PURPOSE: Although cardiac manifestation of Behçet disease (BD) has been described in sporadic reports, its timely diagnosis remains difficult. The objective of this study was to describe early cardiac manifestations of BD. We also performed a comprehensive classification of systemic BD activity and compared their cardiac manifestations. METHODS: A prospective screening using speckle tracking echocardiography was performed in 85 patients with BD who had no history of heart disease...

Inflammation and fibrosis play an important role in the development and progression of cardiovascular diseases. Acute coronary syndrome (ACS) is caused by rupture of inflamed atherosclerotic plaque and subsequent atherothrombosis. Recent studies have shown that inflammatory markers such as C-reactive protein (CRP) can predict ACS development and have demonstrated the effectiveness of new therapeutic approaches targeting inflammation. Studies have also shown that an enhanced inflammatory response after myocardial infarction (MI) is associated with cardiac rupture, ventricular aneurysm formation, and exacerbation of left ventricular (LV) remodeling...

The 12-lead electrocardiogram (ECG) remains the most immediately accessible and widely used initial diagnostic tool for guiding management in patients with suspected myocardial infarction (MI). Although the development of high-sensitivity cardiac troponin assays has improved the rule-in and rule-out and risk stratification of acute MI without ST elevation, the immediate management of the subset of acute MI with acute coronary occlusion depends on integrating clinical presentation and ECG findings. Careful interpretation of the ECG might yield subtle features suggestive of ischemia that might facilitate more rapid triage of patients with subtle acute coronary occlusion or, conversely, in identification of ST-elevation MI mimics (pseudo ST-elevation MI patterns)...

We report a challenging case of a 81-year-old male with history of severe calcific aortic valve stenosis and aneurysmal membranous interventricular septum. The presence of anomalies in the sub-annular area can lead to valve malpositioning and its consequences. transcatheter aortic valve implantation (TAVR) in patients with aneurysm of the perimembranous interventricular septum extending into the left ventricular outflow tract has not been previously reported. This case describes a successful transfemoral TAVR with an Edwards SAPIEN XT valve (Edwards Lifesciences, Irvine, CA, United States) with such anomaly...

BACKGROUND: Cerebral vasospasm is an uncontrollable and sometimes fatal complication occurring after subarachnoid hemorrhage. However, cerebral hyperperfusion syndrome is a rare complication after subarachnoid hemorrhage. Although plain computed tomography of cerebral hyperperfusion syndrome looks similar to cerebral infarction induced by cerebral vasospasm, they should be distinguished from each other because they require completely different treatments. CASE DESCRIPTION: A 65-year-old man complained of severe headache and vomiting...

OBJECTIVES: Surgical ventricular reconstruction (SVR) is an effective treatment to improve left ventricular (LV) function in patients with ischaemic heart failure and an LV anterior-apical aneurysm. Ventricular arrhythmia (VA) is an important cause for morbidity and mortality in these patients. Therefore, encircling cryoablation targeting the VA substrate may be required. Programmed electrical stimulation (PES) can identify patients at risk for VA. The objective of this study was to evaluate the incidence and type of VA during long-term follow-up after PES-guided encircling cryoablation concomitant to SVR for primary prevention of VA...

A 51-year-old man presented with chest pain, high troponin level, inflammatory syndrome and ST-segment elevation in the anterior leads. While the transthoracic echocardiogram (TTE) showed anteroseptal hypokinesis and apical akinesis, the coronary angiogram was normal. Cardiac MR demonstrated a typical aspect of myocarditis (multiple areas of mid-myocardial late gadolinium enhancement, sparing the subendocardial layer, along with oedema). The initial diagnosis was clinically suspected myocarditis with pseudoinfarct presentation...

A 65-year-old gentleman with claudication underwent contrast-enhanced computed tomography. The scan showed occlusion of the infrarenal abdominal aorta and a 6.0 × 3.7 cm saccular zone-3 arch aneurysm. The left ventricular ejection fraction was 35% and a coronary angiogram revealed triple-vessel disease. In view of the patient's high risk with EuroSCORE II 20.34%, coronary artery surgery was combined with hybrid type I arch aneurysm repair. An endovascular stent was delivered in an antegrade manner. Open heart surgery and a hybrid type I arch intervention can be performed simultaneously through a midline sternotomy approach...

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...

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.

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...
