BACKGROUND: Coronary artery ectasia (CAE) is a segmental dilation of an epicardial coronary artery. Our aim was to evaluate the left atrial (LA) function in patients with CAE. METHODS: Twenty-seven consecutive patients with CAE and 33 subjects without significant coronary artery disease were included in our study. LA function was evaluated with two-dimensional speckle-tracking echocardiography (2DSTE). RESULTS: The systolic, early diastolic and late diastolic strains and strain rates were not statistically significantly different between the two groups...

BACKGROUND: Effective regurgitant orifice area (EROA), calculated from the vena contracta width (VCW) as the narrowest portion of the proximal regurgitant jet, might be used to estimate severity of mitral regurgitation. However, this simplified assumption only holds when the EROA is circular, which might not be true in dogs with myxomatous mitral valve disease (MMVD). HYPOTHESIS: Effective regurgitant orifice area in dogs with MMVD is noncircular, and using color Doppler real-time 3-dimensional (RT3D) echocardiography, measured EROA in the en face view will be significantly different from calculated EROA...

OBJECTIVES: We sought to investigate a new angiographic method for aortic regurgitation (AR) severity assessment in the setting of transcatheter aortic valve implantation (TAVI). BACKGROUND: AR after TAVI is common but challenging to quantitate, especially in the cath-lab. METHODS: In 228 patients, AR was quantitated before and after TAVI by echocardiography and by video-densitometric analysis of aortograms. Contrast time-density curves for the aortic root (the reference region) and the left ventricular outflow tract, LVOT were generated...

Antegrade balloon aortic valvuloplasty (BAV) may be more effective than retrograde BAV. However, early restenosis is found inconstantly within three months after BAV. To evaluate the factor of ER after intracardiac echocardiogram (ICE) guided Antegrade BAV, fifty patients with severe aortic stenosis (AS) underwent BAV procedures with ICE. ER was defined as mean aortic valve pressure gradient (PG) >40 mmHg. During one-year follow-up period, 6 patients died and 2 patients underwent aortic valve replacement...

PURPOSE: To introduce a case of ciliary detachment with primary pulmonary hypertension (PPH). METHODS: The clinical manifestations of a case of ciliary detachment with PPH were addressed by comprehensive examination including ultrasound biological microscope (UBM), intraocular pressure, color fundus photographs, fluorescence fundus angiography (FFA). In addition, echocardiography is used to measure primary pulmonary pressure. RESULTS: When the echocardiography displayed a systolic pulmonary arterial pressure of 106 mmHg, UBM exhibited ciliochoroidal detachment, as well as peripheral retinal effusion and non-perfusion areas in FFA...

Decreased coaptation height in adults has been identified as a marker of early valve failure. We evaluated aortic valve coaptation and effective height in healthy children and in children with a ventricular septal defect (VSD) with aortic cusp prolapse (ACP), using echocardiography. We included 45 subjects with VSD with ACP, 27 did not develop aortic regurgitation (AR) by ACP and 18 developed AR by ACP, and 83 healthy children as controls. Aortic root anatomy was estimated using the parasternal long-axis view...

AIMS: In adults with congenital heart disease (CHD) heart failure is one of the leading causes of morbidity and mortality but experience with and reported outcome of cardiac resynchronization therapy (CRT) is limited. We investigated the efficacy of CRT in adults with CHD. METHODS AND RESULTS: This was a retrospective study including 48 adults with CHD who received CRT since 2003 in four tertiary referral centres. Responders were defined as patients who showed improvement in NYHA functional class and/or systemic ventricular ejection fraction by at least one category...

