BACKGROUND The AVERT(TM) Contrast Modulation System (AVERT) (Osprey Medical, MN) is designed to reduce contrast volume administration during angiography. The AVERT provides an adjustable resistance circuit which decreases the pressure head delivering contrast towards the patient. The AVERT has not been previously studied in patients undergoing peripheral(More)
Takotsubo cardiomyopathy (TTC) was first described in 1990 in a Japanese text1 as a reversible form of left ventricular dysfunction, followed up by a case series in five patients. Although previously considered rare, over the past two decades there has been a marked rise in the number of publications relating to TTC, with the current estimation being that(More)
PURPOSE The purpose of this article was to review the clinical management of patients with heart failure with preserved ejection fraction (HFPEF). METHODS For this critical review, electronic databases (MEDLINE, EMBASE, PubMed) were searched for relevant basic research studies and randomized clinical trials recently published or presented at major(More)
A highly complex interplay exists between the heart and kidney in the setting of both normal and abnormal physiology. In the context of heart failure, a pathophysiological condition termed the cardiorenal syndrome (CRS) exists whereby dysfunction in the heart or kidney can accelerate pathology in the other organ. The mechanisms that underpin CRS are(More)

SETTING Clinic for patients referred or admitted to the University Medical Unit, National Hospital of Sri Lanka, Colombo,(More)
Mechanical circulatory support using left ventricular assist devices (LVADs) has been demonstrated to improve survival in patients with advanced heart failure. Left ventricular assist device therapy also promotes reverse ventricular remodeling, which in some cases has led to sufficient myocardial recovery to allow LVAD removal. Identification of suitable(More)
