Epigenetics of paraoxonases.

Curr Opin Lipidol 2020 Jun 1. Epub 2020 Jun 1.

Princip D'Espanya, Miami Platja, Tarragona, Spain.

Purpose Of Review: Studies have shown the three-member paraoxonase (PON) multigene family to be involved in the development of a large variety of diseases with an inflammatory component. Environmental factors such as lifestyle-related factors differ widely between populations and it is important to consider that their impacts may be exerted through the epigenetic mechanisms, which connect genes, the environment and disease development and are a potential therapeutic avenue.

Recent Findings: In the review period, very little was published on epigenetics of PON2 or PON3, mostly on their diagnostic value in cancer by measuring methylation levels of these genes. Read More

Handmade trileaflet valved ePTFE right ventricle to pulmonary artery conduit - How do we do it?

Multimed Man Cardiothorac Surg 2020 May 26;2020. Epub 2020 May 26.

Department of Cardiothoracic Surgery Narayana Institute of Cardiac Sciences Bengaluru, India.

Right ventricle to pulmonary artery conduits such as homografts and pre-manufactured synthetic conduits are widely employed in the present era of complex congenital cardiac surgeries for disorders involving right ventricle - pulmonary artery discontinuity and major coronary artery crossing the right ventricular outflow tract. The key drawback of homograft conduits is the need for reoperation to replace them as a result of degeneration over time or in cases where a child has outgrown the conduit and cost is a major drawback to using commercially available conduits. The advantages of expanded polytetrafluoroethylene are its long-term durability in terms of conduit calcification/degeneration and valve stenosis/regurgitation and its cost-effectiveness. Read More

Beyond Pulmonary Vein Isolation in Nonparoxysmal Atrial Fibrillation: Posterior Wall, Vein of Marshall, Coronary Sinus, Superior Vena Cava, and Left Atrial Appendage.

Card Electrophysiol Clin 2020 Jun;12(2):219-231

Montefiore Medical Center, Albert Einstein College of Medicine, 111 East 210th Street, Bronx, NY 10467, USA. Electronic address:

The optimal ablation strategy for non-paroxysmal atrial fibrillation remains controversial. Non-PV triggers have been shown to have a major arrhythmogenic role in these patients. Common sources of non-PV triggers are: posterior wall, left atrial appendage, superior vena cava, coronary sinus, vein of Marshall, interatrial septum, crista terminalis/Eustachian ridge, and mitral and tricuspid valve annuli.

Vesicoamniotic shunting for fetal megacystis in the first trimester with a Somatex intrauterine shunt.

Arch Gynecol Obstet 2020 Jul 24;302(1):133-140. Epub 2020 May 24.

Department of Obstetrics and Prenatal Medicine, University Hospital Bonn, Venusberg-Campus 1, 53127, Bonn, Germany.

Purpose: The objective was to evaluate the feasibility of vesicoamniotic shunting (VAS) in the first trimester with the Somatex intrauterine shunt and report on complications and neonatal outcome.

Methods: Retrospective cohort study of all VAS before 14 weeks at two tertiary fetal medicine centres from 2015 to 2018 using a Somatex intrauterine shunt. All patients with a first trimester diagnosis of megacystis in male fetuses with a longitudinal bladder diameter of at least 15 mm were offered VAS. Read More

An analysis of factors influencing pulmonary artery catheter passage through the tricuspid and pulmonary valves.

JA Clin Rep 2020 May 23;6(1):38. Epub 2020 May 23.

Anesthesiology Service, Sakurabashi-Watanabe Hospital, 2-4-32 Umeda, Kita-ku, Osaka, 530-0001, Japan.

Purpose: A pulmonary artery catheter (PAC) has to pass the tricuspid and pulmonary valves for its proper placement. Although several factors were reported to hinder the placement, there have been no reports to identify the factors that prolong the individual time for passing through each valve.

Method: We individually measured the time required for a PAC to pass through the tricuspid and pulmonary valves. Read More

Ventricular septal defect jeopardizes the autograft in a Ross operation.

Ann Thorac Surg 2020 May 20. Epub 2020 May 20.

Department of Cardiac Surgery, Lens Hospital, Lens, France; Bois Bernard Private Hospital, Ramsay Générale de Santé, Bois Bernard, France.

The Ross operation is the gold standard for aortic valve replacement (AVR) in young patients as it is a durable and anticoagulation-free alternative to mechanical AVR. Careful assessment of the pulmonary valve is critical as it should become a durable neoaortic valve. Here we report the case of a patient in whom the pulmonary autograft was jeopardized by a large doubly committed ventricular septal defect (VSD), which did not offer sufficient autologous tissue for the proximal suture line.

Surgical valve repair of native pulmonary valve endocarditis using Ozaki technique.

Ann Thorac Surg 2020 May 20. Epub 2020 May 20.

Department of Anaesthesia and Critical Care, Post Graduate Institute of Medical Education and Research (PGIMER), Chandigarh, India.

Surgery for infective endocarditis in the pulmonary position is an effective method of treatment despite a very uncommon pathology and few operations being performed. We present an adult male with right sided infective endocarditis where pulmonary valve cusps were almost completely damaged. Pulmonary valve was successfully reconstructed using glutaraldehyde treated autologous pericardium by Ozaki technique. Read More

Pulmonary valve replacement after tetralogy of Fallot repair in a patient with immune thrombocytopenia.

J Card Surg 2020 May 22. Epub 2020 May 22.

Department of Cardiovascular Surgery, Keio University School of Medicine, Tokyo, Japan.

Marked thrombocytopenia causes significant bleeding in cardiovascular surgery. Herein, we describe the case of a 47-year-old woman with immune thrombocytopenia who underwent successful pulmonary valve replacement for pulmonary valve regurgitation and stenosis after complete repair of tetralogy of Fallot. Her platelet count decreased significantly to less than 5 × 10 /L on postoperative day 3, thus multiple platelet transfusions were given. Read More
