Future Training Pathways in Percutaneous Coronary Interventions: Interventional Critical Care, Complex Coronary Interventions, and Interventional Heart Failure.

While there has been a proliferation of training and practice paradigms in the realm of noncoronary interventions, coronary disease remains the predominant pathology necessitating interventional cardiology expertise. The landscape of coronary disease has also experienced a significant transformation due to rapidly evolving technologies, clinical application of mechanical circulatory support and other device innovations, and increasing acuity and complexity of patients. The modern interventional cardiologist is subject to challenges including decreasing coronary procedural volume, need to maintain clinical and financial productivity, and often also requirements of continued scholastic pursuit.

Prevalence of Neurovascular Microemboli After Transcatheter Aortic Valve Replacement.

Background: Neurolotic sequelae after transcatheter aortic valve replacement (TAVR) can cause significant morbidity and mortality. Transcranial Doppler (TCD) imaging can show real-time high intensity transient signals (HITS), which reflect active microembolization. Although it is well known that intraprocedural microembolism occurs, it is not known if this embolic phenomenon continues in the postprocedural period.
