LUCAS compression device-related severe injuries in a series of patients presenting with outside hospital cardiac arrest.

This case series presents patients who presented to the hospital with an outside hospital cardiac arrest and were initially resuscitated successfully. All patients suffered fatal traumatic injuries during the resuscitation process with the common variable being the use of mechanical cardiopulmonary resuscitation (CPR) device. The goal of this case series is to describe the limitations and potential fatal side effects of CPR. We also present a review of literature with our impressions of the appropriate indications for the use of mechanical CPR. Learning objectives: 1) Recognize appropriate indications for the use of mechanical vs manual cardiopulmonary resuscitation (CPR). 2) Identify signs and symptoms of mechanical CPR-related complications.

Medical and Revascularization Management of Stable Ischemic Heart Disease: An Overview.

Stable ischemic heart disease (SIHD) affects approximately 10 million Americans with 500,000 new cases diagnosed each year. Patients with SIHD are primarily managed in the outpatient setting with aggressive cardiovascular risk factor modification via medical therapy and lifestyle changes. Currently, this approach is considered as the mainstay of treatment. The recently published ISCHEMIA trial has established the noninferiority of medical therapy in comparison to coronary revascularization in patients with moderate to severe ischemia. Percutaneous coronary intervention is currently recommended for patients with significant left main disease, large ischemic myocardial burden, and patients with severe refractory angina despite maximal medical therapy.

CAD-LT score effectively predicts risk of significant coronary artery disease in liver transplant candidates.

BACKGROUND & AIMS: Patients with cirrhosis and significant coronary artery disease (CAD) are at risk of peri-liver transplantation (LT) cardiac events. The coronary artery disease in liver transplantation (CAD-LT) score and algorithm aim to predict the risk of significant CAD in LT candidates and guide pre-LT cardiac evaluation. METHODS: Patients who underwent pre-LT evaluation at Indiana University (2010-2019) were studied retrospectively. Stress echocardiography (SE) and cardiac catheterization (CATH) reports were reviewed. CATH was performed for predefined CAD risk factors, irrespective of normal SE. Significant CAD was defined as CAD requiring percutaneous or surgical intervention. A multivariate regression model was constructed to assess risk factors. Receiver-operating curve analysis was used to compute a point-based risk score and a stratified testing algorithm. RESULTS: A total of 1,771 pre-LT patients underwent cardiac evaluation, including results from 1,634 SE and 1,266 CATH assessments. Risk-adjusted predictors of significant CAD at CATH were older age (adjusted odds ratio 1.05; 95% CI 1.03-1.08), male sex (1.69; 1.16-2.50), diabetes (1.57; 1.12-2.22), hypertension (1.61; 1.14-2.28), tobacco use (pack years) (1.01; 1.00-1.02), family history of CAD (1.63; 1.16-2.28), and personal history of CAD (6.55; 4.33-9.90). The CAD-LT score stratified significant CAD risk as low (≤2%), intermediate (3% to 9%), and high (≥10%). Among patients who underwent CATH, a risk-based testing algorithm (low: no testing; intermediate: non-invasive testing vs. CATH; high: CATH) would have identified 97% of all significant CAD and potentially avoided unnecessary testing (669 SE [57%] and 561 CATH [44%]). CONCLUSIONS: The CAD-LT score and algorithm (available at www.cad-lt.com) effectively stratify pre-LT risk for significant CAD. This may guide more targeted testing of candidates with fewer tests and faster time to waitlist. LAY SUMMARY: The coronary artery disease in liver transplantation (CAD-LT) score and algorithm effectively stratify patients based on their risk of significant coronary artery disease. The CAD-LT algorithm can be used to guide a more targeted cardiac evaluation prior to liver transplantation.

Long-term outcomes of sinus node modification in patients with severely symptomatic drug-refractory inappropriate sinus tachycardia: a single-center experience.

