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

ACC 22: ICD Shock Therapies and the Burden of Ventricular Tachycardia
Author(s): Paolo Della Bella Added: 2 years ago
In this short interview from ACC.22, Dr Paolo Della Bella (San Raffaele University-Hospital, IT) joins us to discuss the findings of the PARTITA trial (NCT01547208). The aim of this study was to determine whether the burden of ventricular tachycardia correlates with ICD shock therapies and if the timing of VT ablation affects patient prognosis. Discussion Points: Rationale behind this trial … View more

The left atrial appendage (LAA) is a trabeculated structure with variable anatomy comprised of pectinate muscle, which grows out of the primary atrium before the left atrium (LA) develops. This outcropping joins the venous component of the LA by way of a bottlenecked junction, in contrast to the anatomy of the right atrial appendage which, although trabeculated, joins the atrium via a wider neck… View more

Feasibility, Safety, and Clinical Performance of Self-apposing Stents for Left Main Stenosis
Author(s): Krzysztof Pujdak , Jan Kähler , Marc Werner Added: 3 years ago
Significant stenosis of the left main (LM) coronary artery is observed in 7% of coronary angiographies.1 Coronary artery bypass grafting has traditionally been the treatment of choice. In recent years, percutaneous coronary intervention (PCI) has evolved as an alternative, especially for low and intermediate SYNTAX score patients.2 However, during PCI of bifurcation lesions, approximately 50% of… View more

Implantable cardioverter–defibrillators (ICDs) are being implanted in an ever-increasing number of patients at risk for sudden cardiac death. To ensure the efficacy of the defibrillation system, step-down defibrillation threshold (DFT) testing has traditionally been used to ensure that the ICD can appropriately detect and terminate clinical ventricular fibrillation (VF). Currently, the most… View more

Electrophysiology & Arrhythmia

Introduction Compared with patients with structurally normal hearts, there is an even greater need to suppress pathologic tachycardias in patients with congenital heart disease. The decrease in diastolic filling time and potential loss of atrioventricular (AV) synchrony are more poorly tolerated in these patients, proportionate to the degree of underlying systolic and diastolic dysfunction… View more

Abstract Coronary artery disease in patients with diabetes is frequently a diffuse process with multivessel involvement and is associated with increased risk for myocardial infarction and death. The role of percutaneous coronary intervention (PCI) versus coronary artery bypass grafting (CABG) in patients with diabetes and multivessel disease who require revascularization has been debated and… View more
