BACKGROUND: Transcatheter mitral valve-in-valve (TMVIV) or valve-in-ring (TMVIR) replacement has shown early promise in patients deemed poor surgical candidates as a less invasive alternative to conventional reoperative mitral valve (MV) replacement. OBJECTIVE: This retrospective, single-center study reviewed the procedural outcomes of all TMVIV and TMVIR procedures between 2013-2018 at a large tertiary referral center serving the southeastern United States. An analysis of patient safety measures was also performed, with a retrospective assessment of relative procedural safety that included preoperative risk stratification and postoperative mortality predictors, operative time, average blood loss, length of hospital stay, and readmission rates...

Under the hypothesis that increased extracellular sodium induces sustained neuronal excitability with the onset and progression of migraine, this study evaluates dynamic in vivo Na fluxes in the brain of a preclinical rodent analogue of migraine. Ultra-high field Na MRI at 21.1 T has demonstrated potential to quantify sodium concentrations with good spatial and temporal resolution following the onset of central sensitization. Sprague-Dawley male rats with implanted intraperitoneal (IP) lines were studied by MRI before and after an in situ injection of 10 mg/kg of nitroglycerin (NTG) versus vehicle and saline controls...

As the creation and utilization of new implantable devices increases, so does the need for interventionalists to devise unique retrieval mechanisms. This report describes the first endovascular retrieval of a CardioMEMS heart failure monitoring device. A 20-mm gooseneck snare was utilized in conjunction with a 9-French sheath and Envoy catheter for retrieval. The patient suffered no immediate postprocedural complications but died 5 days after the procedure from multiorgan failure secondary to sepsis.

Background: T follicular helper (Tfh) cells are key players in the production of antibody-producing B cells via the germinal center reaction. Therapeutic strategies targeting Tfh cells are important where antibody formation is implicated in disease, such as transplant rejection and autoimmune diseases. We investigated the impact of the immunosuppressive agent tacrolimus on human Tfh cell differentiation and function in transplant recipients. Methods: Paired blood and lymph node (LN) samples were obtained from 61 transplant recipients immediately prior to organ implantation...

The clinical performance of fillers in soft tissue augmentation depends upon their physiochemical properties, anatomical areas injected, interaction with the recipient, and the skill and experience of the physician. Scientific measures of filler properties facilitate appropriate selection of treatments for optimal treatment outcomes, and inform adjustments to treatments that improve patient safety and aesthetic outcomes. The rheological properties of calcium hydroxylapatite (CaHA), elastic modulus (G') and viscosity, coupled with its capacity to offer both immediate results and continued stimulation of collagen type I deposition, support its distinction as an ideal treatment for the volume loss characteristic of aging...

The aim of the present study was to consider the long-term midfacial mucosal outcome around final prosthetic restorations on dental implants placed and loaded immediately after tooth extractions. A total of 42 patients requiring tooth extractions were recruited, and 142 teeth were extracted. Based on the amount of keratinized mucosa (KM), implants were categorized into group A (KM ≥ 2 mm; n = 61) or group B (KM < 2 mm; n = 62). In both groups, all patients received temporary prosthetic restorations immediately after the surgical procedure...

Several growth factors (GFs) are expressed as tendons heal, but it remains unknown whether their combined application enhances the healing process. This matter was addressed by applying a combination of basic fibroblast growth factor (bFGF), bone morphogenetic protein 12 (BMP-12) and transforming growth factor beta 1 (TGFβ1) in a rat Achilles tendon transection model. GFs were applied in one of the three following ways: i) direct application of all three factors at the time of surgery; ii) sequential, tiered percutaneous injection of individual factors immediately after surgery, 48 h and 96 h later; iii) load of all three factors onto a collagen sponge implanted at the time of surgery...

Cisterna magna cannulation (CMc) is a straightforward procedure that enables direct access to the cerebrospinal fluid (CSF) without operative damage to the skull or the brain parenchyma. In anesthetized rodents, the exposure of the dura mater by blunt dissection of the neck muscles allows the insertion of a cannula into the cisterna magna (CM). The cannula, composed either by a fine beveled needle or borosilicate capillary, is attached via a polyethylene (PE) tube to a syringe. Using a syringe pump, molecules can then be injected at controlled rates directly into the CM, which is continuous with the subarachnoid space...

BACKGROUND: There is concern that the right atrial lesions of the Maze procedure lead to more permanent pacemakers postoperatively and that they provide little therapeutic advantage over left atrial lesions alone. METHODS: A discussion of the pertinent anatomy related to atrial fibrillation and the performance of the Maze procedure, the potential ways that the specialized conduction system could theoretically be damaged by the procedure, non-procedure-related causes for increased postoperative pacemaker requirements, and the basis for the efficacy of the right atrial lesions of the Maze procedure are presented...

Underexpansion of an aortic bioprosthetic valve is common after transcatheter aortic valve replacement (TAVR). Significant discrepancy between invasive hemodynamic gradients and echocardiographic Doppler gradients in an underexpanded bioprosthesis can be attributed to pressure recovery phenomenon. This case emphasizes the importance of echocardiographic guidance in implantation and assessment of bioprosthetic valve during TAVR.
