Physical frailty recovery is slower than mental frailty recovery after non-cardiac surgery in older adult patients.

Purpose: Frailty is characterized by fragility and decline in physical, mental, and social activities; it is commonly observed in older adults. No studies have reported frailty status changes between the preoperative and postoperative periods, including mental and cognitive factors. Therefore, this study investigated frailty factors, including mental and cognitive functions, that change after non-cardiac surgery in older adults.

Adult ALCAPA: from histological picture to clinical features.

Background: Anomalous left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital coronary anomaly that results in high mortality if left untreated. Our aim was to extend our knowledge of the histological, angiographic, and clinical characteristics of ALCAPA in order to deepen our understanding of this rare entity.

Case Presentation: We were involved in the assessment, treatment, and pathological evaluation of two adult ALCAPA patients who were rescued from ventricular fibrillation and then surgically treated to establish a dual coronary artery system.

Anomalous origin of the coronary artery coursing between the great vessels presenting with a cardiovascular event (J-CONOMALY Registry).

Aims: Anomalous origin of the coronary artery (AOCA) with an inter-arterial course (IAC) between the great vessels poses a risk for a life-threatening cardiovascular event. We assessed, in a registry-based study, the clinical features, treatment strategies, and prognoses of life-threatening cardiovascular events ensuant to AOCA.

Methods And Results: Included were 65 AOCA patients (48 men/17 women, aged 41 ± 23 years) from 40 clinical centres who had experienced sudden cardiac arrest (SCA) (n = 30), acute myocardial infarction (AMI) (n = 5), angina (n = 23), or syncope (n = 7).

Patency of Saphenous Vein Grafts Using the PAS-Port System During Coronary Artery Bypass Surgery.

Background: Several proximal anastomosis devices have been developed to shorten the time required for a proximal anastomosis and to avoid aortic cross-/side-clamping during coronary artery bypass grafting. This study retrospectively examined the patency of saphenous vein grafts (SVGs) using the PAS-Port System (Cardia Inc, Redwood City, CA).

Methods: From 2004 to 2014, 451 patients underwent coronary artery bypass graft operations requiring at least 1 proximal anastomosis using a PAS-Port device.

Two adult cases of Bland-White-Garland syndrome with lethal arrhythmia due to coronary steal phenomenon during physical or mental stress.

We experienced two adult cases of anomalous origin of the left coronary artery from the pulmonary artery, so-called Bland-White-Garland (BWG) syndrome, that presented with ventricular tachycardia (VT) and ventricular fibrillation during exertion in daily life. They presented to our hospital with syncope due to VT, and recovered following application of an automated external defibrillator with cardiopulmonary resuscitation. We diagnosed BWG syndrome by multi-detector computed tomography angiography and coronary angiography.

CD73-TNAP crosstalk regulates the hypertrophic response and cardiomyocyte calcification due to α1 adrenoceptor activation.

Cluster of differentiation 73 (CD73) is an ecto-5' nucleotidase which catalyzes the conversion of AMP to adenosine. One of the many functions of adenosine is to suppress the activity of tissue nonspecific alkaline phosphatase (TNAP), an enzyme important in regulating intracellular calcification. Since myocardial calcification is associated with various cardiac disease states, we studied the individual roles and crosstalk between CD73 and TNAP in regulating myocyte responses to the α1 adrenoceptor agonist phenylephrine in terms of calcification and hypertrophy.

Rupture of pseudoaneurysm of the pancreaticoduodenal arcade after acute aortic dissection in a patient on anticoagulant therapy.

An 81-year-old woman on anticoagulant therapy after mechanical heart valve replacement was admitted because of acute aortic dissection. Anticoagulant therapy had to be continued with heparin even after admission. Gastrointestinal hemorrhage occurred suddenly and she developed hemorrhagic shock.

Cardiac swinging calcified amorphous tumors in end-stage renal failure patients.

We recently encountered 2 patients with mobile cardiac calcified amorphous tumors who were successfully treated by surgery. Both patients had mitral annular calcification and were on hemodialysis. These tumors showed swinging motion on echocardiography and they grew rapidly.

A new application of the ST-HR loop to evaluate the exercise-induced reversible ischemia in healed anterior wall myocardial infarction.

Exercise-induced ST-segment elevation in infarct-related leads is often seen on the treadmill exercise electrocardiogram of patients with anterior wall myocardial infarction. However, the cause of this phenomenon is still a matter of controversy. The purpose of this study was to evaluate the relation between the direction of ST-segment-heart rate (ST-HR) loop rotation and reversible myocardial ischemia in the infarct-related area.
