RESUMO

BACKGROUND: Pregnancy-associated spontaneous coronary artery dissection (SCAD) and reversible cerebral vasoconstriction syndrome (RCVS) are rare conditions that may occur during pregnancy and the postpartum period. The coexistence of both diseases may pose a risk to patients, potentially resulting in a variety of complications and clinical manifestations. This is considered the first case of a patient who successfully recovered from a critical condition in the postpartum period, with contemporaneous SCAD and RCVS. CASE PRESENTATION: A 33-year-old female with no known medical history was referred to the emergency department after experiencing cardiac arrest, which occurred 1 week after giving birth to her third child. She complained of sudden anterior squeezing chest pain, accompanied by a headache, and eventually collapsed due to ventricular fibrillation with seizure. She was successfully resuscitated after receiving basic life support. She showed an alert mentality and did not experience any further seizure events or additional neurological symptoms. Although vital sign remained stable, the level of highly sensitive troponin I was significantly elevated. Electrocardiography revealed sinus rhythm with T-wave inversion at V1-4, while chest computed tomography (CT) demonstrated severe aspiration pneumonia. The patient was admitted to the intensive care unit due to a high requirement of O2 supply. A consultation with the neurologic department and a brain magnetic resonance angiography (MRA) were conducted for the thunderclap headache. The brain MRA demonstrated stenosis in the basilar artery, the right M2 segment, and bilateral A1 segments, along with sulcal hyperintensity on post-contrast fluid-attenuated inversion recovery (FLAIR) suggesting blood-brain barrier breakdown due to vasoconstriction. Formal echocardiography showed regional wall motion abnormality in the left anterior descending artery (LAD) territory. After the improvement of pneumonia, a coronary angiography was performed, revealing diffuse luminal narrowing from the mid to distal LAD due to a long segmental, extensive dissection. We decided to maintain the medical therapy. A follow-up coronary CT angiography performed 6 months later revealed complete remission of the dissected coronary vessel, and a brain MRA checked 3 months later showed resolved vasoconstriction of the relevant cerebral vessels. CONCLUSIONS: The physicians must be aware of pregnancy-associated complications in certain patients. Clear diagnoses and proper treatments are required in pregnant patients who may be exposed to multiple acute conditions, in order to reduce complications and achieve favorable outcomes.

RESUMO

BACKGROUND: Distal radial access (DRA) as an alternative access route lacks evidence, despite its recent reputation. OBJECTIVES: The aim of this study was to evaluate the safety and feasibility of DRA on the basis of daily practice. METHODS: The KODRA (Korean Prospective Registry for Evaluating the Safety and Efficacy of Distal Radial Approach) trial was a prospective multicenter registry conducted at 14 hospitals between September 2019 and September 2021. The primary endpoints were the success rates of coronary angiography (CAG) and percutaneous coronary intervention (PCI). The secondary endpoints included successful distal radial artery puncture, access-site crossover, access site-related complications, bleeding events, and predictors of puncture failure. RESULTS: A total of 4,977 among 5,712 screened patients were recruited after the exclusion of 735 patients. The primary endpoints, the success rates of CAG and PCI via DRA, were 100% and 98.8%, respectively, among successful punctures of the distal radial artery (94.4%). Access-site crossover occurred in 333 patients (6.7%). The rates of distal radial artery occlusion and radial artery occlusion by palpation were 0.8% (36 of 4,340) and 0.8% (33 of 4,340) at 1-month follow-up. DRA-related bleeding events were observed in 3.3% of patients, without serious hematoma. Multilevel logistic regression analysis identified weak pulse (OR: 9.994; 95% CI: 7.252-13.774) and DRA experience <100 cases (OR: 2.187; 95% CI: 1.383-3.456) as predictors of puncture failure. CONCLUSIONS: In this large-scale prospective multicenter registry, DRA demonstrated high success rates of CAG and PCI, with a high rate of puncture success but low rates of distal radial artery occlusion, radial artery occlusion, bleeding events, and procedure-related complications. Weak pulse and DRA experience <100 cases were predictors of puncture failure. (Korean Prospective Registry for Evaluating the Safety and Efficacy of Distal Radial Approach [KODRA]; NCT04080700).

RESUMO

Takayasu arteritis (TA) is a disease that causes inflammation and stenosis of medium to large blood vessels. We report a case of a 50-year-old female patient with newly developed hypertension, syncope, and claudication of the extremities. Total occlusion of the left subclavian artery at the origin was found and significant stenosis of the right common iliac artery was revealed by hemodynamic analysis. She was successfully treated with percutaneous angioplasty for multiple peripheral arterial diseases and was finally diagnosed with TA. In consultation with a rheumatologist, medical treatment for TA was initiated, the patient's hypertension disappeared, and her claudication symptoms improved.

