Giant Left Anterior Descending Coronary Artery Aneurysm in a Patient with Behçet's Disease.

Coronary artery involvement is quite rare in the course of Behçet's disease. Complications secondary to coronary artery aneurysms, including rupture, dissection, and myocardial ischemia, may be fatal. In young patients without cardiovascular risk factors, systemic inflammatory vasculitis syndromes should be investigated in case of acute coronary syndrome secondary to dilated coronary arteries. In this report, we present our management strategy in a 31-year-old male patient with Bechet's disease.

Intracardiac masses: Single center experience within 12 years: I-MASS Study.

Objective: The aim of this cross-sectional, retrospective, descriptive study was to review and classify cardiac masses systematically and to determine their frequencies. Methods: The medical records of 64,862 consecutive patients were investigated within 12 years. Every patient with a cardiac mass imaged by transthoracic echocardiography (TTE) and confirmed with an advanced imaging modality such as transesophageal echocardiography (TEE), computed tomography (CT) and/or cardiac magnetic resonance imaging (CMR) was included. Acute coronary syndromes triggering thrombus formation, vegetations, intracardiac device and catheter related thrombi were excluded. Results: Data demonstrated 127 (0.195%) intracardiac masses consisting of 33 (0.050%) primary benign, 3 (0.004%) primary malignant, 20 (0.030%) secondary tumors, 3 (0.004%) hydatid cysts and 68 (0.104%) thrombi respectively. The majority of primary cardiac tumors were benign (91.67%), predominantly myxomas (78.79%), and the less malignant (8.33%). Secondary cardiac tumors were common than the primary malignant tumors (20:3), with male dominancy (55%), lymphoma and lung cancers were the most frequent. Intracardiac thrombi was the majority of the cardiac masses, thrombi accompanying malignancies were in the first range (n = 17, 25%), followed by autoimmune diseases (n = 13, 19.12%) and ischemic heart disease with low ejection fraction (n = 12, 17.65%). Conclusions: This retrospective analysis identified 127 patients with cardiac masses. The majority of benign tumors were myxoma, the most common tumors that metastasized to the heart were lymphoma and lung cancers, and the thrombi associated with malignancies and autoimmune diseases were the most frequent.

Off-pump ascending aorta or aortic arch to descending aorta bypass with a pericardial roll for the treatment of critically ill infants with interrupted aortic arch.

AIM: Standard surgical treatment of the interrupted aortic arch with the use of cardiopulmonary bypass is risky especially in critically ill babies. In this manuscript, we present the results of off-pump pericardial roll bypass for the treatment of aortic interruption. MATERIAL AND METHODS: The technique was applied in nine critically ill infants between July 2011 and December 2019. Data were reviewed retrospectively. There were four girls and five boys. The types of the interruption were type B in six cases and type A in three babies. Additional cardiovascular anomalies were ventricular septal defect in all, atrial septal defect or patent foramen ovale in all, single-ventricle pathologies in two and bicuspid aortic valve in three cases. All the patients were in critical situations such as intubated, having symptoms of infection, congestive heart failure or ischaemia and malperfusion leading visceral organ dysfunction. RESULTS: All patients underwent off-pump ascending aorta or aortic arch to descending aorta bypass with a pericardial roll. Post-operative early mortality occurred in one patient with severe mitral regurgitation due to cardio-septic shock. One patient who had single-ventricle pathology underwent bidirectional Glenn and was lost on the post-operative 26th day due to sepsis 2 years after operation. Two patients presented with dilatation of the pericardial tube 18 and 24 months after the operations and one underwent reconstruction of the neo-arch. The remaining patients are asymptomatic, active and within normal limits of body and mental growth. CONCLUSION: Treatment of interrupted aortic arch with a bypass with an autologous pericardial roll treated with gluteraldehyde without cardiopulmonary bypass seems a safe and reliable technique especially for the treatment of critically ill infants.

Giant Aneurysm of the Ascending Aorta Requiring Emergency Repair in a Newborn Baby.

Congenital aneurysm of the ascending aorta is a rare cardiovascular pathology and usually associated with well-known connective tissue disorders. We present an idiopathic ascending aortic aneurysm extending to the aortic arch in an antenatally diagnosed newborn who required immediate surgical treatment due to the rapid progression of aneurysm size at the age of 1 day.

Surgical Resection Of Thoracic Aortic Aneurysms In Wiskott-Aldrich Syndrome.

