Diagnostic value of transthoracic echocardiography and computerized tomography for surgically confirmed late tamponade after cardiac surgery.

BACKGROUND: Late tamponade after cardiac surgery is a clinically obscure condition presenting significant diagnostic challenges, since it may be difficult to detect using routine imaging studies. This study is aimed to investigate the diagnostic value of transthoracic echocardiography (TTE) and contrast-enhanced computerized tomography (cCT) in the diagnosis of late tamponade following open-heart surgery. METHODS: A total of 88 patients who underwent reoperation after cardiac surgery with suspected late cardiac tamponade were included in this retrospective study. All the patients had TTE and cCT examinations before reoperation. The diagnostic values of these imaging modalities were investigated using surgically confirmed late tamponade as the standard. RESULTS: The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of an optimal cutoff value of greater than 3.1 cm pericardial fluid thickness on cCT images for predicting surgically confirmed late tamponade were 91.4%, 66.6%, 97.4%, 36.3%, and 89.7%, respectively. Accordingly, the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of TTE for the diagnosis of late tamponade were 34.1%, 50.0%, 90.3%, 5.2%, and 35.2%, respectively. The cCT provided false-negative results in seven patients (8%), while this figure was 54 (61.4%) for that of TTE. CONCLUSION: Computerized tomography imaging seems to represent a superior imaging technique in terms of visualizing the intrapericardial fluid collections after cardiac surgery and has the potential to readily diagnose late tamponade and effectively prevent unnecessary morbidity and mortality.

The prognostic value of fragmented QRS in patients undergoing transcatheter aortic valve implantation.

BACKGROUND: Although transcatheter aortic valve implantation (TAVI) can successfully correct aortic narrowing, pre-existing pathophysiological alterations in the left ventricle are still a concern in terms of long-term mortality. This study aimed to examine the predictive role of fQRS morphology on long-term prognosis in patients undergoing TAVI due to severe aortic stenosis. METHODS: A total of 117 patients undergoing TAVI due to severe aortic stenosis were included in this retrospective cohort study. Patients were assigned into two groups based on the presence (n = 36) or absence (n = 81) of fQRS. Predictors of long-term survival were estimated. RESULTS: In-hospital mortality was higher in fQRS group (5.5% vs. 1.2%, p = 0.0224). In the long-term, fQRS (OR: 3.06, 95% CI 1.29-7.27, p: 0.01), LVEF <50% (OR: 2.54, 95% CI 1.07-6.02, p: 0.03) and presence of atrial fibrillation (OR: 2.42, 95% CI 1.05-5.60, p: 0.03) emerged as significant independent predictors of short survival. CONCLUSION: Presence of fQRS on ECG, an indirect indicator of myocardial fibrosis, seems to have the potential to be used as a prognostic marker after TAVI procedure. Large prospective studies are warranted.

New Markers in Atherosclerosis: Thrombospondin-2 (THBS-2) and Leukocyte Cell-Derived Chemotaxin-2 (LECT-2); An Immunohistochemical Study.

BACKGROUND Current research investigating the role of THBS2 and LECT-2 in atherogenesis is very limited. Therefore, we designed this study to demonstrate the role of THBS-2 and LECT-2 in atherosclerosis at the tissue level in fresh specimens. MATERIAL AND METHODS A total of 32 patients who underwent coronary bypass surgery were enrolled. Aortic wall punch biopsies were obtained at the site of proximal aortosaphenous bypass graft anastomosis. A specimen of left internal mammarian artery (LiMA) was taken from the segment just proximal to its anastomosis. The aortic tissue is representive of the atherosclerotic tisue, and LiMA tissue is representative of the non-atherosclerotic area. The specimens were painted with CD68 for macrophage, and THBS-2 and LECT-2 antibodies for immunohistochemical staining. RESULTS Aortic THBS-2 levels were significantly lower, whereas aortic LECT-2 levels were significantly higher when compare to LiMA (14.4±9.9 (5-30) and 36.9±13.0 (5-60) p: 0.0001 and 20.3±15.0 (5-60) and 20.8±13,8 (10-30) p: 0.0001, respectively). CD68+ and monocyte level correlated significantly with AHA atherosclerosis grade (p=0.01, r=0.45 and p=0.001, r=0.56, Spearman's test). CD68+ level correlated significantly with LECT-2 levels in atherosclerotic aortic tissue (p=0.026, r=0.392, Spearman's test), whereas aortic TSBN-2 levels were not. CONCLUSIONS The present study has taken the first steps to highlight new markers in atherosclerosis by using immunohistochemical method. The study results suggest that the tissue levels of THBS2 and LECT-2 may correlate with the stage of atherosclerosis.

