Facing the pandemic with a smile: the case of Memedical and its impact on cardiovascular professionals.

Since its outbreak, the Coronavirus disease 2019 (COVID-19) has profoundly changed the world we were acquainted with. After the first known contact with humankind in Wuhan, China, in December 2019, the reckless spread of such pathogen put the healthcare system to the test, leading to harmful consequences affecting human lives in every aspect. As of February 2022, the death toll amounts to almost 6 million deaths, but the pathogenic profile of SARS-CoV-2 goes way beyond the mere biological interaction between the viral particle and our organism. People had to deal with the severe psychological impact caused by the only available weapon to fight this infection, i.e., social distancing. The human psychological profile has been strained with repercussions we still are unaware of nowadays. Healthcare professionals were among the most hit categories, not only because of the quarantine but above all for the situations they had to bear every day, constantly facing desperation, death, isolation, and rage. In such circumstances, social media represented a powerful shelter, giving people the ability to keep in contact and to feel connected even if miles apart. In our country, the power of communication was strongly emphasized by launching an Italian Facebook group called "Memedical," where members can share ironic memes to feel closer and give a glimmer of happiness in such a challenging moment. Our review highlights the severity of this pandemic's impact, deteriorating the global population's physical and mental health, and shows how wise use of social media can benefit the quality of life.

Lipomatous Hypertrophy of the Interatrial Septum: A Case Report and Insights from the Literature.

Lipomatous hypertrophy of the interatrial septum (LHIS) is a histologically benign cardiac lesion that is defined by excessive fat accumulation in the area of the interatrial septum (IAS) that does not include the fossa ovalis. Another unusual illness is lipomatosis, which is defined as a broad overgrowth of mature adipose tissue that involves a large portion of an extremity or trunk. We describe a rare case with significant LHIS accompanied by subcutaneous lipomatosis. Echocardiography revealed a mass in the right atrium in this patient. Magnetic resonance imaging revealed that this mass was composed of the adipose tissue and was an extension of a huge thickened IAS. Furthermore, this significant hypertrophy of the IAS was in direct continuation with the excessive mediastinal and epicardial fat.

Nonbacterial Thrombotic Endocarditis with Atypical Presentation as Overt Congestive Heart Failure.

Nonbacterial thrombotic endocarditis (NBTE) is a form of endocarditis associated with malignancy or autoimmune disorders. Diagnosis remains a challenge as patients are often asymptomatic up to embolic events or rarely, valve dysfunction. We report a case of NBTE with uncommon clinical presentation and identified with multimodal echocardiography. An 82-year-old man presented to our outpatient clinic reporting dyspnea. Past medical history included hypertension, diabetes, kidney disease, and unprovoked deep-vein thrombosis. On physical examination, he was apyretic, mildly hypotensive, and hypoxemic, had a systolic murmur and lower limbs edema. Transthoracic echocardiography revealed severe mitral regurgitation due to verrucous thickening of the free margin of both leaflets, increased pulmonary pressure, and dilated inferior vena cava. Multiple blood cultures were negative. Transesophageal echocardiography confirmed "thrombotic" thickening of mitral leaflets. Nuclear investigations were highly suggestive of multi-metastatic pulmonary cancer. We did not further proceed with the diagnostic workup and prescribed palliative care. Lesions seen on echocardiography were suggestive of NBTE: they involved both sides of mitral leaflets, close to the edges, had irregular shape and echo density, a broad base, and no independent motion. Criteria for infective endocarditis were not met and the final diagnosis was paraneoplastic NBTE due to underlying lung cancer. We remark the lack of definitive recommendations about the treatment of NBTE and the only role of anticoagulation to prevent systemic embolism. We have reported a case of NBTE presenting with atypical symptoms and likely related to the prothrombotic state induced by underlying lung cancer. Provided the unconclusive microbiological tests, multimodal imaging has played a crucial role in the final diagnosis.

Impact of vascular access on acute kidney injury after percutaneous coronary intervention.

OBJECTIVES: We performed a systematic review of the literature and a meta-analysis to examine the role of access site in affecting the incidence of acute kidney injury (AKI) after percutaneous coronary intervention (PCI). BACKGROUND: The vascular access site may play a central role among procedure-related risk factors for AKI after PCI. Transradial access is associated with reduced vascular complications and major bleeding which, in turn, is an emerging risk factor for post-procedural AKI. METHODS: Results of six observational studies, three out of six providing propensity matching adjustment, of patients undergoing PCI from the radial and the femoral access were pooled, including overall 26,185 patients. The endpoint was the incidence of study-defined AKI. A meta-regression analysis was performed to further assess the role of study-level covariates. Random-effects models were privileged. RESULTS: There was a significant difference in the incidence of AKI after PCI, favoring radial access (odds ratio [OR] 0.51, 95% CI 0.39-0.67, p<0.0001), and the effect size was larger in studies including only patients presenting with ST-elevation myocardial infarction (STEMI) (OR 0.42, 95% CI 0.24-0.72, p=0.001). The meta-regression showed a significant relationship between the benefit of radial access and the proportion of STEMI patients (p=0.031) in each of the included studies. CONCLUSIONS: Transradial intervention is associated with a reduction in the incidence of AKI after PCI, as compared to the femoral access, and this benefit is more evident in STEMI patients. These findings warrant further confirmation in randomized controlled trials.

