Objective: To evaluate the safety and efficacy of the National Institute of Cardiology (INC) bioprosthetic heart valve in humans.

Methods: Single-center study that included 341 patients who underwent single surgical aortic valve replacement with INC heart valve.

Acute Aortic Syndrome of Ascending Thoracic Aorta: Transcarotid Percutaneous Exclusion of a Ruptured Pseudoaneurysm.

Treatment of ascending aorta disease is surgical; however, some series have evaluated the effectiveness of endovascular treatment. We report the case of a patient with a ruptured pseudoaneurysm who underwent endovascular repair via the left common carotid artery. The clinical and neurological evolution was satisfactory during the in-hospital follow-up.

Asymptomatic deep vein thrombosis in critically ill COVID-19 patients despite therapeutic levels of anti-Xa activity.

• Clinical signs are not useful for detecting DVT in critically ill COVID-19 patients. • DVT occurs despite full dose anticoagulation in critically ill COVID-19 patients. • Severe COVID-19 patients present a high prevalence of bilateral DVT.

Bone Morphogenetic Protein-2 and Osteopontin Gene Expression in Epicardial Adipose Tissue from Patients with Coronary Artery Disease Is Associated with the Presence of Calcified Atherosclerotic Plaques.

Purpose: It has been proposed that the cardiovascular effects of obesity are related to epicardial adipose tissue (EAT), which seems to play an active role on the development and calcification of atherosclerotic plaques, but the mechanisms are still unknown. Therefore, the aim of this study was to determine whether the EAT expresses the genes of calcifying factors and whether such expression is associated with the body mass index (BMI) and with the presence of coronary artery calcium (CAC) in patients with coronary artery disease (CAD).

Patients And Methods: Forty-three patients with CAD were enrolled specifically for this study, and their CAC score and EAT volume were determined by computed tomography.

Outcomes of Delayed Sternal Closure in Pediatric Heart Surgery: Single-Center Experience.

Background: Delayed sternal closure (DSC) after cardiac surgery is a therapeutic option in the treatment of the severely impaired heart in pediatric cardiac surgery.

Methods: A single-center retrospective review of all bypass surgeries performed over a 10-year period (2003-2012).

Results: Of a total of 2325 patients registered in our database, the DSC group included 259 cases (11%), and the remaining 2066 cases (89%) constituted the control group (PSC).

Coronary Revascularization in Children at a Mexican Cardiac Center: Thirteen-Year Outcomes.

Background: The indications for pediatric coronary revascularization are diverse. There are a large proportion of patients with sequelae of severe inflammatory diseases such as Kawasaki disease, and other less common causes.

Methods: Retrospective review of ten pediatric patients undergoing coronary artery bypass surgery from January 2004 to December 2016.

Common Arterial Trunk Repair by Means of a Handmade Bovine Pericardial-Valved Woven Dacron Conduit.

Background: Surgical repair of common arterial trunk (CAT) by means of a homograft conduit has become a standard practice. We report our experience in the correction of this heart disease with a handmade bovine pericardial-valved woven Dacron conduit as an alternative procedure to homografts, with a focus on early, mid-term, and long-term results.

Methods: We designed a retrospective study that included 15 patients with a mean age of 1.

[Comparison between patients undergoing Fontan operation with or without cardiopulmonary bypass].

Unlabelled: Fontan operation is the final palliative stage of patients with univentricular hearts. Cardiopulmonary bypass (CPB) decreases ventricular performance and increases pulmonary artery pressures in the post operative recovery period. It seems that Fontan operation performed without CPB decreases short term morbidity and intra hospitalary length of stay.

Complicated Acute Aortic Syndromes Affecting the Descending Thoracic Aorta: Endovascular Treatment Compared With Open Repair.

Background: For patients with complicated acute thoracic aortic syndromes, endovascular treatment, when feasible, is preferred over open surgery. However, there are limited data on the long-term benefits of endovascular treatment in complicated acute aortic syndromes affecting the descending thoracic aorta.

Hypothesis: The endovascular treatment is expected to have more favorable long-term mortality and fewer late reintervention in complicated acute thoracic aortic syndromes.

[Evolution of endovascular treatment compared with medical and surgical treatment in patients with aortic syndrome type B].

Introduction: Surgical treatment is accepted as conventional treatment of patients with acute aortic syndrome associated to ischemic complications. Promising results of thoracic endovascular aortic repair (TEVAR) has expanded its indication to a variety of thoracic aorta pathologies.

Objectives: The objective of this study was to evaluate the safety and efficacy of TEVAR during the in-hospital period and at mid-term follow-up, and compare with medical and surgical treatment in patients who presented with acute aortic syndrome (AAS) type B.

[Pediatric cardiovascular surgical data base registry in México. First report].

