RESUMO
Abstract We describe a rare case of isolated right ventricular inferior free-wall rupture and cardiogenic shock caused by occlusion of the distal left circumflex coronary artery. Our case highlights the central role of transthoracic echocardiography in identifying unexpected conditions that can guide management - in our case involving early surgical intervention, thus leading to favourable patient outcomes.

Abstract Introduction: In this study, patients before and after cardiac surgery with cardiopulmonary bypass (CPB) and control subjects were evaluated for erythrocyte glutathione peroxidase, catalase and superoxide dismutase enzyme activities, in addition to glutathione, malondialdehyde, serum total sialic acid, lipid-bound sialic acid, total antioxidant status, trace elements and mineral levels. The correlation of these variables with coronary artery disease (CAD) was also assessed. Methods: A total of 30 CAD patients and 30 control subjects were included in the study. CAD patients were divided into three groups: before surgery (BS), first day after surgery (1st day AS) and seventh day after surgery (7th day AS). Results: Malondialdehyde (MDA) and total sialic acid (TSA) levels were significantly higher in CAD (BS) than in the control group (P<0.05, P<0.05). In addition, GSH and TAS levels were significantly lower in the 1st day AS group than in the control group (P<0.001, P<0.01). Moreover, Co, Cu, Mg, Se, V and Zn levels were significantly lower in CAD (BS) group than in the control group (P<0.01, P<0.01, P<0.01, P<0.01, P<0.05, P<0.001). Conclusions: It was concluded that the levels of LDL-C, total cholesterol, triglycerides and CRP significantly associated with parameters, as well as Cu, Ca and SOD activity, should be measured together to monitor CAD. It is also considered that measuring TSA and MDA might be an appropriate choice for biomarkers of CAD.

OBJECTIVE: To investigate the correlation between cardiac output values and renal neutrophil gelatinase-associated lipocalin (NGAL) levels as a biomarker of renal ischemia. METHODS: Forty patients, who underwent off-pump coronary artery bypass (OPCAB) surgery and in whom the positioning of the heart was fixed with simple suspension sutures without a mechanical stabilizer, were included in the study. Continuous cardiac output (CO) measurements were recorded using the arterial pressure waveform analysis method (FloTrac sensor system) in the perioperative period. CO was recorded every minute during non-anatomical cardiac positioning for left anterior descending artery (LAD), diagonal artery (D), circumflex artery (Cx), and right coronary artery (RCA) bypasses. Serum NGAL samples were analyzed in the preoperative, perioperative, and postoperative periods. RESULTS: The CO values measured at various non-anatomical cardiac positions during distal anastomosis for LAD, D, Cx, and RCA were significantly lower than pre- and postoperative values measured with the heart in normal anatomical position (3.45±0.78, 2.9±0.71, 3.11±0.56, 3.19±0.81, 5.03±1.4, and 4.85±0.78, respectively, P=0.008). There was no significant difference between CO values measured at various non-anatomical cardiac positions during distal anastomosis. Although there was no significant correlation between NGAL levels and age, duration of surgery, preoperative CO, D-CO, RCA-CO, and postoperative CO measurements, there was a significant correlation between NGAL levels and LAD-CO (P=0.044) and Cx-CO (P=0.018) at the postoperative 12th hour. CONCLUSION: Full revascularization may be achieved by employing the OPCAB technique while using simple suspension sutures without a mechanical stabilizer and by providing safe CO levels and low risk of renal ischemia.

OBJECTIVE: To evaluate the diagnostic accuracy of digital panoramic radiograph (DPR) for detection of carotid artery calcification (CAC) confirmed by Doppler Ultrasonography (DUSG) and to clarify the relationship between between CAC identified by DPR and cardiovascular events through a 5 year follow-up period. METHODS: Of 3600 consecutive patients examined, 158 patients presented with CAC as detected by DPR. The final study group was composed of 96 patients who had CAC confirmed by DUSG or CT angiogram. The control group was composed of 62 patients who has normal DUSG. The end point of the study was the occurrence of any cardiovascular event. RESULTS: 72 (75%) of the 96 patients with CAC confirmed by DUSG (16 patients had significant stenosis) had bilateral and 24 (25%) had unilateral CAS as detected by DUSG. There was a low agreement between the examination results with a κ value of 0.488 (p < 0.005) for calcification. Study data revealed that smoking, chronic obstructive pulmonary disease (COPD), diabetes mellitus (DM) and diastolic hypertension were significantly more common in patients with CAC than the control group (p < 0.05). During the follow-up period, 13 subjects had myocardial infarction and 1 subject died; in the control group, 1 patient died after MI and 1 patient died of a non-cardiac event. CONCLUSION: Patients with CAC detectable by DPR concomitant with COPD, DM, smoking or diastolic hypertension are more likely to suffer from vascular events. Therefore, patients with detectable carotid plaque in DPR require referral to a cardiovascular surgery clinic for further investigations.

