Background: Atrial fibrillation (AF) and heart failure (HF) often coexist, leading to increased mortality. A cryoballoon-based approach is a potential treatment for patients with HF because of its safety and efficacy.
Objectives: The authors sought to evaluate the optimal timing of cryoballoon ablation after the first clinical diagnosis of AF and its prognosis for patients with HF.
Introduction: The efficacy of catheter ablation in patients with low cardiac function has been previously reported; however, only a few studies have included mid-range ejection fraction (mrEF). This study aimed to evaluate the efficacy and safety of atrial fibrillation (AF) ablation in patients with left ventricular ejection fraction (LVEF) < 50%.
Methods: This study retrospectively analyzed 79 patients (reduced ejection fraction [rEF]/mrEF, 38/41; paroxysmal/persistent, 37/42; heart failure hospitalizations within one year before ablation, 36 [45.
We aimed to investigate the impact of post-discharge scheduled hospital visits on readmission due to heart failure (HF). In this retrospective study, a total of 245 patients (N = 101 in the scheduled hospital visit group, N = 144 in the non-scheduled hospital visit group) who were alive with free from readmission due to HF for 90 days after discharge were enrolled. The patients had been hospitalized with acute decompensated HF between August 2018 and July 2019.

However, the pathophysiological substrate of LA-CV and its impact on outcomes after catheter ablation for AF have not been well evaluated.
Methods: We retrospectively evaluated 119 patients with AF who underwent catheter ablation and electroanatomical mapping during sinus rhythm.
Introduction: Data are limited regarding outcomes of cryoballoon ablation for atrial fibrillation (AF) in patients with heart failure (HF). This large-scale multicenter study aimed to evaluate the prognosis of patients with HF after cryoballoon ablation for AF.
Methods: Among 3655 patients undergoing cryoballoon ablation at 17 institutions, 549 patients (15%) (391 with paroxysmal AF and 158 with persistent AF) diagnosed with HF preoperatively were analyzed.
P-wave morphology reflects atrial remodeling and indicates prognosis after radiofrequency catheter ablation (RFCA) for atrial fibrillation (AF). The impact of p-wave morphology after excluding the effect of pulmonary vein (PV) substrate on outcomes is unknown. We evaluated the p-wave morphology on electrocardiography immediately after PV isolation for clinical outcomes.

The study subjects comprised 253 hospitalized patients with ADHF. The controlling nutritional status (CONUT) score was assessed both at hospital admission and discharge.

Background: Uninterrupted DOAC used during catheter ablation for AF causes a life-threatening bleeding risk of cardiac tamponade.
Methods: Of 3,149 catheter ablation procedures for AF with uninterrupted oral anticoagulants used in 2,406 patients in 3 institutions, DOAC and warfarin were administered in 1,896 and 1,253 procedures, respectively.
The purpose of the study was to evaluate the impact of nutritional status on 1-year mortality in hospitalized patients with acute decompensated heart failure (ADHF). We enrolled 457 hospitalized ADHF patients. Previously established objective nutritional indexes (controlling nutritional status [CONUT], prognostic nutritional index [PNI], geriatric nutritional risk index [GNRI], and subjective global assessment [SGA]) were evaluated at hospital admission.

Although several case reports on their diagnosis and treatment have been published, those on hemorrhagic pericardial cysts remain limited. We herein report the case of a 70-year-old man with a hemorrhagic pericardial cyst complicated with constrictive pericarditis 2 years after the initial diagnosis.

However, little is known about the safety and efficacy of uninterrupted dabigatran therapy in patients undergoing CA for AF. Therefore, this study investigated the safety and efficacy of uninterrupted dabigatran therapy and compared the findings with those for uninterrupted warfarin therapy.

Introduction: Apixaban, a factor Xa (FXa) inhibitor, is a new oral anticoagulant for stroke prevention in atrial fibrillation (AF). However, little is known about its efficacy and safety as a periprocedural anticoagulant therapy for patients who had undergone catheter ablation (CA) for AF.
Methods And Results: We evaluated 342 consecutive patients who underwent CA for AF between April 2013 and March 2014 and received apixaban (n = 105) and warfarin (n = 237) for uninterrupted periprocedural anticoagulation.
Background & Aims: Roles of alcohol consumption in non-alcoholic fatty liver disease are still controversial, although several cross-sectional studies have suggested the beneficial effect of light to moderate drinking on fatty liver. We analyzed the longitudinal relationship between drinking pattern and fatty liver.
Methods: We included 5297 Japanese individuals (3773 men and 1524 women) who underwent a baseline study in 2003 and follow-up at least once from 2004 to 2006.
Background: Patients with greater improvement of cardiac function after cardiac resynchronization therapy (CRT) implantation are identified as "super-responders." However, it remains unclear which kind of preimplant assessments could accurately predict outcomes after CRT. Thus, we aimed to examine the essential predicting factors for super-response to CRT, and to construct an accurate predictable model.

However, little is known about the performance of these leads in Asian patients. The aim of this study was to investigate the rate of failure of the recalled leads and the characteristics as compared with non-recalled leads in Japanese patients.

The increasing elderly population will influence the treatment policies adopted in cases of acute myocardial infarction. Considering reperfusion therapy in elderly patients with acute myocardial infarction, we compared three strategies, as follows: primary percutaneous coronary intervention (primary PCI: n = 26), facilitated PCI with half the standard dose of mutant tissue-type plasminogen activator (t-PA) (half + PCI: n = 24), and facilitated PCI with a standard dose of mutant t-PA (standard + PCI: n = 15) between patients 75 and 80 years of age. The rate of acquisition of thrombolysis in myocardial infarction (TIMI-3) flow on initial coronary arteriography was significantly lower in the primary PCI group than in the other two groups (7.

For an approach of gene therapy for hepatocellular carcinoma (HCC), transcriptional regulatory sequence (TRS) of either alpha-fetoprotein (AFP) or albumin has been used for targeting cancer cells. To examine the feasibility of using TRSs of these genes for possible gene therapy of HCCs, the cellular distribution of AFP and albumin gene transcripts was studied in 25 cases of surgically removed human HCCs. AFP gene expression was observed in HCC nodules of 13 cases.

Material And Methods: Twenty eight HCC patients who had received PEIT were divided into 3 groups. The non-recurrence (NR) group in which no new lesions were observed for at least 18 months after PEIT (13 patients), the early recurrence group (ER) in which lesions recurred within one year (6 patients), and the late recurrence group (LR) in which lesions recurred more than one year after PEIT (9 patients).
To examine the possible involvement of gelatinase B in human hepatocellular carcinoma (HCC), cellular localization of transcripts and protein of gelatinase B were studied by using in situ hybridization and immunohistochemistry. Transcripts for gelatinase B were observed in tumor cells in 22 cases of 27 HCCs and also in dysplastic nodules. However, there was no significant difference in the expression among histological grades of HCC.

Liver specimens were obtained after intravenous ICG injection by ultrasound-guided biopsy from 251 space-occupying lesions (SOL) in 136 patients. The tissues were immediately examined for ICG uptake using an infrared Vidicon camera and were also subjected to histopathological examinations.
