The transvenous implantation of cardiac devices may sometimes cause serious complications involving the coronary arteries. The left anterior descending artery may be injured during nonapical right ventricular implantation while a right atrial lead may injure the right or circumflex coronary artery. Injury of a left internal mammary graft to a coronary artery may cause myocardial infarction.

Inadvertent anastomosis of the left internal mammary artery (LIMA) or a saphenous vein graft (SVG) to the great cardiac vein (GCV) is a rare complication of coronary artery bypass grafting (CABG). We present two cases with a LIMA to GCV and a SVG to GCV anastomosis, respectively, resulting in angina and dyspnea in the postoperative state. As an alternative to repeat CABG, both patients underwent percutaneous coronary intervention with percutaneous coil embolization or implantation of an Amplatzer vascular plug within the bypass graft to GCV conduit...

We present two cases of surgical treatment of patients with coronary artery steal syndrom and multifocal atherosclerosis, who previously underwent coronary artery bypass grafting using left internal mammary artery. In both cases carotid-subclavian bypass was performed through supraclavicular access using synthetic prosthesis. This method allowed to restore blood flow in the left internal mammary artery, eliminate recurrent angina pectoris, and improve patients quality of life. The article also contains descriptions of possible methods of surgical correction of this pathology, their advantages and disadvantages...

The deep inferior epigastric perforator flap has become increasingly popular for breast reconstruction with the most common recipient vessels being the internal mammary artery and vein. In certain cases, however, these recipient vessels are inadequate due to an absent or diminutive vein. Moreover, patients at high risk for future coronary artery disease may sacrifice the best conduit for coronary revascularization if the internal mammary recipients are used. Alternative recipient vessels, including the thoracodorsal, thoracoacromial, external jugular, and cephalic vessels have significant limitations...

Currently, there are no explicit guidelines on the management of acute myocardial infarction (MI) in young adults under the age of 30. The lack of published literature to guide clinicians in the care of young adults with MI has prompted us to report a case exemplary for the successful treatment with coronary artery bypass graft (CABG). A 25-year-old man developed acute MI and underwent on-pump five quintuple CABG using bilateral internal mammary arteries and left greater saphenous vein. This appropriate and timely intervention may have helped to prevent cardiac death and maintain the quality of life...

Harlequin syndrome is a rare autonomic disorder characterized by unilateral diminished sweating and flushing of the face in response to heat or exercise. Extrinsic ganglion compressions, most of the times by neoplasms, can induce the syndrome. During investigation of a 27 year-old woman presenting Harlequin syndrome with diminished sweating on the left side and flushing of the right half of her face, a left thyrocervical trunk aneurysm was detected by angio MRI. Thyrocervical trunk aneurysms are rare and only a few cases have been reported...

BACKGROUND: A substantial body of evidence demonstrates that myocardial revascularisation using bilateral internal mammary arteries (BIMA) improves long-term survival compared with single/left internal mammary artery (LIMA) grafting. To date, limited analyses have been made regarding other short-term and long-term outcomes in BIMA strategy. OBJECTIVES: The primary aim of the present review is to update the difference in long-term survival between BIMA and LIMA grafting and to thoroughly investigate other secondary short-term and long-term clinical outcomes between these two grafting procedures...

OBJECTIVE: Minimally invasive coronary artery bypass grafting (MICS CABG) via a small left thoracotomy is a novel technique for coronary revascularization that is increasingly used around the world. However, multivessel MICS CABG is difficult, and concerns about repeat revascularization (RR) have been raised. This longitudinal study describes the rates of RR among patients who have undergone MICS CABG and identifies targets for improvement. METHODS: A prospective observational study was performed on the 306 MICS CABG patients operated on by a single surgeon from 2005 to 2015...

We present an uncommon and underreported complication of coronary artery bypass graft surgery: erroneous anastomosis of the left internal mammary artery to the great cardiac vein. The iatrogenic aorto-coronary arteriovenous fistula with left-to-right shunting resulted in dilation of the coronary sinus, a supporting secondary finding. Factors predisposing to this inadvertent anastomosis include an intramyocardial segment of the left anterior descending coronary artery, demonstrated in this case, as well as epicardial fat and potentially fibrosis of the underlying myocardium...

Anomalous origin of the right coronary artery originating from the pulmonary trunk (ARCAPA) is a rare congenital coronary anomaly with an estimated prevalence of 0.002%. Most patients are asymptomatic and the anomaly is detected incidentally during evaluation for other problems. Occasionally, ARCAPA may lead to myocardial ischemia and/or sudden cardiac arrest. We present a case of a 55-year-old female with a history of hypertension who presented to the emergency department with intermittent chest discomfort for three days...
