Osborn waves, or J waves, initially described by John Osborn in 1953 in hypothermic dog experiments, are highly sensitive and specific for hypothermia. Initially thought to be secondary to a hypothermia-induced "injury current," they have more recently been attributed to a voltage differential between epicardial and endocardial potassium (Ito ) currents. While the exact conditions required to induce such waves have been debated, numerous clinical scenarios of environmental and iatrogenic hypothermia have been described...

Over the past five decades, the incidence of intravenous drug use- (IVDU-) associated infective endocarditis (IE) has been on the rise in North America. Classically, IVDU has been thought to affect right-sided valves. However, in recent times a more variable presentation of IVDU-associated IE has been reported. Here, we report a case of a patient with a known history of IVDU who presented with clinical symptoms concerning for right- as well as left-sided endocarditis. In addition, we also discuss what should be considered adequate evaluation for patients with suspected endocarditis, and more specifically, what should be the role of transesophageal echocardiography in patients with IE noted on transthoracic echocardiography...

Cardiovascular disease is common among patients with chronic obstructive pulmonary disease (COPD). Takotsubo syndrome (TTS) is a transient cardiac disorder that, in its typical form, involves left ventricular dysfunction with apical ballooning and mimics acute coronary syndrome (ACS). "Bronchogenic TTS" has been proposed as a specific form of TTS (during severe acute dyspnea in asthma or COPD) with atypical presentation. Recurrent TTS in COPD seems to be exceptionally rare since only a handful of clinical cases have previously been reported in the literature...

Simultaneous arteriovenous embolism is extremely rare. Herein, we present a rare case of systemic arteriovenous emboli in a healthy 33-year-old male after an episode of acute viral perimyocarditis. The culprits are postulated to be viral-induced myocardial necrosis and resulting proinflammatory state in the setting of negative malignant, autoimmune, genetics, and chronic infectious conditions. The patient was successfully managed with guideline-directed medical therapy and safely discharged to a subacute rehabilitation facility...

Cardiac contractility modulation (CCM) is an investigational device-based therapy to enhance ventricular contractility in systolic heart failure patients who are not candidates for cardiac resynchronization therapy (CRT) owing to the absence of wide QRS complexes or who have failed to respond on CRT. The principal mechanism is based on the stimulation of cardiac muscles by nonexcitatory electrical signals to augment the influx of calcium ions into the cardiomyocytes. The majority of patients receiving CCM therapy have concurrent implantable cardioverter defibrillators, and the manufacturer declares both devices can be used in parallel without any interactions...

There is an increasing prevalence of cardiac implantable electronic devices (CIEDs) due to expanding adoption and availability of these evidence-based therapies. With the increased prevalence of these life-saving devices, there has also been an increased demand for lead removal and lead extraction. Understanding the specific subgroups of patients at high risk for complications during and after lead extraction has become imperative to properly manage endovascular CIED leads. There have been multiple published studies describing clinical variables that predict adverse outcomes in CIED system extractions; however, the risk of complications in leads placed after cardiac transplantation has not specifically been addressed to date...

We present a case of a complete atrioventricular block (AV block) with different aberrancy patterns during sinus rhythm and escape rhythm. A 66-year-old woman visited our emergency department complaining of sudden onset dizziness and fatigue over the past thirty minutes. Her medical history was remarkable for arterial hypertension, type 2 diabetes mellitus, and hypothyroidism. The patient had a known Left Bundle Branch Block (LBBB) on past ECGs. Upon palpation of peripheral pulse, a measurement of 32 beats per minute was obtained...

Loeys-Dietz syndrome is a rare autosomal dominant connective tissue disorder notable for rapidly progressive vascular aneurysmal disease and craniofacial defects. Patients are at an increased risk for aneurysm rupture and dissection at younger ages compared to other aneurysmal syndromes. Early surgical intervention is important for prevention of ruptures and/or dissection. The coronary arterial tree is mostly involved as a result of postoperative complications of an aortic root repair. This fact has been sparsely reported...

The advent of percutaneous coronary intervention (PCI) has dramatically changed the outlook for patients with cardiovascular disease. However, room for improvement and advancement remains in the safety, speed, and efficiency of manually guided PCI. In recent years, the CorPath robotic platform (Corindus Inc., Waltham, MA) has been approved to aid the interventionalist during PCI and other endovascular interventions. Favorable results in several clinical studies suggest that robotic-assisted PCI may further improve patient outcomes while also benefiting the interventionalist through reduced orthopedic strain and less exposure to ionizing radiation...

