Development of Takotsubo cardiomyopathy following spontaneous coronary artery dissection in a patient with fibromuscular dysplasia.

New-onset Takotsubo cardiomyopathy following spontaneous coronary artery dissection (SCAD) is rare. We report a middle-aged woman without significant cardiovascular risk factors, who initially presented with non-ST-elevation myocardial infarction (NSTEMI) with angiography showing sudden 'pruning' of the coronary artery consistent with SCAD. One week later, the patient returned with recurrent NSTEMI. Repeat coronary angiogram showed no change in SCAD, but ventriculogram revealed new-onset apical ballooning beyond the SCAD-affected territory, consistent with Takotsubo cardiomyopathy. Further head-to-pelvis angiogram revealed an irregular beaded appearance of the left vertebral artery consistent with fibromuscular dysplasia. The patient was managed conservatively with aspirin, carvedilol and escitalopram with complete resolution of cardiac and mood symptoms. Our case supports an association between SCAD and Takotsubo cardiomyopathy in a potentially mutually aggravating process. Clinical vigilance is therefore required to rule out the other condition when one of the two entities is diagnosed.

[Outpatient coronary angiography and percutaneous coronary interventions before and after the COVID-19 pandemic : experience of the Versailles hospital centre]. / Coronarographie et angioplastie coronaire ambulatoire avant et après la pandémie de COVID-19 : expérience du centre hospitalier de Versailles.

BACKGROUND: Same day discharge (SDD) diagnostic coronary angiography and percutaneous coronary interventions (PCIs) are increasingly performed, and indications extend to more complex procedures and more fragile patients. We report the evolution of SDD interventional cardiology activity in our centre since 2016, particularly before and after the COVID-19 pandemic. Secondarily, we analysed the feasibility and safety of SDD PCI. MATERIALS AND METHODS: We analysed the number and percentage of SDD coronary angiograms and PCIs (elective or ad hoc), during 4 periods of 11 months each, from September 2016 to July 2024. Periods 1 and 2 took place before COVID-19, periods 3 and 4 after. We also compared the rate of complications and conversion to hospitalisation between periods 1-2 and 4. RESULTS: A total of 9587 procedures were analysed, including 1558 SDD procedures. The total number of SDD interventional cardiology procedures increased progressively over the 4 periods, from 146 SDD procedures (7.5%) in 2016-2017 to 620 (27.2%) in 2023-2024. This increase included both diagnostic coronary angiograms (respectively: 10.9%; 12.2%; 33.6% then 28.9%) and PCIs (respectively: 0.9%; 5.6%; 16.1% then 24.4%). In the immediate post-COVID-19 period, a significant increase, uncorrelated with the natural progression, was observed for SDD diagnostic coronary angiography and ad-hoc PCI. There were no deaths or serious complications, the rate of minor complications (1.1%) and conversion to conventional hospitalisation (4.5%) were low. CONCLUSION: Provided a careful patient selection and rigorous organisation, SDD coronary angiography and PCI can safely be performed. The increase in the SDD interventional procedures, favoured by organisational (COVID-19) or economic constraints, need to be amplified.

Endovascular Aortic Repair in Traumatic Descending Thoracic Aortic Transection: A Case Report.

Aortic transection, a near-complete tear through the layers of the aorta, is a critical condition often resulting from trauma such as motor vehicle collisions. The urgency of managing aortic transection underscores the critical need for effective interventions. We report the case of a male in his early 50s with no significant medical history who presented to the emergency department following a motor vehicle collision, sustaining multiple injuries including a descending thoracic aortic transection. Rapid diagnostic assessment confirmed the severity of the injury, necessitating immediate intervention. Endovascular aortic repair was successfully employed, highlighting its efficacy in managing acute aortic injuries. The patient responded well to treatment, underscoring the importance of timely intervention in improving patient outcomes. This case emphasizes the critical role of rapid diagnostic assessment and endovascular intervention in managing life-threatening thoracic aortic injuries, particularly in the acute setting.

