Sinus of Valsalva aneurysms are unusual, particularly when located on the left coronary sinus. They are mainly asymptomatic, however once ruptured, they are associated with high mortality. We present hereinafter an atypical case of a 71-year-old patient with an unruptured left sinus of Valsalva aneurysm causing myocardial ischaemia due to a compressed left main coronary artery. Surgical endoaneurysmorrhaphy was performed; however, a dehiscence of the suture line between the patch and the aortic wall required additional percutaneous implantation of a vascular occluder...

REVIEW
Leah J Hauser, Justin H Turner, Rakesh K Chandra
Stenting has long been used in the paranasal sinuses with the goals of maintaining a patent sinus cavity during the postoperative healing process and preventing restenosis from inflammation or scarring. More recently, drug-eluting stents have been introduced. Steroid-impregnated dressings and implants appear to be safe, although likely have increased systemic absorption compared with topical nasal steroid sprays and rinses. There is evidence to support the use of steroid-releasing implants in the ethmoid cavity in the postoperative period; however, more study is needed to truly define the role of these implants...

INTRODUCTION: We have recently used highly pure β-TCP (beta-tricalcium phosphate) as the bone grafting material to avoid highly invasive autogenous bone grafting. We evaluated the osseoconduction potential of highly pure β-TCP in sinus augmentation surgery treatment. MATERIALS AND METHODS: The study group comprised 13 patients who underwent maxillary sinus floor augmentation with β-TCP alone. Seven patients underwent sinus augmentation and implant placement simultaneously...

The posterior maxillary segment frequently exhibits insufficient bone mass to support dental implants. Sinus floor augmentation enables implant placement in the posterior maxilla. This case series included ten sites, in which sinus floor elevation was done using sinus lift balloon system followed by augmentation utilizing irradiated cancellous bone allograft. Postoperative radiographic assessment of vertical bone gain was done at 3 and 6 months follow-up period. The mean initial and final bone height were 6...

Persistent left superior vena cava (PLSVC) draining into coronary sinus is typically detected incidentally during transcatheter interventions utilizing left subclavian venous approach. In our experience, we have encountered this anomaly on a few occasions and in all these cases we successfully implanted leads in the right ventricle (RV) by shaping the stylet into a 'U-shaped' or 'pigtail shaped' curve. Herein, we report a case of an adult male who underwent successful dual chamber pacemaker implantation via PLSVC through left axillary venous approach...

PURPOSE: This human case series presents the clinical and histologic results of five cases of peri-implantitis with subsequent sinus graft infections. Complications may follow maxillary sinus augmentation procedures. It is possible to have an inflammatory reaction, movement of the implant inside the sinus, formation of an insufficient quantity of osseous tissue, and the production of an oroantral fistula. Complications following maxillary subantral augmentation procedures are relatively rare; however, the risks and benefits of any surgery must be carefully evaluated at the onset...

PURPOSE: We will aim to develop implants made of a Ni-Ti shape memory alloy which can be applied for the treatment of midface fractures, such as isolated orbital floor fractures. These can then be implanted in a compressed form and unfold automatically in the body. With the help of newly developed application instruments, the implants can be applied along transnasal and transantral approaches into the maxillary sinus. Our objective is to evaluate the operation process and the functionality of these implants, already in a pre-investigation by an experienced surgeon on a phantom...

A suitable long-term anaesthetic technique was required for implantation of physiological sensors and telemetric devices in sub-adult Nile crocodiles (Crocodylus niloticus) to allow the collection of physiological data. Five Nile crocodiles with a median body mass of 24 kg were used. After manual capture, they were blindfolded and 0.2 mL (1 mg/mL) medetomidine was administered intramuscularly in four of the animals which had an estimated body mass between 20 kg and 30 kg. One crocodile with an estimated body mass of 50 kg received 0...

BACKGROUND: There is controversial evidence if atrial fibrillation (AF) alters outcome after transcatheter aortic valve implantation (TAVI). TAVI itself may promote new-onset AF (NOAF). METHODS: We performed a single-center study including 398 consecutive patients undergoing TAVI. Before TAVI, patients were divided into a sinus rhythm (SR) group (n=226, 57%) and baseline AF group (n=172, 43%) according to clinical records and electrocardiograms. Furthermore, incidence and predictors of NOAF were recorded...

Various types of implants are being commonly used for monitoring vital signals and controlling the critically ill patient's condition such as arrhythmia, sick sinus syndrome, etc. For implanting these medical devices under the skin, surgery is inevitable. These days many patients are more willing to accept interventional therapies that are less invasive, especially inserting a catheter into a blood vessel or endoscopy through a natural orifice. To be able to use interventional therapy for implanting medical devices, they will need to be small enough to fit them through a catheter or the forceps channel of an endoscope...
