Surgery for membranous subaortic stenosis. Long-term follow-up.
Hazekamp MG, Frank M, Hardjowijono R, Quaegebeur JM, Ottenkamp J, Huysmans HA
From 1958 to 1992, 105 patients were operated for discrete (or membranous) subaortic stenosis (DSAS). Our surgical techniques changed during this period. Before 1980 DSAS was removed by a sharp excision leaving the part on the mitral valve untouched (n = 58). After 1980 blunt dissection was used to enucleate DSAS completely (n = 47). The operation for DSAS was combined with aortic valve replacement (AVR) in 7 instances. Follow-up with recent echo-Doppler studies was complete in 100 patients. Rec...

Cerebral hemodynamics and oxygenation in preterm infants after low-vs. high-dose surfactant replacement therapy.
Dorrepaal CA, Benders MJ, Steendijk P, van de Bor M, van Bel F
In thirteen preterm infants receiving surfactant (Curosurf) replacement therapy, changes in cerebral hemodynamics and oxygenation were investigated by near infrared spectroscopy. Surfactant instillation led to an instantaneous increase in cerebral blood volume (CBV) in all infants, which was primarily due to an increase in deoxygenated hemoglobin. Five infants received a low dose (100 mg/kg = 1.25 ml/kg) of surfactant and 8 a high dose (200 mg/kg = 2.50 ml/kg). A significantly larger increase in...

The value of the stentless biovalve prosthesis. An experimental study.
Hazekamp MG, Goffin YA, Huysmans HA
Clinical use of the stentless bioprosthesis has not yet been accepted world-wide. Experimental studies are scarce. In a study in growing pigs, 23 aortic valve replacements were performed (7 stented bioprostheses (STB), 10 stentless bioprostheses (SLB) and 6 cryopreserved homografts (CAH)). Valves were studied macroscopically and microscopically after explantation. Five animals died between 1.5 and 4 months after implantation. Two STBs showed extreme calcific degeneration. A third STB animal died...

Histological organization of the right and left atrioventricular valves of the chicken heart and their relationship to the atrioventricular Purkinje ring and the middle bundle branch.
Lu Y, James TN, Bootsma M, Terasaki F
In the avian heart the right and left atrioventricular (AV) valves not only exhibit their own special anatomical characteristics, but they also are in close proximity to the conduction system. The right AV valve is a single, spiral plane of myocardium, in remarkable contrast to the fibrous structure characteristic of the mammalian tricuspid valve. A ring of Purkinje tissue encircles the avian right AV orifice and connects to the muscular valve. The chicken has no crista supraventricularis, its r...

Sequential analysis of infarcted and normal myocardium in piglets using in vivo gadolinium-enhanced MR images.
van Dijkman PR, Höld KM, van der Laarse A, Holman ER, Ozdemir HI, van der Nat TH, de Roos A, van der Wall EE
Gadolinium-enhanced magnetic resonance (MR) imaging was performed before, and 1 and 3 wk after coronary occlusion in domestic piglets. After administration of the contrast agent gadopentetate dimeglumine, two different enhancement patterns within the infarcted region were observed. The first pattern, showing peripheral enhancement of the infarcted region with absence of contrast in the center, was seen at 1 wk after occlusion at 5 min after administration of the contrast agent. The second patter...

[The value of cytological studies in nodular goiter: results in 495 patients].
Goslings BM, Smak Gregoor PJ, Samrén EB, Hamming JF, van Steenis GJ, Hermans J
The accuracy of clinical diagnosis and fine-needle aspiration biopsy (FNAB) was evaluated in a total of 495 patients of whom 183 were operated upon within 6 months after FNAB and 312 were not. Operated patients were divided into three subgroups with high, moderate or low suspicion of malignant neoplasms on clinical grounds. Histological examination revealed an overall malignant neoplasm rate of 23%. The rate, i.e. the positive predictive value, was 74% for the subgroup with high clinical suspici...

Increased urokinase receptor levels in human gastrointestinal neoplasia and related liver metastases.
Sier CF, Quax PH, Vloedgraven HJ, Verheijen JH, Griffioen G, Ganesh S, Lamers CB, Verspaget HW
Human carcinomas of the oesophagus, stomach, colorectum, and their liver metastases were previously shown to have increased levels of the urokinase-type plasminogen activator (u-PA). The proteolytic activity of u-PA on the surface of tumour cells is thought to play a key role in invasion and metastasis of malignancies. Therefore, in this study we quantitatively determined the presence of specific u-PA receptors in human gastrointestinal carcinomas, premalignant colonic adenomas, liver metastases...

Dipyridamole thallium-201 scintigraphy for improved detection of left anterior descending coronary artery stenosis in patients with left bundle branch block.
Jukema JW, van der Wall EE, van der Vis-Melsen MJ, Kruyswijk HH, Bruschke AV
In patients with left bundle branch block (LBBB) undergoing thallium-201 exercise scintigraphy septal perfusion defects are frequently observed irrespective of the presence or absence of coronary artery disease. Consequently, in these patients the specificity for detecting stenoses in the left anterior descending coronary artery (LAD) by thallium-201 scintigraphy is relatively low. It has been hypothesized that pharmacological vasodilation would result in higher specificity than conventional exe...