Coronary spasm and myocardial bridging: an elusive pathophysiological mechanism leading to apical ballooning syndrome?

Apical ballooning syndrome or Takotsubo-like cardiomyopathy is an acute syndrome characterized by normal or near-normal coronary arteries, regional wall motion abnormalities that extend beyond a single coronary vascular bed and, often, a precipitating stressor. We observed a case of an elderly lady with Takotsubo-like left ventricular dysfunction in whom both left anterior descending artery and diagonal branch coronary artery reversible spasm and myocardial bridging were demonstrated at the time of acute cardiac catheterization. It is a common observation that a combination of multiple pathophysiological mechanisms may produce a clinically similar picture. We believe that reversible, yet extreme, spasticity elicited at the level of myocardial bridging and involving a territory beyond a single coronary branch may explain in this case a functional phenomenon, namely the Takotsubo-shaped dysfunction of the left ventricle, which is more commonly observed in women with totally normal coronary arteries after exaggerated sympathetic stimulation.

Isolated double orifice mitral valve in a young asymptomatic woman.

: Double orifice mitral valve (DOMV) is a rare congenital malformation of the mitral apparatus frequently associated with other congenital malformations of the heart, whereas the isolated form is rare. The prevalence is about 1% of congenital heart disease; valve stenosis and regurgitation are common findings. Echocardiography represents the best method to diagnose DOMV, providing both anatomical and functional data. We report a case of a young woman presenting with an isolated DOMV, in the absence of stenosis and significant regurgitation. The dysmorphic valve has been evaluated with both two-dimensional and three-dimensional echocardiography, providing impressive and detailed images of the peculiar anatomical configuration of the valve.

The Diagnostic Challenge of Dipyridamole-atropine Stress Echocardiography in a Patient with Myocardial Bridge.

A 60-year-old male patient was submitted to dipyridamole-atropine stress echocardiography (DSE) for chest pain during exertion. At rest, no electrocardiographic (ECG) and transthoracic echocardiographic (TTE) abnormalities were observed. After dipyridamole infusion, the patient complained a mild chest discomfort, without ECG changes and TTE wall-motion abnormalities. Subsequently, worsening of the anginal symptoms combined with descending ST-depression and T-negative waves occurred after atropine and unexpectedly, aminophylline administration. Coronary angiography was performed showing a myocardial bridge (MB) of the left anterior descending artery. The occurrence, during DSE, of worsening ischemic abnormalities after atropine and aminophylline administration may be a particular diagnostic feature of MB.

Cardiovascular outcomes and conventional risk factors in non-diabetic adult patients with GH deficiency: A long-term retrospective cohort study.

PURPOSE: To investigate the association between cardiovascular (CV) risk factors and cumulative CV events in patients with growth hormone deficiency (GHD) receiving GH replacement therapy (GHRT). METHODS: 53 non-diabetic adult GHD patients, aged 45.4±14.3years, 31 females, with a median follow up of 140months, were divided into two groups based on the presence (group A) or absence (group B) of systemic hypertension. Tertiles of age and LDL-cholesterol were considered as further potential prognosticators. Cumulative CV event rates were recorded and analyzed by Kaplan-Mayer method. Differences between patients with and without events were also evaluated. RESULTS: Seventeen patients (32%) entered the group A and 36 (68%) the group B. A composite of fatal and non-fatal CV events occurred in 22.6% of patients, 47.1% in group A and 11% in group B (p=0.01), CV deaths in 3 patients (5.7%; annual death rate 0.49%), 2 of whom were in group A. At Kaplan-Mayer analysis, hypertension and age>55years were major prognosticators. The odds ratio was 7.1 (95% CI: 1.74-29.12, p<0.003) and 6.2 (95% CI: 1.54-25.04, p<0.006), respectively. LDL-cholesterol showed borderline statistical significance. Patients with CV events also had high prevalence of left ventricular hypertrophy, left atrial enlargement and subclinical systolic dysfunction. CONCLUSIONS: In this study, outcomes were mainly related to hypertension and age (partially to LDL-cholesterol), confirming that management of GHD patients must be inclusive of treatment of conventional risk factors, being as important as GHRT. Optimal blood pressure control is crucial when a target organ damage is present and in patients older than 55years.
