    Abstract: Stent implantation through the stent-strut of a previously implanted self-expandable stent in the superficial femoral artery (SFA) is not usually performed because the additional stent cannot dilate sufficiently. The key point to achieve sufficient expansion of an additional stent is to break the stent-strut of the previously implanted stent. However, there is no report of how to break the stent-strut. Case summary A 72-year-old man was admitted to our hospital with acute rest pain and coldness of his left leg; he was diagnosed with acute limb ischaemia. The angiogram demonstrated a fractured stent as well as stent occlusion in the left distal SFA. The guidewire could pass only through the stent-strut because of stent fracture. Fortunately, balloon angioplasty through the stent-strut and thrombolysis achieved successful revascularization. Thereafter, an additional stent was implanted in an attempt to manage the fractured and deformed stent. To obtain sufficient expansion of the additional stent, an experimental study to examine the balloon diameter and pressure to break the stent-strut was performed. Based on the results of the experiment, the stent-strut was successfully broken, and the additional stent was expanded through the stent-strut on the second intervention. Discussion If an additional self-expandable stent is deployed through the stent-strut directly, it would not be sufficiently dilated. The key point in such a case is to break the stent-strut of the previously implanted stent by balloon inflation before deployment of the additional stent. The experimental study examined the balloon diameter and pressure that can break the stent-strut. This information would be useful when we implant an additional stent through a stent-strut.

    Abstract: The use of transvenous pacing leads is associated with the risk of developing tricuspid valve (TV) dysfunction. This develops through several mechanisms including the failure of leaflet coaptation or direct damage to the TV or to its sub-valvular apparatus and can result in significant tricuspid regurgitation (TR). Multiple approaches to pacemaker implantation after transvenous lead extraction (TLE) or surgical TV repair have been described. Placement of pacing leads across the TV is generally avoided in such circumstances. Case summary A 66-year-old woman presented with a year-long history of exertional dyspnoea, peripheral oedema, and postural neck pulsations. Her medical history included a dual-chamber pacemaker implantation for sinus node dysfunction 14 years ago. Echocardiography revealed severe lead-related TR. Her case was discussed in our multi-disciplinary team meeting. A decision was made to perform a TLE and implant a leadless pacemaker in an attempt to avoid open-heart surgery if possible. This was reserved as an option in the event of persistent severe TR. Transvenous extraction of the right ventricular lead was performed. The atrial lead was preserved and connected to and AAI device. A Micra AV was implanted allowing for atrioventricular (AV) synchronous pacing. Discussion We present the first case of successful implementation of AV sequential pacing using a dual-pacemaker approach involving the use of an AAI pacemaker and a Micra AV device. This was performed after TLE for severe lead-related TR.

    Abstract: Dynamic intraventricular obstruction after transcatheter aortic valve implantation (TAVI) has been previously reported. There is a risk of haemodynamic collapse in the case of left ventricular outflow tract (LVOT) obstruction due to systolic anterior motion (SAM) of the mitral valve. Case summary An 83-year-old woman with aortic stenosis (AS) was referred to our hospital for TAVI. Transthoracic echocardiography revealed a severely calcified aortic valve with a peak velocity of 6.3 m/s across the valve. Acceleration of blood flow (peak velocity 2.6 m/s) at the LVOT due to a septal bulge was also seen. Transfemoral TAVI was performed, and a 29 mm Evolut PRO was implanted under general anaesthesia. After the implantation, a complete atrioventricular block with junctional rhythm developed, and refractory hypotension occurred immediately. Transoesophageal echocardiography revealed LVOT obstruction due to SAM of the mitral valve associated with severe mitral regurgitation (MR), which was not observed preoperatively. Fluid infusion and catecholamine administration were not effective. However, after performing temporary pacing from the right ventricular (RV) apex, the LVOT obstruction and severe MR improved. Her haemodynamics stabilized, and we could complete the procedure. A dual-chamber permanent pacemaker with beta-blocker administration as a longer-term treatment further improved the LVOT obstruction. The patient was finally discharged to a rehabilitation hospital. Discussion Alertness and recognition of potential LVOT obstruction after TAVI are important. Pacing from the RV apex, as well as dual-chamber pacing, comprise a less invasive and feasible therapeutic option in such cases.

