Excimer LASER coronary atherectomy for ST-segment elevation myocardial infarction: Insights from a multicenter registry.

Background: Excimer laser coronary atherectomy (ELCA) is used for thrombotic culprit lesions in ST-segment elevation myocardial infarction (STEMI), but its effectiveness is still unclear.

Methods: Consecutive patients undergoing primary percutaneous coronary intervention within 24 h of onset were retrospectively investigated. Patients were divided into ELCA and non-ELCA groups.

A case report of Bow Hunter's syndrome with intravascular ultrasound showing changing significant severe stenosis of the left vertebral artery associated with turning left.

Background: Bow Hunter's syndrome is vertebral basilar artery insufficiency caused by mechanical occlusion of the vertebral artery during head rotation. This is often due to the formation of osteophytes, herniated discs, cervical spondylosis, or tumours. However, whether the contralateral vessel is organically stenotic is not well known.

Comparison of the efficacy of excimer laser coronary angioplasty for ST-segment elevation myocardial infarction with onset-to-balloon time.

Excimer laser coronary angioplasty (ELCA) vaporizes plaques and thrombi, provides better microcirculation, and reduces peripheral embolism when treating acute coronary syndrome. Studies on the efficacy of ELCA for long onset-to-balloon time ST-segment elevation myocardial infarction (STEMI) are limited. Thus, we aimed to examine the efficacy of ELCA for STEMI using the onset-to-balloon time (OBT).

Benefits of excimer laser coronary angioplasty over thrombus aspiration therapy for patients with acute coronary syndrome and thrombolysis in myocardial infarction flow grade 0.

In primary percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS), the presence of a thrombus or unstable plaque can cause microvascular obstructions, which may increase infarct size and reduce survival. Excimer laser coronary angioplasty (ELCA) is a unique revascularization technique that can vaporize plaques and thrombi. However, to date, only few reports indicate the efficacy of ELCA for ACS.

Excimer laser coronary atherectomy prior to paclitaxel-coated balloon angioplasty for de novo coronary artery lesions.

This study aimed to evaluate the efficacy and safety of excimer laser coronary atherectomy (ELCA) prior to paclitaxel-coated balloon angioplasty for de novo coronary artery lesions. This retrospective observational study analyzed 118 eligible patients with de novo coronary artery disease whose only percutaneous coronary intervention was a drug-coated balloon angioplasty (i.e.

Rotational Atherectomy for Ablation of Multiple Channel Structure Observed by Optical Frequency Domain Imaging.

BACKGROUND Previous case reports have shown that regardless of the etiology, multiple channel structures can be treated successfully by routine percutaneous coronary intervention. However, there are no general recommendations for intervention because multiple channel structures are complex and rarely diagnosed. CASE REPORT A 71-year-old male was admitted to our hospital due to bronchial pneumonia.

[Two distinct types of neuropathy associated with Sjögren's syndrome developed in one patient. The importance of the selection of an appropriate therapeutic regimen].

A 62-year-old woman was admitted to our hospital because of muscle weakness and sensory disturbance in extremities. She showed weakness, muscle atrophy and sensory abnormality in four limbs with patchy distribution, suggesting involvement of multiple peripheral nerve trunks. Serum titers of anti-SS-A, SS-B, and antinuclear antibody were elevated.
