RF06 THE CHOICE OF THE BEST PROSTHETIC VALVE IN CARDIAC OCHRONOSIS
Authors: Barbato L. , Musso P. , Baronetto A. , Trimboli S. , Casabona R. , Marra S. , Comoglio C. Dr ssa 
Published: November 2018

Background:
Alkaptonuria is a rare autosomal genetic anomaly of the metabolism of tyrosine, and is characterized by the accumulation of homogentisic acid in the extracellular matrix with destruction of numerous tissues. Ocronosis is rarely associated with abnormalities of the cardiovascular system. The most common clinical manifestation is aortic valve stenosis. There is no specific therapy for alkaptonuria, limiting itself to the treatment of only the complications of the pathology.

Methods:
We report the case of a 69-year-old patient diagnosed with ochronosis following the detection of skin and scleral pigmentations. The patient was sent to our center with indication to replace the aortic valve for severe aortic stenosis after syncope episode.

Results:
Surgical intervention, the opening of the aorta, it is detected an abnormal blue-black pigmentation intima of the ascending aorta and aortic root with across where the flaps of the aortic valve and the anterior leaflet of the mitral valve. The aortic valve was replaced with a biological prosthesis No. 19. At follow up to twelve months, the patient is asymptomatic, at echocardiographic control the prosthetic valve appears normally functioning without signs of degeneration.
The surgical technique of aortic valve replacement is not different in these patients, but the choice of the best prosthetic valve in cardiac ochronosis is still a matter of debate. In fact, the problem still remains discussed the possible deposition of the blue-black pigment at the level of biological prosthesis with its rapid deterioration. Our preliminary observations must naturally be confirmed by carefully conducted prospective studies.

Authors: Nicolo’ F. , Cagnoni G. , Guerciotti B. , Vergara C. , Ippolito S. , Quarteroni A. , Antona C. , Scrofani R. 
Published: November 2018

Background and Aim:
Arterial or venous conduits used for Y-graft have different outcomes in terms of risk of restenosis and subsequent graft failure in coronary artery bypass grafting (CABG). The aim of the study was to investigate how the choice of the graft conduit predicts the risk of graft failure.

Methods:
We performed a computational fluid dynamics numerical simulation (FSI) analysis to describe the blood flow in the coronary arteries and grafts. Different Y-grafts with radial artery (RA) or saphenous vein (SV) were investigated by changing their mechanical properties (Young's modulus) and geometric characteristics. Coronary artery stenosis degree was also virtually varied, to assess the fluid behaviour in relation to the severity of the stenosis. Relative Residence Time (RRT) and Von Mises (VM) stresses were used as indicators of disturbed fluid-dynamic and for the analysis of the wall mechanics, respectively.

Results:
A more disturbed fluid-dynamic was observed for lower stenosis degree. Retrograde flow was present in the RA graft for the 50% and 70% stenosis degree. RRT values were higher in lower stenosis degree and both grafts. RRT and VM stresses were higher for the SV graft.

Conclusions:
Venous Y-graft is characterized by a more disturbed flow at the anastomosis site with a higher vessel's wall shear stress compared to the arterial one. Because of the potentially negative effects of competitive flow in low-grade native coronary artery stenosis, we confirm the better long-term patency in arterial CABG for critical coronary stenosis.
RF85 THE ROLE OF NEW-ONSET ATRIAL FIBRILLATION AFTER CORONARY ARTERY BYPASS GRAFT SURGERY ON PATIENTS OUTCOMES: THE REAL CLINICAL IMPACT.
Authors: CUKO E. , SBAFFI A. , SCARPARI C. , PELENGHI S. , TOTARO P. 
Published: November 2018

Aim:
The clinical impact of AF in postoperative outcome following CABG surgery is still a controversial issue. In this study we sought to elucidate the real clinical impact of transient and persistent postoperative AF (TPOAF and PPOAF) occurring in patients previously in SR undergoing CABG surgery.

