syncope/dental caries

BACKGROUND Current guidelines do not support the routine use of computed tomography (CT) scan of the head in the diagnostic workup of syncope. There is a lack of research to support whether these guidelines apply to the Black population. OBJECTIVE This study aims to evaluate the yield of

BACKGROUND Syncope and sudden death in hypertrophic cardiomyopathy may have a hemodynamic basis. The presence of a small ventricular cavity with high intracavity pressures may activate left ventricular baroreceptors and cause reflex hypotension as described in other populations with

Giant fibrovascular polyp of the esophagus is a rare but dramatic entity. These large polyps arise in the proximal esophagus and can cause airway obstruction secondary to mechanical pressure on the larynx, or they can present as a mass that is regurgitated into the oral cavity. We present a

In Doppler echocardiography, testing left ventricular outflow tract (LVOT) gradient in the supine position (as is done in everyday practice) does not reflect the pathophysiology of this dynamic abnormality during the daily activities that trigger the symptoms (eg, syncope). LVOT obstruction is a

Cardiac involvement in echinococcosis remains a singular finding, possibly associated with confusing symptomatology. We report the original case of a 17 year-old young woman, referred to our cardiology department for repeated exertion syncopes, and ultimately, proven through echocardiography,

A 76-year-old woman suffered from repeated postprandial syncope of unknown cause. Computed tomography scanning revealed an enlarged hiatal hernia sac with food residues that compressed both the left atrium and inferior vena cava. As soon as the hernia cavity expanded during an upper gastrointestinal

BACKGROUND Although extensively investigated, the mechanism(s) of post-spaceflight orthostatic intolerance has not been elucidated. Several researchers have proposed that the "trigger" for syncope is an empty ventricle, initiated when a hypercontractile state, possibly due to a sudden surge in

The aim of this study was to assess whether left ventricular (LV) cavity size relates to functional impairment and syncope in patients with hypertrophic cardiomyopathy (HC). LV diastolic dysfunction influences functional limitation in HC. A reduced LV end-diastolic dimension may underlie impaired

A 78-year-old man who suffered from syncope and light-headedness during straining. The patient visited to our department for evaluation of his symptom. Cardiac auscultation revealed a grade II/IV systolic murmur along the left parasternal border. Electrocardiography showed T wave inversion at the

A 12-year-old male child presented with recurrent syncope. Ventricular tachycardia was noted on the electrocardiogram. Transthoracic echocardiogram revealed a homogeneous tumor mass in the right ventricular cavity with extension into the outflow region. Left cervical lymph node biopsy confirmed the

A healthy man in his 30s was working on the balustrade of stairs on the second floor. He suddenly fell downstairs without saying anything. On emergency hospitalization, chest echogram showed left hemothorax. Cardiac echogram showed a floating mass from the mitral valve in the left ventricle and

BACKGROUND Right atrial myxoma accounts for 15-20% of cardiac myxomas and syncope is a very rare manifestation. We present the case of an 89-year-old man with right atrial myxoma and syncope, and discuss the role of cardiac magnetic resonance imaging (MRI) in the diagnosis of myxomas. METHODS An

BACKGROUND Hiatal hernias are common. In some reports, hiatal hernias have been implicated in causing dyspnea, syncope, and heart failure. METHODS An 82-year-old woman with a hiatal hernia was admitted to our hospital because she had experienced postprandial syncope during the last few years.