An epidemiological study to evaluate the use of vitamin K antagonists and new oral anticoagulants among non-valvular atrial fibrillation patients in Turkey- AFTER-2 study design.

OBJECTIVES: Atrial fibrillation (AF) is one of the most common causes of preventable ischemic stroke and is related to increased cardiovascular morbidity and mortality. There is a lack of data in Turkey on the use of new oral anticoagulants (NOACs), and time in therapeutic INR range (TTR) in vitamin K antagonist users and AF management modality. In this multi-center trial, we aimed to analyze, follow and evaluate the epidemiological data in non-valvular AF patients. STUDY DESIGN: Four thousand one hundred consecutive adult patients from 42 centers with at least one AF attack identified on electrocardiography will be included in the study. Patients with rheumatic mitral valve stenosis and prosthetic valve disease will be excluded from the study. At the end of one year, the patients will be evaluated in terms of major cardiac end points (death, transient ischemic attack, stroke, systemic thromboembolism, major bleeding and hospitalization). RESULTS: First results are expected in June 2015. Data about major cardiovascular end-points will be available in January 2016. CONCLUSION: The rates and kind of oral anticoagulant use, TTR in vitamin K antagonist users and main management modality applied in non-valvular AF patients will be determined by AFTER-2 study. In addition, the rate of major adverse events (MACEs) and the independent predictors of these MACEs will be detected (AFTER-2 Study ClinicalTrials.gov number, NCT02354456.).

The effects of levosimendan exposure on oxidant/antioxidant status and trace element levels in the pulmonary artery of rats.

We investigated both the effect of levosimendan and the role of oxidant/antioxidant status and trace element levels in the pulmonary artery of rats. Fourteen male Wistar albino rats were randomly divided into two groups of seven animals each. Group 1 was not exposed to levosimendan and served as a control. Levosimendan (12 µg/kg) diluted in 10 ml 0.9 % NaCl was administered intraperitoneally to group 2. Animals of both groups were killed after 3 days, and their pulmonary arteries were harvested to determine changes in tissue oxidant/antioxidant status and trace element levels. The animals in both groups were killed 72 h after the levosimendan exposure treatment, and pulmonary arteries were harvested to determine levels of the lipid peroxidation product MDA and the antioxidant GSH as well as the decreased activity of antioxidant enzymes such as SOD, GSH-Px and CAT. It was found that MDA levels increased in pulmonary artery tissues of rats after levosimendan administration. The GSH level decreased in the pulmonary artery of rats after levosimendan treatment. Co, Mn, Fe, Cd and Pb levels were significantly higher (P < 0.001) and Mg, Zn and Cu levels significantly lower (P < 0.001) in the levosimendan group compared to the control group. These results suggest that levosimendan treatment caused an increase in free radical production and a decrease in antioxidant enzyme activity in the pulmonary artery of levosimendan-treated rats. It also caused a decrease or increase in the levels of many minerals in the pulmonary artery, which is an undesirable condition for normal pharmacological function.

The effect of iloprost on renal function in patients with critical limb ischemia.

BACKGROUND: Iloprost, which has efficacy in the microvascular space, is shown to have beneficial effects on the kidney, which has an extensive microvascular network. OBJECTIVE: We aimed to evaluate the effect of iloprost treatment on kidney functions in patients with critical limb ischemia. METHODS: Forty-eight patients with critical limb ischemia who were not suitable for revascularization and who were treated with iloprost were evaluated prospectively in our clinic between September 2010 and December 2012. The patients were divided into 2 groups as patients with chronic renal dysfunction (Group I) and patients with normal renal function (Group II). Urine albumin:creatinine ratio and glomerular filtration rate (GFR) calculated using serum creatinine and serum cystatin C (GFRcyc) were used to establish the presence of renal dysfunction. The decrease analgesic requirement, walking distance, reduction in ulcer diameter, the increase in ankle-brachial index, and changes in The Society of Vascular Surgery/International Society of Cardiovascular Surgery criteria were used in the evaluation of treatment response. RESULTS: Opioid analgesic requirement and decubitus pain disappeared after treatment in 58.3% (n = 28) of subjects. Walking distance increased in 66.6% (n = 32). Iloprost treatment significantly increased ankle-brachial index (P < 0.01). In Group I the levels of serum urea, creatinine, and cystatin C significantly decreased (P < 0.05), whereas GFRcyc and GFR calculated using the equation of the Chronic Kidney Disease Epidemiology Collaboration (ie, GFR expressed for specified race, sex, and serum creatinine in milligrams per deciliter) was increased significantly compared with pretreatment levels (P < 0.05). No significant change was observed in urine albumin:creatinine ratio (P > 0.05). CONCLUSIONS: The use of iloprost in critical limb ischemia can slow down the progress of early stage renal damage. GFRcyc and cystatin C, which are indicators of early stage chronic renal dysfunction, can be used for the evaluation of treatment response.

