Evaluation of Cognitive Functions in Patients with Acute Coronary Syndrome Undergoing Percutaneous Coronary Intervention: A Prospective Pilot Study.

PURPOSE: It is not clear whether cognitive functions are impaired in young patients with acute coronary syndrome (ACS). This study aims to detect whether or not there is cognitive impairment and cerebral changes in young patients with ACS undergoing percutaneous coronary intervention (PCI). PATIENTS AND METHODS: All 50 patients with ACS who were treated with primary PCI were eligible for this prospective study. All participants had normal cognitive function before ACS. Brain magnetic resonance imaging (MRI) was performed to quantify changes in brain white and gray matter. Cognitive functions (CFs) were evaluated by seven cognitive tests. Patients were categorized by MRI findings and test scores were compared from the first day to after the first month. RESULTS: We determined 25 patients with impaired CFs on the first day. After the first month, we identified 18 patients with transient impaired CFs. No structural difference was observed between impaired CF and normal CF. While 25 patients had a score of 1 according to Fazekas, 10 patients had a score of 1 according to MTLA. While the mean Stroop test completion time and Stroop test error rate scores were significantly higher on the first day than after the first month in the Fazekas+ group (p = 0.003, p < 0.001, respectively), other cognitive test scores-except clock drawing test, digital span forwards, and backwards-were significantly lower on the first day compared to after the first month in the Fazekas+ group (p < 0.05). CONCLUSIONS: Patients with ACS have transient impairment in cognitive functions. Acute coronary syndrome is not associated with structural changes in the brain.

Effects of Atrioventricular Blocks in Acute Coronary Syndrome: Long-Term Follow-Up.

Objectives: Arrhythmias are the common, potentially lethal, and treatable complication of acute coronary syndrome (ACS). Arrhythmic findings of ischemic cardiac events are well-known, but long-term results have not been scrutinized. In the study, we aimed to analyze the long-term findings of the atrioventricular block (AVB) in ACS patients. Methods: This is a single-center and retrospective study of patients admitted with ACS and AVB. The primary endpoint has combined the outcome of major adverse cardiovascular events and mortality. Results: Seventy-six (89.4%) patients had 3rd-degree AVB. Fifty (58.8%) patients are needed for temporary ventricular pacing and 4 (4.7%) for a permanent pacemaker. Although no cardiac death occurred during the 5-year follow-up period, the in-hospital mortality ratio was 30.6%. Patients with older age and lower systolic blood pressure (SBP) levels had higher mortality rates (respectively, odds ratio [OR] 1.088, [p=0.003], OR 0.912, [p<0.001]). Even in ST-segment elevation myocardial infarction and complete AVB subgroup analyses, mortality rates were associated with SBP and age (respectively, OR: 0.917, [p<0.001], OR: 1.107 [p=0.002]), (respectively, OR: 0.917 [p<0.001], OR: 1.087 [p=0.004]). Conclusion: The study results are associated with a better long-term overall prognosis in patients with ACS with AVB, but lower SBP and older in-hospital follow-up are associated with poor prognosis.

Clinical Presentation, Electrocardiographic Findings, and Factors Related to the Hospitalization In Mad-Honey Intoxication.

Objectives: Mad-honey intoxication (MHI) often presents with all kinds of bradyarrhythmias. Despite numerous publications focused on clinical findings, we aim to evaluate poor prognostic implications, ischemia likely electrocardiography (ECG) changes, and detailed ECG findings of MHI in the largest series. Methods: This is a retrospective single-center study of 117 MHI patients admitted to emergency service. Results: The study had 26 (22.2%) females (median 52.5 years) and 91 (77.8%) males (median 51.0 years). Fifty-six (47.9%) patients had ischemia likely changes on ECG. Multivariate model demonstrated that beta-blocker usage (odds ratio (OR): 52.871; 95% confidence interval (CI): 3.618-772.554 (p=0.004)), atrioventricular junctional rhythm (AVJR) (OR: 5.319; 95%CI: 1.090-25.949 (p=0.039)), and quantity of mad-honey consumption (OR: 1.035; 95% CI: 1.008-1.063 (p=0.011)) are predictors of hospitalization. ROC curve analysis showed cutoff value of mad-honey consumption quantity 24.79 g had 57% sensitivity and 68% specificity for predicting hospitalization (AUC: 0.7, 95% CI: 0.55-0.816, p=0.027). In addition, all hospitalized cases were male. Conclusion: Our study has shown that male gender, AVJR, the quantity of mad-honey consumption, and beta-blocker usage are high-risk criteria for hospitalization in MHI patients. Furthermore, ischemia likely ECG changes is often observed with MHI even independently from hypotension or bradycardia.

