We report on three out of 270 consecutive patients (1.1%) suffering from coronary artery obstruction or occlusion at the end of transcatheter aortic valve implantation (TAVI). The partial or total obstruction of the coronary artery seen in the post-implantation aortography was accompanied by haemodynamic instability and electrocardiographic changes typical for myocardial ischaemia. Immediate pe...

Neuropeptide receptors were visualized in homografts of fetal cortex (E14) into adult rat cortex (immediate or 7 day delay) and spinal cord using in vitro autoradiographic techniques to explore the expression of peptide receptors in the same graft tissue in different central nervous system implantation sites. Receptors for bombesin (BN)-like peptides developed in the grafts by 3 weeks postimpla...

OBJECTIVES To evaluate a novel implant design for immediate implantation. This implant presents a specially designed expanded diameter midcrestal "wing" thread, which is aimed to provide added bone contact for greater insertion torque and primary stability. METHODS Mandibular premolars were extracted in 2 mongrel dogs, and immediate dental implants were inserted into the fresh extraction sock...

Vasodilatory shock frequently occurs after cardiac surgery, particularly after cardiac assist device implantation. This complication is often associated with high mortality, especially if refractory to conventional vasoconstrictor treatment. Methylene blue, a guanylate cyclase inhibitor, has been successfully used in the management of vasodilatory shock associated with cardiopulmonary bypass. W...

The present study aims to evaluate the influence of apicocoronal position and immediate and conventional loading in the percentage of bone-implant contact (BIC). Thus, 36 implants were inserted in the edentulous mandible from six dogs. Three implants were installed in each hemimandible, in different positions in relation to the ridge: Bone Level (at crestal bone level), Minus 1 (one millimeter ...

We describe the clinical course and postmortem pathological findings in a patient with essential tremor (ET) treated with deep brain stimulation (DBS) for 12 years. This 75 year old woman had a 13-year history of progressive ET prior to implantation of bilateral quadripolar DBS electrodes in the region of her ventral intermediate thalamic nuclei in 1996, producing immediate relief of arm tremor...

Angular and trans-zygomatic implantation is an alternative to most maxillary augmentations with severe deformations extreme atrophy. The usage of the frontal section maxilla for surgery after tooth extraction provides effective stability implants prostheses. This frequently used protocol intraoperative direct replacement traditional teeth. Immediate functional loading provisional restorations a...