Introduction: Current world tendency is the detection of health problems in order to offer solution alternatives by means of the development of computarized data bases.

Objective: To present the results of a computerized data base developed for the registry of pediatric cardiac surgery with the support of Asociación Mexicana de Especialistas en Cardiopatías Congénitas (AMECC, A.C.

Mexican registry of pediatric cardiac surgery. First report.

Background: Currently, there is a spreading worldwide tendency to characterize health issues and to propose alternative solutions via the creation of computerized databases. The aim of this study was to present the results in a computerized database of pediatric cardiac surgeries developed under the auspices of the Mexican Association of Specialists in Congenital Heart Diseases (Asociación Mexicana de Especialistas en Cardiopatías Congénitas A.C) and coordinated by the collegiate group of Pediatric Cardiology and Surgery as petitioned by the National Institutes of Health and High Specialty Hospitals Coordinating Commission.

Congenital heart disease in Mexico: advances of the regionalization project.

Consistent with the mission of the World Society for Pediatric and Congenital Heart Surgery to promote health care for children with congenital heart disease all around the world, a Mexican Association of Specialists in Congenital Heart Disease (abbreviated in Spanish as AMECC) was created in Mexico in 2008. Our efforts were coordinated with those of the National Health Secretary with the objective being implementation of a national plan for regionalization of care for patients with congenital heart disease. To improve our knowledge related to technologic and human resources for management of congenital heart disease, we developed a national survey.

[Changing the paradigm of congenital heart disease: from the anatomy to the molecular etiology].

Heart development consists in a group of complex and specific morfogenetic interactions, that requires the proper activity of each factor implicated in this process. Congenital heart defects (CHD) are a group of multifactorial complex diseases with environmental and genetic factors playing important roles. There is not an exact relation between molecular mechanisms and morphological defects in CHD, because in most of the cases the proper development of an anatomical structure implies the adequate function of several pathways that may depend of the action of different genes.

Endovascular treatment of type B dissection in patients with Marfan syndrome: mid-term outcomes and aortic remodeling.

Objectives: To evaluate the mid-term outcomes, and the aortic remodeling in Marfan syndrome (MFS) patients with type B dissection that were treated with endovascular repair.

Background: MFS is a relative contraindication to thoracic endovascular aortic repair (TEVAR). Mid-term aortic outcomes data in MFS after TEVAR are limited, and the occurrence of late events remains unclear.

[Scimitar syndrome in infancy].

Objective: To expose our 26 year experience in clinical management, interventional catheterization and surgical treatment of patients younger than 18 years with scimitar syndrome at the National Cardiology Institute.

Material And Methods: We reviewed retrospectively all patients with scimitar syndrome in infancy between 1984 and 2010. Patients were divided in two groups: younger an older than one year at the time of the diagnosis.

Fontan Procedure at 2,240 m Above Sea Level.

The modified Fontan procedure represents the final stage of reconstructive surgery for most patients with functionally univentricular hearts. Although outcomes following Fontan procedures performed at sea level are widely reported, less has been documented and reported concerning outcomes in regions at high altitude. To clarify the main features involved, we present our institutional experience with Fontan operations performed in Mexico city (2,240 m above the sea level), with an emphasis on historical evolution of treatment.

[Tetralogy of Fallot with pulmonary atresia. Morphopathology and surgical anatomy].

The morphopathology of tetralogy of Fallot with pulmonary atresia is detailed as a spectrum of variations which is the foundation to highlight the surgical anatomy of this cardiopathy and it is the embryological basis which determines its structure. Thirty five hearts were studied with the methodology of the segmental sequential system. The atrial situs, the connections between the cardiac chambers and between the right ventricle and the arterial pulmonary vasculature were determined.

[Congenital heart disease in Mexico. Regionalization proposal].

Congenital cardiopathies are the most frequent congenital malformations. Reports of its prevalence around the world range from 2.1 to 12.

Anatomic diagnosis of congenital heart disease. A practical approach based on the sequentiality principle.

Based on the sequentiality principle, this review proposes a practical method that allows the systematization of the anatomic diagnosis of congenital heart disease. We emphasize the need to use sequential connection between the different cardiac segments: atria, ventricles and great arteries. Five ordered steps are defined, which include determination of atrial situs and of the connection features between the ventricles and the great arteries.

Surgical repair of congenital mitral valve malformations.

Surgical development of mitral valve repair techniques in pediatric patients has been slow because of the great variety in the presentation of congenital mitral valve malformations and the still unknown growing effect over the complex mitral valve apparatus. The aim of this study is to review our early an mid-term institutional outcomes in surgical repair of congenital mitral valve malformations. We studied retrospectively 14 patients with surgical repair of congenital mitral valve malformations in a 5 year period.
