Abstract
We aimed to evaluate the correlation between aortic regurgitation severity and brain natriuretic (BNP) levels as a marker for left ventricular dysfunction. Sixty consecutive male patients (mean age 22 ± 3 years) with isolated chronic aortic regurgitation were enrolled in the study together with a control group of 30 age-matched healthy volunteers (group A). Patients were classified with regard to aortic regurgitation vena contracta width as follows: group B, < 3 mm, mild ( n = 16); group C, ≥ 3 and < 6 mm, moderate ( n = 26); group D, ≥ 6 mm, severe ( n = 18). BNP measurements were performed with a fluorescence immunoassay kit. BNP levels were increased in patients with aortic regurgitation, and severity of regurgitation had a significant influence on BNP levels. This effect can be explained by the volume loading effect of aortic regurgitation.

Abstract
We investigated the clinical significance of brain natriuretic peptide (BNP), a cardiac hormone, in chronic obstructive pulmonary disease (COPD). Subjects were 38 patients with stable COPD, of whom 20 had cor pulmonale (CP), and 22 were healthy individuals. Plasma BNP levels were measured and pulmonary arterial pressure (PAP) was estimated by echocardiography. Arterial blood gas analysis, forced vital capacity (FVC) and forced expiratory volume in 1 s (FEV1) were also recorded. BNP levels of patients with COPD were higher than those of controls (48.2 ± 37.5 and 9.3 ± 3.0 pg/ml). Patients with CP had a higher mean BNP level with respect to those without CP (73.9 ± 35.8 and 21.0 ± 10.2 pg/ml, respectively). BNP levels correlated with PAP ( r = 0.68), partial arterial oxygen pressure ( r = −0.70), FEV1 ( r = −0.65) and FVC ( r = −0.52). We have concluded that BNP determination has a role in the diagnosis of CP in patients with COPD.

Abstract
Atherosclerosis plays an important role in the etiopathogenesis of coronary artery ectasia (CAE). Inflammation markers may play a part in the pathogenesis of CAE. We aimed to assess the association between the CAE and the neutrophil–lymphocyte (N/L) ratio. Consecutive eligible patients (n = 181) were divided into 3 groups: patients with CAE, those with newly diagnosed coronary artery disease (CAD), and those with a normal coronary angiogram. The N/L ratio and mean platelet volume (MPV) were measured as part of the automated complete blood count. There were no statistically significant differences in N/L ratio and MPV between the CAE and the CAD groups. The N/L ratio and MPV were significantly higher in patients in both CAE and CAD groups compared to those in the control group ( P < .01). An increased N/L ratio may play a role not only in the pathogenesis of CAD but also in the pathophysiology of CAE.

Abstract
Neutrophils and lymphocytes (N/L) ratio and carotid intima–media thickness (C-IMT) value have been studied as new predictors of cardiovascular risk. We aimed to investigate N/L ratio and C-IMT value in patients with cardiac syndrome X (CSX) and compare patients with coronary artery disease (CAD) and normal participants. A total of 288 participants were enrolled in the study. The N/L ratio and C-IMT value were compared among the 3 groups. There were no statistically significant differences in N/L levels between CSX and CAD groups. The N/L ratio was found significantly increased in patients with CSX and CAD, compared to the control group. Patients with CAD and CSX had significantly higher C-IMT value compared to control participants. Significant positive correlation was found between C-IMT value and plasma level of N/L ratio. The relationship among CSX and higher N/L ratio level and C-IMT suggests that endothelial dysfunction may contribute to the etiopathogenesis of the CSX.