Methods:
All patients undergoing isolated CABG surgery during the last two years period at our Division were enrolled in this study. History of previous paroxysmal AF was not exclusion criteria, providing the presence of SR at hospital admission. Both TPOAF and PPOAF were then correlated to the incidence of postoperative unfavourable events such as death, mayor and minor complications. Incidence of AF recurrence, in patients discharged in SR, was also investigated.

Results:
175 patients (mean age 67 + /-11, male 84%) were enrolled. Postoperative incidence of TPOAF and PPOAF are shown in Fig 1a. Cumulative outcomes are summarized in Fig 1b. Mechanical Ventilation time, ICU and total hospital stay of TPOAF patients were not significantly increased, while ICU stay was higher. compared to stable sinus rhythm patients. TPOAF, was not risk factor for any of the complications considered (inotropic support, infections, bleeding and blood transfusion). At 1-year follow up 2 pts (5%) presented recurrence of AF.

Conclusions:
In patients in SR undergoing satisfactory isolated CABG surgery, transient postoperative AF, despite being a frequent event, usually does not impact significantly postoperative outcome. In such patients, furthermore, the incidence of recurrence of AF, even without a maintenance therapy is quite low.
RF34 PARADOXICAL ARTIFICIAL CORDS TECHNIQUE TO TREAT SAM IN HOCM
Authors: KASSEM S. 
Published: November 2018

Introduction:
The Systolic Anterior Motion (SAM) of mitral valve (MV) associated with the asymmetric hypertrophy of left ventricular septum are the two components responsible for left ventricular outflow obstruction (LVOTO) in Hypertrophic Obstructive Cardiomyopathy (HOCM). The transaortic left ventricular septal myomectomy has been proposed as the gold standard surgical procedure for symptomatic patients with severe HOCM since the late 1960 s.

Objective:
We have previously described one technique to prevent SAM post MV repair, the so-called “paradoxical artificial cords to prevent SAM after MV repair”. The aim of this article is to demonstrate the efficacy of this technique also to treat SAM in HOCM patients, in case of concomitant moderate septal myectomy.

Methods:
The subjects of the study are 5 patients with both SAM and LVOTO. All of them have been surgically treated, performing moderate transaortic septal myomectomy and correction of SAM by paradoxical artificial cords and ring annuloplasty.

Results:
The postoperative course of all patients was regular. No one of them developed the usual complications of this surgery (Ventricular Septal Defect [VSD] or Pacemaker [PM] implantation). Transthoracic Echocardiography TTE has demonstrated good result of the early postoperative interventricular gradient. The MV function was preserved and free of SAM.

Conclusion:
This technique could be considered as a valid treatment for SAM in patients with HOCM and LVOTO, if associated with moderate septal myectomy. The combination of these two surgical procedures is particularly important to avoid complications, especially VSD, in patients with a relatively thin interventricular septum, even in presence of hypertrophy.

Authors: Travaglini S. , Bonalumi G. , Naliato M. , Cavallotti L. , Dozio A. , Alamanni F. 
Published: November 2018

Background and aim:
Constrictive pericarditis (CP) is characterized by dense fibrosis and adhesions that encase the heart into a rigid non-pliable pericardium. The surgical management remains the most effective treatment for this patients, who have high rates of morbidity and mortality without therapy. We evaluated the current results and the predictors of in-hospital complications for isolated pericardiectomy in our centre.

Methods:
Between October 2007 and September 2017, twelve patients (M/F 83.3/16.7%) underwent pericardiectomy for constrictive pericarditis; mean age was 61.4 ± 12.7 years, 50% of patients were in NHYA class III, 16.7% of patients in NYHA class IV. The operative approach was median sternotomy in all patients and cardiopulmonary bypass has been used only in one patient.

