Percutaneous transluminal coronary angioplasty (PTCA) was introduced in the late 1970s as an alternative to coronary artery bypass graft surgery for coronary revascularization; since then, it has been accepted as a safe, reliable, and effective treatment for coronary artery disease, and its use has spread worldwide.Hyperlipidemia is a major cause of cardiovascular disease despite the availability of first-line cholesterol lowering agents such as statins. Although statin therapy is very efficient to reduce cholesterol, nearly 10-20% of individuals on statins, experience side effects, such myopathy, which hinder the drugs ability to achieve target low-density lipoprotein (LDL) cholesterol (LDL-C) levels. Statin-intolerant patients require more effective therapies for lowering LDL-C. As proprotein convertase subtilisin kexin type 9 (PCSK9) promotes the degradation of the LDL receptor (LDLR) and prevents it from recycling to the membrane, a new therapeutic approach to lowering LDL-C acts by blocking LDL-receptor degradation by serum PCSK9. Humanized monoclonal antibodies which target PCSK9 and its interaction with the LDL receptor (REGN727/SAR23653, AMG145, and RN316), as well as agents that inhibit PCSK9 synthesis, such as ALN-PCS, are now in clinical trials. The latter is a small interfering RNA (siRNA) that directs sequence-specific messenger RNA for PCSK9 leading to reduced hepatocyte-specific synthesis of PCSK9. Ongoing phase III trials’ results are awaited with great interest in order to define these agents’ long-term safety, tolerability and efficacy for reducing cardiovascular events.Sequential surgical thoracoscopic and electrophysiological (EP) ablation is gaining popularity as a novel approach for the treatment of patients with stand-alone, persistent and long standing persistent atrial fibrillation (AF).The measurement of fractional flow reserve (FFR) has been proven useful in evaluating whether or not to perform percutaneous coronary intervention (PCI), especially in the case of “intermediate” stenosis. Nowadays, the indication of its usefulness has been expanded. While coronary angiography remains the cornerstone for assessment of epicardial coronary artery lesions in the catheterization laboratory, FFR-guided coronary treatment has established its usefulness especially after FAME 1 & 2 trials.Atrial Fibrillation (AF) is associated with increased morbidity and mortality and a more severe impairment in quality of life compared with patients with congestive heart failure or myocardial infarction. Left atrial myocardial extensions, known as “myocardial sleeves”, are present in almost all pulmonary veins (PVs), and have been recognized as the main source of triggers that initiate and perpetuate AF.

The Gerbode defect is characterized by a perimembranous ventricular septal defect between the left ventricle and the right atrium. This intracardiac shunt is a congenital defect but may be iatrogenic after valve surgery or atrioventricular node ablation, may be the result of endocarditis or may be traumatic. It is really rarely encountered as sequelae of non-penetrating heart trauma, and their clinical manifestations may often be unrecognized in the multi-injured patient. However, they are serious complications, and their diagnostic approach is not always feasible. We hereby present a case of a young man with the left ventricle to the right atrium communication after blunt thoracic trauma due to a car accident and concomitant rupture of the thoracic aorta. We present also the case and the ways of treatment according to the international bibliography.

The Takotsubo syndrome or apical ballooning, also known as “broken heart syndrome” (BHS) among a variety of suggested names, was first described by Sato et al in the Japanese population approximately 20 years ago. Since then, it has been increasingly recognized in other countries and in 2006 it was classified as a type of stress cardiomyopathy among acquired cardiomyopathies. The prevalence of the BHS is estimated to be 1-2% of patients presenting with an acute coronary syndrome but higher rates have been reported lately, due to a wider recognition of the syndrome. One of the hallmarks of the BHS is a strict predilection for postmenopausal women (over 90% in most series), whereas men account for less than 10% of cases. It has also been reported that among BHS patients, 43% had a preceding acute medical condition and 27% had a severe emotional or physical stressor associated with a “fight or flight” hypersympathetic response... (excerpt)Patients with diabetes mellitus have more advanced coronary artery disease (CAD) eith greater plaque burden, longer lesions, smaller, more diffusely diseased vessels. On the other hand, approximately 25% undergoing percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) have diabetes. Regardless of the type of revascularization, diabetic patients have worse prognosis compared to patients without diabetes. With regards to PCI, diabetic patients have a higher restenosis rate and are at greater risk for myocardial infarction and stent thrombosis than patients without diabetes... (excerpt)
