anomalies of origin, course, and distribution of coronary arteries, including single coronary artery, are well known in patients with tetralogy of fallot. however, to the best of our knowledge, there is no published case report of pentalogy of fallot with a single coronary artery. herein, we introduce a 22-year-old female patient diagnosed via echocardiography and cardiac catheterization preope...

a 48-year-old woman was admitted to the emergency department with complaints of typical chest pain, cold sweat, and dyspnea of 24 hours’ duration. she had a history of hypertension, hyperlipidemia, and diabetes mellitus for many years. on admission, her electrocardiogram (ecg) revealed normal sinus rhythm and dynamic t inversion in the precordial leads. her enzyme levels were normal. transthora...

Vessel speed and heading are two important kinematic parameters describing its state of motion. However, due to low spatial resolution a compact high-frequency surface wave radar (HFSWR), vessel cannot always be accurately estimated. Since HFSWR can measure Doppler velocity with relatively high accuracy, it is possible estimate vessel's vector based on velocities measured along different direct...

Methods The R-US trial recruited patients with de novo native coronary lesions suitable for 1or 2-vessel treatment with stents from 2.25 to 4.0 mm in diameter. In the main analysis cohort (2.5to 3.5-mm stents and single-lesion treatment), the primary endpoint was 12-month target lesion failure (TLF) defined as the composite of cardiac death, myocardial infarction (MI), and clinically-driven tar...

Commentary The optimal management of patients who need long-term oral anticoagulation and coronary stenting is unknown. Bleeding risks are substantial with triple oral anticoagulation therapy using an oral anticoagulant plus aspirin and clopidogrel for antiplatelet therapy. The WOEST trial showed a reduction in the primary endpoint of any bleeding in patients who received double therapy (oral a...

OBJECTIVE To make a prospective assessment of the clinical and prognostic correlates of angiographically diffuse non-obstructive coronary lesions. DESIGN Angiographic vessel and extent scores were calculated in 228 clinically stable patients (mean (SD) age, 60 (11) years; 43 women, 185 men) undergoing prospective follow up for the composite end point of death and myocardial infarction. The ef...

BACKGROUND AND OBJECTIVES The effectiveness of adjunct balloon dilation after drug-eluting stent (DES) deployment has not been sufficiently evaluated. We evaluated whether adjunct balloon dilation was associated with a reduction in major adverse cardiac events (MACEs) after long everolimus-eluting stents (EESs) implantation. SUBJECTS AND METHODS Drawing from 2 randomized trials, a total of 1,...

Methods We randomly assigned 2,117 patients with coronary artery stenosis into 2 groups according to DAPT duration and stent type: 3-month DAPT following Endeavor zotarolimus-eluting stent (E-ZES) implantation (E-ZES 3-month DAPT, n 1,059) versus 12-month DAPT following the other DES implantation (standard therapy, n 1,058). We hypothesized that the E-ZES 3-month DAPT would be noninferior to th...

Large costs arise at a seaport container terminal from the duration of the unloading of vessels and from the time a vessel is waiting to be unloaded. The optimal allocation of vessels to berth space (Berth Allocation Problem) becomes more and more important as its solution is also input to further terminal decision problems. We compare solutions for a realistic data Berth Allocation Problem fou...
