Objective<br />
Most thymic tumors are of epithelial origin with different clinical behavior and prognosis. Our aim was to study<br />
the histological subtype and tumor stage of thymic epithelial tumors in Iceland and evaluate the results of<br />
surgical treatment.<br />
Materials and methods<br />
16 consecutive patients (mean age 61 yrs, 10 males), diagnosed with thymic tumor in Iceland, from 1984 to <strong>2009</strong>,<br />
were studied retrospectively. The histological subtype was determined according to the new WHO classification<br />
(A-C) and the Masoka-system used <strong>for</strong> staging the tumors.<br />
Results<br />
Seven patients had local symptoms (chest pain, cough), seven were diagnosed incidentally and 2 were diagnosed<br />
during a work-up <strong>for</strong> myasthenia gravis. Benign tumours were 12, and thymic carcinomas four (25%). The histological<br />
subtype was type A (n= 4), type AB (n=2), type B1 (n=1), type B2 (n=5) and type C (n=4), with no B3 tumors.<br />
Majority of the tumors were on stage I (n=4) or II (n=5) but the carcinomas were two on each stage, III and IV.<br />
Twelve of the 16 patients underwent a radical resection of the tumor through a median sternotomy. There were no<br />
major complications and all the patients survived surgery. Overall crude survival <strong>for</strong> the 16 patients at 5 years was<br />
56%, 75% <strong>for</strong> thymomas and 0% <strong>for</strong> thymic carcinoma.<br />
Conclusions<br />
Tumors in the thymus are rare, most of them benign thymomas with excellent prognosis. For thymic carcinomas,<br />
however, the prognosis is poor and these patients usually die within one year from diagnosis.<br />

MYOCARDIAL REVASCULARIZATION IN PATIENTS WITH SEVERE LEFT VENTRICULAR<br />
DYSFUNCTION, IS ON PUMP BEATING THE PREFERABLE TECHNIQUE?<br />

Objective<br />
This study compares early outcomes after on-pump beating-heart CABG and conventional CABG in patients with<br />
ejection fraction (EF) less than 30%.<br />
Methods<br />
From 2005 to 2008, 167 patients with ejection fraction less than 30% underwent CABG on-pump beating-heart<br />
CABG was done in 75 patients (group 1) and 95 patients were done using conventional technique (group2). Twelve<br />
patients in the conventional CABG group required insertion of intra-aortic balloon pump initiation intra-operatively<br />
or postoperatively, whereas only 2 patients required this in the on-pump beating-heart CABG group.<br />
Results<br />
In-hospital mortality was less in the on-pump beating-heart CABG group (2.25% versus 3.68). Twelve patients in the<br />
conventional CABG group required insertion of intra-aortic balloon pump initiation intra-operatively or postoperatively,<br />
whereas only 2 patients required this in the on-pump beating-heart CABG group.The ventilation time was longer<br />
in conventional group it was 10± 12.3 versus 7.6±11.7. No significant difference was found in morbidity including<br />
stroke, renal failure. The incidence of postoperative atrial fibrillation was significantly less in on pump beating group<br />
as compared to CPB group it was happened in 6 patients versus 21 respectively. The duration of intensive care unit<br />
stay was 2.9 ±1.65 in group 1 while it was 3.7± 1.78 group 2. The hospital stay was also shorter in the on-pump<br />
beating-heart CABG group, it was 6.8± 1.43 versus 8.6 ±2.13 and it was significantly difference.<br />
Conclusions<br />
On-pump beating-heart CABG can be per<strong>for</strong>med safely on high-risk patients.<br />
