There are two types of tests: angiography, which diagnoses stenosis, heart movement, and valve regurgitation by imaging the coronary arteries and left ventricle, and hemodynamic testing, which measures the pressure in each part of the heart and cardiac output.During the examination, a polygraph is used to constantly monitor the patient's vital signs such as electrocardiogram, blood pressure, and oxygen saturation, and cardiac output and pressure are measured during the hemodynamic examination.In addition, we operate a contrast injection device and coronary flow reserve (FFR) measurement device.

It is a treatment for coronary artery stenosis or blockage.Many devices such as balloons, stents, rotor blades and diamondbacks are used to treat lesions.Intravascular ultrasound (IVUS) and optical coherence tomography (OFDI) are used to confirm vascular properties.In this treatment, we will take out items, set up various devices, and operate and record imaging modalities.In addition, in highly urgent cases such as severe heart failure and myocardial infarction, we will support and manage the installation of circulatory support devices such as IABP, VA-ECMO, and Impella.

It is an intervention for arteries in the leg.We carry out hygiene assistance work, and the CE is a system of two people, one for the surgical field and one for the outside.There are more types of sheaths, guidewires, and catheters than stent grafts, and many of them are thin and delicate devices.In the surgical field, these preparations and operation assistance are performed, and on the outside, we also monitor vital signs by polygraph, retrieve items, operate IVUS, and set up a system called CROSSER that penetrates the stenosis using mechanical vibration.

I am in charge of operation of the heart-lung machine used in cardiovascular surgery and the operation of medical equipment used during surgery.The goal is for one person in charge of cardiopulmonary bypass to be in charge of everything from operation to recording, and the layout of the equipment used makes this possible.In addition, regarding the information necessary for the operation of cardiopulmonary bypass during surgery, we have introduced a support system that converts the various data taken into the PC into the necessary information and displays it, leading to the safety of the cardiopulmonary bypass.

Aortic valve treatment for patients for whom surgical treatment is difficult.A catheter is used to place the aortic valve.We carry out hygiene assistance work, and in addition to preparing sheaths, catheters, and pacemakers, we also perform loading and crimping to attach valves.The circulatory caregiver monitors vital signs and pressures with a polygraph and operates the contrast injection device.For surgeries that require precision, we prepare artificial heart-lung machines and cardioplegia devices to respond to transitions to open-heart surgery in emergencies.Therefore, we will be engaged in a total of XNUMX people, XNUMX in the surgical field and XNUMX in the outer area.

In medical treatment for aortic aneurysms and dissections, a treatment device that combines a stent and an artificial blood vessel is placed in the affected area within the blood vessel.We carry out cleanliness assistance work, and it is a two-person system for the surgical field and the outside.In the surgical field, we prepare coils, catheters, and stent grafts for vascular embolization.

The aneurysm caused by the regurgitation of the venous valve in the leg is excised, and the cauterized vein is cauterized and occluded with a laser or medical glue.We carry out cleanliness assistance work, and the surgical field is a doctor and a two-person system.Assisting in guide wire operation, setting up the laser equipment, and extracting the equipment.Because this operation is performed under local anesthesia, the patient is conscious and uneasy, and there are many female patients.

Circulatory support devices are used for severe heart failure (severe respiratory failure).
Regarding ECMO (PCPS), we mainly support circulatory support and respiratory support. Regarding IABP, it is also used for support in OPCAB cases and for emergency catheterization in cardiology. Impella is also used alone or in combination with ECMO in emergency cases in cardiology.

CIEDs include pacemakers implanted in patients with bradyarrhythmia and ICDs (implantable cardioverter-defibrillators) implanted in patients with tachyarrhythmia [cardiac implantable electrical device].

At our hospital, we perform catheter ablation treatment for tachyarrhythmias such as AF (atrial fibrillation) and VT (ventricular tachycardia).Catheter ablation therapy treats arrhythmia by cauterizing the myocardium by using a catheter inserted from the thigh to the heart and applying high-frequency current from the tip of the catheter.

Blood purification, also called renal replacement therapy, is a therapeutic method that removes harmful substances accumulated in the body by various methods to improve the condition.At our hospital, clinical engineers mainly perform the treatment and management of the following blood purifications under the direction of doctors.
In HD operations, we perform everything from priming to puncture and return blood, and in CRRT operations, we manage anticoagulation, fluid replacement, etc. on a 24-hour basis.In addition, blood purification is performed by a clinical engineer from preparation to completion during treatment.