Results:
The most common etiologies of CP were idiopathic (91.6%), post-operative + post-radiation (8.4%). Total pericardiectomy was performed in 91.7% patients. 33.4% of patients had pericardial calcification. The mean pre-operative EF and pulmonary pressure (PAPs) were 60.7 ± 11.6% and 32.3 ± 10.6 mmHg respectively. 16.7% of patients died during hospitalization (one for hepatic failure due to cirrhosis, one for sepsis), 16.7% of patients died during the follow up period (one death at 8 years). The mean post-operative EF and PAPs were 57.8 ± 7.7% and 27.3 ± 12.4 mmHg respectively. Improvement of clinical conditions (dyspnea reduction) was seen in all patients.

Conclusions:
Total, isolated pericardiectomy is associated with reasonable perioperative mortality. This procedure confers significant
RF62 PREVENTION OF STERNAL WOUND INFECTION WITH PREVENA DRESSING
Authors: D’Alessio A. , Hutton S. , Krasopoulos G. 
Published: November 2018

Background:
Sternal wound infections are a common complications in cardiac surgery. Our aim is to investigate if negative pressure on close wound with Prevenatm dressing might be a good method of prevention in selected high risk patients.

Methods:
We retrospectively reviewed 1115 consecutive patients that had cardiac surgery operation at Oxford University Hospital from January 2017 to May 2018. A single surgeon used Prevena dressing as prevention for wound infections in a group of high risk patients. The dressing was applied in theatre at -125mmHg and removed prior to discharge. The choice of the patient was led by surgeon decision with a Fowler score greater than 10.

Results:
25 patients received Prevena dressing, 15 of them underwent CABG. Only one developed superficial wound infection, but his Fowler score was 26 (predicted infection 16%). In our department sternal wound infection for heart operations was 2.4% (3.9% in CABG group). The average Fowler score in Prevena group was 16.8 and 18 in CABG sub-group with a predicted wound infection respectively of 6.6% and 8.2%. The wound infection rate on Prevena was 0% in the non-CABG group and 6.6% in CABG group. The cost of Prevena is 330£, while the cost per day of a patient with wound infection can be as high as 2000£

Conclusion:
Close incision negative pressure therapy with Prevena dressing is a cost effective and safe tool in selective high risk patient that can help reducing the incidence of sternal wound infection in selected high risk cardiac surgical patient.

Authors: Pagnin C. , Tarzia V. , Tessari C. , Fabozzo A. , Bottio T. , Tiso L. , Gerosa G. 
Published: November 2018

Background and aim:
Driveline infection (DLI) is a common and serious complication in patients undergone left ventricular assist devices (LVAD) implant. Prevention of DLI has demonstrated to be crucial in improving patients’ clinical outcomes. Aim of this study was to create a standard of care for patients with different exit-sites (ES) of LVAD cable.

Methods:
From December 2008 to March 2018, 136 patients undergone LVAD implantation. A retroauricolar cable (RAC) was associated to Jarvik 2000 (=62 pts), whereas abdominal cable (AC) with HVAD (=47 pts), HM2 (=2 pts) and HM3 (=25 pts). Two different medication strategies were used, according to different exit-sites. A not-occluding medication, which facilitates re-epithelization and allows patient self-care, was used for RAC (Fig.1A). For AC, on the contrary, an occluding, waterproof and breathable medication was preferred as it prevents infection while it favors wound healing maintaining a dry environment (Fig.1B).

Results:
Overall DLI was 11.8% (16 patients). In detail, infections were 6 (9.7%) and 10 (13.5%) in RAC and AC patients, respectively. Median time of DLI was 243 days (IQR: 113-514). Freedom from DLI was comparable in both RAC and AC groups using not-occluding and occluding medications as appropriate.

Conclusions:
Medication of driveline should be calibrated based on exit-site drive-line. This novel approach resulted safe and effective for DLI prevention and easy to manage.

