Myocardial Fibrosis as a Predictor of Sudden Death in Patients With Coronary Artery Disease.
Abbasin Zegard,Osita Okafor,Joseph de Bono,Manish Kalla,Mauro Lencioni,Howard Marshall,Lucy Hudsmith,T. Qiu,Richard P. Steeds,Berthold Stegemann,Francisco Leyva +10 more
TL;DR: In this paper, the gray zone of myocardial fibrosis on cardiovascular magnetic resonance was found to be a substrate for ventricular arrhythmias (VAs) in patients with coronary artery disease (CAD) and a wide range of left ventricular ejection fractions (LVEFs).

Long-term requirement for pacemaker implantation after cardiac valve replacement surgery.
TL;DR: Valve replacement surgery was associated with a long-term risk of permanent pacemaker implantation (PPI) that was particularly high after dual and triple valve replacements.

Myocardial Fibrosis Predicts Ventricular Arrhythmias and Sudden Death After Cardiac Electronic Device Implantation.
Francisco Leyva,Abbasin Zegard,Osita Okafor,Paul W X Foley,Fraz Umar,Robin J. Taylor,Howard Marshall,Berthold Stegemann,William E. Moody,Richard P. Steeds,Brian P Halliday,Daniel Hammersley,Richard G. Jones,Sanjay K Prasad,Tian Qiu +14 more
TL;DR: In this paper , the presence of myocardial fibrosis on visual assessment (MFVA) and gray zone fibrosis (GZF) mass predicts sudden cardiac death (SCD) and ventricular fibrillation/sustained ventricular tachycardia after cardiac implantable electronic device (CIED) implantation.

Cardiac Resynchronization Therapy Using Quadripolar Versus Non-Quadripolar Left Ventricular Leads Programmed to Biventricular Pacing With Single-Site Left Ventricular Pacing: Impact on Survival and Heart Failure Hospitalization.
Francisco Leyva,Abbasin Zegard,Tian Qiu,Edmund Acquaye,Gaetano Ferrante,Jamie Walton,Howard Marshall +6 more
TL;DR: CRT using QUAD, programmed to biventricular pacing with single‐site LV pacing, is associated with a lower total mortality, cardiac mortality, and HF hospitalization and re‐intervention for LV lead displacement or phrenic nerve stimulation was associated with worse outcomes.

Ablate and pace revisited: long term survival and predictors of permanent atrial fibrillation
TL;DR: The results support the use of dual chamber pacing for paroxysmal atrial fibrillation patients after ablate and pace, and show a low overall mortality.
