Sandwich Technique to Manage Right Ventricular Perforation During Beating Heart Coronary Artery Bypass Grafting.

Identification of an intramyocardial left anterior descending artery remains challenging and many techniques have been proposed for its identification. The exposure technique depends on the surgeon's familiarity and experience with it, and inadvertent right ventricular perforation during exposure on off-pump surgery results in bleeding, which requires urgent cardiopulmonary support and repair. Inadequate repair may result in continued bleeding, closure of the left anterior descending artery, and myocardial infarction.

Sinus venosus atrial septal defect with severe mitral stenosis: a rare variant of Lutembacher's syndrome.

Lutembacher's syndrome refers to the rare combination of congenital atrial septal defect, usually secundum type and acquired mitral stenosis. However, the presence of sinus venosus atrial septal defect along with severe mitral stenosis and severe pulmonary hypertension is rarely seen, and this article reports on this rarity with its management.

Recurrent Spontaneous Pneumomediastinum With Concurrent Pneumorrhachis: A Rare Clinical Entity.

Spontaneous pneumomediastinum is the presence of interstitial air in the mediastinal structures without an apparent cause. Pneumorrhachis is defined as the presence of air in the spinal canal. Concurrent pneumorrhachis is an extremely rare epiphenomenon of spontaneous pneumomediastinum without pneumothorax.
