(p = 0.208). Body weight was not significantly different between the two groups 3.23 ± 0.65 and 2.98 ± 0.48, respectively. ICU stay and total hospital stay were also comparable 19.75 ± 11.14 days versus 14.21 ± 10.59 days and 34.77 ± 26.89 days versus 26.86 ± 20.17 days, respectively. Most of our patients were left with open chest 66 (75.0%) in the BT group and 24 (82.8%) in the Sano group, (p = 0.278) for several days. ECMO was used for 17 patients (19.3%) in BT group and 5 patients in the (17.2%) in Sano group (p = 0.522). In–hospital mortality was 11 (12.5%) in the BT group and 5 (17.2%) in the Sano group, (p = 0.357). None of the patients received heart transplantation due to its unavailability. Conclusion: The Norwood operation can be successful with good results that warrant offering treatment to most newborns with HLHS in our setting. Lack of heart transplantation and perceived poor outcomes should not be considered sufficient reasons to deny surgical care to HLHS patients. In this study, there is no demonstrable difference in early outcomes between the BT shunt and the Sano shunt.

lowed by the development of the speckle tracking imaging. Strain and strain rate imaging can detect myocardial deformation which is the basis of myocardial function, thus with impaired myocardial perfusion the amount and rate of deformation decreases. Methodology: Thirty patients with SCAD and significant single vessel left anterior descending (LAD) coronary artery stenosis, diagnosed by invasive coronary angiography, undergoing elective percutaneous coronary intervention (PCI) of the LAD lesion with no significant lesions in the other coronary vessels, left circumflex (LCX) and right coronary artery (RCA). Patients with diabetes, regional wall motion and reduced left ventricular systolic function were excluded. Regional systolic strain and strain rate was measured in the ischemic LAD segments which are six, apicoseptal, mid anteroseptal, basal anteroseptal, apicoanterior, mid anterior and basal anterior, and measured in the non-ischemic LCX and RCA segments, before elective PCI of LAD and three months later. Results: By comparing the strain and strain rate of the ischemic segments before and after PCI there was significant improvement of the systolic strain while there were non-significant changes in the non-ischemic segments. Conclusion: Tissue Doppler strain and strain rate imaging during resting echocardiography can be used to detect regional myocardial ischemia in patients with significant coronary artery stenosis.

Abstract type: Clinical Research. Presentation type: Oral Presentation. Introduction: Transcatheter aortic valve implantation (TAVI) is performed usually with preballoon dilation (PBD) which has its pros and cons. The aim of this study was to show the role of transesophageal echocardiographic (TEE) in selection of patients for TAVI without PBD and compare the results with those underwent PBD. Methodology: 62 consecutive patients with severe symptomatic aortic stenosis underwent TEE evaluation before TAVI. 2D and 3D TEE imaging was used to assess aortic valve for suitability for direct valve implantation without PBD. Using echocardiographic criteria including sinotubular junction diameter, intersinus diameter, valve area, calcification, and degree of AR, echocardiographer agreed with the interventionist to consider patients either for TAVI with PBD or without PBD. We have 2 groups, group A underwent TAVI without PBD (n = 23) and group B underwent TAVI with PBD (n = 39). Results: 62 patients (median age, 80.2 ± 11.7 years) with severe AS were evaluated. The mean aortic valve area was 0.74 ± 0.17 cm2. In group A, Edward valves were implanted in 21.7% (n = 5) and Core valves in 78.3% (n = 18). In group B, Edward valves were implanted in 46.2% (n = 18) and Core valves in 53.8% (n = 21). Post implantation balloon dilation to decrease or eliminate paravalvular leak was done in 21.7% (n = 5) in group A, vs 20.5% (n = 8) in group B, P = 0.9. In group A, residual paravalvular leak was seen in 13% vs 28.2% in group B, P = 0.2. Procedure-related mortality was not signiï:_-

Abstract type: Clinical Research. Presentation type: Oral Presentation. Introduction: The success of the surgical treatment for Hypoplastic Left Heart Syndrome (HLHS) outside North America and Europe has not been well demonstrated. Furthermore, the optimal type of shunt associated with the Norwood operation is not yet determined. In this retrospective study we report the outcomes of the Norwood operation from a single institution and compare outcomes for patients receiving either a modified Blalock ‘‘Taussig shunt (BT) or a non-valved right ventricle to pulmonary artery (Sano) shunt. Methodology: Between January 2004 and December 2014, 117 patients underwent the Norwood procedure at King Faisal Specialist Hospital in Jeddah, Saudi Arabia. BT shunt was done in 88 patients and Sano shunt was done in 29 patients. Their electronic and paper charts were reviewed and the outcomes reported. Results: The mean age at surgery was 28 ± 17.13 days in the BT group and 33.79 ± 18.67 days in the Sano group