BACKGROUND: The purpose of the study was to evaluate the long-term outcomes of sinus node modification (SNM) in treating patients with severely symptomatic drug-refractory inappropriate sinus tachycardia (IST). METHODS: The study included 39 patients with symptomatic drug-refractory IST who have undergone SNM at Saint Louis University Hospital. Data was reviewed retrospectively. Recurrence of symptoms was assessed at 3-6-month follow-up intervals. RESULTS: The mean age of our cohort was 31.5 ± 11. The mean HR at diagnosis was 135 ± 25.4 beats per minute (BPM). Thirty-seven of 39 (94.8%) patients had complete resolution of symptoms. Of these 37 patients, 16 required 1 SNM, 17 patients required 2 SNM, and 4 patients required 3 SNM in order to achieve complete symptom resolution. Mean HR post-procedure was 78.6 ± 12.3 BPM. Thirteen of 39 patients required rate control medication post-procedure, all of whom were prescribed beta-blockers. Patients were followed every 3 to 6 months with a mean follow-up duration of 62.3 ± 42.9 months from the patient's last SNM procedure. Thirteen of those 37 patients (35.1%) developed intermittent symptomatic bradycardia requiring permanent pacemaker implantation. Two of the 39 patients had phrenic nerve injury, and 6 patients had post-procedure pericarditis. CONCLUSIONS: This study provides additional information to the limited dataset available in the literature and shows that SNM might provide patients with long-term symptomatic relief bearing in mind the potential increased risk for the need for permanent pacing.

Incidence and clinical outcomes of nosocomial infections in patients presenting with STEMI complicated by cardiogenic shock in the United States.

OBJECTIVES: This study addresses the incidence, trends, and impact of nosocomial infections (NI) on the outcomes of patients admitted with ST-segment elevation myocardial infarction (STEMI) and cardiogenic shock (STEMI-CS) using the United States National Inpatient Sample (NIS) database. METHODS: We analyzed data from 105,184 STEMI-CS patients using the NIS database from the years 2005-2014. NI was defined as infections of more than or equal to three days, comprising of central line-associated bloodstream infection (CLABSI), urinary tract infection (UTI), hospital-acquired pneumonia (HAP), Clostridium difficile infection (CDI), bacteremia, and skin related infections. Outcomes of the impact of NI on STEMI-CS included in-hospital mortality, length of hospital stay (LOS) and costs. Significant associations of NI in patients admitted with STEMI-CS were also identified. RESULTS: Overall, 19.1% (20,137) of patients admitted with STEMI-CS developed NI. Trends of NI have decreased from 2005-2014. The most common NI were UTI (9.2%), followed by HAP (6.8%), CLABSI (1.5%), bacteremia (1.5%), skin related infections (1.5%), and CDI (1.3%). The strongest association of developing a NI was increasing LOS (7-9 days; OR: 1.99; 95% CI: 1.75-2.26; >9 days; OR: 4.51; 95% CI: 4.04-5.04 compared to 4-6 days as reference). Increased mortality risk among patients with NI was significant, especially those with sepsis-associated NI compared to those without sepsis (OR: 2.95; 95% CI: 2.72-3.20). Patients with NI were found to be associated with significantly longer LOS and higher costs, irrespective of percutaneous mechanical circulatory support placement. CONCLUSIONS: NI were common among patients with STEMI-CS. Those who developed NI were at a greater risk of in-hospital mortality, increased LOS and costs.

Long-term prognosis and predictors of outcomes after negative stress echocardiography.

Negative stress echocardiography (NSE) is associated with low cardiovascular morbidity and overall mortality. We aimed to determine the clinical and echocardiographic predictors of overall and cardiovascular outcomes following NSE. Patients who underwent SE between 2013 and 2017 were reviewed. Patients with a history of solid organ transplant or being evaluated for transplant, history of end-stage renal or liver disease, and positive SE were excluded. NSE results were divided into negative diagnostic if patient reached target heart rate (THR) and had no wall motion abnormality (WMA) at rest or stress; negative non-diagnostic if patient had no WMA but did not reach THR or if image quality was non-diagnostic; and abnormal non-ischemic if patient had a resting WMA not worsened at stress along with a personal history of coronary artery disease (CAD). New CAD lesion at 1 year was defined as ≥ 50% stenosis on cardiac catheterization. Of 4119 patients with SE, 2575 were included. All-cause mortality rate was 1.1%/year and CAD rate was 3.1%/year. Predictors of all-cause mortality were age, male gender, history of smoking and being selected for dobutamine SE. Predictors of a new CAD lesion at 1 year were male gender, diabetes, personal history of CAD and abnormal non-ischemic SE. We identified clinical and echocardiographic characteristics in a subset of NSE patients who are at higher risk for subsequent adverse events. These characteristics should be accounted for during the clinical interpretation of SE, and patients found at increased risk for morbidity and mortality warrant continued follow-up.

