RESUMEN
Systemic Lupus Erythematosus represents a chronic autoimmune disorder characterized by multiorgan involvement. Lupus myocarditis is a rare presentation of one of the cardiac complications of lupus with an incidence of 3-9%. It usually presents with non-specific symptoms such as dyspnea, orthopnea, chest pain, pedal edema, fever, diaphoresis, paroxysmal nocturnal dyspnea, nausea, vomiting, or palpitations. Even though endomyocardial biopsy is considered the gold standard diagnostic approach, other non-invasive diagnostic alternatives including cardiac magnetic resonance (CMR) have been studied. Therapeutic interventions may range from high-dose steroids, and IVIG, to the most advanced strategies such as mechanical circulatory support including VenoArterial Extracorporeal Membrane Oxygenation (VA-ECMO), and Impella, among others.
RESUMEN
Acute myocardial infarction can result in various mechanical complications, although they have become rare with the advent of reperfusion therapies. Among these complications, ventricular septal rupture (VSR) and left ventricular aneurysm (LVA) are infrequent but life-threatening conditions associated with high morbidity and mortality. We present a rare case of a 67-year-old male with acute myocardial infarction who developed concomitant apical LVA and ventricular septal rupture. LEARNING POINTS: Mechanical complications of myocardial infarction, such as a ventricular septal rupture (VSR) and left ventricular aneurysm (LVA), are rare but life-threatening.Early diagnosis is critical. A ventricular septal defect (VSD) requires immediate surgical closure, while surgery for LVA is only considered in specific cases such as chest pain or thromboembolism.Diagnostic tools such as echocardiography and left ventriculography play a vital role in identifying and characterising these complications, enabling timely treatment decisions.
RESUMEN
Myocarditis is a rare extraintestinal manifestation of inflammatory bowel disease. Myopericarditis-associated inflammatory bowel disease can be a side effect of the medications used to treat inflammatory bowel disease or the disease process. We present a 25-year-old female with history of ulcerative colitis presented with abdominal pain associated with sharp and central chest pain. She was in a flare of ulcerative colitis with bloody diarrhea. She developed shock and was in intensive care unit. Echocardiogram showed reduced ejection fraction and pericardial effusion. Coronary artery disease, sepsis, thyroid disease were ruled out. She was treated with systemic antibiotics, intravenous steroids, and guideline-directed medical therapy for presumed ulerative colitis associated with myopericarditis and had symptomatic improvement. Treatment of IBD-associated myopericarditis includes the standard induction treatment for IBD with steroids and guideline-directed medical therapy for heart failure.
RESUMEN
BACKGROUND Acute aortic insufficiency can be secondary to multiple conditions, including infective endocarditis, aortic root pathologies (eg, dissection, aortitis), or traumatic injury. Aortitis involves a broad spectrum of disorders characterized by inflammatory changes in the aortic wall. This pathology can be subsequently classified depending on its etiology into inflammatory and infectious causes. Large-vessel vasculitis (giant-cell arteritis, Takayasu arteritis, and IgG4-related vasculitis) is the most common non-infectious causes of aortitis. Giant-cell aortitis usually lacks the classic clinical findings of giant-cell arteritis such as headache, visual symptoms, or jaw claudication, which can be a diagnostic challenge. However, clinicians should have a high index of suspicion, since this pathology can evolve into potentially life-threatening conditions, including aortic aneurysm, aortic wall rupture, and aortic acute dissection. CASE REPORT We present a case of a 76-year-old woman who presented to the Emergency Department (ED) with shortness of breath associated with orthopnea, paroxysmal nocturnal dyspnea, and mild productive cough with white sputum. A transthoracic echocardiogram demonstrated reduced left ventricular ejection fraction, dilated left ventricle, and severe aortic insufficiency. Cardiac catheterization revealed mild non-obstructive coronary arteries and severe aortic regurgitation. The surgical pathology report of the portion of the aorta was consistent with giant-cell aortitis. CONCLUSIONS In this article, we present a case of giant-cell aortitis as an unusual etiology of acute aortic insufficiency, which is most probably under-detected in clinical practice. In addition to describing the case, we aim to highlight the importance of proper ascending aorta evaluation in patients presenting with new-onset aortic regurgitation and heart failure to prevent associated morbidity and mortality.

