Atrial myxoma

Iyo atrial myxoma ibundu risingaratidzi cancer kumusoro kwekuruboshwe kana kurudyi kwemoyo. Inowanzo kukura pamadziro inoparadzanisa mativi maviri emoyo. Rusvingo urwu runodaidzwa kunzi septum.

Iyo myxoma ndiyo yepamoyo yemoyo (cardiac) bundu. Izvi zvinoreva kuti bundu rakatanga mukati memoyo. Mazhinji mamota emoyo anotangira kumwe kunhu.

Zvipenga zvepamoyo zvepamoyo senge myxomas hazviwanzo. About 75% yemyxomas inoitika kuruboshwe atrium yemoyo. Iwo anowanzo kutanga mumadziro anopatsanura makamuri maviri epamusoro emoyo. Zvinogona kuitika mune dzimwe nzvimbo dzemukati-yemoyo zvakare. Atrial myxomas dzimwe nguva inobatanidzwa nevhavha yekuvhara stenosis uye atrial fibrillation.

Myxomas inowanzoitika kune vakadzi. Inenge 1 mu10 myxomas inopfuudzwa kuburikidza nemhuri (nhaka). Aya mamota anonzi emhuri myxomas. Ivo vanowanzoitika mune inopfuura chikamu chimwe chemoyo panguva, uye kazhinji chinokonzera zviratidzo pazera diki.

Mazhinji myxomas haazokonzere zviratidzo. Izvi zvinowanzo kuwanikwa kana chidzidzo chekufungidzira (echocardiogram, MRI, CT) ichiitwa kune chimwe chikonzero.

Zviratidzo zvinogona kuitika chero nguva, asi kazhinji zvinoenda pamwe neshanduko munzvimbo yemuviri.

Zviratidzo zvemyxoma zvinogona kusanganisira:

• Kufema kunetseka kana wakarara wakatsetseka kana kune rimwe divi kana rimwe racho
• Kufema kunetseka kana wakarara
• Kurwadziwa pachifuva kana kuoma
• Dzungu
• Kufenda
• Kunzwa kwekunzwa moyo wako uchirova (palpitations)
• Kupfupika kwemweya nekuita
• Zviratidzo zvinokonzeresa embolism yebundu zvinhu
  

Zviratidzo uye zviratidzo zvekuruboshwe atrial myxomas zvinowanzo kutevedzera mitral stenosis (kudzikira kwevhavha pakati peatrium yekuruboshwe uye kuruboshwe ventricle). Right atrial myxomas haawanzo kuburitsa zviratidzo kudzamara akura kuita akakura (mashanu masendimita yakafara, kana gumi nematanhatu masendimita).

Zvimwe zviratidzo zvinogona kusanganisira:

• Bluish ganda, kunyanya paminwe (Raynaud phenomenon)
• Kukosora
• Kukombama kwembambo kunoperekedzwa nekunyorova kweturu kuzvimba (klubbing) yeminwe
• Kupindwa nechando
• Minwe inoshandura ruvara pane kumanikidza kana nechando kana kushushikana
• Kazhinji kusagadzikana (malaise)
• Joint kurwadziwa
• Kuzvimba mune chero chikamu chemuviri
• Kurera huremu pasina kuyedza

Anopa hutano anoita bvunzo dzepanyama uye teerera kune moyo wako kuburikidza ne stethoscope. Mwoyo usina kujairika unonzwika kana kugunun'una kunogona kunzwika. Iyi mhere inogona kuchinja kana iwe ukachinja chinzvimbo chemuviri.

Kufungidzira bvunzo kunogona kusanganisira:

• Chest x-ray
• CT scan yechifuva
• ECG
• Echocardiogram
• Doppler kudzidza
• Mwoyo MRI
• Kuruboshwe moyo angiography
• Right moyo angiography

Iwe unogona zvakare kuda kuongororwa kweropa kusanganisira:

• Yakazara kuverenga kweropa (CBC) - inogona kuratidza kupererwa neropa uye kuwedzera masero eropa machena
• Erythrocyte sedimentation mwero (ESR) - inogona kuwedzerwa

Kuvhiya kunodiwa kuti ubvise bundu, kunyanya kana riri kukonzera kusagadzikana kwemoyo zviratidzo kana embolism.

Isina kurapwa, myxoma inogona kutungamira kune embolism (tumarara maseru kana hove inotsemuka ichifamba muropa). Izvi zvinogona kutungamira mukuvhara kweropa kuyerera. Zvidimbu zvebundu zvinogona kuenda kuuropi, ziso, kana makumbo.

Kana bundu rikakura mukati memwoyo, rinogona kuvhara kubuda kweropa, zvichikonzera zviratidzo zvekudzivirira.

Zvinetso zvinogona kusanganisira:

• Arrhythmias
• Pulmonary edema
• Peripheral emboli
• Kuvharika kwemagetsi mavharuvhu

Bundu repamoyo - myxoma; Bundu remwoyo - myxoma

• Kuruboshwe atrial myxoma
• Kurudyi atrial myxoma