Three-dimensional echocardiographic assessment of Chiari's network relationship with the left ventricular false tendon.

BACKGROUND: Left ventricular false tendon (LVFT) is a fibromuscular band crossing the left ventricular cavity. And Chiari's network (CN) is a highly mobile, mesh-like, echogenic structure in right atrium. In this study, we aimed to evaluate the coexistence of LVFT in patients with CN. CN patients were examined with live/real-time three-dimensional transthoracic echocardiography (TTE) for visualization of LVFT. RESULTS: This is a single-center prospective study of 49 patients with CN. In literature studies, the average ratios of LVFT were 22% in the normal population. In our study, an increased ratio of LVFT (n = 31, 63.3%) was found in CN patients evaluated with a three-dimensional TTE (63.3% versus 22%) (p = 0.01). The interatrial septal aneurysm was found in 31 (63.3%) patients with CN. And, the positive contrast echocardiography examination was determined in 22 (61.1%) patients with CN. CONCLUSIONS: Our study reveals that CN is associated with LVFT and is also associated with cardiac anomalies like an interatrial septal aneurysm, and atrial septal defect. And LVFT can be evaluated better with three-dimensional TTE than with traditional two-dimensional TTE. Patients with CN should be evaluated more carefully by three-dimensional echocardiography as they can be in synergy in terms of the cardiac pathologies they accompany.

In-Hospital Bleeding in Elderly Patients With Acute Coronary Syndrome: Are Potent Antiplatelet Agents Safe?

Despite implementation of new interventional techniques and therapeutic advances, elderly patients with acute coronary syndrome (ACS) continue to be susceptible to in-hospital bleeding compared with younger ones. Thus, we investigated the incidence of in-hospital bleeding events and associated risk factors in elderly (≥ 75°years) ACS patients. We also wanted to define the bleeding sites, characteristics, and associated mortality. Bleeding Academic Research Consortium (BARC) classification type 2, 3, or 5 was used to define bleeding events. Overall, 539 patients were included in the study (mean age: 82.5 ± 4.8°years; 282 (52.3%) females). Of these patients, 69 (12.8%) developed in-hospital bleeding. Factors that were independently related with in-hospital bleeding were age (odds ratio (OR): 1.08; 95% confidence interval (CI): 1.011.14, P = .01), acute kidney injury (OR: 3.66; 95% CI: 2.016.69; P < .01), tirofiban (OR: 4.43; 95% CI: 1.7810.99; P < .01), and ticagrelor (OR: 1.93; 95% CI: 1.013.73; P = .04) administration. The urinary tract was the most frequent bleeding site, followed by femoral arteries. In conclusion, ticagrelor and tirofiban should be used with caution in elderly ACS patients.

The Rate of Coronary Angiography Refusal in Older Patients with Non-ST Elevation Acute Coronary Syndrome and Its Impact on All-Cause Mortality.

Objectives: Significant number older patients with acute coronary syndrome (ACS) cannot undergo coronary angiography (CAG) due to various comorbidities. Patient's refusal of invasive procedures is common among old patients and has not been thoroughly investigated in the context of ACS. We wanted to assess CAG refusal rate and its impact on all-cause mortality in older patients with non-ST elevation acute myocardial infarction. Methods: In this retrospective study, patients over 75 years of age admitted with acute non-ST elevation ACS were included in the study. Patients were divided into three groups based on the treatment strategy; Group 1: Those who underwent CAG; Group 2: Refused; and Group 3: Deemed unsuitable for procedure due to severe comorbidities. The primary outcomes were to assess the patient refusal rate and its impact on all-cause mortality. Results: The study included 201 elderly patients. Eighty-two (41%) patients did not undergo CAG and of those, 48 (24%) had severe comorbidities, and 34 (17%) refused the procedure. The in-hospital mortality for patients who underwent, refused, or could not undergo CAG was 5.0%, 0%, and 16.7% (p<0.01); 30-day mortality 8.5%, 9.1%, and 25% (p=0.01); and long-term mortality was 20.2%, 35.3%, and 47.9% (p<0.01), respectively. The median follow-up was 12 months. Hazard ratio of treatment refusal for long-term mortality was 1.97 (1.02-3.87, 95% CI). Conclusion: Substantial number of elderly patients with ACS refuses to undergo CAG and this leads to increased mortality. Factors affecting patient behavior and the decision-making process should be explored.

