Primary chylopericardium.

Primary chylopericardium is a rare entity. Here we describe a 36-year-old, asymptomatic male in whom pericardial effusion was detected by chest X-ray and echocardiography on routine health control. After pericardiocentesis that revealed the chylous nature of the fluid, partial pericardiectomy without duct ligation was carried out. In the follow-up period, there was no evidence of pericardial fluid on chest X-ray and echocardiography, at three months after the procedure.

Brain natriuretic peptide and the severity of aortic regurgitation: is there any correlation?

We aimed to evaluate the correlation between aortic regurgitation severity and brain natriuretic (BNP) levels as a marker for left ventricular dysfunction. Sixty consecutive male patients (mean age 22 +/- 3 years) with isolated chronic aortic regurgitation were enrolled in the study together with a control group of 30 age-matched healthy volunteers (group A). Patients were classified with regard to aortic regurgitation vena contracta width as follows: group B, < 3 mm, mild (n = 16); group C, > or = 3 and < 6 mm, moderate (n = 26); group D, > or = 6 mm, severe (n = 18). BNP measurements were performed with a fluorescence immunoassay kit. BNP levels were increased in patients with aortic regurgitation, and severity of regurgitation had a significant influence on BNP levels. This effect can be explained by the volume loading effect of aortic regurgitation.

Donor intracranial bleeding is associated with advanced transplant coronary vasculopathy: evidence from intravascular ultrasound.

OBJECTIVES: We evaluated the impact of spontaneous intracranial bleeding (ICB) in the donor on transplant coronary vasculopathy using serial intravascular ultrasound examinations. MATERIALS AND METHODS: Between January 1995 and December 2000, 72 recipients underwent cardiac transplantation from donors who had experienced spontaneous ICB (ICB group). Their findings using serial intravascular ultrasound analysis at baseline (within 1 month) and 1 year after transplantation were compared with 90 recipients who had undergone transplantation from trauma donors (trauma group). RESULTS: Compared with the Trauma group, the ICB group showed increased coronary intimal thickness (0.55 +/- 0.33 vs 0.39 +/- 0.3 mm; P = .034), plaque volume (3.84 +/- 2.5 vs 2.28 +/- 1.65 mm(3); P = .015) and plaque burden (7.4 vs 2%) at 1 year after transplantation. CONCLUSIONS: Donor spontaneous ICB is associated with significantly increased coronary vasculopathy.

The influence of donor gender on allograft vasculopathy: evidence from intravascular ultrasound.

BACKGROUND: Allograft vasculopathy is a major risk factor for mortality following cardiac transplantation. Several immune and nonimmune factors have been evaluated as risk factors for the development of coronary vasculopathy. OBJECTIVE: We evaluated the influence of donor gender on the progression of coronary vasculopathy in heart transplant recipients. METHODS: Eighty-nine heart transplant recipients (67 men, 22 women of mean age: 56 +/- 12 years) underwent serial volumetric intravascular ultrasound analysis (IVUS) at baseline (within 1 month) and at 1 year after transplantation. Patients were divided into four groups in relation to the donor-recipient gender status: female-female, n=17; female-male, n=28; male-female, n=5; male-male, n=39. Ultrasound images were recorded during an automated pullback and with an equal number of slices (average=22 per coronary vessel). The measured IVUS indices for the left anterior descending artery were: change in maximal intimal thickness, average intimal area, total plaque volume, and intimal index. RESULTS: Patients were similar in baseline characteristics. At 1 year after transplantation, IVUS indices of coronary vasculopathy were significantly increased among recipients of female allografts (P <.05). CONCLUSION: Heart transplant recipients of female allografts display increased coronary vasculopathy progression.
