Kodi valavu ya mtima wanu ya mitral ndi 'yomasuka' pang'ono? (Mitral Valve Prolapse) - Tiyeni tikambirane za izi!

Kodi nthawi zina mumamva kupsinjika pang'ono pachifuwa panu, kuvutika kupuma pang'ono, kapena kusintha kwa kugunda kwa mtima wanu? Izi zitha kukhala chifukwa cha kusintha pang'ono kwa valavu yaying'ono mumtima mwanu. Anthu ambiri sadziwa nkomwe za izi, koma ndikofunikira kwambiri kudziwa. Musadandaule, lero tikambirana za vutoli (Mitral Valve Prolapse) mwachidule.

Kodi Mitral Valve Prolapse ndi Chiyani?

Mwachidule, mtima wathu uli ndi valavu yotchedwa Mitral Valve . Imagwira ntchito ngati chitseko. Ili kumbali yakumanzere ya mtima pakati pa chipinda chapamwamba (atrium yakumanzere) ndi chipinda chapansi (ventricle yakumanzere). Vavu iyi imathandiza kuyenda kwa magazi oyera komanso okometsera kuchokera ku atrium yakumanzere kupita ku ventricle yakumanzere.

Tangoganizirani, valavu iyi ili ndi ma flap awiri (tipepala tating'ono) . Ili ngati zitseko ziwiri. Nthawi iliyonse mtima ukagunda, ma flap awa amatseguka ndikutseka. Mu vuto lotchedwa Mitral Valve Prolapse (MVP), ma flap awa satseka bwino, ndipo amagwera pang'ono kumanzere kwa atrium. Ali ngati chitseko chomwe sichitseka bwino. Izi zingayambitse valavu kuti isatseke bwino.

Matendawa (MVP) si oopsa monga momwe mungaganizire. Amakhudza anthu pafupifupi 2 mpaka 3 mwa anthu 100 mwa anthu onse. Anthu ambiri amakhala opanda zizindikiro zilizonse ndipo sadziwa ngakhale pang'ono kuti ali nawo. Izi zili choncho chifukwa valavu yawo ikugwirabe ntchito bwino. Komabe, kwa anthu ena, matendawa akakula kwambiri, zizindikiro zimatha kuwoneka ndipo chithandizo chingafunike. Nthawi zina, lingaliro lochita opaleshoni lingakhale loopsa, koma nkhani yabwino ndi yakuti pali anthu ambiri omwe apambana opaleshoni yamtunduwu.

Kodi zizindikiro za izi ndi ziti?

Anthu ambiri omwe ali ndi MVP samakhala ndi zizindikiro zilizonse, koma ena amatha kukhala ndi zizindikiro monga:

• Kupweteka pachifuwa: Si kupweteka kwakukulu ngati matenda a mtima, koma kungamveke ngati kusapeza bwino kapena kupanikizika pachifuwa.
• Kuvuta kupuma (kupuma movutikira): Mungamve ngati mukulephera kupuma, makamaka mukamachita masewera olimbitsa thupi kapena kukwera masitepe.
• Chizungulire: Mungamve mwadzidzidzi ngati mutu wanu ukuzungulira.
• Kutopa: Mungamve kutopa komanso kusakhala ndi moyo.
• Kugunda kwa mtima: Izi ndi zomwe anthu ambiri amakumana nazo. Tangoganizani kuti mtima wanu ukugunda mofulumira mwadzidzidzi, kapena mukumva mtima wanu ukugunda kunja, kapena chifuwa chanu chingamve ngati chikugunda.

Chofunika kwambiri ndichakuti si aliyense amene ali ndi zizindikirozi amene ali ndi vuto lalikulu (MVP). Nthawi zina sipangakhale ubale wofunikira pakati pa zizindikirozo ndi kuopsa kwa vutoli. Komabe, ngati muli ndi zizindikiro izi, ndikofunikira kukaonana ndi dokotala.

Kodi ndi zifukwa ziti zomwe zimayambitsa kutsika kwa mitral valve?

Chifukwa chachikulu ndi kufooka kwa minofu ya valve. Izi zimatchedwa myxomatous degeneration mu sayansi ya zamankhwala. Sizikudziwika bwino chifukwa chake minofu iyi imafooka. Nthawi zina imatha kukhala yobadwa nayo. Izi zikutanthauza kuti vutoli likhoza kuperekedwa kuchokera kwa makolo kupita kwa ana. Ofufuza apeza majini angapo okhudzana ndi vutoli (MVP). Mwachitsanzo, majini otchedwa (FLNA), (DCHS1), (DZIP1) ndi (PLD1) apezeka kuti ali ndi gawo pa izi.

Komanso, anthu omwe ali ndi matenda enaake olumikizana ndi minofu amathanso kukhala ndi vutoli (myxomatous degeneration). Mwachitsanzo:

• Matenda a Marfan
• Matenda a Ehlers-Danlos
• Matenda a Loeys-Dietz

Popeza anthu omwe ali ndi matendawa ali ndi zofooka zina m'thupi, zimathanso kukhudza ma valve a mtima.

