Kissing Balloon-Stent Technique for Simple Bifurcation Lesions.

Coronary bifurcation lesions are commonly encountered during coronary angiography. The management of bifurcation lesions remains challenging, with various bifurcation techniques being available and outcomes varying depending on the Medina classification and operator experience. We present a short case series and the outcomes of a new bifurcation technique for the management of simple Medina '0,0,1' and '0,0,1' bifurcation lesions using the kissing balloon-stent technique (kissing BS).

Shock and Awe: Successful Revascularization with Intravascular Lithotripsy in Recurrent ST-Elevation Myocardial Infarction Secondary to Stent Under-Expansion.

We report a case of recurrent ST-segment elevation myocardial infarction (STEMI) due to a previously implanted under-expanded stent with in-stent thrombosis refractory to traditional interventional techniques. We underscore the utility of bail-out shockwave intravascular lithotripsy to tackle previously under-expanded stents in this acute setting.

The Potential Role of Renal Denervation in the Management of Heart Failure.

Sympathetic nervous system activation in patients with heart failure is one of the main pathophysiologic mechanisms associated with the worse outcomes. Pharmacotherapies targeting neurohormonal activation have been at the center of heart failure management. Despite the advancement of therapies and the available treatments, heart failure continues to have an overall poor prognosis.

Intracoronary Lithotripsy Use for In-Stent Restenosis, Including Multilayer ISR.

Introduction: Intravascular lithotripsy (IVL) has been well characterized as a safe and effective method for plaque modification in the treatment of de-novo, calcific coronary artery disease. In-stent restenosis (ISR) remains a major challenge in coronary revascularization, especially "multilayer" ISR. The use of IVL in ISR remains off-label and has been described in case reports and small case series.

Optimizing Care of Patients With Right Bundle Branch Block Undergoing Transcatheter Aortic Valve Replacement.

Objectives: To evaluate the use of temporary-permanent pacemaker (TPP) in patients with right bundle branch block (RBBB) undergoing transcatheter aortic valve replacement (TAVR). We also sought to identify key predictors of permanent pacemaker (PPM) within 30 days of TAVR in this population.

Background: RBBB is a well-recognized risk factor for PPM post TAVR.

Managing coronary artery perforation after percutaneous coronary intervention.

Introduction: Coronary artery perforation is a serious complication during percutaneous coronary intervention that results in significant increase in morbidity and mortality. In this article, we provide a state-of-the-art overview of the contemporary management of coronary perforation and the possible scenarios that operators may run into during percutaneous coronary interventions.

Area Covered: Coronary perforation during percutaneous coronary intervention.

How the COVID-19 Pandemic Has Affected Cardiology Fellow Training.

With the advent of the COVID-19 pandemic in the United States, resources have been reallocated and elective cases have been deferred to minimize the spread of the disease, altering the workflow of cardiac catheterization laboratories across the country. This has in turn affected the training experience of cardiology fellows, including diminished procedure numbers and a narrow breadth of cases as they approach the end of their training before joining independent practice. It has also taken a toll on the emotional well-being of fellows as they see their colleagues, loved ones, patients or even themselves struggling with COVID-19, with some succumbing to it.
