Subclinical and latent cardiac dysfunction in obstructive sleep apnea and effectiveness of continuous positive airway pressure.

Purpose: Obstructive sleep apnea (OSA) is associated with various cardiovascular disorders. This study aimed to investigate the effects of OSA on left ventricular (LV) function in patients with OSA who were at risk for heart failure but who had not yet developed structural heart changes. The study also sought to determine the effects of continuous positive airway pressure (CPAP) in these patients.

Acute Myocardial Infarction Due to Coronary Artery Embolism during Chemotherapy with mFOLFOX-6 Plus Bevacizumab for Metastatic Colon Cancer.

Bevacizumab, a monoclonal antibody against vascular endothelial growth factor, may be associated with arterial embolisms. We herein report a case of acute myocardial infarction caused by coronary embolism during combination chemotherapy with mFOLFOX-6 and bevacizumab in a patient with metastatic colon cancer. Thromboembolism occurred only in the distal right posterolateral branch without stenotic lesions or plaque rupture in the proximal branch of the right coronary artery.

Emergency Transcatheter Aortic Valve Implantation in a Surgical Aortic Bioprosthetic Valve for Acute Decompensated Heart Failure Caused by Sudden Progression of Structural Valve Deterioration.

Bioprosthetic aortic valves have limited durability. We herein report sudden progression of structural valve deterioration (SVD) and a successful case of emergency transcatheter aortic valve (TAV) implantation for acute decompensated heart failure (ADHF) caused by SVD. A 79-year-old man who had undergone a Bentall operation 11 years prior was diagnosed with ADHF due to suddenly progressive SVD.

Difficulty Diagnosing Retrograde Type A Aortic Dissection with Intramural Hematoma and Risk of Re-dissection and Rupture: A Report of Two Cases.

Acute type A aortic dissection is a potentially fatal disease, and emergency surgery should be considered when it is diagnosed. We herein report two cases of retrograde type A aortic dissection with intramural hematoma, followed by re-dissection, rupture, and cardiac tamponade. The diagnoses in these cases had to be made carefully, as the false lumen of the ascending aorta was sometimes unclear on contrast-enhanced computed tomography.

Clinical feasibility of pulmonary vein orifice pacing for the prediction of phrenic nerve injury during cryoballoon ablation of atrial fibrillation.

Introduction: Phrenic nerve (PN) injury is a well-known complication of cryoballoon ablation (CBA) for pulmonary vein (PV) isolation in patients with atrial fibrillation. However, it is still insufficient to practically predict phrenic nerve injury (PNI) before freezing. We hypothesized that phrenic nerve capture (PNC) with phrenic nerve orifice pacing (PVOP) might be a surrogate sign of the close proximity of the PN, and that might predict PNI and changes in the compound motor action potential (CMAP) amplitude.

Effectiveness of plasma lyso-Gb3 as a biomarker for selecting high-risk patients with Fabry disease from multispecialty clinics for genetic analysis.

Purpose: Plasma globotriaosylsphingosine (lyso-Gb3) is a promising secondary screening biomarker for Fabry disease. Here, we examined its applicability as a primary screening biomarker for classic and late-onset Fabry disease in males and females.

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.

The Diagnosis of Spontaneous Coronary Artery Dissection by Optical Coherence Tomography.

Spontaneous coronary artery dissection (SCAD) is rare, but it frequently presents as acute myocardial infarction. It is frequently fatal and most cases are diagnosed at autopsy. We herein present the case of a 65-year-old woman with ST-elevation and myocardial infarction due to SCAD.

A case of ventricular septal rupture associated with major septal branch occlusion after percutaneous coronary intervention.

A 67-year-old man underwent elective percutaneous coronary intervention (PCI) of the left anterior descending artery. The major septal branch became occluded during coronary stenting. The patient developed dyspnea 19 days later.
