A Case Of Occlusive Myocardial Infarction Caused By Nephrotic Syndrome In A 26-Year-Old Type 1 Diabetic, Kyle Admire, Charlotta Jornlid, Chelsea Ryan, Rebecca Pauly

Marshall Journal of Medicine

Nephrotic syndrome is a rare condition distinguished by proteinuria exceeding 3g per day. Other associated characteristics include hematuria, hypoalbuminemia, edema, and hyperlipidemia. There is an array of complications of this syndrome, which are primarily due to the profound losses of protein in the urine. One such complication is thromboembolism, with most documented cases in the form of venous thromboembolism of the extremities which is in part due to urinary loss of antithrombin III and increased synthesis of prothrombotic factors. There are limited available data regarding arterial thrombi and especially few reports about coronary thromboses, which can be life-threatening. In this …


Management Of Cryptogenic Stroke Secondary To Large Asd With Percutaneous Occluder Device And Antiplatelet Drugs, Riya Gupta, Naveed Iqbal Jan 2024

Management Of Cryptogenic Stroke Secondary To Large Asd With Percutaneous Occluder Device And Antiplatelet Drugs, Riya Gupta, Naveed Iqbal

Marshall Journal of Medicine

Atrial septal defects (ASD) represent the most common congenital heart disease diagnosed in adult population and can present with variable clinical findings. Recent literature emphasizes the importance of management of ASD especially if it is associated with structural right heart changes such as RV dysfunction, right ventricular enlargement, arrythmias or paradoxical embolism.

The decision between medical therapy versus surgical closure of ASD is a common clinical conundrum especially in the setting of cryptogenic stroke.


Management Of Asymptomatic Hypertension In The Inpatient Setting., Charles Meadows, Mehiar Elhamdani, Dial Larry, Murad Kheetan, Khaled Al-Baqain Jul 2023

Management Of Asymptomatic Hypertension In The Inpatient Setting., Charles Meadows, Mehiar Elhamdani, Dial Larry, Murad Kheetan, Khaled Al-Baqain

Marshall Journal of Medicine

Hypertension is common in hospitalized patients and is most often asymptomatic. While there are no guidelines for management of such patients, aggressive blood pressure treatment, including the use of intravenous antihypertensives, is often undertaken. While evidence of benefit is lacking, emerging data suggest that treatment of asymptomatic hypertension in the inpatient setting is associated with adverse outcomes, including acute kidney injury and ischemic stroke. In addition, the intensification of a preexisting antihypertensive regimen at hospital discharge significantly increases the risk of readmission without significant improvement in outpatient hypertension control. Such a combination of a common problem with the demonstrable benefit …

Male Breast Enlargement After Automated Implantable Cardioverter-Defibrillator Placement, Anisha Valluri, Lynne J. Goebel

Marshall Journal of Medicine

Placement of implantable cardioverter-defibrillators (ICDs) are increasing in frequency due to their indication for the prevention of sudden cardiac death in patients prone to life-threatening arrhythmias. Primary care physicians should be aware of the possible complications so they can treat their patients appropriately. This article describes a rare case of chronic unilateral breast enlargement after the placement of an ICD in a male patient with Tetralogy of Fallot.

Trans-Radial Coronary Intervention (Tci) Using 5-Fr Versus 6-Fr Guiding Catheters In The Setting Of Acute Coronary Syndrome (Acs)., Ahmed Amro, Mohammad Amro, Amal Sobeih, Obadah Aqtash, Hisham Hirzallah, Majd Kanbour, Adee El-Hamdani, Alaa Gabi, Yazan Numan, Mark Studeny, Mehiar El-Hamdani

Marshall Journal of Medicine

Background:

As in any vascular access the size of guiding catheter is an operator preference. Although multiple studies showed the use of 5-Fr versus 6-Fr guiding catheters for Transradial coronary intervention (TCI) have similar vascular safety profile and can be performed safely and successfully with both of them, the data comparing the 5-Fr vs 6-Fr guiding catheters for TCI in terms of fluoroscopy time, procedure time and contrast amount in the setting of ACS is limited. We conducted this study to compare the use of 5-Fr versus 6-Fr guiding catheters for TCI in the settings of ACS.

