Abstract
Abstract
BACKGROUND
The number of lead removal of cardiac implantable electronic devices (CIED) has increased in recent years. The recent European registry (ELECTRa) did not include all European centers and not all lead extractions are possible to be performed transvenously.
AIMS
We aim to analyze all lead extraction procedures (transvenous or open surgery) performed in our center and the short- and long-term follow-up of these patients (pts).
METHODS
We retrospectively reviewed all lead extractions performed from 2008 to 2017. We analyzed pts´ characteristics (personal history, cardiovascular risk factors, indication for device implantation, laboratory tests); indications for extraction; techniques used and personnel that participate in the procedure, complications peri- and post-procedural and short and long-term follow-up.
RESULTS
A total of 189 pts (330 leads) were included (mean 69 ± 14 years, 73% male). The follow-up was 54 (IQR 20-87) months. Median time after implant was 47 (IQR 19-98) months. Lead explant was performed in 30 patients (16%) and lead extraction (at least one lead implanted >1 year or a lead requiring assistance of specialized equipment) in 159 (84%). Indications for removal are presented in figure A. In those who were infected, isolation of the microorganism was possible in 35% and Staphylococcus aureus was the most common agent (51%). 101 procedures (53%) occurred in the operating room, while 89 (47%) were performed in the electrophysiology laboratory, but 47% of those with the participation of a surgeon. On the total, cardiac surgeons were responsible for 75% of the procedures. Removal was tried in 330 leads (98 atrium lead, 199 right ventricle lead (79 defibrillator lead) and 33 coronary sinus lead). Of those, 298 were completely removed, 14 were partially removed (<4cm of a lead remained in the patient body) and 18 were not removed (radiologic failure). On an individual patient basis, clinical success was achieved in 185 patients (97%). Techniques used in the 330 leads were distributed in figure B. Surgical approach was necessary in 14 pts due to unsuccessful transvenous removal (n = 3), large vegetation in the lead (n = 4), concomitant valvular endocarditis (n = 2), other indication for open surgery (n = 4) and complicated transvenous removal (n = 1). Complications occurred in 6 patients: 3 persistent infections, 1 stroke, 2 vessel rupture. Related-procedural mortality was 1.5% (n = 3). The long-term survival of pts who performed open heart surgery was not different from those who underwent transvenous lead removal (logrank, p = 0.27) (figure C).
CONCLUSION
Although being a low volume center (19 procedures/year) and including pts with transvenous and open surgery, lead removal was associated with a high success rate with low all cause complication and mortality rates. Emergent surgery due to acute complications was very rare (0.5%) and open heart surgery was mostly programmed and not associated with a worse outcome.

Abstract
Abstract
Introduction
The concept of complete revascularization arises from the early stages on coronary artery bypass grafting (CABG). There are several different definitions applied across the literature, promoting a difficult comparison between studies. Despite the established importance of complete revascularization, there is no agreement which definition has the most impact on mortality.
Objectives
Evaluate the impact of the different definitions of complete surgical revascularization in late mortality.
Methods
Single center retrospective study of all consecutive patients submitted to isolated CABG with previous myocardial viability assessment (myocardial perfusion scintigraphy) from 2011 to 2016. Exclusion criteria: emergent procedures and previous cardiac surgery. The primary end-point was follow-up mortality (n=20). The population of study was162 patients with 22,2% female gender and a mean age of 66 years. The follow-up was complete in 98,8%, median time of 4,1 (IQR 3,0–5,5) years.
The completeness of revascularization was classified in all patients according to four different definitions (n=162 for each definition): Numerical (the number of stenotic vessels must equal the number of distal anastomoses applied); Functional (all ischemic myocardial territories are reperfused; areas of old infarction with no viable myocardium are not required to be reperfused); Anatomical Conditional (all stenotic main-branch vessels are revascularized) and Anatomical Unconditional (all stenotic vessels are revascularized, irrespective of size and territory supplied).
For each definition, statistical analysis was performed using the Kaplan-Meier method with log rank test and Cox proportional analysis (EuroSCORE II and revascularization definition).
Results
On univariate analysis, there was no significant statistical association between each definition of complete revascularization and follow-up mortality: numerical (p=0,694); anatomical unconditional (p=0,294); but a trend was found on functional (p=0,063) and anatomical conditional (p=0,084).
On multivariate analysis, incomplete functional revascularization increased the risk of follow-up mortality in 2,89 folds and anatomical conditional in 3,28 folds (Figure 1). The other definitions were not statistically associated with late mortality.
Conclusion
According to this study, complete functional and anatomical conditional revascularization definitions are determinants of follow-up mortality in a multivariate model including EuroScore II. The revascularization of all stenotic main-branch vessels (anatomical conditional) seems to have the highest impact, fact that we should be taken in consideration on daily work.

Abstract
The Ross operation is physiologically the best approach for aortic valve replacement. At the Hospital de Santa Cruz 22 consecutive pulmonary autograft operations have been performed in patients with a mean age of 49 (range 17-65) years. Six patients had mitral valve disease, two had aortic aneurysms and one had a ventricular septal defect. Subcoronary implantation of the autograft was performed in 20 patients. A partial inclusion aortic root replacement technique was used in one and the aortic root was replaced in another. There were no hospital or late deaths. Two patients required autograft replacement at 3 and 9 months postoperatively because of regurgitation. One of these cases was caused by an abnormality of the pulmonary valve and since then echocardiographic assessments of this valve have been performed routinely and have detected significant pulmonary incompetence in four patients who otherwise would have been operated on using the Ross procedure.

Abstract
The aim of this study is to establish anatomical landmarks for the trajectory of the large septal artery. Thirty hearts were dissected, 20 of which had no cardiac pathology and the remaining with different cardiac conditions. One large septal artery was located in 27 of these hearts, two large septal arteries in 2 and three large septal arteries in 1. For all cases there existed one large septal artery in the lower border of the anterior limb of the septomarginal trabecula. When more than one large septal artery was encountered, the first was located within the subendocardial outflow tract of the left ventricle, the second was in the lower border of the anterior limb of the septomarginal trabecula and the third 1.5 cm below the second.
