RESUMEN
BACKGROUND: The development of heart failure is a turning point in the natural course of aortic stenosis (AS). Pulmonary oedema and elevated left ventricular pressure (LVP) are cardinal features of heart failure. Evaluating pulmonary oedema by lung ultrasound involves taking the upper hand with a bedside noninvasive tool that may reflect LVP. AIM: We sought to assess the correlation between sonographic pulmonary congestion, invasive LV pre-A pressure, and echocardiographic LV end-diastolic pressure (LVEDP) in symptomatic AS patients receiving transcatheter aortic valve replacement. METHODS: Forty-eight consecutive patients with severe AS and planned transcatheter aortic valve implantation (TAVI) were enrolled. LVEDP was estimated to be normal or elevated using the ASE/EACVI algorithm and transmitral Doppler indices, the E/A ratio, the E/e', and the left atrial volume index. Invasive LV pre-A pressure was used as a reference, with > 12 mm Hg defined as elevated. RESULTS: Forty-eight patients (25 women (52%), mean age 75 years, standard deviation (SD) ± 7.7 years) were enrolled in the study. We detected severe B-lines (≥ 30) in 13 (27%) patients and moderate B-lines (15-30) in 33 (68.6%) patients. The number of B-lines increased significantly with the severity of New York Heart Association (NYHA) functional classes (Fig. 1). The B-line count was 14 ± 13 in NYHA class I patients, 20 ± 20 in class II patients, and 44 ± 35 in class III patients (p < 0.05, rho = 0.384). The number of B-lines was correlated with the E/E' ratio (R = 0.664, p < 0.0001) and the proBNP level (R = 0. 882, p < 0.008). We found no significant correlation with the LVEDP or LVEF. The LVEDP correlated well with the E/E' ratio (R = 0.491, p < 0.001) but not at all with E/A, DT, or LAVI. All patients had an elevated LVEDP > 12, with a mean pressure of 26 mmHg, a minimum of 13 mmHg, and a maximum of 45 mmHg, with an SD of 7.85. CONCLUSION: Assessing lung ultrasonic B-lines is a straightforward and practical approach to identifying pulmonary oedema in AS patients. The number of B-lines correlated with the E/E' ratio and the functional status of patients but did not correlate with invasive LVEDP or LVEF. All patients had elevated LVEDP that correlated with E/E'.
RESUMEN
Double connection of partial anomalous pulmonary venous return is a very rare congenital anomaly where at least one pulmonary vein, but not all, drains into the left atrium and systemic venous circulation with subsequent left to right shunt.
RESUMEN
Mitral valve prolapse (MVP) is a primary valvular disease of the mitral valve with a prevalence of 2.4% of the general population. Valve abnormalities range from simple fibroelastic deficiency of the leaflets to diffuse myxomatous degenerative changes. MVP is a usually a benign condition. However, the scattered reports of sudden cardiac death in patients with MVP in the absence of severe mitral insufficiency or coronary artery disease suggest the existence of a malignant phenotype of MVP. We report a case of a young female who survived life-threatening arrhythmias and cardiac arrest and was found to have characteristic features of the malignant phenotype of MVP and had an implantable cardioverter defibrillator as a secondary prevention. LEARNING POINTS: Malignant MVP may be associated with life-threatening arrhythmias and sudden cardiac death.MVP is not always a benign condition, and physicians should be aware of the diagnostic criteria for malignant MVP.Echocardiography and cardiac magnetic resonance are crucial diagnostic methods to detect signs suggestive of malignant MVP.
RESUMEN
Background: Tirzepatide is a novel glucagon-like peptide 1/glucose-dependent insulinotropic peptide (GLP-1/GIP) receptor agonist. It was recently approved for diabetes control and weight reduction in non-diabetic patients. Case description: We report the first case of ketoacidosis after the use of tirzepatide in an obese non-diabetic patient, secondary to the possibility of starvation ketoacidosis and insulin resistance. Conclusion: The dual-acting GLP-1 and GIP receptor agonists, tirzepatide, can induce ketoacidosis in obese non-diabetic patients. LEARNING POINTS: The dual-acting GLP-1 and GIP receptor agonists can cause ketoacidosis in obese non-diabetic patients.Ketoacidosis induced by tirzepatide is serious, and physicians should be aware of this complication and be alert to early symptoms, check serum and urine ketone levels, and stop medication.