Predictive value of CHA2DS2-VASc score in radial artery occlusion after transradial coronary angiography.

Background: Radial artery occlusion is the most common complication of transradial catheterization. RAO is characterized by thrombus formation due to catheterization and endothelial damage. CHA2DS2-VASc scores are the current scoring systems used to determine the risk of thromboembolism in patients with atrial fibrillation. The aim of this study was to investigate the relationship of CHA2DS2-VASc score with radial artery occlusion. Methods: This prospectively designed study was included 500 consecutive patients who underwent coronary artery transradial catheterization for diagnostic or interventional procedures. The diagnosis of radial artery occlusion was made by palpation examination and Doppler ultrasound at the twenty-fourth hour after the procedure. Independent predictors of radial artery occlusion were determined by logistic regression analysis. Results: Radial artery occlusion was observed at a rate of 9%. The CHA2DS2-VASc score was higher in the group of the patients who developed radial artery occlusion (p < 0.001). Arterial spasm (OR: 2.76, 95% CI 1.18-6.45, p: 0.01), catheterization time (OR: 1.03, 95% CI 1.005-1.057, p: 0.01) and CHA2DS2-VASc score ≥ 3 (OR: 1.44, 95% CI 1.17-1.78, p: 0.00) as significant independent predictors of radial artery occlusion. A high CHA2DS2-VASc score was associated with the continuity of the occlusion after the treatment (OR:1.37, 95% CI 1.01-1.85, p: 0.03). Conclusions: An easily applicable CHA2DS2-VASc score of ≥3 has a predictive value for radial artery occlusion.

Utility of the gastro-laryngeal tube during transesophageal echocardiography: A prospective randomized clinical trial.

BACKGROUND: To validate the utility and performance of the gastro-laryngeal tube (GLT) in terms of cardiologist and patient satisfaction levels, incidence of and attempts at successful transesophageal echocardiography (TEE) probe placement, perioperative and postoperative hemodynamics, and adverse events related to the TEE procedure. METHODS: In this randomized prospective clinical study, forty-four patients undergoing TEE and aged 20 to 80 years old scheduled for TEE were randomly allocated to two study groups: Group SA (sedation and analgesia) and Group GLT. Cardiologist and patient satisfaction levels, TEE probe placement performance, hemodynamics, adverse events related to the TEE procedure, demographic characteristics, and TEE procedure data were recorded. RESULTS: The cardiologist satisfaction level was significantly higher in Group GLT (P = .011). The TEE probe was successfully placed at the first attempt in all the patients in Group GLT and at the first attempt in 11 patients, at the second attempt in 8 patients, and at the third attempt in 3 patients in Group SA. The TEE probe placement success was significantly higher in Group GLT (P < .001), and TEE probe placement was significantly easier in Group GLT (P < .001). There were no significant differences in patient satisfaction, heart rate, mean arterial pressure, oxygen saturation, adverse events related to the TEE procedure between the groups. CONCLUSION: The present study revealed that GLT use elicited a higher cardiologist satisfaction level and resulted in more successful and easier TEE probe placement. We thus conclude that the use of the recently developed GLT may ensure airway management safety and a comfortable TEE experience.

Comparative efficacy and life quality effects of surgical stripping, radiofrequency ablation, and cyanoacrylate embolization in patients undergoing treatment for great saphenous vein insufficiency.

