Mr Marco Scarci · Diaphragmatic Plication · London

Breathless lying down. Told to “live with it.” You don’t have to.

A paralysed or raised diaphragm robs one lung of the room to breathe — worst when you lie flat, bend over, or get into water. Most patients are never told that an operation exists to fix it. Mr Marco Scarci performs keyhole diaphragmatic plication: tightening the slack diaphragm so your lung can expand again.

  • No GP referral needed
  • Most patients seen within one week
  • Recognised by all major insurers

The breathlessness with a pattern

Why it’s worse when you lie down

Your diaphragm is the main muscle of breathing. When it’s paralysed or weakened — often after heart or neck surgery, a viral illness, or sometimes with no cause ever found — it stops pulling down and instead sits high in the chest, squeezing the lung above it.

Sitting or standing, gravity helps hold things down and you cope. Lie flat, and the abdominal organs push the slack diaphragm even higher — which is why beds, bending down, and getting into water are exactly where your breathing fails you. That pattern isn’t anxiety and it isn’t lack of fitness. It’s mechanics — and mechanics can be fixed.

Been told you have a “raised hemidiaphragm” on an X-ray and then heard nothing more? That finding is often exactly this condition, waiting to be taken seriously.

Does this sound familiar?

  • Breathless lying flat — you sleep propped on pillows, or in a chair
  • Bending over — shoes, gardening, the dishwasher — leaves you gasping
  • Swimming or getting into water feels suffocating
  • Told you have a “raised diaphragm” on an X-ray — then nothing happened
  • It started after heart surgery, neck surgery or a bad viral illness
  • Treated for asthma, weight or anxiety — and none of it helped

Sudden or rapidly worsening breathlessness, chest pain, or blue lips — call 999 now. This page is about long-standing breathlessness that has already been investigated.

Fixing the mechanics

Keyhole diaphragmatic plication

“Nothing can be done” usually means “nothing I can do.” Plication is a long-established operation performed regularly in only a small number of specialist centres — which is why so many patients have simply never been offered it.

  • Diagnosis done properly first: breathing tests sitting and lying down, imaging, and the “sniff test” that shows the diaphragm moving the wrong way
  • Honest selection — not everyone benefits from surgery, and you’ll be told plainly which group you’re in
  • Keyhole approach — small incisions between the ribs instead of a large opening, meaning less pain and a faster recovery
  • Improvement many patients notice early — easier breathing lying flat — continuing to build over the following months
  • A short hospital stay and direct, personal follow-up until you’re back to stairs, sleep and swimming

The operation, in plain English

  • What plication is — the slack, floppy diaphragm is folded and stitched flat and tight, so it sits low and firm instead of ballooning into the chest.
  • What that achieves — the compressed lung finally has room to expand, and lying flat stops pushing the diaphragm up into it.
  • Who it helps — people whose paralysed or raised diaphragm is genuinely the cause of life-limiting breathlessness, confirmed by testing.
  • What it isn’t — not every raised diaphragm needs surgery. Honest assessment comes first, always.

Why patients choose Mr Scarci

A genuine subspecialty, not an occasional case

With over 20 years at the forefront of thoracic surgery, Mr Scarci operates on the chest exclusively. Diaphragm surgery is performed regularly in only a handful of UK centres, and it is a genuine subspecialty of his practice — he literally wrote a complete patient guide to diaphragmatic plication. He has performed more than 5,000 minimally invasive procedures and holds fellowships from four leading international surgical colleges.

“The goal is never just a better-looking X-ray. It’s sleeping flat, climbing the stairs, and getting back in the water — without thinking about your breathing.”

Patients come to him after years of unexplained breathlessness and being told to live with it. They leave with a mechanical explanation, an honest assessment — and, where surgery is right, a fix.

Your journey, step by step

New to private care? Here is exactly what happens — and how quickly.

Same day

First contact

Call, WhatsApp, or complete the form below. Namita, the practice manager, confirms your appointment, checks your insurance cover, and requests your existing X-rays, scans and breathing tests — so nothing is repeated unnecessarily.

Within one week

Consultation with Mr Scarci

Your consultation is with Mr Scarci himself — he will have reviewed your imaging before you arrive. Where needed, the confirmatory tests are arranged promptly: breathing tests sitting and lying down, and the “sniff test” that shows the diaphragm’s abnormal movement in real time.

You decide

An honest recommendation

If the tests show your diaphragm is genuinely the cause and surgery is likely to help, you’ll be told exactly why — and if it isn’t, you’ll be told that too. The decision is always yours. Insurance pre-authorisation is handled for you.

Weeks 2–4

Keyhole plication at whichever of five London hospitals suits you best, with a short hospital stay. Mr Scarci performs your operation personally and follows you up directly, with a staged plan back to full activity — stairs, sleeping flat, and swimming included.

Common questions

Frequently asked questions

What causes a paralysed diaphragm?

The most common causes are injury to the phrenic nerve — the nerve that drives the diaphragm — during heart or neck surgery, viral illnesses, and pressure from other structures in the chest. In a significant number of patients no cause is ever found. Part of a proper assessment is making sure nothing treatable is behind it before deciding on the diaphragm itself.

I was told nothing can be done. Has something changed?

Plication has existed for decades — the problem is access, not science. It’s performed regularly in only a small number of UK specialist centres, so many clinicians simply never see it done and understandably say “learn to live with it.” Being told nothing can be done very often means nothing can be done here. A specialist assessment settles whether it can be done for you.

Will the operation definitely help me?

Honestly: not everyone is a candidate, and that’s exactly what the testing is for. The best results come when the paralysed or raised diaphragm is clearly the cause of your breathlessness and the lung itself is healthy — the sitting-versus-lying breathing tests and sniff test predict this well. If the numbers say surgery is unlikely to help you, you’ll be told so plainly before anyone talks about operating.

What does the operation involve, and how long is recovery?

Through small keyhole incisions between the ribs, the slack diaphragm is folded and stitched flat and tight, giving the lung above it room to expand. Hospital stay is short, and most patients build back to normal activities progressively over the following weeks, with heavier exertion staged. Many notice the difference lying flat early, with improvement continuing over the months as breathing retrains. Your individual timeline is set out clearly at consultation.

How much will it cost?

Plication for symptomatic diaphragm paralysis is established, medically necessary surgery — Mr Scarci is recognised by all major UK insurers and pre-authorisation is handled for you. If you’re paying for yourself, you’ll receive a clear written quote before any treatment, covering the surgical, anaesthetic and hospital fees — no hidden extras.

Do I need a GP referral, and how quickly can I be seen?

No referral is needed if you’re paying for yourself; some insurers require one, and the team will guide you through it. Your appointment is confirmed the same working day you get in touch, and most patients are seen within one week — in person at five London locations, or by video for your first consultation if you’re travelling from further afield.