    Abstract: Transcatheter aortic valve implantation inside a previously implanted bioprosthesis is an alternative treatment for patients with degenerated surgical aortic bioprosthesis (AB) at high surgical risk. Pre-operative computed tomography (CT) scan provides essential information to the procedure planning, although in case of acute presentation it is not always feasible. Case summary A 32-year-old man with history of surgical treatment of aortic coarctation and Bio-Bentall procedure was transferred to our department in cardiogenic shock with a suspected diagnosis of acute myocarditis. A transthoracic echocardiogram (TTE) revealed a severely impaired biventricular function and AB degeneration causing severe stenosis. It was decided to undertake an urgent trans-apical valve-in-valve (ViV) procedure. Due to haemodynamic instability, a preoperative CT scan was not performed and transoesophageal echocardiography (TOE) was the main intraprocedural guiding imaging technique. Neither intraprocedural nor periprocedural complications occurred. Serial post-procedural TTE exams showed good functioning of the bioprosthesis and progressive improvement of left ventricular ejection fraction. Patient was discharged from the hospital 8 days after the intervention. Discussion A patient with cardiogenic shock due to severe degeneration of the AB was treated with urgent transapical ViV procedure. In this case, where urgent ViV technique was needed, TOE appeared to be a crucial alternative to CT scan and allowed us to perform a successful procedure.

    Abstract: Left atrial appendage occlusion devices are commonly used to prevent stroke in patients with persistent atrial fibrillation who are unable to tolerate anticoagulation. However, certain patient- and device-related characteristics increase the risk for the development of a device-related thrombus (DRT). The presence of a DRT increases the risk of stroke and should be treated. Management of DRT lacks consensus but is mostly focused on anticoagulation. In patients with large thrombi that need to be managed urgently, percutaneous extraction may be a viable option. Case summary In this report, we describe the successful management of a DRT via percutaneous thrombus extraction technology in an 81-year-old woman with a large thrombus attached to a WATCHMAN™ device. The patient initially presented with shortness of breath, and on imaging a pedunculated thrombus was detected. The thrombus was extracted using a Penumbra Lightning 12™ (Penumbra Inc., Alameda, CA, USA) catheter with a Sentinel™ (Boston Scientific, Marlborough, MA, USA) cerebral embolic protection device. The patient had no neurologic sequelae and was started on anticoagulation. Discussion Percutaneous thrombectomy can be safely performed to extract large left atrial occlusion DRT that require urgent management, without any neurologic sequelae. We believe this can be used in patients with a large DRT who would not be adequately managed with anticoagulation and in whom surgery is not feasible.

    Abstract: Tako-tsubo stress cardiomyopathy is a clinical syndrome marked by transient reduction of left ventricular function in the setting of emotional or physical stress and in the absence of obstructive coronary artery disease. We describe a case of an atypical variant of Tako-tsubo in a male patient following an elective direct current cardioversion (DCCV). Case summary A 78-year-old male whose atrial fibrillation persisted after earlier unsuccessful direct current DCCV and radiofrequency ablations presented to the emergency department for acutely worsening dyspnoea and orthopnoea 12 h following his most recent DCCV. Previously, he was known to have non-obstructive coronary artery disease. Evaluation was notable for troponin I 0.019 ng/mL (negative & lt;0.050 ng/mL), pro-brain natriuretic peptide 2321 pg/mL (reference range 0.0–900 pg/mL). There were no acute electrocardiogram abnormalities. He required bilevel positive airway pressure but was weaned off eventually to room air. Transthoracic echocardiogram revealed newly reduced left ventricular ejection fraction of 45–50%, associated with hypokinesis of the basal anteroseptal segment, as well as akinesis of mid-inferoseptal and mid-anteroseptal segments. Apical contractility was preserved. On Day 5 of hospitalization, diagnostic left heart catheterization again revealed benign coronary anatomy, and he was discharged home the following day. Discussion Only five other cases of cardioversion mediated Tako-tsubo cardiomyopathy have been reported in the literature. To our knowledge, this is the first case of DCCV-induced atypical Tako-tsubo cardiomyopathy. Although overall prognosis is favourable, some have been observed to require advanced support therapy. Given risk for life-threatening complications, patients undergoing cardioversion should be educated on symptoms of congestive cardiomyopathy.

    Abstract: Intracardiac thrombi are a complication associated with cardiomyopathies. In heart failure with reduced ejection fraction, there is a hypercoagulable state that can increase the incidence of left ventricular thrombus and result in higher risk of thromboembolism, either manifested as stroke or as peripheral thromboembolic event. Haemoconcentration following decongestion treatment may enhance blood viscosity. Case summary A 63-year-old man with known long-standing heart failure (HF) of ischaemic aetiology and not any prothrombotic risk, admitted with congestive HF and treated with aggressive decongestion treatment with intravenous loop diuretics. During his hospital stay, and following decongestion and haemoconcentration, a left ventricular (LV) intracardiac thrombus formation was detected by echocardiography, which occurred in the absence of a recent myocardial infarction or adverse LV remodelling. The patient was treated with oral anticoagulation therapy. There was a complete resolution of the thrombus on repeat transthoracic echocardiography after 4 weeks of treatment. Discussion Aggressive decongestive treatment, haemoconcentration and increased blood viscosity following HF decompensation may serve as a trigger for intracardiac thrombus formation under the appropriate prothrombotic background. Appropriate primary antithrombotic prophylaxis is an issue raised concerns and vulnerable patients need closed clinical and imaging follow-up.