Assessment of electrocardiographic criteria for the diagnosis of left ventricular hypertrophy in the octogenarian population.

BACKGROUND: Although there are several electrocardiographic (ECG) diagnostic criteria for identifying left ventricular hypertrophy (LVH), the sensitivity of these criteria remains low. Recently, the Peguero-Lo Presti criterion provides a higher sensitivity than the current criteria. We aimed to test this ECG criterion prospectively, in the octogenarian population. METHODS: We prospectively enrolled outpatients over 80 years of age who were referred to our echocardiography laboratory. The Peguero-Lo Presti criterion was assessed along with other established ECG criteria. Left ventricular mass was calculated by echocardiography. Performance of ECG indices in diagnosing LVH were evaluated. RESULTS: Overall, 119 patients were included in the study. The sensitivity and specificity of the Peguero-Lo Presti criterion were 62.5% and 87.3%, respectively. In addition, the highest sensitivity belonged to the Peguero-Lo Presti criterion, and the highest AUC value was also seen in this criterion (AUC: 0.787, 95% CI, 0.698-0.876, P < .001). CONCLUSION: The Peguero-Lo Presti criteria showed the highest sensitivity for LVH detection, and it outperformed the other validated criteria in this octogenarian population. The Peguero-Lo Presti criteria seemed to be more effective for diagnosing LVH in this setting.

Comparing the Prognostic Value of Hematological Indices in Patients With ST Segment Elevation Myocardial Infarction: "A Head to Head" Analysis.

Although there are reviews and meta-analyses focusing on hematological indices for risk prediction of mortality in patients with ST segment elevation myocardial infarction (STEMI), there are not enough data with respect to direct to head-to-head comparison of their predictive values. We aimed to investigate which hematological indices have the most discriminatory capability for prediction of in-hospital and long-term mortality in a large STEMI cohort. We analyzed the data of 1186 patients with STEMI. In-hospital and long-term all-cause mortality was defined as the primary end point of the study. In-hospital mortality rate was 8.6% and long-term mortality rate 9.0%. Although the neutrophil to lymphocyte ratio (NLR) and age were found to be independent predictors of in-hospital mortality in the multivariate regression analyses; Cox regression analysis revealed that age, ejection fraction, red cell distribution width (RDW), and monocyte to high-density lipoprotein ratio (MHDLr) were independently associated with long-term mortality. Neutrophil to lymphocyte ratio had the highest area under curve value in the receiver operating characteristic curve analyses for prediction of in-hospital mortality. In conclusion, while NLR may be used for prediction of in-hospital mortality, RDW and MHDLr ratio are better hematological indices for long-term mortality prediction after STEMI than other most common indices.

Prognostic impact of infection in octogenarians with ST-segment elevation myocardial infarction.

PURPOSE: Contemporary studies assessing outcomes in octogenarian patients presenting with ST-segment elevation myocardial infarction (STEMI) and infection are scarce. This study investigated the impact and prognostic value of infection on long-term mortality in octogenarian patients with STEMI. METHODS: A total of 1564 patients admitted with STEMI between May 2015 and September 2019 were retrospectively analyzed, and 110 octogenarians were identified and included. Predictors of mortality were determined by multivariate Cox regression analysis. Survival curves were generated using the Kaplan-Meier method. RESULTS: The mean age of the patients was 85 ± 4 years, and 58 (52%) were male. Median follow-up was 41 months. Patients with infection had higher rates of in-hospital (16.4% vs. 8.2%, p = 0.001) and long-term (33.6% vs. 20%, p = 0.001) mortality. Multivariate Cox regression analysis revealed that infection (HR 3.16; 95% CI 1.52-6.59; p = 0.002) and C-reactive protein levels (HR 0.99; 95% CI 0.98-1.00; p = 0.042) were independent predictors of mortality in patients with infection. Kaplan-Meier analysis also showed that patients with infection had a significantly higher mortality rate (p < 0.001). CONCLUSION: Infection is an independent predictor of long-term mortality in octogenarian patients with STEMI.

