Microporous polysaccharide hemospheres for reducing pocket hematomas after cardiac device implantation in patients on antithrombotic therapy.

Background: Various surgical procedures have employed microporous polysaccharide hemosphere (MPH) hemostatic agents. However, data regarding their effectiveness in preventing pocket hematomas (PHs) during the implantation of cardiac implantable electronic devices (CIED) among the Asian population are limited. Therefore, this study aimed to investigate the potential benefits of using MPH hemostatic agents during CIED implantations as a preventive measure against post-procedural PHs.

A case report of undetected cardiac arrest in a patient with an insertable cardiac monitor.

Unlabelled: Insertable cardiac monitors (ICMs) are small electrocardiographs implanted subcutaneously to automatically record electrocardiograms when arrhythmia is detected in patients with syncope. If the ICM misses a significant arrhythmia, it may delay the diagnosis of arrhythmogenic syncope and put the patient at risk. Herein, we describe a case of undetected cardiac arrest in a patient with ICM.

Semi-urgent pulmonary vein isolation using cryoballoon for haemodynamically unstable atrial fibrillation storm in a patient with low cardiac output syndrome: a case report.

Background: Atrial fibrillation and heart failure are common coexisting conditions requiring hospitalisation for heart failure and death. Pulmonary vein isolation is a well-established option for symptomatic atrial fibrillation and for atrial fibrillation concomitant with heart failure with reduced left ventricular ejection fraction. Recently, pulmonary vein isolation using cryoballoon showed non-inferiority to radiofrequency ablation with respect to the treatment of patients with drug-refractory paroxysmal atrial fibrillation.

B-type natriuretic peptide and risk of sudden death in patients with hypertrophic cardiomyopathy.

Background: The association between B-type natriuretic peptide (BNP) levels and sudden cardiac death in patients with hypertrophic cardiomyopathy (HCM) remains unclear.

Objective: This study evaluated the effect of elevated BNP levels on sudden death risk in a cohort of patients with HCM.

Methods: This study included 346 patients with HCM.

Association of elevated pulmonary artery systolic pressure with stroke and systemic embolic events in patients with hypertrophic cardiomyopathy.

Background: Echocardiographically estimated pulmonary artery systolic pressure (PASP) is a non-invasive widely available method that is used to estimate pulmonary arterial pressure. Although elevated PASP predicts mortality in patients with hypertrophic cardiomyopathy (HCM), the relationship between PASP and embolic events is unclear. This study aimed to determine whether elevated PASP is associated with stroke and systemic embolic events in a tertiary referral HCM cohort.

Implantable cardioverter defibrillator therapy and sudden death risk stratification in hypertrophic cardiomyopathy patients with midventricular obstruction: A single-center experience.

Background: Previous studies reported that the presence of midventricular obstruction (MVO) was an independent determinant of sudden death and potentially lethal arrhythmic events in patients with hypertrophic cardiomyopathy (HCM). However, it remains unclear whether implantable cardioverter defibrillator (ICD) improves survival in HCM patients with MVO. In addition, the risk factors for lethal arrhythmic events in MVO-HCM patients are not fully understood.
