baan J
Mechanical dyssynchrony is an important codeterminant of cardiac dysfunction in heart failure. Treatment, either medical, surgical, or by pacing, may improve cardiac function partly by improving mechanical synchrony. Consequently, the quantification of ventricular mechanical (dys)synchrony may have important diagnostic and prognostic value and may help to determine optimal therapy. Therefore, we introduced new indexes to quantify temporal and spatial aspects of mechanical dyssynchrony derived fr... Abstract

European journal of heart failure, Volume 5, Issue 3, 1 1 2003, Pages 315-317 Eligibility for biventricular pacing in patients with an implantable cardioverter defibrillator. Molhoek SG, Bax JJ, van Erven L, Steendijk P, van der Wall EE, Schalij MJ
Implantable cardioverter defibrillator (ICD)-therapy prevents sudden death in patients at high risk, but incidence of death due to heart failure remains unaltered. Recent data suggest that biventricular (BV) pacing is useful in patients with heart failure. It is unclear, how many patients with an ICD indication may have an indication for BV pacing. Therefore all patients who received an ICD were analyzed for eligibility of BV pacing using the following criteria: NYHA class III or IV, QRS duratio... Abstract

Borger van der Burg AE, Bax JJ, Boersma E, Bootsma M, van Erven L, van der Wall EE, Schalij MJ
Survivors of cardiac arrest due to ventricular arrhythmias are at risk for recurrent events. The role of revascularization in secondary prevention for survivors of cardiac arrest has been addressed in various studies with conflicting results. A total of 142 survivors of cardiac arrest with coronary artery disease were evaluated according to a standardized protocol, including 2-dimensional echocardiography, myocardial perfusion scintigraphy, coronary angiography, and electrophysiologic testing. R... Abstract

Biventricular pacing has been introduced to treat patients with end-stage heart failure, and short-term results of this technique are promising. Because data on longer follow-up are limited to 3-month follow-up, the sustained effect of biventricular pacing is unclear and long-term survival is unknown. Forty patients with end-stage heart failure in New York Heart Association (NYHA) functional class III or IV with left ventricular (LV) ejection fraction (EF) 120 ms, and left bundle branch block mo...

Introduction: Radiofrequency ablation (RFCA) of ventricular tachycardia (VT) is a potential curative treatment modality. We evaluated the results of RFCA in patients with VT. Methods and results: One hundred fifty-one consecutive patients (122 men and 29 women; age 57 +/- 16 years) with drug-refractory VT were treated. Underlying heart disease was ischemic heart disease in 89 (59%), arrhythmogenic right ventricular cardiomyopathy (ARVC) in 32 (21%), and idiopathic VT in 30 (20%; left ventricle i... Abstract

Angioplasty inflicts damage to the arterial wall. We studied whether augmented medial smooth muscle cell necrosis leads to augmented intimal hyperplasia and thus aggravates restenosis. Sixty-three normal femoral arteries of New Zealand White rabbits were overstretched with an angioplasty balloon during either maximal vasoconstriction with phenylephrine (32 arteries) or maximal vasodilation with nitroprusside (31 arteries). After 3 days' survival, medial necrosis was determined as percentage... Abstract

Acute occlusion and restenosis are the major complications of percutaneous transluminal coronary balloon angioplasty. Application of heat during balloon dilation was postulated to reduce these complications. We evaluated thrombogenicity and intimal hyperplasia of normal rabbit iliac arteries after conventional (37 degrees C) and thermal balloon dilation. Thermal dilation was performed with a radio-frequency-heated balloon, provided with three thermocouples attached to the inside of the balloon s... Abstract

Mechanical origin of "acoustic" wall damage and its effect on wall healing. van Erven L, van Leeuwen TG, Post MJ, van der Veen MJ, Velema E, Borst C
Pulsed mid-infrared lasers are an alternative to excimer lasers for transluminal angioplasty. The mid-infrared lasers, however, were reported to produce "acoustic" wall damage that might impair the immediate and long-term results. To study the immediate and long-term effects on the arterial wall, 184 craters (1 mm diameter and 1 mm depth) were produced perpendicular to the intimal lining in the thoracic aortas of pigs. Three types of craters were evaluated: Ho-YSGG laser-induced (lambd... Abstract

To study adjacent tissue damage after delivery of holmium, thulium and excimer laser pulses, porcine thoracic aortas were irradiated in vivo. After 3 days, microscopic analysis of 67 craters produced by all three lasers demonstrated large dissections extending from the craters. The mean diameter of the dissections was smaller for excimer-induced craters (1.38 +/- 0.42 mm; n = 22) than for holmium-induced (2.7 +/- 0.87 mm; n = 22) and thulium-induced (2.37 +/- 0.42 mm; n = 14) craters (p less tha...

Lasers in surgery and medicine, Volume 10, Issue 4, 1 1 1990, Pages 363-374 Early and late arterial healing response to catheter-induced laser, thermal, and mechanical wall damage in the rabbit. Oomen A, van Erven L, Vandenbroucke WV, Verdaasdonk RM, Slager CJ, Thomsen SL, Borst C
Pulsed lasers are being promoted for laser angioplasty because of their capacity to ablate obstructions without producing adjacent thermal tissue injury. The implicit assumption that thermal injury to the artery is to be avoided was tested. Thermal lesions were produced in the iliac arteries and aorta of normal rabbits by a) electrical spark erosion, b) the metal laser probe, and c) continuous wave neodymium-yttrium aluminum garnet (Nd-YAG) laser energy through the sapphire contact probe. High-e... Abstract

In 48 patients with severe claudication due to a total obstruction of the femoropopliteal artery, percutaneous recanalization was attempted with a 2.2 mm diameter rounded sapphire contact probe in conjunction with a continuous wave Nd:YAG laser. In eight patients the contact probe laser catheter took a subintimal course that could not be redressed. Laser recanalization needs high-resolution diagnostic information on the complex anatomy of the obstruction. Intra-arterial ultrasound imaging may pr... Abstract
