Stress echocardiography (SE) is a well-established and valid technique, widely-used for the diagnostic evaluation of patients with ischemic and non-ischemic cardiac diseases. This statement of the Echocardiography Working Group of the Hellenic Society of Cardiology summarizes the consensus of the writing group regarding the applications of SE, based on the expertise of their members and on a critical review of current medical literature. The main objectives of the consensus document include a comprehensive review of SE methodology and training, focusing on the preparation, the protocols used and the analysis of the SE images and an updated, evidence-based knowledge about SE applications on ischemic and non-ischemic heart diseases, such as in cardiomyopathies, heart failure and valvular heart disease.

Purpose. In the present study we sought to assess the gender-specific prevalence, treatment rates, and control of hypertension, as well as to identify its associated conditions and additional cardiovascular (CV) risk factors, in a Greek population aged ≥ 65 years old. Methods. This is a population-based study including a clinical interview, an ECG recording, and blood pressure (BP) measurements by sphygmomanometer. Results. The overall prevalence of hypertension was 83.3%, higher in females and increasing with age. In males, hypertension was independently associated with increased body mass index (BMI), a history of stroke, and myocardial infarction, while in females increased age, BMI, and a history of diabetes were independently associated with hypertension. A considerable proportion of hypertensives were treated (77.3%), while an effective control of BP was achieved in 42.5% of treated subjects. Despite the fact that hypertension treatment rates did not differ between the genders, control rates were lower among females. Finally, more hypertensive females presented additional CV risk factors than normotensives. Conclusion. Elderly females exhibit a higher prevalence of hypertension and are characterized by lower hypertension control compared to hypertensive males.

Paravalvular leak (PVL) remains a clinically important complication after surgical or transcatheter valve implantation, presenting predominantly with heart failure (HF) and/or high-shear hemolysis. While redo surgery can be definitive, contemporary candidates frequently carry prohibitive operative risk, positioning transcatheter PVL closure as a key therapeutic alternative. However, available outcome data are largely derived from observational series and registries with heterogeneity in PVL mechanisms, prosthesis types, imaging protocols, and endpoint definitions. Standardized frameworks—such as those proposed by the PVL Academic Research Consortium—support harmonized PVL grading and clinically meaningful composite endpoints that integrate imaging/hemodynamic results with patient-centered outcomes. Across datasets, the most consistent determinant of benefit is residual PVL severity: procedural efficacy is most commonly defined as achieving ≤ mild residual regurgitation without prosthetic leaflet interference, device embolization, or major complications. This review provides a step-by-step, phenotype-driven approach to transcatheter PVL closure, emphasizing multimodality imaging (TEE and cardiac CT, with adjunct CMR and PET when appropriate), access and support planning tailored to valve position, and morphology-matched device selection—often requiring modular multi-device strategies for elongated crescentic channels, particularly in hemolysis-predominant presentations. We also synthesize evidence on complications and bailout management, with a focus on preventable high-severity events (leaflet impingement, embolization, stroke/air, vascular injury, tamponade) and standardized pre-release safety checks. Collectively, contemporary practice supports high implant success in experienced programs, with clinical improvement tightly coupled to procedural endpoint quality and careful Heart Team selection.

Background/Objectives: Valve-in-valve (ViV) transcatheter aortic valve implantation (TAVI) is a key approach for treating degenerated surgical bioprosthetic valves. The ACURATE neo2 valve, with its advanced sealing technology and optimized coronary access, represents a promising solution for the challenges of ViV TAVI. This study evaluates the procedural and 30-day and 1-year follow-up outcomes of the ACURATE neo2 valve in ViV TAVI. Methods: This single-center, single-operator prospective study included patients with symptomatic bioprosthetic valve dysfunction, classified in New York Heart Association (NYHA) class III or IV, who underwent ViV TAVI with ACURATE neo2 at our center between July 2022 and February 2024. Outcomes were assessed using VARC-3 criteria. Results: Fifty-five patients (51% females, median (IQR) age 76 (8) years) were included. The technical success rate was 98.2%. No patients experienced in-hospital mortality, stroke, MI, bleeding, vascular complications, renal failure, or new pacemaker implantation. Three patients (5.5%) underwent elective chimney stenting for coronary protection. The postprocedural mean aortic gradient was 6.7 ± 1 mmHg, with a mean aortic valve area (AVA) of 2.0 ± 0.1 cm². Over a median follow-up period of 1.2 years, no deaths (0%) were observed, heart failure hospitalization rate was 3.6%, and NYHA class improved to ≤II in 100% of patients. Conclusions: ACURATE neo2 demonstrated excellent technical success, sustained hemodynamic performance, and significant clinical improvement in ViV TAVI. The absence of major adverse events reinforces its safety, efficacy, and durability as a treatment for degenerated surgical bioprostheses.
