Pulmonary Vein Isolation and Pacemaker Implantation in a Patient with Dextrocardia Situs Inversus.

Int Heart J 2021 Jul 17. Epub 2021 Jul 17.

Department of Cardiovascular Medicine, National Cerebral and Cardiovascular Center.

A 70-year-old female with dextrocardia with situs inversus (DSI) totalis and inferior vena cava occlusion underwent radiofrequency catheter ablation because she had symptomatic paroxysmal atrial fibrillation (AF). Careful preoperative examination made successful pulmonary vein isolation through the left jugular vein approach. One-year later, however, AF recurred, and symptomatic sinus bradycardia or junctional bradycardia often occurred. Read More

and blood compatibility of concentrated polymer brushes.

J Mater Chem B 2021 Jul;9(29):5794-5804

Soft Materials Chemistry, Institute for Materials Chemistry and Engineering, Kyushu University, Build. CE41, 744 Motooka Nishi-ku, Fukuoka 819-0395, Japan and Former Frontier Center for Organic Materials, Yamagata University, 4-3-16 Jonan, Yonezawa, Yamagata 992-8510, Japan.

Concentrated polymer brushes (CPBs) and semi-dilute polymer brushes (SDPBs) of poly(2-hydroxyethyl methacrylate), poly(2-hydroxyethyl acrylate), poly[poly(ethylene glycol)methyl ether methacrylate] (PPEGMA) and poly(2-methoxyetyl acrylate) were prepared on silica particles and silicon wafers by surface-initiated atom transfer radical polymerization (SI-ATRP). In order to evaluate in vitro blood compatibility, plasma protein adsorption on the brushes was quantified with a BCA protein assay, and the adsorbed proteins on the brushes were identified using high-performance liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). All four CPBs displayed much less protein adsorption than their corresponding SDPBs. Read More

Transcatheter treatment by valve-in-valve and valve-in-ring implantation for prosthetic tricuspid valve dysfunction.

Wien Klin Wochenschr 2021 Mar 31. Epub 2021 Mar 31.

Department of Cardiology, Medical University of Vienna, Waehringer Guertel 18-20, 1090, Vienna, Austria.

Valve degeneration after surgical tricuspid valve replacement or repair is frequent and may require repeat replacement/repair. For high-risk patients, transcatheter valve-in-valve and valve-in-ring procedures have emerged as valuable treatment alternatives. Preprocedural transthoracic echocardiography is the method of choice to detect malfunction of the prosthesis including degenerative stenosis and/or regurgitation requiring reintervention. Read More

Early complications of translumbar cannulation of the inferior vena cava as a quick, last-chance method of gaining access for hemodialysis. Ten years of experience in one clinical center.

Wideochir Inne Tech Maloinwazyjne 2021 Mar 13;16(1):282-288. Epub 2020 Oct 13.

Warmian-Masurian Cancer Center of the Ministry of the Interior and Administration's Hospital, Olsztyn, Poland.

Introduction: The gold standard of vascular access for chronic hemodialysis patients is the arteriovenous fistula (AVF). If an AVF cannot be created, the hemodialysis catheter can be inserted into the internal jugular, femoral or subclavian vein. After exhausting the abovementioned standard accesses, translumbar access to the inferior vena cava (IVC) is considered a quick, last-chance and rescue method. Read More

Totally implantable venous access port insertion via open Seldinger approach of the internal jugular vein-a retrospective risk stratification of 500 consecutive patients.

Langenbecks Arch Surg 2021 May 7;406(3):903-910. Epub 2021 Feb 7.

Department of General, Visceral and Transplant Surgery, University Hospital Münster, Waldeyerstrasse 1, 48149, Münster, Germany.

Purpose: Modern oncological treatment algorithms require a central venous device in form of a totally implantable venous access port (TIVAP). While most commonly used techniques are surgical cutdown of the cephalic vein or percutaneous puncture of the subclavian vein, there are a relevant number of patients in which an additional strategy is needed. The aim of the current study is to present a surgical technique for TIVAP implantation via an open Seldinger approach of the internal jugular vein and to characterize risk factors, associated with primary failure as well as short- (< 30 days) and long-term (> 30 days) complications.

Dynamic extracorporeal life support: A novel management modality in temporary cardio-circulatory assistance.

Artif Organs 2021 Apr 29;45(4):427-434. Epub 2020 Dec 29.

Cardio-Thoracic Surgery Department, Heart and Vascular Centre, Maastricht University Medical Centre (MUMC), Maastricht, the Netherlands.

Extracorporeal life support (ECLS) is a temporary mechanical assistance method employed in acute respiratory, cardiocirculatory, and cardio-respiratory failure, refractory to conventional treatments. Patient's hemodynamic, respiratory and metabolic condition, or situations related to ECLS support or performance, may change during ECLS treatment. Provision of an additional drainage or perfusion cannula, or even of an additional associated device, for example, transaortic suction device or intra-aortic balloon pump (IABP), may be required to improve the ECLS/patient interaction and effects.

A Novel Hybrid Silk Fibroin/Polyurethane Arteriovenous Graft for Hemodialysis: Proof-of-Concept Animal Study in an Ovine Model.

Adv Healthc Mater 2020 10 11;9(20):e2000794. Epub 2020 Sep 11.

Department of Health, Animal Science and Food Safety, Università degli Studi di Milano, Milano, 20122, Italy.

To solve the problem of vascular access failure, a novel semi-degradable hybrid vascular graft, manufactured by electrospinning using silk fibroin and polyurethane (Silkothane), has been previously developed and characterized in vitro. This proof-of-concept animal study aims at evaluating the performances of Silkothane grafts in a sheep model of arteriovenous shunt, in terms of patency and short-term remodeling. Nine Silkothane grafts are implanted between the common carotid artery and the external jugular vein of nine sheep, examined by palpation three times per week, by echo-color Doppler every two weeks, and euthanized at 30, 60, and 90 days (N = 3 per group).

A Dual-Lumen Percutaneous Cannula for Managing Refractory Right Ventricular Failure.

ASAIO J 2020 08;66(8):915-921

Division of Cardiothoracic Surgery, Department of Surgery, Medical College of Wisconsin, Milwaukee, Wisconsin.

A right ventricular assist device (RVAD) using a dual-lumen percutaneous cannula inserted through the right internal jugular vein (IJV) might improve weaning in patients with refractory right ventricular (RV) failure. However, the reported experience with this cannula is limited. We reviewed the records of all patients receiving RVAD support with this new dual-lumen cannula at our institution between April 2017 and February 2019. Read More

Nicotine Self-Administration Induces Plastic Changes to Nicotinic Receptors in Medial Habenula.

eNeuro 2020 Jul/Aug;7(4). Epub 2020 Aug 3.

Department of Physiology and Pharmacology, Wake Forest University School of Medicine, Winston-Salem, NC 27157

Chronic nicotine upregulates nicotinic acetylcholine receptors (nAChRs) throughout the brain, and reducing their activity may promote somatic and affective states that lead to nicotine seeking. nAChRs are functionally upregulated in animal models using passive nicotine administration, but whether/how it occurs in response to volitional nicotine intake is unknown. The distinction is critical, as drug self-administration (SA) can induce neurotransmission and cellular excitability changes that passive drug administration does not. Read More
