Feasibility of Distal Radial Access in High Bleeding Risk Patients Who Underwent Percutaneous Coronary Intervention.

Backgrounds And Objectives: The distal radial access (DRA), a potential alternative to the trans-radial approach (TRA), may offer advantages in terms of access site complications due to its smaller vessel diameter, especially for high bleeding risk (HBR) patients. This study aims to investigate the feasibility of DRA in HBR patients.

Methods: Based on data from the KODRA registry, a prospective, multicenter cohort, this study analyzed 1,586 patients who underwent successful percutaneous coronary intervention (PCI) via DRA.

Concurrent spontaneous coronary dissection and reversible cerebral vasoconstriction syndrome during postnatal care.

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.

Distal Radial Access for Coronary Procedures in a Large Prospective Multicenter Registry: The KODRA Trial.

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.

Endovascular treatment of Takayasu arteritis in a middle-aged woman with syncope and limb claudication: a case report.

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.

The long-term prognostic value of E/e' in patients with ST segment elevation myocardial infarction.

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).

Safety concern with electrical cardioversion of persistent atrial fibrillation with slow ventricular response.

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.

Emphysematous myocardial abscess without infective endocarditis.

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.

Large left ventricular non-infectious vegetation in patient with eosinophilic granulomatosis with polyangiitis.

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.

Benign posterior mediastinal schwannoma-Multiple diagnostic imaging modalities.

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.

Feasibility of right coronary artery first ergonovine provocation test.

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.

Surgical Repair of Aortocaval Fistula Presenting with Cardiogenic Shock.

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.

Delayed left ventricular pseudo-aneurysm after postinfarction repair of ventricular septal defect.

Left ventricular pseudo-aneurysm is a rare complication that usually occurs after myocardial infarction or cardiac surgery. Sometimes it is related to cardiac rupture. We report on surgical management for a left ventricular pseudo-aneurysm that developed four years after surgery for ventricular septal defect in a patient with acute myocardial infarction.

Local Atrial/Ventricular Ratio as an Adjuvant Marker for Catheter Ablation of Atrioventricular Accessory Pathways.

Background And Objectives: The earliest atrial (A)/ventricular (V) activation potential, or accessory pathway (AP) potential are commonly used as ablation targets for atrioventricular (AV) APs. However, these targets are sometimes ambiguous.

Subjects And Methods: We reviewed 119 catheter ablation cases in 112 patients diagnosed with orthodromic atrioventricular reentrant tachycardia (AVRT) or Wolff-Parkinson-White (WPW) syndrome.

Extension of catheter ablation and outcome for ventricular tachycardia or premature ventricular contractions from the right ventricular outflow tract.

Objective We aimed to determine whether the extension of ablation could influence the ablation outcome for ventricular tachycardia (VT)/premature ventricular contractions (PVCs) from the right ventricular outflow tract (RVOT). Methods and results The radiofrequency catheter ablation results of 33 VT/6 frequent PVCs from the RVOT were analysed. The ablation extension was divided into 3 categories from the final successful ablation point with the earliest activation: (I) focal ablation (15 cases); ablation at 1 or 2 points; (II) focal with extended ablation (12 cases); focal and surrounding area ablation (maximum ≤1 cm) after elimination of clinical VT/PVCs; and (III) broad ablation (12 cases); continued broad ablation (maximum >1 cm) after elimination of clinical VT/PVCs.
