The use of percutaneous coronary intervention (PCI) and coronary artery bypass graft (CABG) have reportedly improved patient outcomes since their introduction . Thus, early detection and treatment for CAD may further reduce the mortality rate. Asymptomatic CAD occurs in 15% of patients aged <70 years and in 28% of those aged >70 years . Therefore, a highly sensitive screening method is required to detect CAD in these individuals. Some studies report that stress testing with electrocardiography, echocardiography, and scintigraphy monitoring, and the use of coronary computed tomography (CT) to measure the coronary calcium level are useful for CAD screening . However, these tests are expensive and time-consuming in some clinical settings, which reduces their feasibility.

Our patient was an 85-year-old man who experienced anterior STEMI (peak creatine kinase = 5286 U/L) and fulfilled the criteria of classical LFLG-AS (aortic valve area = 0.68 cm 2 , LVEF = 16%, and MPG = 20 mmHg).

We performed A-BAV for hemodynamic restoration. A few days after successful A-BAV, tapering of norepinephrine and weaning of IABP were initiated. A cardiac rehabilitation program was initiated during the intensive care period, and which facilitated the patient to be discharged.

Postoperative AF is associated with complications including an increased risk of stroke and a need for additional treatment, as well as a prolonged intensive care unit or hospital stay and increased hospitalization costs. The incidence of postoperative AF in off-pump coronary artery bypass grafting (CABG) is similar to conventional CABG with cardiopulmonary bypass. β-blockers are widely used during the perioperative periods in cardiac surgery. The ACCF/AHA guidelines recommend that β-blockers should be administered for at least 24 hours before CABG in all patients without contraindications, should be reinstituted as soon as possible after CABG, and should be prescribed to all CABG patients at the time of hospital discharge. Landiolol hydrochloride (Onoact ® ; Ono Pharmaceutical Co., Osaka, Japan), is an ultrashort acting β-blocker, with a halflife of 4 minutes and a higher β-selectivity than any currently available β-blocker. Recently, some meta-analyses have shown that landiolol administration signifi cantly reduces the incidence of postoperative AF following cardiac surgery-. The effectiveness of landiolol was similar for both valvular surgery and CABG, even with off-pump CABG. High right atrial overdrive pacing for patients with paroxysmal AF reduces the recurrence of AF when compared with ventricular demand pacing in observational and controlled clinical trials . Several randomized controlled studies of either right, left, or biatrial pacing to prevent postoperative AF following CABG or valve surgery and to reduce the length of the hospital stay were performed-. Although the role of postoperative β-blockers in combination with atrial pacing has been pointed out as benefi cial, the effi cacy of this combination therapy is still a matter of debate.