Postoperative Atrial Fibrillation and Flutter in Liver Transplantation: An Important Predictor of Early and Late Morbidity and Mortality.

Postoperative atrial fibrillation/flutter (POAF) is the most common perioperative arrhythmia and may be particularly problematic after liver transplantation (LT). This study is a single-center retrospective analysis of POAF to determine its incidence following LT, to identify risk factors, to assess its impact on clinical outcomes, and to summarize management strategies. The records of all patients who underwent LT between 2010 and 2018 were reviewed. Extracted data included pre-LT demographics and cardiac evaluation, in-hospital post-LT cardiac events, early and late complications, and survival. Among 1011 patients, the incidence of post-LT POAF was 10%. Using binary logistic regression, pre-LT history of atrial fibrillation was the strongest predictor of POAF (odds ratio [OR], 6.72; 95% confidence interval [CI], 2.00-22.57; P < 0.001), followed by history of coronary artery disease (CAD; OR, 2.52; 95% CI, 1.10-5.81; P = 0.03). Cardiac stress testing abnormality and CAD on cardiac catheterization were also associated with higher risk. Median time to POAF onset after LT was 3 days with 72% of cases resolving within 48 hours. POAF patients had greater hospital length of stay, death during the LT admission, and 90-day and 1-year mortality. POAF was an independent risk factor for post-LT mortality (OR, 2.0; 95% CI, 1.3-3.0; P < 0.01). Amiodarone was administered to 73% of POAF patients with no evidence of increased serum alanine aminotransferase levels. POAF occurred in 10% of post-LT patients with early onset and rapid resolution in most affected patients. POAF patients, however, had significant morbidity and mortality, suggesting that POAF is an important marker for worse early and late post-LT outcomes.

Pre-Liver Transplant Cardiac Catheterization Is Associated With Low Rate of Myocardial Infarction and Cardiac Mortality.

BACKGROUND AND AIMS: A study at Indiana University demonstrated a reduction in myocardial infarction (MI) incidence with increased frequency of cardiac catheterization (CATH) in liver transplant (LT) candidates. A strict protocol for performing CATH based upon predefined risk factors, rather than noninvasive testing alone, was applied to a subgroup (2009-2010) from that study. CATH was followed by percutaneous coronary intervention (PCI) in cases of significant coronary artery disease (CAD; ≥50% stenosis). The current study applies this screening protocol to a larger cohort (2010-2016) to assess post-LT clinical outcomes. APPROACH AND RESULTS: Among 811 LT patients, 766 underwent stress testing (94%) and 559 underwent CATH (69%), of whom 10% had CAD requiring PCI. The sensitivity of stress echocardiography in detecting significant CAD was 37%. Predictors of PCI included increasing age, male gender, and personal history of CAD (P < 0.05 for all). Compared to patients who had no CATH, patients who underwent CATH had higher mortality (P = 0.07), and the hazard rates (HR) for mortality increased with CAD severity (normal CATH, HR, 1.35; 95% confidence interval [CI], 0.79-2.33; P = 0.298; nonobstructive CAD, HR, 1.53; 95% CI, 0.84-2.77; P = 0.161; and significant CAD, HR, 1.96; 95% CI, 0.93-4.15; P = 0.080). Post-LT outcomes were compared to the 2009-2010 subgroup from the previous study and showed similar 1-year overall mortality (8% and 6%, P = 0.48), 1-year MI incidence (<1% and <1%, P = 0.8), and MI deaths as a portion of all deaths (3% and 9%, P = 0.35). CONCLUSIONS: Stress echocardiography alone is not reliable in screening LT patients for CAD. Aggressive CAD screening with CATH is associated with low rate of MI and cardiac mortality and validates the previously published protocol when extrapolated over a larger sample and longer follow-up period.

Is plasma renin activity associated with worse outcomes in acute heart failure? A secondary analysis from the BLAST-AHF trial.

