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)...

The purpose of this study was to determine the impact of elevated temperature exposure in tissue banking on soft tissues. A secondary objective was to determine the relative ability of various assays to detect changes in soft tissues due to temperature deviations. Porcine pulmonary heart valve leaflets exposed to 37 °C were compared with those incubated at 52 and 67 °C for 10, 30 and 100 min. The analytical methods consisted of (1) viability assessment using the resazurin assay, (2) collagen content using the Sircol assay, and (3) permeability assessment using an electrical conductivity assay...

A 14-year-old female was referred for severe pulmonary valve insufficiency after undergoing radiofrequency ablation for a right ventricular outflow tract tachycardia that originated in the proximal pulmonary artery at 10 years of age. Clinical records indicated that ablation was guided solely by electrograms and electroanatomical mapping. Due to myocardial tissue extensions, mapping failed to identify the level of the pulmonary valve annulus, which resulted in delivery of energy on the valve proper and into the pulmonary artery...

Case: Two cases of cardiogenic unilateral pulmonary edema are reported. Both patients presented to the emergency department with dyspnea, and chest radiography revealed unilateral infiltration, which mimics pulmonary disease. However, the patients were diagnosed with cardiogenic pulmonary edema, because echocardiography showed severe mitral regurgitation with an eccentric jet. Outcome: The patients underwent mitral valve replacement and were discharged without complications...

A 32-year-old woman suffering from systemic lupus erythematosus presented with a 6-week history of progressive dyspnoea and pleuritic chest pain. Examination was normal apart from reduced air entry at the lung bases.Arterial blood gases showed hypoxaemia and chest X-ray revealed raised hemidiaphragms without any pleural effusions. Lung function showed a restrictive pathology while high-resolution chest CT and CT pulmonary angiogram were negative. Echocardiography showed normal ventricular diameters and no pericardial effusion...

BACKGROUND: Ventricular tachycardia (VT), which is related to haemodynamic and electrophysiological alterations, is an important complication in repaired tetralogy of Fallot (rTOF) patients. We defined the role of implantable cardioverter defibrillator (ICD) therapy after pulmonary valve replacement (PVR) and the implications of coexisting long QT gene mutations/polymorphisms. METHODS: From 2003 to 2016, rTOF patients with VT who received ICD implantation were enrolled...

Pulmonary regurgitation (PR) is common in patients with congenital heart defects (CHD) and contributes to morbidity and mortality in the long-term. We investigated in this retrospective analysis whether readily accessible echocardiographic parameters are useful for quantification of PR and for predicting pulmonary valve replacement (PVR) in comparison to the gold-standard phase contrast (PC) flow measurements from cardiovascular magnetic resonance (CMR). Continuous wave (CW) Doppler and colour flow images in echocardiograms from 53 patients with CHD were analysed...

Introduction: After early successful experience with transcatheter aortic valve replacement (TAVR), concept of transcatheter implantation of a new valve within a failing bioprosthetic valve emerged. Valve-in-valve (ViV) implantation seems to be a simpler option for high risk surgical patients. Methods: We performed five ViV procedures in different valve positions. We included patients with failing bioprosthetic valves with high surgical risk due to concomitant comorbidities. We performed 2 transapical ViV procedures for failing mitral bioprosthetic valves, 1 transfemoral procedure for failing pulmonary valve and 2 transfemoral ViV implantation for failing tricuspid bioprosthetic valves...

We present the rare case of a patient with pulmonary hypertension in the context of the stiff left atrial syndrome after extensive catheter ablation, a unique constellation characterized by high pulmonary artery and pulmonary artery wedge pressures due to left atrial dysfunction but normal left ventricular end-diastolic pressure, normal mitral valve, and absence pulmonary vein stenosis. This patient was surprisingly oligosymptomatic, however, which may have been due to a persistent post-puncture atrial septal defect, which may have allowed for controlled left atrial decompression, which is in line with the novel concept of the catheter-based creation of an intracardiac shunt as a treatment for heart failure...

AIMS: Patients with significant (3+/4+) aortic regurgitation (AR) require careful monitoring or valve surgery. We sought to evaluate the diagnostic performance of aortic and pulmonary flow comparison in identifying patients with significant AR, by echocardiography. METHOD: Two hundred forty-six patients with more than trivial AR were prospectively enrolled from three centers. Aortic regurgitation (AR) severity was assessed by an expert using the currently recommended integrative approach...

INTRODUCTION: The restrictive mitral valve annuloplasty (RMA) is the treatment of choice for degenerative mitral regurgitation (MR), but postoperative functional mitral stenosis remains a matter of debate. In this study, we sought to determine the impact of mitral stenosis on the functional capacity of patients. METHODS: In a cross-sectional study, 32 patients with degenerative MR who underwent RMA using a complete ring were evaluated. All participants performed treadmill exercise test and underwent echocardiographic examinations before and after exercise...

Importance: The cerebral white matter hyperintensity (WMH) is frequently noted in patients with chronic heart disease. Long-term alteration of cardiac hemodynamics might have an influence on the mechanism of cerebral WMH. Objective: To investigate the association between chronically altered cardiac hemodynamics and severity of cerebral WMH in patients with chronic valvular heart disease. Design, Setting, and Participants: This cross-sectional analysis identified 303 consecutive patients at a tertiary referral center between 2008 and 2016 who were 50 years or older, and diagnosed with severe chronic valvular heart disease and underwent cardiac catherization, echocardiography, and received brain magnetic resonance imaging...

A 58-year-old man presented with fever and chest pain 11 days after atrial fibrillation catheter ablation. The diagnosis of pericardio-oesophageal fistula was made. Aggressive surgical management was decided. The patient was managed using extracorporeal life support, aortic valve replacement and a pulmonary patch, as well as an oesophageal stent. The patient was discharged from hospital approximately 2 months later. The use of a pulmonary patch is a rare but a highly effective technique that can be used in this indication...

Aims: Pulmonary hypertension (PH) is common in severe symptomatic left-sided valvular disease, particularly in aging populations. Inconsistent results have been reported concerning the association between PH and adverse outcomes after aortic valve replacement for aortic stenosis (AS). We therefore retrospectively investigated the prognostic significance of PH using peak tricuspid regurgitation velocity (TRV), as defined by the current European Society of Cardiology (ESC)/European Respiratory Society (ERS) guidelines, in a large cohort of patients with severe AS...

AIM: To determine whether the need for additional tricuspid valve repair is an independent risk factor when surgery is required for a left-sided heart disease. METHODS: One hundred and eighty patients (68 ± 12 years, 79 males) underwent tricuspid annuoplasty. Cox proportional-hazards regression model for multivariate analysis was performed for variables found significant in univariate analyses. RESULTS: Tricuspid regurgitation etiology was functional in 154 cases (86%), organic in 16 cases (9%), and mixed in 10 cases (6%), respectively...
