Madalena Coutinho Cruz, Isabel Luiz, Lurdes Ferreira, Rui Cruz Ferreira
Wellens' syndrome is characterized by an electrocardiographic pattern of T-wave changes associated with a critical stenosis of the left anterior descending artery (LAD), which progresses to an extensive anterior myocardial infarction in the majority of cases. For this reason, its recognition and early treatment are extremely important. We report 2 cases of Wellens' syndrome: an 83-year-old male presenting with ill-characterized chest pain, biphasic T waves in V1-V3 during an asymptomatic period, negative cardiac biomarkers, and a 64% stenosis in LAD with a fractional flow reserve of 0...

Fluconazole for fungal infections and amiodarone for arrhythmia are commonly prescribed medications, and coadministration of such medications is sometimes inevitable in clinical practice. However, both medications have been associated with prolonged QTc intervals and subsequent arrhythmias, which are sometimes fatal. We present the case of a 75-year-old man with sudden cardiac arrest triggered by coadministration of fluconazole and amiodarone, which raises the need for caution regarding coadministration of these medications...

Sleep-disordered breathing (SDB) is highly prevalent in patients with heart failure (HF), and is known to be associated with a worse prognosis. The severity of central sleep apnea is thought to mirror cardiac dysfunction. The novel angiotensin receptor-neprilysin inhibitor (ARNi) sacubitril has been shown to improve HF, but a relationship between treatment with ARNi and the severity of SDB has not yet been investigated. We report the case of a 71-year-old male with HF and SDB. Treatment with sacubitril/valsartan was associated with improved cardiac function, as shown by a reduction in the level of N-terminal prohormone of brain natriuretic peptide from 3,249 to 1,720 pg/mL, and an improvement in left-ventricular ejection fraction from 30 to 35%...

BACKGROUND: The optimal strategy to manage chronic total occlusion (CTO) remains unclear. The Japanese CTO multicenter registry (J-CTO) score is an established tool for predicting successful recanalization. However, it does not take into account nonangiographic predictors for final technique success. In the present study, we designed and tested a scoring model called the Busan single-center CTO registry (B-CTO) score combining clinical and angiographic characteristics to predict successful CTO recanalization in Korean patients...

Rong Yu, Lv Liu, Chan Chen, Jin-Mei Shen
OBJECTIVES: Dilated cardiomyopathy (DCM) is a common disease in the clinic, and it is the leading cause of heart failure and sudden cardiac death. Previous studies have proven that genetic factors play a crucial role in the occurrence of DCM; more than 50 disease genes including desmin (DES) have been identified to be associated with DCM. At present, most DES mutations are reported in desmin-related myofibrilla myopathy patients, but variants leading to isolated DCM are rarely reported...

We report on the clinical, biochemical, and genetic findings of a large family with the classical phenotype of Fabry disease due to the novel nonsense mutation c.607G>T (p.E203X) of the GLA gene, which occurs in the active site of the α-galactosidase A enzyme. This report highlights that (i) Fabry disease diagnosis should be considered in all cases of unexplained left ventricular hypertrophy (LVH), even in its milder forms; (ii) a complete evaluation of patients with unexplained LVH is important to find diagnostic red flags of treatable causes of LVH, such as Fabry disease; (iii) cascade family screening is paramount to the earlier diagnosis and treatment of other affected family members; and (iv) the Fabry disease phenotype is highly variable in heterozygote females, even within the same family...

Tafamidis meglumine is a novel medicine that has been shown to slow the progression of peripheral neurological impairment in patients with hereditary transthyretin amyloidosis (ATTR). However, the efficacy of tafamidis against ATTR-related cardiac amyloidosis remains unclear. A 72-year-old woman had cardiac hypertrophy and axonopathy in her lower legs. Endomyocardial biopsy revealed an infiltrative cardiomyopathy consistent with amyloidosis. Immunostaining and genetic studies confirmed the diagnosis of ATTR, and tafamidis was started subsequently...

OBJECTIVES: Current nonpharmacological therapies for symptomatic patients with hypertrophic obstructive cardiomyopathy (HOCM), including septal myectomy and alcohol septal ablation (ASA), carry significant risks for serious cardiac conduction abnormalities. We present a review of the currently available published data regarding the novel use of the relatively low-risk MitraClip® system in the treatment of symptomatic patients. METHODS: Data were collected from 4 separate studies on the use of the MitraClip on 15 symptomatic HOCM patients with systolic anterior motion (SAM) of the mitral valve apparatus...

BACKGROUND: The overproliferation of pulmonary vascular cells is noted in pulmonary hypertension. The role of exosomes from pulmonary artery endothelial cells (PAEC) in the proliferation and apoptosis of pulmonary artery smooth muscle cells (PASMC) remains unclear. METHODS: Exosomes were isolated and purified from the culture medium of PAEC using a commercial kit. Lipopolysaccharide (LPS), hypoxia, and hydrogen peroxide were utilized to induce PAEC injury. Coculture of PAEC and PASMC was conducted using Transwell plates, and GW4869 was applied to inhibit exosome release...

OBJECTIVES: Transcatheter aortic valve implantation (TAVI) is frequently associated with the development of conduction abnormalities. We assessed the effect of conduction abnormalities on diastolic function following TAVI. METHODS: In total, 101 consecutive post-TAVI patients were included, each with echocardiographic follow-up at 1 and 6 months. Diastolic properties were correlated with the occurrence of a long PR interval and wide QRS, and their change from baseline...

OBJECTIVES: To compare angiographic and optical coherence tomography (OCT) data pertinent to thrombi, along with the histologic characteristics of aspirated thrombi in patients presenting with ST elevation myocardial infarction (STEMI) with or without inflammation, as assessed by C-reactive protein (CRP) and myeloperoxidase (MPO). METHODS: In the OCTAVIA (Optical Coherence Tomography Assessment of Gender Diversity in Primary Angioplasty) study, 140 patients with STEMI referred for primary percutaneous intervention were enrolled...

We report the case of a woman in her 70s presenting to the emergency department with syncope, troponemia, and an electrocardiogram with deep symmetric T-wave inversions in V2 and V3 and prolonged QTc. Her presentation was concerning for acute coronary syndrome, Wellens syndrome in particular, given the elevated troponin levels, lack of ST segment changes, and characteristic T-wave findings. The diagnosis was confirmed with angiography that showed a critical left anterior descending (LAD) artery occlusion. Since myocardial infarction does not typically present with syncope, we explored the differential diagnoses for T-wave inversions, which include electrolyte abnormalities, medications, intracranial hemorrhage, pulmonary embolism, and other cardiac diseases that were ruled out in our patient...

BACKGROUND: We aimed to compare periprocedural transesophageal echocardiography (TEE) with postprocedural transthoracic echocardiography (TTE) for the diagnosis of aortic regurgitation (AR). METHODS AND RESULTS: TEE and TTE images of 163 transcatheter aortic valve replacement (TAVR) patients (mean age 81 ± 8 years; 56% men) were reviewed separately and blinded to each other as well as to all clinical data. The median time between TEE during TAVR (TEE/TAVR) and TTE was 4 days (IQR 2-10 days)...
