[Two-staged Operation for Bilateral Giant Bullae Successfully Performed with Veno-venous Extracorporeal Membrane Oxygenation( V-V ECMO) for First Surgery].

57-year-old man with bilateral giant lung bullae was admitted to our hospital for dyspnea on exertion as his chief complaint. The size and shape of right lung bullae were bigger and more complicated than those of left lung bullae. He underwent 2-staged bullectomy by video-assisted thoracoscopic surgery (VATS).

Marshall bundle reentrant atrial tachycardia after the Cox-Maze IV procedure: The last barrier of the conduction pathway between the coronary sinus and left atrium.

A 74-year-old woman who developed atrial tachycardia following the Cox-Maze IV procedure underwent catheter ablation. The reentrant circuit included the coronary sinus (CS), Marshall bundle (MB), distal MB-left atrial (LA) connection, and anterolateral mitral annulus. The distal MB-LA connection was the last barrier in the conduction pathway between the CS and the left atrium.

Clinical background including anticoagulant therapy in patients with atrial fibrillation in a community-based survey: the Saitama AF Registry.

Atrial fibrillation (AF) is one of the most common cardiac arrhythmias, and carries an increased risk of cardiogenic embolism. Oral anticoagulants (OACs) including warfarin and/or non-vitamin K antagonists can prevent the majority of these events. The Saitama AF Registry was a community-based survey of patients with AF in Saitama City, which represents an urban community in Japan.

Peri-Mitral Atrial Tachycardia Using the Marshall Bundle Epicardial Connections.

Objectives: The aim of this study was to determine whether re-entrant circuits were associated with the ligament of Marshall (LOM).

Background: Peri-mitral atrial tachycardias (PMATs) following pulmonary vein isolation (PVI) or mitral valve surgery are common.

Methods: Six PMATs involving epicardial circuits were identified from 38 patients.

Lower 1,5-anhydroglucitol is associated with adverse clinical events after percutaneous coronary intervention.

Diabetes mellitus and impaired glucose tolerance are well-known risk factors for coronary artery disease (CAD) and adverse clinical events after percutaneous coronary intervention (PCI). Postprandial hyperglycemia is an important risk factor for CAD and serum 1,5-anhydroglucitol (1,5-AG) reflects postprandial hyperglycemia more robustly than hemoglobin (Hb)A1c. We aimed to clarify the relationship between serum 1,5-AG level and adverse clinical events after PCI.

Circadian variation of acute aortic dissection.

Acute aortic dissection (AAD) is a life-threatening cardiovascular disease with high mortality. Hypertension is a well known risk factor of AAD. There have been previous reports about the association between circadian variation of blood pressure (BP) and cardiovascular events.

Prognosis of patients with fulminant myocarditis managed by peripheral venoarterial extracorporeal membranous oxygenation support: a retrospective single-center study.

Background: Peripheral venoarterial extracorporeal membranous oxygenation (ECMO) support is effective in patients with cardiogenic shock or fatal arrhythmia due to fulminant myocarditis. The clinical courses of fulminant myocarditis are still uncertain; therefore, it is difficult to determine the appropriate time for discontinuing ECMO or converting to a ventricular assist device. The purpose of this study was to investigate the prognosis of patients with fulminant myocarditis managed by ECMO.

Cardiovascular and bleeding risk of non-cardiac surgery in patients on antiplatelet therapy.

Background: The perioperative risk of non-cardiac surgery (NCS) in the patients on antiplatelet therapy after percutaneous coronary intervention (PCI) remains unclear.

Methods: This study was a retrospective and single center study. Between January 2008 and December 2011, 198 patients who had already received PCI underwent NCS in our hospital.

Lower 1,5-anhydroglucitol is associated with denovo coronary artery disease in patients at high cardiovascular risk.

Postprandial hyperglycemia is a risk factor for cardiovascular disease and mortality. Serum 1,5-anhydroglucitol (1,5-AG) level is an useful clinical marker of glucose metabolism which reflects postprandial hyperglycemia more robustly compared to hemoglobin A1c (HbA1c). Relationship between serum 1,5-AG level and cardiovascular disease has been reported; however, comparison between HbA1c and 1,5-AG as markers of cardiovascular disease was not performed.

Effect of chronic statin treatment on vascular remodeling determined by intravascular ultrasound in patients with acute myocardial infarction.

Early statin treatment of patients with acute coronary syndrome results in vascular changes and improved clinical outcomes. However, the influence of chronic statin treatment on the culprit vessel in acute coronary syndrome is not fully understood. The aim of this study was to investigate the morphologic features of the culprit vessel in acute myocardial infarction by comparing patients with and without chronic statin treatment.

Clinical features of infective endocarditis: comparison between the 1990s and 2000s.

Background: The circumstances surrounding infective endocarditis (IE) are under constant change due to an increase in drug-resistant organisms, a decrease in rheumatic valve disease, progress in surgical treatment, and aging society. The purpose of this study was to compare clinical features of IE between the 1990s and 2000s and to elucidate the determinants of death or clinical event.

Methods: All hospital admission records between January 1990 and December 2009 were retrospectively analyzed.

Clinical features of myocardial infarction in young Japanese patients.

Clinical features and outcomes of acute myocardial infarction (AMI) in the young have been poorly investigated. The aim of this study was to investigate the clinical features and hospital outcomes of AMI in young Japanese. We conducted a case-control study.

Pulmonary hypertension in a patient with intravascular lymphomatosis.

Intravascular lymphomatosis (IVL) is a rare subtype of lymphoma characterized by proliferation of lymphoma cells into small vessels. Clinical presentations of IVL are considerably varied among patients, and antemortem diagnosis is sometimes difficult. We report a 75-year-old Japanese female who presented with gradually worsening shortness of breath and pulmonary hypertension.

Contrast induced exacerbation of renal dysfunction in the advanced chronic kidney disease.

Contrast media affects renal function, especially in the patients with advanced chronic kidney disease (CKD). The aim of this study was to investigate the characteristics of contrast induced exacerbation of renal dysfunction in the patients with advanced CKD (estimated glomerular filtration rate <30 ml/min/1.73 m(2)).

Fractional flow reserve for a mild stenosis on the donor artery to chronic total occlusion.

Fractional flow reserve (FFR) is considered as the gold standard for physiological assessment of coronary artery stenosis. However, it may be difficult to interpret FFR for the stenosis of the donor artery of chronic total occlusion (CTO), because revascularization of CTO may improve FFR of the donor artery. We present a case of 32-year-old male who had a CTO in right coronary artery (RCA), 90% stenoses in left circumflex artery (LCx) and a mild stenosis in the middle segment of left anterior descending artery (LAD).
