Sjogren's syndrome is one of the most common autoimmune disorders and has a female predominance. Maternal circulating autoantibodies such as anti-Ro/SSA and anti-La/SSB antibodies can cause congenital heart block of fetus, and in severe case, emergency pacemaker implantation may be needed for neonate. Therefore, it is very important to understand maternal and fetal condition and pay attention to the status of the neonate during delivery. In this paper, we present a case of patient with Sjogren's syndrome who underwent cesarean section under spinal anesthesia...

We aimed to determine how age-associated changes in mechanisms extrinsic and intrinsic to pacemaker cells relate to basal beating interval variability (BIV) reduction in vivo. Beating intervals (BIs) were measured in aged (23-25 months) and adult (3-4 months) C57BL/6 male mice (i) via ECG in vivo during light anesthesia in the basal state, or in the presence of 0.5 mg mL(-1) atropine + 1 mg mL(-1) propranolol (in vivo intrinsic conditions), and (ii) via a surface electrogram, in intact isolated pacemaker tissue...

A 60-year-old woman posted for percutaneous nephrolithotomy with ureterolithotripsy was found to have a history of hypertension and ischemic heart disease from past 6 months on regular treatment. Pulse rate was irregularly irregular in a range of 56-60/min, unresponsive to atropine, with a sinus pause on the electrocardiogram. Although the patient was asymptomatic, anticipating unmasking of the sick sinus syndrome during general anesthesia in the prone position, a temporary pacemaker was implanted at right ventricular outflow tract (RVOT) septum before the scheduled surgery...

INTRODUCTION: The proportion of patients who die during or after surgery, otherwise known as the perioperative mortality rate (POMR), is a credible indicator of the safety and quality of operative care. Its accuracy and usefulness as a metric, however, particularly one that enables valid comparisons over time or between jurisdictions, has been limited by lack of a standardized approach to measurement and calculation, poor understanding of when in relation to surgery it is best measured, and whether risk-adjustment is needed...

Intracardiac thrombosis is an infrequent and fatal complication in patients with an inserted pacemaker. A patient with an inserted pacemaker scheduled for ureter stone removal experienced cardiac arrest and cardiopulmonary resuscitation under general anesthesia. Echocardiography showed multiple intracardiac thrombi. Preoperative diagnostic workup including echocardiography for the detection of pacemaker lead thrombus, and the need for anticoagulation should be considered in patients with an inserted pacemaker and high-risk factors for thrombosis...

BACKGROUND: Complete heart block in pregnancy has serious implications particularly during the period of delivery. This is more so if the delivery is an operative one as the presence of heart block may produce haemodynamic instability in the intra operative period. We report a unique case of a pregnant mother with complete heart block undergoing hysterostomy, complicated by placenta accreta and intrauterine death. CASE PRESENTATION: A 37 year old Malaysian Chinese parturient was admitted at 25 weeks gestation following a scan which suggested intrauterine death and placenta accreta...

OBJECTIVES: Valvular aortic stenosis (AS) is a major cardiac valvular disease in geriatric people. Conventional treatment for severe AS is aortic valve replacement through surgery. However, many geriatric patients are considered inoperable due to higher risks for surgery and anesthesia. Transcatheter aortic valve implantation (TAVI), a less invasive procedure, has rapidly developed in recent years as an alternative management option for high-risk AS patients. Herein, we describe our anesthetic experience in the TAVI procedure...

The number of patients with cardiac pacemaker is continuously increasing. The anesthetic management of these patients is often trivialized, particularly during minor surgery. However there is always a potential risk of dysfunction during anesthesia. Perioperative management of these patients must be careful and standardized to avoid accidents. We report a case of cardiac arrest during general anesthesia for a day-surgery secondary to pacemaker dysfunction by increasing pacing thresholds in a young adult patient...

We report a case of 30-second cardiac arrest that occurred during carotid body tumor resection due to the carotid sinus reflex. The patient was a 20-year-old man diagnosed with a carotid body tumor and scheduled for tumor resection. General anesthesia was induced and maintained with target controlled infusion of propofol. Analgesia was achieved with continuous administration of remifentanil. When the surgery was initiated, 1% lidocaine 3 ml was locally injected into the carotid bifurcation. When surgery was initiated in the neck region, the patient developed sudden cardiac arrest...

A 42-year-old woman, who presented with DCM (American Society of Anesthesia, ASA class IV), suffered from gallstone for years, and was scheduled for laparoscopic cholecystectomy. Echocardiography demonstrated a severely dilated left ventricle with global hypokinesia and reduction of left ventricular systolic function, ejection fraction (EF) 34% with mild mitral regurgitation and severe tricuspid regurgitation. After intubation, a transesophageal echocardiography (TEE) probe was inserted. When the IAP was gradually ascended to 14 mmHg during the laparoscopy, EF fell to 19% and the systolic pressure fell to 78 mmHg and TEE showed severely poor wall motion...

Sick sinus syndrome is a generalized abnormality of cardiac impulse formation that may be caused by extrinsic causes or by intrinsic disease of the sinus node making it unable to perform pace making function. It can be manifested for the first time in pregnancy. First case was diagnosed as sick sinus syndrome at 8 weeks of gestation having Mobitz type I heart block (Wenckebach block), and needed temporary pacemaker during caesarean section. Second case was diagnosed at 24 weeks of gestation having complete heart block and needed permanent pacemaker at 38 weeks of gestation due to exaggeration of the symptoms...

BACKGROUND: Biventricular pacing through the coronary sinus (CS) is effective for the treatment of patients with heart failure and left bundle-branch block. However, this approach is not always feasible. Although surgical epicardial lead implantation is an alternative, the technique may be deleterious in some patients. Thus, direct left ventricular (LV) endocardial pacing under local anesthesia may be an option. OBJECTIVE: We describe our technique and analyze the results of direct LV endocardial pacing...