Authors: Tarzia V. , Piperata A. , Tessari C. , Rubino M.G. , Zanella F. , Pittarello D. , Gerosa G. 
Published: November 2018

Background and Aim:
AngioVac system is a vacuum-assisted venous drainage device recently introduced into clinical practice for the removal of fresh and/or soft emboli/thrombi from vessels and right atrium. The aim of this study was presenting our center experience.

Methods:
From July 2016 to July 2017, 6 patients (mean age 58 ± 15 years) were treated with AngioVac system for right atrial masses (=4, 66.7%, 2 of these were electrode lead vegetations) and thrombosis of inferior vena cava (=2, 33.3%). We used both femoral and jugular vein percutaneous accesses and echo- or fluoroscopy guiding.

Results:
Therapeutic success (defined as a complete aspiration of the mass or return to an anterograde caval flow) was achieved in 5 cases (83.3%). One percutaneous approach was converted in open-chest because of pericardial tamponade and the mass suction was performed directly through the right atrium. Median intensive care unit stay was 1 day and all patients were discharged in good clinical conditions. At 1-year follow-up, all patients were alive.

Conclusions:
In our experience, AngioVac is a safe and reliable device that allows good results and patient's fast recovery. Because the procedure requires patient monitoring and the use of venous-venous extracorporeal membrane oxygenation, we suggest performing it in cardiac or hybrid operating room.

In work results of the research executed at 50 patients with hemorrhagic shock of the 3rd degree are presented. It is revealed that at the remaining shock phenomena, elimination of deficiency of oxygen at patients happens due to high consumption of oxygen fabrics which is carried out only due to his increased extraction from arterial blood. At elimination of symptoms of shock at patients correction of deficiency of oxygen is carried out at the expense of two mechanisms: increases in productivity of heart and his increased extraction from arterial blood.

Published: November 2018

Teaching and learning process is an essential aspect of a successful English teaching and learning. Reading skill is one of the language skills in English which gives a huge input to the learner. Nevertheless, it is mostly found that reading material and its exercises examine explicitly of what have been learned. Recently, multimodal texts become more popular in educational aspect especially the use of multimodal text in the teaching and learning reading. Multimodal text is a text that contains semiotic mode which covers gesture, visual image, document, layout, music, architectural design, etc. This study interviewed 10 Junior High School students and 1 English teacher regarding the use of multimodal text in reading class. The design of the study was a qualitative descriptive study which investigates the use of multimodal texts in teaching learning process in Indonesia compare to other countries. This study is expected to have a deeper insight and significant contribution for the English pedagogy.Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â

THE USE OF MULTIMODAL TEXT IN ENHANCING ENGINEERING STUDENTSâ€™ READING SKILL
Authors: Cahyaningati Desi Tri , Lestari Lies Amin 
Published: November 2018

Abstract
It is believed that the studentsâ€™ low reading proficiency, as shown in their TOEIC scores, is due to their poor reading habit. One of the ways to overcome such a problem is by facilitating them with a lot of reading practices in an extensive reading program. Since today non-printed multimodal texts (NPMT) and Linear texts (LT) are available in the society, an experiment on which mode is most effective to enhance the studentsâ€™ reading proficiency needs to be done. This study aims to investigate the effect of implementing non-printed multimodal text in an extensive reading program on the studentsâ€™ reading comprehension. Two groups of students undertaking engineering major at a polytechnic in Surabaya, one group was exposed to NPMT and the other to LT in a one-semester extensive reading program, were chosen to be the subject of this quasi experimental study. A pretest and posttest on TOEIC were conducted to measure the studentsâ€™ reading proficiency (only the reading scores of the test were analysed for the purpose of the study). The t-test analysis using SPPS for windows 23 shows that there is a significant difference in achievement between those who are exposed to NPMT and LT after the reading program ends (p-value = 0.010). The NPMT group gain better reading proficiency than that of the LT. It means the use of non-printed multimodal text in extensive reading can boost the studentsâ€™ reading comprehension.
