The effort of searching God that be done by human, some of them really find God but also many of them that be lost in the forest of Metafisisme. The discussion of philosophy and religion is the case that very interesting, even many philosophy which has been discussed about them, start from the contra until want to join both of them. In this case the contribution of philosophy and science is to accompany of faith to the God, within certain limits can support the various evidence of the truth of existence and the power of God which has been widely revealed by religion. Syari’at is the law of God, Which is not only legal that can’t be followed by philosophical reasoning. Islam came with the teachings, to be a fad for the people. In a definitive manner Syari’at become the way to face the God. Science and philosophy can move and grow because of the human mind and presence conviction. Science, philosophy or religion aims at least to deal with the same thing,that is the truth. However, the point of difference is in the source, science and philosophy sourced in ra’yu (mind of human). Whereas religion sourced in revelation. Science seek the truth by research, experience (empirical) and experiment as the exam. Philosophy approache the truth with exploration of common sense in radical (rooted), it does not feel bound by any, except by their own hands, that is logic.

Published: November 2018

Background and Aim:
In aortic root surgery, Bentall procedure has been considered the procedure of choice. Valve sparing root-replacement (VSRR) techniques have gained popularity, avoiding prosthetis-related complications. However, long-term data to support this tendency are still lacking, and most of the studies included emergency procedures, that could influence the outcome.
The primary end-point was survival. Secondary end-point was freedom from Major Adverse Events (MAEs), including death, aortic-valve reoperation, major haemorrhage, cerebrovascular events, aortic valve regurgitation (or dysfunction)>moderate.

Methods:
Data of patients who underwent Bentall operation and VSRR from 1990 to 2017 in our centre were analysed. Emergency operations were excluded. Aortic valve stenosis were excluded from Bentall group.

Results:
130 patients underwent Bentall operation (29 biological and 101 mechanical conduits). 98 patients underwent elective VSRR (64 reimplantation and 34 remodeling techniques). Among baseline and operative data, in Bentall group were more bicuspid valves p < 0.001, previous cardiac operations p = 0.04, lesser preoperative AF p = 0.05 and mean X-clamp time p = 0.001. Mean follow up duration was 158 and 76 months in Bentall and VSRR groups.
Univariate analysis for long-term mortality: Age (HR 1.07, 95%IC 1.04–1.11)
Univariate analysis for MAEs: Age (HR1.05, 95%IC 1.02–1.07), VSRR (HR 1.8, 95%IC 1.09–3.11)
Multivariate analysis for MAEs: Age (HR 1.04, 95%IC 1.02–1.07), VSRR (HR 1.7, 95%IC 1.016–2.91)

Conclusions:
Comparable long-term survival after Bentall operation and VSRR. Bentall operation seemed to offer better protection against MAEs than VSRR. VSRR procedures are technically demanding, and necessitate of a longer learning curve than the easily reproducible Bentall operation.
OC75 THE LONG TERM FATE OF CORONARY ARTERIES AFTER ARTERIAL SWITCH OPERATION FOR TRANSPOSITION OF THE GREAT ARTERIES

Published: November 2018

Background and Aim:
To analyse the long-term patency of coronary arteries and correlated factors in a cohort of patients undergone arterial switch (ASO) operation in our institution.

Methods:
This is a retrospective study of operative and postoperative data of 191 patients who underwent ASO between 1991 and 2016. All patients underwent clinical, echocardiographic and angiographic evaluation during follow-up; dobutamine-stress and treadmill test were performed when indicated. Variables included were: complex native coronary anatomy (Yacoub types B-E), aorto-pulmonary relationship (anterior aorta vs. syde-by-syde) dimensional-mismatch, coronary reimplantation technique (direct-punch vs. trap-door technique). Univariate analysis was performed by chi-squared test and ANOVA when necessary.

Results:
191 patients have been studied by elective invasive cardiac coronary angiography after ASO at a mean time of 2.7 ± 2.1years without any significant procedure-related complication. Mean follow-up after the ASO was 12.9 ± 6.6years. Nine patients (4.7%) had angiographic signs of coronary stenosis or occlusion:8/9were asymptomatic. All details are reported in Table 1. Neither TGA anatomical features, nor coronary anatomy,nor reimplantation technique were identified as risk factors for occurrence of coronary artery obstruction (univariable analysis p values 0.159, 0.282, 0.49 respectively).