RESUMEN
Point of care ultrasound (POCUS) can make an expedited diagnosis, which might lead to early correct management. POCUS should be used in a systemic and integrated approach to evaluate multiple organs in patients with sepsis and septic shock. We present a rare case of sepsis due to nontyphoidal Salmonella endocarditis with splenic abscess in which a multiorgan POCUS examination led to expedited treatment.
RESUMEN
Objective: The reported hypocalcemia in postmenopausal women with osteoporosis who received Denosumab was low (0.05%-1.7% to 7.4%). The major prediction factors were vitamin D and calcium levels and renal function. The objective is to evaluate the incidence of hypocalcemia in patients with osteoporosis, normal renal function, and vitamin D who received Denosumab. Method: A retrospective analysis was conducted using the medical records (2022-2023). We looked for hypocalcemia (albumin-adjusted calcium lower than 2.2 mmol/L). Results: Two hundred one postmenopausal women diagnosed with osteoporosis and received denosumab treatment were included. All patients received vitamin D3 capsules and calcium supplementation. The mean age of the patient was 75.7 ± 7.0 years (56-91 years). Hypocalcemia was observed in 46 (23%) patients following a subcutaneous dose of Denosumab 60 mg. Median calcium was 2.25 mmol/L (minimum: 0.890 mmol/L, maximum: 2.6 mmol/L). Fourteen (30.4%) patients had severe hypocalcemia (<1.8 mmol/L) and required parenteral correction. A comparison between hypocalcemia and patients with normal calcium indicated that the significant predictor of hypocalcemia was pretreatment parathyroid hormone levels (9.9 ± 11.8vs 7.6 ± 2.56 pmol/L, respectively; P < .005). The prognostic role of parathyroid hormone for the denosumab-associated hypocalcemia was assessed using ROC curve analysis. For the cut-off value of Parathyroid hormone = 6.8 pmol/L, giving serum parathyroid measurement an AUC of 0.668 (0.599-0.737) - P = .0007; sensitivity 85%; specificity 52%. Conclusion: Hypocalcemia induced by the denosumab treatment is more prevalent than previously shown in patients with osteoporosis receiving adequate calcium and vitamin D supplements. An elevated parathyroid hormone predicts hypocalcemia related to denosumab therapy in patients with normal calcium and vitamin D levels.
RESUMEN
Coronary cameral fistula (CCF) is defined as an abnormal connection between the coronary artery and any cardiac chamber. It usually appears due to abnormal embryogenesis and represents less than 1% of the population. Most CCF cases are asymptomatic, however large CCFs may cause symptoms and complications. We present a case of a young female with symptomatic CCF suspected on echocardiography and confirmed by computed tomography coronary angiography. She was successfully treated surgically with total improvement of symptoms. LEARNING POINTS: Coronary cameral fistula (CCF) is an abnormal communication between the coronary arteries and cardiac chambers. Most fistulas are asymptomatic, however, large CCFs can cause symptoms.CCF can cause angina pectoris due to the coronary steal phenomenon, and may require surgical intervention.Coronary computed tomography angiography is a highly sensitive method for detecting coronary artery fistulas noninvasively.
RESUMEN
INTRODUCTION: Necrotizing fasciitis is a recognized rare complication of gastrostomy tube replacement, but if it occurs and is not discovered early, a lethal outcome is possible. CASE PRESENTATION: We present a woman in her 80s who was known to have chronic atrial fibrillation with ischemic heart disease. She was fed through percutaneous endoscopic gastrostomy after brain injury. Erythema was observed around the stoma of the gastrostomy tube, which was later removed, and erythema extended to the left anterior abdomen. The patient was diagnosed with cellulitis. Point-of-care ultrasound examination suspected necrotizing fasciitis and, confirmed later by computerized tomography of the abdomen. The case was managed surgically. DISCUSSION: Patients with a high clinical suspicion of necrotizing fasciitis should undergo early surgical debridement with antibiotic administration. Necrotizing fasciitis starts with a clinical picture indistinguishable from other skin infections, such as cellulitis, and imaging modalities are important for confirmation and early diagnosis. We present a case of necrotizing fasciitis after gastrostomy tube replacement for which point-of-care ultrasound played a pivotal role in confirming the diagnosis early. CONCLUSION: Point-of-care ultrasound is a useful adjunct tool for clinical evaluation and assessment in diagnosing early critically ill patients with life-threatening necrotizing infections.
