Operative mortality of Stanford type A aortic dissection( AAD) repair with previous cardiac surgery is high, especially with previous coronary artery bypass grafting. We report an extremely rare case of AAD related to the PAS-Port system. A 68-year-old male patient on dialysis was admitted to our hospital with a diagnosis of AAD. Half a year before he had undergone off-pump coronary artery bypass grafting using PAS-Port system for a proximal anastomosis of a vein graft. Urgent graft replacement of the ascending aorta was performed, and the proximal anastomotic site of the vein graft was attached to the prosthetic graft...

BACKGROUND/AIM: To address the question as to whether immersion pulmonary oedema (IPO) may be a common cause of death in triathlons, markers of swimming-induced pulmonary oedema (SIPO) susceptibility were sought in triathletes' postmortem examinations. METHODS: Deaths while training for or during triathlon events in the USA and Canada from October 2008 to November 2015 were identified, and postmortem reports requested. We assessed obvious causes of death; the prevalence of left ventricular hypertrophy (LVH); comparison with healthy triathletes...

Heart is supplied by right and left coronary arteries. Therefore, the knowledge of normal and variant anatomy of both these arteries and their configurations is indispensable for proper understanding of diagnosis and treatment of dreaded cardiac diseases. During routine cadaveric dissection, a heart of an adult female with anomalous course of Right Coronary Artery (RCA), new variant of trifurcated Left Coronary Artery (LCA) and partial atresia of circumflex (CX) artery was detected. Trifurcation of LCA into anterior interventricular, CX and a ramus intermedius without giving accessory branches has been reported...

Spontaneous coronary artery dissection is an uncommon nonatherosclerotic cause of acute coronary syndrome. It usually occurs in young women and is often associated with fibromuscular dysplasia, connective tissue diseases, and pregnancy or postpartum states. We present a case of a Syrian woman with a history of grand multiparity and recent miscarriage who presented with non-ST-elevation myocardial infarction and was found to have multivessel spontaneous coronary artery dissection and severe left ventricular dysfunction...

Cardiovascular disease (CVD) is a complex multifactorial and polygenetic disease in which the interaction of numerous genes, genetic variants, and environmental factors plays a major role in its development. In an attempt to demonstrate the association between certain genetic variants and CVD, researchers have run large genomic wild association studies (GWAS) in recent decades. These studies have correlated several genomic variants with the presence of CVD. Recently, certain polymorphisms in the phosphatase and actin regulator 1 (PHACTR1) gene have been shown to be associated with CVD (i...

OBJECTIVE:  To investigate the incidence and risk factors of acute renal failure (ARF) after operation of frozen elephant trunk and total arch replacement for acute thoracic aortic aneurysm and dissection (TAAD) with mild hypothermic circulatory arrest (MHCA), and to analyze the long-term survival rate of the patients with ARF. PATIENTS AND METHODS: From February 2009 to March 2015, patients with acute TAAD accepted operation of frozen elephant trunk and total arch replacement were enrolled...

BACKGROUND: Perivascular adipose tissue (PAT) inflammation may have a role in coronary artery disease (CAD) pathophysiology. However, most evidence has come from samples obtained during surgical procedures that may imply in some limitations. Moreover, the role of B lymphocytes and inflammation in PAT that is adjacent to unstable atheroma plaques has not been investigated in humans using morphometric measurements. OBJECTIVE: The objective of this study is to investigate the inflammation in PAT, subcutaneous, and perirenal adipose tissues (SAT and PrAT) among chronic CAD, acute CAD, and control groups in an autopsy study...

Spontaneous coronary artery dissection (SCAD) is a poorly understood and under-diagnosed entity of acute coronary syndrome, affecting predominantly young women. Relatively large series have been published in the past five years highlighting this condition, once believed to be rare. Indeed, the pathophysiology, natural history, clinical presentation, patient profile, diagnostic modalities, management and outcomes of SCAD are becoming better understood. The aim of our review is to provide a brief "state of the art" of SCAD in 2016 to help the clinician in the management of this challenging condition...

A 62-year-old man with a family history of coronary artery disease and a history of smoking, diabetes and dyslipidemia was admitted to our hospital with chest pain from acute myocardial infarction. Emergent coronary angiography was performed with intervention to a mid-right coronary occlusion with drug-eluting stent implantation. Optical coherence tomography (OCT) visualized well-apposed stent struts and no remarkable tissue protrusion, stent underexpansion, malapposition, edge dissection, and hematoma. Immediately after OCT imaging, a coronary angiogram showed a filling defect surrounded by contrast medium at the site of the stented lesion...

During their lives, women go through three different phases during which sex hormones play a fundamental role in contributing to specific cardiovascular and coronary risks. To evaluate this risk, we must take into account these various phases with their associated cardiovascular risk factors, and this during three key steps: contraception, pregnancy and menopause. Arterial risk linked to estrogen combined with progestin contraception, depends on the dosage of estrogen. The main cardiovascular risk factor responsible for increasing the risk of myocardial infarction is tobacco, especially after 35 years of age, contraindicating estrogen combined with progestin contraception at the benefit of progestin...

BACKGROUND: -Epicardial adipose tissue (EAT) volume and coronary artery disease are strongly associated, even after accounting for overall body mass. Despite its pathophysiological significance, the origin and paracrine signaling pathways that regulate EAT's formation and expansion are unclear. METHODS: -We used a novel modified mRNA (modRNA)-based screening approach to probe the effect of individual paracrine factors on epicardial progenitors in the adult heart...

Spontaneous coronary artery dissection is a poorly understood phenomenon that usually affects women during pregnancy or the immediate post-partum period. We present the case of a 60-year-old female with chronic obstructive pulmonary disease who presented with vague complaints of shortness of breath, dizziness, and weakness with a mildly elevated troponin. She denied any anginal symptoms. As part of her initial workup, a nuclear stress test revealed inferior wall reversible changes. Coronary angiography revealed spontaneous right coronary artery dissection which was treated with a drug-eluting stent...

OBJECTIVES: We evaluated the relationship between gender and angiographic and clinical outcomes in patients with severely calcified lesions who underwent orbital atherectomy. BACKGROUND: Female gender is associated with increased risk of adverse clinical events after percutaneous coronary intervention (PCI). Severe coronary artery calcification increases the complexity of PCI and increases the risk of adverse cardiac events. Orbital atherectomy is effective in plaque modification, which facilitates stent delivery and expansion...

BACKGROUND: Cardiovascular complications that can cause severe catastrophic outcomes for both the mother and the fetus are rarely seen during pregnancy. Time to diagnosis is often delayed by a low degree of suspicion and atypical presentation. We report surgical strategies in three pregnant women with cardiovascular complications. METHODS: A retrospective search from 2009 to 2016 identified three pregnant women who underwent urgent cardiac surgery. We used extracorporeal circulation (ECC) without cesarean section with careful follow-up of the fetuses during the perioperative and postoperative period...

Spontaneous coronary artery dissection is a rare condition usually encountered in young women without risk factors for atherosclerotic disease but with tortuous coronary artery or contemporary presence of fibromuscular dysplasia. Sometimes spontaneous coronary dissection occurs in patients with atherosclerotic disease, although without significant epicardial coronary artery stenosis. We report a case of a patient who underwent minimally invasive mitral valve repair, whose initially uneventful postoperative course was complicated by spontaneous coronary artery dissection of the left main causing a life threatening condition...