Aortic aneurysms are a rare condition in children. Wiskott-Aldrich syndrome is a primary immunodeficiency characterized by infections, thrombocytopenia, and eczema. Aortitis and aneurysm formation seem to be progressive in patients with Wiskott-Aldrich syndrome. The risk of death from aneurysmal rupture in patients with Wiskott-Aldrich syndrome is high and surgery is required for resection of aneurysms. We report a case where a successful resection of a descending thoracic aneurysm. We present a-12 year-old child with this syndrome who underwent a one-stage descending aortic aneurysm repair under continuous visceral perfusion.Histologic examination showed the presence of an aortitis withgranulomatous inflammatory response and multinucleated cells.

Glenn Procedure in a Baby with Single Pulmonary Artery and Single Lung.

Glenn followed by Fontan are still the main two procedures for the treatment of patients with single ventricle. Some patients may be challenging due to unfavorable cardiopulmonary anatomy. In this report, we present Glenn shunt procedure in a patient with single pulmonary artery and congenitally agenetic lung.

The effect of two different glycemic management protocols on postoperative cognitive dysfunction in coronary artery bypass surgery / Efeito de dois protocolos de controle glicêmico diferentes sobre a disfunção cognitiva após cirurgia de revascularização do miocárdio

Abstract Introduction: Postoperative cognitive dysfunction (POCD) is an adverse outcome of surgery that is more common after open heart procedures. The aim of this study is to investigate the role of tightly controlled blood glucose levels during coronary artery surgery on early and late cognitive decline. Methods: 40 patients older than 50 years undergoing elective coronary surgery were randomized into two groups. In the "Tight Control" group (GI), the glycemia was maintained between 80 and 120 mg dL-1 while in the "Liberal" group (GII), it ranged between 80-180 mg dL-1. A neuropsychological test battery was performed three times: baseline before surgery and follow-up first and 12th weeks, postoperatively. POCD was defined as a drop of one standard deviation from baseline on two or more tests. Results: At the postoperative first week, neurocognitive tests showed that 10 patients in the GI and 11 patients in GII had POCD. The incidence of early POCD was similar between groups. However the late assessment revealed that cognitive dysfunction persisted in five patients in the GII whereas none was rated as cognitively impaired in GI (p = 0.047). Conclusion: We suggest that tight perioperative glycemic control in coronary surgery may play a role in preventing persistent cognitive impairment.

Resumo Introdução: A disfunção cognitiva pós-operatória (DCPO) é um resultado adverso cirúrgico que é mais comum após cirurgias cardíacas abertas. O objetivo deste estudo foi investigar o papel dos níveis de glicose no sangue rigorosamente controlados durante a cirurgia coronariana no declínio cognitivo precoce e tardio. Métodos: Foram randomizados em dois grupos 40 pacientes acima de 50 anos e submetidos à cirurgia coronariana eletiva. No grupo "controle rigoroso" (GI), a glicemia foi mantida entre 80-120 mg.dL-1; enquanto no grupo "liberal" (GII), variou entre 80-180 mg.dL-1. A bateria de testes neuropsicológicos foi feita três vezes: fase basal, antes da cirurgia e na primeira e 12ª semana de acompanhamento no pós-operatório. DCPO foi definida como uma queda de um desvio padrão da fase basal em dois ou mais testes. Resultados: Na primeira semana de pós-operatório, os testes neurocognitivos mostraram que 10 pacientes no GI e 11 pacientes no GII apresentaram DCPO. A incidência de DCPO precoce foi semelhante entre os grupos. No entanto, a avaliação tardia revelou que a disfunção cognitiva persistiu em cinco pacientes no GII, enquanto nenhum paciente foi classificado como cognitivamente prejudicado no GI (p = 0,047). Conclusão: Sugerimos que o controle glicêmico rigoroso no perioperatório de cirurgia coronariana pode desempenhar um papel na prevenção da deterioração cognitiva persistente.

The role of Porphyromonas gingivalis in the development of atherosclerosis and its relationship with fim A genotype.

BACKGROUND: Porphyromonas gingivalis, a major periodontal pathogen, is gaining increasing attention for its possible association with atherosclerosis. Its fimbriae are classified into six genotypes (Types I-V, Ib) based on the diversity of the fim A genes encoding the fimbrial subunits. In this study, fim A genotype's distribution of P. gingivalis was analyzed in atherosclerotic plaque specimens. METHODS: A total of 50 atherosclerotic plaque specimens and 50 non-atherosclerotic, post stenotic aneurysm specimens were collected from patients undergoing cardiovascular surgery. Bacterial DNA was also extracted from each specimen, as real-time PCR was carried out with P. gingivalis-specific primer sets. The positive specimens of P. gingivalis were further analyzed to discriminate the fim A genotype using real-time and nested PCR methods. RESULTS: P. gingivalis was detected only in one atherosclerotic plaque; however, the genotype was nontypable in this specimen. CONCLUSIONS: We state that it is not easy to show a significant relationship between P. gingivalis, its fim A genotype, and atherosclerosis. We suggest that new extended studies based especially upon the quantitave determination of P. gingivalis and its genotype distribution on atherosclerotic specimens are needed to show an evident relationship between atherosclerosis and P. gingivalis.

