    Abstract Intra-aortic balloon pump is an invasive procedure used in critically unwell population and carries risks of possible complications. The most common complications include thrombocytopenia and fever, occurring approximately 50 and 36% of the time. Rare complications include vascular tears, limb ischemia, occurring approximately 1-2% of the time and balloon rupture and/or entrapment approximately 0.5% of the time. Current literature suggests the most common etiology of entrapment is due to balloon rupture and the formation of clot within the balloon causing difficulty in removal. Herein, we demonstrate a case series of intra-aortic balloon pump entrapment without balloon rupture.

    Abstract Chronic mesenteric ischemia has traditionally been treated with either open surgical revascularization or endovascular therapy. Endovascular surgery has typically been preferred due to the lower rates of peri-procedural and post-procedural morbidity, yet this comes at the expense of long-term durability. Intravascular shockwave lithotripsy is a technique utilized to modify intimal and medial calcified plaque in order to improve vessel expansion and patency. Intravascular lithotripsy has been investigated as both primary and adjunctive treatment for peripheral arterial and coronary arterial lesions, however, its use in the treatment of chronic mesenteric ischemia requires further investigation. We present a case of a 75-year-old woman with symptomatic mesenteric ischemia who underwent intravascular shockwave lithotripsy of a 99% stenosis superior mesenteric artery with an excellent outcome.

    Abstract Aortic valve replacement has long been the standard of care for many aortic valve diseases. Neo sinus reconstruction and aortic valve reconstruction with native pericardium, known as the Ozaki procedure, is a relatively new technique with early studies showing good mid-term durability and hemodynamics without the need for life-long anticoagulation. We present the case of a 56-year-old male presenting with aortic valve endocarditis and severe aortic insufficiency who underwent successful aortic valve reconstruction via the Ozaki procedure complicated by postpericardiotomy syndrome and cardiac tamponade. Although the Ozaki procedure is a promising alternative to conventional aortic valve replacement, further study is needed to determine long-term re-operation rates, stability and mortality.

    Abstract Techniques for vascular intervention have been evolving in the past decades. Trans-radial artery access (TRA) has been emerging and is favorable over trans-femoral access in recent years due to the lower risk of bleeding complications, vascular injury, early mobilization, shorter hospitalization and lesser cost. TRA has its own limitations such as radial artery stenosis, dissection, spasm and crossover. When access from the conventional sites is complicated or unsuccessful, trans-ulnar artery may serve as a feasible and alternative route. Despite posing potential complications similar to TRA, trans-ulnar artery is a relatively safe approach in an experienced trans-radial operator. We, herein, present a challenging case of subclavian artery revascularization performed via retrograde trans-ulnar approach.

    Abstract Objective: We sought to investigate mid-term clinical outcomes and identify risk factors in one of the largest comprehensive series reported of femoro-ilio-caval (FIC) vein stent placement.
    Background: Endovascular intervention with balloon angioplasty and stenting of the iliac and common femoral veins has become first-line treatment for symptomatic deep venous outflow obstruction.
    Methods: We conducted a single-center, retrospective analysis of 180 patients who underwent FIC stent implantation between May 2017 and May 2019; 327 procedures were performed. Our primary objective was to evaluate a composite of stent thrombosis and stent restenosis. Secondary outcomes included individual predictors of in-stent restenosis (ISR) and in-stent thrombosis (IST), primary and secondary patency, access-site complications, major bleeding, pulmonary embolism, cardiovascular death, any death, intracranial bleeding, all-cause mortality, and components of major adverse cardiac and cerebrovascular events (MACCE) in a 24-month period.
    Results: A total of 327 procedures were performed for 180 patients. At 2-year follow up, 78.3% of cases remained free of any complication. Primary outcome occurred in 53 procedures (16.2%) and was highest at early (<30 days) follow-up. Primary patency at 2-year follow-up was 78.43%. There were no deaths, 1 patient (0.3%) had a subdural hematoma, and 3 patients (0.9%) had MACCE. Age and post-thrombotic syndrome (PTS) were significant predictors of primary outcome. PTS and Venous Clinical Severity score (VCSS) ≥10 were found to have higher rates of thrombosis. Active smokers, the elderly, history of deep vein thrombosis (DVT), and VCSS ≥10 had a statistically significant elevated risk of ISR.
    Conclusion: Endovascular treatment with stent implantation for non-thrombotic iliac vein lesion and PTS is safe, with low morbidity, zero mortality, low complications, and persistent improvement of symptoms. Age and PTS were significant predictors of primary outcome.