OBJECTIVES: To compare traditional surgery with two minimally invasive endo-venous procedures in terms of their long-term effect on the quality of life in great saphenous vein insufficiency (GSV). METHOD: This prospective observational study included 217 patients that underwent surgical stripping (n = 62), radiofrequency ablation (n = 70), or cyanoacrylate embolization (n = 85) for the treatment of GSV insufficiency. Venous Clinical Severity Score (VCSS) assessments were made, 36-item Short-Form Health Survey (SF-36) questionnaire and Chronic Venous Insufficiency quality of life Questionnaire (CIVIQ-14) were administered, before and 1 year after the treatments. RESULTS: Surgical stripping group had significantly higher closure rates than the other groups (p < 0.05). At 12 months, decrease in VCSS scores was less pronounced in the cyanoacrylate embolization group when compared to the other two groups (p < 0.05). Improvement in CIVIQ-14 scores was better in the radiofrequency ablation group when compared to the cyanoacrylate embolization group (p < 0.05). Surgical stripping or radiofrequency ablation groups performed better on several domains of SF-36, when compared to the cyanoacrylate embolization group. CONCLUSIONS: Surgical stripping and radiofrequency ablation seem to provide a better quality of life results at one year in patients undergoing treatment for GSV insufficiency.

Impact of age on long term survival following transcatheter aortic valve implantation.

OBJECTIVE: To compare the long-term survival following transcatheter aortic valve implantation (TAVI) in an octogenarian population with that in a younger population. METHODS: This retrospective study included 274 patients that underwent TAVI for severe symptomatic aortic stenosis. The study group was divided into two age groups, as those with an age ≥ 80 years (octogenarians, n = 132), and age < 80 (younger patients, n = 142). The two groups were compared in terms of clinical outcomes and survival. In addition, significant predictors of survival were estimated. RESULTS: Non-cardiac mortality (during follow-up) (21.9% vs. 10.5%, P = 0.01) and in-hospital stroke (8.3% vs. 2.8%, P = 0.01) were more common among octogenarians. The two groups did not differ in terms of mean survival (41.0 ± 2.1 vs. 38.2 ± 2.2 months, respectively, P = 0.18). Multivariate analysis identified left ventricular ejection fraction < 35% (OR: 2.17, 95% CI: 1.17-4.03; P = 0.01), preoperative of moderate to severe mitral insufficiency (OR: 1.88, 95% CI: 1.15-3.06; P = 0.01), postoperative major and life-threating bleeding (OR: 2.49, 95% CI: 1.05-5.89; P = 0.03), and in-hospital stroke (OR: 2.29, 95% CI: 1.04-5.04; P = 0.03) as potential predictors of poor survival. CONCLUSIONS: In this study, similarly favorable survival outcomes were achieved in the elderly population as in younger patients, despite the presence of comorbid conditions. A consideration should be given to non-surgical management of severe aortic stenosis with the TAVI procedure in elderly patients, in the absence of co-existent conditions associated with shortened life expectancy.

A Case of Spontaneous Multivessel Coronary Artery Spasm That Underwent Stent Implantation Accompanying ST Segment Elevation on Inferior Electrocardiographic Leads.

Coronary artery spasm is usually defined as a focal constriction of a coronary artery segment, which is reversible, and causes myocardial ischaemia by restricting coronary blood flow. A coronary spasm may rarely compromise all three epicardial arteries simultaneously. We present a case of severe coronary spasm afflicting all coronary arteries accompanying an ST segment elevation in leads D2-D3 and aVF.

Improvements in quality of life in septuagenarians versus octogenarians undergoing trans-catheter aortic valve replacement.

BACKGROUND: Very elderly patients represent a distinct patient group in clinical setting in terms of a decision for trans-catheter aortic valve replacement (TAVR) when one considers the potential improvement in the quality of life (QoL) on one hand and the benefit to risk ratio on the other. This study aimed to compare functional and QoL outcomes of TAVR between octogenarians and septuagenarians. METHODS: This prospective cohort study included 136 elderly patients (70 to 89 years of age), who underwent transfemoral TAVR due to degenerative aortic stenosis. Patients were allocated into one of the following age groups: septuagenarians (n = 67) and octogenarians (n = 69). Preoperative and early postoperative clinical parameters were recorded. In addition, QoL of the patients was evaluated using SF-36 questionnaire preoperatively and six month postoperatively. RESULTS: Groups were similar in terms of early postoperative mortality and morbidity parameters. The mean New York Heart Association (NYHA) class improved after TAVR in both groups. In addition, all SF-36 norm-based scale and SF-36 summary scale scores improved significantly in both groups during the postoperative period. Postoperatively, physical functioning, general health and physical component summary scores were significantly better in the septuagenarian group (P = 0.02, 0.01, 0.03, respectively). CONCLUSION: Although the improvement in the QoL in terms of physical health was more marked in septuagenarians than in octogenarians, substantial benefits on the QoL and particularly on mental health seem to justify re-consideration of TAVR indications in the very elderly.

