Left ventricular aneurysm and pseudoaneurysm are two complications of myocardial infarction in which the role of imaging is paramount. The authors describe a case of a true aneurysm of the posterior wall, for which cardiac magnetic resonance was useful, although only intra-operative assessment confirmed the diagnosis.

Coronary artery dissection (CD) is a rare cause of acute myocardial ischemia. It is often diagnosed by invasive coronary angiography, which is the principal diagnostic tool and gold standard in the diagnosis and triage of patients with CD. More recently, electrocardiogram-gated multidetector computerized tomography has emerged as a complementary imaging ...

Heart failure (HF) represents a major health and economic burden worldwide. In spite of best current therapy, HF progresses with unpredictable episodes of deterioration that often require hospitalisation. These episodes are often preceded by accumulation or redistribution of fluid causing haemodynamic overload on the heart. Remote and telemonitoring of the ...

The electrocardiographic diagnosis of intraventricular conduction disturbances may be hindered by the coexistence of ventricular preexcitation. In fact, the premature depolarization of ventricular myocardium through an accessory pathway tends to conceal any electrocardiographic manifestation of a bundle-branch block. However, there are several conditions favoring the diagnosis of bundle-branch block associated ...

In severe mitral regurgitation, a subset of patients who are asymptomatic may develop left ventricular decompensation before changes in echocardiographic parameters become evident. Since N-terminal brain natriuretic peptide (NT-proBNP) is used to detect early heart failure, we hypothesised that NT-proBNP would be activated in patients with mitral regurgitation. Patients submitted ...

Hospitalization for decompensated heart failure (HF) is associated with extraordinarily high rates of morbidity and mortality. Despite its high prevalence its pathophysiologic mechanisms and future risk stratification remain poorly defined and understudied. Several clinical Risk Scores to recognize high risk patients, has been purposed in the past but they are ...

To adequately address the burden imposed by heart failure, a combined approach to prevention, early detection, and management is required. Failure to adequately consider the presymptomatic pool of subjects largely accounts for the continuing burden of incident cases of symptomatic heart failure. This article reviews the rationale for the early ...

Epidemiologic, clinical, and basic research has identified several antecedent conditions that predispose individuals to heart failure and its predecessor, asymptomatic left ventricular remodeling and dysfunction (stage B heart failure). Many biochemical markers have been described that characterize the remodeling process and the development of cardiac dysfunction. Although natriuretic peptides and ...

Diabetes in pregnancy, both pre-gestational and gestational, is a frequent cause of fetal myocardial hypertrophy, partly due to fetal hyperinsulinism. In fetal life, cardiac function may be impaired, especially during diastole, as a result of decreased left ventricular distensibility and altered left atrial dynamics secondary to myocardial hypertrophy. In neonates, ...

Congenital long QT syndrome (LQTS) is an inherited disorder characterized by QT prolongation and polymorphic ventricular tachycardia known as torsade de pointes. The underlying cellular mechanism is prolonged ventricular repolarization caused by mutations in genes encoding cardiac ion channels or membrane adaptors. The disease can be diagnosed at any age ...

Nearly half of all heart failure (HF) patients have diastolic HF (DHF) or clinical HF with normal or near-normal left ventricular ejection fraction (LVEF). Although the terminology has not been clearly defined, it is increasingly being referred to as HF with preserved ejection fraction (HFPEF). The prevalence of HFPEF increases ...

Isolated noncompaction of ventricular myocardium (INVM) is a genetic cardiomyopathy due to abnormal arrest in endomyocardial embryogenesis between fetal 5th and 8th week. Noncompaction of right ventricle alone is rare. Here we present one such case where a young man presented with progressive right heart failure and atrial fibrillation. Subsequent ...

The approach to supraventricular tachycardia (SVT) diagnosis can be complex because it involves synthesizing baseline electrophysiologic features, features of the SVT, and the response(s) to pacing maneuvers. In this two-part review, we will mainly explore the latter while recognizing that neither of the former can be ignored, for they provide ...

Rigorous training remodels the heart of elite endurance athletes to produce the phenotype of the "athlete's heart." This remodeling, which advantages cardiac performance, creates challenges in the diagnosis of cardiac disorders within this population. This is particularly so for right ventricular pathologies because of the limited number of studies documenting ...

Atrial fibrillation (AF) is an arrhythmia of increasing prevalence associated with a reducible risk of stroke. We conducted a systematic review to address five questions relating to how we can best detect AF: 1. Are there useful screening tests to determine who should have a 12-lead electrocardiogram (ECG)? Potential screening ...

Nowadays, we have a better understanding of the natural history of constrictive pericarditis such as transient constriction. In addition, we have acquired the correct understanding of hemodynamic features that are unique to constrictive pericarditis. This understanding has allowed us to diagnose constrictive pericarditis reliably with Doppler echocardiography and differentiation between ...

Axial flow left ventricular assist devices (LVADs) are a significant improvement in mechanical circulatory support. However, patients with these devices experience degradation of large von Willebrand factor (vWF) multimers, which is associated with bleeding and may be caused by high shear stresses within the LVAD. In this study, we used ...

Coronary artery dissection is a rare, sometimes fatal traumatic condition, with 80% of cases affecting women. The coronary artery develops a tear, causing blood to flow between the layers, which force them apart. We describe the case of a 35-year-old multiparous woman with acute myocardial infarction secondary to right coronary ...