Abstract
Prehypertension is characterized by an increased cardiovascular risk and by an increased prevalence of target organ damage compared with the pure normotensive state. The present study was designed to assess in prehypertensive subjects the possible relationships between early left ventricular dysfunction, vascular inflammation and aortic stiffness. The study population consisted of 31 untreated prehypertensive subjects (age: 34 ± 6 years, mean ± SD) and 31 age-matched pure normotensive controls. Left ventricular function was assessed by echocardiography, aortic distensibility parameters were derived from aortic diameters measured by ultrasonography, and high-sensitivity C-reactive protein was assessed by latex-enhanced reagent. Prehypertensive subjects displayed a significantly lower E/A ratio and a significantly greater deceleration time and isovolumetric relaxation time compared with normotensive controls. They also displayed aortic systolic diameter, diastolic diameter and mean aortic stiffness index beta significantly increased while systo-diastolic diameter change, mean aortic distensibility and aortic strain were significantly reduced compared with controls. Values of inflammatory markers were increased. At multiple regression analysis, E/A ratio was significantly related to high-sensitivity C-reactive protein and aortic stiffness index beta, after correction for age, left ventricular mass index and mean blood pressure (β coefficient = -0.49, overall r(2) = 0.24, p = 0.01 and β coefficient =-0.46, overall r(2) = 0.21, p = 0.02, respectively). Thus, in prehypertension, left ventricular dysfunction is significantly related to vascular inflammation and aortic stiffness, suggesting that early cardiac and vascular alterations may have an increased inflammatory process as a common pathophysiological link.

Abstract
OBJECTIVE Cardiac syndrome X is characterized by angina-like chest pain, a positive stress test, and normal coronary arteries. A patient's mean platelet volume, which potentially reflects platelet function and activity, is associated with coronary atherosclerosis and endothelial dysfunction. The aim of the present study was to evaluate the mean platelet volumes of patients with cardiac syndrome X, those with coronary artery disease and normal subjects. METHODS Two hundred thirty-six subjects (76 patients with cardiac syndrome X, 78 patients with coronary artery disease, and 82 controls) were enrolled in the study. All of the subjects were evaluated with a detailed medical history, physical examination, and biochemical analyses. The mean platelet volumes were compared between the three groups. RESULTS The mean platelet volumes in the patients with cardiac syndrome X and with coronary artery disease were significantly higher than those that were observed in the control group. There were no significant differences in the mean platelet volumes between the cardiac syndrome X and the coronary artery disease groups. CONCLUSION We have established that patients with cardiac syndrome X and coronary artery disease exhibit higher mean platelet volumes compared to controls. Patients with cardiac syndrome X exhibited higher mean platelet volumes compared to the controls, reflecting the presence of subclinical atherosclerosis. These findings suggest that, in addition to endothelial dysfunction, the presence of atherosclerosis may also contribute to the etiopathogenesis of cardiac syndrome X.

Abstract
OBJECTIVE The aim of this study was to evaluate the diagnostic and the prognostic value of a laboratory panel consisting of mid-regional pro-atrial natriuretic peptide (MR-proANP), procalcitonin (PCT), and mid-regional pro-adrenomedullin (MR-proADM) for patients presenting to the emergency department (ED) with acute dyspnea. METHODS We prospectively enrolled ED patients who presented with a chief complaint of dyspnea and who had an uncertain diagnosis after physician evaluation. Final primary diagnosis of the cause of shortness of breath was confirmed through additional testing per physician discretion. We recorded inpatient admission and 30-day mortality rates. RESULTS One hundred fifty-four patients were enrolled in the study. Congestive heart failure exacerbation was the final primary diagnosis in 42.2% of patients, while infectious etiology was diagnosed in 33.1% of patients. For the diagnosis of congestive heart failure exacerbation, MR-proANP had a sensitivity of 92.7% and specificity of 36.8%, with a negative likelihood ratio (LR-) of 0.16 and a positive likelihood ratio (LR+) of 1.44 (cut-off value: 120 pmol/L). For the diagnosis of an infectious etiology, PCT had a 96.5% specificity and 48.8% sensitivity (LR-: 0.58, LR+: 13.8, cutoff value: 0.25 ng/mL). As a prognostic indicator, MR-proADM demonstrated similar values: odds ratio for 30-day mortality was 8.5 (95% CI, 2.5-28.5, cutoff value: 1.5 nmol/L) and the area under the receiver operating characteristic curve in predicting mortality was 0.81 (95% CI, 0.71-0.91). CONCLUSION The good negative LR- of MR-proANP and the good positive LR+ of PCT may suggest a role for these markers in the early diagnosis of ED patients with dyspnea. Furthermore, MR-proADM may assist in risk stratification and prognosis in these patients..

