Atrial Septal Defects and Patent Foramen OvaleNomenclature
The atrial septum is a complex structure, with the true septum comprised of two layers containing a potential flap valve. The septum primum extends from caudal to cranial within the atria, on the left side of the septum secundum. The septum secundum is a crescent-shaped infolding of the atrial roof, extending from the anterosuperior…

Optimal cardiac function depends on appropriate rate and force of contraction, with specific cardiac regions having developed particular beat-to-beat properties depending on their individual functions. For example, isovolumetric contraction time is shorter in the right ventricle (RV) than in the left ventricle (LV). At the cellular level, cardiac function is regulated by regional cardiomyocyte…

Atrial fibrillation (AF) is the most common arrhythmia experienced in clinical practice, and is responsible for significant morbidity and mortality.1 It affects more than 6 million people in Europe.1 The lifetime risk of developing AF after the age of 40 is approximately 25 %.1 AF is a major public health burden as it is associated with an increased risk of stroke by fivefold, dementia by twofold…

Monomorphic ventricular arrhythmias (MMVA) are not uncommon in athletes,1,2 yet their presence appropriately raises concern among practitioners for possible increased risk of sudden cardiac death (SCD) during sports activity and competition. While all MMVA detected in athletes warrant further evaluation,1 a majority of MMVA in this population are likely to be benign. In some instances of so…

The term ‘flutter’ was coined to designate the visual and tactile rapid, regular atrial contraction induced by faradic stimulation in animal hearts, in contrast with irregular, vermiform contraction in atrial fibrillation (AF).1,2 On the ECG, flutter was a regular continuous undulation between QRS complexes at a cycle length (CL) of ≤250 ms (≥240 bpm). Slower tachycardias displaying discrete P…

CRT is an essential treatment for patients with heart failure and reduced ejection fraction as it can restore left ventricular (LV) electrical and mechanical synchrony. It has been shown to increase quality of life, improve functional status, reduce hospitalisation, improve LV systolic function and reduce mortality in properly selected patients.1,2 While CRT is an effective therapy, approximately…

Since the introduction of CRT more than 20 years ago, its role in mild to severe systolic heart failure has become well established. CRT has been shown to decrease mortality, reduce heart failure hospitalisations and improve functional status in patients with NYHA class II–IV heart failure and QRS prolongation, most commonly with LBBB pattern.1 One of the major limitations of CRT implementation…

Prevalence of Functional Mitral Regurgitation in Patients with Chronic Heart Failure
Secondary or functional mitral regurgitation (FMR) is a common problem in patients with chronic heart failure (HF) due to dilated cardiomyopathy, regardless of aetiology.1 FMR results from an imbalance between the closing and the tethering forces that act on the mitral valve leaflets.2,3
