Cardiac resynchronisation therapy (CRT) is a well-established non-pharmacological treatment option for patients with refractory symptomatic heart failure (HF) already under optimal medical therapy.1 CRT is founded on the principle that interventricular conduction disturbances and especially left bundle branch block (LBBB) are deleterious to cardiac performance and may contribute to the systolic… View more

I first met Mark Josephson in the early 1980s at his conference in Philadelphia, which I attended as a trainee. He was an inspiring figure, with his incisive commentary and enthusiasm for the field. It was there that I first heard Al Waldo explain entrainment, which he illustrated by drawing diagrams on a large flip chart. The discussion was spirited! Mark brought people together, then pushed… View more

Monitoring after implant of patients with cardiac implantable electronic devices (CIED) forms a part of both device and patient care, and is the responsibility of the implanting centre. Monitoring is challenged by the increasing number and technical complexity of implanted devices coupled with the increasing clinical complexity of the patient population. Current practice is based on quarterly to… View more

Patients with a cardiac implantable electronic device (CIED), like a pacemaker or a defibrillator, can be of all ages and have different types of implants. You have probably encountered at least one of these in your everyday practice. In this episode, Angelo Auricchio and Archie Rao, both specialists in this area, will discuss types of CIEDs and what they do. They will highlight potential… View more

Hypertrophic cardiomyopathy (HCM), the most common genetic cardiomyopathy, is present in one in 500 of the general population and is caused by over 1,400 mutations in at least 11 genes encoding the cardiac sarcomere.1–4 Although the majority of patients with HCM remain asymptomatic with near-normal longevity, a small, but important, subset of patients are at increased risk for a wide range of… View more

In 1885, Oscar Langendorff was the first person to describe the increase in contractility (‘Pulsverstärkung‘) that follows an extrasystole.1Langendorff experimented with spontaneously beating isolated frog hearts. He recorded the heartbeats by using a lever that transferred the contractile movements of the heart to a rotating drum. Electrical stimulation resulted in premature contractions that… View more

Despite the fact that more than 20 years have passed since the clinical introduction of cardiac resynchronisation therapy (CRT), one of the key questions – do we need an ICD for primary prevention of sudden cardiac death (SCD) in CRT patients? – is still unanswered. Prospective Randomised Controlled Trials Multiple prospective randomised controlled trials have been conducted to establish the… View more