Pseudo-Kaposi sarcoma is a rare, vasoproliferative skin disease usually caused by an underlying vascular malformation or venous insufficiency. Unusual forms such as amputation stumps and lower extremity paralysis have been also reported. However, its emergence in the leg from which the saphenous vein was harvested following peripheral artery disease and coronary artery bypass surgery has not been previously reported. We, herein, present a 78-year-old female case who developed pseudo- Kaposi syndrome in her left leg, which was affected by peripheral artery disease following the removal of the saphenous vein six months after coronary artery bypass grafting.
RESUMO
PURPOSE: The main purpose of this study was to evaluate the influence of any of the four domains of the QoL score in CVD patients of classes C0-C4 and to analyze the correlation between the QoL and types of treatment modalities, and an additional aim of the present study was to compare QoL levels of patients with CVD and healthy participants and was to examine the factors associated with QoL in CVD patients. METHODS: The sample was composed of 501 patients with primary superficial venous reflux (28.5 % male and 71.5 % female) who answered 100 % of the questions in the World Health Organization Quality of Life (WHOQoL-BREF) questionnaire. After a clinical and duplex examination, the patients were categorized as C0-C4, according to the CEAP classification. The relationships between WHOQoL-BREF domains and gender, age, occupation, BMI, the clinical classes of the CEAP classification and four different treatment modalities according to guideline were analyzed. RESULTS: For the WHOQOL-BREF test battery, the patients with CVD had worse values, as compared with the control group participants. The differences were significant for the physical (77.81 ± 12.75 vs. 59.18 ± 12.90, p < 0.001), the psychological (74.78 ± 11.37 vs. 60.21 ± 14.70, p < 0.001), the social relationships (76.56 ± 13.56 vs. 63.07 ± 21.37, p < 0.001) and the environmental (70.27 ± 13.36 vs. 50.16 ± 11.39, p < 0.001) health scores. The patients with CVD had worse WHOQOL-BREF scores at initial, compared with the 6-month follow-up scores. CONCLUSION: This study shows that in spite of undergoing therapy, the subsequent QoL scores did not improve significantly, indicating that CVD continued to negatively affect the patient's life.

BACKGROUND: Left main coronary artery (LMCA) stenosis is a risk factor in coronary artery bypass grafting (CABG). Although improved outcomes of off-pump CABG have been well documented, LMCA stenosis is often perceived as a contraindicationfor off-pump CABG. In this study, we compared on-pump and off-pump techniques in high-risk patients with LMCA disease. AIM: Documentation of safety and feasibility of off-pump CABG in patients with LMCA disease. METHODS: One hundred ninty nine patients with LMCA disease and a EuroScore ≥ 5 were operated upon between 2007 and 2010. One hundred patients (Group I) were operated upon using off-pump techniques, while 99 (Group II) were operated upon using conventional on-pump techniques. Perioperative variables and outcomes at first six months were compared. RESULTS: Despite higher mean age and EuroScore (70.9 ± 4.8 vs. 65.6 ± 7.9, p < 0.001, and 6.09 ± 0.8 vs. 5.31 ± 0.68,p < 0.001, respectively), and lower ejection fraction (41.4 ± 7.3 vs. 49.0 ± 6.2, p < 0.001), hospital mortality (1% vs. 6.1%,p = 0.065), postoperative inotropic support (9% vs. 48.4%, p < 0.001), blood loss (680.6 ± 265.0 vs. 847.2 ± 382, p < 0.001) and transfusions of blood (0.57 ± 0.79 U vs. 1.49 ± 0.82 U, p < 0.001), and hospital stay (6.57 ± 2.04 vs. 7.68 ± 3.44,p = 0.006) were lower in Group I. In both groups, mean number of distal anastomoses and completeness of revascularisation were similar. CONCLUSIONS: Using the off-pump technique is safe and improves postoperative early outcomes in high-risk patients with LMCA disease.

Post-traumatic pulmonary pseudocyst is an uncommon cavitary lesion of the lung, which generally develops after blunt chest trauma. We saw a 22-year-old man with chest trauma, hemopneumothorax, and hemoptysis, on the day he fell from an electrical pylon. Intubation in the emergency department was followed by 4 days of mechanical ventilation. Computed tomogram found a post-traumatic pulmonary pseudocyst. On hospital day 6 he developed pneumonia, which we treated with ceftazidime plus gentamycin. He was discharged on hospital day 20, and a month later the pseudocyst had resolved without complications. Diagnosis of post-traumatic pulmonary pseudocyst may require computed tomography, and some complicated cases may require surgery.