Method:

Percutaneous Transluminal Balloon Venoplasty: A Less Invasive Technique For Implantation Of Cardiac Leads In Patients With Limited Venous Access To The Heart, Waiel Abusnina, Zachary O. Curtis, Emilia C. Leigh, Eric Y. Auyoung, Dr. Mehiar El-Hamdani, Esam Baryun

Marshall Journal of Medicine

Since its inception, cardiac pacing has made a significant advancement in cardiology. As new therapies and devices emerge, the number of implantations is steadily increasing which requires up-to-date clinical guidelines for management. Although advanced, these mechanical devices often require maintenance and revisions to achieve optimal performance. One of the most common deteriorations is the lead failure.

In the case of lead failure requiring revision, new lead implant, or upgrading to a more advanced pacing system, venous stenosis resulting in partial or complete obstruction of the vessel can pose a real problem. This case series report introduces the technique of percutaneous …

Urgent Coronary Artery Bypass Grafting Due To Multi- Vessel Coronary Aneurysm, Obadah Aqtash, Ahmed Amro, Bilal Alam, Amal Sobeih, Melissa Lester, Rameez Sayyed

Marshall Journal of Medicine

Coronary Artery Aneurysm (CAA) is defined as a dilation of more than 1.5 times normal in a segment of the coronary artery. While the incidence of CAA is highest in the Right Coronary Artery (RCA), it is agreed that left main coronary artery or three-vessel involvement is extremely rare. Wide ranges of factors have been implicated in the cause of CAA with atherosclerosis being the most common at 50%. Congenital CAA occurs in 20-30% of cases followed by connective tissue disease at 10%. Blood stagnation and exposure of the underlying collagen make aneurysms prone to thrombosis, dissection, and vasospasm. Depending …

Going Beyond The Final Impression With Radiologic Data In The Era Of Clerical Medicine: A Case Report Of Coronary Artery Disease Found Incidentally On Computed Tomography, Andrea M. Lauffer

Marshall Journal of Medicine

Introduction:

Given the challenges in modern healthcare, physicians find themselves devoting a great deal of mental and emotional energy into executing the appropriate care for patients as well as performing their daily clerical duties. Many clinicians have resorted to innovative ways to minimize their tasks which often leads to narrowing the focus of a patient’s overall care and the birth of medical errors described in the Swiss cheese effect model.

Case Description:

A 66 year old male established care with a new primary care physician. Previous radiologic data revealed a pulmonary nodule that did not have appropriate follow up imaging. …

A Rare Case Of Asystole During A Laparoscopic Appendectomy In A Young Patient, Rachit Gupta, George Yousef, Melissa Lester

Marshall Journal of Medicine

Laparoscopic surgery has become the mainstay of treatment for uncomplicated appendicitis cases. We describe a case of a 29 year old male with a pertinent past medical history of poorly controlled hypertension who was undergoing a routine laparoscopic appendectomy for confirmed appendicitis and developed bradycardia and subsequent asystolic cardiac arrest approximately one hour into the operation. Urgent cardiopulmonary resuscitation and intravenous (IV) atropine were required to reinitiate sinus cardiac rhythm. While the patient was admitted to the intensive care unit for close monitoring following his operation, he ultimately had an uncomplicated postoperative period and an unremarkable cardiac work up and …

Inferior Stemi Complicated By Retroperitoneal Hemorrhage Due To Ruptured Aaa, Farley B. Neasman Iii, Melissa D. Lester, Nepal C. Chowdhury

