BACKGROUND: To illustrate a rare cause of out-of-hospital cardiac arrest in children, its differential diagnoses, emergency and subsequent treatment at various steps in the rescue chain, and potential outcomes. CASE PRESENTATION: A 4-year-old boy with unknown agenesis of the left coronary ostium sustained out-of-hospital cardiac arrest. Bystander cardio-pulmonary resuscitation was initiated and defibrillation was performed via an automated external defibrillator (AED) shortly after paramedics arrived at the scene, restoring sinus rhythm and spontaneous circulation...

OBJECTIVE: Although the benefits of minimally invasive valvular surgery are well established, the applicability of extending these techniques to reoperative aortic valve surgery is unknown. We evaluated our experience with a minimally invasive approach to this patient population. METHODS: From January 2010 to September 2015, 21 patients underwent reoperative isolated aortic valve replacement via a minimally invasive approach by a single surgeon. All patients had preoperative evaluation with computerized tomography and coronary catheterization...

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...

BACKROUND: Coronary bypass surgery using the internal mammary artery (IMA) is among the most commonly performed procedures in treatment of advanced coronary vessel disease. Further, bilateral harvesting of the IMA is associated with increased rates of sternal wound infections. OBJECTIVE: This study aimed to explore changes in sternal perfusion, following left internal mammary artery (LIMA) harvesting. METHODS: 60 patients were divided equally into intervention- and control cohorts and underwent assessment of oxygen saturation (sO2) and relative blood flow (RBF) by laser doppler flowmetry remission spectroscopy preoperatively, 24 h and 72 h postoperatively...

Castleman's disease (CD) is a rare lympho-proliferative disorder due to faulty immune regulation resulting in proliferation of lymphatic tissue. The vascular supply to these lesions have been reported to arise from the bronchial, internal mammary and the intercostal arteries. We report a case of hemoptysis secondary to intrathoracic CD with vascular supply arising from the left inferior phrenic artery which was successfully embolised with polyvinyl alcohol (PVA) particles.

We present a patient with unstable angina candidate for coronary artery bypass grafting. Saphenous vein graft was used in obtuse marginal and left internal mammary artery to left anterior descending artery properly. After surgery, the patient experienced flaccid paralysis of lower limb and impaired sensation of touch and warmth of knee and below. A computed tomography angiogram of lower limbs and thoracolumbar magnetic resonance imaging showed no abnormality. Based on the symptom, clinical diagnosis of anterior spinal artery syndrome was considered...

The clinical benefits of using the left internal mammary artery (LIMA) to bypass the left anterior descending artery are well established making it the most frequently used conduit for coronary artery bypass surgery (CABG). Coronary subclavian steal syndrome (CSSS) occurs during left arm exertion when (1) the LIMA is used during bypass surgery and (2) there is a high grade (≥75%) left subclavian artery stenosis or occlusion proximal to the ostia of the LIMA resulting in "stealing" of the myocardial blood supply via retrograde flow up the LIMA graft to maintain left upper extremity perfusion...

Coexistence of aortic coarctation with aneurysm of subclavian artery is a uncommon situation and may require unusual treatment in patients. A 40-year-old patient diagnosed incidentally with left subclavian artery aneurysm coexisting with aortic coarctation. Patient was initially referred for hybrid treatment. Initially ostium of the left subclavian artery was covered with a stent-graft. Over a 30-month follow-up period aneurysm became thrombosed all the way up to the ostium of internal mammary artery. The patient did not present with neurological symptoms or signs of upper limb ischemia...

BACKGROUND: Saphenous vein graft thrombosis can present as unstable angina. However, percutaneous coronary intervention for saphenous vein graft lesions poses a high risk of slow flow related to the procedure. Here we present the utilization of the novel oral anticoagulant, apixaban, in the treatment of unstable angina with extensive saphenous vein graft thrombus, leading to considerable thrombus resolution and eliminating the need of percutaneous coronary intervention. CASE PRESENTATION: A 72-year-old man with 3-vessel coronary artery bypass graft surgery using a saphenous vein graft and a left internal mammary artery, performed 25 years earlier, presented at our hospital with recurrent chest tightness...

OBJECTIVE: The hemolytic product free-hemoglobin (fHb) reduces nitric oxide (NO) bioavailability. The present study aims to establish whether administration of different blood transfusions result in increased circulating fHb levels and NO consumption with effects on arterial NO-dependent blood flow in patients undergoing CABG surgery. METHODS: Ninety-five consecutive patients undergoing elective CABG surgery were prospectively divided in four groups based on blood transfusion requirements during surgery: stored blood cells (SBC, n...

OBJECTIVES: External stents significantly reduce intimal hyperplasia and improve lumen uniformity and flow pattern in saphenous vein grafts (SVG) 1 year after coronary artery bypass grafting. However, recent studies have shown that at 1 year there is a lower patency of externally stented SVG to the right coronary artery (RCA) (55-60%) when compared to the left sided coronary arteries (85-90%). In the current study, we investigated whether avoidance of both fixation of the external stent to the anastomoses and the use of metal clips to ligate SVG side branches would improve the early patency of externally stented SVG to the RCA...

Intrathoracic neurofibromas are relatively uncommon in patients with neurofibromatosis. They are usually asymptomatic and may be discovered incidentally. We present the case of a 51-year-old, African American man with neurofibromatosis type 1 who underwent coronary revascularization. Intraoperatively, numerous neurofibromas were discovered, one of which was attached to the left internal mammary artery. The procedure was uncomplicated despite the challenging intraoperative findings. Special considerations in the management of patients with neurofibromatosis undergoing cardiac surgery are discussed, including risks, preoperative imaging and the importance of excision of suspicious tumors...

Background Proper treatment of patients with diffuse, severe coronary artery disease (CAD) is a challenge due to its complexity. Thus, data on the outcomes after coronary artery bypass graft (CABG) in this population is scarce. In this study, we aimed to determine the impact of CABG on the clinical and functional status, as well as graft patency in those individuals. Methods Patients with severe and diffuse CAD who underwent incomplete CABG due to complex anatomy or extensive distal coronary involvement were evaluated preoperatively and 1 year after surgery...

True aneurysms of the internal mammary artery are rare and have been described in association with vasculitis or connective tissue disorders. Herein, we describe 2 cases of familial internal mammary artery aneurysms (IMAs) in 2 sisters with SMAD3 mutation. The older sister presented at the age of 54 years with an incidental diagnosis of a multilobed right IMA and the younger sister presented several years earlier with a ruptured left IMA aneurysm at the age of 49 years. Both sisters had Debakey type I aortic dissections prior to the IMA aneurysm presentation...
