Surgical treatment of a giant hydatid cyst in the interventricular septum.

The surgical procedure detailed in this case report focuses on the treatment of a large cardiac hydatid cyst located in the intraventricular septum. The surgical intervention comprised a comprehensive approach involving a median sternotomy and cardiopulmonary bypass. A localized mass below the tricuspid valve at the basal region of the interventricular septum was revealed.

Comparison of Bretschneider HTK and Blood Cardioplegia (4:1): A Prospective Randomized Study.

Background: We compared the effect of intermittent blood and histidine-tryptophan-ketoglutarate (HTK) solution of Bretschneider on myocardial histopathology and perioperative outcome.

Methods: Forty adult cardiac surgery patients were grouped into two ( = 20 for each): (1) Intermittent blood cardioplegia (IBC): had repeated cold 4:1 blood cardioplegia and (2) HTK: had a single dose of cold HTK for cardioprotection. Creatine kinase (CK)-MB, Troponin-I (cTn-I), pH, and lactate were studied in coronary sinus blood before and after aortic cross-clamping (AXC) and systemic blood at postoperative 6, 24, and 48 hours.

Mid-term results of surgical interventions of high-grade vena cava tumor thrombus.

Background: This study aims to investigate whether the coexistence of advanced renal cell carcinoma and inferior vena cava tumor thrombus could be treated with a multidisciplinary approach and teamwork and to evaluate early and mid-term results.

Methods: Between January 2017 and December 2020, a total of 33 patients (28 males, 5 females; mean age: 55.8±13.

Pulmonary artery sarcoma treated with pulmonary endarterectomy and leaflet reconstruction using Ozaki technique.

Pulmonary arterial intimal sarcomas (PAIS) are rare malignancies with a poor prognosis. Sarcomas present with signs and symptoms mimicking pulmonary thromboembolic disease, delaying the diagnosis. We present a 29-year-old male patient diagnosed with PAIS in the right and main pulmonary arteries extending to the left pulmonary leaflet.

Surgical treatment of massive pulmonary thromboembolism due to renal cell carcinoma.

While renal cell carcinomas frequently invade the renal vein and inferior vena cava, the right atrial extension or formation of bilateral pulmonary massive embolism is quite unusual. A 65-year-old male patient underwent bilateral pulmonary tumor endarterectomy and total thrombectomy of the inferior vena cava combined with left nephrectomy under total circulatory arrest with antegrade cerebral perfusion. Both mediastinal and abdominal approaches facilitated the complete removal of the caval thrombus under the guidance of transesophageal echocardiography.

Subclavian flap aortoplasty for infant coarctation of the aorta.

Aortic resection with an extended end-to-end anastomosis is the surgical gold standard treatment for infant aortic coarctation and has excellent early and long-term outcomes.  Subclavian flap aortoplasty is an alternative surgical technique that offers some advantages because there is no need to do extensive dissection and mobilization of the aortic arch and descending aorta as required in an extended end-to-end anastomosis.  This video tutorial illustrates the technical aspects of subclavian flap aortoplasty in an infant.

Histopathologic evaluation of saphenous vein grafts in patients with type II diabetes mellitus undergoing coronary artery bypass grafting.

Introduction: Diabetes Mellitus (DM) has been known to be a risk factor for the development of more severe form of saphenous vein graft disease after coronary artery bypass grafting (CABG). We aimed to evaluate the impact of type II-DM on histopathological features of great saphenous vein grafts of patients undergoing CABG.

Patients And Methods: Forty consecutive patients undergoing elective CABG were enrolled into the study.

Repair of Scimitar syndrome using an extracardiac conduit in pediatric patients: Report of two patients.

Scimitar syndrome (SS) can be repaired by different surgical techniques including direct implantation, intracardiac rerouting, and pericardial channel to direct the Scimitar vein (SV) to the left atrium. The presence of several anatomical variations such as remote infradiaphragmatic drainage of the SV and abnormal situs makes the repair more challenging with conventional repair techniques. In this paper, we present our experience in using an extracardiac-ringed polytetrafluoroethylene conduit in two pediatric patients (14 months and 2 years old) with SS.

The Perceval Sutureless Valve in Aortic Root Reoperation.

The case is reported of a 62-year-old man with severe aortic regurgitation that was related to failed prior valve-sparing ascending aortic aneurysm repair, and who was successfully treated with a Perceval Sutureless valve.

Correction of cortriatriatum sinister with classical Raghib's complex using an extracardiac conduit.

We present a 32-year-old patient with cortriatriatum sinister with Raghib's complex (a left persistent superior vena cava draining into the left atrium with an absent coronary sinus and an atrial septal defect [ASD]) who underwent successful surgical correction with excision of the cortriatriatum, closure of the ASD, and establishing the drainage of the persistent left superior vena cava to the right atrium via interposition of an extracardiac 13-mm ringed polytetrafluoroethylene conduit.

The preventive and curative effects of melatonin against abdominal aortic aneurysm in rats.

Objective: Oxygen free radicals are important components involved in the histopathologic tissue alterations observed during abdominal aortic aneurysms (AAAs). This study examined whether melatonin has protective or therapeutic effects against AAAs.

Methods: Sprague-Dawley rats were divided into four groups.

Disseminated Peripheral Mycotic Aneurysms and Septic Embolizations Related to an Infected Stent Deployed for Restenosis of Surgically Repaired Supravalvular Aortic Stenosis.

