Although transcatheter arrhythmia ablation (TCA) has been performed in children for over two decades, guidelines for routine use of post-ablation transthoracic echocardiography (TTE) are absent. We sought to determine the efficacy of TTE after apparently uneventful TCA procedures in detecting adverse findings and identify predisposing factors. A retrospective review of clinical and procedural data on patients who underwent TCA for supraventricular arrhythmias from 2000 to 2015 was performed. Pre- and post-ablation TTE data were reviewed...

BACKGROUND: Active upper-limb and passive lower-limb exercise are two interventions used in the spinal cord injury (SCI) population. While the global cardiac responses have been previously studied, it is unclear how either exercise influences contractile cardiac function. Here, the cardiac contractile and volumetric responses to upper-limb (swim) and passive lower-limb exercise are investigated in rodents with a severe high-thoracic SCI. METHODS: Animals were divided into a control (CON), SCI no exercise (NO-EX), SCI passive hind-limb cycling (PHLC) or SCI swim (SWIM) group...

PURPOSE: Endovascular treatment of coarctation of aorta (CoA) by self-expandable Nitinol stents is one of the recognized treatment methods and may be an alternative to surgery or balloon-expandable stent implantation for CoA but there is little information about midterm to long term results of self-expandable stents. METHODS: Sixty-two patients with CoA (40 men), with a mean age of 30.7 ± 11 years, (range 17-63 years) underwent stent implantation with Optimed self-expandable Nitinol stents between 2005 and 2014...

The tricuspid valve (TV), although occasionally considered "neglected" is the subject of renewed and increasing interest. Factors include an awareness that tricuspid value dysfunction is influential in patient outcomes, an improving understanding of valve anatomy and function and evolving techniques available to address tricuspid regurgitation. Tricuspid regurgitation (TR) can be classified as being due to primary diseases of the valve or functional in nature, with the majority being functional. Whilst it was previously believed that such functional TR, resulting from left sided disease, would resolve after correction of the underlying pathology this is now known not to be true...

Andrei D Mǎrgulescu
Aortic valve disease [aortic stenosis (AS) and aortic regurgitation (AR)] represents an important global health problem; when severe, aortic valve disease carries poor prognosis. For AS, aortic valve replacement, either surgical or interventional, may provide definite treatment in carefully selected patients. For AR, valve surgery (either replacement or - in selected cases - aortic valve repair) remains the gold standard of care. To properly identify those patients who are candidates for surgery, the clinician has to carefully assess the severity of valve disease with an understanding of the potential pitfalls involved in these assessments...

Cross-sectional studies provide evidence of larger cardiac dimensions and mass in endurance trained than in untrained females. Much less is known regarding adaptations in cardiac function following training in untrained subjects. We aimed to study left ventricular (LV) adaptation to indoor cycling in previously untrained females, in regard of LV dimensions, mass and function. 42 sedentary females were divided into 2 equally sized groups, either training indoor cycling at regular classes at a local gym for 12 weeks, in average 2...

A 73-year-old male was brought into hospital with chest pain and inferior ST elevation on ECG. He immediately proceeded to the catheter lab for primary percutaneous coronary intervention. Angiography did not identify any culprit lesions to account for the patient's electrocardiographic changes and ongoing symptoms of chest pain. Bedside echocardiography revealed critical aortic stenosis. Intra-aortic balloon pump was inserted resulting in resolution of chest pain and ST-segment changes. The patient underwent successful aortic valve replacement without the need for coronary intervention...

BACKGROUND/AIMS: The local inflammatory response caused by coronary microembolization (CME) is the primary cause of progressive cardiac dysfunction. The PDCD4/NF-κB/TNF-α signaling pathway plays a significant role in CME-induced myocardial Inflammation. Trimetazidine (TMZ) reduces myocardial injury, caused by percutaneous coronary intervention, through relieving the CME-induced myocardial systolic dysfunction. Therefore, the present study investigated the role of TMZ pre-treatment in the protection of myocardium after CME and PDCD4/NF-κB/TNF-α in mini pigs...

An impairment of cardiac function is a key feature of cardiovascular failure associated with sepsis; however, its clinical relevance is still underestimated. Recent advancements in echocardiography in patients with septic shock enable a better characterization of septic cardiomyopathy by unmasking a severe, cardiac dysfunction even in the presence of preserved left ventricular ejection fraction. The pathophysiology of septic cardiomyopathy involves a complex mixture of systemic factors and molecular, metabolic, and structural changes of the cardiomyocytes...
