ABSTRACT
In 2019 the European Society for Cardiology (ESC) published guidelines for the diagnosis and management of chronic coronary syndromes (CCS). Thus the term "stable coronary artery disease" is replaced by CCS. The newly introduced term is based on the current understanding of pathogenesis and clinical features of coronary artery disease (CAD) as well as therapeutic management. CCS defines CAD as a chronic process that can be influenced by lifestyle adjustments, pharmacological therapies and invasive interventions (percutaneous coronary intervention, coronary artery bypass grafting) with the aim of stabilization or regression. The present work provides an overview of various scenarios that involve CCS and diagnostic pathways to clarify potentially relevant CAD. It also highlights therapeutic management and secondary preventive procedures in accordance with the current recommendations of the ESC.

AIMS: Percutaneous mitral annuloplasty (PMA) represents a new treatment option for secondary mitral regurgitation (SMR) being associated with higher morbidity and mortality. The present study was aimed to evaluate whether or not acute effects on SMR severity can quantitatively be assessed after PMA. METHODS AND RESULTS: PMA was performed in 30 patients (mean age 76 ± 9; 37% males) with moderate (n = 14) or severe (n = 16) SMR. Vena contracta (VC), left ventricular (LV) velocity-time-integral ratio (VTIMV/LVOT ), effective regurgitant orifice area (EROA) by two-dimensional proximal isovelocity surface area (PISA), regurgitant volume (RVolPISA ) and regurgitant fraction (RFPISA ) by PISA, RVolvolume and RFvolume by LV volume analyses, and parameters describing LV morphology, function, and cardiac performance were assessed by transthoracic echocardiography prior to and after PMA. According to RFPISA /RFvolume , 14 patients showed mild, 15 moderate, and 1 severe SMR after PMA. Mean RF, RVol, EROA, VC, and VTIMV/LVOT were lower directly after PMA (RFPISA : 49% ± 11 vs. 34% ± 13, P < 0.001; RFvolume : 46% ± 10 vs. 34% ± 13, P < 0.001; RVolPISA : 33 mL ± 13 vs. 25 mL ± 12, P < 0.001; RVolvolume : 28 mL ± 17 vs. 20 mL ± 14, P < 0.05; EROAPISA : 0.24 cm2 ± 0.1 vs. 0.19 cm2 ± 0.1, P < 0.05; VC: 5.2 ± 0.1 vs. 4.1 ± 0.2, P < 0.001; VTIMV/LVOT : 1.9 ± 0.4 vs. 1.6 ± 0.5, P < 0.05). Parameters of LV morphology, function, and cardiac performance did not change directly after PMA. CONCLUSIONS: PMA leads to a reduction of MR severity in >80% of SMR patients. Acute effects of PMA can quantitatively be assessed by transthoracic echocardiography.

Purpose The study compares the feasibility of the quantitative volumetric and semi-quantitative approach for quantification of chronic aortic regurgitation (AR) using different imaging modalities. Methods Left ventricular (LV) volumes, regurgitant volumes (RVol) and regurgitant fractions (RF) were assessed retrospectively by 2D, 3D echocardiography and cMRI in 55 chronic AR patients. Semi-quantitative parameters were assessed by 2D echocardiography. Results 22 (40%) patients had mild, 25 (46%) moderate and 8 (14%) severe AR. The quantitative volumetric approach was feasible using 2D, 3D echocardiography and cMRI, whereas the feasibility of semi-quantitative parameters varied considerably. LV volume (LVEDV, LVESV, SVtot) analyses showed good correlations between the different imaging modalities, although significantly increased LV volumes were assessed by cMRI. RVol was significantly different between 2D/3D echocardiography and 2D echocardiography/cMRI but was not significantly different between 3D echocardiography/cMRI. RF was not statistically different between 2D echocardiography/cMRI and 3D echocardiography/cMRI showing poor correlations (r < 0.5) between the different imaging modalities. For AR grading by RF, moderate agreement was observed between 2D/3D echocardiography and 2D echocardiography/cMRI and good agreement was observed between 3D echocardiography/cMRI. Conclusion Semi-quantitative parameters are difficult to determine by 2D echocardiography in clinical routine. The quantitative volumetric RF assessment seems to be feasible and can be discussed as an alternative approach in chronic AR. However, RVol and RF did not correlate well between the different imaging modalities. The best agreement for grading of AR severity by RF was observed between 3D echocardiography and cMRI. LV volumes can be verified by different approaches and different imaging modalities.
ABSTRACT
Published registries give limited information on age-dependent complication rates. There are several reasons for this, including limited numbers of patients in subgroups (e.g., contractility management), experience-dependent procedures (e.g., catheter ablation), or in changing indications (e.g., resynchronization). Finally, severely ill and very old patients with limited prognosis are often excluded from electrophysiologic procedures. Therefore, published data are difficult to interpret. Meta-analyses of randomized trials give more precise information on included patient cohorts, but do not necessarily reflect daily practice because elderly patients are often excluded from trials. Therefore, the individual risk of elderly patients has to be estimated on an individual case basis. In summary, the age of patients is not relevant regarding possible complications; thus, there is no age limit for electrophysiologic interventions. Therefore, there is no alternative to the individual estimation of procedural risks of interventions of an informed patient by an experienced cardiologist.

The treatment of atrial fibrillation has to take into account the underlying cardiac and extracardiac diseases. A successful treatment of the underlying disease will only be sufficient treatment of atrial fibrillation in very rare situations. Therefore, this review focuses on the consequences of underlying heart disease, the hemodynamics and concomitant clinical situations on the treatment of atrial fibrillation.