Marshall Journal of Medicine

When patients present with life threatening conditions, a rapid cost-benefit analysis prioritizes care and commits treatment to a certain course that, in the case of ST Elevation Myocardial Infarction (STEMI) treated with drug-eluting stents (DES), could be fatal if there is any deviation. Antiplatelet therapy is vital and secondary concerns (i.e. bleeding diatheses) may accept suboptimal outcomes – in rare cases, another life-threatening condition may be unmasked, the treatment for which runs directly counter to the first. We present a case of STEMI with high clot burden treated with multiple DES, complicated by retroperitoneal hemorrhage due to a ruptured abdominal …

Marshall Journal of Medicine

Peripheral Vascular Disease (PVD) is a rapidly growing and recognized disease of the peripheral circulation. Its presentation can vary between asymptomatic state, exercise limiting limb pain, limb loss and even death. Advances have been achieved in the treatment of PVD specially in the field of interventional cardiovascular medicine. Different devices and techniques are used in the treatment of peripheral atherosclerotic disease, which has lowered the need for bypass surgery. Although invasive peripheral intervention has a low rate of complications, there are still well recognized acute and chronic complications that an operator should be aware of. We present an interesting case …

Retrograde Pedal Access For Revascularization Of Infrapopliteal Arterial Occlusive Disease In Critical Limb Ischemia (Cli) Patients As A Primary Approach., Ahmed Amro, Alaa Gabi, Shahed Elhamdani, Haytham Aljoudi, Mehiar El-Hamdani

Marshall Journal of Medicine

Introduction:

We are presenting three cases (out of similar several cases) where tibio-pedal approach was performed as an initial primary approach for limb salvage in patients with CLI secondary to Infra-popliteal (IP) disease. We consider this approach to be a necessary evolution in endovascular intervention.

Discussion:

Retrograde pedal access is safe, feasible with high technical success rate and a relatively low procedural complication rate, with low 30 days mortality and low rate of major adverse cardiac events. Freedom from major adverse limb events and limb salvage are both high at 1 year follow up. It allows quick therapy and short …

Endovascular Therapy Of Tasc-D Lesion In Critical Limb Ischemia, Ahmed Amro, Md, Alaa Gabi, Md, Dr. Mehiar El-Hamdani, Md, Facc, Fscai

Marshall Journal of Medicine

CLI (Rutherford class IV-VI) is a terminal stage of peripheral artery disease (PAD); it is defined by the presence of resting pain and/or tissue loss for at least two weeks that may require urgent revascularization to promote healing and prevent limb loss.For patients with infrarenal aortoiliac occlusive disease, the revascularization options are surgery like aortofemoral bypass and axillofemoral bypass or percutaneous intervention. Aortoiliac and aortofemoral bypass procedures are associated with 74% to 95% 5-year patency rates, respectively, which are comparable but not superior to percutaneous therapies.These operations may imply a significant morbidity and mortality on CLI patients who usually have …


Chronic Kidney Disease And Acute Myocardial Infarction: The Story After 1 Year, Paulette S. Wehner, William A. Nitardy May 2016

Chronic Kidney Disease And Acute Myocardial Infarction: The Story After 1 Year, Paulette S. Wehner, William A. Nitardy

Internal Medicine

When chronic kidney disease (CKD) is part of the clinical history for a patient with acute myocardial infarction, the interventional cardiologist experiences an increased anxiety level. An acute myocardial infarction with renal disease requires more attention to dye load and fluid status, and general opinion exists regarding the negative outcomes of these “sicker” patients.

Mark Navarro and colleagues completed a thorough study from a different angle. We know the interventionalists’ concerns are justified acutely as these CKD patients have a higher level of inpatient complications, but these authors chose to look at the patients 1 year from their event to …

An Unusual Migration Of A Stent: A Case Report, Fikadu G. Tekleyes Md, Melissa D. Lester Md, Mark A. Studeny Md, Ellen A. Thompson Md, Steven Craig Md

Marshall Journal of Medicine

Stent dislodgment and embolization is a rare complication of coronary stenting.