Percutaneous treatment of supravalvular aortic stenosis (SVAS) by means of balloon dilation and stent deployment has been rarely reported in the literature. In this report, we present the case of a patient with mycotic aneurysms, disseminated peripheral and cerebral septic embolizations, and infected vegetations associated with a stent that had previously been deployed to treat restenosis of surgically corrected SVAS in the infancy.

Polymorphisms of MMP9 and TIMP2 in Patients with Varicose Veins.

Background: Genetic predisposition is a suggested risk factor in the etiology of varicose veins. The matrix metalloproteinase (MMP) family degrades extracellular matrix (ECM) and may lead to disturbances in vein wall structure. The activity of MMPs in the ECM are controlled by specific tissue inhibitors of MMPs (TIMP).

Large lipomatous hypertrophy of the interventricular septum.

We present the case of a 58-year-old woman who had large lipomatous hypertrophy of the interventricular septum, a condition that is reported very infrequently. Preoperative cardiac magnetic resonance images revealed an inhomogeneous, infiltrating mass that was suppressed in fat-suppression mode. The extensive mass was causing right ventricular dysfunction, so we excised it through a right ventricular approach.

Veno-venous extracorporal membrane oxygenation in a deeply hypoxemic infant with persistent air leakages: The first successful pediatric veno-venous extracorporeal membrane oxygenation case report in Turkey.

In severe respiratory failure, extracorporal membrane oxygenation support is life-saving, but it has been started to be used in pediatric intensive care units in our country very recently. Here, we present a five-month old girl who developed acute respiratory distress and air leakages following removal of a foreign body obstructing the airway. Mechanical ventilation only increased the air leaks and - despite drainage-resulted in hypoxemia, acidosis and finally cardiopulmonary arrest.

Direct transapical implantation of an endocardial pacing lead to the left ventricle: an alternate pacing site after tricuspid valve replacement.

In this paper, we report an alternative approach for implantation of ventricular pacing lead for complete atrioventricular block after tricuspid valve replacement.

Topsy-turvy heart: a very rare congenital rotational heart disease with tracheobronchial anomalies.

The topsy-turvy heart is characterized by a global 90°clockwise rotation around the heart's long axis. This rotation displaces all basal great arteries inferiorly and posteriorly, resulting in elongation and stretching of the brachiocephalic arteries and the bronchi. To date, reports of only four living cases have been published in the literature.

Comparison of new technology integrated and nonintegrated arterial filters used in cardiopulmonary bypass surgery: a randomized, prospective, and single blind study.

Background: Innovative cardiopulmonary bypass (CPB) settings have been developed in order to integrate the concepts of "surface-coating," "blood-filtration," and "miniaturization."

Objectives: To compare integrated and nonintegrated arterial line filters in terms of peri- and postoperative clinical variables, inflammatory response, and transfusion needs.

Material And Methods: Thirty-six patients who underwent coronary bypass surgery were randomized into integrated (Group In) and nonintegrated arterial line filter (Group NIn) groups.

The effects of pulsatile cardiopulmonary bypass on acute kidney injury.

Purpose: Protective effect of pulsatile flow cardiopulmonary bypass (CPB) on the occurrence of acute renal injury is still a matter of debate. The objective of this study was to compare the effects of pulsatile and non-pulsatile cardiopulmonary bypass on kidneys using Urinary neutrophil gelatinase-associated lipocalin (NGAL) and interleukin-18 (IL-18) as the markers of renal injury.

Methods: 85 consecutive patients with normal preoperative renal function were prospectively enrolled in the study.

Effect of body mass index on early morbidity and mortality after isolated coronary artery bypass graft surgery.

Objectives: Obesity is a risk factor for morbidity after isolated coronary artery bypass grafting. This study aimed to analyze the sole effect of body mass index (BMI) on early morbidity and mortality in patients after isolated coronary artery bypass grafting.

Design: This study was retrospective and used an electronic database of anesthesia information management.

Cardiac tamponade from a giant thymoma: case report.

Thymoma, the most common neoplasm of the anterior mediastinum especially in adults, accounts for 20-25% of all mediastinal tumors and 50% of anterior mediastinal masses. These tumors are routinely asymptomatic for prolonged periods of time. Pericardial tamponade is a very rare initial manifestation of a thymoma.

Autologous right pulmonary artery tissue for repair of left pulmonary artery originating from left patent ductus arteriosus in a patient with tetralogy of Fallot and absent pulmonary valve.

Left pulmonary artery (PA) originating from patent ductus arteriosus is an exceptionally rare variant of tetralogy of Fallot with absent pulmonary valve. We described an alternative technique for the repair of discontinuous left PA with the use of the redundant pulmonary artery tissue as material for the conduit in a 3-year-old boy.

Testicular germ cell tumor metastatic to the right atrium.

We describe a right atrial metastasis of a testicular germ cell tumor, which was successfully removed from the tricuspid valve and subvalvular apparatus without the need for valve replacement. 

Aortic root aneurysm after off-pump reduction aortoplasty.

We present a patient with aortic root aneurysm and severe aortic regurgitation who had a previous off-pump reduction ascending aortoplasty and external wrapping with concomitant coronary bypass grafting. Preliminary aortic dissection and erosion of the aortic intima were detected during the operation. This complication warrants the re-evaluation of the indications for reduction ascending aortoplasty and emphasizes the necessity for close follow-up.
