New onset hypertension-rare intimal variant fibromuscular dysplasia

SummaryFibromuscular dysplasia (FMD) involving the renal arteries commonly presents as hypertension secondary to renal artery stenosis. Atypical patterns involving intima are rare and contribute to less than 10% cases of FMD. We present a relatively uncommon case of new onset hypertension in a 30-year-old woman resulting from intimal variant FMD involving the left renal artery. Renal duplex ultrasonography and angiography showed stenosis of the left renal artery consistent with intimal variant FMD. Percutaneous transluminal angioplasty of the stenotic lesion was successfully performed. Following angioplasty, her blood pressure was normalized. Renovascular hypertension secondary to FMD involving intimal layer is rare and requires a high index of clinical suspicion. Renal duplex ultrasonography is the recommended initial test of screening for renal artery stenosis in appropriate patients. The standard selective renal angiography, intravascular ultrasound, along with or without hemodynamic assessment should be utilized when renovascular intervention is contemplated. Percutaneous transluminal angioplasty is the mainstay of treatment for those who meet the criteria of intervention

Left ventricular noncompaction and myocardial fibrosis: a case report

<p>Abstract</p> <p>Background</p> <p>Left ventricular noncompaction (LVNC) is a rare congenital abnormality. It is currently classified as a genetic cardiomyopathy and results from early arrest of endomyocardial morphogenesis. The pathophysiology of left ventricular dysfunction, which becomes apparent beyond the 4^thdecade of life, is unclear.</p> <p>Case report</p> <p>We report a case of 60-year-old woman who presented with shortness of breath and showed noncompacted endocardium on echocardiography. Cardiac catheterization and viral studies were unremarkable. Histology revealed endomyocardial fibrosis without disarray. She was subsequently diagnosed with LVNC and treated with medications.</p> <p>Discussion</p> <p>Cardiologists and other physicians should be aware of LVNC due to its high likelihood of misdiagnosis and associated high complication rates. Early diagnosis, intervention and screening among family members can decrease the morbidity and mortality associated with LVNC.</p

An unusual complication of polyarteritis nodosa with massive retroperitoneal hemorrhage: a case report

<p>Abstract</p> <p>Background and Case report</p> <p>Polyarteritis Nodosa (PAN) is a systemic necrotizing vasculitis that affects medium-sized and occasionally involves small arteries leading to the disruption of the internal and external elastic lamina and contribute to the development of aneurysms. Aneurysms develop at bifurcation of major blood vessels; they are prone to thrombosis, rupture and haemorrhage. Retroperitoneal haemorrhage around kidneys was previously reported in patients with PAN. We report a case of massive retroperitoneal bleeding from inferior pancreaticoduodenal artery aneurysm rupture in a 70-year-old female with PAN.</p> <p>Conclusion</p> <p>Prognosis of untreated PAN is very poor with 20% 5 year survival rate, therefore early recognition of the disease will prevent catastrophic complications and improves survival.</p

Acute chest pain: Acute coronary syndrome versus lead perforation: A case report

<p>Abstract</p> <p>Background</p> <p>Diagnosing pacemaker lead perforation in the setting of chest pain and EKG changes is difficult and usually not considered unless we have awareness and high index of suspicion. This kind of clinical scenario represents one of the diagnostic challenges.</p> <p>Case presentation</p> <p>A 77 year-old Caucasian female came to emergency room with left sided non-exertional chest pain radiating to her back for the past two days. A week prior to this presentation, she had a stent supported angioplasty for in-stent re-stenosis and subsequently dual chamber pacemaker implantation for sick sinus syndrome. On physical exam she is very obese, had normal vital signs, peripheral pulses and cardio-respiratory exam. Electrocardiogram revealed new T- wave inversions in inferior and anterior leads. Initial chest X-ray, 2D-Echocardiogram and cardiac enzymes were normal. Acute coronary syndrome was considered as an initial probable diagnosis. She was anticoagulated with heparin and eptifibatide. Patient continued to have chest pain with negative cardiac biomarkers. She developed hypotension, oliguria, elevated white count, pyuria and renal failure. Because of a normal 2D-echocardiogram, cardiac etiology for shock was not suspected. After initial fluid challenge, empiric treatment for septic shock was initiated with antibiotics and vasopressors. Work up for pulmonary embolism and intra-abdominal hemorrhage was negative. Because of persistent chest pain, shock with cold & clammy extremities and elevated central venous pressure cardiogenic shock was considered and a repeat 2D-echocardiogram was done on third day of hospitalization which revealed pericardial effusion. Non-contrast CT-scan chest done to look for lead position confirmed that she had hemorrhagic pericardial effusion along with lead perforation. Patient underwent pericardial window placement along with over-sewing of atrial wall to seal the leakage point. The patient improved and was then discharged from the hospital.</p> <p>Conclusion</p> <p>Lead perforation presenting with chest pain and EKG changes is often not appreciated resulting in significant delay in diagnosis and inappropriate treatment.</p

Left Ventricular Pseudoaneurysm Dissecting into the Anterior Chest Wall: A Rare Cause of Sudden Onset Excruciating Chest Pain