Abstract
Background Proanthocyanidin is a bioflavonoid known to have protective effect against oxidative injury. We investigated the cardioprotective effect of proanthocyanidin. Material/Methods Thirty-two Rattus Norvegicus rats were categorized equally as the control group (CG), proanthocyanidin group (PCG), ischemia group (IG) and proanthocyanidin-treated group (PCT). Rats in CG and IG were fed standard rat food and PCG and PCT were fed standard rat food plus proanthocyanidin (100 mg/kg/day twice a day by oral gavage) for 3 weeks. In CG and PCG the myocardial samples were prepared immediately, and in IG and PCT hearts were placed in transport solution and kept at 4°C for 5 hours, then prepared for evaluation. Malondialdehyde (MDA) level, superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) activities were measured. Results MDA levels were significantly higher in IG and PCT than in CG and PCG. The activity of SOD was significantly lower in IG and higher in PCG than in the other groups. The activity of GPx was significantly lower in IG than in the other groups. The activities of CAT were significantly lower in IG and PCT than in the other groups and were significantly lower in IG than PCT. Histopathologic evaluation revealed normal findings in CG and PCG. While ischemic injury was observed in IG, the content of muscle fibers was better preserved in PCT. Conclusions Proanthocyanidin may have a protective effect on myocardial ischemic injury.

Abstract
The involvement of autonomic imbalance has been reported in the pathogenesis of hypersensitivity reactions. Allergic diseases are more frequent in children and some of predisposing factors may be changed according to the increasing age, but the involvement of autonomic imbalance has not been investigated in pediatric population. In this cross-sectional, case-control study, we evaluated the autonomic system by measuring heart rate variability (HRV) in pediatric patients with allergic rhinitis. Thirty-five pediatric patients with allergic rhinitis and 36 healthy children (mean age 11 +/- 2.7, and 12 +/- 3 years, respectively) were enrolled in the study. Age and gender were not different between the groups. The diagnosis of allergic rhinitis was based on the history, symptoms, and skin prick tests. Participants with acute infection, nasal polyposis, bronchial asthma, and any other medical problems, assessed by history, physical examination and routine laboratory tests, were excluded. Twenty-four hour ambulatory electrocardiographic recordings were obtained, and the time domain and frequency domain indices of HRV were analyzed. We found significant increase in calculated HRV variables in children with allergic rhinitis compared to controls, which reflect parasympathetic tones, such as number of R-R intervals exceeding 50 ms, root mean square of successive differences between normal sinus R-R intervals, the percentage of difference between adjacent normal R-R intervals, and high frequency. These results indicate that HRV is increased, which implies sympathetic withdrawal and parasympathetic predominance. We propose that autonomic imbalance may be involved in the pathophysiology of allergic rhinitis in pediatric patients.

Abstract
BACKGROUND Inflammation plays an important role in hypertension and in atherosclerosis. Inflammatory changes induced even in prehypertensive subjects can lead to increased arterial stiffness. The effects of perindopril on both inflammatory and aortic elasticity markers were tested in hypertensive patients. MATERIAL/METHODS One hundred nine hypertensive patients not taking any antihypertensive therapy were included in the study. Aortic strain, aortic distensibility, aortic stiffness index, and inflammatory markers, including CRP, IL-1alpha IL-1beta, and TNF-alpha, were measured in all patients before and after twenty weeks of perindopril therapy. RESULTS While aortic strain and distensibility showed statistically significant increases with perindopril therapy, the aortic stiffness index and inflammatory markers were found to decrease. CONCLUSIONS Perindopril therapy resulted in an improvement in aortic elastic properties. There was also an attenuation of inflammatory status of the patients as reflected by lower inflammatory marker levels compared with pretreatment values.

Abstract
BACKGROUND Acute renal failure (ARF) occurring after on-pump and off-pump cardiac surgery was assessed by urinary alpha glutathione S-transferase measurement (alpha-GST) in patients who already had renal dysfunction. METHODS Fifty-one patients with plasma creatinine levels ranging between 1.5 and 2.0 mg/dL were included in the study. On-pump coronary artery bypass was performed in 25 of them, and off-pump surgery in the other 25 patients. Urinary alpha-GST levels, plasma creatinine levels, creatinine clearance and fractional excretion of sodium were measured. RESULTS Urinary alpha-GST levels were found to be significantly increased at 24 hours postoperatively. A weak correlation was detected between alpha-GST levels and plasma creatinine, creatinine clearance and fractional excretion of sodium. Preoperative and postoperative 24 hour levels showed a positive predictive value for the occurrence of acute renal failure. CONCLUSIONS Tubular damage produced by cardiopulmonary bypass is not the only factor associated with postoperative ARF. Because factors independent of pump usage can adversely affect renal function, excluding pump usage alone is not sufficient to prevent postoperative ARF in patients who have preoperative renal dysfunction.

