Unusual Gastrointestinal Bleeding After Sutureless Aortic Valve Replacement: A Word of Caution.

We report the clinical case of a male patient who presented, after an aortic valve replacement with a rapid deployment bioprosthesis, a Heyde-like syndrome, secondary to a moderate aortic paravalvular leakage. All the digestive and hematologic investigations confirmed the diagnosis. A redo surgery to fill the paravalvular gap was accomplished and the postoperative course was uneventful, with a normalization of the biological parameters.

[Transient left ventricular apical ballooning or tako-tsubo syndrome: 14 cases].

Introduction: Tako-tsubo syndrome is a new diagnostic entity, still little known. Also called transient left ventricular apical ballooning, stress cardiomyopathy, and neurogenic myocardial stunning, it mimics myocardial infarction, combining chest pain with electrocardiographic changes and a moderate rise in the serum markers of necrosis. Angiography of the coronary artery is normal while that of the left ventricle shows ballooning and basal hyperkinesis.
