Abstract
In the transcatheter aortic valve implantation (TAVI) era, the indications for balloon aortic valvuloplasty (BAV) are increasing. Previously, the INOUE-BALLOON® (IB) was used only for antegrade BAV, but recently, it has also been used for retrograde BAV. However, the safety and feasibility of retrograde BAV using an IB are not fully understood. In this study, we investigated the safety and feasibility of retrograde BAV using an IB in elderly Japanese patients with severe aortic stenosis (AS). We compared 39 cases of retrograde BAV using an IB performed from June 2018 to September 2020 and 34 cases of antegrade BAV using an IB performed from August 2013 to May 2018. The total number of complications was lower in retrograde BAV than in antegrade BAV (p = 0.020). The procedure time was significantly shorter in retrograde BAV than in antegrade BAV (p < 0.001), and the maximum balloon size and number of balloon inflations were smaller in retrograde BAV than in antegrade BAV (p = 0.002 and p < 0.001, respectively). There was no significant difference in the degree of improvement in the aortic valve area or ejection fraction between retrograde and antegrade BAV. In conclusion, the present study showed the safety and feasibility of retrograde BAV using an IB in elderly Japanese patients with severe AS compared with antegrade BAV using an IB.

Abstract
BACKGROUND In our institute, the causes of mitral stenosis (MS) are generally categorized into three main etiologies-rheumatic MS (RMS), degenerative MS with annular and leaflet calcification, and post-clip MS as a consequence of transcatheter mitral valve repair with clips for treating mitral regurgitation. However, clinical differences among the three etiologies are uncertain. METHODS We retrospectively assessed 293 consecutive patients (53 with RMS, 118 with degenerative MS, and 122 with post-clip MS) who had a three-dimensional (3D) transesophageal echocardiography (TEE) derived mitral valve orifice area (MVA) of ≤1.5 cm2 , and a mean transmitral pressure gradient of ≥5 mmHg on transthoracic echocardiography. RESULTS Although there was no difference in 3D-TEE-derived MVA among the three groups, patients with post-clip MS had a significantly lower mean transmitral pressure gradient compared to those with either of the other two types of MS (10.8 ([7.9-15.2] mmHg vs. 9.6 [7.3-12.5] mmHg vs. 6.9 [6.0-9.2] mmHg; p < .001). Patients with RMS had a higher prevalence of dyspnea. The independent determinants of dyspnea were pressure half time in RMS, 3D-TEE-derived MVA and estimated right atrial pressure in degenerative MS, and left ventricle ejection fraction in post-clip MS. CONCLUSIONS Patients with post-clip MS had the lowest mean transmitral pressure gradient, and patients with RMS had the highest prevalence of dyspnea, despite having a similar 3D-TEE-derived MVA. The determinants of dyspnea were different among the three etiologies of MS.

Abstract
Background Little is known about the impact of diastolic interventricular septal flattening on the clinical outcome in patients with severe tricuspid regurgitation. This study sought to evaluate the association of diastolic interventricular septal flattening with clinical outcome in patients with severe tricuspid regurgitation. Methods and Results We retrospectively studied 407 patients who underwent 2‐dimensional transthoracic echocardiography and were diagnosed with severe tricuspid regurgitation between January 2014 and December 2015. Cardiovascular events were defined as cardiovascular death or admission for heart failure. The magnitude of interventricular septal flattening was calculated by the eccentricity index (EI) of the left ventricle, and hemodynamic parameters were obtained from transthoracic echocardiography. During follow‐up (median, 200 days; interquartile range, 35–1059), 117 of the patients experienced cardiovascular events. By multivariate analysis including potential covariates, EI at end‐diastole and left ventricular ejection fraction were independent predictors of cardiovascular events (hazard ratio, 5.33 [1.63–17.41]; hazard ratio, 0.98 [0.97–0.99], respectively). An EI of 1.2 at end‐diastole was the optimal cutoff value for identifying poor hemodynamic status defined as cardiac index ≤2.2 L/min per m2 and right atrial pressure 15 mm Hg, both on transthoracic echocardiography. Patients with D‐shaped left ventricle defined as EI ≥1.2 at end‐diastole showed worse outcomes than those without (adjusted hazard ratio, 1.80 [1.18–2.74]). Conclusions Increasing EI at end‐diastole was strongly associated with worse outcomes in patients with severe tricuspid regurgitation. Furthermore, the presence of D‐shaped left ventricle defined as EI ≥1.2 at end‐diastole provides prognostic value for cardiovascular events.

