Comparative StudyCardiac troponin I as diagnostic and prognostic marker in severe heart failure.
Cardiac cell death has been shown to occur in heart failure and has been implicated as one of the mechanisms responsible for progression of the disease. Cardiac Troponin I (cTnI) represents a highly sensitive marker for myocardial cell death. Based on previous studies reporting that cTnI may be detected in patients with heart failure, we evaluated the clinical correlates and prognostic implications of detectable cTnI in a consecutive series of patients with severe heart failure. ⋯ These observations suggest that cTnI is detected in the blood of 25% to 33% of patients with severe heart failure; its presence may help to identify a high-risk sub-group who faces very poor short-term prognosis.

Case ReportsBalloon-expandable stent placement for superior vena cava-right atrial stenosis after heart transplantation.
Anastomotic Stenoses are well known as a complication of vascular and cardiovascular surgical procedures; such a lesion was encountered at the superior vena cava-right atrial anastomosis after cardiac transplantation. A balloon expandable stent was used to relieve this anastomotic constriction, employing a 16 mm diameter balloon to deliver a P304 stent. Stent placement resulted in complete relief of the patient's symptoms and facilitated the passage of bioptomes through the superior vena cava for subsequent biopsy procedures following cardiac transplantation.