Posterior leaflet segment 2 plication in ischemic mitral regurgitation repair.

AIM: To evaluate the medium-term results of plication of posterior leaflet segment 2 in addition to ring annuloplasty in patients with functional ischemic mitral regurgitation. METHODS: The study included 136 patients who underwent mitral valve repair with plication of posterior leaflet segment 2 for ischemic mitral regurgitation between 2004 and 2012. The direction and correlation of left ventricle sphericity and tethering area were established by Pearson correlation analysis in patients with or without recurrent mitral regurgitation in the medium term. RESULTS: Medium-term survival was 91.9% and freedom from moderate or severe mitral regurgitation was 89.6%. In medium-term follow-up, transthoracic echocardiography found a significant decrease in tethering area, coaptation height, and distance between the commissures compared to the pre-surgery values (p = 0.0001 in all). The distance between the papillary muscles was reduced compared to the pre-surgery period but it was not significant (p = 0.204). Pearson correlation analysis found no significant correlation between the tethering area and left ventricle sphericity in patients without recurrent mitral regurgitation (r = 0.15, p = 0.36), a highly positive correlation (r = 0.44, p < 0.001) in patients with mild recurrent mitral regurgitation, and a moderately positive correlation (r = 0.71, p < 0.01) in patients with moderate or severe recurrent mitral regurgitation. CONCLUSIONS: The tethering area, coaptation height, and distance between the commissures decreased significantly, thus posterior leaflet segment 2 plication in addition to ring annuloplasty may be the optional procedure to ensure freedom from moderate or severe mitral regurgitation.

Atrial conduction abnormalities in patients with psoriasis vulgaris.

BACKGROUND: Psoriasis vulgaris is one of the most common chronic inflammatory skin disorders. Patients with psoriasis are at risk of developing atrial fibrillation (AF). The electromechanical delay (EMD) is the time interval from the onset of the P wave on surface electrocardiography (ECG) to the beginning of the A wave. Prolonged atrial EMD is an independent risk factor for the development of AF. AIM: This study investigated the intra- and interatrial EMD in patients with psoriasis. METHODS: This study included 85 adults with psoriasis vulgaris (Group 1) and 46 age- and sex-matched healthy individuals (Group 2). ECGs were obtained from all subjects, and atrial EMD variables were calculated. Results are reported as means ± standard deviations and percentages. Continuous variables were analysed using Student's t-test. A p-value < 0.05 was considered statistically significant. RESULTS: Interatrial electromechanical delay (IA-EMD) and intra-left atrial electromechanical delay (ILA-EMD) were significantly longer in the psoriasis group compared with controls. A correlation analysis between psoriasis severity (PASI score) and the atrial conduction parameters revealed a significant positive correlation between PASI and IA-EMD (r = 0.261, p < 0.001). In addition, there was a positive correlation between high-sensitivity C-reactive protein (hsCRP) and IA-EMD (p = 0.022). CONCLUSIONS: The atrial conduction time was longer in patients with psoriasis vulgaris and it correlated with the severity of disease and hsCRP. Since the association between delayed conduction and AF is known, the measurement of intra-atrial conduction times could be a practical tool to estimate the AF risk in these patients.

Single coronary artery anomaly causing ischemic mitral insufficiency.

Single coronary artery anomaly is rarely seen, and although it can present with sudden death, chest pain, arrhythmia, myocardial infarction, or congestive heart failure, it can also be asymptomatic. We describe the case of a 58-year-old man with single coronary artery anomaly in whom the coronary artery stemmed from the left coronary sinus and caused ischemic mitral insufficiency due to left anterior descending artery stenosis. He underwent successful mitral valve repair and coronary bypass.

Endovascular therapy of acute ischaemic stroke by interventional cardiologists: single-centre experience from Turkey.

