Aims: Proprotein convertase subtilisin/kexin type 9 (PCSK9) has emerged as a promising therapeutic target for the treatment of hypercholesterolaemia and atherosclerosis. PCSK9 binds to the low density lipoprotein receptor and enhances its degradation, which leads to the reduced clearance of low density lipoprotein cholesterol (LDLc) and a higher risk of atherosclerosis. In this study, the AT04A anti-PCSK9 vaccine was evaluated for its therapeutic potential in ameliorating or even preventing coronary heart disease in the atherogenic APOE*3Leiden...

Sinus of Valsalva aneurysm (SVA) is a rare cardiac anomaly, which mostly occurs in the right or noncoronary sinus of Valsalva. Left sinus of Valsava is infrequent. Unruptured SVAs are usually asymptomatic, and the diagnosis of unruptured SVA is usually accidental. A giant unruptured SVA may compress the coronary artery and cause myocardial infarction. Here, we report a rare case of a 50-year-old patient with unruptured giant left SVA causing occlusion of the left anterior descending coronary artery, which was successfully managed with our apparently unique surgical procedure...

Heart rate (HR) is associated with cardiovascular outcomes in all the stages of the cardiovascular continuum as well as in patients with pulmonary, cerebrovascular, and renal disease, sepsis, cancer, and erectile dysfunction. In patients with cardiovascular disease, but also in the general population, increased HR represents an important indicator of mortality with each acceleration of HR over 70 b.p.m. increasing the risk. In patients in sinus rhythm with chronic heart failure with reduced ejection fraction (HFrEF), a HR >70 b...

The clinical evaluation of patients with an anomalous aortic origin of a coronary artery (AAOCA), a congenital abnormality of the origin or course of a coronary artery that arises from the aorta, is challenging given its first presentation being sudden cardiac arrest in about half of the patients. Symptoms of chest pain, shortness of breath and syncope during exertion should be of concern in evaluating young athletes and nonathletes. The lack of abnormal signs on the physical exam and electrocardiogram further adds to the difficulty in establishing the diagnosis...

BACKGROUND: Categorization as a cytochrome P450 (CYP) 2C19 poor metabolizer (PM) is reported to be an independent risk factor for cardiovascular disease. Epoxyeicosatrienoic acids (EETs) are metabolites of arachidonic acid by CYP2C19 epoxygenases and anti-inflammatory properties, especially in microvascular tissues. We examined the impact of CYP2C19 polymorphisms and EETs on the patients with microvascular angina (MVA) caused by coronary microvascular dysfunction. METHODS AND RESULTS: We examined CYP2C19 genotypes in patients with MVA (n = 81)...

Objective The non-fluoroscopic navigation (NFN) is known to reduce the fluoroscopic time during catheter ablation of various arrhythmias. We aimed to study the impact of NFN over several procedural parameters during radiofrequency (RF) catheter ablation of the cavo-tricuspid isthmus (CTI) in patients with CTI-dependent atrial flutter. Methods Data about 124 consecutive patients with CTI ablation performed were retrospectively collected. The patients were divided into two groups: (1) ablation with two diagnostic catheters deployed in the coronary sinus and around the tricuspid annulus (NFN-, n = 62); (2) ablation with the same two catheters plus NFN system using cutaneous patches (NFN+, n = 62)...

BACKGROUND: The prognosis for patients with heart failure (HF), including cardiogenic shock (CS), complicating acute coronary syndrome (ACS) remains poor. OBJECTIVE: This study aimed to review the relevant literature and evaluate whether levosimendan was associated with better clinical outcomes in these patients. METHODS: We searched PubMed, EMBASE, and the Cochrane library databases for randomized controlled trials that investigated levosimendan compared with any control in patients with HF/CS complicating ACS...

RATIONALE: Ruptured aneurysm originating from the left coronary sinus of Valsalva into the left ventricle (LV) is extremely rare. Imaging features of sinus aneurysm has been commonly reported using echocardiography or angiography. Here, we report multidetector computed tomography (MDCT) findings of left sinus of Valsalva aneurysm extending into the LV and caused severe aortic regurgitation (AR) in a 44-year-old male with latent infective endocarditis. The role of MDCT in preoperative surgical planning was also emphasized...

High defibrillation threshold (DFT) and defibrillation failure can lead to intractable ventricular arrhythmias. Additional coronary sinus coil is an effective strategy to achieve marked reduction in DFT. However, physicians should retain this might prevent future coronary sinus lead placement in case the patient would develop complete left bundle branch block.

Aims: Post-operative atrial fibrillation (POAF) is a predictor of morbidity and mortality after cardiac surgery. Latent predisposing factors may reside in the epicardial adipose tissue (EAT) due to its anatomical position and high protein production rate. In order to explore a possible mechanistic link, we characterized proteins secreted by the EAT preceding the onset of POAF. Methods and results: Epicardial adipose tissue samples were collected from 76 consecutive patients with no history of AF undergoing coronary artery bypass surgery, 50 samples for proteomic analysis and 26 for gene expression studies, further divided according to development of POAF...

Single coronary artery is a rare anomaly, with a reported incidence of 0.024%. It can be diagnosed on coronary computed tomography angiography, where the presence of ostial narrowing and compression between the great vessels must be carefully excluded, since these malignant forms can lead to sudden cardiac death and other ischemic complications. We describe a case of single coronary artery arising from the right sinus of Valsalva presenting with symptoms of ischemic chest pain.

We present an uncommon and underreported complication of coronary artery bypass graft surgery: erroneous anastomosis of the left internal mammary artery to the great cardiac vein. The iatrogenic aorto-coronary arteriovenous fistula with left-to-right shunting resulted in dilation of the coronary sinus, a supporting secondary finding. Factors predisposing to this inadvertent anastomosis include an intramyocardial segment of the left anterior descending coronary artery, demonstrated in this case, as well as epicardial fat and potentially fibrosis of the underlying myocardium...

The Carillon Mitral Contour System has been studied in 3 nonrandomized trials in patients with symptomatic congestive heart failure and functional mitral regurgitation. The REDUCE FMR study is a uniquely designed, double-blind trial evaluating the impact of the Carillon device on reducing regurgitant volume, as well as assessing the safety and clinical efficacy of this device. Carillon is a coronary sinus-based indirect annuloplasty device. Eligible patients undergo an invasive venogram to assess coronary sinus vein suitability for the Carillon device...

BACKGROUND: Cardiovascular Magnetic Resonance (CMR) imaging with adenosine stress is an important diagnostic tool in patients with known or suspected coronary artery disease (CAD). However, the method is not yet established for CAD patients with pacemakers (PM) in clinical practice. A possible reason is that no recommendations exist for PM setting (paused pacing or asynchronous mode) during adenosine stress. We elaborated a protocol for rhythm management in clinical routine for PM patients that considers heart rate changes under adenosine using a test infusion of adenosine in selected patients...

INTRODUCTION: The electrophysiologic mechanism for rate-dependent PVBs associated with double potentials (DPs) was investigated in infarcted canine hearts using bipolar and intracellular microelectrode recordings. METHODS AND RESULTS: Dogs exhibiting rate-related ventricular ectopic beats (coupling interval, 390 ± 54 milliseconds) during sinus rhythm or atrial pacing were studied 4-5 days (N = 63) or 25 days (N = 16) following anterior descending coronary artery ligation...
