Comparison Between Two Protocols For Deflation Of The Tr Band Following Coronary Procedures Via The Radial Route, Hassan Al Riyami, Adil Al Riyami, Sunil K. Nadar

Journal of the Saudi Heart Association

Aim: Coronary interventions are increasingly being performed via the radial rather than femoral route because of the lower complication rate. Compression devices such as the TR band are used to achieve hemostasis after the procedure. At present, there are no clear protocols for the deflation of the band. In this study we compared two protocols (early deflation with increased intervals vs. late deflation with smaller intervals) in terms of total time to band removal and complications, and patient and staff satisfaction. Methods: All patients who underwent a transradial coronary procedure and had a TR band fitted were enrolled into the …

The Use Of Antidepressants In Patients With Heart Failure, Norah Alsumih, Rahaf Alqahtani, Faisal Almutairi, Rakan Faraj, Turki Alsubeai, Ahmed Alghanim, Shmylan Alharbi, Hind Almodaimegh

Journal of the Saudi Heart Association

Background: Heart failure (HF) is a chronic disease affecting patients’ quality of life (QoL) and may cause depression. Recent studies reported that the prevalence of depression in patients with HF is 21.5%. Antidepressants, mainly selective serotonin reuptake inhibitors, are usually prescribed for HF patients diagnosed with depression. Some evidence supports antidepressant’s role in improving symptoms by enhancing the psychological aspect of their QoL. Depression screening and treatment are important in the multidisciplinary management; however, their survival benefits are inconsistent. In our study, we aim to investigate the prevalence of depression and the use of antidepressants in patients with HF as …

An Observational Comparison Of Distal Radial And Traditional Radial Approaches For Coronary Angiography, Anupam Bhambhani, Salil Pandey, Aditi N. Nadamani, Kartikey Tyagi

Journal of the Saudi Heart Association

Background: Several studies have recently reported regarding feasibility and safety of distal transradial access (d-TRA) in the anatomical snuff-box (ASB); however, literature comparing it with the conventional TRA at the wrist (w-TRA) is sparse. This study compares the technical efficiency and safety of ASB and wrist approaches for TRA for coronary angiography (CAG) and evaluates the radial artery (RA) anatomy at these sites. Methods: Two hundred consecutive patients undergoing CAG via w-TRA or d-TRA (100 in each group) were investigated. The primary endpoint was comparison of procedural efficiency of the two methods, defined as CAG completion from the intended access …

Occurence Of Left Main Occlusion On Tuesday: Chronobiology Of Acute Myocardial Infarction, Gianluca Rigatelli, Marco Zuin

Journal of the Saudi Heart Association

Objectives: The existence of a “weekend effect” for onset of acute myocardial infarction (AMI) has been suggested in the past, but the relation with the culprit vessel has not been investigated. MI due to left main coronary artery lesion represents a particularly serious life-threatening condition. Our study was aimed to assess the chronobiology of admission to the emergency department for AMI considered to be induced by a left main culprit lesion. Methods: We retrospectively reviewed patients who experienced an AMI due to a left main culprit lesion between January 1, 2008 and January 1, 2018 stratifying them according to the …

A Real-Life Correlation Between Clinical Syntax Score Ii And Carotid Intima-Media Thickness In Patients With Stable Coronary Artery Disease, Mahmoud Abdelnabi, Abdallah Almaghraby, Ozge O. Tok, Tugba K. Oz, Yehia Saleh, Ahmed Morsi, Hiatham Badran

Journal of the Saudi Heart Association

Background: SYNTAX score II (SSII) is an update of the established SYNTAX score (SS) that uses clinical variables such as age, sex, creatinine clearance, left ventricular ejection fraction, chronic obstructive pulmonary disease, and peripheral arterial disease. Furthermore, SSII has been proven to be a more powerful predictive tool than SS in patients with complex coronary artery disease (CAD). Carotid õntima-media thickness (CIMT) is a widely used noninvasive evidence for subclinical or early atherosclerosis, and it was proved to be an independent predictor for cardiovascular events. Most of the previously published articles studied the association between the CIMT with old cardiovascular …

