BACKGROUND: Left ventricular aneurysm (LVA) relates to the worse prognosis of patients with myocardial infarction despite successful reperfusion treatment. There is no evidence of early detectable biomarkers to predict risk for the future development of LVA. The aim of our study was to investigate the possible predictive value of peri-procedural hematological parameters for the LVA. METHODS: A total of 281 patients with acute anterior ST-elevated myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PPCI) were enrolled...

Marfan syndrome, bicuspid aortic valve, and/or coarctation of the aorta are associated with medial abnormalities of the ascending aortic or para-coarctation aorta. Medial abnormalities in the ascending aorta are prevalent in other type of patients with a variety of CHDs such as single ventricle, persistent truncus arteriosus, transposition of the great arteries, hypoplastic left heart syndrome, and tetralogy of Fallot, encompassing a wide age range and may predispose to dilatation, aneurysm, and rapture necessitating aortic valve and root surgery...

Rationale: Aortic valve disease is a cell-mediated process without effective pharmacotherapy. C-type natriuretic peptide (CNP) inhibits myofibrogenesis and osteogenesis of cultured valve interstitial cells (VICs), and is downregulated in stenotic aortic valves. However, it is unknown whether CNP signaling regulates aortic valve health in vivo. Objective: To determine whether a deficient CNP signaling axis in mice causes accelerated progression of aortic valve disease. Methods and Results: In cultured porcine VICs, CNP inhibited pathological differentiation via the guanylate cyclase natriuretic peptide receptor 2 (NPR2) and not the G-protein-coupled clearance receptor NPR3...

This article addresses the intensive care unit (ICU) management of patients with aneurysmal subarachnoid hemorrhage (SAH), with an emphasis on the prevention of cerebral vasospasm and delayed cerebral ischemia (DCI), which are major contributors to morbidity and mortality. Interventions addressing various steps in the development of vasospasm have been attempted, with variable success. Enteral nimodipine remains the only approved measure to potentially prevent DCI. Since oral and intravenous administrations are limited by hypotension, direct administration via sustained-release pellets and intraventricular administration of sustained-release microparticles are being investigated...

Different surgical techniques, each with its own advantages and disadvantages, have been used to reverse adverse left ventricular remodeling due to postinfarction left ventricular aneurysm. The most appropriate surgical technique depends on the location and size of the aneurysm and the scarred tissue, the patient's preoperative characteristics, and surgeon preference. This review covers the reconstructive surgical techniques for postinfarction left ventricular aneurysm.

A 70-year old Caucasian man with recurrent ventricular tachycardia and progressive biventricular failure attributed to arrhythmogenic right ventricular cardiomyopathy/dysplasia was evaluated for heart transplantation. Cardiac ventriculography revealed an abnormal left ventricle with five saccular aneurysms. Heart transplantation was performed. Pathology of the explanted heart showed multifocal sarcoid granulomas. Replacement fibrosis was widespread in both ventricles and associated with saccular aneurysms. No genetic basis was identified...

OBJECTIVE Shunt-dependent hydrocephalus is an important cause of morbidity following aneurysmal subarachnoid hemorrhage (aSAH) in excess of 20% of cases. Hydrocephalus leads to prolonged hospital and ICU stays, well as to repeated surgical interventions, readmissions, and complications associated with ventriculoperitoneal (VP) shunts, including shunt failure and infection. Whether variations in surgical technique at the time of aneurysm treatment may modify rates of shunt dependency remains a matter of debate...

Current cardiovascular ultrasound mainly employs planar imaging techniques to assess function and physiology. These techniques rely on geometric assumptions, which are dependent on the imaging plane, susceptible to inter-observer variability, and may be inaccurate when studying complex diseases. Here, we developed a gated volumetric murine ultrasound technique to visualize cardiovascular motion with high spatiotemporal resolution and directly evaluate cardiovascular health. Cardiac and respiratory-gated cine loops, acquired at 1000 frames-per-second from sequential positions, were temporally registered to generate a four-dimensional (4D) dataset...

Recently, it has been reported that spontaneous left ventricular wall thickening occurs among patients with takotsubo syndrome, which affects the long-term prognosis of such patients due to cerebral and cardiac complications. We herein report two cases of transient left ventricular wall thickening with takotsubo syndrome in which sequential cardiac magnetic resonance imaging revealed the existence of edematous changes in the thickened wall. Notably, a left ventricular aneurysm was detected during the course of ventricular wall thickening and may have played a role in the development of takotsubo syndrome, a serious complication...

Cardiovascular thrombosis is rare in children and usually occurs in the presence of predisposing conditions, such as indwelling vascular catheters, tumors, aneurysms, ventricular dysfunction, or after surgery. Clots can occur in the cardiac chambers, arteries or veins, or inside conduits. Detection of thrombi is feasible with a variety of magnetic resonance imaging (MRI) techniques, including unenhanced methods but also contrast-enhanced MR angiography. In this essay we illustrate the MRI appearance of cardiovascular thrombosis in children and suggest an imaging protocol based on our clinical experience...

A 67-year-old man presented with late left ventricular free wall rupture 1 month after an extended sandwich technique through a right ventricular incision for ventricular septal rupture following an inferoposterior acute myocardial infarction. We found that residual infarcted myocardium had led to left ventricular aneurysm formation. A pericardial patch on the left ventricular side at the initial operation should have been secured further from the septal defect using a larger needle. A patch on the left ventricular side is important for complete exclusion of a free wall infarction and for decreasing the stress on the suture line securing the patch...

Left ventricular (LV) apical thrombus is a clinically important complication which can cause systemic embolization in patients with anterior acute myocardial infarction (AMI). Systolic dysfunction has been a risk factor for developing LV apical thrombus in AMI patients. However, the role of diastolic dysfunction in the development of LV apical thrombus in these patients is still unknown. We performed this study to evaluate whether diastolic dysfunction can influence the development of LV apical thrombus in anterior AMI patients...

A 66-year-old man presented with abdominal distension and pedal oedema for the past 10 years. He had history of right heart failure on several occasions in the past, and one of these admissions prompted referral to a cardiac specialist. On examination, he had markedly elevated jugular venous pressure with prominent 'y-descent', a tricuspid regurgitation murmur, gross ascites and pedal oedema. A full blood count, routine biochemical screen and serum bicarbonate levels were normal. Right ventricular angiogram revealed a 'caterpillar'-like aneurysm of the right ventricle (RV) apex (figure 1 arrow) with a dilated right ventricular outflow tract and significant tricuspid regurgitation with a dilated right atrium (see online supplementary video 1)...