Prognostic Value of the Neutrophil-to-Lymphocyte Ratio in Patients With Myocardial Infarction With Non-obstructive Coronary Arteries.

Myocardial infarction with non-obstructive coronary arteries (MINOCA) is a heterogeneous entity with an inflammatory etiopathogenesis. This study investigated the prognostic value of the neutrophil-to-lymphocyte ratio (NLR) in patients with MINOCA. Coronary angiographies performed between June 2015 and August 2018 were analyzed retrospectively and included 72 patients with MINOCA and 248 controls with normal coronary angiograms. The predictors of mortality were determined by univariate Cox regression analysis. The mean age of the subjects was 46 ± 9 years, and 176 (55%) were female. Median follow-up was 21 (max: 42) months. Neutrophil-to-lymphocyte ratio was significantly higher in the MINOCA group than in the controls (P < .01). During long-term follow-up, the number of deaths was 6 in the MINOCA group and none in the control patients (P < .01). Univariate Cox regression analysis revealed that the NLR (hazard ratio: 1.24, 95% confidence interval: 1.09-1.41, P = .001) was a predictor of mortality in patients with MINOCA. Kaplan-Meier analysis also showed that patients with MINOCA had relatively higher mortality rate (long-rank test; P < .01). In conclusion, the NLR is significantly higher in patients with MINOCA compared with controls, and it is a predictor of long-term mortality.

Assessment of Tp-e interval and Tp-e/QT ratio in patients with human immunodeficiency virus.

OBJECTIVE: Sudden cardiac death (SCD) plays an important part in all-cause mortality in patients infected with human immunodeficiency virus (HIV). The T-peak to T-end (Tp-e) interval, corrected Tp-e (Tp-ec) interval, and Tp-e/QT ratio on the ECG are parameters used to stratify risk for SCD. The objective of this study was to investigate the differences between HIV-infected patients and healthy individuals in terms of Tp-e interval, Tp-ec interval, and Tp-e/QT ratio, as well as other influencing factors. METHODS: Ninety-eight HIV-infected patients and 62 healthy controls were included in this prospective case-control study. Tp-e interval, Tp-ec interval, and Tp-e/QT ratio were measured in all participants. Echocardiographic examination and routine laboratory analysis were performed. In addition, CD4 T-cell count and HIV RNA levels were assessed in HIV-infected patients. RESULTS: All baseline characteristics were comparable in both groups. The median survival of those living with HIV was 20.63 months; 53% of them had controlled viral load, and 74% were receiving antiretroviral therapy. Mean baseline CD4 T-cell count was 409. In HIV-infected patients, the Tp-e interval and Tp-ec interval were prolonged, and the Tp-e/QT ratio was higher (p<0.001, p<0.001 and p=0.021, respectively). In bivariate and partial correlation analyses, there was a negative correlation between CD4 T-cell level and Tp-e interval, Tp-ec interval, and Tp-e/QT ratio. CONCLUSION: Tp-e interval, Tp-ec interval, and Tp-e/QT ratio were greater in HIV-infected patients compared with healthy individuals. HIV-infected patients, particularly those with low baseline CD4 T-cell counts, should be closely monitored due to risk of SCD.

The predictive value of stress hyperglycemia on thrombus burden in nondiabetic patients with ST-segment elevation myocardial infarction.

: It is established that hyperglycemia directly effects the platelet functions and fibrin structure. In this study, we aimed to investigate the predictive value of hyperglycemia on thrombus burden in nondiabetic patients with ST-segment elevation myocardial infarction (STEMI) who underwent to primer percutaneous coronary intervention (PPCI). We enrolled 619 nondiabetic patients with STEMI who received PPCI. Patients were divided two groups according to thrombus burden. Stress hyperglycemia was determined as blood glucose concentration more than 180 mg/dl and angiographic coronary thrombus burden was scored based on thrombolysis in myocardial infarction thrombus grades. Patients with thrombus grades 4 were defined as large thrombus burden (LTB), patients with thrombus burden less than thrombus grades 4 were defined as small thrombus burden. A total of 68 (11.0%) STEMI patients had stress hyperglycemia, while 223 (36.0%) patients had LTB. Sex, the prevalence of hypertension, smoking, and dyslipidemia were not different between the thrombus burden groups (P > 0.05 for all parameters). Compared with the patients with small thrombus burden, the patients with LTB were had significantly higher admission blood glucose concentrations (135 ±â€Š39.1 mg/dl vs. 145.9 ±â€Š43.1, P = 0.002, respectively). The multivariate logistic regression analysis demonstrated that stress hyperglycemia is an independent predictor of LTB (odds ratio: 3.025, confidence interval 1.200-7.622, P = 0.019). Admission hyperglycemia is associated with the LTB which cause adverse cardiac outcomes. Hyperglycemia may play a role on thrombus development.

