From balloon expansion to coronary stent implantation, from arrhythmic catheter ablation to structural heart disease without chest treatment, as the most revolutionary breakthrough in modern medicine, cardiovascular intervention technology is developing towards a more minimally invasive and refined direction.
Medicine is used to save the world, and skills are important to be exquisite. On the central map of life in the heart, the Department of Cardiology of Shandong First Medical University (Shandong Provincial Hospital, hereinafter referred to as "Provincial Hospital") continues to seek innovation and change, and bravely climb to the top to lead hard-core cutting-edge technologies in the professional field and protect patients' heart health.
Break through the coronary intervention barrier
For patients with complex coronary lesions, as an effective means to improve myocardial blood flow perfusion, coronary interventional treatment has become the first-line treatment choice for coronary lesions. However, in recent years, the increase in patients with complex coronary artery lesions has become a clinical barrier that needs to be overcome in the field of coronary interventional treatment.
Yuan Haitao, director of the Department of Cardiology at the Provincial Hospital Affiliated to Shandong First Medical University, introduced that with the progress of population aging, the number of patients with coronary calcification, chronic occlusion of coronary artery, as well as intrastent, bridge restenosis and even occlusion after coronary stent implantation and coronary bypass surgery is also increasing. In the past, the treatment methods for this part of patients were limited, clinical treatment was difficult, and the clinical prognosis was not good.
Starting from the needs of patients, in order to clear the lesional blood vessels that hinder patients' lives, the Department of Cardiology of the Provincial Hospital has continuously applied advanced technology to the clinic, turning "impossible" into "possible". Excimer laser plaque ablation (ELCA) is one of them.
"This technology uses the principles of photochemistry, photothermal, and photomechanical to form light pulses, sound waves, and cavitation of bubbles, ablation and loosening of fiber calcification lesions, thrombosis, etc., making the stent easier to transport, which is conducive to the full expansion of the stent and avoiding problems such as reflux or distal embolism, so that patients with complex coronary lesions can successfully undergo coronary intervention treatment." Yuan Haitao said that in addition to patients with intrastent restenosis, poor stent dilation, severe calcification lesions, lesions that cannot pass through the balloon and chronic complete occlusion, ELCA is also suitable for patients with venous vein vein restenosis after coronary bypass surgery.
"Handling interventional treatment of venous bridle blood vessels is a very high-risk operation. Once the balloon expands, it is very easy to cause the fall of soft plaques, causing serious complications." Yuan Haitao said that excimer laser plaque ablation surgery is safer than traditional lasers, allowing more complex coronary patients to obtain coronary revascularization through interventional minimally invasive treatment.
Make the heart stop beating
Accurate ablation and protecting the rhythm of life
Arrhythmia is a high-frequency word in cardiology.
At the end of 2021, the Department of Cardiology of the Provincial Hospital successfully carried out the first emergency organ ventricular ablation surgery in our province for a patient with a ventricular tachycardia electric storm, making the patient safe.
Yuan Haitao introduced that in clinical practice, radiofrequency ablation of atrial fibrillation, paroxysmal ventricular velocity, frequent ventricular premature beats, ventricular tachycardia, etc. are mostly elective surgeries, and emergency radiofrequency ablation is rarely used in clinical practice, and radiofrequency ablation of rapid electric storms in emergency rooms is more difficult.
3D mapping system performs radiofrequency ablation of complex arrhythmia and atrial fibrillation, left atrial atrial appendage blocking in patients with stroke , zero-ray green electrophysiological treatment, "one-stop" combination treatment of radiofrequency ablation and left atrial atrial appendage blocking in patients with special atrial fibrillation, complex electrophysiological diagnosis and treatment technologies such as Xi'an and left bundle branching... The first development of advanced technologies has made them confident to charge forward at critical moments.
Fast and passion interpret miracles of life. As a key discipline in Shandong Province and a specialty in improving the diagnosis and treatment capacity of difficult diseases in Shandong Province, the Department of Cardiology of the Provincial Hospital has been deepening the construction of sub-specialties in recent years and is committed to creating an integrated diagnosis and treatment model for cardiovascular diseases.
Hard failure may not only be the end stage of heart disease development, but may also evolve from other diseases. Only by identifying the reasons behind it can we achieve precise treatment.
"We successfully confirmed the first ATTR myocardial amyloid degeneration and wild-type patients in the province, and their symptoms were progressive heart failure." Yuan Haitao said that the two patients had previously been seeking medical treatment and failed, but after successful diagnosis, they were given targeted drug treatment, and their heart function had been significantly improved.
Change the "heart door" without opening the chest
leads the treatment direction of structural heart disease
One thin guidewire after another accurately passes through complex blood vessels, and opens up the door of life for one patient after another between the square inch of the heart forbidden area. It is also through this thin guidewire that the treatment of structural heart disease bid farewell to the traditional era of "major surgery".
Yuan Haitao introduced that the aortic valve is the most important valve in the human body. Once it goes on strike, it will lead to a decrease in heart function and other parts of the body may not be able to obtain enough blood supply. However, due to rheumatic fever , birth defects, valve aging and infection, there are many patients with aortic valve lesions in clinical practice. Moreover, with the aging of the population and the increase in life expectancy, the number of this part of the patient is still increasing.
The emergence of the advanced technology of transcatheter aortic valve replacement (TAVR) has allowed those patients at high risk of elderly patients, complex comorbidities, and surgical contraindications to get rid of the regret of being unable to open the chest and replace the aortic valve.
It is reported that patients with TAVR surgery do not need to be opened. Through interventional catheter technology, only femoral artery is punctured, and the assembled artificial heart valve is transported to the aortic valve position in retrogradely, replacing the original aortic valve with a diseased aortic valve to restore valve function. The operation time is short, which avoids in vitro circulation of , and does not require blood transfusion. The patient can go to the ground to move the next day and recover quickly after the operation.
The successful implementation of cutting-edge hard-core technologies has saved the lives of countless patients. On the road to innovative development of medical science, there have never been a lack of courageous advances. The Department of Cardiology of the Provincial Hospital will always take protecting health as its mission, anchor the forefront of professional fields, and pave the "heart path" for more patients with "heart disease".