Abstract
Predicting in-stent restenosis has been subject of many investigations. Several candidates have also been proposed such as CRP. However, recent findings suggested that adiponectin may be a more sensitive marker for in-stent restenosis. These initial results should be confirmed by other large scale prospective trials.

Abstract
BACKGROUND Individual risk factors and, more importantly, global risk assessment tools such as the Framingham risk score have been used successfully for risk prediction especially in older patients. However, there is paucity of data about the coronary heart disease prediction in premature coronary artery disease patients with a low Framingham risk score. METHODS AND RESULTS We recruited 102 consecutive young patients without hypertension and diabetes mellitus in the study. All subjects had had chest pain and underwent coronary angiography since non-invasive diagnostic test results suggested ischaemia. Forty-five patients having at least one coronary lesion independent of severity were included in the study group.The remaining fifty-seven subjects without any coronary lesion were used as control group. Conventional and non-conventional risk factors were evaluated both in patients and control subjects. Framingham risk score and absolute 10-year hard CHD events risk were also calculated for each individual. The coronary heart disease group had a significantly higher smoking frequency as compared to the control group.They also had higher plasma levels of triglycerides, apolipoprotein B and apo B/AI ratio but a smaller LDL particle size.We failed to find any independent CHD predictor after logistic regression analysis. However, individual ROC curve analysis of risk factors revealed that apolipoprotein B, triglycerides and apo B/AI ratio have the highest area under the curve for coronary artery disease prediction. CONCLUSIONS The Framingham risk score may underestimate the true risk of an individual. Incorporating non-conventional risk factors such as apolipoprotein B and apo B/apo AI ratio may provide valuable information in these patients.

Abstract
BACKGROUND The effects of perindopril, an angiotensin-converting enzyme inhibitor, atenolol, a beta adrenergic receptor blocker, and amlodipine, a calcium channel blocker, were investigated in chronic alcohol administered rats. MATERIAL/METHODS Adult male Wistar rats (240-320 g) were used in the present study. Alcohol was given to rats on a modified liquid diet for 21 days. Perindopril (2.5 and 5 mg/kg), atenolol (5 and 10 mg/kg), and amlodipine (5 and 10 mg/kg) were injected into rats in different groups intraperitoneally for 21 days. Control rats were pair fed an isocaloric liquid diet containing sucrose as a caloric substitute for alcohol. Saline was injected into the control rats for 21 days. The hearts were removed after the rats were anesthetized by ether, and 1-mm3 samples from the ascending aortas were fixed. Five fields per aorta were examined and photographed with a transmission electron microscope. Blood alcohol levels were also measured spectrophotometrically. RESULTS Daily alcohol consumption of the rats was in the range of 12.09-15.50 g/kg. Blood alcohol concentrations were 145.63 mg/dl on the 21st day of alcohol consumption. Chronic alcohol consumption caused some marked aortic wall injuries. Perindopril, atenolol, and amlodipine at high doses, but not low doses, produced some significant beneficial effects on alcohol-induced aortic wall damage. CONCLUSIONS These results imply that perindopril, atenolol, and amlodipine may have protective effects on heavy chronic alcohol consumption-induced aortic wall injury in rats only in high doses.

