INTRODUCTION: The usefulness of carbon dioxide (CO2 ) gas digital subtraction angiography (DSA) has been reported for patients with renal insufficiency and allergy to iodinated contrast agents. However, CO2 gas cannot replace the iodinated contrast agent in all cases owing to some disadvantages. We describe balloon-occluded CO2 DSA (B-CO2 DSA) as an improved CO2 DSA procedure for interventions in the internal iliac artery (IIA) region and compare the quality of images obtained using conventional CO2 DSA and B-CO2 DSA...

This study aimed to evaluate the use of the HeartMate percutaneous heart pump, a catheter-based axial flow pump designed to provide partial left ventricular support, in patients who underwent high-risk percutaneous coronary intervention (PCI). Patients who are hemodynamically unstable, or at risk of being hemodynamically unstable, while undergoing PCI may require mechanical circulatory support. Fifty high-risk patients were enrolled in a prospective, nonrandomized, multicenter, open-label trial. Primary end points were freedom from hemodynamic compromise during PCI and a composite measure of major adverse events...

Introduction: Ultrafast tracking of anesthesia (UFTA) is practiced routinely, whereas immediate on-table extubation after off-pump coronary artery bypass (OPCAB) grafting surgery has many concerns. The purpose of our study was to evaluate the safety and feasibility of immediate extubation (IE) versus UFTA. Methods: Sixty patients were enrolled who underwent OPCAB surgery. The two groups IE and UFTA had thirty patients each. Inclusion criteria were patients for OPCAB surgery including left main stenosis...

During the past decade transcatheter aortic valve implantation (TAVI) has revolutionized our approach to heart valve disease. Although largely applied to patients with calcific aortic valve stenosis, there is an unmet clinical need to also treat patients with aortic valve insufficiency in patients with non-calcific aortic valve disorders. The following Techno-College tutorial demonstrates our pre-clinical experience with a novel non-occlusive, self-homing TAVI system, developed with Strait Access Technologies, that we hope will improve outcomes for treatment of non-calcific aortic valve insufficiency...

A 76-year-old woman, who had a history of ocular sarcoidosis, was incidentally found to have a huge pulmonary artery aneurysm, along with aortic, mitral and tricuspid valve insufficiency. She underwent pulmonary artery plication along with surgeries for 3 valves. A specimen of the slightly enlarged ascending aorta revealed the involvement of sarcoidosis in the aortic wall. The systemic granulomatous inflammation process of sarcoidosis possibly affected the valvular and vascular pathology. Herein, we report a rare case of aortic sarcoidosis complicated by a pulmonary artery aneurysm...

MYOCARDIAL INFARCTION IN THE OLD PATIENT: Even old patients may crucially benefit from reopening the occluded coronary artery by percutaneous coronary intervention with stent implantation. Bleeding complications can be reduced by choosing the radial instead of the femoral vascular approach for cardiac catheterization. STATINS FOR THE ELDERLY: WHEN TO START UND WHEN TO STOP?: Elderly benefit no less than the younger from statins. "Goal-oriented statin therapy" is preferable to the "statin strategy of fixed dose"...

BACKGROUND: Eccentric valve deployment after transcatheter aortic valve replacement (TAVR) has been associated with abnormal leaflet shear stresses that may accelerate structural valve deterioration (SVD). This phenomenon has not been studied in patients receiving Sapien 3 prostheses (Edwards Lifesciences). METHODS: A retrospective cohort analysis of 100 patients who received Sapien 3 valves between 2013 and 2015 at a single institution was performed. Axial fluoroscopic images from the co-planar view were used to assess TAVR asymmetry, which was defined as a ratio of left-to-right valve heights ≤0...

Left ventricle (LV) assist, which refers to the use of a mini-pump or catheter implanted across the aortic valve connected to the pump, can promote myocardial recovery after left ventricle failure. However, conventional LV assist catheters compress the aortic valve, which can induce aortic insufficiency. Here we describe a novel LV assist catheter containing a retractable stent at its distal end that may prevent such insufficiency. The device was tested in six goats in which the coronary artery was ligated to induce acute LV failure, and then an LV assist was installed with a novel catheter in the left ventricle via the left subclavian artery...