The left ventricular outflow tract is a region of the left ventricle that lies between the anterior leaflet of the mitral valve and the ventricular septum. Dynamic left ventricular outflow tract obstruction (LVOTO) has classically been observed in patients with hypertrophic obstructive cardiomyopathy (HOCM) where it occurs secondary to asymmetric septal hypertrophy and systolic anterior motion (SAM) of the mitral valve. However, there are some instances that lead to hypercontractility of the myocardium, and with a combination of other physiological conditions, result in SAM of a mitral valve leaflet, leading to LVOTO in the absence of phenotype. We present such a case of an acute inferolateral wall myocardial infarction that was complicated by cardiogenic shock, requiring an intra-aortic balloon pump (IABP) and inotropic support which paradoxically provoked LVOTO. A reduction in IABP counterpulsation from 1:1 to 1:3 and the addition of intravenous fluids and a beta blocker resulted in significant improvement in blood pressure with rapid tapering of pressors. Inotropes and IABP, although helpful in cardiogenic shock, have the potential to induce or worsen the LVOTO, which can lead to a vicious cycle of worsening hypotension and increasing adrenergic drive that further deteriorates myocardial viability. Timely diagnosis with an echocardiogram and the withdrawal of inotropic and IABP support has the potential to improve haemodynamics and, thereby, outcome. LEARNING POINTS: Dynamic left ventricular outflow tract obstruction (LVOTO) should be one of the differentials in patients with cardiogenic shock, especially if it is refractory in the setting of an intra-aortic balloon pump.The diagnosis of LVOTO by echocardiography should result in immediate implementation of therapy to eliminate the factors that can potentially intensify the obstruction.
RESUMEN
A pericardial cyst is one of the rare causes of mediastinal masses. Most of the cases are secondary to congenital incomplete fusion of the pericardial sac. More than two-thirds of the cases are present in the right cardiophrenic angle, and the left cardiophrenic angle is the second most common location. In our study, we illustrated an incidental finding of the pericardial cyst in a patient who presented with nonspecific symptoms and was found to have a left-sided cardiophrenic pericardial cyst, which is only found in about 20% of the cases. A CT scan and echocardiogram confirmed the diagnosis of a 4.39-centimeter cyst with no signs of complications like tamponade or pericarditis. As the patient's symptoms resolved, outpatient follow-up with serial echocardiogram was advised. Through this report, we aim to raise awareness of the importance of further investigation for nonspecific symptoms like atypical chest tightness and differentiating simple pericardial cysts from other pericardial lesions. Based on the symptoms, size, and compression effect of the cyst, management may vary from serial echocardiogram to aspiration or surgical resection.
RESUMEN
Cocaine is considered a leading non-opioid cause of drug overdose in the US. It acts as a sympathomimetic and increases the amount of catecholamines, thereby increasing the risk of ventricular irritability and resultant arrhythmias. Its sodium (Na) channel blockage is the principal mechanism behind the Brugada pattern on an electrocardiogram (ECG), which is often transient but is indistinguishable from that of Brugada syndrome, the autosomal dominant channelopathy. We are presenting a case of a 32-year-old male with a history of cocaine and nicotine abuse, who sought medical attention for sudden-onset palpitations and pressure-like chest pain after having snorted an impressive amount of cocaine. His ECG depicted a classical Brugada pattern with ST-elevation with T inversion in V1; however, previous ECGs were normal without ST changes, signifying the Brugada pattern unmasked by cocaine use. Other investigations including stress tests and nuclear imaging were equivocal. His symptoms as well as the ECG pattern reverted to baseline signifying the presence of Brugada phenotype in the absence of channelopathy. Hence, as a sodium channel blocker, cocaine may unmask latent Brugada syndrome in asymptomatic patients without a family history. Recognizing Brugada syndrome on ECG is vital to avoid misdiagnosis and mistreatment of the patient with and without a genetic predisposition.