Abstract
AIM To investigate the factors that are related to increased anxiety before elective coronary angiography. BACKGROUND Anxiety before coronary angiography is an important factor for complications. To know the factors for increased anxiety, it is important for nurse to prevent complications. DESIGN A cross-sectional study design was used. The study included 88 consecutive patients waiting for coronary angiography. Methods. A data-collecting form, which included questions about demographic features, health history and angiography, was completed by the participants on the day of coronary angiography. The level of state and trait anxiety was measured by Spielberger's State-Trait Anxiety Inventory. Multivariate Analysis was performed to disclose the independency of the relation between state anxiety and factors. RESULTS Both trait and state anxiety levels were found to be moderate (age = 46, SD = 9, 24-67 years and age = 40, SD = 10, 21-65 years, respectively). There was a significant relation between state and trait anxiety levels (r = 0.56, p < 0.001). Among the investigated factors, only the trait anxiety (p < 0.001) and time on waiting list (p = 0.020) were found to be independent. For predicting high level of state anxiety, the cut-off value of trait anxiety was found to be 48 with a sensitivity of 67% and specificity of 67% and cut-off value of time on waiting list was found to be seven days with a sensitivity of 83% and specificity of 52%. CONCLUSIONS The time on waiting list and trait anxiety levels are the most important factors for state anxiety level. To prevent high level of coronary angiography-related anxiety, those patients with trait anxiety level >48 and time on waiting list >7 days should be managed specifically. The preventive measures should be specifically focused on the connection between state and trait anxiety. RELEVANCE TO CLINICAL PRACTICE Nursing planning should be focused on patients especially those on a long-time waiting list and on patients with high trait anxiety level prior to coronary intervention.

Abstract
INTRODUCTION Although its accuracy has been documented in many studies, the proximal isovelocity surface area (PISA) method is not used widely for mitral valve area (MVA) measurement. In this study, we prepared a new nomogram and tested its use in MVA assessment. MATERIAL AND METHODS The study included 23 patients (age: 27 +/- 5 years) with mitral stenosis, of whom 7 were in atrial fibrillation. The MVA was measured by four methods: planimetry (PL) (reference method), pressure-half time (PHT), conventional PISA (CP), and nomogram (Nomo) methods. The nomogram included two unknowns: (1) r; the radius of the first PISA section; (2) a; the length of the border opposite to the PISA angle in the triangle with both adjacent borders of 1 cm. The nomogram was also tested for its popularity potential by eight echocardiographers, none of whom were included in the author list. RESULTS Mean MVA(PL) was 1.85 +/- 0.53 cm(2) (range: 0.72-2.99), mean MVA(PHT) was 1.72 +/- 0.56 cm(2) (range: 0.91-3.30), mean MVA(CP) was 1.69 +/- 0.45 cm(2) (range: 0.97-2.54), and MVA(Nomo) was 1.70 +/- 0.44 cm(2) (0.96-2.49). The nomogram correlated with planimetry (r = 0.87; P < 0.001), pressure half-time (r = 0.71; P < 0.001) and conventional PISA (r = 0.99; P = 0.000) methods. The nomogram method also correlated with planimetry in patients with atrial fibrillation (r = 0.81; P = 0.026). The echocardiographers found that the nomogram is superior to the planimetry and conventional PISA methods but inferior to the pressure half-time method in terms of simplicity. CONCLUSION The new nomogram is potentially helpful in measurement of MVA. It may be used as an additional method in assessing severity of mitral stenosis.

Abstract
Autonomic function is impaired in anemic patients with various etiologies such as vitamin B12 deficiency, sickle cell trait, and thalassemia major. However, there are insufficient data about autonomic functions in patients with iron deficiency anemia, the leading cause for anemia in the general population. In the present study we aimed to investigate the autonomic status in iron deficiency anemia by analyzing the heart rate variability (HRV). Age- and gender-matched 43 patients with iron deficiency anemia and 39 healthy subjects were undertaken into 24-hr Holter monitoring for assessing the HRV. We used serum levels of iron, iron binding capacity, C-reactive protein, vitamin B12, and folate to exclude other causes of anemia. While age, gender, vitamin B12 and folate levels were not different between the groups, HRV values were lower in patients with iron deficiency anemia compared to control group, which reflects parasympathetic withdrawal. Blood hemorheological factors such as decreased viscosity and/or altered red cell deformability may be responsible for this decreased parasympathetic activity. However, these components do not display remarkable contribution in iron deficiency anemia. Therefore, we speculated a probable link between anemia and the accentuated sympathetic activity that may be triggered by hypoxia sensed through carotid bodies. Despite lacking adequate convincing evidence concerning exact mechanism of carotid body activation, it is assumed as due either to hypoxia-related mitochondrial respiratory chain inhibition or potassium channel suppression that leads to intracellular calcium accumulation. In conclusion, the present study demonstrates an altered autonomic balance in patients with true iron deficiency anemia.

