Background: Myeloproliferative disorders, including monoclonal gammopathy of undetermined significance (MGUS), are often associated with amyloid light-chain (AL)-type cardiac amyloidosis (CA) but occasionally with wild-type transthyretin (ATTR) CA. In recent years, ATTR amyloidosis has attracted necessity for its reliable diagnosis with the addition of new treatments. Usually, both wild-type ATTR CA and AL-type CA present with marked cardiac hypertrophy, but renal dysfunction is milder in wild-type ATTR amyloidosis than in AL-type amyloidosis.

- A study examined the clinical characteristics and future cardiac event risks of young females (under 60) undergoing percutaneous coronary intervention (PCI), revealing limited existing data on this demographic.
- Among 187 participants, almost half had diabetes, and 20.3% exhibited renal dysfunction.
- Findings indicated that renal dysfunction and multivessel disease were significant predictors of serious cardiac events, with patients experiencing renal issues facing a threefold increased risk.
Background And Objectives: Mitral isthmus (MI) ablation for mitral flutter is technically difficult, and incomplete block line is not uncommon. The objective of this study is to investigate the effect of the ridge line of left pulmonary vein isolation (LPVI) from left atrial appendage (LAA) on completion rate of mitral isthmus (MI) block line and recurrence rate of atrial tachycardia (AT) or atrial flutter (AFL) after the first MI ablation.
Methods: We identified 611 patients who underwent first MI ablation for mitral flutter during the study period.
Article Synopsis
- The study investigated the effectiveness of two different ablation techniques—empirical linear ablation and low-voltage area (LVA) ablation—following pulmonary vein isolation (PVI) for patients with persistent atrial fibrillation (PeAF).
- A total of 128 PeAF patients were divided into two groups, with the LVA group showing significantly lower recurrence rates of atrial fibrillation compared to the linear group during an average follow-up period of about 280 days.
- The LVA ablation technique required less radiofrequency energy and resulted in shorter procedural times than the linear ablation approach, indicating it might be a more efficient option for treating patients with LVA after PVI.
Article Synopsis
- A survey in Japan explored cases of acute coronary syndrome (ACS) in young adults previously diagnosed with Kawasaki disease (KD), revealing that many had low conventional coronary risks and experienced significant heart issues like myocardial infarction.
- Out of 67 patients studied, a higher percentage of those diagnosed with KD during their acute illness (Group A) developed ACS at a younger age and with fewer coronary risk factors compared to those diagnosed retrospectively (Group B).
- The study highlighted alarming outcomes, including a one-month mortality rate of 19%, with notable characteristics of the culprit lesions in Group A featuring large aneurysms and minimal significant stenosis over a long-term follow-up.
The patient was a 62-year-old man with atrial fibrillation and severe scoliosis. Scoliosis may impair cardiorespiratory function. Enhanced computed tomography (CT) was helpful for the Brockenbrough method.

However, little is known about the long-term clinical outcomes of AF after RFCA in HD patients.
Methods: Between 2002 and 2008, 16 HD patients (age: 63.
