INTRODUCTION: Coronary artery bypass graft (CABG) surgery remains the gold standard in the treatment of multivessel coronary disease. Several studies have shown that CABG with bilateral internal mammary arteries (BIMA) has better results in long-term survival. METHODOLOGY: We conducted a retrospective investigation in CABG surgeries with BIMA, performed from January 2012 to December 2015 in the National Cardiovascular Institute, INCOR, EsSalud. The objectives were determine the mortality and major cardiovascular events at 30 days follow up...

OBJECTIVES: This study evaluates reinterventions for degenerated stentless aortic xenografts. METHODS: Between 2010 and 2015, 52 consecutive patients (age 72.3 ± 9.7 years, EuroSCORE II 11.1 ± 8.9%) underwent reintervention for failed stentless aortic valves (60% porcine, 40% pericardial, 87% sub-coronary, 81% isolated/combined regurgitation). RESULTS: Based on age, EuroSCORE II, the presence of pulmonary hypertension, renal failure, a patent internal mammary artery graft and required concomitant procedures, the heart team assigned 25 patients to reoperation and 27 to valve-in-valve transcatheter aortic valve implantation (ViV-TAVI)...

OBJECTIVE: Sclerostin (SOST) has been identified as an important regulator of bone formation; however, it has not been previously implicated in arterial disease. The aim of this study was to assess the role of SOST in aortic aneurysm (AA) and atherosclerosis using human samples, a mouse model, and in vitro investigations. APPROACH AND RESULTS: SOST protein was downregulated in human and mouse AA samples compared with controls. Transgenic introduction of human SOST in apolipoprotein E-deficient (ApoE(-/-)) mice (SOST(Tg)...

The objectives of the present study were to design a method to estimate mammary plasma flow (MPF) in lactating sows using downstream dilution of -aminohippuric acid (AH) and to compare these estimates with MPF estimates based on specific AA as internal markers (MPF-AA). A permanent indwelling catheter was surgically implanted in the femoral artery, and another 2 were inserted in the right cranial mammary vein of 8 second- and third-parity sows on d 76 ± 2 SEM of gestation. On the 3rd and 17th days in milk, arterial and venous blood samples were drawn in hourly intervals from 0...

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%)...

Deep inferior epigastric artery perforator (DIEP) flaps have become an attractive option for autologous breast reconstruction. The internal mammary artery (IMA) is the usual artery of choice for reconstruction. Unfortunately, there are certain situations when the IMA may not be suitable for usage as in previous radiation or diminutive size. Several options have been documented, such as using the thoracodorsal vessels. In this case report, we report usage of the distal and proximal ends of a contralateral single mammary artery to supply antegrade and retrograde flow to bilateral DIEP flaps...

Marfan syndrome (MFS) is an autosomal dominant condition that is caused by abnormal synthesis of connective tissue. The syndrome classically affects the ocular, musculoskeletal, and cardiovascular systems. The most common cardiovascular manifestations include mitral valve prolapse/regurgitation and aortic aneurysms at high risk of rupture and dissection. However, internal mammary artery (IMA) true aneurysms are rarely reported. In this case report, we describe a 43-year-old male patient with MFS and three previous thoracotomies referred for endovascular repair of bilateral IMA true aneurysms...

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...

BACKGROUND: Autologous abdominal tissue transfer is a well-established method of breast reconstruction. The deep inferior epigastric perforator (DIEP) flap has the additional benefit of minimal donor site morbidity as it spares the muscle and fascia. Conventional DIEP flaps may not provide adequate volume in cases where the patient is thin, has midline abdominal scars, and/or has a large volume of tissue to replace. One solution is to use a bipedicled DIEP flap, incorporating all the available abdominal tissue...

The 25 bitter taste receptors (T2Rs) in humans perform a chemosensory function. However, very little is known about the level of expression of these receptors in different tissues. In this study, using nCounter gene expression we analyzed the expression patterns of human TAS2R transcripts in cystic fibrosis bronchial epithelial (CuFi-1), normal bronchial epithelial (NuLi-1), airway smooth muscle (ASM), pulmonary artery smooth muscle (PASM), mammary epithelial, and breast cancer cells. Our results suggest a specific pattern of TAS2R expression with TAS2R3, 4, 5, 10, 13, 19, and 50 transcripts expressed at moderate levels and TAS2R14 and TAS2R20 (or TASR49) at high levels in the various tissues analyzed...

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...

PURPOSE: Taking into consideration that the aberrant right subclavian artery (ARSA) is the commonest congenital aortic arch anomaly (prevalence 0.16-4.4%), our goal was to investigate its incidence in Greeks, with respect to location, course, and relationship to trachea and esophagus. Gender dimorphism, coexisting neural, and vascular variations were also examined. The clinical impact and embryological background of the variation are discussed. METHODS: Two hundred and sixty-seven (126 male and 141 female) formalin-embalmed Greek cadavers (mean age 59 ± 13 years) were examined...

OBJECTIVES: Transaxillary approach to first rib resection and scalenectomy (TAFRRS) is a well-established technique for treatment of thoracic outlet syndrome (TOS). Although anatomic features encountered during TAFRRS are in general constant, vascular anomalies may be encountered but have not been described to date. Herein we describe vascular abnormalities encountered during TAFRRS. METHODS: We performed a retrospective review of a prospective practice database of 224 operations for TOS performed in 172 patients from 3/2000 to 3/2014...

Background The use of bilateral internal thoracic (mammary) arteries for coronary-artery bypass grafting (CABG) may improve long-term outcomes as compared with the use of a single internal-thoracic-artery plus vein grafts. Methods We randomly assigned patients scheduled for CABG to undergo single or bilateral internal-thoracic-artery grafting in 28 cardiac surgical centers in seven countries. The primary outcome was death from any cause at 10 years. The composite of death from any cause, myocardial infarction, or stroke was a secondary outcome...

BACKGROUND: Robotic-assisted coronary artery bypass graft surgery (CABG) has been performed over the past decade. Despite encouraging results from selected centres, there is a paucity of robust clinical data to establish its clinical safety and efficacy. The present systematic review aimed to identify all relevant clinical data on robotic CABG. The primary endpoint was perioperative mortality, and secondary endpoints included perioperative morbidities, anastomotic complications, and long-term survival...

BACKGROUND: Glycated hemoglobin (HbA1c) is a suspected risk factor for sternal wound infection (SWI) after CABG.Methods and Results:Data on preoperative HbA1c and SWI were available in 2,130 patients undergoing isolated CABG from the prospective E-CABG registry. SWI occurred in 114 (5.4%). Baseline HbA1c was significantly higher in patients with SWI (mean, 54±17 vs. 45±13 mmol/mol, P<0.0001). This difference was also observed in patients without a diagnosis of diabetes (P=0.027), in insulin-dependent diabetic (P=0...

Internal mammary artery (IMA)-based pedicled perforator flaps can be used to reconstruct defects of the neck and anterior chest wall. Pre-expansion causes a possible delay phenomenon, improves flap survival, and decreases donor site morbidity. It also increases the area that can be covered. Pre-expanding can allow for perforator flaps that require a shorter arc of rotation. The pre-expanded internal mammary artery perforator (IMAP) flap is an excellent option for patients who have undergone multiple failed reconstructions and require large amounts of soft tissue while lacking other donor sites...