Ndani amene ali pachiwopsezo chachikulu cha matendawa (MVP)?

Mitral Valve Prolapse ingakhudze anthu azaka zilizonse. Anthu ena amabadwa ndi vutoli, makamaka omwe ali ndi matenda olumikizana omwe atchulidwa kale. Kuphatikiza apo, matenda otsatirawa angapangitse kuti pakhale chiopsezo cha MVP:

• Matenda a mtima otchedwa rheumatic heart: Matenda omwe angakhudze mtima pambuyo pake ngati matenda a pakhosi sanachiritsidwe bwino.
• Scoliosis: Matenda omwe msana umapindika.
• Matenda a Graves: Chithokomiro chogwira ntchito mopitirira muyeso.

Ngakhale kuti MVP imapezeka kwambiri mwa akazi, amuna amakhala ndi mwayi waukulu wopeza mitral regurgitation (magazi otuluka m'mbuyo) omwe amayamba chifukwa cha izi.

Kodi izi zingayambitse mavuto otani?

Vuto lalikulu lomwe limachitika mwa anthu omwe ali ndi MVP ndi mitral regurgitation. Mwachidule, valavu siitseka bwino, zomwe zimapangitsa kuti magazi atuluke kuchokera kumanzere kupita ku atrium yakumanzere. MVP ndiye chifukwa chachikulu cha vutoli. Ngati kutuluka kwa madzi kuli kwakukulu, opaleshoni kapena chithandizo china chingafunike kuti valavuyo igwire ntchito bwino.

Anthu omwe ali ndi Mitral Valve Prolapse ndi Regurgitation ali pachiwopsezo chokhala ndi mavuto monga:

• Kulephera kwa mtima: Mtima sungathe kupompa magazi okwanira kupita m'thupi.
• Matenda a mtima: Matenda a mkati mwa mtima kapena ma valve a mtima.
• Kugunda kwa mtima kosakhazikika: Kugunda kwa mtima kosakhazikika.
• Kusakhazikika kwa mtima: Uku ndi kugunda kwa mtima kosakhazikika, komwe nthawi zina kungayambitse imfa yadzidzidzi ya mtima.
• Stroke: Kusokoneza kayendedwe ka magazi kupita ku ubongo.

Kodi matendawa (Mitral Valve Prolapse) amawapeza bwanji?

Madokotala amazindikira matenda a MVP mwa kukupimani ndikukuyesani. Dokotala amatha kudziwa zambiri pomvetsera mtima wanu pogwiritsa ntchito stethoscope . Ngati muli ndi MVP, dokotala wanu angamve phokoso la 'click' pamene mtima wanu ukugunda, kutsatiridwa ndi 'murmur' (phokoso ngati mphepo yofewa ikuwomba mumtima). Chifukwa cha phokoso losiyanali, MVP imatchedwanso "click-murmur syndrome."

Akamakupimani, dokotala adzakambirananso za mbiri yanu yakale yachipatala komanso mbiri yanu yachipatala ya m'banja . (MVP) Chidziwitsochi n'chofunika kwambiri chifukwa nthawi zina chimapezeka m'mabanja.

Ngati dokotala wanu akukayikira kuti muli ndi vuto la MVP kapena vuto lina la valavu, adzalamula kuti muyesedwe kamodzi kuti atsimikizire matendawa.

Ndi mayeso ati omwe amachitidwa pa izi?

Mayeso akuluakulu omwe amagwiritsidwa ntchito pozindikira MVP ndi echocardiogram . Izi zimagwiritsa ntchito ukadaulo wa ultrasound kuti aone kapangidwe ndi ntchito ya mtima. Mutha kukhala ndi mtundu umodzi kapena mitundu yonse iwiri:

• Kujambula kwa mtima kwa Transthoracic: Izi zimaphatikizapo kuyika chojambulira cha ultrasound pamalo osiyanasiyana pachifuwa chanu kuti mujambule zithunzi za ma valve ndi zipinda za mtima.
• Transesophageal echocardiogram: Izi zimaphatikizapo kupereka transducer yaing'ono ya ultrasound mummero wanu kuti mujambule zithunzi zomveka bwino.

Kuphatikiza apo, dokotala wanu angakupatseni mayeso ngati awa kuti mudziwe zambiri zokhudza mtima wanu:

• Electrocardiography (ECG/EKG): Imafufuza momwe magetsi a mtima amagwirira ntchito.
• X-ray ya pachifuwa.
• Kutsegula mitsempha ya mtima: Chitoliro chopyapyala chimalowetsedwa m'mitsempha ndi m'zipinda za mtima kuti chizifufuze.

Kodi izi zimachiritsidwa bwanji?