Acute effects of synthetic cannabinoids on ventricular repolarization parameters.

OBJECTIVE: An association between ventricular repolarization parameters (VRPs) and ventricular arrhythmias has been demonstrated in previous studies. However, there are limited data related to a relationship between synthetic cannabinoids (SCs) and VRPs. The aim of this study was to analyze the acute effects of SCs on VRPs using electrocardiogram (ECG) measurements of the T-peak to T-end interval (Tp-e), Tp-e/QT ratio, and Tp-e/corrected QT (QTc) ratio. METHODS: The present study included 58 patients who were admitted to the emergency department who used SCs (SC +) between 2014 and 2016, and 50 healthy control subjects (SC -). The QT and QTc intervals, Tp-e interval, Tp-e/QT, and Tp-e/QTc ratios were measured from a 12-lead ECG. These parameters were compared between groups and correlation analysis was performed. RESULTS: The Tp-e and QTc intervals were significantly higher in SC + patients when compared with the SC- group (92.2±177;10.0, 77.4 ±177;9.3, p<0.001; 434.5±177;30.8, 410.9±177;27.3, p<0.001, respectively). Tp-e/QT and Tp-e/QTc ratios were greater in SC + patients in comparison with SC - participants (0.26±177;0.02, 0.22±177;0.02, p<0.001; 0.21±177;0.02, 0.18±177;0.02, p<0.001, respectively). Significant correlations were found between the use of SCs and the Tp-e interval (r=0.610; p<0.001), Tp-e/QT (r=0.655; p<0.001) and Tp-e/ QTc ratios (r=0.437; p<0.001). CONCLUSION: The Tp-e interval, Tp-e/QT and Tp-e/QTc ratios were greater in subjects who used SCs. Therefore, SC users might have an increased risk of ventricular arrhythmia.

Can Thrombus Burden Predict Contrast-Induced Nephropathy in Patients With ST-Segment Elevation Myocardial Infarction?

The incidence of contrast-induced nephropathy (CIN) increases in the range from patients with unstable angina to ST-segment elevation myocardial infarction (STEMI). Platelet activation has been associated with pathophysiology of nephropathy and thrombus burden in the infarct-related arteries. We investigated the impact of thrombus burden on CIN in patients with STEMI. We enrolled 883 patients with STEMI who received primary percutaneous coronary intervention. Patients were divided into groups according to thrombus burden and CIN development. Thrombus burden was scored based on thrombolysis in myocardial infarction thrombus grades (TGs). Thrombus grade 4 was defined as large thrombus burden (LTB), while thrombus burden

In-hospital Outcomes of Patients with ST-segment Elevation Myocardial Infarction who were Intubated before Primary Percutaneous Intervention: Experience of a tertiary center.

OBJECTIVES: ST-segment elevation myocardial infarction (STEMI) complicated by respiratory failure is associated with a greater number of in-hospital and out-of-hospital adverse cardiovascular events (CVEs). The aim of this study was to analyze in-hospital outcomes and the factors affecting the outcomes of intubated patients diagnosed with STEMI who underwent primary percutaneous coronary intervention (pPCI) at a single tertiary care center. METHODS: The data of 592 patients diagnosed with acute STEMI who were admitted to the emergency department between May 2017 and January 2019 and subsequently underwent pPCI were retrospectively reviewed. Cardiovascular risk factors as well as biochemical and angiographic characteristics of patients who were intubated in the emergency room or ambulance due to cardiac arrest and those who were not intubated were compared. Adverse CVEs were defined as in-hospital death, cerebrovascular stroke, and acute stent thrombosis. RESULTS: A total of 60 patients (70% male; mean age: 63.6±14.0 years) who were intubated and 532 non-intubated patients (81% male; mean age: 60.2±12.1 years) were included in the study. The angiographic features of the 2 groups were similar. An adverse CVE was experienced by 43.3% of the intubated patients and 3.6% of the non-intubated patients. Multivariate analysis indicated that age (odds ratio [OR]: 1.065; p<0.001), serum lactate level (OR: 1.308; p<0.001), and left ventricle ejection fraction (OR: 0.946; p<0.001) were independent predictors of in-hospital adverse CVE in the intubated patient group. CONCLUSION: The results of this single-center study showed that 1 in 10 patients hospitalized with STEMI were intubated, and approximately 4 in 10 intubated STEMI patients had an in-hospital CVE.