    Abstract: Coronary arterial fistulae are rare yet have been associated with hypertrophic cardiomyopathy (HCM). We present a patient who was found to have a left circumflex (LCx) to left ventricular (LV) fistula in combination with apical HCM. Case summary  A 72-year-old female presented with syncope after exercise. She sustained facial injuries including fracture of her nasal bones. There were no previous episodes, no cardiac history, and she denied chest pain or anginal symptoms. Electrocardiogram showed sinus rhythm with T-wave inversion throughout the chest leads. Echocardiography suggested apical HCM with hypertrophy of the LV apex but good systolic function. This was confirmed on cardiac magnetic resonance imaging with a characteristically spade-shaped LV cavity. Coronary angiography demonstrated a distal LCx to LV fistula from the apical hypertrophy but no coronary artery disease. She was started on beta-blockers and has had no further episodes, remaining well. Discussion  Coronary fistulae are present in 0.002% of the population but clinical outcomes are poorly understood. The majority are asymptomatic but anginal chest pains can occur through the ‘coronary steal’ phenomenon. Apical HCM is a subtype of HCM characterized by spade-shaped LV cavity obliteration. It is unclear whether the association between fistulae and HCM occur because of the increased vascularization and fibrosis associated with HCM or whether congenital malformation leads to hypertrophy. Both can produce a constellation of cardiac symptoms. Our patient has the previously unreported combination of apical HCM and an LCx fistula; two rarer subtypes of rare conditions appearing together.

    Abstract: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited condition, with approximately 60% of patients carrying a possibly disease-causing genetic variant. Known desmosomal genes account for about 50% of those variants. We herein report a family with ARVC in which a pathogenic desmosomal variant was missed because of the initial genetic testing method. Case summary A 54-year-old man diagnosed with ARVC underwent genetic cascade screening for a heterozygous titin variant (TTN: c.26542C & gt;T), detected in his phenotypically affected sister. He did not harbour this TTN variant. Moreover, reclassification of this variant based on the American College of Medical Genetics (ACMG) 2015 criteria showed it to be likely benign. Upon genetic re-screening with a dedicated cardiomyopathy panel a heterozygous missense variant in desmoglein-2 (DSG2: c.152G & gt;C) was found. His sister’s DNA was re-analysed and the same DSG2 variant was detected, and classified as LP (likely pathogenic) by current literature. Discussion The initial genetic screening tool used in the patient’s sister (whole-exome sequencing, WES) failed to detect the likely causative desmosomal variant in our family. While WES represents a good tool in searching for novel genes in Trio Analysis, it has a low DNA coverage in important regions (mean 10×) of known ARVC-associated genes. We therefore propose using smaller panels with better coverage in the clinical setting, such as Trusight-cardio (mean DNA coverage 100–300×) as an initial genetic screening method.

    Abstract: Corona pandemic has infected over 277 million people and has claimed more than 5.4 million lives with recovery of 249 million globally by early 2022. The global case fatality rate ranged from 6-7% in United States, Switzerland, Ireland, 12-14% in Sweden, Spain, Netherlands, United Kingdom, Italy, and 15-16% in France and Belgium among hospitalized and non-hospitalized COVID-19 patients, the prevalence of underlying cardiovascular diseases was 9%. The prevalence of cardiovascular diseases among hospitalized COVID-19 patients and those requiring intensive care unit admission were 23% and 29% respectively. The virus continues to evolve into new formats latest being Delta and Omicron variants. In a multicenter study of 8910 COVID-19 patients from 169 hospitals in Asia, Europe and North America, presence of pre-existing coronary artery disease, chronic heart failure and cardiac arrhythmia was associated with increased mortality of 10.2%, 15.3% and 11.5% respectively, compared with 5-6% mortality in those without the above co-morbidities. The systemic inflammation caused by SARS-CoV-2 could lead to a wide spectrum of cardiovascular complications including acute cardiac injury, acute coronary syndrome, coronary artery dissection, acute myocarditis, cardiomyopathy, chronic heart failure, cardiac arrhythmia, pulmonary embolism, cardiogenic shock, circulatory failure or even cardiac arrest.