AIMS: We report our single-centre experience with the Solitaire AB self-expanding retrievable stent system in patients with acute ischaemic stroke. METHODS AND RESULTS: Demographic, clinical, and angiographic findings of thirty-eight consecutive patients with acute ischaemic stroke who underwent mechanical thrombectomy were evaluated retrospectively. The mean initial National Institutes of Health Stroke Scale (NIHSS) score was 17.8±4.6. Nearly half of the patients had a middle cerebral artery (MCA) occlusion (45%). Both internal carotid artery and MCA occlusions were detected in five patients. Successful revascularisation (Thrombolysis in Cerebral Infarction [TICI] 2b and 3) was achieved in 34 of 38 (89%) patients; a TICI 3 state was observed in 24 (63%) patients. Almost three quarters of the patients (74.3%) improved by >5 points on the NIHSS at discharge, and 57.9% showed a modified Rankin Scale (mRS) score of ≤2 at 90 days. CONCLUSIONS: This single-centre experience with mechanical thrombectomy devices demonstrated that the procedure could be performed safely with high success rates by experienced interventional cardiologists in suitably equipped cathlabs.

Comparison of the health related quality of life of patients following mitral valve surgical procedures in the 6-months follow-up: a prospective study.

PURPOSE: The aim of the present study is to evaluate the health-related quality of life of the patients who underwent mitral valve repair (MvRp) and mitral valve replacement (MVR). METHODS: Within the scope of this prospective study design, 56 patients who had mitral valve operation between the years of 2011-2012 were enrolled in the study. 24 (42.8%) of these patients had MVR while 32 (57.1%) of them had MvRp. The health-related quality of life was evaluated according to the Turkey norms of Short Form 36 Quality-Of-Life Measures (SF-36), which were filled in by the patients before and 6 months after the operation. Moreover, preoperative risk factors affecting the quality of life (age, gender, functional capacity, rhythm, hypertension, diabetes, applied surgical method and echocardiographic results) were investigated for all the patients (n = 56) by using independent sample t test analysis. RESULTS: When the pre and postoperative changes were compared between the two groups, it was found out that there were no significant difference between the groups in terms of restraints on physical role functioning (PR), and the social role functioning values (SF) (respectively; p = 0.097, p = 0.105). However, in the comparison of pre-/postoperative changes between the groups, the changes in physical functioning (PF), bodily pain (BP), general health (GH), vitality (VT) and restraints on emotional role functioning (RE) and mental health (MH) values were found out to be significantly superior in the MvRp group than in the MVR group (respectively; p <0.01, p <0.05, p <0.01, p <0.01, p <0.05 and p <0.01). It was also confirmed that female gender, atrial fibrillation (AFR), and MVR method negatively affected the physical and mental components (respectively; p = 0.033, p = 0.003, p = 0.015). CONCLUSION: RESULTS of the SF-36 quality of life measures show that quality of life may be better in patients that have had MvRp. It should be considered that the planned surgical treatment method can affect the patient's quality of life, and this effect can indicate the success of the surgical treatment.

A rare complication of pre-Eisenmenger patent ductus arteriosus: Pulmonary artery dissection.

INTRODUCTION: Pulmonary artery dissection associated with patent ductus arteriosus is usually seen in patients with pulmonary hypertension and Eisenmenger's syndrome. This paper presents a case with pre-Eisenmenger patent ductus arteriosus complicated by pulmonary artery dissection, and explains how she was surgically treated. PRESENTATION OF CASE: The transthoracic echocardiography of a 21-year-old woman complaining of effort dyspnea revealed patent ductus arteriosus. Contrast-enhanced thoracic computed tomography scan showed patent ductus arteriosus and dissection in the main pulmonary artery extending from the edge of the patent ductus arteriosus orifice to the pulmonary valve. The patent ductus arteriosus was divided with pledgeted prolene suture and the dissected aneurysmal portion of the pulmonary artery was resected by surgery. Dacron graft interposition was applied to the main pulmonary artery. DISCUSSION: Because rupture causes cardiogenic shock and sudden death, diagnosis is rare in the living subject and pulmonary artery dissection is frequently detected in autopsy. A case with pulmonary artery dissection as a result of patent ductus arteriosus has been reported in the literature, but the patient died in the preoperative period. In our study, the patient was not diagnosed to have Eisenmenger's syndrome, but had pulmonary artery dissection, a complication arising from patent ductus arteriosus. The patient underwent curative surgery that included pulmonary artery dissection repair and closure of the patent ductus arteriosus. CONCLUSION: In addition to pulmonary artery aneurysm, pulmonary artery dissection must also be considered as a complication in cases of patent ductus arteriosus with high pulmonary artery pressure diagnosed in adulthood.
