Altogether 19 papers were found using the reported search, of which 5 represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated.

Dissecting intramyocardial hematoma after robotic mitral valve repair.

We report the first case of a dissecting intramyocardial hematoma discovered intraoperatively after robotic mitral valve repair, potential etiologies relevant to robotic surgery, and its successful management.

How to perform a coronary artery anastomosis in complete endoscopic fashion with robotic assistance.

Current technology in robotic surgery allows us to perform myocardial revascularization procedures in a totally endoscopic fashion. We will describe the technique of choice for left internal mammary artery to left anterior descendent artery anastomosis with the use of cardiopulmonary bypass machine. The method is efficient and there is long term follow-up showing similar patency of the graft when compared to conventional methods (when performed through sternotomy).

Atrial Fibrillation After Robotic Cardiac Surgery.

Atrial fibrillation is one of the commonest complications after cardiac surgery and it is associated with considerable morbidity and increase in mortality. Recently, robotic approach to many heart operations has become feasible and reproducible. We here investigate and review the incidence of atrial fibrillation after robotic cardiac surgery.

Mammary artery harvesting using the Da Vinci Si robotic system.

Internal mammary artery harvesting is an essential part of any coronary artery bypass operation. Totally endoscopic coronary artery bypass graft surgery has become reality in many centers as a safe and effective alternative to conventional surgery in selected patients. Internal mammary artery harvesting is the initial part of the procedure and should be performed equally safely if one wants to achieve excellence in patency rates for the bypass.

Robotically assisted totally endoscopic coronary artery bypass surgery.

Robotically assisted totally endoscopic coronary artery bypass surgery has emerged as a feasible and efficient alternative to conventional full sternotomy coronary artery bypass graft surgery in selected patients. This minimally invasive approach using the daVinci robotic system allows fine intrathoracic maneuvers and excellent view of the coronary arteries. Both on-pump and off-pump operations can be performed to treat single and multivessel disease.

Simplified frozen elephant trunk repair for acute DeBakey type I dissection.

Objective: The study objective was to describe a novel technique and assess the safety and feasibility of this initial experience for performing a modified frozen elephant trunk extended repair of acute dissection.

Use of bipolar radiofrequency for the treatment of atrial fibrillation during cardiac surgery.

Background: Atrial fibrillation with tissue ablation device through bipolar radiofrequency in conjunction with cardiac surgery has proven to be an effective method to treat this arrhythmia.

Objective: Describe the initial experience of the Instituto Nacional de Cardiologia in the surgical treatment of atrial fibrillation using bipolar radiofrequency device in patients undergoing cardiac surgery, reporting the results of postoperative follow-up of one year.

Methods: Between January 2008 and March 2009, 47 consecutive patients (36 women), with mean age of 53.

Cardiac angiosarcoma.

Despite cardiac metastases are found in about 20% of cancer deaths, the presence of primary cardiac tumors is rare. Most primary tumors are benign, and malignant tumors comprise about 15%. We report a 21-year-old man with fever, dyspnea, and hemoptysis that was diagnosed with angiosarcoma of the right atrium and pulmonary metastasis.

Cannulation tactics in upper ministernotomy for the surgical treatment of congenital heart disease.

Introduction: The present report describes the technique for "inverted L" upper ministernotomy with central canulation for the treatment of simple congenital cardiopathies and presents the initial results.

Methods: Ten patients (mean age: 7 +/- 4.2 years; mean weight 29.

Videothoracoscopy for isolated atrial fibrillation ablation through bipolar radiofrequency.

Background: The prevalence of atrial fibrillation, expenses with the healthcare system and the associated high morbidity and mortality have justified the search for new therapeutic approaches.

Objective: To evaluate the reproducibility of the surgical technique, its safety and the initial outcome of the video-assisted surgery for the isolated atrial fibrillation ablation with bipolar radiofrequency.

Methods: Ten patients (90% men) with symptomatic atrial fibrillation (50% paroxystic type) that was refractory to drug therapy, with no heart disease that required concomitant surgical treatment, were submitted to arrhythmia ablation guided by thoracoscopy from May 2007 to May 2008.

Surgical treatment of right atrial myxoma complicated with pulmonary embolism.

Myxomas are the most common type of cardiac benign tumors and most of them are located in the left atrium, followed by the right atrium. Myxomas in the right atrium may rarely embolize to the pulmonary arterial vasculature. Here, we present a case report of a patient with right atrial myxoma and massive embolism to the pulmonary arteries treated surgically with right atrial mass removal and pulmonary embolectomy.

Cardiac tamponade caused by central venous catheter in two newborns.

Cardiac tamponade secondary to the use of central venous catheter is a rare complication; however, it is potentially reversible when it is caught in time. We report two cases of cardiac tamponade that was diagnosed using a transthoracic echocardiography, followed by urgent pericardiocentesis and surgical pericardial drainage as a complication from umbilical venous catheterization. In one case, the tip of the catheter was properly placed, and in the other case, it was not.

Surgical treatment of anomalous coronary artery arising from the pulmonary artery.

Anomalous coronary arteries arising from the pulmonary trunk is a rare but potentially fatal condition. We report the clinical presentation, surgical treatment and long-term follow-up of seven surgical cases of anomalous left coronary and one case of anomalous right coronary artery arising from the pulmonary artery. Age ranged from 7 months to 13 years (average: 5.

Adult extracorporeal life support: a failed or forgotten concept?

Background: The extracorporeal membrane oxygenation (ECMO) has been used in the neonatal and childhood periods with excellent results. The adult experience has been modest with inferior immediate results. The intermediate survival, however, has been promising.

Mid-to-long term follow-up after surgical repair of atrioventricular septal defect with common atrioventricular junction and ventricular shunting associated with tetralogy of Fallot.
