1
If you have a severe problem with the aortic valve in your heart, your doctor may recommend a transcatheter aortic valve implantation, or TAVI.
2
It's also known as transcatheter aortic valve replacement, or TAVR.
3
Your aortic valve is one of the four valves in your heart.
4
It lies between your left ventricle, or lower left chamber, and the large blood vessel supplying oxygen -rich blood to your body called the aorta.
5
When your left ventricle contracts during each heartbeat, it pushes blood through three flexible cup -like leaflets that make up your aortic valve.
6
When your left ventricle relaxes, your aortic valve closes to prevent blood from flowing back into your left ventricle.
7
As you get older, your aortic valve may develop deposits of calcium that cause your leaflets to get thicker and less flexible.
8
In this condition, your leaflets may not open fully.
9
This condition, called calcific aortic valve stenosis, creates a narrowed opening that reduces the amount of blood flowing into your aorta and out to your body.
10
As a result, the wall of your left ventricle thickens
11
because it has to work harder to pump blood through the narrowed valve opening.
12
At the beginning of your procedure, your doctor will make a small incision in your groin.
13
After creating an opening in a blood vessel called the femoral artery, your doctor will insert a flexible tube called an introducer sheath.
14
Through the sheath, your doctor will insert a flexible guide wire into your femoral artery.
15
The guide wire will be passed through your femoral artery, all the way up to your aorta.
16
Then the guide wire will be pushed through the opening in your aortic valve and into your left ventricle.
17
Your doctor will use the guide wire to pass a flexible tube, called a catheter, through your aortic valve.
18
A balloon on the tip of the catheter will be inflated
19
to widen the opening in your aortic valve to push the valve leaflets to the sides.
20
After deflating the balloon, your doctor will remove the catheter.
21
The replacement valve consists of a tissue valve surrounded by a wire mesh called a stent.
22
The replacement valve will be compressed and placed on the tip of another catheter.
23
This catheter will be inserted through your aortic valve.
24
When the catheter reaches the opening in your aortic valve, your doctor will inflate a balloon underneath the replacement valve to expand it and the stent.
25
After placement of the new aortic valve, your doctor will deflate the balloon.
26
The stent will support and secure the replacement valve in place.
27
The catheter and guide wire will be removed.
28
At the end of the procedure, the introducer sheath in your groin will be removed, and your skin incision will be closed.
29
You will have another incision on the other side of your groin, through which instruments were inserted to monitor your heart during the procedure.
30
This skin incision will also be closed.
31

シャドーイングとは？英語上達に効果的な理由

シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