Abstract
AIMS This study investigated geometric differences in mitral valve apparatus between atrial functional mitral regurgitation (A-FMR) and functional mitral regurgitation (FMR) with left ventricular (LV) dysfunction in patients with atrial fibrillation (AF) using 3D transoesophageal echocardiography (TOE). METHODS AND RESULTS In total, 135 moderate or greater FMR patients with persistent AF or atrial flutter underwent 3D TOE. Fifty-six patients had A-FMR, defined as preserved LV ejection fraction (LVEF) of ≥50% and normal LV wall motion. Seventy-nine patients had ventricular FMR (V-FMR), defined as LV dysfunction (LVEF of <50%) or LV wall motion abnormality. To evaluate mitral leaflet coaptation, the coapted area was calculated as follows: total leaflet area (TLA) in end-diastole - closed leaflet area in mid-systole. Although annular area (AA) did not significantly differ between the two groups, TLA was significantly smaller in A-FMR than in V-FMR (P = 0.005). TLA/AA, indicating the degree of the leaflet remodelling, was significantly smaller in A-FMR than in V-FMR (P < 0.001). A-FMR had significantly smaller posterior mitral leaflet tethering height and angle measured at three anteroposterior planes (lateral, central, and medial) than V-FMR (all P < 0.001). However, vena contracta width (VCW) measured on long-axis view on TOE and coapted area, which correlated with VCW (r = -0.464, P < 0.001), were similar between the two groups. CONCLUSION Mitral leaflet remodelling may be less in A-FMR compared with V-FMR. However, leaflet tethering was smaller in A-FMR than in V-FMR, and this may result in a similar degree of mitral leaflet coaptation and mitral regurgitation severity.

Abstract
In patients with moderate aortic stenosis (AS), heart failure (HF) symptoms are often unrelated to the AS severity, and the causes of HF symptoms are often unclear. Hypertension is known as one of the most common comorbidities in degenerative AS. Therefore, we assessed the impact of systolic blood pressure (BP) on HF symptoms in patients with moderate AS. We retrospectively analyzed 317 patients with moderate AS (mean transaortic pressure gradient 20 to 39 mm Hg) and preserved left ventricular ejection fraction (left ventricular ejection fraction ≥50%). We classified patients according to the presence or absence of HF symptoms. One hundred patients (32%) had HF symptoms. Symptomatic patients had higher systolic BP (141±21 versus 129±21 mm Hg; p<0.001) and mean transaortic pressure gradient, and lower aortic valve area than asymptomatic patients. In the multivariable analysis after adjustment for age, atrial fibrillation, Charlson comorbidity index, brain natriuretic peptide, and the use of diuretics, HF symptoms in patients with moderate AS were independently associated with systolic BP (odds ratio, 1.43 per 10 mm Hg increase in systolic BP; 95% confidence interval, 1.14-1.78; p=0.001) and left atrial volume index (odds ratio, 1.04 per 1 mL/m2 increase in left atrial volume index; 95% confidence interval, 1.00-1.08; p=0.026). Receiver operating characteristics curve analysis identified systolic BP 133 mm Hg as the cutoff value associated with HF symptoms. In conclusion, systolic BP as well as left atrial volume index were independent correlates of HF symptoms in patients with moderate AS.

