Prevalence and Clinical Outcomes of Discordant Lesions Between Fractional Flow Reserve and Nonhyperemic Pressure Ratios in Clinical Practice: The J-PRIDE Registry.

Background: Limited large-scale, real-world data exist on the prevalence and clinical impact of discordance between fractional flow reserve (FFR) and nonhyperemic pressure ratios (NHPRs).

Methods: The J-PRIDE registry (Clinical Outcomes of Japanese Patients With Coronary Artery Disease Assessed by Resting Indices and Fractional Flow Reserve: A Prospective Multicenter Registry) prospectively enrolled 4304 lesions in 3200 patients from 20 Japanese centers. The lesions were classified into FFR+/NHPR-, FFR-/NHPR+, FFR+/NHPR+, or FFR-/NHPR groups according to cutoff values of 0.

Radiofrequency Catheter Ablation for Atrial Fibrillation Patients on Hemodialysis (From the Kansai Plus Atrial Fibrillation Registry) - Clinical Impact of Early Recurrence.

Background: Catheter ablation (CA) for atrial fibrillation (AF) in patients on hemodialysis (HD) is reported to have a high risk of late recurrence (LR). However, the relationship between early recurrence (ER) within a 90-day blanking period after CA in AF patients and LR in HD patients remains unclear.

Methods and results: Of the 5,010 patients in the Kansai Plus Atrial Fibrillation Registry, 5,009 were included in the present study.

Hypoxia-inducible factor-prolyl hydroxylase inhibitor Roxadustat (FG-4592) reduces renal fibrosis in Dahl salt-sensitive rats.

Objective: Although hypoxia-inducible factor-prolyl hydroxylase (HIF-PH) inhibitors have been developed for the treatment of renal anemia, their effects on cardiac and renal dysfunction remain unknown. We previously reported on Dahl salt-sensitive rats, in a rat model of salt-sensitive hypertension, that exhibited anemia and impaired expression of duodenal iron transporters after the development of hypertensive cardiac and renal dysfunction. Therefore, we investigated the effects of Roxadustat (FG-4592), an HIF-PH inhibitor, on anemia, iron regulation, and cardiac and renal dysfunction in Dahl salt-sensitive rats.

One Year Outcomes of Zilver PTX Versus Eluvia for Femoropopliteal Disease in Real-World Practice: REALDES Study.

Purpose: This multicenter, prospective, observational study aimed to compare Zilver PTX and Eluvia stents in real-world settings for treating femoropopliteal lesions as the differences in the 1-year outcomes of these stents have not been elucidated.

Materials And Methods: Overall, 200 limbs with native femoropopliteal artery disease were treated with Zilver PTX (96 limbs) or Eluvia (104 limbs) at 8 Japanese hospitals between February 2019 and September 2020. The primary outcome measure of this study was primary patency at 12 months, defined as a peak systolic velocity ratio of ≤2.

Enhancement patterns detected by multidetector computed tomography are associated with the long-term prognosis of patients with acute myocardial infarction.

The present study investigated the clinical value of myocardial contrast-delayed enhancement (DE) with multidetector computed tomography (MDCT) without iodine re-injection immediately after primary percutaneous coronary intervention (PCI) for predicting future cardiovascular events after acute myocardial infarction (AMI). We performed a prospective study in which 263 consecutive patients with first AMI successfully treated with primary PCI were enrolled. Sixty-four-slice MDCT without the re-injection of contrast medium was performed immediately after PCI.

Anterior chest wall regression after Nuss bar removal in adult patients with pectus excavatum.

Objective: Pectus excavatum repair with the Nuss procedure can be successfully performed in adults. After removing the pectus bars, the anterior chest wall may regress to some degree. The purpose of this study was to clarify the amount of improvement and regression of the chest wall after bar removal.

Analysis of chest wall elevation after the Nuss procedure using 3D body scanning technique in patients with pectus excavatum.

Purpose: For the evaluation of the chest wall deformity, we adopted a non-invasive 3D body scanning system. The objective of this study is to evaluate surgical effect on the whole thorax using 3D scanning technique before and after Nuss procedure.

Methods: We performed 3D body scanning using Structure Sensor (Occipital Inc, USA) in 11 symmetric patients (average age 13 ± 3.

[Usage of New Device to Prevent Sternum Separation after Median Sternotomy in 140 Cases].

While minimally invasive cardiac surgery (MICS) has become increasingly popular recently even in the field of cardiovascular surgery, the conventional full median sternotomy is still the main approach to the mediastinum, especially for cases which cannot be applied for MICS or in the facilities where MICS is not performed. It has been known that sternal instability is one of the leading causes of sternal infection after median sternotomy. Therefore, we have sought for an additional product to secure strong sternal stability.