Potential of 99mTc-LDLs labeled by two different methods for scintigraphic detection of experimental atherosclerosis in rabbits.
Atsma DE, Feitsma RI, Camps J, van't Hooft FM, van der Wall EE, Nieuwenhuizen W, Pauwels EK
In this study we evaluated two different 99mTc-labeling techniques to produce 99mTc-low density lipoprotein (99mTc-LDL) suitable for the scintigraphic delineation of experimental atherosclerotic lesions. The two methods are 1) a procedure that uses stannous chloride and sodium borohydride (borohydride method) and 2) a procedure that uses sodium dithionite as a reducing agent and that has been successfully applied in previous scintigraphic atherosclerosis detection (dithionite method). 99mTc-LDL...

Structural proteins of equine arteritis virus.
de Vries AA, Chirnside ED, Horzinek MC, Rottier PJ
We have recently shown that the genome of equine arteritis virus (EAV) contains seven open reading frames (ORFs). We now present data on the structural proteins of EAV and the assignment of their respective genes. Virions are composed of a 14-kDa nucleocapsid protein (N) and three membrane proteins designated M, GS, and GL. M is an unglycosylated protein of 16 kDa, and GS and GL are N-glycosylated proteins of 25 and 30 to 42 kDa, respectively. The broad size distribution of GL results from heter...

Single and dual excitation of the conductance-volume catheter analysed in a spheroidal mathematical model of the canine left ventricle.
Steendijk P, van der Velde ET, Baan J
The conductance method employs a multi-electrode catheter to generate an electrical field and measure intracavitary segmental conductances. Left ventricular (LV) volumes are calculated using an algorithm which assumes the electrical field to be homogeneous. This assumption may be violated leading to a non-linear relation between conductance-derived and true volumes. In addition, this relation may vary between segments. A new method is introduced which uses a more homogeneous field. Volume estima...

Anisotropic conduction and reentry in perfused epicardium of rabbit left ventricle.
Schalij MJ, Lammers WJ, Rensma PL, Allessie MA
An experimental model of anisotropy was developed, consisting of a thin layer (1 mm) of perfused ventricular epicardium created by cryodestruction of the interventricular septum and the inner four-fifths of the free wall of the left ventricle. The electrophysiological properties of the 1-mm-thick surviving layer were the same as before freezing. Epicardial conduction was mapped with a 192-fold mapping electrode (spatial resolution 1 mm). In the intact ventricle transverse conduction was interrup...

Ventricular pressure-volume relations in vivo.
Baan J, van der Velde ET, Steendijk P
A number of fundamental mechanical properties of cardiac muscle as well as of the total ventricle are discussed. These include: Starling's law, shortening deactivation, homeometric autoregulation, and so-called hyperactivation associated with a small amount of ejection. Whenever appropriate, muscle properties are related to those of the intact ventricle. The phenomenon of load-dependence of the end-systolic pressure-volume relationship (ESPVR) receives particular attention and is placed wit...

Thrombogenicity and intimal hyperplasia after conventional and thermal balloon dilation in normal rabbit iliac arteries.
van Erven L, Velema E, Bos AN, Post MJ, Borst C
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...

Left ventricular segmental volume by conductance catheter and Cine-CT.
van der Velde ET, van Dijk AD, Steendijk P, Diethelm L, Chagas T, Lipton MJ, Glanz SA, Baan J
The ability of the conductance catheter method to measure left ventricular segmental and total volume was evaluated by comparison with the Cine-CT technique. In the seven dogs studied, 19 conductance catheter and simultaneous Cine-CT runs were obtained. High correlation coefficients were found for total volume and segmental volumes, except in the basal segment. However, in most cases there was a significant variability in slope and intercept between animals. Both methods are promising tools for...

[Obstructive uropathy after kidney transplantation. Experiences with endourologic incision of ureteral stenoses].
Schneider AW, Meyer-Moldenhauer WH, Conrad S, Otto U, Klosterhalfen H
Between 1985 und March 1991 we have managed 8 upper urinary tract obstructions in kidney transplants using an endourological approach. After a graft rejection was excluded an obstruction was initially diagnosed by nephrosonography and further confirmed by IVP or antegrade pyelography. To investigate the urodynamic relevance of the stenosis, all patients underwent preoperative diuretic isotope renography. In all cases a percutaneous pyelostomy was done to preserve renal function. 7 of these 8 pat...

The end-systolic pressure-volume relationship in young animals using the conductance technique.
Teitel DF, Klautz RJ, Cassidy SC, Steendijk P, van der Velde ET, van Bel F, Baan J
Evaluation of ventricular performance by the end-systolic pressure-volume relationship (ESPVR) has been extensively performed in the adult heart using the conductance technique. We undertook this study to validate the conductance technique and to generate ESPVRs in the small heart. To validate the technique, we simultaneously measured left ventricular volume by the conductance catheter and biplane cineangiography in nine piglets during changes in volume and contractility. Raw conductance volumes...