RESUMO

OBJECTIVES: This study aimed to evaluate the long-term prognostic value of E/e' ratio in patients with ST-segment elevation myocardial infarction (STEMI). METHODS: We retrospectively assessed 314 patients who underwent primary coronary interventions between January 2010 and December 2015. The included patients were classified into two groups according to the E/e' ratios: E/e'<15 (n = 245) and E/e'≥15 (n = 69). We investigated the incidence of major adverse cardiac events (MACEs) from the event to the final follow-up period of at least three years. RESULTS: A total of 55 cases of MACEs occurred during the follow-up. The E/e'≥15 group showed a significantly higher rate of MACEs than the E/e'<15 group (34.8% vs. 12.7%, p < 0.001). Among the MACE, the percentage of cardiac deaths (17.4% vs. 0.4%, p < 0.001) was higher in the E/e'≥15 group than in the E/e'<15 group. In the multivariable model, E/e'≥15 was demonstrated as the strongest prognostic factor for MACEs (hazard ratio [HR], 2.597; 95% confidence interval [CI], 1.294-5.211; p = 0.007) and cardiac death (HR, 27.537; 95% CI, 3.287-230.689; p = 0.002), while left ventricular ejection fraction (LVEF) was not. Neither the discrepancy of systolic nor diastolic function between initial and follow-up echocardiography affected the overall prevalence of MACEs. A disparity was observed between the two groups, with a significant increase in the rate of MACEs in the E/e'≥15 group (log-rank test, p < 0.001). CONCLUSION: The baseline E/e'≥15 in patients with STEMI after successful reperfusion is the strongest predictor of poor long-term clinical outcomes among those analyzed.

RESUMO

Rhythm control strategies in patients with atrial fibrillation (AF) can bring many clinical benefits. However, there is still uncertainty regarding selection of the optimal rhythm control strategy for persistent AF. Chronicity, substrate alteration, and underlying bradyarrhythmias could influence the clinical outcomes. Current guidelines do not provide a distinct recommendation for electrical cardioversion (ECV) in patients with AF with a slow ventricular response (SVR). We present two cases of sudden cardiac arrest due to sustained ventricular tachycardia/fibrillation after ECV of persistent AF with SVR.

RESUMO

Diagnosis of myocardial abscess without endocarditis is challenging, and a high index of clinical suspicion is fundamental for diagnosis. It should never be ruled out before TEE. And CT could be a helpful modality in case of emphysematous morphology.

RESUMO

BACKGROUND: Intracoronary (IC) provocation angiography is recommended when variant angina is suspected. However, specific procedure-related factors remain uncertain. METHODS: Intracoronary ergonovine infusion was used for the provocation test. About 10, 20, and 40 µg of ergonovine were sequentially injected into the right coronary artery (RCA). During a negative or intermediate response or depending on the clinician's discretion, the left coronary artery (LCA) was injected with incremental doses of 20, 40, and 80 µg of ergonovine or vice versa. If significant coronary spasm or positive clinical findings were noted, the test was stopped immediately and IC nitroglycerine was injected. RESULTS: We reviewed a total of 725 patients (male: 402; mean age: 58.5 years). Spasm-positive response was observed in 269 patients (37.1%), intermediate response in 113 patients (15.6%), and negative response in 343 patients (47.3%). The right radial artery approach was used in most cases (92.6%), and the RCA first approach was mainly chosen (95.0%). The provocation results in the RCA and LCA (93.4%, 381/408) were highly consistent, and the clinically significant discrepancy rate (RCA positive/LCA negative or RCA negative/LCA positive) was 1.5% (6/408). The RCA-alone provocation test can identify spasm-positive response in 93.4% of the patients (228/244). The mean procedure time was 39.9 ± 11.0 min, and approximately 3.3% (24/725) of the patients developed acute complications. CONCLUSIONS: The RCA-first IC ergonovine provocation test is feasible, and the RCA-alone spasm provocation could be acceptable except in an intermediate response, highly clinically suspected cases, or high-risk patients.

RESUMO

Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare form of systemic vasculitis in which cardiac involvement is relatively common and accounts for half of EGPA-related deaths. Cardiac involvement is more frequent in patients with an absence of anti-neutrophil cytoplasmic antibody and those with higher eosinophil counts. Clinical manifestations are various, including myocarditis, pericarditis, pericardial effusion, heart failure, arrhythmias, valvular insufficiencies and intra-cardiac thrombus formation. The pathology of cardiac involvement in EGPA is usually endomyocardial and pericardial eosinophilic infiltration. Considering the potentially adverse outcomes associated with cardiac involvement in EGPA, early detection is important. We experienced a rare case of EGPA with cardiac involvement presenting with non-infectious vegetations.

RESUMO

Schwannoma is usually benign, encapsulated spindle cell tumor which arises from schwann cells of nerve sheath, and is the most common of the neurogenic mediastinal tumors. Various imaging modalities can be applied to assess posterior mediastinal mass which is often found incidentally without symptom and frequently misdiagnosed for other benign conditions both clinically and radiologically in which clinicians should be aware of.

RESUMO

Aortocaval fistula (ACF) occurs in <1% of all abdominal aortic aneurysms (AAAs), and in 3% to 7% of all ruptured AAAs. The triad of clinical findings of AAA with ACF are abdominal pain, abdominal machinery bruit, and a pulsating abdominal mass. Other findings include pelvic venous hypertension (hematuria, oliguria, scrotal edema), lower-limb edema with or without arterial insufficiency or venous thrombus, shock, congestive heart failure, and cardiac arrest. Surgery is the main treatment modality. We report successful surgical treatment in a patient with a ruptured AAA with ACF who presented with cardiogenic shock.
