Cardiac pacing has evolved considerably over the years from its initial introduction as a lifesaving measure by asynchronous ventricular pacing. Pitfalls of ventricular-only pacing were recognized relatively early, which led to the introduction of atrioventricular (AV) synchronous pacing that was subjected to rigorous clinical studies.1 A meta-analysis of major pacing mode trials revealed that AV…

Pulmonary embolism (PE) is a common and serious manifestation of venous thromboembolism (VTE) and is an important cause of morbidity and mortality in the US. The incidence is estimated to be 50 per 100,000 but increases to 500 per 100,000 in the elderly.1 There is a wide spectrum of clinical severity with mortality estimates of 1–2 % in stable individuals and up to 30 % in patients presenting…

Pediatric interventional cardiology was born 40 years ago in 1966, when William Rashkind developed balloon septostomy in neonates with transposition of the great arteries.1 Almost a decade later, Andreas Gruentzig developed coronary angioplasty (between 1972 and 1976), which heralded an explosive era of interventional therapy for adults with heart disease, overshadowing the advances in…

Transvenous catheter ablation has become a curative treatment for many arrhythmias. Knowing the precise catheter location in relation to true cardiac anatomy will benefit catheter ablation procedures. A novel electroanatomic mapping system (CartoMerge™, Biosense Webster) with the capability of integrating pre-procedural computed tomography (CT) or magnetic resonance (MR) images with…

Degenerative calcific aortic stenosis (AS) is one of the most common valvular heart diseases, affecting >3% of those aged >65 years in the West.1 As a result of an aging population, the prevalence of AS is expected to increase. Severe AS causes chronic pressure overload of the left ventricle (LV), resulting in LV hypertrophy (LVH), diastolic dysfunction, an increase in the size of the left…

Numerous clinical trials involving patients with severe, symptomatic heart failure and a wide QRS complex have shown benefits from cardiac resynchronization therapy (CRT). CRT can increase left ventricular ejection fraction (LVEF), decrease LV volume and mitral regurgitation, improve symptoms caused by heart failure,1-3 and may also improve mortality.4,5 Current American College of Cardiology/…

Accessory pathways are formed embryologically during cardiogenesis and may be broad, slanted, and occasionally particularly challenging to ablate. Right-and left-sided pathways are derived differently with right-sided pathways characteristically subendocardial as opposed to subepicardial. Successful ablation of right-sided pathways is frequently limited by catheter stability and ablation attempts…

Idiopathic pulmonary arterial hypertension (formerly referred to as primary pulmonary hypertension) is an uncommon yet progressively fatal disease defined by the presence of mean pulmonary artery pressure greater than 25mmHg at rest or greater than 30mmHg with exercise as tested by right heart catheterization in the absence of other etiologies for pulmonary hypertension. Across several studied…