Abstract
BACKGROUND Left ventricular (LV) outflow tract (LVOT) obstruction increases mortality in patients undergoing transcatheter mitral valve implantation (TMVI) in degenerated bioprostheses, annuloplasty rings, and native mitral valves. We aimed to evaluate the LVOT area after TMVI using 3-dimensional (3D) transesophageal echocardiography (TEE) and to investigate the preprocedural cardiac geometry that affects the LVOT area after TMVI. METHODS We retrospectively reviewed echocardiography data in 43 patients who had TMVI. A change in pressure gradient across LVOT from before to after TMVI (∆PG) and postprocedure 3D LVOT cross-sectional area at the level of the most distal portion of the mitral valve stent that was closest to the LV apex were assessed as evidence of LVOT narrowing. RESULTS Transcatheter mitral valve implantation with the use of balloon-expandable valve system was performed for 24 bioprostheses, 7 annuloplasty rings, and 12 native valves. Compared to patients without increase in LVOT gradient (∆PG <10 mm Hg; n = 33), patients with increase in LVOT gradient (∆PG ≥10 mm Hg; n = 10) had smaller LV end-systolic volume (LVESV), greater LV ejection fraction (LVEF), and smaller aorto-mitral (AM) angle. The LVOT area at the valve stent distal edge showed strong association with ∆PG (r = -.68, P < .0001). Only a small AM angle was associated with a small LVOT area at the valve stent distal edge on multivariable analysis, independent of LVESV and LVEF. CONCLUSION Small LV size, preserved LVEF, and small AM angle were associated with LVOT narrowing. 3D-derived AM angle might be independently associated with LVOT narrowing in patients undergoing transcatheter mitral valve-in-valve, valve-in-ring, and valve-in-native valve implantation, independent of LVESV and LVEF.

Abstract
BACKGROUND A new grading of tricuspid regurgitation (TR) beyond severe has been proposed. However, few studies assessing the validity of such a new grading scheme of TR have been conducted. Therefore, we evaluated associations of TR grades beyond severe with patient outcome and hemodynamics. METHODS We retrospectively studied patients who underwent 2-dimensional echocardiography and were diagnosed with severe TR between January 2014 and December 2015. According to the vena contracta width of TR (VC), the patients were classified into 2 groups: VC under 14 mm (VC<14 mm) and VC 14 mm or greater (VC≥14 mm). Hemodynamic parameters were estimated by echocardiography and were obtained by right heart catheterization. Cardiovascular events were defined as cardiovascular death or admission for heart failure. RESULTS A total of 679 patients (mean 72±17 years, 56% women) were included. During follow-up (median, 158 days; range, 29-891), 210 patients experienced cardiovascular events. By multivariate analysis, VC≥14 mm and left ventricular ejection fraction were independent predictors of cardiovascular events (hazard ratio, 1.57 [1.06-2.33]; hazard ratio, 0.99 [0.98-0.99], respectively). Patients with VC≥14 mm had significantly lower cardiac index (median, 1.8 versus 2.1 L/min per m2, P=0.001) and a higher prevalence of right atrial pressure 15 mm Hg (74% versus 60%, P<0.001) on echocardiography. Also, right heart catheterization confirmed higher right atrial pressure in patients with VC≥14 mm than those with VC<14 mm (16±8 versus 12±6 mm Hg, P=0.004). The new subset classification developed by cardiac index and right atrial pressure both on echocardiography predicted cardiovascular events (Log-rank P<0.001). CONCLUSIONS The relationship of VC≥14 mm to adverse outcome and poor hemodynamics showed the clinical relevance and need of a new grading system beyond severe. The new hemodynamic subset classification provides additional prognostic value for cardiovascular events in patients with severe TR.

