Although the benefits of using the left internal mammary artery to bypass the left anterior descending artery (LAD) have been extensively ascertained, freedom from major cardiovascular events and survival after coronary artery bypass grafting (CABG) also correlate with the completeness of revascularisation. Hence, careful selection of the second-best graft conduit is crucial for CABG success. The more widespread use of saphenous vein grafts contrasts with the well-known long-term efficacy of multiple arterial grafting, which struggles to emerge as the procedure of choice due to concerns over increased technical difficulties and higher risk of postoperative complications...

Breast cancer is a common diagnosis in women and thus women are at risk of radiation-induced heart disease, in particular during radiotherapy for left breast cancer and when the internal mammary chain is included. Rates of major cardiac events increase with younger age at the time of irradiation, diagnosis before 1990s, higher radiation doses, coexisting cardiovascular risk factors and adjuvant cardiotoxic chemotherapy. Radiation-induced heart disease comprises a spectrum of cardiac pathologies, including pericardial disease, cardiomyopathy, coronary artery disease and valvular disease...

OBJECTIVE: The clinical significance of unligated major left internal mammary artery (LIMA)-side branches (SB) remains controversial in patients with previous coronary artery bypass graft (CABG) surgery. The aim of this study was to investigate the clinical significance of unligated major LIMA-SB by using exercise myocardial perfusion imaging (MPI) with single-photon emission tomography. SUBJECTS AND METHODS: We conducted a retrospective analysis of 2819 consecutive patients who underwent diagnostic angiography...

AIM: Coronary artery bypass graft surgery is the gold standard for the treatment of multi-vessel and left main coronary artery disease. However, there is considerable debate that whether left internal mammary artery (IMA) should be taken as pedicled or skeletonized. This study was conducted to assess the difference in blood flow after application of topical vasodilator in skeletonized and pedicled IMA. METHODS: In this study, each patient underwent either skeletonized (n=25) or pedicled IMA harvesting (n=25)...

BACKGROUND: Coronary artery perforation associated to cardiac tamponade is an uncommon life-threatening complication of percutaneous coronary intervention, and the occurrence of subepicardial or intramyocardial hematoma without hemopericardium is even rarer. CLINICAL CASE: We describe the case of a 72 year-old woman with a subepicardial hematoma after percutaneous coronary intervention, who required urgent left internal mammary artery graft to anterior descending artery surgery...

A 64 years old male diabetic patient with ejection fraction of 16% and renal dysfunction underwent off-pump CABG using both in situ internal mammary artery grafts. Left internal mammary artery was used to bypass left anterior descending artery and right internal mammary artery was used as composite graft. Patient had uneventful recovery and left ventricular ejection fraction improved to 34% within 8 months after surgery. In presence of left ventricular dysfunction, both internal thoracic artery grafting should be preferred for better patency rate and flow reserve...

The metabolically active endothelium of arterial grafts is reported to slow the atherosclerotic process in the distal coronary territories to which they are grafted with improved patency. The literature on arterial grafting causing proximal plaque regression is scant. We report here a case of proximal left anterior descending artery (LAD) plaque regression following distal arterial grafting with a left internal mammary arterial (LIMA) graft to LAD. This rarely documented regression resulted in "stringing" of the arterial graft, while there was a significant progression of atherosclerotic disease in the right coronary with patent venous graft and de novo lesion in circumflex territory necessitating percutaneous coronary intervention, in spite of aggressive medical therapy...

A hybrid strategy, firstly performed in the 1990s, is a combination of tools available only in the catheterization laboratory with those available only in the operating room in order to minimize surgical morbidity and face with any cardiovascular lesion. The continuous evolution of stent technology along with the adoption of minimally invasive surgical approaches, make hybrid approaches an attractive alternative to standard surgical or transcatheter techniques for any given set of cardiovascular lesions. Examples include hybrid coronary revascularization, when an open surgical anastomosis of the left internal mammary artery to the left anterior descending coronary artery is performed along with stent implantation in non-left anterior descending coronary vessels, open heart valve surgery combined with percutaneous coronary interventions to coronary lesions, hybrid aortic arch debranching combined with endovascular grafting for thoracic aortic aneurysms, hybrid endocardial and epicardial atrial fibrillation procedures, and carotid artery stenting along with coronary artery bypass grafting...

Our goal is to introduce a new hybrid coronary revascularization concept-coronary surgical stenting. The procedure was performed on a 78-year old woman with severe, long and calcified involvement of the proximal left anterior descending artery, chronic total occlusion of the mid-left anterior descending artery and severe disease in the distal left anterior descending artery. An off-pump minimally invasive procedure was performed through the fifth intercostal space, including concurrent surgical placement of a drug-eluting stent in the distal left anterior descending artery, through the left anterior descending artery graft incision, associated with the left internal mammary artery to the mid-left anterior descending artery graft...

Delayed cardiac tamponade after a penetrating chest injury is a rare complication. The clinical diagnosis of tamponade is facilitated with imaging. We present a case report of a 23-year-old male who was brought to emergency after multiple stab wounds to the chest. After resuscitation and repair of laceration of right internal mammary artery and right ventricle, he was discharged but later returned with shortness of breath. Echocardiography revealed a rare case of delayed pericardial tamponade causing left ventricular collapse...

A 2-month-old male with dysmorphic facies, neonatal thrombocytopenia, left congenital cataract, and long bone abnormalities became hypotensive with ST depression on induction of anesthesia for congenital cataract repair. Echocardiogram demonstrated decreased left ventricular function (ejection fraction 46%), mild mitral valve regurgitation (MR), and regional wall motion abnormalities. The left coronary artery could not be visualized. Subsequent cardiac catheterization confirmed atresia of the left main coronary artery...

BACKGROUND: Despite the proven advantages of total arterial grafting in patients undergoing coronary artery bypass operation, its benefits in the elderly population at long-term follow-up have been widely debated to date. METHODS: Among 988 consecutive patients scheduled to undergo coronary artery bypass grafting operation, we performed a propensity-matched analysis in a population with double and triple vessel disease and older than 70 years and compared patients receiving total arterial grafting (G1; n = 315 patients) with conventional myocardial revascularization (left internal mammary artery on left anterior descending coronary artery plus saphenous vein grafts; G2; n = 201 patients)...
