The introduction of percutaneous coronary angioplasty in 1977 by Dr Andreas Grüntzig1 was one of the most remarkable achievements in the cardiology realm, opening the door to numerous advancements in percutaneous coronary interventions (PCIs). Due to advances in PCI techniques over the past four decades, catheters along with four generations of coronary stents have dramatically changed the… View more

Surgical repair has been the cornerstone of treatment for congenital heart diseases (CHD). However, cardiac catheterization has evolved from being a diagnostic modality to a therapeutic one in the past four decades. Application of catheter-based therapy has become the standard of care for some congenital heart defects, thus obviating surgery. This review will discuss congenital heart defects that… View more

Cardiogenic shock (CGS) results in inadequate end organ perfusion and is associated with high mortality. For patients presenting with CGS following myocardial infarction (MI), reported rates of mortality range between 55% and 80% despite aggressive pharmacological therapy and use of the intra-aortic balloon pump (IABP). Patients with CGS due to ventricular septal defect (VSD) or ventricular… View more

Transcatheter Edge-to-edge Repair of Severe Tricuspid Regurgitation
Author(s): Shu-I Lin , Mizuki Miura , Francesco Maisano , et al Added: 3 years ago
Moderate-to-severe tricuspid regurgitation (TR) is estimated to affect more than 1.6 million people in the US. However, fewer than 8,000 tricuspid valve operations are performed each year.1,2 There is clearly an unmet need for a tricuspid valve (TV) intervention. There has been rapid development in the field of transcatheter aortic and mitral valve interventions and percutaneous management of… View more

Cardiac computed tomography (CT) has evolved greatly over the last 20 years. This article reviews its current clinical uses, and describes some of the potential for even greater utility in the near future. Electron beam tomography (EBT) was developed 20 years ago specifically for cardiac imaging. Although the technique can quantify ventricular anatomy and function as well as myocardial perfusion… View more

Contrast echocardiography (CE) is 40 years old this year. Gamiak and Shah first described the use of ultrasound (US) contrast in 1968 during the early days of M-mode echocardiography.1 In that study, US contrast was produced by inadvertently introducing air bubbles in the indocyanine green solution that was injected into the left heart during cardiac catheterisation and observing its appearance… View more

The prevalence of heart failure and the resultant mortality has continued to rise despite increased understanding of the pathogenesis and improvement in management strategies.1 Left ventricular (LV) dysfunction is the final stage of most primary cardiovascular diseases, and greater severity is directly correlated with worse prognosis. The principal manifestation of heart failure progression is a… View more

Rhythm disorders, independent of structural congenital heart disease, have been described with myriad pediatric syndromes.Reviewing all pediatric syndromes associated with rhythm disorders is beyond the scope of this text.However, arrhythmia as a common or defining clinical feature of a pediatric syndrome is relatively rare. A representative sample of pediatric syndromes that prominently feature… View more
