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

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

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

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. Read More

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.

Physical examination revealed signs of heart failure with crackles on both lung bases, distented jugular veins, accentuated pulmonic valve closure (P2) and tricuspid regurgitation murmur. Echocardiography identified a large tumor in the left atrium, suggestive of atrial myxoma, which caused a severe functional mitral stenosis and produced severe pulmonary hypertension. Read More
