Prostaglandin E1 (PGE1) infusion was used in 7 infants with hypoplastic left ventricle and aortic atresia. Of 5 non-operated patients, 4 died shortly after the onset of PGE1 infusion and 1 survived for 30 hours. Of the infants who had surgery, 1 died during the operation and 1 survived for 38 days. In 6 infants, a transient metabolic and/or circulatory improvement could be demonstrated following PGE1 infusion. The lack of response of other infants may be related to the advanced deterioration of their clinical status at the time of study. In the light of recent surgical developments for infants with aortic atresia, support with PGE1 may nevertheless play an important role in their management if started early.

Left Main Coronary Artery Ostial Stenosis Caused by Syphilitic Aortitis Presenting With Syncope.
JACC Case Rep

Department of Cardiovascular Medicine, Kobe City Medical Center General Hospital, Kobe, Japan.
A 51-year-old man with a history of antibiotic therapy for syphilis 1 month ago presented with syncope. Computed tomography revealed circumferential aortic wall thickening complicating severe stenosis of left main coronary ostium. Abnormalities in serologic and cerebrospinal fluid tests led to the diagnosis of syphilitic aortitis and neurosyphilis.

With the advancement in imaging technology, ECG-gated cardiac multidetector computed tomography (MDCT) has emerged as a tool for the anatomic evaluation of the pulmonary valve and right ventricular outflow tract (RVOT) in human medicine. Currently, the evaluation of the pulmonary valve relies primarily on echocardiographic examination. However, the bi-dimensional nature of this technique and the location/orientation of the pulmonary valve in the thoracic cavity can pose challenges.

Department of Geriatrics, Medical Center on Aging of Shanghai Ruijin Hospital, Shanghai Jiaotong University School of Medicine, Shanghai, China.
The aim of this study was to explore whether 24-h ambulatory central (aortic) blood pressure (BP) has an advantage over office central aortic BP in screening for hypertension-mediated target organ damage (HMOD). A total of 714 inpatients with primary hypertension and the presence of several cardiovascular risk factors or complications involving clinical HMOD were enrolled. Twenty-four hour central aortic BP was measured by means of a noninvasive automated oscillometric device (Mobil-O-Graph).

Background: Coarctation of the aorta (CoA) is a narrowing of the aorta that affects 5-8% of congenital heart defects. Treatment options include surgical repair or transcatheter management with endovascular stenting or balloon dilatation. Late complications after operative repair include systemic hypertension, aortic valve abnormalities, aortic aneurysm, and recoarctation.

A short cut review of the literature was carried out to examine whether a decision rule in conjunction with a D-dimer can be used to rule out aortic dissection. 117 unique papers were found of which three systematic reviews included data on patients relevant to the clinical question; these are discussed in the paper. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of the best papers are tabulated.