Lipoprotein(a) in interventional cardiology: identifying patients at highest risk of recurrent cardiovascular events through early recognition - a case based review.

INTRODUCTION: Lipoprotein(a) [Lp(a)] is linked to higher risks of atherosclerotic cardiovascular disease (ASCVD). Current guideline recommendations are quite liberal on measuring Lp(a) (Class IIa, Level C), and may lead to underuse among (interventional) cardiologists. AREAS COVERED: This case-based narrative review outlines four clinical cases of patients with elevated Lp(a) to illustrate its pathophysiological impact on coronary artery disease (CAD). The expert consensus statements from the American Heart Association (AHA) and European Atherosclerosis Society (EAS) served as the basis of this review. More recent publications, from 2023 to 2024, were accessed through the MEDLINE online library. EXPERT OPINION: We highlighted the importance of routine Lp(a) measurement in identifying patients at high risk for atherosclerosis, necessitating potent risk mitigation. Measuring Lp(a) helps clinicians identify which patients are at highest residual risk, who require potent pharmacological treatment and special attention during catheter interventions. As noninvasive and advanced intravascular imaging modalities evolve, future catheterization laboratories will integrate advanced imaging, diagnostics, and treatment, facilitating tailored patient care. Knowing Lp(a) levels is crucial in this context. While Lp(a)-lowering drugs are currently investigated in clinical trials, it is of paramount importance to know Lp(a) levels and strive toward aggressive management of other modifiable risk factors in patients with elevated Lp(a) and established symptomatic CAD being diagnosed or treated in catheterization laboratories.

Return to professional football after ICD implantation in athlete with apical hypertrophic cardiomyopathy.

The risk of sports participation in elite athletes with cardiac disease with an indication for implantable cardioverter-defibrillator (ICD) therapy is largely unknown. Currently, international guidelines provide restrictive sports advice for such athletes. This case report presents a professional football player who after an episode of syncope and diagnosis of apical hypertrophic cardiomyopathy expressed a strong wish to explore the feasibility of returning to elite-level sports. After a shared decision-making and monitored stepwise graduated rehabilitation, the athlete made a full return to professional football. Our case indicates that individualised sports advice in elite athletes with cardiac disease and an ICD may be warranted.

Unveiling an insidious diagnosis and its implications for clinical practice: Individual patient data systematic review of pregnancy-associated spontaneous coronary artery dissection.

BACKGROUND: Pregnancy-Associated Spontaneous Coronary Artery Dissection (P-SCAD) is the most common cause of myocardial infarction in pregnancy and postpartum. Aim of this systematic review is to provide a descriptive picture of P-SCAD presentation, clinical course, management and outcomes. METHODS: International databases were systematically screened up to November 2023 and all published P-SCAD case reports/series identified; additionally, we gathered four original cases, establishing a new database for the derived cohort. RESULTS: 253 studies (215 case reports, 38 case series) were included for the analysis, enrolling 316 patients admitted between 1952 and 2023. Median age was 34 (SD 5) years old, 64 (20.4 %) were prepartum, 249 (79.6 %) postpartum. Most common presentation was ST-elevation myocardial infarction (72.6 %). Cardiac arrest and cardiogenic shock occurred in 18.4 % and 16.1 %, respectively. Multivessel dissection was present in 45.2 % of cases, with left anterior descending artery being most frequently affected (74.4 %). Initial therapeutic strategy was medical therapy in 54.8 % while upfront revascularization was performed in 45.2 % of cases. Excluding autoptic studies, mortality rate was 4.1 %, without significant differences between pre and postpartum SCAD (p-value 0.6) or according to initial therapeutic approach (p-value 0.5). Recurrences after index event were registered in 74 patients (23.4 %), being more common after medical treatment than in case of immediate revascularization (30.8 versus 18.3 %, p-value 0.02). CONCLUSIONS: P-SCAD is a complex clinical scenario: timely diagnosis is difficult, therapeutic management not well-defined, rate of recurrences not negligible. Additional observational studies and dedicated registries are necessary to enhance the management of this rare but severe condition.