Pressure-controlled mechanical ventilation is more advantageous in the follow-up of patients with chronic obstructive pulmonary disease after open heart surgery.

OBJECTIVE: Cardiopulmonary bypass deteriorates pulmonary functions to a certain extent. Patients with chronic obstructive pulmonary disease (COPD) are associated with increased mortality and morbidity risks in the postoperative period of open-heart surgery. In this study we compared 2 different mechanical ventilation modes, pressure-controlled ventilation (PCV) and volume-controlled ventilation (VCV), in this particular patient population. PATIENTS AND METHODS: Forty patients with severe COPD were assigned to 1 of 2 groups and enrolled to receive PCV or VCV in the postoperative period. Arterial blood gases, respiratory parameters, and intensive care unit and hospital stays were compared between the 2 groups. RESULTS: Maximum airway pressure was higher in the VCV group. Pulmonary compliance was lower in the VCV group and minute ventilation was significantly lower in the group ventilated with PCV mode. The respiratory index was increased in the PCV group compared with the VCV group and with preoperative findings. Duration of mechanical ventilation was significantly shorter with PCV; however, intensive care unit and hospital stays did not differ. CONCLUSION: There is not a single widely accepted and established mode of ventilation for patients with COPD undergoing open-heart surgery. Our modest experience indicated promising results with PCV mode; however, further studies are warranted.

Extracardiac off-pump fontan completion for single ventricle with dextrocardia.

Extracardiac off-pump is reported to result in better early hemodynamics and shorter mechanical ventilation periods. We present a case report of extracardiac off-pump Fontan in a 5-year-old girl with single ventricle and dextrocardia.

Transcaval invasion of right atrium by thymoma: resection via transient cava-pulmonary shunt.

Transcaval extension of the thymoma to the right atrium has very rarely been reported, and cardiopulmonary bypass is recommended for successful resection. An invasive thymoma with intravascular invasion of the superior vena cava, and the left innominate vein extending into the right atrium was presented. Intra-atrial extension was resected through a transient external shunt from the inferior vena cava to the main pulmonary artery. We discussed the feasibility of this surgical technique and possible advantages of cardiopulmonary bypass avoidance.

Aorta after stent grafting for mycotic aneurysm.

Endovascular stent grafting is applied for the treatment of different aortic pathologies in the current medical era. It may be lifesaving in patients with comorbidities and virtually inoperable when adopting conventional techniques. This manuscript reports on a 40-year-old patient, who was previously treated for a mycotic saccular aneurysm at the aortic arch and who presented with a descending aortic rupture at the mid-term follow-up. The descending aortic rupture was also managed successfully by endovascular measures.

Modified Nikaidoh procedure in a patient with transposition of the great arteries, ventricular septal defect, and left ventricular outflow tract obstruction with unusual coronary anatomy.

The Rastelli operation has been the most common procedure for the repair of transposition of the great arteries with ventricular septal defect and left ventricular outflow tract obstruction. A relatively recent approach is the Nikaidoh procedure. Despite the fact that it seems promising, the operation lacks long-term follow-up data. It has been postulated that patients with anomalous coronary arteries are high-risk candidates for the Nikaidoh procedure and its modifications. In this report, we present the case of a patient with transposition of the great arteries with remote restrictive ventricular septal defect and left ventricular outflow tract obstruction with coronary anomaly - with the right coronary artery originating from the left anterior descending coronary artery and crossing the right ventricular outflow tract - who underwent successful modified Nikaidoh operation.

Bilateral PDA in a patient with VSD and pulmonary atresia.

Patent ductus arteriosus is one of the most common congenital cardiac pathologies, besides patency of ductus may be somewhat vital for various congenital cardiac defects, otherwise death is inevitable. Anatomically, ductus is single and located between the descending aorta and the pulmonary artery. The review of the literature reveals presence of more than one ductus arteriosi in sporadic cases, most commonly associated with aortic arch anomalies. In this report, we present a nine-month-old baby with the diagnosis of ventricular septal defect (VSD), pulmonary atresia (PA), nonconfluent pulmonary arteries, and bilateral patent ductus arteriosi. He underwent a successful pulmonary reconstruction and central-shunt operation with modified aortopulmonary window technique without cardiopulmonary bypass. This is a very rare case with double ductus arteriosi associated with VSD, PA, and nonconfluent pulmonary arteries.
