REVIEW
Mark J Kearns, Keith R Walley
Cardiac tamponade is a medical emergency that can be readily reversed with timely recognition and appropriate intervention. The clinical diagnosis of cardiac tamponade requires synthesis of a constellation of otherwise non-specific features, based on an understanding of the underlying pathophysiology. Whereas echocardiographic examination is a central component of diagnosis, alone it is insufficient to establish the physiologic diagnosis of hemodynamically significant cardiac tamponade. The hemodynamic diagnosis of cardiac tamponade requires clinical evidence of low cardiac output and stroke volume in the setting of elevated cardiac filling pressures, with evidence of increased sympathetic tone (tachycardia, peripheral vasoconstriction, etc), and exclusion of other causes of shock as the primary problem (particularly cardiogenic shock)...

In neonates requiring balloon aortic valvuloplasty, both anterograde and retrograde approaches are feasible. A recent comparison of these two approaches is lacking. A retrospective cohort study of neonates at a single center undergoing BAV from 9/00 to 7/14 was performed. Records were reviewed including pre- and post-intervention echocardiograms and catheterization data. Comparisons of acute efficacy and procedural safety were made based on type of approach utilized. Forty-two neonates underwent BAV. Eleven cases utilized exclusively an anterograde approach, while 31 included a retrograde approach (including 4 with both approaches used)...

OBJECTIVES: Mitral valve (MV) repairs have been performed in paediatric patients with congenital MV stenosis. However, congenital MV stenosis lesions are a heterogeneous group of lesions, and their repair remains challenging. METHODS: From March 1999 to September 2014, MV repair was performed in 22 patients with congenital MV stenosis. The median age was 10.3 months (ranging from 22 days to 9.1 years), and the mean body weight was 7.9 ± 4.0 kg at the time of the operation...

Aims: Antegrade-transseptal approach to treat left ventricular tachyarrhythmia (LVT) is useful and widespread. Meanwhile, Mitraclip has been recently introduced as an alternative to mitral valve surgery for severe mitral regurgitation, usually coexisting with ventricular arrhythmias. However, data on the antegrade approach for mapping and ablating LVT in these patients are insufficient. We evaluated the feasibility and clinical impact of the antegrade approach for LVT after Mitraclip implantation...

Valvular insufficiency affects cardiac responses and the pumping efficacy of left ventricular assist devices (LVADs) when patients undergo LVAD therapy. Knowledge of the effect of valvular regurgitation on the function of LVADs is important when treating heart failure patients. The goal of this study was to examine the effect of valvular regurgitation on the ventricular mechanics of a heart under LVAD treatment and the pumping efficacy of an LVAD using a computational model of the cardiovascular system. For this purpose, a 3D electromechanical model of failing ventricles in a human heart was coupled with a lumped-parameter model of valvular regurgitation and an LVAD-implanted vascular system...

The anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital anomaly. The usual clinical course is severe left-sided heart failure and mitral valve insufficiency presenting during the first months of life. However, in some cases, the collateral blood supply from the right coronary artery is sufficient and symptoms may be subtle or even absent. We describe a 49-year-old woman presenting with atypical chest pain during physical exertion. The exercise tolerance test and then coronary angiography by indication revealed an anomalous origin of the left coronary artery...

Intra-aortic balloon pump (IABP) is normally contraindicated in significant aortic regurgitation (AR). It causes and aggravates pre-existing AR while performing well in the event of mitral regurgitation (MR). Indirect parameters, such as the mean systolic pressure, product of heart rate and peak systolic pressure, and pressure-volume are used to quantify the effect of IABP on ventricular workload. However, to date, no studies have directly quantified the reduction in workload with IABP. The goal of this study is to examine the effect of IABP therapy on ventricular mechanics under valvular insufficiency by using a computational model of the heart...

Left ventricular non-compaction (cardiomyopathy) (LVN(C)) is a rare hereditary cardiac condition, resulting from abnormal embryonic myocardial development. While it mostly occurs as an isolated condition, association with other cardiovascular manifestations such as Ebstein anomaly (EA) has been reported. This congenital heart defect is characterized by downward displacement of the tricuspid valve and leads to diminished ventricular size and function. In an autosomal dominant LVN(C) family consisting of five affected individuals, of which two also presented with EA and three with mitral valve insufficiency, we pursued the genetic disease cause using whole exome sequencing (WES)...

AIMS: Evaluation of aortic stenosis(AS) is based on measurement of mean transvalvular gradient(MPG), flow velocity(vmax) and aortic valve area(AVA). Objective of the present study was to analyse the impact of systemic hemodynamic variables and concomitant mitral regurgitation(MR) on aortic MPG, vmax and AVA in severe AS. METHODS AND RESULTS: A pulsatile circulatory model was designed to study function and interdependence of stenotic aortic and insufficient mitral prosthetic valves (n=8; effective regurgitation orifice (EROA)<0...

We report a 15-month-old female with unruptured noncoronary sinus of Valsalva anreurysm (SOVA) associated with quadricuspid aortic valve, ascending aortic aneurysm (AAA), moderate aortic insufficiency, mild mitral insufficiency, genetic leukoencepaholpathy, developmental delay and mild mixed aminoaciduria. She was referred for evaluation of a cardiac murmur. Initial echocardiographic examination showed the aneurysm as a round cyst in the right atrium which changed in size during systole and diastole. As to the best of our knowledge, this is the first report of association of SOVA, quadricuspid aortic valve, AAA and genetic leukoencephalopathy in an infant...

Double orifice left atrioventricular valve (DOLAVV) or double orifice mitral valve (DOMV) is a rare congenital cardiac anomaly manifesting either as an isolated lesion (mitral stenosis or mitral insufficiency) or in association with other congenital cardiac defects. Signs of mitral valve disease are usually present along with the symptoms of associated coexistent congenital heart diseases. Mitral insufficiency due to annular dilatation is seen when DOLAVV is associated with endocardial cushion defects. Surgical intervention like mitral valve repair or replacement is required in 50% of patients and yields good results...

Functional tricuspid valve (TV) regurgitation secondary to left heart disease (e.g. mitral insufficiency and stenosis) is observed in 75% of the patients with TV regurgitation and is thus the most common etiology; therefore, the majority of patients who require TV surgery, undergo concomitant mitral and/or aortic valve surgery. Uncorrected moderate and severe TV regurgitation may persist or even worsen after mitral valve surgery, leading to progressive heart failure and death. Patients with moderate to severe TV regurgitation show a 3-year survival rate of 40%...
