A 42-year-old man was admitted to our hospital because of lumbago and tachycardia-induced heart failure. Transthoracic echocardiography revealed impaired left ventricular function a ball mass thrombus in the ventricle (LV). He found have systemic embolism spleen, kidneys, brain, limbs. The patient treated with limb thrombectomy followed by anticoagulation. Seven days after direct factor Xa inhibitor, rivaroxaban, initiated, transthoracic repeated, revealing disappearance LV without any...
Data are limited regarding outcomes of cryoballoon ablation for atrial fibrillation (AF) in patients with heart failure (HF). This large-scale multicenter study aimed to evaluate the prognosis HF after AF.Among 3655 undergoing at 17 institutions, 549 (15%) (391 paroxysmal AF and 158 persistent AF) diagnosed preoperatively were analyzed. Clinical endpoints recurrence, mortality, hospitalization ablation.Most had a preserved left ventricular ejection fraction (LVEF) ≥ 50%. During mean...
Even in the era of thrombus aspiration and distal protection for ST-segment elevation acute myocardial infarction (STEMI), microvascular dysfunction does exist improvement can improve prognosis and/or left ventricular dysfunction. We evaluated effects nitroprusside (NTP) on coronary injury that occurred after primary percutaneous intervention (PCI) STEMI 18 patients. The final Thrombolysis Myocardial Infarction trial (TIMI) flow grade PCI was 3 17 patients 2 1 patient. index microcirculatory...
Atrial fibrillation (AF) inducibility with burst pacing (BP) after radiofrequency ablation (RFA) has been reported to be associated AF recurrence. In contrast, the relevance of and recurrence cryoablation (CRA) is unclear.
In the field of coronary artery stenting, restenosis issue has been almost resolved after development drug-eluting stents (DESs). In-stent (ISR) is generally considered to be a stable process, with an early peak in intimal hyperplasia followed by quiescent period beginning 1 year stent implantation. However, recently, extended-term problem (over year) both bare-metal (BMSs) and DES reported. This phenomenon seems different from ISR within one terms its mechanism, prevention, treatment. this...
There are often false-positive alerts of thoracic impedance monitoring; however, the "false-positive alerts" might indicate any clinical problem patient. In present case, an alert for a drop in intrathoracic impedance, which generally indicates exacerbation heart failure, enabled early detection twiddler syndrome.
patient with persistent arrest was evaluated on electrophysiology and right atrial voltage mapping using a 3-D electroanatomical (CARTO) system.The system useful for visually identifying the injured area after suspected acute myocarditis.A 55-year-old man referred hospital experiencing prolonged that persisted 3 days even though he prescribed medicine at another clinic.He complained of nausea chest pain admission had no past history this.He diagnosed as having myocarditis based A
Background: Provoked spasm might have influence on cardiovascular events even after successful DES implantation. Methods and results: A consecutive 122 patients who underwent first-generation (CypherTM, TaxusTM) implantation had no residual stenosis at follow-up coronary angiography were included. All also acetylcholine provocation test (ACh) angiography. Age, sex, risk factors (smoking, hypertension, diabetes mellitus, dyslipidemia), medication (calcium channel blockers, angiotensin...
In recent years, neoatherosclerosis and very late stent thrombosis in the extended follow-up period after baremetal (BMS) implantation have been recognized. We experienced a case of in-stent restenosis (ISR) detected BMS implanted 14 years prior. An 86-year-old man who had history because angina pectoris proximal left anterior descending coronary artery (LAD) previously was referred to our hospital worsening chest pain on exertion for 1 month. A angiogram revealed severe stenosis BMS. Seven...
Background: It is not well known whether coronary endothelial dysfunction after Drug-Eluting Stent (DES) implantation affects the prognosis. Purpose: We tried to find predictors of cardiovascular events successful DES implantation. Methods: A consecutive 122 patients who underwent first generation (CypherTM, and TaxusTM) had no residual stenosis at follow-up angiography were included. All also acetylcholine provocation test (ACh) angiography. Age, sex, risk factors (smoking, hypertension,...
Atrial echo beats due to a dual-atrioventricular nodal pathway are possible cause of fluctuating tachycardia in cycle length (CL) but have not been reported so far. Here, we present case an 82-year-old man with symptomatic atrial (AT), which was accompanied by periodic fluctuations sequence at the coronary sinus. Electrophysiological study (EPS) for atrioventricular conduction and three-dimensional (3D) electro-anatomical mapping system explained that mechanism through pathway.