RESUMEN
Mitral annulus calcification is a common incidental finding in echocardiography examination of predisposed populations. On the other hand, caseous calcification of the mitral annulus is a rare variant that challenges the physician to differentiate it from different causes of cardiac masses. We describe a case of incidentally discovered caseous calcification confirmed with CT cardiac and cardiac magnetic resonance. LEARNING POINTS: Caseous calcification of the mitral annulus is a rare condition.An important differential diagnosis is cardiac tumours and myocardial abscesses.Cardiac computed tomography and cardiac magnetic resonance imaging are important in confirming the diagnosis, and assessing the extent and location of annular calcium.
RESUMEN
Acute pulmonary thromboembolism (PTE) is considered the third most frequent acute cardiovascular syndrome behind myocardial infarction and stroke, with annual incidence rates ranging from 39 to 115 per 100,000 people and ranking high among the causes of cardiovascular mortality. High-risk PTE is characterised by haemodynamic instability and encompasses clinical manifestations such as cardiac arrest, obstructive shock and persistent hypotension. The European Society of Cardiology (ESC) recommends a reperfusion strategy with systemic thrombolytic therapy for high-risk PTE under class I, level B if there are no contraindications. Overall, unsuccessful thrombolytic therapy and recurrent PTE have been reported in 8% of patients with high-risk PTE. The guidelines recommend surgical pulmonary embolectomy if thrombolysis is contraindicated or has failed. The position of repeated thrombolytic therapy as a treatment option in patients with recurrent high-risk PTE, especially in situations with a lack of surgical expertise or resources, was not mentioned in the guidelines. We report the case of a patient who suffered a recurrent high-risk PTE and was treated with repeated thrombolytic therapy that was effective and resulted in excellent outcomes. LEARNING POINTS: Acute pulmonary thromboembolism (PTE) is a serious medical condition and widespread disease with well-recognised morbidity and mortality.Systemic thrombolytic therapy should be the first choice in patients with high-risk PTE without contraindication.Repeated thrombolytic therapy in recurrent high-risk PTE might be effective in patients with low risk of bleeding as an alternative to surgical embolectomy or catheter-directed therapy.
RESUMEN
Cardiac conduction disorder may have a wide range of aetiology and can manifest with symptomatic bradycardia and syncope. Celiac disease is a malabsorptive long-term autoimmune disorder where the small intestine is the primarily affected organ due to gluten intolerance in genetically predisposed individuals. The associations between celiac disease and cardiac pathology are uncommon. We report a case of a 50-year-old woman with a known case of celiac disease who presented with a symptomatic cardiac conduction abnormality that improved with a gluten-free diet. LEARNING POINTS: Celiac disease is a malabsorptive long-term autoimmune disorder where the small intestine is the primarily affected organ due to gluten intolerance and affects 1% of the general population.Cardiovascular pathology, including dilated cardiomyopathy, myocarditis, arrhythmias, and premature atherosclerosis, was found to be more prevalent in patients with celiac disease than in others without celiac disease.The association of celiac disease with isolated advanced atrioventricular conduction abnormality is rare and a gluten-free diet may help improve the conduction abnormality.
RESUMEN
Anomalous left coronary artery from the pulmonary artery (ALCAPA) is considered a rare congenital heart disease where the take-off of the left coronary artery abnormally originates from the pulmonary artery instead of left aortic sinus. It is associated with a high mortality rate in the first year of life and sudden death in adults if left untreated. We report an adult form of ALCAPA syndrome in a 20-year-old female who presented with anginal pain for the previous few months. Unfortunately, the patient was hesitant to have surgery at the time. LEARNING POINTS: The abnormal origin of the left coronary artery from the pulmonary artery (ALCAPA) is rare and potentially fatal coronary congenital disease, accounting for 0.5% of all congenital heart diseases; it is associated with poor outcomes if left untreated.ALCAPA is classified into infantile and adult forms. The prevalence of adult individuals with ALCAPA syndrome has significantly increased as a result of recent developments in non-invasive cardiac imaging.The prevalence of sudden mortality in childhood and the early stages of adulthood makes surgery the preferred treatment, and coronary reimplantation surgery is considered the surgical procedure of choice.
RESUMEN
Hydatid disease, also known as cystic echinococcosis, is a parasitic infection caused by the larval stage of Echinococcus granulosus. It usually invades organs such as the liver and the lungs but can affect any organ. Isolated cardiac involvement is a rare manifestation. We present a case of isolated left ventricle hydatid cyst with negative serological tests, which was treated with surgical removal and confirmed by histopathological examination. LEARNING POINTS: Isolated cardiac hydatid disease is rare and accounts for only 0.5-2% of cases among infected patients.Cardiac hydatidosis may present with a wide variety of clinical manifestations ranging from no symptoms to sudden death; palpitations may be the only complaint.Surgical excision is the treatment of choice for cardiac hydatid disease to avoid high-risk complications.
