Background: The use of rapid deployment and sutureless aortic prostheses is increasing. Previous reports have shown promising results on haemodynamic performance and mortality rates. However, the impact of these bioprostheses on left ventricular mass (LVM) regression remains unknown. We decided to study the changes in remodelling and LVM regression in isolated severe aortic stenosis treated with conventional or Perceval® or Intuity® valves.
Method And Results: From January 2011 to January 2016, 324 bioprostheses were implanted in our centre. The collected characteristics were divided into 3 groups: conventional valves, Perceval®, and Intuity®, and they were analysed after 12 months. There were 183 conventional valves (56%), 72 Perceval® (22%), and 69 Intuity® (21.2%). The statistical analysis showed significant differences in transprosthetic postoperative peak gradient (23 [18-29] mm Hg vs. 21 [16-29] mm Hg and 18 [14-24] mm Hg, p < 0.001), ventricular mass electrical criteria regression (Sokolow and Cornell products), and 1-year survival (90 vs. 93% and 97%, log rank p value = 0.04) in conventional, Perceval®, and Intuity® groups.
Conclusions: We observed differences in haemodynamic, electrocardiographic, and echocardiographic parameters related to the different types of prosthesis. Patients with the Intuity® prosthesis had the highest reduction in peak aortic gradient and the higher ventricular mass regression. Besides, patients with the Intuity® prosthesis had less risk of mortality during follow-up than the other two groups. Further studies are needed to confirm these findings.

A left ventricular sub-mitral thrombus without an aneurysm is a previously unreported rare occurrence. We aim to bring attention to this finding in a case of colorectal adenocarcinoma.An early 60s-year-old female presented with bleeding per rectum, weight loss and fatigue and was found to have colorectal carcinoma with metastasis based on examination, imaging and biopsy findings.

Background: Electronic nicotine delivery systems (ENDS) utilize "E-liquids" in order to generate "E-vapor", an inhalable aerosolized mixture containing nicotine and flavors. Flavored ENDS are very popular among teens who vape, however, the possible cardiac electrophysiological harm of inhalation exposure to flavored ENDS are not fully understood.
Objective: To test if inhalation exposure to flavoring carbonyls in e-liquids compromises mitochondrial integrity, increases oxidative stress, and leads to cardiac electrophysiological toxicity.

Background: Athlete's heart, characterized by cardiac chambers adaptations to exercise has some diagnostic overlaps with dilated cardiomyopathy (DCM). In the setting of differential diagnosis, myocardial work indexes (MWI), afterload-independent tool, could be helpful to identify early subclinical alterations. The aim of our study was to assess the utility of MWI in athletes with mildly reduced left ventricular ejection fraction (LVEF).

Baroreflex activation therapy (BAT) improves functional status, quality of life, and exercise capacity in patients with heart failure with reduced ejection fraction; however, its direct effects on reversing adverse cardiac remodeling as assessed by improvements in cardiac structure, function, and coupling with the arterial system remain unclear. We present 2 cases of patients who initially presented with decompensated heart failure, and despite initial medical therapy and continued outpatient follow-up, were unable to tolerate full escalation of guideline-directed medical therapy. The patients remained symptomatic, with high biomarker levels, poor functional capacity, severe heart failure symptoms, and objectively had decreased stroke volume, low left ventricular ejection fraction, and high left ventricular mass.

At the first stage, 878 patients with shortness of breath were screened three or more months after COVID-19, and the presence of at least three diagnostic criteria for CHF, that were not in their history, was verified.
