We have read with great interest the case presentation entitled 'Successful Right Ventricular Tachycardia Ablation in a Patient with Left Ventricular Non-compaction Cardiomyopathy' by Honarbakhsh et al. in the recent issue of the journal [1]. They successfully ablated an arrhythmia focus originated from the normally appearing right ventricular free wall using the three-dimensional mapping and r...

BACKGROUND Patients with atherosclerotic renovascular disease (ARVD) are almost invariably treated by revascularization. However, the long-term outcomes of this approach on survival and progression to renal failure have not been investigated and have not been compared with that of a purely medical treatment. The aim of this observational study was to investigate factors affecting long-term (ove...

BACKGROUND Renal impairment is common in patients with atherosclerotic renovascular disease (ARVD), but its pathogenesis is uncertain. This study investigated whether any relationship existed between renal function and the severity of proximal renal arterial lesions in patients with ARVD. METHODS A cohort of 71 patients had creatinine clearance measured at the time of digital subtraction angi...

BACKGROUND/AIMS Optimized medical therapy has improved cardiovascular outcomes in the general population. To investigate whether changes in the management of atherosclerotic renovascular disease (ARVD) have had an impact on clinical outcomes. METHODS Recruitment into this single-center prospective cohort study started in 1986. Data was analyzed retrospectively. Patients were divided into four...

Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is a congenital cardiac disease with myocardial involvement, most probably right ventricular (RV) dysfunction, accounting for 20% of sudden cardiac deaths. Characterized by the fibro-fatty infiltration of the RV free wall, ARVD/C presents in adolescents with ventricular arrhythmias and heart failure symptoms and as biventricular...

With an increasingly ageing and atherosclerotic-prone population, clinical encounters with patients with atheromatous renovascular disease (ARVD) are commonplace. ARVD is frequently associated with chronic kidney disease (CKD) and hypertension, but evidence suggests that causality only occurs in the minority and it is likely that many atherosclerotic renal artery stenosis (RAS) lesions are inci...

OBJECTIVE Atherosclerotic renovascular disease (ARVD) aggravates renal scarring more than other causes of renal artery stenosis (RAS), but the underlying pathogenic mechanisms of this potential profibrotic effect remain unclear. We tested the hypothesis that coexistence of atherosclerosis and RAS interferes with renal tissue remodeling. METHODS AND RESULTS Single-kidney hemodynamics and funct...

Background Guidelines are an important vehicle in the era of evidence-based medicine and diagnosis. They represent a culmination of expert opinions and the best available evidence. There can be a tendency for practitioners to view and apply guidelines as the absolute truth. However, it is important to remember that guidelines are only as robust as the strength of the studies that are used in th...

Ventricular arrhythmias due to ARVD and right ventricular outflow tract arrhythmia (RVOTA) share the same left bundle branch block pattern with inferior axis on the ECG. The former has a more malignant course while the latter has a better prognosis and is more amenable to radiofrequency catheter ablation. Hence differentiating them is of utmost clinical importance in the management of these pat...
