Distinguished and competent professionals, fundamental to the consolidation and advancement of the specialty in our country have left us, after serving brilliantly their career in this world. On July 10, 2014, Dr. Geraldo Verginelli died. On November 12, 2014, Dr. Raul Correia Rabelo left our living and just two days later, we had the death of Dr. Adib Domingos Jatene. In 2015, we had three more losses: on February 21, Dr. Edgar San Juan died (see Memorial, written by Dr. Vera Piccardi on page 395), on May 26, Dr. Marcos Vinicius Ferraz Arruda has lost the battle to cancer, the same occurred on the 5th of July with Dr. João Alberto Roso. But we can not just lament these happenings. We must look into the achievements of these cardiac surgeons, draw lessons from their teachings and apply them in our day-to-day, not only in the professional field, but also in personal life. Thanks to the dedication of the pioneers in times when our specialty still crawled, without stopping, let alone giving up in the face of obstacles, making their work and creativity and managing to overcome difficulties, it was possible to put the Brazilian cardiac surgery in the prominent place it occupies today in the world. Their example will be forever and the best way to honor them is with great dedication, whether at work, whether in research, so that the problems we face today with the crisis befalling the country and affects everyone, decreasing financial resources, do not take the courage nor the will to fulfill our role as best as possible. And these teachers gave us real lessons of the heart that we must always have them saved, especially in times where the situation appears adverse. Dr. Adib said: “I am against this story to tell: I don’t do because they don’t give me conditions. If you are able to do you create the conditions.” We can learn from these true heart lessons! Brazilian Journal of Cardiovascular Surgery (BJCVS) emerged from this dream, and if today is an internationally recognized journal, it owes much to the pioneers.

Director of Pacemaker Service of Instituto Dante Pazzanese de Cardiologia (IDPC), Sao Paulo, SP, Brazil. E-mail: pachon@usp.br Chagas disease or American trypanosomiasis is a chronic parasitosis affecting most Latin American countries where an estimated 8 million people are infected. Current assessments have shown that even in the United States there is a total of 300,000 infected individuals, essentially all of whom are immigrants from the endemic countries. It is a tropical parasitic disease caused by the protozoan Trypanosoma cruzi that is transmitted to humans by blood-sucking triatomine bugs, known as “Kissing Bug”, and via blood transfusion, mother-to-baby or organ transplant. This protozoan causes an acute systemic inflammatory illness that usually progresses to chronic myocarditis and autonomic disease leading to electrical and/or severe dilated cardiomyopathy. Myocardial damage is disseminated throughout the heart. The outcome may present cardiac arrhythmias, life-threatening heart failure, thromboembolism, stroke and sudden death. The latter is sometimes the first manifestation of the disease, even in the structurally normal heart (latent phase). In many patients, a chronic immunologic process may feed the inflammatory phenomenon even without the parasite. As a rule, extensive involvement of the autonomic nervous system and the cardiac conduction system results in a huge variety of supraventricular and ventricular cardiac arrhythmias. As a corollary, in approximately 60% of cases, the sinus node is injured, developing a more or less extensive sick sinus syndrome. Additionally, many patients have to be treated for heart failure and cardiac arrhythmias. Thanks to a coordinated multi-country program in the Southern Cone countries, the transmission of Chagas disease by vectors and via blood transfusion was interrupted in Uruguay in 1997, in Chile in 1999 and Brazil in 2006. For this reason, the incidence of new infections by T. cruzi across the South American continent has decreased by 70%. The natural course of the disease and the very common pharmacological requirement for treating numerous arrhythmias cause a high sick sinus node syndrome prevalence. One frequent expression of this condition is the “Chronotropic Incompetence” (CI).","PeriodicalId":87739,"journal":{"name":"Revista brasileira de cirurgia cardiovascular : orgao oficial da Sociedade Brasileira de Cirurgia Cardiovascular","volume":"30 3","pages":"III-VI"},"PeriodicalIF":0.0,"publicationDate":"2015-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4541789/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34126083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