AIMS: Neurohormonal activation characterizes chronic heart failure (HF) and is a well-established therapeutic target. Neurohormonal activation may also play a key role in acute HF (AHF). We aim to describe the association between plasma renin activity (PRA) and three AHF outcomes: (i) worsening HF or death through day 5 of hospitalization; (ii) HF rehospitalization or death through day 30; and (iii) all-cause death through day 30. METHODS AND RESULTS: A secondary analysis of the BLAST-AHF trial was performed. Eligible patients had a history of HF, elevated natriuretic peptides, signs and symptoms of HF, systolic blood pressure >120 mmHg, and an estimated glomerular filtration rate between 20-75 mL/min/1.73 m2 . The primary trial was neutral, with no differential effect of study drug by PRA levels. Baseline PRA levels were grouped into tertiles. Adjusted Cox proportional hazard model determined the association of PRA levels with outcomes (α set at P < 0.05). Of 618 randomized patients, 578 (93.5%) had a baseline PRA. PRA was modestly, but significantly, associated with each outcome without adjustment [worsening HF or death through day 5: hazard ratio (HR) 1.11, 95% confidence interval (CI) 1.01-1.23, P = 0.04; HF rehospitalization or death through day 30: HR 1.13, 95% CI 1.02-1.26, P = 0.02; all-cause death through day 30: HR 1.18, 95% CI 1.02-1.37, P = 0.03]. After multivariable adjustment, PRA was only significantly associated with HF rehospitalization or death through day 30 (HR 1.15, 95% CI 1.01-1.32, P = 0.04). CONCLUSION: Baseline PRA levels are associated with increased risk for the composite of 30-day HF rehospitalization or death in patients with AHF.

The role of precise imaging with intravascular ultrasound in coronary and peripheral interventions.

Angiography remains a widely utilized imaging modality during vascular procedures. Angiography, however, has its limitations by underestimating the true vessel size, plaque morphology, presence of calcium and thrombus, plaque vulnerability, true lesion length, stent expansion and apposition, residual narrowing post intervention and the presence or absence of dissections. Intravascular ultrasound (IVUS) has emerged as an important adjunctive modality to angiography. IVUS offers precise imaging of the vessel size, plaque morphology and the presence of dissections and guides interventional procedures including stent sizing, assessing residual narrowing and stent apposition and expansion. IVUS-guided treatment has shown to yield superior outcomes when compared to angiography-only guided therapy. The cost-effectiveness of the routine use of IVUS during vascular procedures needs to be further studied.

False-positive stress echocardiograms: Predictors and prognostic relevance.

BACKGROUND: Recent studies indicate that the pretest likelihood of significant coronary artery disease (CAD) (≥50% luminal stenosis) is over-estimated and that the frequency and severity of positive stress tests have been decreasing. This suggests an increased prevalence of false-positive (FP) stress tests. The aims of this retrospective study were to investigate the predictors of FP stress echocardiography (SE) and to compare the outcomes of patients with FP results to those with true-positive (TP) results. METHODS: Patients who underwent SE between 2013 and 2017 in a tertiary-care center were reviewed. Included were patients aged ≥40years who had cardiac catheterization (CC) within 1year of the index stress test. SE was considered FP if a new or worsening wall motion abnormality was present in the absence of significant corresponding CAD. RESULTS: Of the 5100 patients with SE, 1069 satisfied inclusion criteria. A total of 305 patients had positive SE results; of which 162 (53%) were FP. Logistic regression revealed that female gender (p=0.009), the absence of diabetes (p=0.03), the absence of a personal history of CAD (p=0.004), and lower stress WMSI (p=0.03) were independently associated with FP results. Patients with FP results on SE had similar all-cause mortality to those with TP results. CONCLUSIONS: Accounting for predictors of FP findings on SE could improve the interpretation of SE results and limit the use of unnecessary CC. Furthermore, patients with FP results on SE could benefit from aggressive risk factor control and careful clinical follow-up.

Predicting Iliac Vein Compression With Computed Tomography Angiography and Venography: Correlation With Intravascular Ultrasound.