Conclusions:
Coronary obstruction after ASO is a silent and often overlooked complication. Patients may not show any symptoms or instrumental evidence of myocardial ischemia even with severe lesions, and the ordinary non-invasive diagnostic tools could be inadequate. Routine angiographic catheterization represents a secure and effective tool for follow-up ensuring early identification of coronary disease.
In our experience, the extended mobilization of coronary ostia to avoid abnormal coronary tension/distortion, even by the excision of small conal branches, has led to low incidence of coronary obstruction. Thanks to this, neither coronary complexity is a risk factor anymore

Published: November 2018

Background:
Diastolic dysfunction (DD) and left ventricular (LV) remodelling subsequent to increased afterload in severe aortic stenosis (AS) affect left atrial (LA) function. Aortic valve replacement (AVR) restores afterload and potentially reverse the LV modifications. However, no markers have been able to predict the LV remodelling and the post-surgical clinical events.

Aim:
to assess the relationship between baseline LA function and the diastolic function response and the clinical events following isolated AVR.

Methods:
patients undergoing AVR for AS were prospectively enrolled. A comprehensive transthoracic echocardiography was performed before surgery and at 1 year follow-up (FU). Baseline Peak atrial longitudinal and contraction strain (PALS, PACS) were obtained. During one year FU, cardiovascular (CV) events (death, hospital admission for heart failure, ischemic heart disease or atrial fibrillation [AF]) were registered.

Results:
Sixty-seven patients were enrolled, 72 ± 8years, female 56%, EF 60 ± 8%, E/e’ 13 ± 6, PALS 23 ± 8%. A normal/grade-I diastolic function was registered in only 19/67 (28%) at baseline, in contrast with 43/67 (64%) at 1-year echocardiographic FU (p < 0.0001). Normal/grade-1 diastolic function at FU was associated only with baseline PALS (OR:1.19[1.05–1.41], p = 0.02) and PACS (OR:1.24[1.06–1.50], p = 0.006) During a mean FU of 2.4 ± 0.4 years, 10 (14%) patients had CV events. Events occurred in older patients (74 ± 5 vs. 71 ± 9 years, p = 0.3), with similar EF (61 ± 6% vs. 62 ± 12%, p = 0.7), reduced PALS (20 ± 4% vs. 24 ± 6%, p = 0.04) and PACS (10 ± 3% vs. 13 ± 3%, p = 0.002).

Conclusions:
impaired baseline LA function is related with CV events and echocardiographic findings following AVR, identifying a subset of patients with increased CV risk.
OC45 MORPHOLOGICAL MODIFICATION OF THE AORTIC ANNULUS IN TRICUSPID AND BICUSPID VALVES AFTER AORTIC VALVE REIMPLANTATION PROCEDURE: AN ECG-GATED CT STUDY
Authors: Chirichilli I. , Irace F. , Weltert L.P. , Tsuda K. , Scaffa R. , Salica A. , Galea N. , De Paulis R. 
Published: November 2018

Objective:
To evaluate the modifications of size and shape of the aortic annulus during cardiac cycle by ECG-gated CT study after reimplantation procedure, between native Bicuspid Aortic Valves (BAV) and Tricuspid Aortic Valves (TAV).

Patients/methods:
From October 2014 to April 2018, we selected 27 patients scheduled for aortic valve reimplantation, who underwent preoperative and postoperative ECG-gated contrast-enhanced CT scan of the aortic root. A CT-scan study with reconstructed transverse double oblique view of the aortic base in systole and diastole was obtained. Major (MD) and minor diameters (md), perimeter (P) and area (A) were measured. The shape of the aortic annulus was considered “circular” or “elliptic” according to the Ellipticity Index (EI) defined as MD/md ratio: a value ≥ 1.1 was considered as “elliptic”.

RESULTS:
In all TAV patients postoperative CT scan revealed a significant modification of the aortic annulus from elliptic to circular shape (from MD/md ratio 1.28 to 1.08 (p < 0.05)). Type 0 BAV maintained the original circular shape (from 1.07 to 1.04, p = 0.212) while type 1 BAV shoved an intermediate behaviour (from 1,14 to 1,11, p = 0.417).

Conclusions:
This study confirms the expected reduction in aortic annulus size following the reimplantation procedure. The annulus in TAV was forced from native elliptical to circular shape. Instead, it was preserved in type 0 BAV maintaining an almost perfect circular shape. Type 1 BAV seem to lay in a spectrum between the previous ones, showing a reduction trend in Ellipticity Index, but without statistical significance.