Methods: All patients eligible for TAVR between June and August of 2019 were invited to participate in a pilot project using peer support and use of shared decision-making (SDM) aids. Former TAVR patients were trained to be Mended Hearts TAVR peer volunteers. Participants were connected by telephone …

Giant Left Main Coronary Artery Aneurysm Presenting As Multiple Implantable Cardioverter Defibrillator Shocks, Yury Malyshev, Asma Syed, Ricardo Castillo, Rumman A Syed, Sonu Sahni

Touro College of Osteopathic Medicine (New York) Publications and Research

Giant aneurysms of the left main coronary artery are one of the rarest findings in cardiology, encountered in less than 0.02% of patients. The presentation is usually the same as coronary artery disease since most coronary aneurysms in the western world are associated with atherosclerosis. Here we report the first case of giant aneurysm of the left main coronary artery presenting as ventricular tachycardia with multiple shocks of the defibrillator in a 57-year-old man with heart failure. We also review the etiology, pathology, and management of coronary aneurysms.

How Rare Is Isolated Rheumatic Tricuspid Valve Disease?, Edme R. Mustafa, Octavian Istrătoaie, Roxana Mandia, Georgică C. Târtea, Cristina Florescu

Journal of Mind and Medical Sciences

The incidence of rheumatic fever (RF) has markedly decreased in Europe since the beginning of the 20th century due to improved living conditions, early antibiotic therapy in streptococcal pharyngitis, and changes in serotypes of circulating streptococci. Isolated outbreaks of RF are still found in various parts of the world and the disease has changed its presentation with milder joint symptoms and subclinical carditis that make the correct diagnosis more difficult. Patients can present many years later with severe valve disease and significant disability. This article presents a case of isolated rheumatic tricuspid valve disease that presented with signs and symptoms …

The Texas Heart Institute Journal

We evaluated aortic tissue specimens from patients undergoing tetralogy of Fallot repair, to determine whether histologic abnormalities affect postsurgical aortic remodeling and other patient-related variables.

Using light microscopy, we studied full-thickness aortic wall tissue operatively excised from 118 consecutive patients undergoing intracardiac repair of tetralogy of Fallot. We performed multiple linear regression analysis to identify independent predictors of change in aortic root dimensions, which we measured with echocardiography after repair and every 3 months thereafter.

Thirty histologically normal specimens were used as controls. Elastic fiber fragmentation was found in 74.6% of the abnormal specimens, mucoid extracellular matrix accumulation in 49.2%, …

Modified Danielson Technique For Prosthetic Aortic Valve Endocarditis And Aortoventricular Discontinuity, Gianfranco Filippone, Claudia Calia, Mario Finazzo, Fabio Fazzari, Giovanni Caruana, Vincenzo Argano

The Texas Heart Institute Journal

Endocarditis is a devastating complication of prosthetic aortic valve replacement. The infective process can destroy aortic annulus tissue, making conventional surgical valve replacement difficult or impossible and causing aortoventricular discontinuity. Several treatment techniques have been proposed. One of these, the Danielson technique, involves translocating the aortic valve to the native ascending aorta, débriding the abscess cavity, closing the coronary ostia, and bypassing the coronary arteries with a Y anastomosis between 2 vein grafts. We describe our use of a modified Danielson technique in a 68-year-old man with advanced prosthetic valve endocarditis that was associated with aortic annulus destruction and aortoventricular …

Speckle-Tracking Echocardiography In Cardio-Oncology And Beyond, Raymundo A Quintana, Linh P Bui, Rohit Moudgil, Nicolas Palaskas, Saamir Hassan, Jun-Ichi Abe, Elie Mouhayar, Syed Wamique Yusuf, Antonieta Hernandez, Jose Banchs

