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.

Transatrial balloon atrial septostomy to facilitate weaning off venoarterial ECMO after pulmonary endarterectomy.

Atrial septostomy has been the last resort in the management of patients with the right ventricular failure related to pulmonary hypertension before lung transplantation. In this paper, we present a simple and safe technique (transatrial approach) for balloon atrial septostomy in a patient who required central venoarterial extracorporeal membrane oxygenation after pulmonary endarterectomy.

Case Report of a Successful Pediatric Central Venovenous Extracorporeal Life Support via Right Atrium-Pulmonary Artery Cannulation for Severe Chest Trauma and Hemorrhagic Shock.

Hypoxemic arrests due to severe traumatic pulmonary injury may not respond to usual medical support. Extracorporeal life support (ECLS) can be life-saving; adequate flows are needed in this setting along with a careful choice of anticoagulation strategies to minimize bleeding. A 44 month old child, who presented with severe blunt chest trauma after being run over by a truck was resuscitated with active compressions and code medications seven times before arrival to the intensive care unit.

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.

Milrinone Attenuates Heart and Lung Remote Injury after Abdominal Aortic Cross-Clamping.

Background: Phosphodiesterase enzymes play a pivotal role in the pathogenesis of ischemia/reperfusion (IR). We examined the role of milrinone (MIL), a phosphodiesterase 3 inhibitor, on remote injury of the heart and lung after abdominal aortic cross-clamping.

Design: Experimental study.

P wave dispersion in assessment of dysrhythmia risk in patients with secundum type atrial septal defect and the effect of transcatheter or surgical closure.

Atrial dysrhythmia is an important cause of mortality and morbidity in patients with atrial septal defect. Increased P wave duration can predict the risk of atrial dysrhythmia. The aim of this study is to evaluate the risk of atrial dysrhythmia by measuring P wave dispersion, and to observe the effect of surgical and transcatheter closure.

Comparison of heat monitoring-based myocardial protection strategy with classic myocardial protection method in isolated coronary artery bypass surgery patients.

Objective: In this study, we aimed to compare patients who have a myocardial protection strategy based on myocardial temperature monitorization with those who had myocardial protection with conventional intermittent cardioplegia.

Methods: Twenty-six patients undergoing coronary artery bypass graft surgery were included into the study. Patients were prospectively grouped into two; myocardial protection based on temperature monitoring (group 1, n = 11) and those who had cardioplegia every 20 min (group 2, n = 15) during aortic cross-clamping.

Salvage pulmonary thromboembolectomy for massive pulmonary embolism in a child presented with syncope and subsequent cardiac arrest.

Pulmonary embolism is frequently under-recognised in children and, therefore, a high index of suspicion should be exerted on patients with exertional dyspnoea, presyncope/syncope and unexplained cardiopulmonary arrest. We discuss a 10-year-old previously healthy girl who presented with syncope and subsequent cardiac arrest related to massive pulmonary embolism and was salvaged successfully by emergent pulmonary embolectomy.

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.