Severe sepsis is critical to health and can result in acute renal failure (ARF). Tissue factor (TF) and thrombomodulin (TM) play key roles in vascular endothelial functions by helping maintain microcirculation in the kidney. Budding uninhibited by benzimidazole-1 (Bub1) plays a role in Akt and JNK signaling, which control TF and TM, respectively. We hypothesized that Bub1 could control vascular endothelial function in sepsis. The aim of this study was to determine the role of Bub1 in septic ARF. We used Mouse cecum ligation and puncture (CLP) using low Bub1 expressing (Bub1) and wild-type (Bub1) mice in vivo and lipopolysaccharide (LPS) stimulation of human aortic endothelial cell (HAEC) in vitro...

We report the first successful valve-in-valve (ViV) implantation into a failed Edwards Biophysio surgical prosthesis (Edwards Lifesciences, Irvine, CA) and also the first use of the J-Valve system (Jie Cheng Medical Technologies, Suzhou, China) in a ViV configuration. A 77-year old male had symptomatic severe aortic stenosis secondary to failure of a 25 mm Biophysio bioprosthetic valve implanted 11 years previously, along with concomitant coronary artery bypass grafting. Transthoracic echocardiography (TTE) revealed calcified leaflets, a mean aortic gradient of 50 mm Hg, and an estimated valve area of 0...

OBJECTIVES: The aortic arch repair in the neonatal period is a complex procedure with significant morbidity. We define a useful double-perfusion technique and its effect on the function of abdominal organs in the postoperative course. METHODS: Nine patients with double perfusion (Group 1) were compared with 14 patients with antegrade cerebral perfusion (Group 2). The objective was to discern the incidence of postoperative acute kidney injury and impaired hepatic function, as well as tissue perfusion and myocardial function parameters...

BACKGROUND: Cardiovascular disease accounts for 35% to 50% of the causes of mortality in chronic kidney disease. The majority of patients in substitution therapy in Mexico are subdialyzed owing to limited economic resources. This produces more cardiac deterioration than described in the statistics and has a direct impact on the prognosis of kidney transplantation. The aim of this work was to demonstrate and to quantify the improvement in the echocardiographic parameters 6 months after renal transplantation in patients with stable renal function...

OBJECTIVES: The aim was to evaluate the impact of a bicuspid aortic valve (BAV) on local shear stress and on the pressure profile on the elements of the aortic root (AoR). METHODS: The experiment setup included a BAV with aortic valve stenosis (n = 5 pigs, 67 ± 3.5 kg) and insufficiency (n = 5 pigs, 66.7 ± 4.4 kg). By implanting 6 high-fidelity microsonometric crystals in each AoR, we determined the 3-dimensional (3D) geometry of the AoR. Experimental and geometric data were used to create a 3D time- and pressure-dependent computed fluid dynamic model of the AoR with the BAV...

We describe a case of Type A aortic dissection in a 25 year old lady who had undergone a Ross Procedure for aortic valve endocarditis 13 years previously. She was pregnant and noted to have significant enlargement of the aortic root during the latter portion of the third trimester of her pregnancy. An echocardiogram performed after delivery demonstrated new aortic valve insufficiency in addition to an aortic root diameter of 6.5 cm. A CT angiogram demonstrated a Type A aortic dissection involving only the very proximal portion of the ascending aorta...

The gold standard of care for coronary artery disease, a leading cause of death for in the world, is balloon angioplasty in conjunction with stent deployment. However, implantation injuries and long-term presence of foreign material often promotes significant luminal tissue growth, leading to a narrowing of the artery and severely restricted blood flow. A promising method to mitigate this process is the use of biodegradable metallic stents, but thus far they have either degraded too slowly (iron) or disappeared prematurely (magnesium)...

OBJECTIVE: It is not clear whether endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms (AAAs) results in an increase in renal insufficiency during the long term compared with open repair (OR). We reviewed our experience with AAA repair to determine whether there was a significant difference in postoperative and long-term renal outcomes between OR and EVAR. METHODS: A retrospective cohort study was conducted of all patients who underwent AAA repair between January 1993 and July 2013 at a tertiary referral hospital...

Aims: The metabolism of the failing heart is characterized by an increase in glucose uptake with reduced fatty acid (FA) oxidation. We previously found that the genetic deletion of fatty acid binding protein-4 and -5 (DKO) induces an increased myocardial reliance on glucose with decreased FA uptake in mice. However, whether this fuel switch confers functional benefit during the hypertrophic response remains open to debate. To address this question, we investigated the contractile function and metabolic profile of DKO hearts subjected to pressure overload...
