INTRODUCTION: Transcatheter aortic valve implantation (TAVI) is an emerging minimally invasive treatment modality in high surgical risk or inoperable patients. AIM: The aim of this study was to ascertain the effect of TAVI on left ventricular (LV) systolic and diastolic function and serum B-type natriuretic peptide (BNP) levels in high surgical risk or inoperable patients with severe aortic stenosis. METHODS: Fifty-five patients were included in our retrospective study...

We present a case of an accidentally crushed stent due to an unnoticed passage of a guidewire through a lateral stent strut with subsequent stent compression after balloon dilatation, during a planned percutaneous coronary intervention on the left main. The crushed stent segment was reconstructed with step-by-step balloon dilation, guided by intravascular ultrasound.

INTRODUCTION AND OBJECTIVES: Cardiovascular disease is the leading cause of mortality and morbidity associated with diabetes. Although impairment of the cell response to hypoxia due to destabilization of the transcription factor hypoxia-inducible factor-1α (HIF-1α), which regulates the expression of genes that help cells to cope with low oxygen tension, has been implicated in diabetes-associated disease, the molecular mechanisms involved remain elusive. It is known that hyperglycemia leads to the enhanced production of methylglyoxal (MGO)...

INTRODUCTION: Familial amyloid polyneuropathy (FAP) is a rare disease caused by systemic deposition of amyloidogenic variants of the transthyretin (TTR) protein. The TTR-V30M mutation is caused by the substitution of valine by methionine at position 30 and mainly affects the peripheral and autonomic nervous systems. Cardiovascular manifestations are common and are due to autonomic denervation and to amyloid deposition in the heart. Cardiac sympathetic denervation detected by iodine-123 labeled metaiodobenzylguanidine (MIBG) is an important prognostic marker in TTR-V30M FAP...

The International Committee of Medical Journal Editors (ICMJE) provides recommendations to improve the editorial standards and scientific quality of biomedical journals. These recommendations range from uniform technical requirements to more complex and elusive editorial issues including ethical aspects of the scientific process. Recently, registration of clinical trials, conflicts of interest disclosure, and new criteria for authorship -emphasizing the importance of responsibility and accountability-, have been proposed...

INTRODUCTION: Sympathetic renal denervation (RDN) was developed as a treatment for the management of patients with resistant hypertension. This procedure may have a positive impact on hypertension-related target organ damage, particularly renal disease, but the evidence is still limited. OBJECTIVE: To assess the impact of RDN on the albumin-to-creatinine ratio (ACR) at 12-month follow-up. METHODS AND RESULTS: From a single-center prospective registry including 65 patients with resistant hypertension undergoing renal denervation, 31 patients with complete baseline and 12-month follow-up blood pressure (BP) measurements (both office and 24-h ambulatory blood pressure monitoring [ABPM]) and ACR were included in the present study...

INTRODUCTION AND OBJECTIVE: Obesity is a major risk factor for cardiovascular disease. This study was designed to assess whether the conicity index (CI), body mass index (BMI) and waist circumference (WC) can be used as predictors of coronary artery disease (CAD) and mortality in a middle-aged population of the north-western region of Rio Grande do Sul, Brazil. METHODS: This was a retrospective, longitudinal cohort study, based on the medical records of patients seen in a cardiology institution in a rural area of Rio Grande do Sul...

Kounis syndrome (KS) is the coincidental occurrence of acute coronary syndrome (ACS) and anaphylactic or allergic insult. It results from mast cell degranulation with subsequent release of numerous inflammatory mediators, leading to coronary vasospasm or atheromatous plaque rupture. Diagnosis is clinical and based on the temporal relationship between the two events. Despite the growing number of reported cases, especially in southern Europe, the lack of awareness of this association may lead to under-reporting in Portugal...

Beta blockers are commonly used to treat hypertension. This Cochrane systematic review assessed the effect of beta-1 selective beta blockers on blood pressure (BP), pulse pressure (PP), heart rate (HR) and withdrawal due to adverse effects in patients with primary hypertension. Fifty-six randomized placebo-controlled trials were included, with a total of 7812 patients. These drugs reduced systolic/diastolic BP by 10/8 mmHg, PP by 2 mmHg and HR by 11 bpm; no difference was found between treatment and placebo regarding withdrawal due to adverse effects...

INTRODUCTION: Rotors and complex fractionated atrial electrograms (CFAEs) have been suggested as possible therapeutic targets in ablation of atrial fibrillation (AF). The aim of this study was to assess the relationship between rotors and CFAEs in patients with AF. METHODS: We studied 18 patients with AF (mean age 69±8 years, 33% female) who underwent rotor ablation and pulmonary vein isolation. Endocardial mapping was performed with a basket catheter to identify the presence, number and location of rotors and CFAEs...