Left ventricular pseudoaneurysm (LVPA) is associated with a significant mortality rate of up to 45% in the first year after diagnosis. It is a very rare entity and hence the true incidence and natural history are not clearly known. Clinical presentation varies widely and requires a high index of suspicion for diagnosis. We report the case of a 72-year-old woman with a remote history of left ventricular aneurysm repair during coronary bypass surgery who presented to the emergency department with acute onset of left-sided chest pain and a pulsatile chest wall swelling. She was haemodynamically stable but required an intravenous morphine drip for pain control. Contrast-enhanced computed tomography of the chest showed a large LVPA dissecting through the anterior chest wall. Surgical treatment was discussed with the patient but she opted in favour of comfort care. She died 5 days later from complete rupture of the LVPA. With this report, we aim to raise the level of awareness of LVPA that could anatomically expand and rupture. Early diagnosis and timely surgical intervention is the treatment of choice

Sudden Cause of Cardiac Death—Be Aware of Me: A Case Report and Short Review on Brugada Syndrome

Introduction. Brugada syndrome accounts for about 4% of sudden cardiac deaths (SCD). It is characterized by an ST-segment elevation in the right precordial electrocardiogram (EKG) leads. Case Presentation. We describe a 39-year-old healthy Caucasian man who was admitted to the intensive care unit after being cardioverted from ventricular fibrillation (VF) arrest. His past history was significant for an episode of syncope one month prior to this presentation for which he was admitted to an outlying hospital. EKG during that admission showed ST elevations in V1 and V2 leads, a pattern similar to Type 1 Brugada. A diagnosis of Brugada syndrome was missed and the patient had a cardiac arrest a month later. We discuss a short review of Brugada syndrome and emphasize the need to look for it in patients presenting with SCD and malignant arrhythmias. Conclusion. Physicians should always consider Brugada syndrome in the differential diagnosis of ST-segment elevation in anterior precordial leads of EKG and associated VT/VF. Although more than 17 years have passed since the first case was reported, increased awareness of this syndrome is needed to identify patients with EKG changes and treat them accordingly to prevent incidence of (SCD) and its deleterious complications

Isolated Left Main Coronary Artery Stenosis after Thoracic Radiation Therapy: To Operate or Not to Operate

Radiation therapy of neoplasms involving the chest or mediastinum results in a wide spectrum of cardiac complications including coronary artery disease, which can present in patients with few or no traditional cardiac risk factors. We report a case of radiation induced coronary artery disease in a 60-year-old female with a history of stage IIIA nonsmall cell lung carcinoma which was diagnosed eight years earlier and treated with chemotherapy and radiotherapy. She presented to the hospital with atypical chest pain that had occurred intermittently over the preceding week. Her initial electrocardiogram and cardiac enzymes were within normal limits. However, following an indeterminate exercise nuclear stress test, she developed chest pain and elevated cardiac enzymes. Coronary angiography demonstrated 90% stenosis of the left main coronary artery ostium, without any evidence of atherosclerotic disease or stenosis in other coronary arteries. She underwent surgical revascularization, which revealed dense adhesions surrounding the heart. During surgery, she developed severe bleeding and died. Coronary artery disease can present within years of radiation exposure, and ostial lesions are typical. Treatment is often challenging because of the effects of radiation on other tissues and the risks of revascularization procedures. Therefore, a multidisciplinary team approach should be considered

An alien in the heart

We report a case of a 38-year-old-man who presented with altered mental status. The patient was diagnosed with infective endocarditis (IE) originating from the GORE HELEX septal occluder device, which was placed 15 months earlier for symptomatic atrial septal defect. Brain imaging revealed shower emboli phenomena from the known IE. The patient developed hydrocephalus for which external ventriculostomy was performed. Improved neurological status warranted open heart surgery. The patient was later confirmed to be an intravenous drugs abuser, prejudicing IE. This case highlights the importance of meticulously monitoring patients with suspected high-risk behavior with an implanted intracardiac prosthetic device

Gastric Sarcoidosis: A Rare Clinical Presentation

Gastrointestinal (GI) sarcoidosis is a very rare disease, which clinically presents along with systemic disease or as an isolated finding. Gastric sarcoidosis is the most common form of GI sarcoidosis. Symptomatic gastric sarcoidosis is rare and only few case reports have been described in the literature with well-documented histological evidence of noncaseating granulomas. We present an interesting case of gastric sarcoidosis in a 39-year-old Caucasian man with symptoms of epigastric pain and profound weight loss. His endoscopic gastric mucosal biopsies revealed noncaseating granulomas consistent with gastric sarcoidosis. Treatment with oral steroids alleviated his symptoms with no recurrence in 2 years. Gastric sarcoidosis should be considered in patients with history of sarcoidosis and GI symptoms

Dual coronary ‐ cameral fistula “double the trouble”

Abstract A patient presenting with worsening dyspnea and left‐sided chest pain underwent heart catheterization, found to have a rare connection between the right and left coronary arteries draining into the left ventricle, consistent with dual coronary‐cameral fistula