There are reports of intra-coronary stent entrapment, stripping, and dislodgement

during percutaneous coronary interventions causing potentially life threatening

complications, including intra-coronary or systemic embolization. Reports of

dislodgment and migration of previously placed drug eluting intra-coronary stent

several months after deployment are very limited in the literature. We describe a

drug eluting stent dislodgment and migration in an 88 year-old male 10 months after

its deployment.

Rising health care costs have employers searching for remedies to the increasing rates they pay for employee health insurance. The development of U.S. health insurance policies, with the option of utilizing medical tourism as a low cost care provider for treatment of cardiac coronary bypass surgery provides a method for receiving treatment. The medical tourism approach to providing treatment for bypass surgery has prompted hospitals in India, Thailand, and Singapore to seek U.S. patients. A comparison of costs for bypass treatment between the U.S. and these countries illustrates some of the issues and concerns that arise when making such comparisons. …


Cancer Cachexia And Cardiac Atrophy In The Apcmin/+ Mice Model Of Colon Cancer, Nandini Durga Prasanna Kumar Manne Jan 2011

Cancer Cachexia And Cardiac Atrophy In The Apcmin/+ Mice Model Of Colon Cancer, Nandini Durga Prasanna Kumar Manne

Theses, Dissertations and Capstones

Cancer cachexia is a muscle wasting condition that occurs in response to a malignant growth in the body. Cachexia is associated with heart failure and is estimated to be the immediate cause of death in about a third of all cancer patients. The purpose of this study was to investigate cardiac atrophy in the APCmin/+ mouse model of colorectal cancer. Compared to age matched C57BL/6 (BL6) mice, APCmin/+ body mass and heart mass were lower at 12 (11.1 Ѡ4.5% and 7.6 Ѡ2.8%, respectively) and 20-weeks (26.1 Ѡ2.5% and 6.0 Ѡ3.8%, respectively) of age (P < 0.05). Immunoblot analysis revealed that these changes in mass were accompanied by increased activation of protein kinase B (Akt Thr 473: 74.4 Ѡ10.9% and 216.0 Ѡ19.6% ; Akt Ser 308: 161.6 Ѡ31.7% and 367.4 Ѡ41.6% at 12- and 20-weeks, respectively, (P < 0.05)), mammalian target of rapamycin (mTOR Ser2448: 23.2 Ѡ13.2% and 44.0 Ѡ16.4% at 12- and 20-weeks, respectively, (P < 0.05)), 5' adenosine monophosphate-activated protein kinase (AMPK: 19.6 Ѡ5.2% and 22.5 Ѡ5.5% at 12- and 20-weeks, respectively, (P < 0.05)) and elevated levels of the autophagy regulator beclin1 (4.7 Ѡ3.3% and 9.5 Ѡ3.0% at 12- and 20-weeks, respectively, (P < 0.05)). No evidence of increased cardiac apoptosis, protein ubiquitination or activation of cardiac caspases or calpains was noted. Taken together, these data suggest that the cardiac atrophy that occurs in the 12- and 20-week old APCmin/+ mouse is relatively modest compared to that seen with other tumor models [1] and is associated with evidence of increased cardiac autophagy.

Diversion Of The Inferior Vena Cava Following Repair Of Atrial Septal Defect Causing Hypoxemia, Ellen A. Thompson, Silvestre Cansino, Dennis Moritz, Romaine Perdue Perdue

Internal Medicine

Atrial septal defects (ASDs) are a common congenital abnormality, and operative repair is a routine, safe procedure. Diversion of the inferior vena cava (IVC) into the left atrium is an unusual complication following ASD closure. We report a case that illustrates the problem created by this right-to-left shunt. A middle-aged woman underwent ASD repair. She developed hypoxemia postoperatively. A transthoracic echocardiogram confirmed a right-to-left shunt, found only with agitated saline injected into the femoral vein, not into the basilic vein. Surgical reexploration revealed a residual ASD diverting IVC flow into the left atrium, which was repaired with a pericardial patch. …
