BACKGROUND Long-term follow-up after stent dilation of native and acquired pulmonary artery stenosis is scarce in the pediatric population. Most cohorts include a myriad of anatomies and associated conditions. METHOD In order to establish objective performance criteria, we performed a retrospective review of all patients who underwent unilateral pulmonary artery stenting in biventricular phys...
We carried out an analysis of our initial experience with using an Amplatz device for percutaneous closure of ventricular septal defects in 15 patients. The patient's ages ranged in from 1 to 44 years. Seven were infants with heart failure. In 4 patients, the ventricular septal defect was located in the muscular portion of the ventricular septum; in 11 patients, it was in the perimembraneous po...
Physical disfigurement and functional impairments associated with facial trauma are a challenge to a prosthodontist, because even novel sophisticated surgical reconstructive techniques fail to provide adequate support for dental resection prosthesis. Therefore, different endosseous implants are often used as prosthesis-supporting elements. Manufacturers of dental implants have recently presente...
A 1 60-YEAR-OLD man with a history of recent heart failure caused by both primitive and ischemic dilated cardiomypathy underwent the successful implantation of a left ventriclar assist device (Novacor LVAS; WorldHeart, Ottawa, ON, anada) under cardiopulmonary bypass. Intraoperative transsophageal echocardiography (TEE) performed immediately fter implantation showed the correct placement of both...
BACKGROUND The majority of prosthetic heart valves currently implanted are tissue valves that can be expected to degenerate with time and eventually fail. Repeat cardiac surgery to replace these valves is associated with significant morbidity and mortality. Transcatheter heart valve implantation within a failed bioprosthesis, a "valve-in-valve" procedure, may offer a less invasive alternative. ...
BACKGROUNDS Deep brain stimulation is widely used for the treatment of movement disorders such as Parkinson's disease and dystonia. After the implantation of electrodes an immediate improvement of clinical symptoms has been described. It is unclear, whether movement kinematics are also changed by this 'microlesion effect'. METHODS To gain further insight into these mechanisms, we studied arm,...
A 78-year-old male patient underwent implantation of cardiac resynchronization devise with defibrillator (CRT-D) for dilated cardiomyopathy and congestive cardiac failure. Patient received a Guidant CRT-ICD. RV lead during implantation, subclavian access was obtained by venogram assisted extra thoracic puncture of the subclavian vein. Right atrial (RA) lead was initially attempted in the right ...
OBJECTIVES We propose a modified simultaneous kissing stenting technique (MSKS) based on systematic implantation of a protective stent in the proximal main vessel (PMV) proximally to the bifurcation before simultaneous kissing stenting (SKS). BACKGROUND SKS has been proposed in large-size coronary vessel bifurcation lesions (BLs) when the PMV can accommodate two stents. SKS implies, however, ...
In vivo tissue engineering uses the body as a bioreactor for tissue regeneration, thus placing stringent requirements on tissue scaffolds, which should be mechanically robust for immediate implantation without a long in vitro cell culture time. In addition to mechanical strength, vascular grafts fabricated for in vivo tissue engineering approach must have matching mechanical properties to the t...
INTRODUCTION The treatment of calcified coronary artery lesions is a challenge for percutaneous angioplasty. Rotational atherectomy is an established technique for the effective modification of these lesions prior to conventional angioplasty and stent implantation. Drug-eluting stents (DES) have shown encouraging results in complex lesions and high-risk patients. METHODS This retrospective st...
