Incidence of Clinical Outcomes in Minimally Invasive Valvular Surgery at the Ignacio Chávez National Institute of Cardiology.

Minimally invasive cardiac valve replacement surgery (MICS) is a technique that has reported equivalent rates of mortality and reintervention when compared to conventional median sternotomy (CS). Additionally, MICS has inconsistently been reported to be associated with fewer postoperative complications, better cosmetic outcomes, and shorter hospital stays at the expense of longer surgical time, aortic clamp time, and extracorporeal circulation time. When comparing populations undergoing MICS vs CS at the Ignacio Chávez National Institute of Cardiology (INCICh), it was proven that there is a longer surgical, extracorporeal circulation, and aortic clamp durations in the MICS intervention, but no statistically significant difference in global mortality.

[Clinical recurrence in patients with sequential bridges in coronary artery bypass grafting].

Objetivo: Comparar las tasas de recurrencia de revascularización coronaria (cirugía o intervención coronaria percutánea), nuevo evento isquémico o muerte en pacientes con puentes secuenciales y con puentes simples.

MÉtodo: Cohortes ambispectivas de pacientes sometidos a cirugía de revascularización coronaria secuencial (n = 111) o simple (n = 145) entre el 1 de enero de 2013 y el 31 de diciembre de 2017. Pacientes mayores de 18 años en un primer procedimiento de revascularización, con circulación extracorpórea.

Severe mitral valve regurgitation secondary to Libman-Sacks endocarditis.

Although uncommon, Libman-Sack endocarditis is the most characteristic cardiac manifestation of Systemic Lupus Erythematosus (SLE). It forms vegetations made of inflammatory tissue on the cardiac valves, leading them to malfunction. Here we present a case of a young woman who presented with severe mitral valve regurgitation in need for a valve replacement.

Mitral Valve Malignant Primary Tumor as a Surgical Emergency: Case Report.

Malignant primary tumors of the heart are among the most unusual forms of cancer. Cardiac malignancy accounts for about 20% of all primary cardiac tumors, with most arising from the atria and less frequently the ventricles; very unusual locations include the great vessels and the cardiac valves. A rare case is presented of a young female that arrived at the authors' emergency room in pulmonary edema and circulatory collapse secondary to a true tumor of the mitral leaflets that caused severe mitral valve stenosis.

Echocardiographic and Histologic Correlations in Patients with Severe Aortic Stenosis: Influence of Overweight and Obesity.

Background: Severe aortic stenosis (AS), leads to pathological left ventricular remodeling that may worsen with concomitant overweight and obesity (OW/O).

Methods: We aimed to prospectively analyze the impact of OW/O on ventricular remodeling in severe AS, by evaluating the percentage of intraendomyocardial fibrosis (PIEF) and the percentage of infiltrating intraendocardial lipid vacuoles (PIELV) and its relationship to global longitudinal strain (GLS) in patients with OW/O.

Results: 44 patients with severe AS were included, 13 non-obese (29%) and 31 OW/O (71%), all of them with left ventricular ejection fraction ≥ 55%.

Type B Aortic Dissection Repair Using a Thoraflex Hybrid Prosthesis in a Complex Aortic Arch Anatomy.

Thoracic endovascular aortic repair (TEVAR) is recognized as an attractive option to treat complicated Type B aortic dissection. Nevertheless, TEVAR is not always technically possible. We report the case of a 53-year-old male with complicated Type B aortic dissection, in the setting of a complex anomalous aortic arch anatomy with an aneurysmal aberrant right subclavian artery.

[The cardiovascular surgeon and the Syntax score].

The Syntax score has been established as a tool to determine the complexity of coronary artery disease and as a guide for decision-making among coronary artery bypass surgery and percutaneous coronary intervention. The purpose of this review is to systematically examine what the Syntax score is, and how the surgeon should integrate the information in the selection and treatment of patients. We reviewed the results of the SYNTAX Trial, the clinical practice guidelines, as well as the benefits and limitations of the score.
