Primary Cardiac Lymphoma With Dramatic Response to Chemotherapy Diagnosed by Transvenous Biopsy.

Primary cardiac lymphoma is a rare disease with the potential to be fatal. This case reports a patient who developed primary cardiac lymphoma resulting in cardiac tamponade. Despite a compromised general condition, the lymphoma was diagnosed through a transvenous tumor biopsy.

The impact of lesion complexity on predicting mortality of coronary artery disease patients after out-of-hospital cardiac arrest.

Introduction: Coronary artery disease (CAD) is the most frequent cause of out-of-hospital cardiac arrest (OHCA). Nevertheless, there have been limited studies focusing on the impact of lesion complexity on resuscitated CAD patients. The purpose of the present study was to investigate the association between coronary lesion complexity and the mortality of CAD patients after OHCA.

Catheter ablation for atrial fibrillation in patients with congestive heart failure.

Background: We evaluated the 1-year success rate of maintaining sinus rhythm after catheter ablation (CA) for atrial fibrillation (AF) in patients with or without congestive heart failure (CHF).

Methods: In this single-centre retrospective matched-pair cohort study of 3,018 AF patients who underwent initial CA between January 2012 and June 2018, 227 pairs with (CHF group) or without CHF (control group) were matched using propensity scores. In the CHF group, 108 patients were assigned to the arrhythmia-induced cardiomyopathy (AIC) group whose left ventricular systolic dysfunction was explained only by lasting AF or atrial tachycardia; the remaining 119 had organic heart diseases (non-AIC group).

Effectiveness of Bare Metal Stent Implantation for the Treatment of Coronary Artery Aneurysm: A Multimodality Imaging Evaluation.

Coronary artery aneurysm (CAA) after sirolimus-eluting stent (SES) implantation is one of the most troublesome problems associated with first-generation drug-eluting stents. However, the natural course and standard therapy of CAA has been unknown. A 49-year-old man underwent SES implantation for the left anterior descending artery.