Evaluation of Subtle Left Ventricular Systolic Dysfunction by Longitudinal Systolic Strain in Patients with Human Immunodeficiency Virus.

BACKGROUND: Although left ventricular systolic dysfunction (LVSD) is a major cause of morbidity in human immunodeficiency virus (HIV)-infected patients, there is limited data on cardiac functions of these patients. Compared to the conventional echocardiography, the global longitudinal strain (GLS) can detect subclinical myocardial dysfunction at an earlier stage. OBJECTIVES: In our study, we aimed to evaluate left ventricular systolic functions using the GLS in HIV-infected patients and to investigate the effect of cluster of differentiation 4 T-cell values on LVSD. METHODS: This prospective, case-control study included a total of 65 HIV-infected patients and 48 healthy volunteers. Conventional and strain echocardiography were performed on all participants. In HIV-infected patients, CD4 T-cell counts and HIV-ribonucleic acid (HIV-RNA) values were measured. RESULTS: The median CD4 T-cell count was 529.65 cells/mm3 in the HIV-infected patients and median duration of living with HIV was 16.25 (range: 2 to 120) months. Baseline characteristics and left ventricular ejection fraction values were similar in both groups. However, there was a significant difference in the low-density lipoprotein cholesterol, triglycerides, interventricular septum, left ventricular posterior wall, and GLS between the groups (p = 0.013, p = 0.005, 0.041, p = 0.013, and p = 0.003, respectively). There was a positive correlation between GLS and CD4 levels (r = 0.463, p < 0.001). CONCLUSIONS: Our study results suggest that reduced CD4 T-cell counts in HIV-infected patients may cause myocardial dysfunction and GLS can be useful to show subtle LVSD asymptomatic cases.

Evaluation of Epicardial Fat Thickness in Young Patients With Embolic Stroke of Undetermined Source.

OBJECTIVES: Epicardial adipose tissue is metabolically active and is an important predictor of metabolic and cardiovascular diseases. This study investigated the echocardiographic epicardial adipose tissue measurement in young patients with embolic stroke of undetermined source (ESUS). MATERIALS AND METHODS: We studied 77 volunteers, including 40 patients with ESUS (mean age 43±8 y, 16 female patients) and 37 healthy subjects (mean age 38±7 y, 20 female subjects). All necessary biochemical parameters were analyzed, and epicardial fat thickness (EFT) was measured by echocardiography in all subjects. Additional related diagnostic work-up was conducted in each patient, according to the patients' clinical presentation. RESULTS: The patients with ESUS had a significantly higher EFT than the control group (5.51±0.82 vs. 3.96±0.51; P<0.01). Furthermore, there was a positive correlation between EFT and serum C-reactive protein levels (r=0.284; P<0.05). As an optimal cut-off point, a high-risk EFT value of 4.6 mm was determined to predict ESUS, with an 87.5% sensitivity and an 81.1% specificity. CONCLUSION: We found that echocardiographic EFT was significantly higher in young patients with ESUS than in healthy individuals. Increased EFT might be a novel risk factor in these patients.

Catheter induced aortocoronary dissection during percutaneous coronary intervention: successful aortoostial stenting.

Iatrogenic acute dissection of the ascending aorta is a serious but rare complication of cardiac catheterization and percutaneous coronary intervention (PCI). Although treatment of ascending aortic dissection may require surgical repair, stenting at the origin of the dissection area may be sufficient in aortocoronary dissection (AD) following PCI. Described is the case of a 64-year-old female patient who was treated with PCI for a critical lesion of the right coronary artery (RCA). Immediate stenting at the source of the dissection was sufficient to repair the RCA lesions and successfully seal the site of retrograde propagation of the dissection. The ascending aortic dissection was monitored with computed tomography and the dissection was spontaneously repaired within 72 hours.
