Frailty is a common geriatric syndrome of increased vulnerability to adverse events. The prevalence of frailty among chronic heart failure (CHF) is high and confers a greater risk of adverse events including falls, hospitalisation and mortality. There have been few studies assessing frailty in CHF. A review of the key databases was conducted from 2004 to(More)
Atrial fibrillation (AF) is one of the most common postoperative complications following cardiac surgery. Recent evidence suggests that postoperative atrial fibrillation (POAF) may be more 'malignant' than previously thought, associated with follow-up mortality and morbidity. To evaluate the long-term survival of POAF versus No-POAF cohorts following(More)
BACKGROUND Recent results from the largest multicenter randomized trial (Shockless IMPLant Evaluation [SIMPLE]) on defibrillation threshold (DFT) testing suggest that while shock testing seems safe, it does not reduce the risk of failed shocks or prolong survival. A contemporary systematic review of DFT versus no-DFT testing at the time of implantable(More)
BACKGROUND The number of elderly patients undergoing hepatic resection for surgical treatment of benign and malignant cancers is increasing. However, there is limited clinical data on the complications and long-term survival rates associated with liver surgery in the elderly patients (≥70 years) versus younger patients for malignant liver conditions.

BACKGROUND Transcatheter aortic valve implantation (TAVI) is a feasible interventional technique for severe aortic stenosis in patients who are deemed inoperable or at high surgical risk. There is limited evidence for the safety and efficacy of TAVI in patients with bicuspid aortic valves (BAV), the most common congenital valve abnormality. In many TAVI(More)
The primary aim of this systematic review was to assess the efficacy of catheter ablation of atrial fibrillation (AF) in patients with hypertrophic cardiomyopathy (HCM). Differentiation based off catheter ablation modalities was not considered due to the limited scope of the current field. Studies that employed alcohol septal ablation for the treatment of(More)
OBJECTIVE The Trifecta aortic prosthesis is a latest-generation trileaflet stented pericardial valve designed for supra-annular placement in the aortic position. Robust clinical evidence and long-term follow-up data for this new prosthesis are lacking; a systematic review was conducted to assess current evidence. METHODS A comprehensive search from 6(More)
