Double-chambered left ventricle as a novel cause of aneurysm formation at the apex of accessory chamber.

This case report shows unique aneurysm at the left ventricular apex associated with a double-chambered left ventricle (DCLV) in asymptomatic 69-year-old female. The aneurysm was located at the apex of an accessory chamber, which was formed by hypertrophied muscle band and the interventricular septum, along with a pronounced jet flow directed towards the apex aneurysm. These finding suggests that the obstruction at the base of the accessory chamber caused a pressure overload at the apex, ultimately leading to the development of the aneurysm.

Predictors of Irregular Protrusion After Everolimus-Eluting Stent Implantation in Patients with Stable Coronary Artery Disease.

This study aimed to investigate clinical and preintervention optical coherence tomography (OCT) findings to predict irregular protrusion (IRP) immediately after stent implantation.We evaluated 84 lesions treated with cobalt-chromium everolimus-eluting stent (CoCr-EES) from the MECHANISM Elective study. Patients were divided into two groups according to the presence of IRP [IRP: n = 16, non-IRP: n = 68].

Comparison of serial optical coherence tomography imaging following aggressive stent expansion technique: insight from the MECHANISM study.

To compare early vascular healing following cobalt-chromium everolimus-eluting stent (CoCr-EES) implantation between groups with or without aggressive stent expansion in patients treated by CoCr-EES for stable coronary artery disease (CAD). Seventy-one stable CAD lesions underwent CoCr-EES implantation and analysis of serial optical coherence tomography (OCT) images obtained post-procedure and at early-term (1- or 3-month) follow-up. The endpoints of this study were neointimal thickness at the time of 1- or 3-month OCT and presence and healing of stent edge dissection.

Cut-off value of strut-vessel distance for the resolution of acute incomplete stent apposition in the early phase using serial optical coherence tomography after cobalt-chromium everolimus-eluting stent implantation.

Objective: The purpose of this study was to identify a cut-off value to predict the resolution of incomplete-stent-apposition (ISA) after cobalt-chromium everolimus-eluting stent (CoCr-EES) implantation at early follow-up.

Background: To date, appropriate stent apposition at the acute period using intracoronary imaging has been recommended because persistent ISA is considered to be a risk factor for stent thrombosis. We examined the indices for resolving acute ISA.

Cut-off value of mal-apposition volume and depth for resolution at early phase of acute incomplete stent apposition after CoCr-EES implantation.

The purpose of this study was to clarify a cut-off value for acute incomplete stent apposition (ISA) volume and maximum-depth to predict ISA resolution at 1- and 3-month follow-up in patients treated with cobalt-chromium everolimus-eluting stents. In total, 95 cases and 103 stents were registered in the MECHANISM-Elective sub-study. Acute ISA-volume was measured by the trapezoid rule.

CHADS and modified CHADS-VASc scores for the prediction of congestive heart failure in patients with nonvalvular atrial fibrillation.

Background & Purpose: We have conducted a retrospective observational study to analyze the correlation between the CHADS score, the modified CHADS-VASc (mCHADS-VASc) score, and the incidence of all-cause death and congestive heart failure (CHF).

Methods: The study cohort consisted of 292 consecutive patients with nonvalvular atrial fibrillation (NVAF) admitted to our hospital from 2012 to 2014. Electronic medical records were used to confirm medical history including prior heart failure, hypertension, diabetes, stroke, and coronary disease.

Coronary risk factors associated with OCT macrophage images and their response after CoCr everolimus-eluting stent implantation in patients with stable coronary artery disease.

Background And Aims: The aim of this study was to evaluate the accumulation of optical coherence tomography (OCT)-macrophages and OCT findings after CoCr everolimus-eluting stent placement, in addition to coronary risk factors.

Methods: A total of 89 lesions in 89 patients were registered in the 1- and 3-month cohort of the multi-centre study. Lesion characteristics and post-procedure OCT images were evaluated immediately and 1 and 3 months after stenting.