RESUMEN
According to the modified World Health Organization (WHO) classification, pregnant women with mechanical valves face a very high risk of complications (Risk Category III). Mechanical valve thrombosis is a serious complication that significantly increases during pregnancy due to multiple mechanisms. Thrombolytic therapy has recently been used as a first-line treatment for mechanical valve thrombosis during pregnancy. However, the consensus regarding the optimal treatment strategy, type, dose and route of administration was unclear. We present three cases of mechanical mitral valve thrombosis during pregnancy treated successfully with repeated doses of ultraslow infusion of low-dose tissue-type plasminogen activator (t-PA) alteplase. We also present a review of the literature on this subject. LEARNING POINTS: Pregnancy in women with mechanical heart valves significantly increases the risk of maternal mortality or severe morbidity.Non-compliance with anticoagulant therapy and/or less frequent monitoring of therapeutic levels during pregnancy can result in serious complications such as valve thrombosis and thromboembolism.Thrombolytic therapy with low-dose tissue-type plasminogen activator can be an attractive alternative to surgical valve replacement and medical treatment in appropriately selected pregnant women with thrombosis of a mechanical valve.
RESUMEN
According to the modified World Health Organization (WHO) classification, mechanical valves pose a high maternal risk and complications for pregnant women with heart disease. Left atrial appendage aneurysm (LAAA) is a rare condition that can manifest clinically in several ways or remain silent for a long time and can be either congenital or acquired. We present the case of a pregnant woman who had a LAAA discovered several years after her last mitral valve replacement. LEARNING POINTS: Left atrial appendage aneurysm is a rare entity and, in most cases, is congenital due to poor myocardial contractility of dysplastic pectinate muscles.Clinical manifestations range from an asymptomatic course with an incidental finding on echocardiography up to serious sequelae such as cardioembolic manifestations.The treatment approach includes a conservative strategy using anticoagulation and a surgical strategy with aneurysmectomy.
RESUMEN
Use of antipsychotic drugs has been associated with increased risk of venous thromboembolism in several observational studies with unclear mechanism. We present a case of a patient who experienced a significant event of venous thromboembolism after a few months exposure to atypical antipsychotic drug for his bipolar mood disorders.
RESUMEN
Transcatheter aortic valve replacement (TAVR) is an alternative treatment for selected patients with severe aortic valve stenosis who are at high risk for conventional surgery. Critical stenosis of left main coronary artery as a late complication after TAVR is quite rare.
RESUMEN
Bradyarrhymias can result in low cardiac output state despite having a normal left ventricular ejection fraction and stroke volume. Because cardiac output is defined as the product of heart rate and stroke volume, a low cardiac output state caused by bradyarrhythmias may result in type I cardiorenal syndrome.
RESUMEN
Hypotension in patients with heart failure is much more frequent in daily clinical practice than the 10-15% reported in clinical trials. In patients with heart failure with reduced ejection fraction (HFrEF), hypotension frequently limits the initiation and up-titration of guideline-directed medical therapy (GDMT). Midodrine is a peripheral alpha-1 agonist and a vasopressor anti-hypotensive agent approved for the treatment of orthostatic hypotension. We describe two cases where midodrine was prescribed in patients with HFrEF and hypotension. LEARNING POINTS: Hypotension in patients with systolic heart failure is a frequent presentation and can limit the initiation and optimization of guideline-directed medical therapy.Midodrine is a peripheral alpha-1 agonist and anti-hypotensive agent approved for the treatment of orthostatic hypotension.Midodrine may be used off-label in patients with heart failure with reduced ejection fraction (HFrEF) and symptomatic hypotension to allow optimization of medical therapy.
RESUMEN
The main ultrasound criterion for diagnosing pulmonary infarction is the presence of triangular/wedge-shaped or rounded, hypoechogenic, homogeneous, pleura-based lesions. When used in point-of-care, ultrasonography of several organs can facilitate the diagnosis of pulmonary embolism in a patient presenting with chest pain. We describe a case of chest pain which we thought was due to angina, but point-of-care ultrasonography directed us to a diagnosis of pulmonary embolism. LEARNING POINTS: Point-of-care ultrasonography can help the clinician make a rapid diagnosis in patients with acute respiratory failure.The main ultrasound criterion for diagnosing pulmonary infarction is the presence of triangular/wedge-shaped or rounded, hypoechogenic, pleura-based lesions.
