Sodium-glucose cotransporter-2 (SGLT2) inhibitors are currently the second-line pharmacotherapy in type 2 diabetes, particularly through their effectiveness in reducing glycemia, but also due to their cardioprotective and nephroprotective effects. In light of surprisingly satisfactory results from large, randomized trials on gliflozins, SGLT2 received the highest recommendation (Class IA) with the highest level of evidence (A) in the treatment algorithm for HF with reduced LVEF in recent ESC HF guidelines. This great breakthrough in the treatment of HF is due to different mechanisms of action of gliflozins that are reported to be able to change the natural course of HF by reducing the risk of both hospitalization and death. They are recommended regardless of the patient’s diabetes status. This review summarizes the up-to-date literature on their beneficial and pleiotropic impact on the cardiovascular system.

Background:The implantable cardioverter-defibrillator (ICD) and subcutaneous ICD (S-ICD) are well-accepted life-saving devices for treating potentially lethal ventricular arrhythmia, but little is known about quality of life (QoL) in patients with S-ICD and ICD.Aims: Our study aimed to compare QoL in patients with S-ICD and ICD. Methods: All consecutive patients who had S-ICD implanted between October 2015 and September 2021 were included in the study. A cohort of transvenous ICD (TV-ICD) patients was matched to S-ICD subjects by sex, age, indications for the device, and type of prevention. All patients were requested to fulfill two standardized questionnaires to assess QoL: 36-Item Short Form Health Survey (SF-36) and Minnesota Living with Heart Failure Questionnaire (MLHFQ) 6 months after device implantation.Results: Patients with S-ICD (n = 49) and TV-ICD (n = 49) did not differ regarding baseline characteristics. There were no statistically significant differences between S-ICD and TV-ICD subgroup, both for mental and physical QoL assessed in SF-36 and MLHFQ (all P = NS). The median MLHFQ total score was 24 (9-41) for S-ICD and 28 (14-43) for TV-ICD (P = 0.83). The median total score for the SF-36 questionnaire was 62.5 (29-86) vs. 59 (38-77) for S-ICD and TV-ICD, respectively (P = 0.78).Conclusions: Quality of life after device implantation does not differ significantly between the groups of patients with subcutaneous and conventional implantable cardioverter-defibrillator.

The development of the SARS‐CoV‐2 pandemic caused a common appearance of severe pulmonary complications, rarely seen as a result of the other infections. These are pneumothorax, pneumomediastinum, emphysematous bullae, cavitary lung lesions, or subcutaneous emphysema. Their formation is influenced by both—the natural course of the disease and the treatment strategy adopted.

We report a 15‐year‐old male with hypoplastic left heart syndrome (HLHS) after Fontan operation with recurrent, drug‐resistant atrial tachycardia. With the use of electro‐anatomical mapping system (EnSite) an atrial flutter (AFl) with reentry activation around the tricuspid valve was diagnosed. Successful radiofrequency catheter ablation (RFCA) was performed.
