Coronavirus Disease 2019 (COVID-19) Information for Cardiologists - Systematic Literature Review and Additional Analysis.

Background: Despite the rapidly increasing attention being given to Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection, more commonly known as coronavirus disease 2019 (COVID-19), the relationship between cardiovascular disease and COVID-19 has not been fully described.

Methods and results: A systematic review was undertaken to summarize the important aspects of COVID-19 for cardiologists. Protection both for patients and healthcare providers, indication for treatments, collaboration with other departments and hospitals, and regular update of information are essentials to front COVID-19 patients.

Identification of Left Atrial Appendage Thrombi in Patients With Persistent and Long-Standing Persistent Atrial Fibrillation Using Intra-Cardiac Echocardiography and Cardiac Computed Tomography.

Background: Intracardiac echocardiography (ICE) and cardiac computed tomography (CCT), in addition to standard transesophageal echocardiography (TEE), have been used to identify left atrial (LA) thrombi prior to ablation for atrial fibrillation (AF). The clinical advantages of this, however, remain unclear. This study therefore investigated the advantages of additional pre-procedural LA appendage (LAA) thrombus evaluation using ICE and the clinical value of CCT in persistent and long-standing persistent AF.

Prognostic values of blood pH and lactate levels in patients resuscitated from out-of-hospital cardiac arrest.

Aim: Early prediction of prognosis after out-of-hospital cardiac arrest (OHCA) remains difficult. High blood lactate or low pH levels may be associated with poor prognosis in OHCA patients, but these associations remain controversial. We compared blood lactate and pH levels in OHCA patients transferred to our hospital to measure their prognostic performance.

Outcomes of Percutaneous Coronary Intervention Performed With or Without Preprocedural Dual Antiplatelet Therapy.

Background: Preprocedural dual antiplatelet therapy (DAPT) in percutaneous coronary interventions (PCI) has been shown to improve outcomes; however, the efficacy of the procedure and its complications in Japanese patients remain largely unexplored, so we examined the risks and benefits of DAPT before PCI and its association with in-hospital outcomes.

Methods and results: We analyzed data from patients who had undergone PCI at 12 centers within the metropolitan Tokyo area between September 2008 and September 2013.Our study group comprised 6,528 patients, of whom 2,079 (31.

Efficacy of tolvaptan in a patient with right-sided heart failure and renal dysfunction refractory to diuretic therapy.

The use of loop diuretics has been shown to deteriorate renal dysfunction and is associated with a poor prognosis in patients with heart failure (HF). Tolvaptan, a vasopressin V2-receptor antagonist, has been reported to be effective in treating HF due to its potent effects of water diuresis and is expected to improve fluid retention without adversely affecting renal function. The present case is a 77-year-old man with pulmonary hypertension associated with chronic pulmonary artery thrombosis and old pulmonary tuberculosis who developed worsening right-sided HF with marked fluid retention and renal dysfunction.

Primary aldosteronism associated with a giant coronary aneurysm after drug-eluting stent implantation.

Although primary aldosteronism had been recognized to be a treatable type of hypertension, it was recently suggested to be associated with an increased risk of cardiovascular complications. Coronary artery aneurysm is a rare complication after drug-eluting stent (DES) implantation, and a giant coronary aneurysm is very rare. The present case is a 51-year-old, hypertensive patient with primary aldosteronism who developed myocardial infarction, a giant coronary aneurysm after DES implantation, and then cerebral hemorrhage.

Report from the Japanese registry of CPR for in-hospital cardiac arrest (J-RCPR).

Background: In-hospital cardiopulmonary arrest (CPA) is an important issue, but data in Japan are limited.

Methods And Results: To investigate in-hospital CPA, we conducted a prospective multicenter observational registry of in-hospital CPA and resuscitation in Japan (J-RCPR). During January 2008 to December 2009, patients were registered from 12 participating hospitals.

Usefulness of a second temporary vena cava filter for preventing acute pulmonary thromboembolism.

The usefulness of a temporary inferior vena cava filter (t-IVC-f) for the prevention of acute pulmonary thromboembolism (APTE) associated with venous thromboembolism (VTE) has been established, but not the requirement for an additional therapeutic method when the t-IVC-f has captured a thrombus. A woman underwent implantation of a t-IVC-f just caudal to the bifurcation of the renal vein immediately before cesarean section (C/S) for VTE that had occurred during the third trimester of pregnancy. After receiving a combination of anticoagulant and fibrinolytic therapies after the C/S, the t-IVC-f was found to contain a thrombus and in order to prevent its dissemination during the removal of the closed filter, another filter was inserted and expanded proximal to the first.