    Abstract Aim: To determine whether there is an increased risk of gastric adenocarcinoma associated with vitamin D deficiency (VDd).
    Methods: A retrospective case control study was performed of all patients diagnosed with gastric adenocarcinoma between 2005 and 2015. After we excluded the patients without a documented vitamin D level, 49 patients were included in our study.
    Results: The average age of patients with gastric adenocarcinoma and documented vitamin D level was 64 years old (95%CI: 27-86) and average vitamin D level was 20.8 mg/dL (95%CI: 4-44). Compared to a matched control group, the prevalence of VDd/insufficiency in patients with gastric adenocarcinoma was significantly higher than normal vitamin D levels (83.7% vs 16.3%). Forty-one patients (83.7%) with adenocarcinoma showed VDd/insufficiency compared to 18 (37%) patients with normal vitamin D level without gastric cancer (OR: 8.8, 95%CI: 5-22, P value < 0.0001). The average age of males with gastric adenocarcinoma diagnosis was 60 years old vs 68 years old for females (P = 0.01). Stage II gastric adenocarcinoma was the most prevalent in our study (37%).
    Conclusion: We reported a positive relationship between VDd and gastric adenocarcinoma, that is to say, patients with decreased VDd levels have an increased propensity for gastric adenocarcinoma.

    Abstract Background: Echocardiography has been a popular modality used to aid in the diagnosis of infective endocarditis (IE) with the modified Duke criteria. We evaluated the necessity between the uses of either a transthoracic echocardiography (TTE) or transesophageal echocardiography (TEE) in patients with a body mass index (BMI) greater than or equal to 25 kg/m(2) and less than 25 kg/m(2).
    Methods: A single-centered, retrospective study of 198 patients between 2005 and 2012 diagnosed with IE based on modified Duke criteria. Patients, required to be above age 18, had undergone an echocardiogram study and had blood cultures to be included in the study.
    Results: Among 198 patients, two echocardiographic groups were evaluated as 158 patients obtained a TTE, 143 obtained a TEE, and 103 overlapped with TEE and TTE. Out of these patients, 167 patients were included in the study as 109 (65%) were discovered to have native valve vegetations on TEE and 58 (35%) with TTE. TTE findings were compared with TEE results for true negatives and positives to isolate valvular vegetations. Overall sensitivity of TTE was calculated to be 67% with a specificity of 93%. Patients were further divided into two groups with the first group having a BMI ≥25 kg/m(2) and the subsequent group with a BMI <25 kg/m(2). Patients with a BMI ≥25 kg/m(2) who underwent a TTE study had a sensitivity and specificity of 54 and 92%, respectively. On the contrary, patients with a BMI < 25 kg/m(2) had a TTE sensitivity and specificity of 78 and 95%, respectively.
    Conclusions: Patients with a BMI <25 kg/m(2) and a negative TTE should refrain from further diagnostic studies, with TEE strong clinical judgment is warranted. Patients with a BMI ≥ 25 kg/m(2) may proceed directly to TEE as the initial study, possibly avoiding an additional study with a TTE.

    Abstract Objective: In this study, we assessed the risk factor profile in premature coronary artery disease (CAD) and acute coronary syndrome for adults ≤40 years old.
    Methods: A retrospective chart analysis of 397 patients ≤40 years old admitted from 2005 to 2014 for chest pain and who underwent coronary arteriography.
    Results: Of 397 patients that had undergone coronary arteriography, 54% had CAD while 46% had normal coronary arteries. When compared with patients with normal coronary arteries, patients with CAD were more likely to smoke tobacco, have dyslipidemia, be diabetic, have BMI >30 kg/m(2), have a family history of premature CAD and be male in gender.
    Conclusion: Healthcare intervention in the general population through screening, counseling and education regarding the risk factors is warranted to reduce premature CAD.
