AIM OF THE STUDY: Coronary artery bypass graft surgery is the gold standard for the treatment of multivessel 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 the application of topical vasodilator in skeletonized and pedicled IMA. MATERIALS AND METHODS: In this study, each patient underwent either skeletonized (n = 25) or pedicled IMA harvesting (n = 25)...

In patients with history of coronary artery disease angina pectoris is usually attributed to the progression of atherosclerotic lesions. However, in patients with previous coronary artery bypass graft operation (CABG) using internal mammary artery grafts, great vessel disease should also be considered. Herein we present two patients with history of CABG whose symptoms were suspicious for coronary ischemia. During cardiac catheterization reverse blood flow was observed from the left artery disease to the left internal mammary artery (LIMA) graft in both cases...

BACKGROUND: During coronary artery bypass grafting (CABG), the ratio of powers of the fundamental frequency and its first harmonic (F0/H1) in fast Fourier transformation (FFT) analysis of the graft's flow waves has been used in the field of evaluation of the patency in anastomosis. But there is no report about using the FFT method to evaluate the magnitude of competitive flow. This study is aiming at exploring the relationship between competitive flow and FFT analysis of the flow waves in left internal mammary artery (LIMA) graft, and finding a new method to evaluate the magnitude of competitive flow...

PURPOSE: The purpose of this study was to evaluate the impact of the active breathing control (ABC) technique on IMN coverage and organs at risk in patients planned for postmastectomy radiation therapy (PMRT), with the inclusion of the internal mammary lymph nodes (IMNs). The effect of body mass index (BMI) on recorded dosimetric parameters was examined in the same patient cohort. METHODS AND MATERIALS: Fifty left-sided postmastectomy patients with breast cancer who underwent free-breathing (FB) and ABC-Elekta CT simulation scans were selected at random from an institutional breast cancer database between 2008 and 2014...

Since the 1990s, a large body of literature has been published regarding minimally invasive coronary artery bypass grafting. Varying techniques, complexity of the procedures and the necessity of patient selection have led to its inconsistent application. We describe the standardized technique of left internal mammary artery grafting to the left anterior descending coronary artery, off-pump through a left inferior J-hemisternotomy (JOPCAB). This approach is straightforward, safe, effective, and replicable in virtually all patients...

OBJECTIVE: Although video-assisted thoracic surgery (VATS) lobectomy has become a standard approach for early-stage 1 lung cancer, concerns exist regarding potential damage to the heart or bypass grafts when VATS is performed after cardiac surgery via median sternotomy. We could find only case reports regarding VATS lobectomy after sternotomy for cardiac surgery. Therefore, we reviewed our series of patients who underwent VATS anatomic resections after sternotomy for cardiac surgery. METHODS: Between 1996 and 2010, there were 87 patients who underwent 88 pulmonary resections after sternotomy for coronary artery bypass grafting (64), valve replacement or repair (12), coronary artery bypass graft and valve replacement (6), and transplant (5)...

OBJECTIVE: Benefits of adding a second arterial graft in coronary bypass are well documented. In patients requiring mulitvessel grafting robotic totally endoscopic coronary bypass (TECAB) has allowed for routine harvesting and use of the right internal mammary artery (RIMA). We retrospectively reviewed the technical considerations and target choice in 140 cases of beating heart TECAB where a RIMA graft was used. METHODS: In 2008, we introduced beating heart TECAB with anastomotic connectors into our practice, first with single IMA and then with bilateral internal mammary artery...

There are limited contemporary studies comparing coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) for isolated proximal left anterior descending (LAD) disease. Increasing stent length and decreasing stent diameters are associated with increased risk of restenosis and adverse outcomes after PCI. Whether these parameters influence outcomes when comparing CABG and PCI is unclear. We compared CABG and PCI in 3,473 patients who underwent revascularization for isolated proximal LAD disease from 2004 to 2015 at Harefield Hospital, UK; 3,078 patients (89%) had PCI and 384 patients had CABG (11%)...

Coronary-subclavian artery (SCA) steal syndrome is an uncommon phenomenon in which coronary flow is diverted into the SCA through the patent left internal mammary artery (LIMA) conduit due to critical subclavian stenosis. The prevalence of significant left SCA (LSCA) stenosis in patients, referred for coronary bypass surgery, has been reported to be 0.2 to 6.8%. Most patients usually present with angina pectoris, and secondary myocardial infarction is rarely reported. Herein, we present a case of coronary bypass graft in which a left anterior descending artery-LIMA graft was applied to supply the left arm due to complete LSCA occlusion...

Anomalous origin of the right coronary artery (ARCA) from the left Valsalva sinus is a rare but known cause of sudden cardiac death. Surgical revascularization techniques include coronary artery bypass grafting, unroofing, and reimplantation. We report 4 patients who underwent robot-assisted totally endoscopic coronary artery bypass (TECAB) for ARCA as an alternative surgical option. In 3 patients, a single aortocoronary saphenous vein bypass was performed, and in 1 patient the right internal mammary artery was used...

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...

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...
