Background
The lack of evidence on complications using mitral valve approaches leaves the choice of risk exposure to the surgeon’s preference, based on individual experience, speed, ease, and quality of exposure.
Methods
The present study analysed patients undergoing mitral valve surgery using a superior transseptal approach or a left-atrial appro...
Superior vena cava syndrome (SVCS) is an entity that has become more frequent due to the increasing use of indwelling central venous catheters. Surgical management is considered in patients with extensive venous thrombosis and when endovascular therapy is not feasible. The use of superficial femoral vein is an excellent technique for reconstruction...
A 5-year-old child, weighing 15 kg, with three previous sternotomies, presented with right heart failure due to severe stenosis and regurgitation of the bioprosthetic tricuspid valve. A percutaneous tricuspid valve-in-valve procedure with an Edwards S3 valve was ofered for compassionate use, performed with no complications and with a significant cl...
Introduction
Given the anatomical variations of tetralogy of Fallot (TOF), different surgical techniques can be used to achieve correction. Transannular patches are the most commonly used technique; they are associated with right ventricular dysfunction, the incidence of which can be reduced through pulmonary valve preservation.

Resumen
La disección aórtica aguda (DAA) es una emergencia cardiovascular con una mortalidad operatoria hasta del 30%. Se estima que cerca del 80% de los pacientes mueren antes de llegar a un hospital, y la mortalidad sin intervención quirúrgica alcanza el 60%. La optimización de estos resultados depende de un trabajo mancomunado entre los equipos...

We describe the case of a 77-year-o...
Objective: Low-volume centers might be reluctant to perform minimally invasive mitral valve repair (Mini-MVr) due to the initial learning curve involved, rates of repair, and outcomes. The objective of this study was to assess the learning process and outcomes of Mini-MVr in a low-volume center and compare the results with the conventional techniqu...
Purpose:
The use of open hybrid stent graft systems (E-VITA) has become an excellent option for the treatment of complex aortic aneurysm and aortic dissections. However, its use in Latin America is unpopular and the established practice is to perform just an ascending aorta limited repair.
Methods:
Since February 2018, we began to use the E-VITA...
Purpose
Transcatheter aortic valve replacement (TAVR) is an acceptable alternative to surgery in patients with severe aortic stenosis. Studies have suggested that patients with a reduced left ventricular ejection fraction (LVEF) and low aortic valve gradient have worse short and long-term outcomes.
Methods
Between 2009 and 2017, 112 patients under...
Purpose :
This study shows how low-volume centers can achieve results in mitral valve repair (MVr) surgery comparable to those reported by referral centers. It compares outcomes of MVr using resection versus noresection techniques, tendencies, and rates of repair.
Methods:
Between 2004 and 2017, 200 patients underwent MVr for degenerative mitral va...
Purpose
Since minimally invasive mitral valve repair (Mini-MVr) technique was introduced, it has become a routine approach to mitral valve disease. However, surgeons from low-volume centers might be reluctant to adopt this technique due to the initial learning curve involved.
Methods
Between 2004 and 2017, 200 patients underwent a mitral valve rep...
Purpose
Transcatheter aortic valve replacement (TAVR) is a global acceptable alternative to surgery in patients with severe aortic stenosis. However, short and long-term TAVR results in Latin America remain unknown.
Methods
Between 2009 and 2017, 112 patients underwent a TAVR due to severe aortic stenosis at Fundación Cardioinfantil-Instituto de C...
Background:
The approach to coarctation of the aorta with hypoplastic aortic arch is controversial. We evaluated the outcomes in patients with coarctation of the aorta with or without hypoplastic aortic arch operated through a posterior left lateral thoracotomy.
Methods:
A retrospective cohort of patients with aortic coarctation, who underwent repa...
Background
Recent evidence has showed us that quality of mitral valve repair is strongly related to volume. However, this study shows how low-volume centers can achieve results in mitral valve repair surgery comparable to those reported by referral centers. It compares outcomes of mitral valve repair using resection versus noresection techniques, t...
Background:
Mechanical circulatory support (MCS) represents an effective urgent therapy for patients with cardiac arrest or end-stage cardiac failure. However, its use in developing countries as a bridge therapy remains controversial due to costs and limited duration. This study presents five patients who underwent MSC as bridge therapy for heart...
Abstract for Presentation on Demand
The anatomical location of adipose tissue might have direct implications for its functionality and risk of cardiovascular disease. Adipose tissue surrounding blood vessels may be thermogenically more active in specific areas of the body, releasing substances that regulate vascular metabolism. In humans, the phenotypic characteristics of adipose tis...
Adipose tissue can affect the metabolic control of the cardiovascular system, and its anatomic location can affect the vascular function differently. In this study, biochemical and phenotypical characteristics of adipose tissue from periaortic fat were evaluated. Periaortic and subcutaneous adipose tissues were obtained from areas surrounding the a...

... Theoretically, the relative hypoxemia induced by low partial pressure of inhaled oxygen that occurs with rising elevation could increase PVR and therefore increase the risk of Fontan failure [4,24,25]. As a result, it has become routine at some centers practicing at higher altitudes (including our own which sits at around 1604 m above sea-level) to place fenestrations in nearly all patients undergoing the procedure [26,27]. To date, there have been no prospective studies directly comparing outcomes between fenestrated and non-fenestrated patients at altitude. ...

... It is suggested that limiting the processes involved in general anesthesia such as induction, orotracheal intubation, and positive pressure ventilation can lead to better hemodynamic stability and minimize the use of vasopressors and inotropes post operatively. 12 Complications involving the aorta, AV annulus, or LV are rare. Aortic dissection after TAVI is rare, occurring at the rate of <2%, and can involve any segment of the aorta. ...

... muscles rupture and postoperative negative left ventricular remodeling could increase the risk of recurrent mitral regurgitation. [11][12][13][14] We designed and tested an innovative device characterized by a ring portion to reshape the annulus and by an intraventricular segment for leaflet or artificial chordae anchoring. It is conceived to overcome technical complexity of chordal length estimation, papillary muscle exposure, and suturing, because artificial chordae are anchored to a fixed structure. ...
... Several authors used an extended end-to-end anastomosis and had good results with low frequency of reCoAo. [16][17][18] Worth noting, all authors suggest that left thoracotomy approach and extended end-to-end anastomosis are good choice at z-score value −6 and more. 17 This strategy expects the growth of the proximal aortic arch after the distal obstruction has been removed. ...

... A nivel molecular, los preadipocitos y adipocitos blancos de diferentes regiones y cultivados en condiciones idénticas, conservan diferencias distintivas en los patrones de expresión génica; incluso después de muchas generaciones en platos de cultivo los adipocitos viscerales son diferentes a los subcutáneos 22 22 . Los autores de este artículo encontraron que los adipocitos periaórticos a nivel del tórax tienden a ser metabólicamente más activos en relación con los subcutáneos 23 . De hecho, en la medida que las personas aumentan el peso corporal la característica energética de estas células adiposas se va reduciendo 24 . ...