RESUMEN
Aortic dissection is a relatively uncommon, although catastrophic, disease which requires early and accurate diagnosis and treatment for patient survival. Aortic dissection can be difficult to diagnose due to the diverse symptom presentation, which can lead to later diagnosis, resulting in a higher mortality rate. Here we present a case of type A aortic dissection with a varied symptom presentation, highlighting the importance of early detection and the Bentall procedure for management of such cases. A 50-year-old man with no known medical history presented with bilateral lower extremity swelling and fatigue for 2 weeks. The patient denied any chest pain or dyspnoea. Vital signs showed blood pressure of 160/76 mmHg, pulse of 103 bpm, respiratory rate of 18, and temperature of 36.7°C. Laboratory findings indicated a BNP of 1901 pg/ml and troponin of 0.5 ng/ml. An initial diagnosis of decompensated heart failure was made, and IV Lasix was started. Subsequently, an echocardiogram indicated an EF of 50-55% and ascending dissection of the aorta. A CT angiogram of the chest and abdomen confirmed this diagnosis. This patient presented with unusual symptoms of aortic dissection without the typical presentation of chest pain. It is important to consider aortic dissection in a cardiac-related case as prompt imaging can help confirm the diagnosis. We explore the risks and benefits of the Bentall procedure for the management and early detection of aortic dissection. LEARNING POINTS: The absence of chest pain does not rule out aortic dissection as 50% of patients are pain free.It is critical to diagnose aortic dissection early in the disease course as mortality increases by 1% per hour from symptom onset.The aim of this study is also to raise awareness among healthcare professionals about the Bentall procedure in patients with type A aortic dissection involving the aortic valve.
RESUMEN
Brugada syndrome is a rare arrhythmogenic syndrome that is associated with an increased risk of ventricular fibrillation and sudden cardiac death. Electrocardiographic findings include patterns similar to a right bundle branch block (RBBB) and persistent ST-segment elevation in precordial leads (V1 and V2). There are numerous reports of Brugada syndrome mimicking ST-segment elevation myocardial infraction (STEMI); however, we describe a case of 47-year-old male who presented with STEMI mimics Brugada syndrome with preexisting RBBB. The patient developed polymorphic ventricular tachycardia generating into ventricular fibrillation right before catheterization making the diagnosis more challenging. The patient, eventually, was found to have obstructive coronary artery disease and no evidence of abnormal sodium channelopathy on further testing. This case highlights the importance of meticulous history taking and appropriate diagnostic test in establishing proper diagnosis of STEMI in a patient with preexisting RBBB, which can mimic Brugada syndrome.

Spontaneous Coronary Artery Dissection (SCAD) is one of the nonatherosclerotic causes of Acute Coronary Syndrome. It's extremely rare for SCAD to present in an asymptomatic male, with incidental finding of Left Ventricular (LV) thrombus on echocardiogram. This report presents the case of a 36-year-old male with such an atypical presentation of Spontaneous Coronary Artery Dissection with Left Ventricular apical thrombus as a complication. The patient received successful medical management, with excellent clinical outcomes. This case highlights the importance of an early recognition and treatment strategy for both conditions using medical therapy.
RESUMEN
Spasm following coronary artery bypass graft surgery has been well established in arterial grafts, especially in grafts utilizing the internal mammary. Venous graft spasms are uncommon and are only observed in vein grafts during or soon after the coronary artery bypass surgery. It is exceedingly rare to see spasm of venous graft beyond one year of surgery. We report a 72-year-old female who had coronary artery bypass graft three years ago and presented with new onset chest pain for one month. The coronary angiogram revealed severe spasm of the proximal aspect of a patent saphenous venous graft which was relieved by intracoronary nitroglycerine. Patient was successfully managed using combination of anti-spasmodic medications (nitrates and calcium channel blockers) leading to long-term resolution of her anginal symptoms.

Coronary artery fistulas are rare anomalies of the coronary arteries that may sometimes cause symptoms by shunting blood flow away from the myocardial capillary network. We report the case of a 46-year old lady which shows the right coronary cusp giving rise to left main coronary artery called anomalous origin of a coronary artery (AOCA), and also a fistula between the left coronary artery and pulmonary artery. We describe our diagnostic approach and review the literature on the epidemiology, pathophysiology, the diagnostic modalities, and treatment options.