BACKGROUND: Intravascular ultrasound (IVUS) is considered the gold standard in diagnosing common iliac vein (CIV) compression. The presence of >50% surface area reduction by IVUS is considered significant compression by most operators. Thus, we evaluated the role of computed tomography angiography (CTA) and venography in diagnosing CIV compression when compared to IVUS. METHODS: All patients who underwent CTA of the pelvis with venous filling phase, IVUS, and venography within a few weeks apart to evaluate for symptomatic CIV compression from one cardiovascular practice were retrospectively reviewed. Quantitative vascular analysis was performed on all images obtained to determine (1) percent stenosis (PS) by venogram; and (2) minimal lumen area (MLA) and PS by CTA and IVUS at the compression site (using ipsilateral distal CIV as reference area). Spearman's rank correlation, paired t-tests, or signed rank tests were performed as appropriate to compare between values of MLA and PS among the three different imaging modalities. RESULTS: A total of 96 patients were included (62.5% females; mean age, 62.3 ± 14.8 years). A significant correlation was found between MLA-CTA and MLA-IVUS (Spearman's rho, 0.27; P=.01) and PS-CTA and PS-IVUS (Spearman's rho, 0.327; P<.01). A significant correlation was also found between PS-venogram and PS-IVUS (Spearman's rho, 0.471; P<.001). MLA-CTA and MLA-IVUS had a median difference of +41 mm² (95% CI, 25.0-57.5; P<.001) whereas PS-CTA and PS-IVUS were not statistically different (median difference, -5.6 mm²; 95% CI, -12.2 to 0.7). Furthermore, PS-IVUS and PS-venogram had a median difference of +15.2% (95% CI, 10.4-20.1; P<.001). CONCLUSION: PS-venogram correlates with PS-IVUS, but venogram underestimates the PS by an average of 15.2%. In contrast, PS-CTA and PS-IVUS are not statistically different despite an over-estimation of MLA by CTA when compared to IVUS. Therefore, we conclude that PS-CTA and not PS-venogram can be used to predict PS on IVUS.

Long-term outcomes with Jetstream atherectomy with or without drug coated balloons in treating femoropopliteal arteries: A single center experience (JET-SCE).

BACKGROUND: The long-term outcome of Jetstream atherectomy (JA) with or without adjunctive drug coated balloons (DCB) in a real-world setting remains unknown. We report 16-month target lesion revascularization (TLR) rates on patients treated for femoropopliteal (FP) artery disease with JA in a single center by one operator. METHODS: From 1/1/12 to 8/24/16 a total of 311 procedures were performed with atherectomy by a single operator at a single center. Of these procedures, 75 met inclusion and exclusion criteria. This report evaluates the outcomes of these 75 patients treated at index and who were followed up to 16 months. The primary endpoint of the study was clinically driven TLR. Patients were stratified by the use of DCB (vs angioplasty (PTA)) post-JA. TLR was calculated by excluding bailout stenting as TLR. Survival analysis for TLR over time was plotted. RESULTS: 75 patients (49.3% male, mean age 68.0 years, 54.7% diabetes) with de novo or restenotic FP lesions whose symptoms were classified as Rutherford category I-V were enrolled. Adjunctive PTA was performed on 50 patients (26 de novo, 13 in-stent restenosis, 3 non-stent restenosis, 8 mixed lesions) and adjunctive DCB (LUTONIX® 24, IN.PACT® 1) on 25 patients (21 de novo, 1 in-stent restenosis, 2 non-stent restenosis, 1 mixed lesion) (p = 0.0249). There was no difference in the median treated length between the adjunctive PTA (15 cm) and DCB (10 cm) groups (p = 0.0530). The estimated freedom from TLR (fTLR) was significantly higher with atherectomy and adjunctive DCB compared to atherectomy with adjunctive PTA at 12 months (94.7% vs 68.0%, p = 0.002) and 16 months (94.4% vs 54%; p = 0.002). CONCLUSIONS: In a single center cohort of JA reflecting real-world practice, JA with DCB had a superior TLR rate up to 16-month follow-up when compared to JA with PTA in treating all comers FP arterial disease.

Sudden Cardiac Arrest in a Young Patient With Severe Pectus Excavatum.

We report a case of sudden cardiac arrest in the setting of ventricular fibrillation in a previously healthy 19-year-old male. Chest imaging demonstrated severe pectus excavatum with Pectus Severity Index of 22.7. Extensive workup was unrevealing for other cardiopulmonary etiologies, including conduction and structural abnormalities. The patient was scheduled for a Ravitch procedure and was discharged on a wearable defibrillator vest for temporary protection against ventricular arrhythmias. Later, the patient underwent subcutaneous implantable cardioverter defibrillator placement. Sudden cardiac arrest as an initial presentation of pectus excavatum is a rare entity scarcely discussed in medical literature. In this patient-centered focused review, we explore this unique case and offer our management approach amid the lack of concrete guidelines.

Complete Resolution of a Large Bicuspid Aortic Valve Thrombus with Anticoagulation in Primary Antiphospholipid Syndrome.

