A 66-year-old man with a history of palpitations suggestive of paroxysmal supraventricular tachycardia was referred for CT angiography (CTA) for exertional dyspnea etiology investigation. ECG-gated cardiac CT was performed using the 64-slices dual-source Somatom Go Scanner. CTA showed the normal origin of the right and left main coronary arteries, and there was no evidence of obstructive coronary artery disease. The proximal right coronary artery (RCA) had a normal epicardial course, but mid-RCA was noted to penetrate the right atrial wall […]

The complex post-surgical anatomy after the Senning procedure presents several challenges for catheter ablation. Transbaffle approach allows access to the pulmonary venous atrium and better catheter manipulation. However, this modified transseptal puncture can be challenging to perform. The authors present the case of a 29-year-old woman who underwent a Senning procedure for dextro-transposition of the great arteries. The patient had recurrent episodes of atrial flutter despite adequate antiarrhythmic therapy and was referred for catheter ablation. […]

A 54-year-old male patient, who was a smoker, was admitted to the emergency room with acute chest pain and dyspnea. Investigation was initiated by means of computed tomography angiography of the chest, which showed extensive dissection of the thoracic aorta, beginning in the ascending segment (Stanford type A), associated with intramural hematoma of the pulmonary artery trunk and its main branches. It was more evident on the right, which determines local pulmonary luminal reduction, in addition to a small para-aortic […]

A diabetic 65-year-old male with previous Bentall procedure and mechanical aortic valve prosthesis presented with fever and abdominal pain, along with systolic murmur (III/VI) and elevated inflammatory markers. Abdominal computed tomography (CT) revealed splenic infarction. Transesophageal echocardiogram (TEE) was negative for vegetations. Given the persistent suspicion of infective endocarditis (IE) with peripheral embolism, empirical antimicrobial therapy was initiated. The patient subsequently presented with complete atrioventricular block, requiring temporary transvenous pacing. An epicardial pacemaker was later implanted. At the time, cardiac […]

Wild-type transthyretin amyloid cardiomyopathy (wt-ATTR-CM) is increasingly recognized due to the recognition of the increasing prevalence, advances in diagnostic methods, and the development of effective treatments. We report the case of an 88-year-old female with history of hypertension, chronic kidney disease (CKD), heart failure with preserved ejection fraction, and no relevant family history. She presented to the emergency department with history of syncope, productive cough, worsening dyspnea, and fever. The auscultation showed a grade III/VI systolic murmur in her left […]

Case Report A 32-year-old young man, without cardiovascular risk factors, sought an Emergency Unit due to severe chest pain 30 minutes before admission, without irradiation. Admission vital signs: T 36.1°C, heart rate of 89 bpm and peripheral O2 saturation of 96% in room air. During systematic interrogation, anosmia and ageusia were reported two days ago and fever or any other respiratory symptom was denied. He was previously healthy and denied use of illicit drugs or previous history of angina. He […]

Wellens Syndrome, also known as “Anterior Descending Coronary T-wave syndrome”, was described in 1982 by Dr. Henrick Joan Joost (Hein) Wellens, a Dutch physician who also contributed to the characterization of the reentry mechanism in Wolff–Parkinson–White syndrome (WPWS). Originally described during hospital admission (60% at admission and 40% at the follow-up) of patients with unstable angina, it was characterized by the occurrence of 2 electrocardiographic patterns, with pattern A in 25% of patients and B in 75% of patients. […]

Abstract We present a case report of a patient with an infected mitral valve myxoma and a literature review on the subject. A 33-year-old female presented with a history of fever and dyspnea evolving over a few days. On admission, she had a lupus-like syndrome with positive blood cultures for Haemophilus species . Echocardiogram revealed a giant mass involving both mitral leaflets causing severe regurgitation, requiring biological mitral valve replacement. Microscopy showed an infected myxoma and the patient was discharged […]

A 2.7 kg term neonate was diagnosed on day 3 of life with Ebstein’s anomaly of the tricuspid valve, severe tricuspid regurgitation, valvar pulmonary atresia and duct-dependent pulmonary circulation. The cardiothoracic ratio was 90%, and GOSE score was 1.48. Oxygen saturation was 65% and improved to 88% on 0.005 mcg/kg/min of prostaglandin. The right ventricular systolic pressure was 40mmHg against a systolic blood pressure of 65mmHg. The child was taken up for stenting of the arterial duct on day 7 […]

An 18-year-old male patient presented to our ambulatory services due to a 3-month course of progressive dyspnea and non-productive cough. Symptoms were present even at rest, and he exhibited severe limitation at physical activity. He had a diagnosis of glycogen storage disease (GSD) type IV attained by liver biopsy since three years of age, when he developed hepatomegaly and mild hepatic dysfunction. At the time, histopathological examination showed grade 2 fibrosis along with numerous intracytoplasmic PAS-positive deposits that were resistant […]