Missed opportunity in acute coronary syndrome.

A man in late adolescence of Asian descent was admitted with cardiac-sounding chest pain and a history of flu-like symptoms a week prior to presentation with negative screening for the SARS-CoV-2 virus. His ECG showed lateral T-wave changes and pre-excitation pattern suggestive of an accessory pathway. High-sensitivity troponin T peak was significantly elevated to 2550 ng/L (normal reference range 0-11). He was initially treated for a suspected perimyocarditis. Transthoracic echocardiography revealed moderate left ventricular systolic dysfunction with regional wall motion abnormalities suggestive of coronary artery disease. Cardiac magnetic resonance imaging showed subendocardial delayed gadolinium enhancement with ischaemia and viability in the left circumflex (LCx) territory. He was then sent for a CT coronary angiogram for a suspected spontaneous coronary artery dissection, and subsequently, he discussed with our team and accepted for immediate transfer. He underwent coronary angiography and intravascular ultrasound-guided percutaneous coronary intervention to his LCx artery with a drug-coated balloon. Following that, and after a discussion with the electrophysiology team, he had an attempt at ablating his accessory pathway with partial success. He was discharged home in a stable condition.

Transvenous closure of patent ductus arteriosus with Nit-Occlud® PDA occlusion system in 13 dogs weighing less than 3 kg.

INTRODUCTION: Successful closure of patent ductus arteriosus (PDA) can be obtained with surgical ligation or with occlusion via minimally invasive per-catheter techniques. This study was performed to assess feasibility and effectiveness of transjugular PDA occlusion in dogs weighing < 3 kg with a device called Nit-Occlud® PDA. ANIMALS: Thirteen client-owned dogs. MATERIALS AND METHODS: This was a retrospective study. Clinical records of dogs that underwent PDA occlusion with a Nit-Occlud® PDA were reviewed. Data collection included patients' signalment, clinical findings, pre- and post-procedure echocardiographic measurements, device size, procedure time and clinical outcome. RESULTS: The median age of these patients was six months (2.5-38.0 months), with a mean body weight of 2.44 ± 0.43 kg. The mean minimal ductal diameter (MDD) was 1.82 ± 0.43 mm, while the mean ampulla diameter (AD) was 5.51 ± 1.89 mm. Duct closure was successful in 12 cases. Minimal or no residual shunt was observed on echocardiography prior to device release. In one dog, the device was not released owing to unsatisfactory occlusion, prompting an alternative occlusion method. Follow-up echocardiographic examinations showed complete ductal closure and reversed cardiac remodelling in all cases where the device was successfully released. DISCUSSION: The Nit-Occlud® is deployed through a delivery system with an outer diameter of 4 F or 5 F, which makes this solution particularly attractive in patients where vascular access is challenging or unfeasible due to the small size of their vessels. CONCLUSIONS: The Nit-Occlud® PDA appears a feasible and effective occlusion system in small patients weighing <3 kg.

Unexpected Grave's-induced acute myocardial infarction in a young female, a literature review based on a case report.

