[Cardiologist training in Chile and contributions from the Chilean Society of Cardiology and Cardiovascular Surgery].

The Chilean Society of Cardiology and Cardiovascular Surgery (SOCHICAR) is a scientific society whose mission is to improve the nation's cardiovascular health. Its primary goals include discussing issues affecting the specialty and engaging in various activities that support its advancement. To achieve these goals, numerous educational initiatives are undertaken for health professionals, including physicians in cardiology training programs.

Predicting Cardiovascular Rehabilitation of Patients with Coronary Artery Disease Using Transfer Feature Learning.

Cardiovascular diseases represent the leading cause of death worldwide. Thus, cardiovascular rehabilitation programs are crucial to mitigate the deaths caused by this condition each year, mainly in patients with coronary artery disease. COVID-19 was not only a challenge in this area but also an opportunity to open remote or hybrid versions of these programs, potentially reducing the number of patients who leave rehabilitation programs due to geographical/time barriers.

Average and Interindividual Effects to a Comprehensive Cardiovascular Rehabilitation Program.

Background: To describe the average effects and the interindividual variability after a comprehensive outpatient cardiovascular rehabilitation (CCR) program using concurrent exercise training prescribed according to cardiovascular risk stratification on cardiorespiratory fitness (CRF), anthropometric/body composition, quality of life and emotional health in patients of four cardiovascular disease profiles. Methods: CRF, anthropometric/body composition, quality of life, and emotional health were measured before and after a CCR and analyzed in heart valve surgery (HVS), heart failure with reduced ejection fraction (HFrEF), post-acute myocardial infarction (post-AMI), and in coronary artery disease (CAD) patients. Twenty, twenty-four, and thirty-two exercise sessions were prescribed according to mild, moderate, and severe baseline cardiovascular risk, respectively.

[Cardiac myxomas. Analysis of 78 cases].

Background: The incidence rates of cardiac tumors are low.

Aim: To report the clinical presentation of cardiac myxomas and long-term evolution after resection.

Material And Methods: Review of a database of surgical patients undergoing surgical resection of a cardiac myxoma in a public hospital between 1990 and 2018.

[Hospital mortality and long-term survival of 103 patients with infective endocarditis requiring surgery].

Background Infective endocarditis (IE) is a serious disease with high mortality, especially among the most severe cases undergoing surgery. Aim To analyze the clinical features, perioperative mortality and long-term survival of patients with infective endocarditis requiring surgery. Material and Methods Review of medical records of patients who underwent heart valve surgery for active infective endocarditis in a public hospital between 1995 and 2008.

Left ventricular assist device (LVAD) program in Chile: first successful experience in South America.

Background: The need to have a variety of tools to deal with end-stage heart failure (ES-HF), along with the limited heart transplantation availability encouraged us to create a pilot Left ventricular assist device (LVAD) program in a public health care system hospital in Chile.

Methods: A retrospective analysis of the first nine patients of an ongoing LVAD program initiated on August 2013 was performed, completing an average of 30 months of follow-up. The most important events regarding to morbidity and mortality are described.

[Left ventricular assistant devices for end-stage heart failure: report of two cases].

In the last 2 decades, there have been significant advances in medical treatment of heart failure. However, there is a group of patients who are refractory to the available medical therapy and progress inevitably to a state of end-stage heart failure, whose only therapeutic alternative is cardiac transplantation. But this is an option limited by the scarce availability of donors.

Complementary roles of transthoracic two-dimensional color Doppler imaging and myocardial contrast echocardiography in diagnosis of endomyocardial fibrosis.

Endomyocardial fibrosis (EMF) is a rare progressive restrictive cardiomyopathy of unknown etiology that mainly presents with heart failure. The presence of a small ventricle with obliteration of the apex and a large atrium are two-dimensional echocardiographic findings that are highly suggestive of EMF. Cardiac magnetic resonance with delayed enhancement allows detection of subendocardial fibrosis with good histopathological correlation, providing a noninvasive modality for diagnosing EMF.

Risk scores do not predict high mortality after coronary artery bypass surgery in the presence of diastolic dysfunction.

Background: Although global postoperative mortality after on-pump coronary artery bypass grafting is approximately 3%, in some groups it can be considerably higher. Many conditions are known to increase mortality and have been included in well-known scoring systems; however, left ventricular diastolic dysfunction has not been sufficiently evaluated to identify its predictive value for mortality after coronary artery bypass grafting, nor is it integrated in currently used risk scores.

Methods: Left ventricular filling pattern was prospectively evaluated in 191 patients scheduled for on-pump coronary artery bypass grafting.

[Severe aneurismal coronary artery disease probably caused by Kawasaki disease. report of one case].

We report a 16 year old male with a history of angina on exertion. A treadmill exercise test was positive for ischemia in concordance with a Thallium-201 scintigraphy showing a septal and infero-posterior reversible myocardial perfusión defect. Coronary angiography disclosed severe aneurysmal coronary artery disease.