Cardiac amyloidosis is a rare disease, and its prevalence varies depending on the type of amyloid protein involved. Several case reports make reference to the increased risk of thrombosis and thromboembolic events in cardiac amyloidosis. We report a case of rapidly evolving, multichamber thrombi in a patient who was ultimately diagnosed with wild-type TTR cardiac amyloidosis.

Congenital defects of the coronary arteries are noted in 0.2-1.4% of the general population. The first case of an anomalous origin of right coronary artery from pulmonary artery (ARCAPA) was described by Brooks in 1885. ARCAPA has an overall incidence of 0.002% in the general population. Most of the cases are asymptomatic; however, it can lead to serious complications such as heart failure, ischemia, and sudden death. A 57-year-old man presented to the cardiologist's office with complaints of shortness of breath and fatigue...

A 73-year-old female with multiple comorbidities including coronary artery disease was admitted for an elective PCI of a lesion detected in the RCA. On the day of the planned PCI, shortly after right femoral artery cannulation, the patient developed a sudden complete heart block requiring the administration atropine and insertion of a temporary pacemaker. Concomitantly, the patient developed acute pulmonary edema, hypotension, and hypoxia requiring intubation for mechanical ventilation. Vasopressors were administered...

ST segment changes are well documented in literature during supraventricular tachycardias. We present a case of a 21-year-old male who presents with chest pain, shortness of breath, and dizziness with an ECG showing atrioventricular reentrant tachycardia and diffuse ST segment depressions. Patient spontaneously converted to sinus rhythm, but he was still complaining of crushing chest pain. ECG taken after conversion showed sinus rhythm at a rate of 65 and showed obvious persistence of ST depressions in majority of leads...

Left ventricular false tendons (LVFTs) are linear fibrous or fibromuscular bands stretching across left ventricular cavity. Although LVFTs have been associated with various heart pathologies and investigated embryologically and histologically, there is only one report in the literature connoting possible hereditary transmission of this entity. We reported a father and his daughter having similar types of LVFTs with regard to location and thickness. With this report, we will contribute in the literature in respect to potential genetic inherence of LVFTs...

Inferior vena cava (IVC) diameter and respirophasic variation are commonly used echocardiographic indices to estimate right atrial pressure. While dilatation of the IVC and reduced collapsibility have traditionally been associated with elevated right heart filling pressures, the significance of isolated IVC dilatation in the absence of raised filling pressures remains poorly understood. We present a case of an asymptomatic 28-year-old male incidentally found to have IVC dilatation, reduced inspiratory collapse, and normal right heart pressures...

Stress-induced cardiomyopathy, also known as Takotsubo cardiomyopathy, presents as an acute coronary syndrome. However, the physiology and pathogenesis are different. It is imperative to treat stress-induced cardiomyopathy as an acute coronary syndrome, and once diagnosed, it is imperative to assess and treat heart failure and wait for the impaired myocardial energetics to resolve. At times, the myocardial recuperation is quick that we miss the diagnosis of Takotsubo cardiomyopathy.

Left ventricular outflow tract (LVOT) obstruction is sometimes observed in patients with severe aortic stenosis (AS). It is still controversial how to manage the remaining severe AS, when LVOT obstruction is well-controlled by medical therapy. We report a case with acute recurrence of LVOT obstruction requiring emergent alcohol septal ablation (ASA) after transcatheter aortic valve implantation (TAVI), even in a stable state on beta-blockers. For the ASA procedure, transesophageal echocardiography was useful to clearly observe the perfusion area of the target septal branch by injecting microbubble contrast...

Pericardial cysts are an uncommon cause of mediastinal masses and may be found incidentally on imaging. Symptoms commonly include cough, chest pain, and shortness of breath elucidating a broad differential on examination. Diagnosis is predominantly made using imaging modalities, such as CT, MRI, and CXR with treatment including resection for symptomatic cysts and observation for asymptomatic cysts. Due to a lack of specific signs and symptoms towards identifying pericardial cysts, many are identified at a later stage requiring resection by video-assisted thoracoscopic surgery (VATS)...

Cardiovascular symptoms remain the most common presenting features and leading causes of death in hyperthyroidism. We report a young female with reported thyroid disease and medication noncompliance presenting with atrial fibrillation, severe atrioventricular regurgitation, severely dilated right heart with reduced function, and moderate pulmonary hypertension (PH), which was further complicated by congestive liver injury with ascites and pancytopenia. Thyroid work-up revealed suppressed TSH, elevated free T4 and T3 along with elevated anti-thyroglobulin antibodies, thyroid peroxidase antibodies, and thyroid-stimulating immunoglobulin, suggesting Graves' thyrotoxicosis...
