Cardiac surgery is associated with a significant risk of morbidity and mortality. In the UK, over 30,000 patients per year undergo cardiac surgery, with a hospital mortality of approximately 2.5% for coronary artery bypass grafting (CABG). Other procedures, such as cardiac valve surgery, may have higher mortality rates. Cardiac surgery is also associated with major morbidities, such as stroke,…

Magnetic resonance imaging (MRI) has become an important non-invasive imaging modality in the evaluation of cardiovascular diseases because of advances in scanner hardware, coil technology, parallel-imaging techniques and MRI sequences, all of which facilitate the rapid acquisition of high-quality images. Several scientific studies validated the use of MRI in cardiovascular diseases and showed…

Cardiac resynchronisation therapy (CRT) has achieved widespread approval as a safe and efficient therapeutic strategy for medically refractory congestive heart failure (CHF). The standard indications for CRT include patients with advanced heart failure and evidence of systolic dysfunction (ejection fraction [EF] ≤35%), conduction tissue disease (QRS duration ≥120ms) and marked cardiac symptoms …

Hairy/enhancer-of-split related with YRPW motif proteins, known as Hey family, were reported to encode a downstream transcription factor of Notch and ALK1 signalling pathways. Among the three Hey family members (Hey1, Hey2, HeyL), Hey2 null mice show postnatal lethality with various cardiac malformations, ventricular septum defect, right…

Historically pregnancy has been viewed as only clinically relevant to women and for the relatively brief time from conception to the puerperium. However it is now clear that events during pregnancy have much longer-term implications, particularly for cardiovascular health, both for the mother and her offspring.
Pregnancy complications such as hypertension and preterm birth appear to serve as a…

Sudden cardiac arrest (SCA) can be defined as the abrupt cessation of cardiac activity due to an underlying cardiac cause, occurring instantaneously in a previously stable patient and in the absence of non-cardiovascular causes (e.g., trauma, intoxication, drowning, electrocution).1,2 SCA will lead to loss of consciousness within the minute due to insufficient cerebral perfusion. If no immediate…

Abstract
Cardiac paragangliomas are the rarest primary cardiac tumours and account for less than one percent of cases. A 24-year-old man presented with complaints of sudden onset of chest pain. The pain started suddenly when he was skiing halfway down the slope and went into a tuck position. Physical examination was significant for elevated jugular venous distension. His electrocardiogram…

Radiation Dose Concerns in Cardiac Computed Tomography
Computed tomography (CT) utilisation for general medical imaging and for dedicated cardiac indications has come under a great deal of scrutiny in the past few years.1–3 Concern has arisen due to both the increased utilisation of CT, with more than 70 million scans performed in the US in 2007, and the increasing radiation dose. A recent…

Percutaneous coronary angioplasty with stenting is commonly used for treatment of symptomatic coronary artery disease (CAD). The introduction of stents has reduced the incidence of restenosis, one of the major drawbacks of coronary angioplasty, and proved to be an alternative treatment for bypass surgery. Recently, drug-eluting stents were introduced as a means to lower restenosis rates even…