Abstract
BACKGROUND Use of the radial artery (RA) as a conduit in coronary artery bypass grafting (CABG) has become increasingly popular in recent years. The aim of this study was to compare the results of two different RA harvesting techniques. Use of the harmonic scalpel is suggested to be safe and additionally reduces spasm rates. MATERIAL AND METHODS From January 2000, the first 200 consecutive patients who underwent RA harvesting for CABG were enrolled in this study. Patients were divided into two groups. RA was harvested by means of electrocautery + hemoclips in Group I and by harmonic scalpel + hemoclips in Group II. 30 patients (30 %) in Group I and 25 patients (25 %) in Group II were female. Mean age was 53.9 +/- 9.3 and 53.5 +/- 8.4 years in Group I and Group II, respectively. Hand circulation and ulnar collateral flow was assured with a modified Allen test in all patients preoperatively. During the operation perfusion of the hand was monitored by oximetric plethysmography. The distal end of RA was also explored and clamped with a soft vascular clamp to evaluate the saturation values in the groups. During the clamping period, oxygen saturation values did not decrease so we harvested RAs in all patients. RESULTS There were no statistically significant differences between the groups with the exception of the RA harvesting times, the postoperative analgesia requirements, the rate of vasospasm and the need for hemostatic clips. CONCLUSION Harmonic scalpel usage in RA harvesting causes less trauma to adjacent tissues; the analgesia requirements, the rate of vasospasm, the RA harvesting time and the need of hemostatic clips decreases. We conclude that the use of a harmonic scalpel for radial artery harvesting is safer and faster than the routine technique.

Abstract
OBJECTIVE Mitral regurgitation (MR) is a progressive disease of the mitral valve, which can be primary or functional. The assessment of left ventricular function in MR is still troublesome. In this study, we evaluated the validity of a new parameter, total dt, in patients with MR. METHODS Forty patients with severe MR constituted the study group. According to the transesophageal echocardiographic evaluation, the patients were dichotomized into two groups: (1) Primary MR; n = 21, (2) Functional MR; n = 19. The total dt was defined as the sum of time intervals from 1 msto 3 ms (positive dt) and from 3 ms to 1 ms (negative dt) on the CW Doppler recording of MR jet. It was compared to other indices of left ventricular function and left ventricular geometry, including ejection fraction, fractional shortening, myocardial performance index, coaptation distance, left ventricular volume and diameter, sphericity index, and parameters of diastolic function. RESULT The total dt correlated with myocardial performance index, coaptation distance, and sphericity index. It could differentiate between primary and functional MR with an area under curve of 0.878, followed by myocardial performance index with 0.860. The total dt > 104 ms was 79% sensitive and 81% specific for discrimination. CONCLUSION The total dt is useful for assessing left ventricular function and also for differentiating primary MR from functional MR.

Abstract
OBJECTIVE In this study, we investigated the relation between plasma adiponectin levels and other risk factors in a young patient population. MATERIAL AND RESULTS We enrolled consecutively 69 young patients (< 45 years) with coronary artery disease in the study group. he patient enrollment period was between February 2003 and November 2004. The control group consisted of 42 age- and sex-matched healthy subjects. Anthropometric, lipid and other variables including adiponectin, fasting glucose and plasma insulin levels were measured in all subjects. Appropriate statistical analyses were performed to determine the differences between the groups, the relation between adiponectin and other parameters and independent factors that predict CAD. There was a statistically significant difference between the groups in terms of lipid parameters (triglycerides, total cholesterol, HDL and LDL cholesterol). Mean plasma adiponectin levels were significantly lower in the patients (P < 0.05). Among the risk factors adiponectin had a significant negative association with the plasma triglyceride level (P < 0.01). Logistic regression analysis revealed triglycerides and adiponectin as independent predictors of CAD. The areas under the ROC curves of adiponectin and triglycerides were not different (P > 0.05). CONCLUSION We found a decreased plasma adiponectin level in young male patients with coronary artery disease. It may be a novel marker of atherosclerosis in young men.

Abstract
The complications linked directly to coronary artery catheter itself are very rare. We presented a case in which the broken right coronary artery catheter was successfully removed from the ascending aorta. The removal of catheter was accomplished via an aortic incision, which was created for saphenous vein graft in the site of anastomosis during an emergency coronary artery bypass graft surgery. We believe that a broken catheter in the aorta is a catastrophic event, which could be removed safely in the operating room even with concomitant bypass surgery.