Abstract
The high prevalence of pulmonary hypertension (PH) in elderly patients is well known. However, much remains unknown about those population. We sought to find the clinical characteristics of echocardiographic PH and the prognostic factors in patients ≥90 years of age. We retrospectively reviewed 310 patients ≥90 years of age (median age 92 years, 64% women) diagnosed as echocardiographic PH (peak systolic pulmonary arterial pressure ≥40 mm Hg) with normal left ventricular systolic function. We defined left heart disease (LHD) as significant left-sided valve diseases, left ventricular hypertrophy and left ventricular diastolic dysfunction by using echocardiography. The endpoint was all-cause death at 2,000 days after diagnosis. LHD was found in 92% of patients. During the median follow-up of 367 days (interquartile range, 39-1,028 days), 151 all-cause deaths (49%) occurred. Multivariable Cox regression analysis demonstrated that right ventricular fraction area change <35% (adjusted hazard ratio [HR]: 2.31; p <0.001), pericardial effusion (adjusted HR: 2.28; p <0.001), serum albumin <3.5 g/dL (adjusted HR: 1.76; p = 0.001), chronic obstructive pulmonary disease (adjusted HR: 1.93; p = 0.001) and New York Heart Association (NYHA) class ≥II (adjusted HR: 1.73; p = 0.004) were associated with mortality after adjusted for age. In conclusion, LHD was significantly associated with echocardiographic PH in most patients ≥90 years of age. Also, the co-morbid factors at diagnosis (right ventricular systolic dysfunction, pericardial effusion, hypoalbuminemia, chronic obstructive pulmonary disease, and NYHA class ≥II) were independently associated with mortality.

Abstract
High serum uric acid (UA) level has been assumed to be a risk factor for left ventricular (LV) dysfunction; however, the precise relationship between these conditions has not been fully examined because many confounding factors are associated with UA level. We herein examined the precise relationship by proposing structural equation models. The study population consisted of 1432 cases with ischemic heart disease who underwent cardiac catheterization. Multiple regression analyses and covariance structure analyses were performed to elucidate the cause-and-effect relationship between UA level and LV ejection fraction (LVEF). A path model exploring the factors contributing to LVEF showed that high UA was a significant cause of reduced LVEF (P = 0.004), independent of other significant factors. The degree of atherosclerosis, as estimated by the number of diseased coronary vessels, was significantly affected by high UA (P = 0.005); and the number of diseased coronary vessels subsequently led to reduced LVEF (P < 0.001). Another path model exploring the factors contributing to UA level showed that LVEF was a significant cause of high UA (P = 0.001), while other risk factors were also independent contributing factors. This study clearly demonstrated that there was a close link between high UA and LV dysfunction, which was represented by possible cause-and-effect relationship.

Abstract
BACKGROUND The infusion of adenosine triphosphate after radiofrequency (RF) pulmonary vein (PV) isolation (PVI), which may result in acute transient PV-atrium reconnection, can unmask dormant conduction. OBJECTIVE The purpose of this study was to compare the incidence and characteristics of dormant conduction after cryoballoon (CB) and RF ablation of atrial fibrillation (AF). METHODS Of 414 consecutive patients undergoing initial catheter ablation of paroxysmal AF, 246 (59%) propensity score-matched patients (123 CB-PVI and 123 RF-PVI) were included. RESULTS Dormant conduction was less frequently observed in patients who underwent CB-PVI than in those who underwent RF-PVI (4.5% vs 12.8% of all PVs; P < .0001). The incidence of dormant conduction in each PV was lower in patients who underwent CB-PVI than in those who underwent RF-PVI in the left superior PV (P < .0001) and right superior PV (P = .001). The site of dormant conduction was mainly located around the bottom of both inferior PVs after CB-PVI. Multivariable analysis revealed that a longer time to the elimination of the PV potential (odds ratio 1.018; 95% confidence interval 1.001-1.036; P = .04) and the necessity of touch-up ablation (odds ratio 3.242; 95% confidence interval 2.761-7.111; P < .0001) were independently associated with the presence of dormant conduction after CB-PVI. After the elimination of dormant conduction by additional ablation, the AF-free rate was similar in patients with and without dormant conduction after both CB-PVI and RF-PVI (P = .28 and P = .73, respectively). CONCLUSION The results of the propensity score-matched analysis showed that dormant PV conduction was less frequent after CB ablation than after RF ablation and was not associated with ablation outcomes.
