Journal of Transcatheter Interventions

Letter to: Latin American Association of Cardiac and Endovascular Surgery. Dayan et al.1 , on behalf of the Latin American Association of Cardiac and Endovascular Surgery (LACES), expressed their concerns about the development and relevance of our clinical practice guideline for the use of transcatheter aortic valve implant (TAVI) or surgical aortic valve replacement (SAVR), in patients with severe aortic stenosis living in Latin America.2 In this response, we address several points raised in their letter.1 […]

A 67-year-old man with several cardiovascular risk factors was referred to cardiology consultation, due to effort angina – Canadian Cardiology Society (CCS) class II/IV, for the last 6 months, under optimal medical treatment. Resting electrocardiogram and transthoracic echocardiogram (TTE) were normal. Stress treadmill test was positive. The coronary angiogram revealed a long proximal chronic total occlusion (CTO) of the left anterior descending artery (LAD; J-CTO=1, Rentrop3), a distal CTO of the left circumflex artery (J-CTO=0, Rentrop3) and a 50% stenosis […]

ABSTRACT Invasive physiological assessment of the coronary circulation has emerged in recent years as a valuable diagnostic approach in the management of patients with chronic coronary syndrome, overcoming important limitations such as evaluating function from the anatomy and the low spatial resolution associated with angiography or non-invasive tests. The value of hyperemic flow measurements to estimate the functional relevance of coronary stenoses is supported by many studies. The aim of this paper is to review the physiological bases, clinical applications […]

ABSTRACT The Gerbode defect is defined as an abnormal communication between the left ventricle and the right atrium, and is etiologically classified as congenital or acquired (iatrogenic or not). The typical treatment consists of surgical repair of the shunt, but transcatheter occlusion of this condition has proven to be a safe and effective therapeutic alternative for such patients, especially for those with prior surgeries. The aim of this study was to report a case of transcatheter closure of an acquired […]

ABSTRACT Since the mid-1990s, the dual antiplatelet therapy, consisting of the association between acetylsalicylic acid and a platelet P2Y12 receptor inhibitor, is the core of thrombosis prevention after coronary stent implantation, regardless of the models used. It is also used to prevent the occurrence of atherothrombotic events in the late phase after the intervention. The clinical presentation of coronary artery disease influences the duration of dual therapy, which tends to be longer in treated cases of acute coronary syndrome (usually […]

The Journal of Transcatheter Interventions has gained notable academic strengthening with quality publications in the field of percutaneous intervention in heart (coronary and non-coronary), peripheral and cerebrovascular diseases. This growth has occurred due to work of our reviewers. In 2021, this task was conducted with excellence by the following professionals: Alexandre do Canto Zago […]

ABSTRACT Ventricular diverticulum is a rare congenital malformation. Although most patients are asymptomatic, it can present with rupture and sudden death, for which surgical repair is indicated. The authors report the case of a 5-year-old boy with a prenatal diagnosis of an isolated left ventricular diverticulum. It was decided for surgical closure; however, a persisting leakage at the patch repair site was observed, for which a transcatheter percutaneous closure approach was used, achieving complete occlusion of the defect. Transcatheter closure […]

ABSTRACT Background: Coronary artery disease is a major public health concern worldwide. In Africa, varying rates of progression increased in different countries. In Angola, although the epidemiological scenario is dominated by infectious diseases, the prevalence of coronary artery disease is increasing with notable impacts, requiring the creation of mechanisms to face this reality in a country where lack of specific infrastructure is still a challenge. The objective of this study was to describe the experience of primary angioplasty in patients […]

ABSTRACT Left ventricular free wall rupture is one of the most catastrophic and lethal mechanical complications associated with myocardial infarction. Its diagnosis in a patient still alive is rare, and its only therapeutic option is open surgical treatment. We report the case of an 82-year-old male patient who presented with an acute ST-segment elevation myocardial infarction, within more than 24 hours of onset, in which it was possible to record, in real time, the rupture of the left ventricular free […]

ABSTRACT Transcatheter aortic valve implantation is considered a standard treatment for many symptomatic patients with severe aortic stenosis. Coronary artery occlusion after transcatheter aortic valve implantation is associated with a mortality rate of up to 50%. In this case report we described a patient with severe aortic bioprosthesis dysfunction, at high risk of coronary obstruction after transcatheter aortic valve implantation. This patient underwent Basilica procedure followed by valve-in-valve transcatheter aortic valve implantation. The patient demonstrated good improvement and was discharged […]