INTRODUCTION: Myocardial ischemia can occur due to several causes, which result in an imbalance between the supply and demand of oxygen to cardiac muscles. One potential reason for this condition is the overwork of the heart due to hyperstimulated thyroid function. CASE PRESENTATION: The patient was a 36-year-old woman who presented with left-sided chest pain, dyspnea, palpitation, and tremor. The initial evaluation showed evidence of myocardial ischemia (positive high-sensitivity troponin) caused by a hyperactive thyroid gland. The treatment for myocardial infarction, along with anti-thyroid medications, improved the patient's condition and subsided the symptoms. The coronary angiography revealed no pathologic finding, and the hypokinetic left ventricle, observed in the first echocardiogram, was resolved. The patient was discharged with an excellent clinical condition, and after the 4-month taking of a calcium channel blocker and tapering carbimazole, the thyroid function became normal, and her symptoms resolved completely. CONCLUSION: Patients without evident risk factors for ischemic heart disease, such as non-diabetic, nonsmoker, and young individuals who presented with acute coronary syndrome, should be evaluated for a potential background reason for the imbalance between the oxygen demand and supply of the myocardium. The presence of palpitation, weight loss, tremors, insomnia, and anxiousness, along with ischemic signs, should make the physician think about the probability of the hyperthyroid-induced cardiovascular disorder. CLINICAL KEY POINT: The initial presentation of hyperthyroidism might be accompanied by severe cardiac symptoms. When the demographic features are not aligned with usual ischemic heart disease, other probable symptoms and signs should be investigated, and thyroid function should be checked. The control of thyroid hyperactivity would result in the resolution of both cardiac and non-cardiac symptoms.

Spanish cardiac catheterization and coronary intervention registry. 33rd official report of the Interventional Cardiology Association of the Spanish Society of Cardiology (1990-2023).

Introduction and objectives This article presents the 2023 activity report of the Interventional Cardiology Association of the Spanish Society of Cardiology (ACI-SEC). Methods All interventional cardiology laboratories in Spain were invited to participate in an online survey. Data analysis was carried out by an external company and subsequently reviewed and presented by the members of the ACI-SEC board. Results A total of 119 hospitals participated. The number of diagnostic studies decreased by 1.8%, while the number of percutaneous coronary interventions (PCI) showed a slight increase. There was a reduction in the number of stents used and an increase in the use of drug-coated balloons. The use of intracoronary diagnostic techniques remained stable. For the first time, data on PCI guided by intracoronary imaging was reported, showing a 10% usage rate in Spain. Techniques for plaque modification continued to grow. Primary PCI increased, becoming the predominant treatment for myocardial infarction (97%). Noncoronary structural procedures continued their upward trend. Notably, the number of left atrial appendage closures, patent foramen ovale closures, and tricuspid valve interventions grew in 2023. There was also a significant increase in interventions for acute pulmonary embolism. Conclusions The 2023 Spanish cardiac catheterization and coronary intervention registry indicates a stabilization in coronary interventions, together with an increase in complexity. There was consistent growth in procedures for both valvular and nonvalvular structural heart diseases.

Off-label uses of the Amplatzer Piccolo Occluder in children with congenital and acquired heart diseases.

Aim: The Amplatzer Piccolo Occluder (APO) is approved for patent ductus arteriosus (PDA) occlusion in infants weighing >700 g but could offer versatility to treat other lesions.Methods: Retrospective review of children in whom APO was utilized for defects other than PDA between January 2022 and June 2023.Results: The APO was used in nine patients; three for ventricular septal defects, four with coronary fistulas, one for a ventricular pseudoaneurysm and one where APO deployed within a fenestration of a previously placed Amplatzer Septal Occluder. All nine patients had successful occlusions without complications.Conclusion: The APO is a versatile device that can be used to treat various small diameter lesions in children besides the PDA for which it is currently approved for.

[Coronary calcified and resistant lesions angioplasty in the outpatient, myth or reality ?] / Lésions coronaires calcifiées et résistantes en ambulatoire, mythe ou réalité ?

Progress in coronary angioplasty has enabled outpatients treatment with rates of immediate complications below 1%. This shows a clear improvement in patient's comfort and it represents an important medical and economic gain. Considering the demographic evolution of the population, there is an increasing number of calcified coronary lesions which represent, according to the series, up to a quarter of angioplasties. However, their care is more delicate with a greater risk of complications and procedural failure. In fact, with the difficulties of crossing and with the vascular intrusions related to pre-dilation or sub-dilation stent deployment, the complication risk increases by almost 10% in these cases of angioplasties. Similarly, the death rate at 30 days goes from 4.7% in angioplasty in general up to 24.4% in calcified lesions. Several devices for atherectomy and plaque preparation have been developed in order to better overcome the lesions and better prepare the stent installation at the cost of a risk of complications between 2 and 10%. The three most frequent complications are dissection (1.8 to 7%), slow/no-flow (0.1 to 3%) and coronary perforation (0.2 to 4%). Nevertheless, despite this procedural increased risk, ambulatory angioplasty of calcified complex lesions can become a reality subject to 4-6 hours monitoring in a specialized unit with dedicated protocols.