Chondrotomy and sternotomy combined with the Nuss procedure for severe asymmetric pectus excavatum: how to do it.

The correction of severe asymmetric pectus excavatum is still challenging, especially for adults with a rigid thorax. For the repair of asymmetric cases, we introduce our surgical techniques added to the Nuss procedure. Chondrotomy of the depressed and deformed costal cartilage to elevate the depressed side was performed in a 42-year-old female patient.

Rib osteotomy with the Nuss procedure for the repair of adult pectus excavatum.

For the Nuss procedure in adult patients with pectus excavatum, sufficient sternal elevation is difficult due to the rigid chest wall. To solve the problem, we present a novel rib osteotomy procedure. From the skin incisions on the lateral chest which are the common approach for the Nuss procedure, a surgical drill is used to incise bilateral anterior half of the rib cortex after installing the pectus bars.

Severe obstructive sleep apnea is associated with coronary microvascular dysfunction and obstruction in patients with ST-elevation myocardial infarction.

Background: Coronary microvascular dysfunction and obstruction (CMVO) is a strong predictor of a poor prognosis in patients with ST-segment elevation myocardial infarction (STEMI). Although research has suggested that obstructive sleep apnea (OSA) exacerbates CMVO after primary percutaneous coronary intervention, data supporting a correlation between OSA and CMVO are limited. This study was performed to investigate whether OSA is associated with CMVO, detected as microvascular obstruction on cardiovascular magnetic resonance images, in patients with STEMI.

Cervicomedullary Ependymoma with Hemorrhage: A Case Report and Review of Literature.

Ependymoma is a rare tumor central nervous system that arises from the ependymal lining of the ventricles or the central canal of the spinal cord. They are of neuroectodermal in origin and constitute about 30%-86% of tumors arising in the spinal cord. The occurrence of these tumors in the cervicomedullary region is very rare.

Cardiovascular Outcomes in Patients With Previous Myocardial Infarction and Mild Diabetes Mellitus Following Treatment With Pioglitazone: Reports of a Randomised Trial From The Japan Working Group for the Assessment Whether ioglitazone rotects DM Patients gainst e-Infarction (PPAR Study).

Background: Secondary prevention in patients with myocardial infarction (MI) is critically important to prevent ischaemic heart failure and reduce social burden. Pioglitazone improves vascular dysfunction and prevents coronary atherosclerosis, mainly via anti-inflammatory and antiatherogenic effects by enhancing adiponectin production in addition to antihyperglycemic effects, thus suggesting that pioglitazone attenuates cardiovascular events in patients with mild (HbA1c levels < 6·5%) diabetes mellitus (DM). Therefore, we evaluated the effects of pioglitazone on cardiovascular events in patients with both previous MI and mild DM.

Methods: Between 1 July 2014 and 31 December 2015, we screened 2,359 patients (1,324 males) referred from 168 Japanese specialty clinics (cardiology, nephrology, neurology, and pediatrics), based on clinical symptoms suggestive of Fabry disease.

Does Treatment of Impaired Glucose Tolerance Improve Cardiovascular Outcomes in Patients with Previous Myocardial Infarction?

Purpose: We evaluated the effects of an alpha-glucosidase inhibitor, voglibose, on cardiovascular events in patients with a previous myocardial infarction (MI) and impaired glucose tolerance (IGT).

Methods: This prospective, randomized, open, blinded-endpoint study was conducted in 112 hospitals and clinics in Japan in 3000 subjects with both previous MI and IGT receiving voglibose (0.6 mg/day, n = 424) or no drugs (n = 435) for 2 years.

Mechanism of atrial functional mitral regurgitation in patients with atrial fibrillation: A study using three-dimensional transesophageal echocardiography.

Background: Functional mitral regurgitation (MR) can occur in patients with atrial fibrillation (AF) despite having preserved left ventricular (LV) systolic function. This MR is known as atrial functional MR. The aim of this study was to clarify the mechanism of atrial functional MR using real-time three-dimensional transesophageal echocardiography (3DTEE).

High-sensitive cardiac troponin T as a novel predictor for recurrence of atrial fibrillation after radiofrequency catheter ablation.

Aims: We aimed to determine whether elevated serum high-sensitive cardiac troponin T (hs-TnT) levels predict atrial fibrillation (AF) recurrence after pulmonary vein isolation (PVI).

Methods And Results: We included 125 consecutive patients with AF (paroxysmal, n = 79; persistent, n = 46) who underwent first-time PVI. Serum hs-TnT, high-sensitive C-reactive protein (hs-CRP), atrial natriuretic peptide, and plasma B-type natriuretic peptide levels were measured in venous samples collected before PVI.
