Delays in Transfer For Primary PCI in STEMI
Most patients with ST-elevation myocardial infarction (STEMI) present to hospitals that are not capable of percutaneous coronary intervention (PCI). Rapid transfer to PCI-capable facilities for primary PCI may result in earlier reperfusion of the infarct artery and better clinical outcomes. However, delays in transfer may diminish the mortality benefit achieved with primary PCI in STEMI. -
BNP in Chronic Aortic Regurgitation
The most appropriate time to intervene in asymptomatic patients with chronic severe aortic regurgitation is controversial. Since brain natriuretic peptide (BNP) is released by the heart in response to increased wall stress, it has been proposed as a biomarker of the time to intervene in chronic valvular regurgitation patients. -
Assessment of Functional Severity of Coronary Lesions by CT Angiography — FFRCT
Anatomic definition of coronary artery lesions by invasive coronary angiography (ICA) or computed tomography coronary angiography (CCTA) has limitations. -

Laser Pacemaker Lead Extraction in Octogenarians
In this paper, Rodriguez and his colleagues from the Department of Cardiothoracic Surgery at the University of Miami report their experience with laser-assisted cardiac rhythm device lead extraction in a large group of patients. -
Indication for ICDs in Arrhythmogenic RV Cardiomyopathy Patients
Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is an uncommon condition with a wide spectrum of possible clinical presentations. Implantable defibrillators (ICDs) are standard therapy for treating ARVD/C patients who present with sustained ventricular tachycardia (VT) or cardiac arrest. -