Since the early 1990s human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) emerged as a global health pandemic, with sub-Saharan Africa the hardest hit. While the successful roll-out of antiretroviral (ARV) therapy provided significant relief to HIV-positive individuals, such treatment can also elicit damaging side-effects. Here especially HIV protease inhibitors (PIs) are implicated in the onset of cardio-metabolic complications such as type-2 diabetes and coronary heart disease. As there is a paucity of data regarding suitable co-treatments within this context, this preclinical study investigated whether resveratrol (RSV), aspirin (ASP) or vitamin C (VitC) co-treatment is able to blunt side-effects in a rat model of chronic PI exposure (Lopinavir/Ritonavir treatment for 4 months)...

BACKGROUND: Hemorrhagic shock and pneumonectomy causes an acute increase in pulmonary vascular resistance (PVR). The increase in PVR and right ventricular (RV) afterload leads to acute RV failure, thus reducing left ventricular (LV) preload and output. Inhaled nitric oxide (iNO) lowers PVR by relaxing pulmonary arterial smooth muscle without remarkable systemic vascular effects. We hypothesized that with hemorrhagic shock and pneumonectomy, iNO can be used to decrease PVR and mitigate right heart failure...

Infective endocarditis (IE) is a serious infectious condition with high morbidity and mortality in patients with end-stage renal disease (ESRD). It has been particularly associated with recurrent bacteremia due to vascular access via lumen catheters. The most common pathogen is Staphylococcus (S.) aureus, and most affected valve is mitral valve, which frequently calcified. Two patients with ESRD who received hemodialysis treatment via tunneled catheters, aged 56 and 88 years, were admitted with fever and high troponin level...

AIMS: While TAVI is the treatment of choice in patients with aortic stenosis considered inoperable or at high risk, interventional replacement of the mitral valve is still in the preclinical or early clinical phase. Our aim was to report on the first transcatheter double valve replacement into native valves from a transapical access. METHODS AND RESULTS: A 67-year-old, highly symptomatic female patient considered inoperable due to severe calcification of the mitral annulus and comorbidities was scheduled for transcatheter double valve replacement by the local Heart Team...

Aortic atresia with an associated ventricular septal defect and adequate sized left ventricle is extremely rare. We present two cases in which an alternate diagnosis was suggested on echocardiography because the hypoplastic aortic trunk was missed due to its small caliber. The final diagnosis was, however, clinched on dual source computed tomography, which not only showed the thin aortic trunk but also clearly depicted the coronary artery origins from the hypoplastic aortic root. To the best of our knowledge, use of multi-detector computed tomography in aortic atresia with well developed left ventricle has not been reported in literature till date...

BACKGROUND: -Biased agonism of the angiotensin receptor (AT1R) is known to promote cardiac contractility. Our laboratory indicated that these effects may be due to changes at the level of the myofilaments. However, these signaling mechanisms remain unknown. As a common finding in dilated cardiomyopathy (DCM) is a reduction in the myofilament-Ca(2+)-response, we hypothesized that β-arrestin signaling would increase myofilament-Ca(2+)-responsiveness in a model of familial DCM and improve cardiac function and morphology...

BACKGROUND: Pathophysiological responses, including cardiovascular complications, often alter with age. Cardioprotective effects of epoxyeicosatrienoic acids (EETs) toward acute myocardial ischemia-reperfusion injury have been well documented. However, biological relevance of EET-evoked cardioprotection in the ageing myocardium remains unknown. EETs are metabolized to less active metabolites by the enzyme soluble epoxide hydrolase (sEH). This study uses permanent occlusion of the left anterior descending artery (LAD) in young and aged sEH null and WT mice to compare cardiac and mitochondrial function following ischemic injury...

OBJECTIVES: The aim of this study was to describe the incidence and clinical impact of left atrial appendage thrombus (LAAT) in a population referred for transcatheter aortic valve replacement (TAVR) and to examine the role of cardiac computed tomography (CCT) in the diagnosis of LAAT. BACKGROUND: Atrial fibrillation is common in patients undergoing TAVR. Embolization of LAAT is a potential mechanism of periprocedural stroke. The incidence and clinical impact of LAAT in a TAVR cohort have not been reported, and the optimal method for diagnosing LAAT remains unclear...
