Myocardial revascularization through a gastric pedicle

Endogenous myocardial angiogenesis and revascularization using a gastric submucosal patch.

BACKGROUND The gastrointestinal submucosa physiologically produces angiogenic proteins. We examined whether these properties could lead to endogenous myocardial angiogenesis in a swine model of chronic ischemia. METHODS Fifteen Yorkshire swine underwent ameroid constrictor placement around the circumflex artery and either lateral epicardial abrasion, creation of a gastroepiploic artery (GEA) ...

Myocardial revascularization and ventricular restoration through pacopexy.

OBJECTIVE To analyze left ventricle performance after myocardial revascularization associated to ventricular geometrics restoration by "pacopexy" in schemic myocardiopathy patients with significant ventricular dysfunction in whom ventricular restoration was obtained through special technique. METHODS Myocardial revascularization associated to ventricular geometrics restoration through special...

Myocardial revascularization through a mini-thoracotomy with thoracoscopic assistance.

OBJECTIVE Left internal mammary artery harvesting through a mini-thoracotomy makes gaining the proximal portion of this vessel very difficult and exposes the patient to the risk of chest wall trauma due to excessive spreading of the ribs. The adoption of video thoracoscopic assistance can give several advantages to the procedure. METHODS With the patient in a 30 degrees left-side-up thoracoto...

Myocardial revascularization.

Myocardial laser revascularization.

Some patients with severe angina have coronary artery disease which is unsuitable for conventional forms of revascularization — coronary angioplasty/ stenting or coronary artery bypass surgery. These patients have usually undergone previous revascularization procedures and have disease which is diffuse and affects the distal part of the coronary circulation. Transmyocardial laser revascularizat...