Native aortic valve thrombosis in primary antiphospholipid syndrome (APLS) is a rare entity. We describe a 38-year-old man who presented with neurological symptoms and a cardiac murmur. Transthoracic echocardiography detected a large bicuspid aortic valve thrombus. Laboratory evaluation showed the presence of antiphospholipid antibodies. Anticoagulation was started, and serial echocardiographic studies showed complete resolution of the aortic valve vegetation after 4 months. The patient improved clinically and had no residual symptoms. This report and review of the literature suggests that vegetations in APLS can be treated successfully with conservative treatment, regardless of their size.

Recanalization of Total Occlusion of the Superficial Femoral Artery and Profunda Femoris Using the Transcollateral Approach.

Chronic total occlusions (CTOs) are seen in 30%-40% of symptomatic superficial femoral artery (SFA) disease. Despite advances in revascularization techniques, 10%-20% of these occlusions cannot be crossed. We report 1 case and review the literature on transcollateral retrograde crossing of the SFA from the profunda femoris. The procedural steps and devices (wires and crossing catheters) utilized by various operators are outlined. Based on an overview of current cases in the literature (19 cases, 21 CTOs), success rate was 95.2% with no complications reported. We conclude that transcollateral recanalization of chronically occluded SFA appears to be a viable technique when antegrade access is not feasible.

Predictors of common femoral artery access site complications in patients on oral anticoagulants and undergoing a coronary procedure.

BACKGROUND: It is unclear whether patients on oral anticoagulants (OAC) undergoing a procedure using common femoral artery access have higher adverse events when compared to patients who are not anticoagulated at the time of the procedure. METHODS: We retrospectively reviewed data from consecutive patients who underwent a cardiac procedure at a tertiary medical center. Patients were considered (group A) fully or partially anticoagulated if they had an international normalized ratio (INR) ≥1.6 on the day of the procedure or were on warfarin or new OAC within 48 h and 24 h of the procedure, respectively. The nonanticoagulated group (group B) had an INR <1.6 or had stopped their warfarin and new OAC >48 h and >24 h preprocedure, respectively. The index primary end point of the study was defined as the composite end point of major bleeding, vascular complications, or cardiovascular-related death during index hospitalization. The 30-day primary end point was defined as the occurrence of the index primary end point and up to 30 days postprocedure. RESULTS: A total of 779 patients were included in this study. Of these patients, 27 (3.5%) patients were in group A. The index primary end point was met in 11/779 (1.4%) patients. The 30-day primary composite end point was met in 18/779 (2.3%) patients. There was no difference in the primary end point at index between group A (1/27 [3.7%]) and group B (10/752 [1.3%]; P=0.3155) and no difference in the 30-day primary composite end point between group A (2/27 [7.4%]) and group B (16/752 [2.1%]; P=0.1313). Multivariable analysis showed that a low creatinine clearance (odds ratio [OR] =0.56; P=0.0200) and underweight patients (<60 kg; OR =3.94; P=0.0300) were independent predictors of the 30-day primary composite end point but not oral anticoagulation (P=0.1500). CONCLUSION: Patients on OAC did not have higher 30-day major adverse events than those who were not anticoagulated at index procedure.

Double Inferior Vena Cava and its Implications During Endovascular and Surgical Interventions: A Word of Caution.

Double inferior vena cava (DIVC) is present in 0.2%-3.0% of the general population. Its presence can be detected by computed tomographic angiography or magnetic resonance imaging. Identifying the presence of DIVC is important to define its relationship with the renal vein, its size when IVC filters are planned, the location of the left renal vein in relationship to the aorta, and for planning of IVC filter placement in the setting of deep vein thrombosis and pulmonary embolism. Finally, this entity should not be mistaken for lymphadenopathy and its course should be well understood before abdominal and pelvic/retroperitoneal surgical interventions.

Arrhythmogenic ventricular cardiomyopathy and sudden cardiac death: Left or right?

Arrhythmogenic right ventricular cardiomyopathy is a leading cause of sudden cardiac death among athletes in Italy and the Mediterranean region. Although it often involves the right ventricle causing scarring, dilation, systolic impairment with aneurysm formation, it can also involve the left ventricle or present as isolated left ventricular cardiomyopathy. Cardiac magnetic resonance imaging is considered the gold standard in confirming the diagnosis. We summarize four cases of arrhythmogenic ventricular cardiomyopathy with different presentations observed over the past 2 years.
