Postoperative aortobronchial and aortopulmonary fistulas are rare and late complications of cardiac surgery. They mostly complicate descending thoracic aortic procedures. Hemoptysis is the main symptom, and may be massive or intermittent. The reported interval between the time of operation and the onset of hemoptysis ranges from 3 weeks to 25 years.(More)
BACKGROUND AND AIM The internal thoracic artery (ITA) has a better long-term patency than saphenous veins, and anastomosis between ITA and the left anterior descending artery (LAD) represents the "gold-standard" of surgical myocardial revascularization. The aim of this study is to evaluate the multidetector multislice CT Scan (MCTS) as a means of(More)
This clinical feasibility study was planned to evaluate pericardioscopy as a means of control of the pericardial cavity during drainage for pericardial effusion by a surgical sub xyphoid approach. Seventeen patients who underwent an operation for surgical drainage of the pericardium (11 medical and 6 postoperative pericardial effusions) benefited from a(More)
INTRODUCTION It has been proven that blood supply to the heart can include blood from noncoronary collateral circulation. Whether this network can somehow be augmented to provide an alternative therapy for ischemic patients is an intriguing hypothesis with no clear answer yet due to the challenging nature of this research field. In an attempt to enhance(More)
Non-coronary collateral blood flow arrives to the heart from mediastinal, bronchial, and pericardial channels. These enter the heart through the pericardial reflections surrounding the pulmonary and systemic veins, as well as from the vasa vasorum of the aorta and the pulmonary artery leading to and from the myocardium. Before the advent of cardiopulmonary(More)
Intramural left atrial dissection and hematoma as a complication of a coronary stenting procedure is a very rare entity. We report the case of a 73-year-old man who underwent percutaneous coronary angioplasty for a severe stenosis of the left circumflex coronary artery, complicated by a left atrial intramural hematoma, and was successfully treated with via(More)
BACKGROUND Reinfusion of shed blood after coronary artery bypass grafting might increase the levels of cardiac enzymes with consequent difficulties in the diagnosis of perioperative myocardial infarction. METHODS Thirty consecutive patients undergoing coronary artery bypass grafting who bled at least 400 mL within the first 4 hours after operation(More)
The internal thoracic arteries (ITAs) are a source of "noncoronary collateral circulation" (NCCC), or "noncoronary collateral blood flow" (NCCBF). The hypothesis herein is that enhancement of NCCC may represent an alternative means of myocardial blood supply: (1) Ligature of the ITAs creates a local hypertensive status and increases the perfusion pressure(More)
