The Secret behind Extreme Hypoxia Tolerance: A "Slow-Growth" Thoracoabdominal Aneurysm.

A 61-year-old man presented to our institution complaining of back pain. Breathing was comfortable. An arterial blood gas showed extreme hypoxia causing chronic respiratory alkalosis.

Reoperation after surgical correction of acute type A aortic dissection: risk factor analysis.

Background: Aortic dissection is an evolving process that may require one or several reoperations after its initial repair. We conducted a study to evaluate risk factors and define the incidence and locations of reoperations after surgical correction of acute type A aortic dissection (AAD).

Methods: Between 1998 and 2008, 250 consecutive patients (mean age 62.

Tako-tsubo syndrome: a potential role for cytomegalovirus infection.

The tako-tsubo syndrome is a transient cardiomyopathy of unknown origin, which mimics acute ST-elevation myocardial infarction in the absence of obstructive epicardial coronary artery disease. This novel syndrome is characterized by chest pain, ST-segment changes, minimal enzymatic release, and balloon-like asynergy of the apical region. We report a case of tako-tsubo syndrome associated with acute cytomegalovirus infection and discuss the possible role of a viral aetiology in the onset of this syndrome.

Myocardial bridging in hypertrophic cardiomyopathy: a plea for surgical correction.

Myocardial bridging may be associated with an unfavorable prognosis in patients with hypertrophic cardiomyopathy. We describe a case of a young symptomatic patient with myocardial bridging associated with hypertrophic cardiomyopathy successfully treated by surgical unroofing. Such a procedure should be strongly recommended in patients with hypertrophic cardiomyopathy.

Occluding clamp technique during coronary artery bypass grafting: single or double-clamp technique?

Background: External manipulation of the diseased aorta during cardiac surgery is the most important mechanism leading to the detachment of atherosclerotic debris due, especially, to the use of aortic clamping. The aim of the present study was to determine the best occluding clamp technique to minimize the risk of postoperative cerebrovascular accidents in patients who undergo isolated coronary artery bypass grafting (CABG): single-clamp technique (SCT) or double-clamp technique (DCT)?

Methods: Two hundred and eighty-one consecutive patients undergoing isolated CABG in our center between January 2001 and December 2003 were enrolled. SCT was used in 145 cases and DCT was used in 136 cases.
