Newer bileaflet mechanical heart valves require lower doses of oral anticoagulants to avoid valve thrombosis and embolism genesis. However, little is known about the safety of low-dose regimens in pregnant women who have a hypercoagulable state, yet warfarin embryopathy is known to be dose related.

It is well known that the risk of perioperative major adverse cardiac events (MACE) is high in patients with coronary stents, especially early after stent implantation.

The Riata and Riata ST ICD leads manufactured by St. Jude Medical have recently come under increased scrutiny because of the observation that the conductor cables could extrude from the outer insulation.

This study reports data from the International Collaboration on Endocarditis-Prospective Cohort Study (ICE-PCS) on the clinical characteristics of infective endocarditis related to pacemakers and ICDs.

Medical therapy is the mainstay of treatment for coronary artery disease (CAD), resulting in improved clinical outcomes. Revascularization with percutaneous coronary intervention (PCI), in addition to medical therapy, improves symptoms in patients with stable CAD.

Concentric left ventricular hypertrophy (CLVH) is occasionally unexplained. Thus, these investigators from Beijing, China, sought evidence for Danon disease, a glycogen storage disease, in patients being evaluated for cLVH who underwent endomyocardial biopsy.

In this paper, the authors performed a pharmacoepidemiologic study on the relationship between azithromycin, a frequently used broad-spectrum macrolide antibiotic, and cardiovascular death. The authors analyzed data from the Tennessee Medicaid program. This database provides information on medical care encounters and dates and causes of death and is linked to death certificates and hospital discharge data.

These investigators from Australia present a case of isolated left ventricular (LV) apical hypoplasia with fatty infiltration confirmed by CT and MRI. The left anterior descending artery was small and truncated early on angiography. Echocardiography showed a large banana-shaped right ventricle (RV) that wrapped around the apex of the hypocontractile truncated LV. Also there was apical papillary muscle insertion.