The Texas Heart Institute Journal

Speckle-tracking echocardiography has enabled clinicians to detect changes in myocardial function with more sensitivity than that afforded by traditional diastolic and systolic functional measurements, including left ventricular ejection fraction. Speckle-tracking echocardiography enables evaluation of myocardial strain in terms of strain (percent change in length of a myocardial segment relative to its length at baseline) and strain rate (strain per unit of time). Both measurements have potential for use in diagnosing and monitoring the cardiovascular side effects of cancer therapy. Regional and global strain measurements can independently predict outcomes not only in patients who experience cardiovascular complications of cancer and cancer …

Robotic-Assisted Percutaneous Coronary Intervention Through Transradial Approach: Experience In 4 Patients With Complex Lesions, Amornpol Anuwatworn, Muhammad Ali Kahn, Tomasz Stys, Marian Petrasko, Adam Stys

The Texas Heart Institute Journal

Robotic-assisted percutaneous coronary intervention can reduce the exposure of interventional cardiologists to radiation and minimize the risk of occupational orthopedic injuries from wearing heavy protective aprons. The PRECISE (Percutaneous Robotically-Enhanced Coronary Intervention) study showed the efficacy and safety of robotic-assisted procedures for relatively low-risk lesions in single coronary arteries. Several reports have described robotic-assisted treatment of complex high-risk lesions, mostly through the transfemoral approach. We report 4 cases of patients in whom we used the transradial approach to treat complex lesions in the left anterior descending coronary artery with bifurcation balloon angioplasty reconstruction (2 cases), in the ostium of the …

Articles, Abstracts, and Reports

Background

Despite guidelines supporting FFR/iFR to guide PCI, these modalities remain underutilized. We sought to characterize factors associated with FFR/iFR use in patients undergoing index PCI for an acute coronary syndrome (ACS) or stable ischemic heart disease (SIHD).

Methods

ICD-9/10 codes were used to identify patients undergoing PCI and receiving FFR/iFR for an ACS (n=1,042,896) or SIHD (n=255,213) in a Medicare claims database from Jan. 1, 2013-June 30, 2018. Patients with functional/anatomical testing were excluded (5d prior in ACS; 60d prior in SIHD). Individuals with FFR/iFR performed 1-60 days prior to PCI were also excluded to limit analysis to non-staged …

Articles, Abstracts, and Reports

Background

The 2018 AHA/ACC Cholesterol Guideline recommendation to classify ASCVD patients as very high-risk (VHR) vs not-VHR (NVHR) has important implications for ezetimibe and PCSK9 inhibitor eligibility. We aimed to define the clinical characteristics of these two groups within a large multi-state healthcare system in the Western U.S.

Methods

We performed a retrospective cohort analysis of patients defined as having ASCVD in 2018 using EHR ICD-10 codes. VHR was defined by ≥2 major ASCVD events (ACS ≤12 months, history of MI >12 months, ischemic stroke, or symptomatic PAD) or 1 major ASCVD event and ≥2 high-risk conditions (age ≥65, DM, …

Comparison Of Echocardiographic Outcomes Following Transcatheter Aortic Valve Replacement With Edwards S3 23 Mm Versus Medtronic Evolut 26 Mm Valves, Michael Ring, Ruyun Jin, Rollie Parrish, Brydan Curtis, Matthew Forrester, Branden Reynolds, Sameer Gafoor

Articles, Abstracts, and Reports

Background

Patients with small aortic valve annulus (SAVA) undergoing TAVR are prone to higher post TAVR trans-valve gradients. In many such patients, the choice of TAVR valve commonly involves choosing between the Edwards S3 23 mm (ES23) versus the Medtronic Evolut 26 mm (ME26). The supraannular design of the Evolut has been touted as providing superior hemodynamics in SAVA. We sought to compare performance of these two valves in SAVA, particularly in regard to occurrence of elevated trans-valve gradients.

Methods

We queried the Providence St Joseph Health STS/ACC TVT Registry database for patients undergoing TAVR for SAVA with either the …
