Genome-wide association study of degenerative mitral valve disease in Maltese dogs.

J Vet Sci 2018 Dec 4. Epub 2018 Dec 4.

Department of Veterinary Internal Medicine, College of Veterinary Medicine, Konkuk University, Seoul, 05030, Korea.

Genome-wide association study (GWAS) is a powerful tool for identifying the genetic causes of various diseases. This study conducted to identify genomic variation in Maltese dog genomes associated with degenerative mitral valve disease (DMVD) development and evaluate the association of each biological condition with DMVD in Maltese dogs. DNA was extracted from blood samples obtained from 48 Maltese dogs (32 with DMVD and 16 controls). Read More

Effect of Functional Mitral Regurgitation on Outcome in Patients Receiving Cardiac Resynchronization Therapy for Heart Failure.

Am J Cardiol 2019 Jan 26;123(1):75-83. Epub 2018 Sep 26.

Department of Cardiology, Heart Lung Center, Leiden University Medical Center, Leiden, The Netherlands. Electronic address:

Functional mitral regurgitation (FMR) is common in heart failure (HF), and negatively impacts prognosis. Cardiac resynchronization therapy (CRT) can improve FMR, but the long-term changes in and impact of FMR after CRT are still unclear. The present study investigated the prevalence, evolution and impact on mortality of FMR before and after CRT in patients with HF. Read More

Cardiac valve calcification and use of anticoagulants: Preliminary observation of a potentially modifiable risk factor.

Int J Cardiol 2018 Nov 29. Epub 2018 Nov 29.

Department of Research, Innovation and Brand Reputation, ASST Papa Giovanni XXIII, Bergamo, Italy. Electronic address:

Aims: Direct oral anticoagulant (DOAC) has been recently introduced in the clinical practice. Rather than interfering with vitamin K-dependent posttranscriptional modification of various proteins, DOACs selectively inhibit factors involved in the coagulation cascade. In particular, in contrast with Warfarin, Rivaroxabn does not interfere with activation of matrix Gla Protein (MGP), a potent vascular calcification Inhibitor. Read More

Iatrogenic occlusion of the circumflex artery and left ventricle pseudoaneurysm after mitral annuloplasty.

J Cardiol Cases 2014 Mar 13;9(3):104-105. Epub 2013 Dec 13.

Cardiovascular and Thoracic Department, Rabta Hospital, Medical University of Tunis, Tunis, Tunisia.

Ischemic iatrogenic lesions can complicate surgical procedures on the mitral valve. One of the causative mechanisms is direct injury to or distortion of the circumflex coronary artery. The risk of damaging the circumflex coronary artery depends mainly upon the proximity of that vessel to the posterior segment of the mitral annulus, and this varies from patient to patient.

Complete rupture of the anterolateral papillary muscle complicated with acute myocardial infarction due to diagonal branch occlusion.

J Cardiol Cases 2012 Apr 12;5(2):e76-e79. Epub 2012 Jan 12.

Division of Cardiovascular Surgery, Tominaga Hospital, Osaka, Japan.

It is well known that post-infarction papillary muscle rupture of the anterolateral papillary muscle is less frequent than that of the posteromedial papillary muscle. This is thought to be due to a difference in blood supply (single vs dual) of the papillary muscles. Recently, we had two cases in which occlusion of the diagonal branch of the left anterior descending artery was found to be the culprit lesion of acute myocardial infarction leading to complete rupture of the anterolateral papillary muscle.

Objective: Focusing on 3-dimensional mitral valve structure, this study investigated predictors for moderate ischemic mitral regurgitation (IMR) improvement after off-pump coronary artery bypass grafting (OPCAB).

Methods: This study included 143 patients (age 67.6 ± 7. Read More

Comprehensive and Integrative Experimentation Setup for Large Animal Hybrid Valvular Heart Surgery.

J Surg Res 2019 Feb 12;234:249-261. Epub 2018 Oct 12.

Department of Cardiac, Thoracic and Vascular Surgery, Yong Loo Lin School of Medicine, National University of Singapore, Singapore; National University Hospital, National University Health System, Singapore.

Background: Experimental surgical procedures for atrioventricular valves present promising translational capabilities, and preclinical studies are necessary to assess their applicability and to train young enthusiastic heart teams. Here, we present a synopsis of experimental surgical procedures on porcine models for mitral valvular (MV) and tricuspid valvular (TV) interventions; mitral valve-in-valve implantation (MViV), transapical cardioscopic (TAC) MV replacement (MVR), TAC-MV annuloplasty, and tricuspid valve-in-a-ring (TViR) procedures.

Methods: Twenty-five (n = 25) female Yorkshire pigs of 55-65 kg is the total number used in the four approaches; seven animals underwent MViV, six TAC-MVR, six TAC-MV annuloplasty, and six TViR, respectively. Read More