Persistent left cranial vena cava and right cranial vena cava aplasia in a French bulldog and a Cavalier King Charles spaniel with severe pulmonic stenosis.

One French bulldog and one Cavalier King Charles spaniel were referred for pulmonary balloon valvuloplasty (PBV) after being diagnosed with severe pulmonic stenosis. In both patients, a dilated coronary sinus was noted on transthoracic echocardiography, suggesting persistent left cranial vena cava. Despite complete preoperative workup being performed, persistent left cranial vena cava with right cranial vena cava aplasia was not identified until after right jugular catheterization. This case study highlights vascular anomalies that hinder traditional approaches to PBV and diagnostic considerations for preoperative workup as recognition of these venous anomalies would have changed the approach to catheterization for PBV, minimizing the risk for complications, saving resources, and decreasing anesthetic time in these patients.

Techniques for Identifying a Patent Foramen Ovale: Transthoracic Echocardiography, Transesophageal Echocardiography, Transcranial Doppler, Right Heart Catheterization.

Noninvasive and invasive imaging modalities play important roles for the detection of patent foramen ovale (PFO). Transthoracic echocardiography or transcranial Doppler bubble study can be used for initial noninvasive PFO screening. For diagnostic confirmation, transesophageal echocardiography bubble study can be utilized, a semiinvasive confirmatory test that can directly visualize a PFO. In selective cases when the diagnosis is in doubt, PFO can be accurately diagnosed invasively with right heart catheterization. Understanding the advantages and limitations of each diagnostic option will help clinicians choose the appropriate test for patients presenting with a PFO-associated condition who may benefit from percutaneous device closure.

Familial catamenial coronary spasms.

Coronary artery spasms represent important causes of myocardial ischaemia and infarction in patients with non-obstructive coronary artery disease. They are notably seen in younger people and occur almost equally in men and women. Besides traditional risk factors (ie, smoking), female hormones might also play a role.We report of two young sisters who presented with myocardial infarction caused by catamenial coronary spasms (CS), that is, during menstruation. In one of these women, this resulted in heart failure with a severely reduced ejection fraction and ultimately a heart transplant because of intractable ventricular arrhythmias.CS might result from changing hormone levels (especially oestrogen) during menstruation. Increased awareness of the occurrence of catamenial CS is essential for diagnosis and consequent treatment with coronary vasodilators and/or specific oestrogen/progesterone regimens.

Aberrant origin of the left coronary artery from the right coronary sinus with a common orifice with the right coronary artery.

In patients with anomalous origin of the left main coronary artery, accurate classification is essential for effective management. Despite surgical refusal, successful stenting and medication can lead to favorable outcomes. Regular monitoring ensures ongoing cardiac health. Abstract: Coronary artery anomalies, including anomalous origin of the left main coronary artery from the right sinus of Valsalva, are rare occurrences with varying clinical significance. Accurate classification of these anomalies is crucial for determining their implications and guiding management. A 50-year-old man presented with chest pain and was diagnosed with an anomalous origin of the left main coronary artery. Despite refusing surgery, successful stenting and medication led to a favorable outcome. Regular monitoring is scheduled. Accurate classification of coronary anomalies, such as the left main coronary artery anomaly described, is vital for effective management. Even when surgical intervention is declined, alternative treatments, such as stenting, can be successful. Regular monitoring ensures ongoing cardiac health.
